CHUN WAH INTERNATIONAL TRADING LIMITED

We produc and sell electrodless discharge lamp. The electrodeless discharge lamp is composed of radio-frequency alternator, coupler and bulb. The coil twisted on the magnetic core is called coupler, when the coupler obtains high-voltage inceptive pulse provided by the power source, can the mercury steam in the bulb be stimulated to plasma. And the following 2.65 megahertz of high frequency pulse, approximately 300-500 volts continues stimulating the plasma drive, causing the outer-shell electron to become excited, and unceasingly carrying jumps and shines. The power supply of electrodeless discharge Lamp may be regarded as a combination of frequency charger and transformer; it may connect to electrical network directly with input voltage of 110 volts to 240 volts, or input of Direct Current in any voltage, the electrodeless discharge Lamp is then served as an emergency light.Technical characteristic:Ultra long life, termination of traditional filament and electrode, started up by electromagnetic induction and high frequency triggers, work stably. The usage life is up to 60,000 hours, t0 times as an Incandescent Lamp and 4 times as a High-pressured Sodium Lamp.Redundant reliability, maintenance is unnecessary; disburden concern of repairing and cost of replacement, no need of human guarding and avoiding of maintenance cost.
