[0003] The existing mixed color fantasy backlight structure generates a large amount of heat during use, and the generated heat cannot be quickly dissipated, so that the accumulation of heat affects the service life of the mixed color fantasy backlight structure, thereby causing the mixed color fantasy backlight structure to be easily damaged.

[0004] To solve the above defects, the anti-deformation large-size direct type light bar backlight with publication number CN212901095U is made of aluminum alloy, which improves the heat conduction of the backlight body and reduces the heat accumulation during the operation of the light bar. A plurality of heat dissipation holes are fixedly arranged on the upper surface of the rectangular frame body, so that the temperature generated by the light bar during operation can be well dissipated to the outside of the backlight, thereby improving the working efficiency of the backlight body.

[0005] In the actual use of the above device, although the use of the heat dissipation hole improves the heat dissipation effect, the size of the heat dissipation hole is small, which causes the heat to be unable to exchange with the outside world in time, thereby causing the heat to be squeezed, and thus the heat dissipation effect is poor.
