Among various commercial lighting projects, the high-power LED light is a kind of LED lighting lamps. For example, compared to low-power LED downlights, high-power LED downlights have higher power, brighter and higher price. Of course, because there are many parameters of high-power LED downlights, there will be different classification standards according to different parameters.
The following are the purchasing tips for high-power LED lights.
First,see the light quality and anti-glare effect. Whether the light spot is beautiful or not affects the effect directly. The anti-glare performance is critical.
Second, the same lamp bead power, the higher the luminous efficiency, the higher the brightness, the same lighting brightness, the lower the power consumption, the more energy-saving.
Third,see the color temperature. Whether the color temperature distribution is uniform or not will affect the lighting effect directly.The higher the efficiency of the power supply, the better. The higher the power consumption, the lower the power consumption and the greater the output power..
Fourth,The low power factor of LED lamps indicates that the driving power and circuit design used are not good, which will reduce the service life of the lamps.
Fifth,the thermal resistance of LED lamps is low and the heat dissipation is better. If the thermal resistance is high, the heat dissipation will be poor.Excessive temperature rise also directly affects the service life of high-power LED downlights.
At last,the material and structure of the heat dissipation conditions of the lamps and the heat dissipation of high-power lamps are also very important. For lamps with the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads will work under high temperature, the light decay will be large, and the lamp life will be cut back.The quality of LED lamp beads is determined by the chip quality and packaging technology.
