At present, many exhibition halls, offices and other places use LED panel lights, and panel light manufacturers specialize in panel lights, including: ultra-thin panel lights, square panel lights, rgb panel lights, then when selecting the point light source of led panel lights, And pay attention to what problems, Jiuzheng Building Materials Network will introduce you from the following aspects. 1, brightness: LED brightness is different, the price is different. LEDs for LED luminaires shall comply with the laser class I standard. 2, anti-static ability: LED anti-static ability has a long life, but the price of LED lights is also high. LEDs with an antistatic greater than 700V are usually used for LED lighting. 3. Leakage current: The LED is a unidirectional conductive illuminator. If there is a reverse current, it is called leakage. The LED with large leakage current has a short life and the price is relatively low. 4, the angle of illumination: LEDs with different uses have different illumination angles. For example, the illumination angle of the led panel lamp has 30 degrees or 160 degrees, etc. Generally, there is a special illumination angle, and the price is high. If the full diffusing angle, the price will be higher. 5, wafer: LED illuminator is a wafer, different wafers, the price difference is very large. The chips in Japan and the United States are relatively expensive. Generally, the prices of Taiwanese and domestic wafers are lower than those of Japan and the United States. However, in terms of quality, the quality of imports is better than that of domestic ones. 8. Wafer size: The size of the wafer is expressed by the side length. The quality of the large wafer LED is better than that of the small wafer. The price of LED lamps is proportional to the size of the wafer. Generally, the commonly used wafers are 3528 and 5050. 9. Colloid: The colloid of ordinary LED is generally epoxy resin. LEDs with anti-ultraviolet and fire retardant are more expensive. High-quality outdoor LED lighting should be resistant to ultraviolet rays and fire. China Searun Solar Solution Co., Ltd. , https://www.searunsolar.com
