Abstract

A light emitting diode lamp source device comprises a light emitting diode light source, and further comprises a first powder layer located on an emergent light path of the light emitting diode light source, wherein the first powder layer has scattering properties. According to the light emitting diode lamp source device, the first powder layer is arranged on the emergent light path of the light emitting diode light source, and the first powder layer has the scattering properties, so light emitted by the light emitting diode light source can be converted into emergent light in multiple directions under the scattering effect of the first powder layer, the light emitting diode lamp source device has a large light emitting angle, and light strength distribution in the multiple directions can be uniform.

Description

technical field [0001] The invention relates to a light emitting diode light source device, in particular to a light emitting diode light source device with a large light emitting angle and uniform light intensity distribution. Background technique [0002] Compared with traditional light sources, Light Emitting Diode (LED) has the advantages of light weight, small size, low pollution, long life, etc. As a new type of light source, it has been increasingly used in various fields , such as street lights, traffic lights, signal lights, spotlights and decorative lights. However, as a point light source, light-emitting diodes generally have a light-emitting angle of only 120° and uneven distribution of light intensity during application. Contents of the invention [0003] In view of this, the present invention aims to provide a light emitting diode light source device with a large light emitting angle and uniform light intensity distribution. [0004] A light emitting diode ...
