Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and specifically
Implementation method is described in further detail to the utility model.
With reference to Fig. 1,2,3,4,5, the utility model embodiment provides a kind of LED light source fixing device, including one square
Body 1.
The front of square body 1 is conformed with 2, and projection 2 is a quarter spherical structure；
The center of square body 1 is provided with light hole 3, and light hole 3 is frustum cone structure, the bottom of the upper surface more than round platform of round platform
Face；Being dimensioned to for the bottom surface of truncated cone-shaped is bigger than LED light source light-emitting area size 1 millimeter, facilitates the loading of substrate.
