Optional LED lighting products of nine things you need to know

　　When consumers buy LED lighting, it is necessary to understand some of the common parameters of LED lighting products, such as: brightness, wavelength, color temperature, etc., identify strengths and weaknesses as a standard. Here to explain the commonly used parameters for the majority of consumers LED lighting products that tell you how to buy LED lighting products.

　　1,brightness

　　Brightness LED lights include:

　　Brightness L: light-emitting body in a specific direction of the luminous flux per unit solid angle per unit area. Unit: Nepal off (cd / m).

　　Flux φ: the sum of the light-emitting amount emitted per second. Unit: Lumen (Lm), said that the number of emitting phosphor, the more lumens luminous greater.

　　Then: the greater the number of lumens, the more luminous flux, the higher the brightness of the lamp.

　　2, the wavelength

　　The same wavelength LED, consistent color. No LED spectral separation device manufacturers is difficult to produce pure colors.

　　3, color temperature

　　Color is the color of the lights identify the units of measurement, expressed as a K value. Yellow is "3300k following" white is "5300k over," there are kinds of intermediate colors "3300k-5300k". Customers can express their personal preferences, application environment and the need to create an atmosphere of lighting effects and pick the right color temperature of the light source.

　　4, the leakage current

　　LED is a one-way conductive light, if there is reverse current is called leakage, leakage current is large LED, short life.

　　5, anti-static capability

　　Antistatic ability of the LED, long life, and therefore higher prices. Usually static than 700V the LED can be used for LED lighting.

　　6, lifespan

　　Quality is the key to a different life, life is determined by the light fades. Light decay, long life.

　　7, design

　　Each product will have a different design, different designs for different purposes, the reliability of the design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, safe use of time and other factors.

　　8, Energy logo

　　Energy labeling is to provide energy consumption and efficiency information to consumers, to facilitate the consumers to buy energy efficient products.

　　9, EU Energy logo

　　EU energy efficiency of products put into seven, won the highest A-class energy efficiency products, G-class is the lowest.
