Description

Lamp control system

The invention relates to a lamp control system, in particular to a lamp control system capable of simultaneously opening a plurality of lamps according to the induction result of the thermoelectric sensor.

A pyroelectricity sensor is an infrared detection sensor that is mainly used to detect infrared rays emitted by human body temperature to detect the presence of a human body in the environment. At present, many luminaires are equipped with a thermoelectric sensor to automatically turn the luminaire on or off according to the induction of the thermoelectric sensor. In general, a pyroelectric sensor can only sense a range of infrared heat sources. When a plurality of lamps are installed in a space, the pyroelectric sensor in the lamp far away from the infrared heat source cannot sense the infrared heat source, so that when the user enters the space, only the lamp closer to the user It will be turned on, and the luminaire farther away from the user will not be able to be turned on because its thermoelectric sensor cannot sense the user.

One of the objects of the present invention is to provide a luminaire control system that can simultaneously turn on a plurality of luminaires according to the sensing result of the thermoelectric sensor to solve the above problems.

According to an embodiment, the luminaire control system of the present invention includes N luminaires, each of which includes a light source, a drive switch, a pyroelectric sensor, a signal transmission interface, and a processing unit. The drive switch is electrically connected to the light source. The processing unit is electrically connected to the driving switch, the pyroelectric sensor and the signal transmission interface. When the pyroelectric sensor of the i-th lamp of the N lamps senses a heat source, the processing unit of the i-th lamp controls the driving switch to drive the light source to emit light, and sends a control signal through the signal transmission interface. When the processing unit of the jth lamp of the N lamps receives the control signal via the signal transmission interface, the processing unit of the jth lamp controls the driving switch to drive the light source Glowing. N is a positive integer greater than 1, and both i and j are positive integers less than or equal to N, and i is not equal to j.

In summary, when the thermoelectric sensor of any one of the plurality of lamps senses the heat source, the lamp emits a control signal to the other lamps through the signal transmission interface, in addition to being turned on and illuminated. When other lamps receive control signals via the signal transmission interface, other lamps are turned on to emit light. In other words, the present invention can simultaneously turn on a plurality of lamps according to the sensing result of the pyroelectric sensor of any one of the plurality of lamps. Thereby, when the user enters the space in which a plurality of lamps are installed, all the lamps in the space are simultaneously turned on to emit light.

Referring to FIG. 1 and FIG. 2, FIG. 1 is a schematic diagram of a lamp control system 1 according to an embodiment of the present invention, and FIG. 2 is a functional block diagram of any of the lamps 10a-10c of FIG. The luminaire control system 1 of the present invention comprises N luminaires, where N is a positive integer greater than one. As shown in Fig. 1, the luminaire control system 1 includes three luminaires 10a-10c (i.e., N=3), and three luminaires 10a-10c are disposed in a space 30. It should be noted that the number of the lamps of the present invention may be determined according to the actual application, and is not limited to the embodiment illustrated in FIG. 1 .

As shown in FIG. 2, each of the lamps 10a-10c includes a light source 100 and a drive switch. 102. A thermoelectric sensor 104, a signal transmission interface 106, a processing unit 108, a power supply 110, and an isolation coupling device 112, wherein the driving switch 102 is electrically connected to the light source 100, and the power supply 110 is electrically connected. The processing unit 108 is electrically connected to the driving switch 102, the pyroelectric sensor 104, the signal transmission interface 106, the power supply 110, and the isolation coupling device 112. The power supply 110 is used to provide the power required to drive the switch 102 and the processing unit 108 to operate.

In this embodiment, the signal transmission interface 106 can be an AC line, and the processing unit 108 is integrated with a commercial AC line modem 114. In other words, the present invention can utilize a general commercial AC line as the signal transmission interface 106 of each of the lamps 10a-10c to serially connect the signal transmission paths of all of the lamps 10a-10c. In practical applications, the light source 100 can be a light emitting diode, a fluorescent tube or other light emitting device; the driving switch 102 can be a relay or other driving device; the processing unit 108 can be a processor with signal processing function or Controller. In addition, in practical applications, the pyroelectric sensor 104 is provided with two thermoelectric induction units, and the output of the two thermoelectric induction units is reversed in series with positive and negative polarity. It should be noted that the working principles of the thermoelectric sensor 104, the isolation coupling device 112, and the mains AC data communication processor 114 are well known to those skilled in the art and will not be described herein.

In this embodiment, when the thermoelectric sensor 104 of the i-th lamp of the N lamps senses a heat source, the processing unit 108 of the i-th lamp controls the driving switch 102 to drive the light source 100 to emit light, and the signal is transmitted through the signal. The transmission interface 106 sends a control signal, where i is a positive integer less than or equal to N. Then, when the processing unit 108 of the jth lamp of the N lamps receives the control signal via the signal transmission interface 106, the processing unit 108 of the jth lamp controls the driving switch 102 to drive the light source 100 to emit light, wherein j is less than or A positive integer equal to N, and i is not equal to j.

For example, when the pyroelectric sensor 104 of the first one of the three lamps 10a-10c senses a heat source 3 (for example, a human body), the processing unit 108 of the first lamp 10a controls the driving switch. The driving light source 100 is illuminated, and a control signal is sent via the signal transmission interface 106. At this time, the control signal is transmitted to the other lamps 10b via the signal transmission interface 106, 10c. When the second and third of the three lamps 10a-10c receive the control signal via the signal transmission interface 106, the processing unit 108 of the second and third lamps 10b, 10c The drive switch 102 is controlled to drive the light source 100 to emit light. In other words, when the heat source 3 in the space 30 is sensed by the pyroelectric sensor 104 of the first lamp 10a, the light sources 100 of the three lamps 10a-10c are both turned on to emit light. Similarly, when the heat source 3 in the space 30 is sensed by the second lamp 10b or the thermoelectric sensor 104 of the third lamp 10c, the light sources 100 of the three lamps 10a-10c are also turned on to emit light. Until the heat source 3 leaves the space 30, the pyroelectric sensors 104 of the three lamps 10a-10c are not able to sense the heat source 3, and the processing units 108 of the three lamps 10a-10c are based on the sensing result of the pyroelectric sensor 104. The respective drive switches 102 are controlled to turn off the light source 100 after a predetermined time.

Please refer to FIG. 3, which is a functional block diagram of a lamp 10' according to another embodiment of the present invention. The main difference between the luminaire 10' and the above-mentioned luminaires 10a-10c is that the signal transmission interface 106' of the luminaire 10' includes an infrared communication processor 1060, an infrared ray transmitter 1062, and an infrared ray receiver 1064, wherein the infrared communication processing is performed. The device 1060 is electrically connected to the processing unit 108, the infrared emitter 1062 and the infrared receiver 1064. The present invention can replace the above-mentioned lamps 10a-10c with the lamp 10', wherein the infrared emitter 1062 is for transmitting the above control signals, and the infrared receiver 1064 is for receiving the above control signals. It should be noted that when some lamps cannot receive the control signal due to the distance or the angle relationship, other lamps receiving the control signal can be used as the relay station to forward the control signal to the lamps that have not received the control signal, thereby A luminaire that has not received a control signal will be turned on indirectly. In this embodiment, the infrared emitter 1062 and the infrared receiver 1064 are rotatably disposed on the light fixture 10' such that the user can rotate the infrared emitter 1062 and the infrared receiver 1064 to adjust the angle at which the signal is transmitted and received. The components of the same reference numerals as those shown in FIG. 2 in FIG. 3 have substantially the same principle of operation, and are not described herein again.

Therefore, the present invention can control the lamps to be turned on at the same time through a general mains AC line, or wirelessly control the lamps to be simultaneously turned on through infrared communication technology.

Please refer to FIG. 4 and FIG. 5, and FIG. 4 is a lamp according to another embodiment of the present invention. A schematic diagram of a control system 1', and FIG. 5 is a functional block diagram of any of the lamps 10a-10f of FIG. As shown in Fig. 4, the luminaire control system 1' of the present invention comprises six luminaires 10a-10f (i.e., N=6), wherein three luminaires 10a-10c are disposed in the space 30, and the other three luminaires 10d The -10f is set in the space 32.

As shown in FIG. 5, each of the lamps 10a-10f includes a setting interface 116 in addition to the components shown in FIG. 2, wherein the setting interface 116 is electrically connected to the processing unit 108 for setting a group number. . In this embodiment, the setting interface 116 can include at least one bit switch 1160, and the processing unit 108 generates a group number according to the setting of the at least one bit switch 1160. For example, the setting interface 116 can include a four-bit switch 1160, and each of the bit switches 1160 can be set to 0 or 1 by the user. Therefore, the user can set the group number of all the lamps 10a-10c in the space 30 to [0 0 0 1], and set the group number of all the lamps 10d-10f in the space 32 to [1 0 0 0]. It should be noted that the number of bit switches in the setting interface 116 can be determined according to the actual application, and is not limited to two.

After the setting is completed, each of the lamps 10a-10f has a specific group number, and the above control signal will contain the group number. In this embodiment, when the i-th luminaire of the N luminaires sends a control signal, and the group number of the jth luminaire is the same as the group number of the ith luminaire, the processing unit of the jth luminaire is receiving After the control signal is controlled, the drive switch is driven to emit light. Conversely, when the group number of the kth lamp in the N lamps is different from the group number of the i-th lamp, the processing unit of the kth lamp does not control the driving switch to drive the light source after receiving the control signal. Where k is a positive integer less than or equal to N, and k is not equal to i and j.

For example, when the pyroelectric sensor 104 of the first one of the six lamps 10a-10f senses a heat source 3 (for example, a human body), the processing unit 108 of the first lamp 10a controls the driving switch. The driving light source 100 emits light, and sends a control signal via the signal transmission interface 106, wherein the control signal includes the group number [0 0 0 1] of the first lamp 10a. At this time, the control signal is transmitted to the other lamps 10b-10f via the signal transmission interface 106. Since the control signal includes the group number [0 0 0 1], and the group number [0 0 0 1] of the 2nd and 3rd lamps 10b, 10c is The group number [0 0 0 1] of the first lamp 10a is the same, so only the processing unit 108 of the second and third lamps 10b, 10c will control the driving switch 102 to drive the light source 100 to emit light after receiving the control signal. Since the group number [1 0 0 0] of the 4th to 6th lamps 10d-10f is different from the group number [0 0 0 1] of the 1st lamp 10a, the 4th to 6th lamps are The processing unit 108 of 10d-10f does not control the driving switch 102 to drive the light source 100 to emit light after receiving the control signal. It should be noted that if the user wants the lamp 10d to emit light simultaneously with the lamps 10a-10c, it is only necessary to change the four-position switch 1160 in the setting interface 116 of the lamp 10d to [0 0 0 1].

Thereby, the user can set the same group number of the lamps in the same space or the same range according to the actual lighting demand, so that the lamps in the same space or the same range can be turned on or off at the same time.

Please refer to FIG. 6. FIG. 6 is a functional block diagram of a lamp 10" according to another embodiment of the present invention. The main difference between the lamp 10" and the lamp 10a-10f described above is that the setting interface 116 of the lamp 10" An infrared receiver is configured to receive an infrared input signal, wherein the processing unit 108 generates the group number according to the infrared input signal. In this embodiment, the user can operate an infrared remote controller 34 for each The luminaires 10a-10f input corresponding group numbers to divide the luminaires 10a-10f into different groups. The present invention can replace the luminaires 10a-10f described above with the luminaire 10". It should be noted that the components of the same reference numerals as those shown in FIG. 5 have substantially the same operation principle, and are not described herein again.

Therefore, the present invention can set the group number directly on each of the lamps through the bit switch, or wirelessly set the group number for each of the lamps through the infrared communication technology. In addition, the infrared receiver 1064 of the lamp 10' in FIG. 3 can be used as a setting interface for setting a group number in addition to receiving a control signal.

In summary, when the thermoelectric sensor of any one of the plurality of lamps senses the heat source, the lamp emits a control signal to the other lamps through the signal transmission interface, in addition to being turned on and illuminated. When other lamps receive control signals via the signal transmission interface, other lamps are turned on to emit light. In other words, the invention can be based on the thermoelectricity of any of the plurality of luminaires The sensing result of the sensor simultaneously turns on multiple lamps. Thereby, when the user enters the space in which a plurality of lamps are installed, all the lamps in the space are simultaneously turned on to emit light. In addition, the present invention can set the same group number for the lamps in the same space or the same range according to the actual lighting demand, so that the lamps in the same space or the same range can be turned on or off at the same time, and the lamps in different spaces or different ranges are Will not be affected.
