Description
Technical Field
[0001] The invention belongs to the technical field of semiconductor lighting, and in particular relates to an RGB light source structure. Background Art
[0002] RGB light source is a technology that realizes multiple color display by combining three basic color light sources: red, green and blue. Millions of colors can be generated by adjusting the brightness of red, green and blue LEDs and using the principle of additive color mixing. In addition, different light colors and brightness can be set through the controller to achieve static color, dynamic gradient or flashing effects, making RGB light sources widely used in display equipment, stage lighting, illumination and other fields.
[0003] RGB light sources will generate a lot of heat when they continue to emit light. Therefore, in most cases, external heat sinks or fans and other cooling devices are required for auxiliary heat dissipation to prevent overheating from affecting the life of the RGB light source. There are many different types of RGB light sources on the market, but most of the current RGB light sources have relatively simple structures and generally do not have a good heat dissipation structure. In actual use, they generally rely on external cooling fans and other devices for auxiliary heat dissipation. However, the use of external cooling devices such as cooling fans is usually only suitable for medium and large LED light-emitting devices. For some small and medium-sized LED light-emitting devices, or when it is inconvenient to install active heat dissipation devices, it is usually impossible to achieve rapid heat dissipation of the light-emitting devices. When a large number of densely installed RGB light sources continue to work for a long time, in the absence of auxiliary heat dissipation devices for active heat dissipation, it is easy to cause overheating inside the RGB light source, which in turn causes the failure of the RGB light source and affects its actual service life. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an RGB light source structure.

[0007] The packaging bracket is also provided with a heat dissipation structure for guiding and diffusing heat during the operation of the light-emitting module;
[0008] A negative electrode notch is also provided on one side of the rear end of the top of the packaging bracket. By providing the negative electrode notch, the negative electrode pin at the corresponding position can be determined more conveniently and quickly to facilitate accurate welding and prevent wrong welding or erroneous welding.
[0009] Furthermore, the light-emitting module includes a positive and negative functional area located at the bottom center of the packaging bracket, and an isolation dam for isolating the pin structure is provided in the positive and negative functional area. The R light-emitting chip, G light-emitting chip and B light-emitting chip are respectively installed in the positive and negative functional area, and the positive and negative pins of the R light-emitting chip, G light-emitting chip and B light-emitting chip are electrically connected to the corresponding pin structure through gold wires.
[0010] Through the above technical solution, the light-emitting module serves as the main working unit. After the positive and negative power supplies of the pin structure are connected, the R light-emitting chip, the G light-emitting chip and the B light-emitting chip can emit corresponding red light, green light and blue light according to the control program of the external IC chip.

[0011] Furthermore, the pin structure includes a first positive pin, a second positive pin and a third positive pin located at the front end of the packaging bracket and a first negative pin, a second negative pin and a third negative pin located at the rear end of the packaging bracket.
[0012] Through the above technical solution, the positive and negative pins of the pin structure are used to connect the positive and negative poles of the power supply respectively. In actual use, the corresponding positive and negative pins will be welded on the corresponding circuit board and correspond one by one to the positive and negative pins set on the circuit board. After the power is turned on, and under the integrated control of the external IC chip, the corresponding R light-emitting chip, G light-emitting chip and B light-emitting chip can be controlled to emit light independently or in combination, thereby realizing the control and adjustment of the light color.

Even without the auxiliary heat dissipation of external auxiliary heat dissipation equipment, an active heat dissipation effect is achieved, and then the heat can be dissipated outwards autonomously during the continuous operation of the RGB light source, thereby reducing the operating temperature of its core working area, thereby effectively preventing the occurrence of overheating; on the other hand, by providing an insulating layer, the bottom heat conduction plate can be prevented from interfering with the circuit connection of the light-emitting module, thereby ensuring the normal operation of the light-emitting module.

[0020] Through the above technical scheme, by setting up a mounting structure matching the structure two, it is convenient for the quick installation and fixation of the structure two, and it is also more convenient for production and assembly. After the structure two is installed and fixed on the packaging bracket, the packaging bracket and the packaging cover plate can be tightly connected by snapping, and then the lens can be installed on the support table and located on the inner side of the limit ring, and finally the packaging colloid can be used for overall packaging.

[0051] In this embodiment, a heat dissipation structure 5 is further provided in the packaging bracket 1 to guide and diffuse heat outward during the operation of the light emitting module 2 .
[0052] The present embodiment provides a configuration of the heat dissipation structure 5, specifically structure 1 51, which includes a bottom heat conducting plate 511 installed in the through hole 111, and the bottom heat conducting plate 511 is a U-shaped structure as a whole, and its two ends are respectively located in the corresponding side grooves 112, and an insulating layer 512 is attached to the top center of the bottom heat conducting plate 511.

[0056] Furthermore, in this embodiment, the middle heat conducting plate 521, the inner heat conducting ring 523 and the outer heat conducting skirt 524 are an integrated structure, which not only makes the overall structure simpler, but also facilitates production and assembly. Embodiment 3
[0057] like Figure 13-Figure 17As shown, the difference between this embodiment and the first embodiment is that a stepped positioning groove 131 is provided on the inner side of the packaging bracket 1, and a plurality of evenly distributed shallow glue injection grooves 132 are provided on the surrounding side of the stepped positioning groove 131.

[0060] The working principle of this embodiment is as follows. When in use, the positive and negative pins corresponding to the pin structure 3 can be welded to the corresponding circuit board by welding. During the welding process, it is necessary to make them correspond one-to-one with the positive and negative pins set on the circuit board. After the power is turned on, under the integrated control of the external IC chip, the corresponding R light-emitting chip 23, G light-emitting chip 24 and B light-emitting chip 25 can be controlled to emit light independently or in combination, thereby realizing the control and adjustment of the light color;
[0061] A heat dissipation structure 5 is also provided in the packaging bracket 1. During the continuous operation of the RGB light source, the heat dissipation structure 5 can use its own structure to guide and diffuse heat outwards. Even without the auxiliary heat dissipation of external auxiliary heat dissipation equipment, an active heat dissipation effect can be achieved. Therefore, the heat can be dissipated outwards autonomously during the continuous operation of the RGB light source, thereby reducing the operating temperature of its core working area, thereby avoiding overheating and ensuring the continuous and stable operation of the light-emitting module 2.
