A detailed description will be given below in conjunction with the accompanying drawings.

Example 1

The utility model provides an LED lighting device with a wireless communication function, as shown in FIG.

As shown in FIG. 2 , the integrated circuit board, the communication module and the LED light source module 40 are arranged in the lamp housing 20 . It should be noted that the LED lighting device with wireless communication function under the first embodiment does not include the outer casing 26 in FIG. 2 , but only includes the lamp housing 20 .

The lamp housing 20 is connected to the lamp cap 10 and the lamp shade 30 respectively. The lamp housing 20 is made of high thermal conductivity plastic with a thermal conductivity of 10-20 W/mk, and the lamp housing 20 is also used as a radiator. A communication module 22 having a wireless relay function is connected to a plurality of antennas 25 . Multiple antennas are arranged in the lamp housing or on the outer surface of the lamp housing in a space diversity manner, so that the antennas can effectively transmit wireless signals and improve the intensity and quality of wireless signals in the lighting area.

An antenna is pasted on the surface of the lamp housing or inside the lamp housing to transmit or receive wireless signals to the surroundings of the LED lighting equipment. The antenna transmits the received electromagnetic wave signal to the communication module with wireless relay function, and the communication module transmits the information to the Internet through the wireless router. During the communication process, the antenna can also transmit Internet data to the communication module with wireless relay function of the LED lighting equipment via the wireless router, and provide data links to the wireless terminal equipment in the lighting area of the LED lighting equipment through the communication module. When the LED lighting equipment is working, the temperature of the lamp housing is higher than that of the air, and the air near the lamp housing will be relatively dry, which is beneficial to protect the antenna from moisture and prolong the service life of the antenna.

Preferably, there are two antennas, which are arranged at two different positions on the outer surface of the lamp housing. Such antenna distribution is beneficial to the room where the LED lighting equipment is located to be fully covered by wireless signals without dead ends. Optimally, the two antennas are symmetrically distributed on the outer surface of the lamp housing 20 near the end of the LED light source module in a space diversity manner. Such antenna distribution makes the wireless signal coverage wider and the signal better.

LED lighting equipment must go through a high-voltage test before leaving the factory. The purpose is to test the safety of the product and ensure that the products produced will not cause human injury accidents when customers use them. Therefore, the antenna arranged on the lamp housing also needs to undergo a high voltage test. The antenna in this embodiment is preferably a ceramic antenna.

The thermal inertia of the ceramic antenna is small, stable in high temperature environment, small power attenuation, strong voltage shock resistance, long service life, and high mechanical strength. Therefore, when the LED lighting equipment is subjected to a high-voltage test, the ceramic antenna can withstand the impact of high voltage and is not easily damaged. At the same time, the coefficient of thermal expansion of ceramics is 3.5-4.0, which is relatively low, and will not deform on the surface of the lamp housing.

According to a preferred embodiment, the antenna can also be a printed antenna or an LDS antenna. The printed antenna uses the surface of the lamp housing as a substrate and is printed on the surface of the lamp housing. The printed antenna is small in size and the manufacturing process is relatively simple, which meets the needs of modern equipment miniaturization. LDS antenna technology is Laser-Direct-structuring technology (Laser-Direct-structuring), using the computer to control the movement of the laser according to the trajectory of the conductive pattern, projecting the laser onto the molded three-dimensional plastic device, within a few seconds, Activate the circuit pattern. The LDS antenna has stable performance, saves space, and has high signal quality, which can reduce the mass and volume of LED lighting equipment.

As shown in FIG. 3 , the LED light source module 40 includes a light source base 24 , a heat-conducting substrate 42 and at least one LED chip covered with a fluorescent material, and a heat-conducting silicone grease is pasted or coated between the light source base 24 and the heat-conducting substrate 42 Layer 43. The lampshade 30 is pasted between the light source base 24 and the lamp housing 20 .

According to a preferred embodiment, the lamp housing 20 and the light source base 24 are fixed by buckles. Alternatively, threads are provided on the metal inner wall of the lamp housing 20 . Then, the LED light source base 24 and the metal inner wall of the lamp housing are fixed through screw connection, and at the same time, a heat-conducting silicone grease layer is added between the light source base 24 and the metal inner wall of the lamp housing to promote heat conduction.

The circuit module arrangement of the LED lighting device is shown in FIG. 5 , and the integrated circuit board includes a power supply module 23 , a light source driving module 21 and a control module 28 . The input end of the power supply module 23 is connected with the mains, and converts the high-voltage AC power into a low-voltage DC power. The output terminal of the power supply module 23 is connected with the input terminals of the light source driving module 21 , the control module 28 and the communication module 22 . The output end of the light source driving module 21 is connected to the input end of the LED light source module 40 and the control module 28 respectively, and accepts the dimming control of the control module. The output terminal of the communication module 22 is connected with the input terminal of the control module 28 to realize bidirectional transmission of communication data. The communication module 22 is connected to the antenna 25 through an antenna extension material such as plastic or glass fiber. The antenna is a 2*2 antenna with a wireless relay function. M*N, the number M before the multiplication sign is the number of transmitting antennas, and the number N after the multiplication sign is the number of receiving antennas.

The communication module 22 has a wireless connection function and can be connected with a wireless router. Users can use mobile phones, tablet computers, computers and other devices to connect to wireless routers through wireless signals, and then connect to this lighting equipment to control the lighting equipment's functions such as turning on, turning off, and dimming. Moreover, within the coverage area of the wireless signal of the lighting equipment, the user connects with the wireless router through the relay network function to expand the coverage area of the wireless local area network.

Example 2

This embodiment only describes the part of the implementation manner that is different from that of the embodiment 1, and the part of the implementation manner that is the same will not be described again. Compared with the embodiment 1, the embodiment 2 adds an outer casing 26 outside the lamp housing.

The outer shell structure shown in Figure 2. On the outer side of the lamp housing 20 close to the end of the LED light source module 40 , an outer housing 26 with a longitudinal dimension significantly smaller than the lamp housing is sheathed to surround the lamp housing. There is enough space between the outer casing 26 and the lamp housing 20 to accommodate the antenna and allow air convection at both ends of the outer casing 26, so that the antenna disposed on the outer surface of the lamp housing is always in a dry environment.

When the LED lighting equipment is working, the temperature of the lamp housing is higher than the indoor temperature. There is a temperature difference between the air around the lamp housing and the indoor temperature, so that air convection occurs. Air convection will reduce the temperature of the lamp housing and improve the heat dissipation capacity of the lamp housing.

The outer shell 26 is obviously smaller than the longitudinal dimension of the lamp housing. The purpose of this design is to prevent the longitudinal dimension of the outer shell from being too long, which will increase the thermal resistance of the lighting equipment and affect the heat dissipation effect of the equipment. Although the space between the outer shell 26 and the lamp housing 20 will promote convection at both ends of the outer shell, if the outer shell and the lamp housing have the same longitudinal dimension, the air flow path will be lengthened. An excessively long flow path will undoubtedly slow down the flow speed of the air and reduce the effect of heat dissipation. Therefore, a short outer shell is the best choice, which not only allows the air to flow at the fastest speed but also protects the antenna. The outer casing is arranged at one end close to the LED light source module 40, and the antenna will be well insulated and protected without short circuit with the lamp holder.

Referring to Figure 1 or Figure 4, the outer shell 26 is integrally formed on the outside of the lamp housing 20, and a plurality of connecting bones 53 integrally formed with the lamp housing and the outer shell are provided between the lamp housing 20 and the outer shell. Moreover, the plurality of connecting ribs longitudinally partition the space between the lamp housing 20 and the outer casing 26 into a plurality of cavities 29 with openings at both ends and capable of accommodating antennas.

The inner wall of the lamp housing 20 is connected with high thermal conductivity materials such as aluminum, copper or graphite, which is good for heat dissipation. The high thermal conductivity material guides the heat generated by the LED light source and electronic components to the lamp housing in time, preventing excessive heat from flowing to the communication module 22, the light source driving module 21 and the control module 28 inside the lamp housing.

In this embodiment, the way of injection molding or pouring is chosen to connect the lamp housing 20, the outer shell 26 and high thermal conductivity materials such as aluminum and copper. First, aluminum, copper and other high thermal conductivity metal materials are cast or machined into the metal skeleton structure of the lamp housing, and then the metal skeleton structure is placed in a mold, and then injected or cast with high thermal conductivity plastic. After the high thermal conductivity plastic is solidified, the lamp housing and the outer shell in which the high thermal conductivity plastic and the outer surface of the metal frame are seamlessly and tightly combined are formed. High thermal conductivity plastics dissipate heat evenly, which can avoid hot spots and reduce deformation of parts caused by high temperature, thereby improving mechanical properties such as strength and stiffness. High thermal conductivity plastic is light in weight, only 50%-60% of aluminum, which can reduce the mass of devices with the same volume. This method reduces the thermal resistance between the two interfaces of the high thermal conductivity plastic and the high thermal conductivity metal material, ensuring smooth heat conduction.

According to a preferred embodiment, high thermal conductivity graphite with heat conduction directionality can also be used as the heat conduction layer 27 to connect the metal frame of the lamp housing with the LED light source base and the heat generating parts of the electronic components. The transverse thermal conductivity of high thermal conductivity graphite is 1000-1500W/mk, and the longitudinal thermal conductivity is 20-30W/mk, which has the characteristics of lateral heat conduction and directional heat conduction. The use of high thermal conductivity graphite can guide the heat inside the lamp housing to the lamp housing in time and dissipate it to the outside. This method avoids the problem of data loss of the communication module caused by the reduction in efficiency or damage of the electronic components in the lamp housing due to excessive temperature.

Example 3

The difference between Embodiment 3 and Embodiment 2 is that, as shown in FIG. 6 or FIG. 7 , the outer casing 26 is in the shape of a detachable ring-shaped cover. The size of the outer casing of the ring-shaped cover structure is sufficient to surround multiple antennas arranged on the surface of the lamp housing. Moreover, the outer shell is provided with a plurality of through holes for forming air convection between the outer shell and the lamp housing to promote the air flow between the outer shell 26 and the lamp housing 20 and speed up the heat dissipation of the lamp housing. The outer casing 26 is detachably sleeved on the outside of the lamp housing 20 in a threaded connection or snap connection manner.

Corresponding threads are respectively provided on the outer shell 26 and the lamp housing 20 , and the outer shell 26 and the lamp housing 20 are sheathed together in a detachable manner. Alternatively, bayonets and buckles are respectively provided on the outer shell 26 and the lamp housing 20, and the outer shell 26 and the lamp housing 20 are fixed together through the buckles. When the antenna needs to be replaced, the outer shell can be mechanically disassembled from the outside of the lamp housing.

The outer casing 26 includes a horizontal section and a vertical section connected to the horizontal section; wherein, the horizontal section is provided with a plurality of through holes, and the inner surface of the horizontal section that can be in contact with the surface of the lamp housing 20 is provided with threads or buckles structure.

In this embodiment, the vertical section connected with the horizontal section has two preferred implementations:

According to a preferred embodiment shown in Fig. 7, the side of the vertical section opposite to the horizontal section is provided with a plurality of through holes, and the positions of the through holes provided on the vertical section and the through holes provided on the horizontal section correspond to each other , and have matching shapes and sizes. The inner surface of the vertical section that can be in contact with the surface of the lamp housing is provided with a screw thread or a buckle structure.

According to another preferred embodiment shown in FIG. 6 , the vertical section is arranged in such a way that it does not contact the lamp housing. That is, a certain gap is formed with the outer surface of the lamp housing and kept suspended.

The outer casing structure of the third embodiment also protects the antenna while promoting the flow of air and speeding up the heat dissipation of the lamp housing. Moreover, the surface of the lamp housing is kept dry for a long time due to temperature, which can prolong the life of the antenna.

When there are two antennas, the two antennas are distributed in different cavities between the outer casing and the lamp housing in a space diversity manner, and simultaneously transmit and receive wireless signals. When there are multiple antennas, the multiple antennas are arranged in multiple cavities in different directions and positions in a space diversity manner, and transmit and receive signals in different directions. The occasion where the LED lighting equipment is located has achieved full coverage of the wireless signal, and the quality of the signal has been enhanced.

When the LED lamp is installed on the lamp holder, the lampshade is upward and the lamp head is downward, and the lamp holder is at a height of 1m~2m indoors, the setting of multiple antennas can well make up for the fact that one antenna cannot cover the entire range. Defects, ensure that the wireless signal in the indoor user area where the LED lights are placed has no dead-spot coverage. In addition, the outer layer of the antenna in the cavity is covered with a coating that does not shield electromagnetic signals. Coating materials include silicone resins, organic fluororesins, silicone rubbers and combinations thereof. The coating can not only protect the antenna, isolate the antenna from water vapor in the air, but also insulate the antenna so that the signal of the antenna will not be interfered.

Example 4

The difference between the fourth embodiment and the previous embodiments is that the antenna is arranged inside the lamp housing.

When the number of antennas is two or more, the antennas are distributed in the center of the LED light source module 40 or between the LED chips in a symmetrical array. Preferably, there is one antenna, which is fixed at the center of the LED light source module 40 . The height of the antenna is not greater than 2cm to avoid blocking the light. The antenna 25 is externally coated with a film/coating. The film/coating can reflect visible light with a wavelength of 390nm to 780nm, and can transmit electromagnetic waves with a wavelength of 1cm to 100cm. When the LED light is installed on the ceiling, the antenna signal can cover the indoor user Internet access area. Likewise, the LED light source module 40 is located inside the lampshade 30 . The lampshade isolates the humid air from the antenna, preventing the antenna from being damaged by moist water vapor.

Preferably, at least one antenna 25 is evenly distributed among the plurality of LED chips 41 provided on the LED light source module in a manner that does not affect the light emitted by the LED light source module 40 , not shown in the figure.

Preferably, the antenna is arranged around the LED light source module 40 in the form of a circular reflector. The surface of the antenna is selectively coated with a film/coating capable of reflecting visible light and transmitting electromagnetic waves, so that the antenna can reflect light emitted by the LED light source module 40 and emit or receive electromagnetic waves. . A lampshade 30 made of transparent material is arranged outside the LED light source module 40 , and both the antenna and the LED light source are inside the lampshade 30 . The transparent material can be plexiglass, polycarbonate, transparent PP and other materials. The antenna in the form of a circular reflector combines the functions of reflection and signal transmission, which saves the cost of LED lighting equipment and also reduces the volume and quality of the lighting, which is in line with the trend of miniaturization in the field of LED lighting. Moreover, the antenna built in the lampshade can avoid the influence of moisture and water vapor in the air, prolonging the service life of the antenna. The ring-shaped reflector antenna is a metal antenna, which will not form a short circuit with the lamp head. When the LED device is subjected to a high voltage test, it can pass the test smoothly.

Metal with geometric or simulated shapes can beautify and decorate LED lighting equipment while acting as an antenna. For example, the logo of the production company is set on the surface of the lamp housing as an antenna, which enhances the recognition of the public. Alternatively, using a plurality of butterfly-shaped, leaf-shaped, moon-shaped metals and other simulated graphics as the antenna decorative lighting equipment will make the LED lighting equipment more beautiful and elegant, and more in line with people's aesthetic needs for lamps.
