Problems solved by technology

For example: incandescent lamps have the advantages of high dominance, high power factor, and immediate start, but low luminous efficiency and short life
The life of compact energy-saving lamps is relatively extended, but non-recyclable liquid mercury is used, causing environmental pollution
Halogen tungsten lamps, high-pressure sodium lamps, high-pressure mercury lamps, and metal halide lamps all have defects such as high ultraviolet content, slow startup, cumbersome maintenance, low color rendering, short service life, and low power factor.
Moreover, these lighting sources all use filaments or electrodes, and the sputtering effect of filaments or electrodes is the key factor that limits the life of the light source

Embodiment Construction

[0018] As shown in the figure: a high-power high-frequency electrodeless fluorescent lamp, a power coupler 3 is installed in the center cavity 2 of the bulb shell 1, and the power coupler is connected with the high-frequency generator; the inner surface of the bulb shell is coated with a luminous coating Layer 4; the main amalgam 5 is installed at the bottom of the bulb body, and the auxiliary amalgam 6 is installed outside the central cavity. The above-mentioned luminescent coating is a three-color phosphor layer.

[0019] The working principle of the present invention is: the high-frequency electromagnetic field energy is coupled into the bulb in an inductive manner, so that the gas in the bulb is broken down to form plasma, and when the plasma excited atoms return to the ground state, 254nm ultraviolet rays are radiated, and the bulb fluoresces The powder is excited by ultraviolet light to emit visible light.

Abstract

The invention relates to a high-power high-frequency electrodeless fluorescent lamp. A power coupler is arranged in a central cavity in a shell; the power coupler is connected with a high-frequency generator; the inner surface of the shell is coated with a luminous coating; the bottom of the shell is provided with primary amalgam; and the outer side of the central cavity is provided with secondary amalgam. The fluorescent lamp has the advantages of: 1. ultralong service life which reaches as long as more than 60000 hours; 2. high efficiency, energy saving and high luminous efficiency; 3. green environmental protection; 4. no strobes; 5. high power which is 150W-350W; 6. soft light and high color rendering index which is not less than 80; 7. instantaneous starting; 8. good shock resistance and suitability for anti-explosion places; and 9. small luminous decay which is only 8 percent and lumen maintenance which is only 92 percent in 2000 hours.

Description

Technical field: [0001] The invention relates to a lighting device, in particular to a high-power high-frequency electrodeless fluorescent lamp. Background technique: [0002] Currently commonly used lighting sources include incandescent lamps, tungsten-halogen lamps, high-pressure sodium lamps, high-pressure mercury lamps, metal halide lamps, ordinary straight fluorescent lamps and compact energy-saving lamps. While each light source has outstanding advantages, it inevitably has its own defects. For example: incandescent lamps have the advantages of high dominance, high power factor, and immediate start, but low luminous efficiency and short life. The lifespan of compact energy-saving lamps is relatively long, but the use of non-recyclable liquid mercury causes environmental pollution. Halogen tungsten lamps, high-pressure sodium lamps, high-pressure mercury lamps, and metal halide lamps all have defects such as high ultraviolet content, slow startup, cumbersome maintenan...
