Stereoscopic light source component for LEDs

Abstract

The invention provides a stereoscopic light source component for LEDs. The light source component is characterized by comprising a substrate (1), an independent flexible circuit board (3) and a plurality of luminous chips (4), wherein at least one part of the substrate (1) adopts a waved structure; the flexible circuit board (3) is matched with the waved structure in shape, and attached to the surface of the waved structure; the luminous chips (4) are arranged on the substrate (1), and connected with the flexible circuit board (3). Through the arrangement of the waved structure, light rays of the LED luminous chips are less sheltered, so that the luminous effect is improved; extension parts (2) are additionally arranged to reflect the light rays emitted by the LED luminous chips, so that the luminous intensity is improved, and light-emitting angle is enlarged.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lamp, in particular to an LED three-dimensional light source assembly and a bulb thereof. Background technique [0002] With the large-scale application of LEDs, the advantages of being a new light source for emerging lighting are becoming more and more obvious, but at the same time, the price, the unidirectional luminescence of LEDs and the need for large-area heat dissipation devices for LEDs. [0003] The troubles of the following issues have increasingly become part of the obstacles to the development of LED lighting. [0004] A. Price: LED lighting is composed of four major parts: LED light source, power drive, LED cooling device and bulb structure. As the price of LED light source continues to drop, the cost of the other three parts becomes severe. [0005] B. Large cooling device [0006] Because LEDs generate a lot of heat when they emit light, in order to protect the...

AI Technical Summary

Problems solved by technology

[0006] Because LEDs generate a lot of heat when they emit light, in order to protect the stable performance of the product in the design, a large area of ​​metal must be used to assist in heat dissipation. This part of the metal increases the cost of the lamp and limits the directionality of the LED's one-way light output. It also partially blocks the lamp. totality of light

[0007] C, the light angle is limited

[0008] The light-emitting components of existing LED lamps are usually composed of a substrate and a light-emitting chip, and the shape of the substrate is a linear structure, and the light-emitting chip is arranged on the surface of the substrate. It is blocked by the substrate, resulting in poor light output from the side of the lamp
