Detailed Implementation Methods

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0017] It should be noted that in this embodiment of the invention, all directional indications (such as up, down, left, right, front, back, etc.) are limited to relative positions on the specified view, rather than absolute positions.

[0018] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] Please see Figures 1 to 3 The explosion-proof LED bracket light for mining is suitable for use in underground coal mines with explosive mixtures of gases such as methane and coal dust. It can be used for lighting in the working face, as well as for lighting in roadways and tunnels, or for lighting in mining hydraulic supports. It includes a bottom shell 10 and a top shell 20, which are fixedly connected by screws.

[0020] The bottom shell 10 includes a front cavity 11 and a rear cavity 12. A partition 16 is provided between the front cavity 11 and the rear cavity 12, which divides the front cavity 11 and the rear cavity 12 into two independent cavities.

[0021] The front cavity 11 is equipped with a lamp board, which is a light source cavity. The rear cavity 12 is equipped with a circuit board and a power supply, which is a power supply cavity. The partition 16 is provided with a plurality of wire holes 13, which are used to pass wires to connect the lamp board and the circuit board.

[0022] This utility model of an explosion-proof LED bracket light for mining adopts an independent structure design for the light source cavity and the power supply cavity, which reduces heat conduction to the constant current source, ensures normal operation of the product for a long time, and helps to extend the service life of the lamp.
