Comparison of lighting and LED

Lighting and LED are compared from the following four aspects: 　　 1. Light efficiency: High-frequency lighting luminous efficiency is greater than 60-80Lm/w, while LED lighting efficiency is about 100Lm/w. Since LED lights cannot be directly illuminated, they need to be equipped with anti-glare glass, which blocks part of the light. In addition, LED lights are integrated and increase luminous points per unit area. Therefore, if a single lamp is compared, the lighting efficiency of the lighting is high, but the LED lamp The integrated luminous efficiency is slightly higher than the lighting. 2. Luminous decay: When the high-frequency lighting is used for 60,000 hours, its lumen maintenance rate can maintain more than 70%, but because the light decay is difficult to control, some of the lumen has dropped by 50% when it is only used for less than 1,000 hours. the above. 3. Visual effect: the color temperature of high-frequency lighting is 2700k-6500k, various colors can be customized, the color rendering index can reach 80, high frequency without flicker, looks more realistic than other light sources, and the 120w LED is made of many small watts It is packaged with several LEDs and is a multi-point light source. Therefore, under the LED light, the picture is dim, the color is deviated, the overlap is heavy, and the light pollution is prominent, which can easily cause visual fatigue and even cause traffic safety problems. 4. Life: High-frequency lighting has no filament and electrode, long life, ≥60,000 hours, strong environmental adaptability, temperature between -25℃-50℃, power supply between 100V-265V, and strong shock resistance, general The life span can reach more than 100,000 hours; the life expectancy of LED lights is also 100,000 hours, but due to packaging, design, assembly and other issues, especially heat dissipation issues cannot be effectively resolved, the actual life span is greatly shortened, and many malfunctions occur after less than 1,000 hours of use. Especially when combined into a high-power lamp, the performance of the LED lamp deteriorates severely as the use time increases, and the degree of deterioration is affected by environmental temperature, operating current, and voltage drop. In order to make the LED light brighter, the driving current can only be increased, which leads to excessive heat generation, which reduces the brightness of the lighting or even burns
