Characteristics of low frequency led high bay lamps
Now a lot of people on the understanding of led high bay lamps just stay in the concept of books, especially for high frequency led high bay lamps, low frequency led high bay lamp awareness there are many errors. Electronic lighting professionals analysis of high frequency led high bay lamps and low frequency led high bay lamp between the main differences are the following:1, EMC electromagnetic interference test. High-frequency led high bay lamps have radiation, the national grid, the electrical equipment interference, it is difficult to pass EMC testing, so in Europe and the United States has banned GM. The low-frequency electrodeless lamp can be detected by EMC, electromagnetic radiation problem is basically solved in Europe and the United States is very popular.2, electronic ballasts. High frequency led high bay lamp is self-excited shock, by external electrical interference serious, high temperature, can not dim. Low-frequency led high bay lamp using IC chip and wide voltage design, high power factor, low current harmonics, intelligent dimming.3, the price. Low-frequency led high bay lamp prices will be higher than the high frequency Mainly because the low-frequency led high bay lamp lamp structure is special, generally ring, rectangular, its production technology and high technological content, the need for complex and expensive equipment to achieve mass production. The high-frequency led high bay lamp structure is relatively simple, mainly bubble-shaped, olive-shaped, you can use simple equipment production, production technology and technical content is low, so the price is relatively low.
4, heat problems. High frequency industrial lamp built-in coupler, the core temperature of 350OC, so the heat problem is difficult to solve, the ballast in the electronic components is difficult to work in high temperature environment, so the high frequency to do the small wattage The frequency power is 10 watts to 165 watts. The low-frequency led high bay lamp is an external coupler, the magnetic ring temperature in the 160OC, low-frequency power can be done 10 watts -400 watts.5, light effect. High-frequency led high bay lamp light efficiency is generally only 50-60lm / w, while the low frequency can reach 80-90lm / w. Equal power of low-frequency industrial and led high bay lights than high-frequency high-frequency 25%, brightness will naturally be high 25%. The main reason is that high frequency led high bay lamp ballast conversion efficiency is low, the coupling high frequency loss is large, and high frequency led high bay lamp too high temperature will cause the damage to the phosphor, the light effect in 1000 hours decay 30%. While the low-frequency led high bay lamps due to lower operating temperature, 1000 hours of light failure only 7%, low-frequency led high bay lamp ballasts and couplers are working at about 1/10 high frequency led high bay lamp frequency, high frequency loss greatly reduced , So that the light effect has been further improved. Technology patents, low-frequency led high bay lamps in foreign countries have patent barriers, and high-frequency led high bay lamps are not. shape. High frequency led high bay lamps are generally bubble-shaped, low-frequency led high bay lamps are generally round and rectangular. So high-frequency led high bay lamps easily equipped with lamps, and low-frequency more difficult to match lamps. Warranty. Low-frequency led high bay lamp warranty period is generally 5 years, while the high-frequency led high bay lamp only 3 years.frequency. High frequency led high bay lamp operating frequency of 2.65 MHz, the equivalent of short-wave radio operating frequency. Low frequency of 200-250 kilohertz, equivalent to the working frequency of the wave radio.
