LED lighting market, there is such a lamp, called LED explosion-proof lamp. From the name point of view, we probably know what the function and advantages of LED explosion-proof lamp are. LED explosion-proof lamp source selection is LED light source, LED light source has what basic performance, lead to LED explosion-proof lamp selection? Today, Xiao Bian and we talk about the basic properties of LED light source, and only fully understand the basic performance of LED officials, in order to better protect lamps and lanterns, increase the service life of lamps.


1, brightness. LED's brightness is different, the price is different. Therefore, when choosing the LED light source, we need to pay attention to the brightness of the light source.


2, antistatic ability. Antistatic LED light source, longer life, and therefore higher prices.


3 and wavelength. Wavelength consistent LED, color consistent, such as the same color requirements, the price is high.


4, leakage current LED is a one-way conductive light, and if there is reverse current, it is called leakage, leakage current of large LED, short life, low price.


5, light angle. Different uses of LED, the light angle is not the same. Special light angle, higher price. Such as full diffusion angle, higher prices.


6, life. Different quality is the key of life, life is decided by the light fades. A small decline, long service life, long service life, high price.


7, wafer. LED's light source is wafer, and the price varies greatly with different chips. The wafers in Japan and the United States are more expensive. In general, the prices of wafers made in Taiwan and China are lower than those in Japan and america.


8, chip size. The size of the wafer is indicated by the length of the side, and the quality of the large wafer LED is better than that of the smaller one. The price is proportional to the size of isomorphous.


9, colloid. Ordinary LED colloid is usually epoxy resin, plus anti UV and fire retardant LED more expensive, high-quality outdoor LED lighting should be anti ultraviolet and fire. Each product has a different design, and different designs are suitable for different uses.
