With the development of the spotlight market, the prices vary depending on the materials used and the manufacturing process. How to choose a suitable spotlight for yourself while meeting your own budget has become a headache for many friends. In fact, it is not so troublesome. First of all, you should understand which parts of the LED floodlights are mainly composed.
LED floodlights are mainly composed of two parts, the lamp housing and LED integration. The outer casing is generally formed by die casting of aluminum alloy. LEDs are generally used in international brands. The outer shell is formed by high-pressure aluminum alloy casting, and the surface is sprayed with high-pressure electrostatic spray to effectively improve the heat dissipation performance of the shell.
High-power floodlights generally use high-brightness LED light source, with high-efficiency constant-current driving power supply, saving 60% than gas discharge lamps; LED components are all sealed, waterproof and dustproof, no internal cleaning and maintenance; low thermal resistance of circuit substrate , specially designed module circuit, each unit failure will not affect the normal operation of the remaining components.
The floodlight is also equipped with a circuit board closely attached to the aluminum alloy casing, which can instantaneously convert the point heat source into a surface heat source, and the heat dissipation area is multiplied, which facilitates rapid heat dispersion and improves heat dissipation efficiency; The air flow takes away heat; the heat sink fin has a high density, which greatly increases the heat dissipation area, fully guarantees the heat dissipation requirement of the LED, and has a longer service life.
