Title:
REFLECTOR AND BACKLIGHT HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2022/077769
Kind Code:
A1
Abstract:
The present application provides a reflector (1) and a backlight having same (1). The reflector (1) is provided with special-shaped installation holes (10); the special-shaped installation holes (10) each comprises first and second included angles that are opposite; the two edges forming the first included angle are a first upper edge (101) and a second upper edge (102), respectively; the two edges forming the second included angle are a first lower edge (103) and a second lower edge (104), respectively; each special-shaped installation hole also comprises a first arcual edge (105) and a second arcual edge (106) that are opposite; and each special-shaped installation hole (10) further comprises a first limiting edge (107), a second limiting edge (108), a third limiting edge (111), and a fourth limiting edge (112). The first upper edge (101), the second upper edge (102), the first lower edge (103), and the second lower edge (104) are spaced away from the center relative to the first limiting edge (107), the second limiting edge (108), the third limiting edge (111), and the fourth limiting edge (112), such that when a PCB board and the reflector are dislocated, there is still gaps between lens weld legs (31) and side edges of the special-shaped installation hole (10), so as to prevent cutting lens weld legs (31) when the reflector (1) expands, thereby reducing the probability of a lens (3) falling off from the PCB board, and improving fault tolerance effect of the special-shaped installation holes (10).
