Light guide and condensation structure for surface-mounted LED

Abstract

The invention belongs to the technical field of LED light source application, discloses a light guide and condensation structure for a surface-mounted LED and aims to solve the problems of large design area and low machining and production efficiency. The light guide and condensation structure comprises a body; the body is in the shape of a prismoid; a concave scattering spherical surface is formed in the top surface of the prismoid; the scattering spherical surface is a semispherical surface; the interior of the body is of a solid structure and is fully transparent; the outer surface of the peripheral side of the body is a total-reflection surface; and the bottom surface of the body is a light-emitting surface. According to the technical schemes, emitted light of the surface-mounted LED is focused, and therefore, the surface-mounted LED can give full play to the characteristics of small area, convenience in flexible design, rapid production and machining and the like in an actual production and use process.

Description

technical field [0001] The invention relates to the technical field of LED light source application, more specifically, it relates to a light guiding and concentrating structure for patch LED light-emitting diodes. Background technique [0002] LED, Chinese name: light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of the LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. LED light-emitting diodes have long service life and low energy consumption. , low price and other characteristics, it is widely used in industry and life. [0003] There are usually two forms of LED light-emitting diodes on the market, but the two forms of light-emitting diodes have different advantages ...

AI Technical Summary

Problems solved by technology

One is the self-contained light guide column, and the light can be focused in a certain area, but due to the long soldering pins of the components, SMT manual cutting and soldering are required during installation, which brings disadvantages to mass production man-hours and universal design PCB design; One is a patch-shaped light-emitting diode. Although it can be quickly welded and applied in a large area, it cannot be concentrated in a certain area for display due to the divergence of the emitted light source, and it is difficult to be independently applied to the device.

[0004] Because the existing two forms of LED light-emitting diodes have their own disadvantages in the use process, the LED with its own light guide column has the problem of manual cutting and welding when installing, and the patch-shaped LED also has light source divergence, which cannot be concentrated on a certain one. area display problem

Therefore, the LED in the prior art has the disadvantages of large design area and slow processing and production efficiency.
