低频无极灯介绍
Lvd lamp working principle
●低频无极灯概念：
低频无极灯是为了和高频无极灯区分而取的名字。
高频无极灯的频率一般在2.50MHz~2.65MHz范围，而低频无极灯的频率一般在230~250KHz范围，目前世界上有的国家低频无极灯的频率是采用140KHz。常用电压有：交流220V，直流12V、24V、36V，定制电压有：交流110V、直流48V。
●低频无极灯的灯管（形状）：
低频无极灯的灯管形状有“矩形”、“环形”、和小功率“U型螺口一体化”、“圆泡形”。同高频无极灯相比，低频无极灯的发生器发热量小，可制作大功率无极灯。
●低频无极灯工作原理：
低频无极灯和高频无极灯原理一样，没有传统光源的灯丝和电极，主要由高频发生器、环形功率耦合器和玻璃泡壳三部分组成，通过电磁感应方式将能量耦合到灯泡内，是综合功率电子学、等离子体学、磁性材料学等理论开发出来的高新技术照明产品。灯泡内充有适量的特种气体，高频能量使之电离或激发，激发后的原子从较高能级返回基态时，发出紫外光子，紫外光子激发泡壳内壁的三基色荧光粉产生可见光。
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 occasions
Green electricity, patented design, electromagnetic compatibility (EMI) compliance requirements, eliminating the pollution of the environment and the grid
无极灯可广泛用于：
城市亮化照明、景观绿化照明、工厂车间、学校教室、图书馆、问世蔬菜植物棚、礼堂大厅、会议室、大型商场天花板。高顶高危厂房、运动场、隧道、交通复杂地带（路灯、标志灯、桥梁灯）、地铁站、火车站危险地域照明、水下灯等特别适用于高危和换灯困难且维护费用昂贵的重要场所如：矿山、矿井照明等。
Lamp can be used:
City lighting lighting, landscaping lighting, factory floor, classrooms, libraries, the advent of plant vegetable shed, auditorium halls, conference rooms, shopping malls ceiling. High-top high-risk plants, stadiums, tunnels, transportation complex area (lamps, marker lamps, bridge lamps), subway stations, train stations hazardous area lighting, underwater lights, especially for high-risk and change difficult and expensive to maintain light an important place such as: mining, mine lighting.
