Abstract

The invention provides a light-emitting diode lamp source device. The light-emitting diode lamp source device comprises a circuit board and a plurality of light-emitting diode light sources which are arranged on the circuit board and are electrically connected with the circuit board; the light-emitting diode light sources are symmetrically arranged on the circuit board; the distance between each two adjacent light-emitting diode light sources is gradually reduced in the direction which is far away from the central position of the circuit board.

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 uniform luminance. Background technique [0002] As a high-efficiency light source, light-emitting diodes have many characteristics such as environmental protection, power saving, and long life, and have been widely used in various fields. The light emitting diode light source device is generally composed of a plurality of light emitting diodes. The light emitting diode has the characteristics of a point light source, so when the plurality of light emitting diodes are arranged on the circuit board, the light intensity in the middle area of ​​the circuit board will be greater than the light intensity in the surrounding area. Therefore, the brightness of the light emitted by the light emitting diode light source device is not uniform. Contents of the invention [0003] In view of this, the present invention aims to pro...
