Purchasing skills of intelligent lamps

Intelligent lamps have many advantages and good performance. They are also widely used in our daily life. Especially in the advertising industry, we will choose intelligent LED lamps with high cost performance. We still need to pay attention to some matters in the purchase of intelligent lamps. Let's introduce the purchase skills of intelligent lamps.

Smart lighting - beware of low price trap

The price of LED light source is very different. The price of LED with the same color and brightness can vary several times. This gap is mainly reflected in the reliability and light decay of LED, appearance technology and other performance. LED chips with low price have small chip size, rough electrodes, poor materials (fluorescent powder and glue), poor current resistance, poor temperature and humidity change, fast light decay and short life, so it may not be worth pursuing low price.

Intelligent lamps - recognize relevant standards

From the point of view of safety, the product should meet the relevant national standards. As LED is a new product, China's national standard lags behind and only provides product qualification test. Therefore, safety certification is the standard to measure the quality of LED lights. At the same time, there are not many manufacturers with safety certification and national product quality certificate, so it is necessary to carefully identify the authenticity of the certificate when purchasing. The price of products with national security certification is generally high.

Intelligent lamps - LED lamps with constant current power supply

The price of resistance, capacitance, IC and other components of LED driving power supply varies greatly. The rationality of the whole power supply scheme and circuit design will directly affect the product quality. Some driving power supply is only constant voltage, not constant current, and LED lights must be constant current to better ensure the quality and service life. Therefore, this point needs extra attention when purchasing, especially for high-power LED lights.
