Problems solved by technology

Therefore, the coverage area of ​​the reflection sheet 300 becomes smaller
Or, in some cases, since the light emitting diode 200 is electrically connected to the circuit board 100 by soldering the welding pin 250 of the light emitting diode 200 with the solder 400; This causes poor application of the reflective sheet 300, so the opening 350 of the reflective sheet 300 must be enlarged to avoid the welding position, so the coverage area of ​​the reflective sheet 300 will also become smaller

Embodiment Construction

[0045] Please refer to FIG. 2 , which shows a reflective sheet 700 that can be used in the light source group of the present invention. In actual use, the reflective sheet 700 has a plurality of holes 750 , however, for simplicity, only the reflective sheet 700 with one hole 750 is shown in this figure. There is at least one cutting line 760 extending from the hole 750 around the hole 750 . In FIG. 2 , the perimeter of the hole 750 has four cutting lines 760 each extending from the perimeter of the hole 750 . Certainly, the cutting line 760 may be a line extending from the center point of the hole 750 , or may be a cutting line extending from the periphery of the hole 750 but with an unspecified direction depending on the requirements of the actual manufacturing process. As for the number of cutting lines 760 , when the hole 750 is a quadrangle, the design of four symmetrical cutting lines 760 located at the four corners of the quadrangle is relatively simple. In the case th...

Abstract

The invention discloses a light source group, which comprises the following parts: circuit board, multiple points light sources on the circuit board, reflector plate with multiple first openings, wherein the reflector plate is set on the circuit plate; each first opening corresponds to the point light source and each periphery of first opening contains an extended cutting line to the opening; The oblique angle of reflector plate around the first opening periphery and circuit board is ranged from 0 to 90 deg.

Description

technical field [0001] The invention relates to a light source group, in particular to a light source group using light emitting diodes as light sources. Background technique [0002] Nowadays, liquid crystal display has been widely used in various information display devices. Its main structure can be divided into two parts: panel module and backlight module. The panel module roughly includes glass substrate, liquid crystal layer, alignment film, color filter, polarizer, driver IC and other components; the backlight module mainly includes light source, light guide plate, prism sheet, diffuser plate and reflector, etc., and the panel module light source is provided by the backlight module to achieve the purpose of information display. The overall performance of LCD products is affected by the interaction of all internal components, among which the backlight module plays an important role in screen brightness, uniformity, contrast and viewing angle. [0003] Backlight module...
