Among them, the backlight module, as a module that determines the brightness, uniformity of emitted light, color gradation and other parameters of display products, largely determines the luminous effect of display products.

[0003] Lighting up is an essential quality inspection process before the backlight module leaves the factory. Since the LCD module and the backlight module are assembled using automated equipment, the backlight module does not undergo a lighting up quality inspection process before assembly. In other words, the lighting up quality inspection process before leaving the factory is the only lighting up quality inspection process in the manufacturing process of display products, which puts a lot of pressure on quality inspectors. In addition, Figure 1 In order to inspect the backlight module from multiple angles by using the backlight lighting fixture 1', the inspector needs to constantly adjust his head for inspection; and / or, in order to relieve or reduce the soreness of his head, the inspector picks up the backlight lighting fixture holding the backlight module for inspection. The above-mentioned methods not only have low inspection efficiency, but also cause hand and neck strain to the inspector in the long run.

[0004] Based on this, it is urgent to invent a multi-angle backlight lighting fixture to solve the above-mentioned technical problems. Utility Model Content
