High-power LEDs will generate a lot of heat when working, causing the light source temperature to be too high. If the heat is not dissipated in time, it will affect the light efficiency of the light source or even burn it out. Utility Model Content

[0028] In the above embodiment, the front gland 1, the lamp body 2 and the rear end cover 3 are all made of aluminum alloy material through a surface anti-corrosion process. The upper end of the front gland 1 is connected with a light-transmitting mirror 11, which is made of acrylic or sapphire glass to ensure that it will not bend or break when squeezed by the operating water depth pressure.
