However, with a single lens, in some applications where a large number of LEDs are used, the cost will increase linearly. At the same time, since each lens needs to be aligned with the LED and pasted on the specified position on the light board, the cost of packaging will be greatly increased. required time

Abstract
The invention discloses a light source assembly. The light source assembly comprises a strip-shaped lens and a plurality of light-emitting elements which are adjacent to the strip-shaped lens and are arranged in the length direction of the strip-shaped lens. Light rays emitted by all the light-emitting elements are emitted after passing through the strip-shaped lens. The strip-shaped lens at least comprises an in-light surface and an out-light surface. The in-light surface at least comprises a first secondary in-light surface. The out-light surface at least comprises a first secondary out-light surface. The first secondary in-light surface is an inwards-concave hook surface which is in cambered surface transition. The first secondary out-light surface is an outwards-convex hook surface which is in cambered surface transition. The invention further discloses the strip-shaped lens. In this way, the assembling efficiency of the light source assembly can be improved, and light of the light source assembly can be emitted evenly.
Description
technical field [0001] The invention relates to the field of light source technology, in particular to a light source component and a strip lens thereof. Background technique [0002] Traditional LED (Light Emitting Diode, light-emitting diode) lenses are mostly monomers, that is, one lens corresponds to one LED, and the light emitting angle of the LED is changed through refraction and reflection. However, with a single lens, in some applications where a large number of LEDs are used, the cost will increase linearly. At the same time, since each lens needs to be aligned with the LED and pasted on the specified position on the light board, the cost of packaging will be greatly increased. required time. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a light source assembly and its strip lens, which can improve the assembly efficiency of the light source assembly and make the light output of the light source ...
