Microwave metallic halogen lamp

Abstract

The invention discloses a microwave gold halogen lamp including a magnetron which is arranged in casing and can generate microwave energy under electric power; a wave guide cavity which is communicated to the magnetron and transmits microwave to a resonant cavity capable of making microwave energy resonance; a bulb which is arranged in the resonant cavity and can emit light by microwave energy excitation; and a bulb motor for driving the bulb rotate. The bulb is filled with luminescent working material and inert gas, wherein the luminescent working material is metal halides or metal halides and a small quantity of additive. By adjusting proportion of the metal halides, components and pressure of the inert gas, the microwave gold halogen lamp has excellent color parameter and power range, is substitute of microwave sulfur lamp, gold halogen lamp and high voltage sodium lamp, has wide application range, increases lighting effects and is more energy-saving. A prepared 3500K low color temperature lamp with golden light and strong fog penetrability is specially adapted for situation of port, dock and road illumination.

Description

Technical field: [0001] The invention relates to a light source, in particular to a microwave metal halide lamp. Background technique [0002] The current microwave sulfur lamp, whose luminescent working substance is mainly sulfur element, can only emit white light, the color temperature is generally above 7000K, and the power is also above 1000W, which greatly limits its application occasions and is not conducive to the promotion of energy-saving lighting; the above-mentioned existing microwave The disadvantages of sulfur lamps are: they can only be made into high color temperature lamps but not low color temperature lamps, resulting in poor fog penetration ability; they can only be made into high power lamps but not medium and low power lamps, low luminous efficiency and color rendering The index is low and the scope of application is narrow. [0003] However, the metal halide lamps in the prior art all need electrodes. Due to the loss of the electrodes, the lamp life is ...

[0002] The current microwave sulfur lamp, whose luminescent working substance is mainly sulfur element, can only emit white light, the color temperature is generally above 7000K, and the power is also above 1000W, which greatly limits its application occasions and is not conducive to the promotion of energy-saving lighting; the above-mentioned existing microwave The disadvantages of sulfur lamps are: they can only be made into high color temperature lamps but not low color temperature lamps, resulting in poor fog penetration ability; they can only be made into high power lamps but not medium and low power lamps, low luminous efficiency and color rendering Low index, narrow application range

[0003] However, the metal halide lamps in the prior art all need electrodes. Due to the loss of the electrodes, the lamp life is generally 8000-12000h, and the best is no more than 15000h. The disadvantages of the above-mentioned existing metal halide lamps are: large light decay, low life span, Large color drift, poor stability of optical and electrical parameters
