Background technique

Light emitting diodes have long been used individually or in groups as backgrounds or as indicator lights in electronic devices. Light emitting diodes are ideal for electronic applications because of efficient light generation, durability, long life, and small size.

Higher power LEDs are also used in applications that require more intense light emission. In some high-brightness applications, multiple fixed groups of series-connected light-emitting diodes, each with a common voltage drop, are used to achieve the desired light emission. The groups are formed along a rail or rail, the entire rail or rail being replaceable by the manufacturer if any part of the rail is defective. If the manufacturer is located far away, or if there is a backlog of repairs, it may take a long time to get such repairs. Such applications can be indoor or outdoor applications. Electrically connected LEDs operate as a single application and are sealed and protected as a single linear group. If only one diode fails, the entire bank of fixed LEDs needs to be replaced.

In an outdoor arrangement, the LED array may consist of groups of LEDs. One or more of the diodes may be non-functional due to wear, manufacturing defects, or because they have been vandalized. It is difficult to detect if one or more LEDs are inoperative due to their brightness. Furthermore, an organization such as a municipal government may have many such arrays operating over a wide geographic area. Although reports from citizens can be collected to help identify LEDs that need replacement, it is difficult to ensure that all non-functioning LEDs are replaced. Thus, maintenance becomes a difficult problem.

Detailed ways

In the following description, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration specific embodiments in which they may be practiced. The details of these embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, it being understood that other embodiments may be utilized and structural, logical and electrical changes may be made without departing from the scope of the invention. Accordingly, the following description of exemplary embodiments should not be taken in a limiting sense, the scope of the invention being defined by the appended claims.

This application describes several embodiments of light fixtures, some having an array of replaceable light emitting diode modules. Maintaining a light fixture includes identifying high brightness light emitting diodes requiring replacement in a light fixture having a large number of light emitting diode lighting arrays having a plurality of electrical receptacles supported by a base plate and forming the electrical receptacle substrate. The ID of the light fixture is provided, and the light fixture sends the ID and an indication that the light emitting diode needs to be replaced. The ID uniquely identifies the luminaire fixture and has an associated location of the luminaire.

Further embodiments are described in which the light is displayed according to a program that may represent a pre-recorded outdoor light sequence, such as a sunny day with clouds moving past the sun. The result is a simulated daylight in sunlight. The natural variation in color and brightness of light provided by such recordings or programs can provide a relaxing environment. Light can affect the production of melatonin through the pineal gland in the body. Melatonin is important in regulating circadian rhythms and sleep cycles. Natural sunlight, including its variations, can affect melatonin production. By simulating such natural daylight, the productivity of office and other indoor workers can be increased.

Example of a replaceable module

In one set of embodiments including replaceable LED arrays, high brightness LEDs for producing large amounts of light to illuminate large areas such as parking lots, parking pavements, highways, streets, stores, warehouses, gas station ceilings, etc. A light fixture is shown generally at 100 in FIG. 1 . FIG. 1 is a top view of a light fixture 100 that includes a rigid substrate 105 . A plurality of high-brightness LEDs can be packaged into a module 110, which can be seen through a cylindrical cooling structure 120 in FIG. 1 . In this view, the modules provide light directed away from the surface of the drawing.

In one embodiment, cooling structure 120 and module 110 are supported by base plate 105, which in one embodiment is formed of aluminum to provide both strength and thermal conductivity to keep module 110 cool. A board 130 , such as a circuit board, may be placed integral to the cooling structure 120 and provide suitable electrical conductors between the modules 110 . In one embodiment, the board 130 may be a standard circuit board and metallized to form the conductors. In one embodiment, the frame 140 may be formed around and integrated with the substrate.

The base plate and cooling structure 120 may be formed of aluminum or other material that provides adequate structural support, is lightweight and conducts heat well. A plurality of electrical sockets 150 may be formed on the substrate between the cooling structures and in one embodiment secured to the board 130, forming a substrate of the electrical sockets 150 that may be electrically interconnected in two dimensions through the board 130. even. One or more LEDs 110 may be individually removed and replaced within the substrate within any individual electrical socket, which in one embodiment may be rigid and may be secured to the substrate 105 by epoxy or other filler material Inside, the epoxy or other filler material has suitable thermal conductivity and retention properties to ensure that the board 130 is firmly held in place over the socket 150 .

As can be seen in Figure 1, more sockets than can accommodate modules can be arranged in different patterns. Additional outlets provide flexibility for a variety of lighting needs. In one embodiment, the outlet may provide for the use of an optimal number of modules to provide mass lighting for outdoor applications, such as parking lots, parking pavements, highways, streets, stores, warehouses, gas station canopies. For small scale lighting applications, fewer modules can be used in fewer sockets. For each socket and module configuration, the electrical connections can be changed to provide the correct voltage to each module.

FIG. 2A is a top view of a base plate 105 including a socket 150 for a light emitting diode module according to an exemplary embodiment. As shown, the base plate 105, where the cooling structure 120 and socket 150 have a depth to them to provide structural support for both, may be formed from a thermally conductive material. The sockets are disposed between the cooling structures so that heat can be easily conducted to the cooling structures.

FIG. 2B is a top view of a circuit board 130 for mating with the substrate of FIG. 2B according to an exemplary embodiment. In one embodiment, board 130 has openings corresponding to cooling structures 120 and sets of connectors corresponding to receptacles when connected to the substrate.

Each individual LED module 300 is shown in more detail in FIG. 3 , and the module 300 may include a base 310 and a LED 320 . The base may be constructed and arranged to matingly and electrically engage within the electrical receptacle 150 . The light emitting diode module 300 can be mated in the electrical receptacle 150 through a variety of different types of connections. In various embodiments, LEDs 320 may be of different colors, most colors of LEDs are currently commercially available.

Base 310 of LED module 300 may include heat dissipating radial fins 330 to dissipate heat away from electrical socket 150 and leads or contacts 340 for connections to board 130 to provide power to the light emitting diodes 320. Because the LED module 300 can be used in both interior and exterior applications, some embodiments can withstand a wide range of ambient temperatures as long as they are not too hot for proper operation, and can also withstand extreme weather conditions, including rain , snow, frost, dust, winds up to about 150 mph, and more, while still glowing efficiently. Heat dissipating fins 330 may extend radially from the top of base 310 to draw heat away from LEDs 320 and act as a heat sink to prevent damage to LEDs or surrounding components. The heat sink can be attached to a heat sink ring 350 which can provide stability and measure allowing easy handling when assembling or replacing the module 300 in the socket 150 .

FIG. 4 is a simplified schematic representation of a connector board, shown generally at 400, for a high brightness light emitting diode array. Openings in the plate for cooling structures are not shown. In one embodiment, the board 410 is provided with a positive connector 415 and a negative connector 420 for connection to a power supply and driver not shown. The positive connector 415 is electrically connected to a first receptacle 430 via a connector 425 . Assuming 24 volts of power across connectors 415 and 420 , ten receptacles are electrically connected in series, with receptacle 435 at the end, which in turn connects to negative connector 420 through connector 440 . These connections, along with intermediate series connections to eight other sockets, provide a voltage drop of 2.4 volts DC for each LED plugged into the socket. This ensures that each LED will receive the correct voltage for proper operation.

If different power levels are available, and/or different LEDs are to be used at different voltage drops, a simple way is to divide the voltage drop by the power to determine how many outlets should be connected in series. The board can then be reconfigured to match the number of sockets required. As shown in FIG. 4 , there are four such groups of series sockets, with each group connected between positive and negative connectors 415 and 420 . Many other different configurations are also possible.

In yet another embodiment, an adaptive power supply can be used, and the number of modules in series can be varied as the power supply is adapted to drive the correct output required by the module. All sockets can be made active while such drivers and modules are inserted as desired. In some embodiments, modules may be removed or added in series if required for compatibility with power supplies and drive circuits. In one embodiment, all outlets can be wired in series. The series connection can be maintained using a plug to a short circuit open socket, or a suitable bypass circuit can be used if a module in the socket is faulty, or the socket is not used in some lighting applications.

In one embodiment, the present sockets are arranged in an oval shape, but many other shapes could easily be used. Plate 410 may be suitably shaped to conform to the receptacle while providing a shape suitable for aesthetic design purposes. Similarly, the base plate 105 as shown in FIG. 1 may also take many different shapes, from rectangular or circular as shown, to almost any desired shape, such as, to name a few, a "u" shape or a kidney bean shape. In addition, one or more rows of sockets may also be provided in an elongated shape.

In some embodiments, base plate 105 and plate 130 may be made of any weatherproof metal such as aluminum or other suitable metal for heat dissipation. In one embodiment, the electrical receptacles are rectangular substrates evenly spaced relative to each other and may be part of the cast substrate 105 .

In one embodiment, electrical receptacle 150 may be designed to accommodate removable and replaceable LED modules using different connection types including, but not limited to, screw-in or Edison-type connections, pin-type connections, and card Buckle or friction connection, as shown at 500 in FIG. 5 .

In FIG. 5 , module 505 is secured by guide pins 510 , 515 into mating connectors 520 , 525 in guide plate 530 . The guide pins and mating connectors provide a snap or friction connection, holding the module 505 securely within the receptacle 535 . In one embodiment, the mating connectors 520 and 525 may be provided with guides 526 to ensure that the pins are properly inserted and guided into the female mating connectors 520, 525, which in one embodiment may be made of copper and are loaded from the side by springs to retentively engage the pins 510,515. In various embodiments, the female connector may extend partially above the board, or within the board. When in the board, the board basically has an opening that is larger than the diameter of the pin but narrows to the point where it mates with a snap or friction fit portion of the connector.

In one embodiment, a sealing member such as a ring, disk or gasket 540 is located between the surface of the module 505 and the receptacle 535 . When the module 505 is fully secured by the pins and mating connectors, the sealing member 540 is compressed to provide a watertight seal and protect the electrical connections from elements that could compromise the electrical contacts made by those connections. In various embodiments, the sealing member may be formed from a compressible material such as rubber, latex, Teflon, silicone rubber, or the like. To provide greater tolerances regarding the thickness of the board 530 and the distance of the connectors 520, 525 from the module when sealed in the receptacle, in some embodiments the compressible sealing member may be formed with a hollow center. In further embodiments, the sealing member operates to provide a seal over a wider depth of compression.

In yet another embodiment, the plug may be formed in the same shape as the module 505, with pins that mate with the mating connectors 520, 525 to provide a seal around the receptacle that is not used to operate the module. The pins of such a plug may be electrically insulated from each other to ensure that no short circuit occurs, or a short circuit may be provided to properly maintain a series connection in a pre-wired string of sockets. Such plugs ensure the integrity of all electrical connections in the board when properly used in all sockets that do not contain module 505 .

The ability to easily remove and replace modules in a sealed manner facilitates maintenance and repair of high brightness large scale substrate lighting solutions. Each individual LED module is removable from a separate socket within the base. Because, the individual LED modules can be replaced individually, there is no need to replace the entire pack or group of electrical sockets or modules if one module fails. Simple removal and replacement of failed modules can be performed quickly. Furthermore, LED modules emitting different colors can be rearranged within the substrate to produce different color arrangements without requiring replacement of the entire package of electrical sockets or modules.

Module 505 also shows a lens 550 that connects to the light emitting diodes within module 505 and provides a protective seal. The lens 550 may be placed on or adhered to the fill material surrounding the actual light emitting diode. When the filler material is cured, the lens can be securely fastened to the filler material. Many different kinds and shapes of lenses can be used. For large-area high-brightness lighting applications, lenses can be shaped to provide directional illumination, or to provide a widely dispersed beam that, when all modules in an array are properly oriented, provides the desired pattern of light to illuminate large areas, such as parking lots , Parking pavement, highway, street, shop, warehouse, gas station ceiling. Similarly, different lenses may be used for many different applications, for example for forming spotlights where it may be desirable to narrow the beam from each module.

The module 505 may also be provided with guides 545 which, together with mating guides in the socket, ensure that the module is inserted into the socket in the desired orientation. In one embodiment, guides 545 may be ridges extending outward from the module and cooperating with grooves in the module to provide guidance. In other embodiments, the grooves may be on the module and the mating ridges are on the socket. In various embodiments, many different shapes and combinations of grooves and ridges may be provided.

In yet another embodiment, plate 530 may be formed with filler material 560 , and additional plate 565 . Such a combination provides sealing of the conductors on the board and protects them from the elements.

FIG. 6 is yet another embodiment of a screw-in connector 600, which is commonly referred to as an Edison connector. A sealing member is also provided. In this embodiment, a simple cylinder can be used as the socket, and the top portion of the module and sealing member are simply pressed against the top of the socket when the module is fully engaged into a retaining relationship with the socket.

Fig. 7 is yet another embodiment of a pin-type connector 700, also having a similarly compressed sealing member.

FIG. 8 is an alternate embodiment 800 of the module 505 of FIG. 5 in which a sealing member 805 is positioned over a base 810 of the module 800 . These pins are also similar in that the pins provide a friction fit with the connectors on the board.

Fig. 9 is a schematic block diagram of the bottom of a socket 900 into which a pin of a module can be inserted. Six openings 905 are shown, representing connectors for pins of three different orientation sets. As shown, there are slots to provide guidance so that the module can be inserted correctly. In one embodiment, the board may have three or more different sets of wires to provide different circuits for different types of LED modules, such as different colored LEDs. The different circuits can then be used to independently control the different colored LEDs in a desired manner and, as will be discussed further below, provide illumination of different colors and intensities. In one embodiment, sets of pins are formed with different orientations along the slots to ensure that only one color light fixture is inserted into the socket in the desired manner to connect to the desired circuit. In further embodiments, the signals to control the light fixtures may be multiplexed onto one or more control wires to provide a separate circuit for the desired control of the light fixtures without requiring the light fixtures to be plugged into sockets in different arrangements. Also, sockets can be pre-wired for specific types of LED modules. In other embodiments, the receptacle may be twisted or otherwise oriented within the receptacle to contact the desired circuit.

In one embodiment, the circuit board may have 120 available sockets for the modules to allow flexibility in positioning the modules. In some embodiments, different types of modules, such as modules of different colors, may be scattered throughout the board. In one example, 90 white light modules and 30 yellow light modules can be properly plugged into sockets and independently controllable either through separate circuits or through predetermined wiring. In alternative embodiments, many other combinations and total numbers of sockets per board may be used, including boards made, for example, of 60-90 sockets, 90-120 sockets, and 120-160 sockets.

FIG. 10 is an alternate embodiment of a module 1000 plugged into a receptacle 150 . In this embodiment, the receptacle 150 has a flange 1005 at the module receiving end which operates to provide a surface for compression of a sealing material 1010 between the flange 1005 and a ring 1015 formed on the base of the module 1000 . The socket 150 also has a second flange 1020 formed on a second end of the abutment plate 1025 . In this embodiment, pins 1027 , 1028 extend a short distance from body 1030 of module 1000 to mate with female connectors 1035 and 1040 . In some embodiments, the female connectors 1035 , 1040 may extend beyond the circuit board into the compressible adhesive material 1045 .

FIG. 11 shows an alternative module 1100 in which female connectors 1105 and 1110 extend significantly to compliant adhesive material 1115 between plates 1120 and 1125 . Material 1115 provides additional resilience to maintain retention on the pins via female connectors 1105 and 1110 . In one embodiment, the material 1115 may be a liquid rubber, latex or silicon type material that is flexible and provides good adhesion on the board.

FIG. 12 is a top view of sets of female connectors 1210 on board 1215 for mating with pins of module 1230 . A slot 1220 is also provided in the side of the receptacle corresponding to the connector in preparation for guiding a module 1230 having a pair of ridges 1235 . In one embodiment, by turning and inserting the module, the module can be connected to one of three different sets of connectors. In one embodiment, the locations where modules can be inserted may be referred to as A, B, and C. Position A can correspond to the wiring on the board so that 80 modules can be plugged into the sockets to provide illumination for applications requiring that amount of light. Location B can accommodate 120 modules, while location C can accommodate 160 modules. The detailed number of modules may vary considerably in different embodiments. In one embodiment, two slots 1220 may be provided that can be rotated into different positions to ensure that the module is properly inserted depending on the desired application. Templates are also available for each different configuration to assist the user in inserting the modules into the correct sockets. After using the stencil, the remaining open sockets can be plugged in to ensure that the light fixture is completely sealed.

lighting program

In one embodiment, the functions or algorithms described herein can be implemented in software or a combination of software and human-implemented programs. The software may consist of computer-executable instructions stored on a computer-readable medium such as memory or other kind of storage device. In addition, such a functionally corresponding module is software, hardware, firmware or any combination thereof. Various functions may be performed in one or more modules as desired, and the described embodiments are merely examples. The software may execute on a digital signal processor, ASIC, microprocessor, or other type of processor running on a computer system such as a personal computer, server, or other computer system.

In various embodiments of the invention, one or more lighting programs are used to control both the color and brightness of light emitted from one or more arrays of light emitting diode (LED) light fixtures. In one embodiment, the color and brightness of light can be measured in an outdoor environment over the course of a day from morning to evening. Both color (as measured in Kelvin) and photometers are used to digitally measure light color and brightness over the course of a day. In one embodiment, several such days and nights are recorded. In one embodiment, such seven-day values for lit days can be recorded and then used sequentially or randomly to control LED luminaires in an indoor space such as an office. Such days may include clouds, such as cumulus clouds moving past the sun, adding more variety and comfort to the light patterns experienced by the occupants of the interior space.

In one embodiment, the brightness of the light can be maintained at a desired sufficient level for office work. Thresholds can be set to cross for times when recorded daylight hours are likely to drop below this threshold. For example, thick clouds may obscure a substantial amount of daylight, causing light levels to fall below desired levels during playback of a record, and hinder work. Thresholds can be used to increase brightness, change color, or both to ensure that lighting levels do not impede work. It is also possible to further adjust the threshold to a level that induces a good feeling while remaining above an ergonomically acceptable level.

Changes in illumination levels in one embodiment can be rather subtle, often only subconsciously felt. By removing extremes, the change in light is not annoying but has a calming or relaxing effect on the person.

The Kelvin temperature is a numerical brightness that describes the color performance of light produced by a light source, and the color performance of the light source itself is expressed on the Kelvin (K) temperature scale.

In applications, the Kelvin temperature of light sources is used to classify them as warm, neutral or cool light sources. These terms do not directly refer to temperature; instead, these terms describe how the light source visually appears. Warm light sources actually have a lower color temperature (3500K or lower), producing a reddish-yellow appearance similar to natural morning light. Neutral light sources (between 3500K and 4100K) tend to have a yellowish appearance. A light source with a color temperature of 5000K is considered pure white light (full spectrum), with the light becoming bluer in color as the color temperature rises.

Warm light sources are traditionally used in applications where warm or brown-dominated environments need to impart a sense of comfort, coziness and relaxation. Cool light sources (5000K to 7000K+) provide white light similar to full daylight. In previous lighting arrangements, such white light was associated with higher productivity and fewer errors within an office environment.

An example of a lighting system 1300 is shown in block diagram form in FIG. 13 . A lighting device, such as a light emitting diode (LED) array 1310 includes multiple groups of LEDs adapted to emit light of at least two different colors. In one embodiment, the color corresponds to substantially yellow above about 3000K, and substantially white below about 7000K. In different embodiments, the actual Kelvin value can be changed to better approximate the desired color. Values above about 3000K are basically yellow with some red. They can be called warm colors. Values below 7000K are essentially white, with some blue in them, and are said to correspond to cool colors.

Although most of the description herein refers to LEDs, other light fixtures now known or later discovered capable of producing different colors may also be used. In one embodiment, by controlling the brightness of each color light, a lamp of about 5000K produces white light, which is beneficial for highway lighting. A range of about 4000K to 4500K produces slightly yellowish light and can be used to provide a soft light, useful when lighting streetscapes (the look or view of a street) that have a vintage style. The lighting can be controlled to produce a desired color and brightness to obtain different lighting conditions suitable for the design of the streets and buildings being illuminated. This provides flexible tools for setting the tone of light to match the streetscape of streets and buildings or the desired mood of a design.

Controller 1320 is operatively connected to light fixture 1310 and controls the brightness of the LED groups, also allowing selection of color ranges by increasing and decreasing the relative brightness of each of the different colors of light. In one embodiment, the controller 1320 has one or more daytime programs to replicate the color and brightness of ambient light during one or more typical or expected daylight hours. Controller 1320 may be connected to computer 1325 in one embodiment to facilitate downloading of day programs, user generated programs, and allow selection of day programs to run, or in other embodiments, over the course of a week or more Let several day programs cycle through. In some embodiments, it is desirable not to repeat the lighting of the five-day sequence within each week, but to vary from week to week to avoid monotonous repetition. Having more than five days of recording or programming, or including optional selection of programs daily or weekly, further increases the effectiveness of the lighting.

A switch 1330 may be provided to turn the light fixture 1310 on and off, just like a standard lighting system. A power source is shown at 1340 and may be connected to a grid or other desired power source.

In one embodiment, light fixture 1310 includes a socket substrate connected to the circuit board described above with respect to FIGS. 1-12 . The circuit board can support a controller 1320 that is connected to multiple circuits for controlling the LEDs to have different colors. In one embodiment, the first circuit can correspond to the control of the white LED module, and the second circuit can control the yellow LED module. Also, a third circuit can be used to drive all LED modules. By balancing between yellow and white LEDs, the controller can thus control the Kelvin color. With an additional optical sensor, the controller 1320 can control dimming as a function of daylight brightness and also provide on/off control.

FIG. 14 is a flowchart illustrating a method 1400 of receipt data to form one or more day programs. In one embodiment, data is acquired at 1410 using a Kelvin counter and a photometer to capture both the color of the light and the brightness of the light. The data can be acquired at an outdoor location over the course of a day. This data can include variations due to the changing angle of the sun in the sky, from being low during the morning, which produces warmer tones, to midday, with a commensurate higher brightness and cooler tones, to late afternoon, again. Produces warmer tones and lower brightness. The data can also include changes due to the movement of different clouds across the sun, creating some random variation to warmer periods of low brightness as clouds pass by. Data can be collected for different days to form many different programs. In one embodiment, seven such programs can be developed from different days of data collected.

In other embodiments, the program may be generated by a human or based on random timing. Different types of cloud passages can be recorded and randomly used to generate such programs and overlaid on data corresponding to typical cloudless days. In one embodiment, during playback, the cloud passing may be played back as if it were moving overhead across the room. The LED modules can be controlled individually or in groups to create the phenomenon of clouds passing over the sun and partially blocking sunlight. Clouds can appear to progress from one side of the room to the other. During a recorded day, many such cloud passages can be recorded. As noted above, if the clouds are too thick, blocking too much light, a minimum threshold for both brightness and color can be used to ensure that the program provides sufficient light for the working environment at all times. Similarly, a maximum brightness threshold can be used to guarantee that light becomes too bright during playback. In some embodiments, care may be taken to ensure that substantially clear days are recorded, as cloudy days may not provide a relaxing change in light compared to days with occasional clouds passing the sun. In further embodiments, the light can also be controlled to maintain a desired color or temperature range by providing minimum and maximum temperature thresholds. Many other methods of generating programs can also be used to generate simulated solar programs.

At 1420, the data can be converted into control signals for the controller to use in controlling the light. The control signal may include brightness for each color of light to control the overall color and overall brightness of the light for a selected period of time. In one embodiment, the selected period of time may vary from a few seconds or minutes to less than a second.

At 1430 , the control signal is loaded into the controller 1320 . A set of control signals corresponding to desired days is selected at 1440, for example, by running the signals sequentially, or by user selection, and executing the signals.

In yet another embodiment, multiple Kelvin gauges and photometers may be used to collect light over the volume formed by the volume to be illuminated. In other words, if a room of a certain area is to be illuminated by multiple light fixtures, such as LED arrays or panels, the gauges can be placed in the same pattern as the light fixtures would be arranged. Thus, the daytime program may consist of a separate program for each luminaire fixture corresponding to the data acquired at the location associated with the respective luminaire fixture. In this way, the movement of the clouds past the sun will cause each of the different light fixtures to be controlled slightly differently at the same time, creating a more realistic feeling of being outdoors.

In yet another embodiment, the sensors can collect data in real-time and the final program is provided directly to the controller to control the lighting conditions so that they follow the ongoing daylight changes. In one embodiment, the sensor may be located just outside an office or other space with windows so that the lighting in the room is controlled to follow the visual environment outside the room with as little delay as possible.

FIG. 15 is a flowchart illustrating a method 1500 of executing a program in a controller in an exemplary embodiment. At 1510 the control signal is read. At 1520, if the total brightness is below the threshold, the brightness is set to the threshold, or another value above the threshold if desired. The overall color of the light does not need to be changed unless the brightness is still too low, in which case one of the colors is already at maximum and the other color LED needs to be increased in brightness. Thresholds may be selected to ensure proper lighting as required by regulations, or as otherwise desired based on personal or ergonomic recommendations. Thresholds may be selected via computer 1325 in one embodiment, or a control may be provided in switch 1330 or some other controller, such as a remote control (represented by reference numeral 1325), which is also used as an override ( override) program to provide either a different program, or a constant intensity light on a selected color. In yet another embodiment, the high brightness threshold is set to ensure that the light brightness does not exceed a desired level. In one embodiment, the light intensity of the program may be normalized or otherwise adjusted between desired high and low levels to ensure that proper operating conditions are maintained for the duration of the day program.

At 1530, the light fixture 1310 is controlled to the color and brightness identified in the day program for the selected time period. As noted, the overall brightness is a function of the combination of light produced from each set of different colored LEDs. At 1540, after a predetermined period of time, the next set of control signals is read from the day program and executed.

FIG. 16 is a structural diagram of an array 1600 of lighting devices 1610 . Each light fixture is controlled by the controller 1620 . A master controller 1620 may be used to control each light fixture 1610, or in yet another embodiment, each light fixture 1610 has its own controller synchronized with the other controllers. In one embodiment, the controller 1620 runs a daytime program that includes individual control signals for each light fixture. Such individual control signals may be formed from data collected from the plurality of gauges described with respect to the alternative embodiment of FIG. 14 . In this way, the array of light fixtures will more accurately simulate the daytime conditions outside. In yet another embodiment, a single control signal is provided in the day program, but this signal can be staggered by the controller so that it is applied in close proximity to an event such as a cloud passing. For example, the control signal may be staggered so that it is delayed on the order of a few seconds or less between the first light fixture or group of light fixtures in the array and the last light fixture or group of light fixtures. In other embodiments, the aforementioned delays may be significantly different.

With the described lighting system embodiments, the lighting can be made to create the impression of a drifting effect, as if the clouds were actually passing over the ceiling of the office, from one light fixture to the next, causing a gradual change in the brightness of the light while the Kelvin of the light Colors vary from yellowish in the morning to white at its peak brightness in the middle of the day when natural daylight is strongest. As the day progresses to night, more yellowish colors reappear. Many small changes in the quality of light provide the stress relief effect that people in the workplace need to feel comfortable. Humans spend most of our daylight for only about a hundred years under artificial light designed to replace the sun's role and prolong our daylight. While humans have spent tens of thousands of years in the sun, genetic development still follows changes that occur in outdoor lighting conditions. Modifying indoor lighting to match or simulate such outdoor daylight conditions may be more suitable for evolved humans.

Figure 17 is a flowchart illustrating a method 1700 of controlling an array of light fixtures 1610 in accordance with a program in a controller, in an exemplary embodiment. At 1710 the control signal is read. At 1720, if the total brightness is less than the threshold, the brightness is set to the threshold, or another value above the threshold if desired. The overall color of the light does not need to be changed unless the brightness is still too low, in which case one of the colors is already at a maximum and the other color LEDs need to be increased in brightness. Thresholds may be selected to ensure proper lighting as required by regulations, or as otherwise desired based on personal or ergonomic recommendations. In one embodiment, the threshold may be selected via computer 1325, or a control may be provided in switch 1330 or other controller, such as a remote control (also indicated by reference numeral 1325), which may also be used to override the program to Either different programs are provided, or the light has a constant intensity on selected colours.

At 1730, light fixture 1610 is controlled to the color and brightness identified in the day program for the selected time period. As noted, the total brightness is a function of the combination of light produced from each set of different colored LEDs, as either registered by the sensor array or staggered between luminaire fixtures 1610 as described above. At 1740, after a predetermined period of time, the next set of control signals is read from the day program and executed.

In one embodiment, each light fixture 1610 may have independently controllable multiple colored LEDs. In a further embodiment, an array of light fixtures 410 may be used, each array of light fixtures 1610 having LEDs emitting a single color. The light fixtures can then be interspersed with different colored light fixtures 1610 and controlled so that the entire array provides light of the desired color and intensity according to the day program.

In one embodiment, a photometer may be used to measure the brightness of light emitted from the light fixture to provide a feedback signal to count small dips in brightness of other types of light fixtures or LEDs in the light fixture over the lifetime. That way, even as the LEDs age and produce less light, they still provide the same amount of light as programmed. If the LEDs fail to produce the desired brightness, an indication may be provided that one or more LEDs may need to be replaced.

FIG. 19 is a structural diagram of a lighting device 1900 , which includes a plurality of LED lighting fixtures 1910 and a transceiver 1920 . As described above with respect to Figures 1-12, the light fixture may include a circuit board with multiple sockets with LED modules (light fixture 1910), and circuitry, connected with flexible wires to provide power and control to the modules. In one embodiment, the LED module may be formed from a Nichi chip providing 100 lumens per watt, model number NS6W083B. Transceiver 1920 may be supported on a circuit board, such as a silver-plated PCB board, and may include control functions for controlling a module that may include light fixtures 1910 of different colors to provide desired lighting colors and brightness to facilitate lighting implementation street view or other purposes.

In one embodiment, each light fixture 1910 is connected to a circuit 1930 that accepts power for the light fixture and enables power to be sent to the next light fixture by bypassing a burnt or failed light fixture. In addition, circuits 1930 are connected to each other via one or more buses 1935 to send an indication that an associated light fixture, such as an LED, is inoperative. These indications are received by the transceiver 1920, which contains the logic and communication protocol to send information indicating that the light fixture has failed. The ID can be stored at 1940 for inclusion in the sent information.

In electronic form, it can be viewed on a handheld device, which can also be used to navigate to the corresponding light fixture. The list can be customized to follow an efficient path when performing maintenance.

In one embodiment, a specific light fixture within a light fixture that needs to be replaced can be identified, allowing for simple identification in the field without having to examine the light fixtures in the light fixture to try to determine which light fixture needs to be replaced. Such an attempt may involve turning on the light fixture and wearing sunglasses or other protective eyewear to view the very bright LED to determine the location of the failed LED.

FIG. 20 is a structural circuit diagram of an exemplary circuit 1930 . In one embodiment, the bus 1935 includes a power line 2010 , a ground line 2030 and a communication line 2020 . The communication line is connected to a communication module 2040, which in one embodiment contains information identifying the location of the light fixture 1910 to which the circuit 1930 is connected. The communication module 2040 is connected to the power supply and detection module 2050 which is connected to power the light fixture via lines 2060 and 2070 . The detection module disconnects the light fixture from lines 2060 and 2070 when the light fixture exhibits a short circuit so that other light fixtures in the light fixture can continue to receive power. The detection module 2050 indicates to the communication module 2040 that the light fixture has failed, either by detecting a short or open circuit, or by otherwise inappropriate power requirements of the light fixture 1910 . In another embodiment, a separate communication line can be provided to each circuit 1930 so that logic within the transceiver can identify a failure by associating one or more communication lines with the location of the failed light fixture in the light fixture array.

In one embodiment the control device 2100 has a data entry device, such as a key or a touch screen 2120, which allows the user to select the light fixture to be controlled. The GPS unit may provide location information that, when provided to the central controller, causes the central controller to display light fixtures that are close to the location of the remote control device 2100 .

Remote control device 2100 displays local light fixtures and provides an interface to allow a user to select a control program for a light fixture, or otherwise control the relative brightness of colored light fixtures to achieve a desired color corresponding to a desired street view object.

Figures 22, 23, 24 and 25 illustrate an LED lighting module 2200 having a cylindrical body portion 2210 and a compressible gasket 2215 which may be formed from rubber or other compressible material. A portion of the gasket 2215 may be formed with openings to increase the amount of compression provided when the module 2200 is inserted into a light fixture. The body portion 2210 may be formed from metal, such as aluminum or other thermally conductive material, and may have a heat sink portion 2220 formed on one end. The heat sink portion 2220 may be formed with heat sink fins 2222 or other structures to facilitate the conduction of heat away from the LEDs supported by the module 2200 at the same end.

Body portion 2200 may include a foot portion 2225 spaced from the body portion and formed at least in part from an electrically insulating material. In one embodiment, the foot 2225 is formed in an oval shape, and the contacts 2230 are located at both ends of the oval. The contact extends to a side of the foot not shown, but facing the compressible washer 2215 . When the foot 2225 is inserted into the bar of the base plate 2310 (FIG. 23) and twisted into place, it presses the washer 2215 against a portion of the bar so that the contact forms with the power contact 2310 in the bar. Good electrical connection to supply power to module 2200. Conductors 2235 can be connected to the contacts and introduced through openings in the feet back through the body portion to supply power to the LEDs. In other embodiments, an additional sealing gasket 2240 may be disposed on the body portion between the gasket 2215 and the foot 2225 , forming a weatherproof seal against the receptacle in the base plate 2310 .

The module is inserted into the socket on the bar of the base plate and then turned into position to align the contacts to a given circuit. The pressure on the contact point is created by the compression of the module's weather-sealed gasket, which pulls in an outward manner, out of the backside surface of the bar, sandwiching the bar between the feet of the module and the substrate bar assembly. A wide range of pressure is generated on the contact points inside, and reliable electrical contact is obtained through the large expansion and contraction of the lighting device in time.

Figure 24 shows a luminaire assembly 2400 showing several luminaire modules mounted on several rails of a base plate. FIG. 25 is a top view of light fixture 2400 . In one embodiment the light fixture 2400 is designed as an outdoor light fixture for outdoor lighting of large areas and can be used as a street or parking lot light, among many other outdoor applications.
