Introductions about Electrodeless Lamps

Electrodeless lamp is an abbreviation of the Promise Light high frequency plasma discharge lamp. It is the high-tech product integrated the latest scientific and technological achievements in the field of application optical, power electronics, plasma, magnetic materials and other research and development, which is the new light source representing lighting technology high light efficiency, long-life, high color rendering future direction.

The electrodeless lamp belongs to the fourth generation lighting products, no filament, no electrode, which is the abbreviation of no electrode gas discharge fluorescent. Compared with the traditional energy-saving lamps, metal halide, high pressure sodium light sources, it has significant advantages.

Principle

The electrodeless lamp is composed by three parts of the high-frequency generator, couplers and bulb. It is coupled to the lamp by the electromagnetic wave of high-frequency generator through induction, so that the gas inside the bulb avalanche ionization to form plasma. Plasma is excited and atoms return to the ground state, the ultraviolet is radiated. The phosphor excited by ultraviolet lamp lining to produce visible light.

Advantages and disadvantages:

1. High frequency induction lamp has small size, bulb shape changes more, which can be equipped with many lamps. The old induction bulbs can also be used after making a little modification. Higher light efficiency under the same power. The light bulb use nano-level the alumina coating to eliminate electromagnetic radiation. But the disadvantage of high-frequency induction lamp is obvious. Poor heat dissipation, resulting in low power, most manufacturers only do 200W for the sake of stable quality.

2. Low-frequency induction lamp power can be bigger, high-power electrodeless lamp is the existence that other commonly used conventional lighting cannot match, external coupler, bulky lamp, the cooling effect is also very good. But the fittings can be equipped with lamps is very small because of the large volume, resulting in a loss of some lumens. Further, the external coupler causes the leakage of a small amount of the electromagnetic.

Electrodeless lamp light efficiency deficiencies:

The electrodeless lamp theoretical light efficiency is only 80Lm / W, but the luminous efficiency of the actual product is only 65Lm / W, compared to energy-saving lamps, it is quite impossible to compete with sodium lamp / metal halide currently used in street lights (sodium / metal halide light efficiency is 110Lm/W--120Lm/W). Because the lighting efficiency of electrodeless lamp is low, compared with sodium lights, sending out the same light means more power consumption and more heat dissipation. It will be darker if you replace 250W sodium lamp with 185W electrodeless lamp, do not argue the fact.
