Smart lighting purchase skills

Smart lighting has many advantages and good performance. It is also widely used in our daily life. Especially in the advertising industry, we will choose cost-effective smart LED lights. There are still some things to pay attention to in the purchase of smart lighting. , Let me introduce you to smart lighting purchasing skills.

Smart Lighting - Beware of the Low Price Trap

The price of LED light source varies greatly, and the price of LEDs with the same color and brightness can be several times different. This gap is mainly reflected in the reliability, light decay, appearance and technology of LEDs. Low-priced LEDs have small chip size, rough electrodes, poor materials (phosphor and glue), poor current resistance, poor temperature and humidity changes, fast light decay, and short lifespan, so blindly pursuing low prices may not be worth the gain.

Smart Lighting - Recognize relevant standards

From a safety point of view, products should comply with relevant national standards. Since LED is a new product, China's national standards are lagging behind, and only product qualification testing is provided. Therefore, safety certification is the standard for measuring the quality of LED lights. There are not many manufacturers with safety certification and national product quality certificate at the same time. It is necessary to carefully identify the authenticity of the certificate when purchasing. Products with national safety certification are generally more expensive.

Smart lamps - LED lamps with constant current power supply

The price of components such as resistors, capacitors, and ICs of LED drive power varies greatly. The solution adopted by the entire power supply and the rationality of the design of the circuit itself will directly affect the quality of the product. Some driving power supply is only constant voltage, and does not achieve constant current, and LED lights must have constant current to better ensure quality and service life. Therefore, this point requires extra attention when purchasing, especially for high-power LED lights.
