Embodiment

[0013] Example: see figure 1 In the present invention, several LED luminous bodies 2 are densely installed on the circuit board 3, and the LED luminous bodies 2 are connected in parallel.

[0014] Among them, the front of the circuit board 3 is packaged with a layer of highly transparent organic silica gel 1, and the two media of the LED luminous body packaging material and the organic silica gel 1 have destroyed the spherical light-gathering performance of the LED luminous body 2, and the astigmatism effect is good, and the brightness of the light is basically the same. At the same time, the advantages of moisture resistance and anti-aging of organic silica gel are used to fully protect the LED luminous body from being durable in the outdoor environment.

[0015] The reverse side of the circuit board 3 is bonded with a layer of silicone heat-conducting cloth / sheet 4 with silicone heat-conducting adhesive, and the outer side of the silicon-gel insulating heat-conducting cloth / ...

Abstract

The great power LED lamp with scattered light has circuit board with densely installed LED light emitters and the front side of the circuit board is packed with high transparency organic silicone gel and LED light emitter packing material to eliminate the light converging performance of the LED light emitters and generate excellent light scattering effect while not decreasing the brightness radically. The organic silicone gel which moistureproof and antiageing performance can protect the LED light emitters for endurance in outdoor environment. The back side of the circuit board has one electrically insulating and heat conducting sheet adhered with heat conducting silicone to dissipate heat of the LED light emitters. The great power LED lamp of the present invention may be used as various kinds of lamp practically.

Description

technical field [0001] The invention relates to a high-power LED lamp capable of astigmatism, in particular to an improvement on the structure of the LED lamp body and the like. Background technique [0002] At present, there is still a fatal shortcoming in various LED lamps on the market. Due to the structure of the LED lamp itself, the LED lamps used for lighting always have the disadvantage that the light cannot be scattered. Even if the straw hat-shaped LED lamp tube is used, It still has the disadvantage of poor astigmatism effect, and reduces the brightness of the lamp. [0003] Furthermore, the LED light-emitting parts must be in a working environment below 75°C to take advantage of the long life. The LED light-emitting parts themselves will be slightly hot when they are working. In order to achieve the designed brightness and increase the output power, LED light-emitting parts are often densely installed. Such Under working conditions, high temperatures above 75°C c...
