Nowadays, all aspects of society have involved the application of LED lamps, ranging from shopping malls to office, to audio-visual entertainment. Whether it is from the brand concept to the product itself, it has attracted the pursuit of all walks of life, but due to the type of lamp group There are many items, and the quality is relatively uneven. In this way, choosing a model suitable for your own use according to the different parameters of the lamps has also become a topic that buyers are very concerned about. Common parameters of LED lighting products, such as: brightness, wavelength, color temperature, etc., are used as the standard to distinguish good and bad uses. The following will explain the common parameters of LED lighting products for the majority of buyers, and tell you how to buy LED lighting products. 1. Brightness The brightness of the LED lamp includes: Brightness L: the luminous flux of the luminous body per unit solid angle and unit area in a specific direction. Unit: Nitre (cd/㎡). Luminous flux φ: the sum of the amount of light emitted by the luminous body per second. Unit: Lumen (Lm), which indicates how much the luminous body emits, the more luminous, the greater the number of lumens. Then: the larger the number of lumens, the more luminous flux, and the higher the brightness of the lamp. 2. Wavelength LEDs with the same wavelength have the same color. It is difficult for manufacturers without LED spectrophotometers to produce products with pure color. 3. Color temperature Color temperature is a unit of measurement that identifies the color of light, expressed in K value. Yellow light is 'below 3300kCustomers can choose a light source with a suitable color temperature according to their personal preferences, application environment, and lighting effects and atmosphere to be created. 4. Leakage current LED is a one-way conductive luminous body. If there is a reverse current, it is called leakage current. LEDs with large leakage current have a short lifespan. 5. Antistatic ability LEDs with strong antistatic ability have long life and high price. Usually LEDs with anti-static greater than 700V can be used for LED lighting (lighting decoration renderings). 6. Lifespan The key to different quality is lifespan, which is determined by light decay. Low light decay and long life. 7. Design Each product will have a different design, and different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, and safe use time. And other factors. 8. Energy labeling Energy labeling is to provide consumers with information such as energy consumption and benefits to facilitate consumers to purchase high-efficiency products. EU energy label The EU divides the energy efficiency of products into 7 grades, with A-grade products having the highest energy efficiency and G-grade being the lowest. China Energy Efficiency Label China Energy Efficiency Label is a color label with a blue and white background. It is divided into 5 levels. The meaning of each level is as follows: Level 1: The product has reached the international advanced level, the most energy-saving, that is, the lowest energy consumption; Level 2: Comparatively energy-saving; Level 3: The energy efficiency of the product is the average level of the Chinese market; Level 4: The energy efficiency of the product is lower than the market average level; Level 5: The market access standard (products below this level are not allowed to be produced and sold).
