Embodiment Construction
[0013] see figure 1 , which is a schematic structural view of the LED light source module 1 according to the first embodiment of the present invention. The LED light source module 1 includes a first optical element 10, an LED light source 20 disposed in the first optical element 10, a second optical element 30 disposed on the forward light path of the LED light source 20, and a second optical element 30 disposed in the first optical element 10. A diffusion plate 40 above the two optical elements 30 .
[0014] The first optical element 10 is roughly in the shape of a spherical crown, and a through groove 11 is arranged in the middle thereof. The through groove 11 runs through the middle of the first optical element 10 . The first optical element 10 includes a first reflective surface 13 , a second reflective surface 12 and a connecting surface 14 connecting the second reflective surface 12 and the first reflective surface 13 . In this embodiment, the first reflective surface...

The invention discloses a light-emitting diode light source module which comprises a first optical element, a light-emitting diode light source arranged in the first optical element, and a second optical element arranged on a forward light emitting path of the light-emitting diode light source, wherein the first optical element is provided with a through groove; the light-emitting diode light source is arranged in the through groove; the first optical element is provided with a first reflecting surface surrounding the through groove, a second reflecting surface towards the second optical element, and a connecting surface connected with the first reflecting surface and the second reflecting surface; the second optical element is provided with a reflecting surface over against the light-emitting diode light source; and light rays emitted to the reflecting surface of the second optical element are reflected to the first reflecting surface and the second reflecting surface of the first optical element.
Description
technical field [0001] The invention relates to a light source module, in particular to a light emitting diode light source module. Background technique [0002] Compared with traditional light sources, light emitting diodes (Light Emitting Diode, LED) have 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 in various fields. [0003] A common light source module includes a number of light emitting diode light sources arranged in an array and a light-transmitting optical element covering each light emitting diode light source. In order to make the light emitted by the light emitting diode light source form a surface light source, a diffuser is usually arranged above the optical element plate. In order to obtain a larger and uniform diffused light distribution area, there is a larger distance between the LED light source and the diffuser plate to obtain a longer light mixing distance, so...
