高频无极灯介绍
COMPANY Profile
高频无极灯由高频发生器、耦合器和灯泡三部分组成,
●高频发生器
高频发生器主要包括振荡器、滤波器、整流器、开关器件、匹配网络、驱动线圈和电弧的等效电路。它为耦合器提供一个高频能量来激发和维持灯泡内的气体放电。高频发生器必须有一个很稳定的振荡源和过滤电路,同时,它还有一个高的功率因数和一个低的谐波含量。高频发生器的输出频率是2.65MHz。
●耦合器
耦合器是把能量从高频发生器经线圈耦合到灯泡内的器件。它由磁芯、高温线、导热棒、绕线架、底座、过渡件和同轴电缆组成。
磁芯和高温线的作用是产生高频磁场。通过中间的导热棒,线圈产生的多余的热能和放电通过铝制底座传导到外面。底座有两种功能:一是保证灯泡和耦合器的连接;二是把多余的热传给散热片,这个散热片必须是灯具的一部分。通过螺丝与灯具散热片连接。
●灯泡
灯泡主要是一玻璃灯泡,主要由涂有保护膜和三基色荧光粉的泡壳、内管、汞齐、辅助汞齐等以及灯头组成,内部充有低气压汞和惰性缓冲气体。
其工作原理是:将高频电磁场能量以感应方式耦合到灯泡内,使灯泡内的气体被击穿形成等离子体,等离子体受激原子返回基态时,辐射出254nm的紫外线,灯泡内荧光粉受到紫外线激发而发出可见光。
无极灯特性
Lvd lamp working principle
长寿命:平均寿命10万小时,常年使用免维护
高光效:65-90Lm/w
高显色:》80,色彩分辨更逼真
无频闪:光线柔和,保护视力
低光衰:6万小时光通量维持率不低于70%
恒功率:电源电源波动+-10%输出灯功率变化小于+-3%,保证光输出恒定
快速启动:即开即亮(具有热灯瞬时启动能力,与HID灯比,具有明显优势)
环境适应性强,在-20~+50的环境下正常工作,可以设计在-40工作的灯泡
可选色温范围广:2700-6500K,可以满足各种场合需求
绿色用电,专利设计,电磁兼容(EMI)符合标准要求,消除了对环境及电网的污染
Long life: Average life of 100,000 hours, year-round use of maintenance-free
High efficiency :65-90Lm / w
High-color: "80, more realistic color resolution
No flash: light, soft, protect eyesight
Low-light failure: 60,000 hours Luminous flux maintenance rate of not less than 70%
Constant Power: Power supply fluctuations + -10% change in the output light power of less than + -3%, to ensure constant light output
Quick Start: which means that the light (with a heat lamp instant start capability, compared with HID lamps, has a clear advantage)
Environmental adaptability, -20 ~ +50 working environment can be designed to work in a light bulb -40
Wide range of selectable color temperature :2700-6500K, to meet the needs of a variety of asions
Green electricity, patented design, ic compatibility (EMI) compliance requirements, eliminating the pollution of the environment and the grid
