The structure of the LED lamp is mainly divided into four parts: the structure of the light distribution system, the structure of the heat dissipation system, the drive circuit and the mechanical/protective mechanism. The light distribution system is composed of LED light plate (light source)/heat conduction plate, light equalizing cover/lamp shell and other structures. The heat dissipation system is composed of heat conducting plates (columns), internal and external radiators, etc; The driving power supply is composed of high-frequency constant current source and linear constant current source, and the input is alternating current. The mechanical/protective structure consists of radiator/shell, lamp cap/insulating sleeve, light equalizing cover/lamp shell, etc.

Compared with the electric light source, LED lamps are quite different in terms of luminous characteristics and structure. LED mainly has the following structural features:

1. Innovative light distribution design. The light spot is rectangular by reasonably controlling the light distribution. According to different light distribution designs, its effective luminous angles are roughly divided into less than 180 degrees, between 180 degrees and 300 degrees, and more than 300 degrees, to ensure the ideal road brightness and uniform brightness, while eliminating the glare of LED and maximizing the light energy utilization without light pollution.

2. Integrated design of lens and lampshade. The lens array has the functions of light gathering and protection at the same time, avoiding the repeated waste of light, reducing the light loss, and simplifying the structure.

3. Integrated design of radiator and lamp housing. It fully guarantees the heat dissipation effect and service life of LED, and fundamentally meets the requirements of LED lamp structure and arbitrary design.

4. Modular integrated design. It can be arbitrarily combined into products with different power and brightness. Each module is an independent light source and can be switched. Local failure will not affect the whole, making maintenance simple.

5. Compact appearance. It effectively reduces the weight and increases the safety.

In addition to the above structural features, Industrial LED flood lamps also have the following functional advantages: intelligent control of current detection, no bad glare, no light pollution, no high voltage, no dust adsorption, no delay, no stroboscopic, withstand voltage, strong seismic resistance, no infrared and ultraviolet radiation, high color rendering index, adjustable color temperatures, energy conservation and environmental protection, an average life of more than 50000 hours, and universal input voltage worldwide It has no pollution to the power grid, can be used in combination with solar cells, and has high luminous efficiency.
