led light source module and large angle led light

Abstract

The invention discloses an LED (light emitting diode) light source module and a large-angle LED lamp. The light source module comprises an LED substrate and a plurality of LED chips, wherein the LED substrate comprises a middle portion and blades; the blades surround the middle portion, are uniformly distributed and are bent; and the LED chips are fixedly distributed on the middle portion and the blades. The large-angle LED lamp comprises a lamp holder, a power source rubber base, a radiator, a power module and the LED light source module, wherein the power module is arranged in the power source rubber base; the radiator is hollow; a projection which is used for bearing the LED light source module is arranged in the center of the upper surface of the radiator; the shape of the projection is matched with that of the LED light source module; and the LED light source module is fastened on the projection, so that a multi-face luminous body is formed. After the LED substrate is integrally bent, connection on extra circuits is not required, production operability is improved, the manufacturing technique is simplified, and the purpose of reducing the production cost is achieved.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED light source module and a large-angle LED lamp. Background technique [0002] It is difficult for ordinary LED bulbs to achieve a large angle. Due to the shape of the bulb and the angle of the LED lamp itself, the angle basically does not exceed 150°. At the same time, when the power is increased, there is no way to solve the problem of heat dissipation. [0003] Some of the more mainstream designs are as follows: [0004] 1) Using multiple rod-shaped LEDs or multiple strip-shaped substrates to achieve a large angle, their common disadvantages are poor heat dissipation and complicated processes; they cannot achieve high power, are not easy to produce, and cannot guarantee their lifespan. [0005] 2) Set a protruding polyhedral base on the radiator, LED lamp beads are attached to three to more than six aluminum lamp panels, and then the aluminum lamp panels are attach...

AI Technical Summary

Problems solved by technology

Although the angle can be enlarged; the disadvantage is that the heat dissipation is poor and the process is complicated; the labor cost is high and the power cannot be achieved.

[0006] 3) Use reflective cups or stereo lenses for secondary light distribution to achieve large angles. The disadvantages are serious light loss, low light, and the bulb shadow problem cannot be solved. In order to achieve high luminous flux, it is difficult to dissipate heat

[0007] 4) Increase the size of the lamp type and increase the heat dissipation area, but the lamp body is too large and heavy, and it does not meet the lamp type standard and is a non-standard lamp. It is difficult to promote and is not popular in the market.
