[0002] In practice, in the led liquid crystal test light box, the led light source is generally used as the light source. At present, the led test light box is getting bigger and bigger, and the surface luminance value is getting higher and higher, which directly leads to the higher and higher power of the light box. The led lamp beads in the light box The amount will be a lot, the larger the area of the light box is, the greater the influence of the wire loss on a single led, resulting in insufficient uniformity of illuminance on the surface of the light box, affecting the visual effect and insufficient testing accuracy of the test equipment. existing problems

Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] Figure 1 to Figure 4 A LED test light box according to an embodiment of the present invention is schematically shown. As shown in the figure, an LED test light box includes a box body 1, a lamp board 2, an LED lamp bead 3 and a power supply line 4. There are multiple LED lamp beads 3, and multiple lamp boards 2. The lamp board 2 A plurality of LED lamp beads 3 are arranged on the top, and all the LED lamp beads 3 are evenly distributed in the box body 1, and the power supply 6 is used to supply power to multiple lamp panels 2 and the LED lamp beads 3 on them, and the power supply line 4 is used to connect the power supply 6 and The lamp board 2 and any power supply line 4 used to connect the lamp board 2 and the power supply 6 have the same length.
[0029] Because for each power supply line 4, if the length is longer, the voltage loss will be great...

The invention discloses an LED test lamp box. The LED test lamp box comprises a box body, a plurality of lamp panels, a plurality of LED lamp beads and power lines. The LED lamp beads are arranged onthe lamp panels. All the LED lamp beads are uniformly distributed in the box body. A power source is used for supplying power to the lamp panels and the LED lamp beads on the lamp panels. The power lines are used for connecting the power source with the lamp panels. The lengths of all the power lines used for connecting the power source with the lamp panels are equal. The LED test lamp box has thebeneficial effects that the lengths of all the power lines used for connecting the power source with the lamp panels are set to be equal; thus, it can be ensured that voltage losses of all the powerlines are identical, input voltages finally distributed to all the lamp panels are all basically identical, and the luminance of the LED lamp beads on each lamp panel is all basically identical, and the overall brightness is more uniform. Meanwhile, the invention further provides a manufacturing method of the LED test lamp box.
