The invention discloses a fixing structure of a reflector plate in an LED backlight module. The fixing structure comprises the reflector plate and an LED lamp assembly. The LED lamp assembly comprises a PCB and a plurality of LED lamps connected to the PCB, and a first gap exists between a lampshade of each LED lamp and the PCB; a plurality of through holes are formed in the reflector plate and distributed corresponding to the LED lamps on the LED lamp assembly in a one-to-one mode; at least one of the through holes is an irregularly-shaped hole, and the rest are circular holes; each irregularly-shaped hole is composed of each circular hole and the edge extending into each hole of each circular hole; the LED lamps of the LED lamp assembly are arranged in corresponding through holes of the reflector plate respectively according to corresponding positions in a sleeved mode, and the edge of each irregularly-shaped hole is elastically clamped into each first gap between the lampshade of each corresponding LED lamp and the PCB. The fixing structure can ensure that a large face of a reflection face is smoothly fixed, and a cavity of the backlight module can have good luminous efficiency.
Description
technical field [0001] The invention relates to the field of televisions, in particular to a fixing structure for a reflection sheet in an LED backlight module. Background technique [0002] With the competition in the TV industry becoming more and more fierce, and the country's requirements for TV energy saving are getting higher and higher, cold cathode luminescent direct-lit LCD TVs (CCFL) have been gradually eliminated by the market, and replaced by medium and high-power LEDs. Direct-lit LCD TVs with light sources are hereinafter referred to as direct-lit LCD TVs. [0003] There is a reflector in the cavity of the backlight module of the direct-lit LED LCD TV, which is used to reflect the light source during the propagation of the LED light, so that the utilization rate of the LED light source can be maximized. In the cavity of the backlight module, the large reflective surface of the reflective sheet must be relatively flat, and the positioning of the reflective surfac...
