Light source assembly

Abstract

The invention relates to a light source module, which comprises at least one light source and at least one light processing element, wherein the light source comprises a light emergent part; and the light source module further comprises a transmission packing layer which fills a gap between the light emergent part and the light processing element. The light source module can reduce reflection and improve refraction when light enters the light processing element, so as to improve light utilization rate.

Description

technical field [0001] The invention relates to a light source assembly. Background technique [0002] At present, light-emitting diodes have been widely used in various fields. In practical applications, special light processing components are usually used to process the light emitted by light-emitting diodes to meet various practical needs. For example, often in the light-emitting part of light-emitting diodes Set the lens to focus the light. [0003] In this design, the light first exits from the inside of the LED to the outside of the LED, passes through the gap between the lens and the LED, and then enters the lens. Since the packaging shell and the lens of the light-emitting diode are usually composed of solid materials with a refractive index much higher than that of air, the gap between the light-emitting diode and the lens will cause the following problems: First, light is prone to occur when it exits the light-emitting diode The phenomenon of total reflection red...

AI Technical Summary

Problems solved by technology

Since the packaging shell and the lens of the light-emitting diode are usually composed of solid materials with a refractive index much higher than that of air, the gap between the light-emitting diode and the lens will cause the following problems: First, light is prone to occur when it exits the light-emitting diode The phenomenon of total reflection reduces the light emitting rate of the light-emitting diode; second, the light has strong reflection and refraction at the two interfaces of the surface of the light-emitting diode and the surface of the lens, and the reflection of light will cause waste of light and reduce the light transmittance , while refraction affects the distribution of the light field

[0004] If the light source and the light processing element are made into direct contact, the above problems can be solved theoretically. However, since the shell of the light emitting diode and the light processing element are all solid materials, the tiny gap between the contact surfaces will cause unpredictable The phenomenon of light interference makes it more difficult to control the light field
