Problems solved by technology

However, because the light type of the LED is circular, and its light intensity gradually decreases from the center to the edge, the LED tube is not a linear light source that produces uniform light, but forms multiple gathered apertures, resulting in overall lighting. Uneven and soft
In order to solve such problems, ordinary LED lamps need to use a large number of LEDs to be closely arranged, but this will increase the cost

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] see figure 1 , figure 2 as well as image 3 A light source module 100 provided by an embodiment of the present invention includes a lens 10 and a light emitting diode 20 disposed in the lens 10 .

[0018] The lens 10 includes a light incident surface 11 , a light exit surface 12 , a bottom surface 13 , two first side surfaces 14 and two second side surfaces 15 . The bottom surface 13 is a rectangular plane, the two parallel long sides of the rectangular plane are arranged along the first direction X, and the two parallel short sides of the rectangular plane are arranged along the second direction Y perpendicular to the first direction X.

[0019] The light incident surface 11 is a curved surface, which is formed by indenting from the center of the bottom surface 13 toward the inside of the lens 10 . The light incident surface 11 surrounds a groove...

Abstract

The invention relates to a lens, and the lens is used for regulating light rays emitted by a luminescent diode. The lens comprises an in-light surface, an out-light surface and a bottom surface, wherein the in-light surface is sunken to the inner part of the lens from the bottom surface; the out-light surface is positioned above the in-light surface and comprises a concave surface and convex surfaces positioned on both sides of the concave surface; the out-light surface is changed in an undulate manner in a first direction, and is unchanged in a second direction which is perpendicular to the first direction; after being regulated by the lens, light types generated by the luminescent diode are lengthened in the first direction. The invention also provides a light source module using the lens.

Description

technical field [0001] The invention relates to a lens and a light source module using the lens. Background technique [0002] Compared with traditional light sources, Light Emitting Diode (LED) has the advantages of light weight, small size, low pollution, and long life. As a new type of light source, it has been more and more widely used. For example, LED light tubes are one of them. [0003] The traditional fluorescent tube is a uniform and soft linear divergent light source. When using LED as the light source of the tube, because the LED is an approximate point light source, the most common method is to arrange several LEDs linearly on the substrate to form a light bar. , and then add a lampshade to form a lamp tube. However, because the light type of the LED is circular, and its light intensity gradually decreases from the center to the edge, the LED tube is not a linear light source that produces uniform light, but forms multiple gathered apertures, resulting in over...
