With the increasing development of light sources, LEDs have become the most promising emerging products. Compared with incandescent lamps and fluorescent lamps, LEDs are small in size, can be combined in multiple combinations, have low calorific value, basically have no heat radiation, and consume electricity. Small quantity, can be started with low voltage and low current, long service life, working time can reach more than 10,000 hours, fast response, can operate at high frequency, and is environmentally friendly, shock-resistant, impact-resistant and not easy to break, and can be recycled as waste. There is no pollution, and it can be flat-packaged and easily developed into thin, light and short products.

However, when LED is used as the light source of lamps and lanterns, it is necessary to install an additional power drive module to drive the LED to work. The power drive module will emit more heat when it is working. High-end tri-proof lights rarely use LEDs as light sources.

As a further improvement, the LED tri-proof lamp provided by the present invention also includes a power drive module for driving the LED module. The back connection of the middle connecting piece. This method of placing the power drive module outside the lamp body can avoid the interference of the heat dissipation of the LED work and the work heat dissipation of the power drive module, and is beneficial to the overall heat dissipation of the lamp body.

As a further improvement, an L-shaped installation strip is arranged outside the drive housing, and the L-shaped installation strip is slidably arranged in the slideway.

As a further improvement, waterproof joints are sealingly connected to the cover plates at both ends of the drive housing, and holes for passing power lines are provided in the waterproof joints, and through holes for passing power lines are also provided on the end covers.

As a further improvement, the lamp base is also connected with a lamp body installation bracket and a hook arranged on the bracket.

Compared with the prior art, the present invention has the advantages that: since the base of the lamp is set as an integrally formed aluminum profile structure, and the front of the intermediate connecting sheet is set as a plane, the intermediate connecting sheet can just be used as a reflector without the need for Additional reflectors are provided, and multiple cooling fins are provided on the back of the middle connecting piece. The bottom plate can be used not only as the bottom plate of the lamp body, but also as a radiator, which can achieve a better heat dissipation effect.
