Problems solved by technology
However, in the application of the existing LED backlight, the backlight components (that is, the LED light source, the light guide plate, and the optical film) are often placed in the electrical appliance separately, and the LED light source is glued in the electrical appliance. The problem is that after long-term use or external vibration, the LED light source will fall off and affect the use of the LCD display. Moreover, this installation method is manually operated during installation or maintenance, and it is easy to damage the LED light source. Light source or optical film, so there is an urgent need for an LED backlight protection device that can be easily disassembled and installed and has a protective function

The invention discloses an LED backlight source protection device convenient to disassemble and assemble, wherein the movable cavity and the cavity are formed in the rack, and openings of the movablecavity and the cavity are forward. A movable device is arranged in the movable cavity; wherein a power cavity is formed in the rack; a power device is arranged in the power cavity; a control cavity isformed in the rack. A control device is arranged in the control cavity; the device is simple in structure, simple and convenient use, when a worker installs the backlight source, the backlight sourcecan be installed; more simple and efficient, the protection on the backlight source assembly is improved; the LED lamp source is placed through the movable plate which is movably arranged; the problem of manual adhesion when the LED lamp source is placed traditionally is solved; the problem that the LED lamp source is prone to falling off and being damaged due to the fact that the LED lamp sourceis prone to falling off due to the fact that the LED lamp source is prone to falling off due to the fact that the LED lamp source is prone to falling off is solved. Meanwhile, the optical film is automatically assembled and disassembled through mechanical transmission control and prevented from being scratched during manual operation, and the problem that the LED lamp source is difficult to dissipate heat is solved.
Description
technical field [0001] The invention relates to the technical field of LED backlight sources, in particular to an LED backlight protection device that is easy to assemble and disassemble. Background technique [0002] The backlight is a light source located behind the liquid crystal display, and its luminous effect will directly affect the visual effect of the liquid crystal display module. According to different incident modes of the light source, the backlight structure can be divided into a direct-type backlight structure and a side-type backlight structure. Among them, the side-in type backlight structure is to install the backlight LED light bar on the edge of the back panel behind the liquid crystal panel, and the light emitted by the LED light bar enters the light guide plate from the light incident surface on one side of the light guide plate, and after reflection and diffusion It emits from the light-emitting surface of the light guide plate, and then passes throug...
