Embodiment Construction

[0019] The following describes the utility model in further detail with reference to the drawings and specific embodiments:

[0020] see figure 1 , figure 2 , image 3 Since the present utility model relates to the innovation of the heat dissipation structure, when drawing, the bottom plate 1, that is, the circuit connection on the PCB board is not drawn.

[0021] The bottom plate 1 uses a common PCB board, which has a low cost. The bottom plate 1 has holes 5, and the number of holes 5 is set according to the brightness. Generally speaking, the brightness is controlled by the number of LED lights 3. That is to say, the number of holes 5 is correspondingly set according to the number of LED lights 3. The holes 5 can also be arranged according to different uses to diversify the shape of the light-emitting module, which can be a series of shapes such as circle, bar, rectangle or font. Preferably, the hole 5 is a round hole, and the hole diameter is larger than the outer diameter of ...

Abstract

The invention discloses an LED module provided with a radiating structure, which has low cost, simple structure and better radiating effect. The structure of the LED module comprises a base plate, and the primary technical points of the invention are that an aperture is arranged on the base plate and an LED light is put in the aperture; a thermal pad is arranged at the bottom of the LED light, and the anode and cathode of the LED light are respectively connected with welding spots on the base plate through a bus-bar, and the welding spots are respectively connected with the anode and cathode of a power supply. The thermal pad directly contacts a radiating body, and then the generated heat is transmitted to the radiating body, therefore, the better radiating effect is ensured.

Description

Technical field [0001] The invention relates to a lighting appliance, in particular to a lighting appliance of a high-power LED lamp. Background technique [0002] The LED light-emitting module is composed of a circuit board and at least one LED lamp separately arranged on the circuit board. In the high-power LED light-emitting module, the good or bad heat dissipation becomes one of the main factors that affect its performance. . [0003] From the current point of view, in order to realize the heat dissipation of high-power LED lamps, the methods are different. For example, one method is to solder the LED lamp on an aluminum-based PCB, that is, an aluminum printed circuit board, and the LED thermal pad and the aluminum substrate are welded or heat-conducted. In combination with silicone grease, the bottom surface of the aluminum substrate is directly or combined with the heat sink with thermally conductive silicone grease to achieve the purpose of heat dissipation. However, becau...
