With the development of the lamp market, the prices are different according to the materials and technology. How to meet their own budget at the same time, choose a suitable for their own floodlight has become a headache for many friends. In fact, it's not that troublesome. First of all, you should know which parts the LED floodlight mainly consists of.
LED projection lamp mainly consists of two parts, the lamp shell and led integration. Generally, the shell is made of aluminum alloy by one-time die casting. LED is generally used by international brands. The shell is made of aluminum alloy by high-pressure casting, and the surface is shot blasted by high-pressure electrostatic spraying, which effectively improves the heat dissipation performance of the shell.
The high-power floodlight generally adopts high brightness LED light source and high efficiency constant current driving power source, which can save 60% electricity compared with gas discharge lamp; all LED components are sealed, waterproof and dustproof, without internal cleaning and maintenance; the circuit base plate has low thermal resistance, and the specially designed module circuit, each single failure will not affect the normal operation of other components.
The projection lamp is also equipped with a circuit base plate close to the aluminum alloy shell, which can instantly convert the point heat source to the surface heat source, and the heat dissipation area is multiplied, which is conducive to rapid heat dispersion and improve the heat dissipation efficiency; the shell surface has an air flow dispersion groove, which takes away the heat with the help of air flow; the fin density is high, which greatly improves the heat dissipation area, fully guarantees the heat dissipation requirements of the LED, and has a longer service life.
