With the development of technology, LED outdoor lamps are becoming more and more popular. After the development of LED technology, lamps have become a factor in market competition.
The first is the price factor of led outdoor street lights. Modular LED street lights are made of aluminum profiles, so the cost is very low; the upper and lower transparent heat dissipation lamps reduce the weight of the lamps and reduce the cost of the lamps by changing the heat dissipation structure.
It can be made close to the price of LED street lamps with modular street lamps.
The second reason is that the types of light sources are different. Although customers are slowly accepting integrated light sources, there is still a distinction between integration and single light sources.
For these two kinds of light sources, neither of them will be completely abandoned in the next 1-2 years. Therefore, the choice for LED street lamps is modular street lamps and integrated street lamps with upper and lower transparent heat dissipation.
How to distinguish good quality floodlights is a very important issue
Most of the LED floodlights are used inside, and some may like to be used outdoors, but the principle is similar. How do we buy high-quality floodlights, we must have basic knowledge when buying things, so as to avoid some bad manufacturers. Deceived.
1. Look at the material:
Heat dissipation depends on the material. Choose aerospace polymer materials, which have excellent heat dissipation performance, high temperature resistance and electric shock resistance, and are more portable. At present, the light efficiency utilization rate of high-power LEDs is limited, and most of the remaining energy is converted into heat energy. If the heat energy cannot be effectively discharged, it will directly affect the service life of the lamp, so heat dissipation is very important. Be sure to choose lamps with good heat dissipation when purchasing!
2. Look at the wattage:
Some manufacturers of 100w can't make it so high, it may only look like 50w or 75w, commonly known as 0.5w and 0.75w. To test the power, just buy a multimeter and actually measure it. For the quality and size of the light source chip, in order to reduce costs and improve competitiveness, manufacturers use low-quality lamp beads with less than W.
3. Look at the power supply:
Take a look at the power supply. In order to save costs, some manufacturers have not added a waterproof epoxy resin in the power supply, and the power supply is waterproof.
The power supply is assembled from a lot of electronic parts. After assembly, it needs to be aged and tested before being assembled into a floodlight.
The life of the power supply directly affects the overall life of the lamp. Please consult the merchant about the various parameters of the drive, such as output voltage and current, working temperature, protection level and so on. The power supply of the flood light is to be glued and waterproof.
4. Look at the seal:
If the waterproofing is done well, it is not easy to enter water if the sealing is done well, that is to say, the waterproof performance is good, as long as the lamp housing is good, plus a good sealing strip, it must be above IP65.
Floodlights are rain-proof and moisture-proof for outdoor use. If they are soaked in water for a long time, there are potential safety hazards. It is recommended to use professional lamps in the water, such as underwater lights, buried lights, etc., which are tightly packaged.
5. Look at the craft:
The quality of the whole lamp is related to the power supply, light source and sealing strip, the thickness of the cable, the use of thermal grease, and the level of workmanship (attentiveness, welding process) of the workers. Workers in small workshops do not wash their hands, let alone those anti-static clothing.
