Tell you how to choose LED light beads

The main outstanding advantages of LED lamps are energy conservation, long lifespan, environmental protection, and arbitrary control of light and color. Led, as a new high-tech lighting product in the 21st century, its production technology is constantly improving and improving. At present, there is no complete product standard in China, and the quality of LED lamps varies. At present, there are many manufacturers of LED lighting, and the market price war is becoming increasingly fierce. Choosing different quality LED lighting quality is an important reason for each manufacturer. The appearance, structure, and function of LED products are almost the same, with a price difference of 2-3 times. Users and buyers lack knowledge of LED products and lack product testing methods. I don't know how to understand the price differences, how to choose LED lamps or identify the quality of LED lamps.

1、 Lamp bead quality:

1. Led chip; The commonly used brands are divided into three main camps: American chips, Japanese chips, and Chinese chips. LED chips of different qualities are the key to life, and life is determined by light decay. Low light attenuation, long lifespan, long lifespan, and high price. The quality of the chip determines the brightness and light decay of the lamp beads. A good lamp bead not only has high brightness but also low attenuation.

2. Light effect: A lamp bead with the same power, the higher the light effect, the higher the brightness. The same lighting control brightness, the lower the power consumption, the more energy-saving. The better the color temperature of the same batch of lamps remains consistent and develops, the higher the price level.

2、 Drive power supply;

LED lighting fixtures must be equipped with high-quality and efficient driving system power supplies. Students are required to achieve a power factor of 0.9 or higher for the driver. If the power control factor level is lower than 0.6, it is considered an unqualified product or a waste product. Not only does it have a short lifespan, but China's actual electricity consumption is about twice that of the nominal, without any energy-saving effect. At the same time, the current harmonics are also large, and the current is unstable, which affects the lifespan and integrity of the lamp beads

The lifespan of body lamps is unfavorable. The lifespan of the power supply directly affects the overall lifespan of the lamp. The theoretical lifespan of LED beads is greater than 50000 hours, while the lifespan of the power supply is between 5000 and 30000 hours. Without a good driving power supply, LED lamps cannot guarantee product quality and lifespan.

3、 Heat dissipation conditions;

Radiator material; Nowadays, radiator materials are generally made of aluminum alloy, with the better option being to insert aluminum alloy, followed by aluminum cars (aluminum profiles, aluminum extrusion), and the worse option being cast aluminum.

2. The structure of the heat sink: The contact area and assembly tightness between LED beads, aluminum substrate, and aluminum shell can directly affect the conduction and heat dissipation effect of the core operating temperature of the LED chip.

3. Radiator area; The size of the heat sink area of LED lamps determines the heat dissipation effect of LED lamps. If the heat dissipation conditions are not good, the lamp beads will work at high temperatures, resulting in significant light attenuation and shortened lamp life.

4、 Safety standards;

Some enterprises in China have already introduced safety management standards for LED lighting fixtures. Please choose LED lighting fixtures according to the safety education standards stipulated by our national laws. A LED lamp with good learning quality also needs to fully consider the different network environments and technological development requirements of students, such as moisture and dust prevention. In short, a high-quality LED light fixture requires a perfect combination of high-quality (chip) beads, high-quality (chip) beads, drive system power supply, good heat dissipation conditions, and compliance with social safety production standards! Emphasizing only one party cannot be considered a qualified product. Therefore, when choosing LED lighting fixtures, consumers should comprehensively analyze and consider the above important aspects to avoid causing losses to rural economic benefits.
