Abstract
Provided is a high-frequency electrodeless fluorescent lamp. A power coupler is disposed in a central cavity in a housing and is connected with a high-frequency generator. A luminescent coating is coated on the interior surface of the housing. Main amalgam is arranged at the bottom of the housing and auxiliary amalgam is arranged on the outer side of the central cavity. The advantages are that: firstly, the high-frequency electrodeless fluorescent lamp has the super-long service life that can last as long as more than 60 thousand hours; secondly, the lamp is highly efficient and energy-saving and is high in luminescence efficiency; thirdly, the lamp is green and environment-friendly; fourth, the lamp is strobe-free; fifth, the lamp exhibits high power ranging from 150W to 350W; sixth, light emitted by the lamp is soft and mild, and a color rendering index is equal to and greater than 80; seventh, the lamp can be started instantly; eighth, the lamp exhibits a good shockproof property and is suitable for an explosion-proof place; and ninth, the lamp is low in light decay, and a luminous flux maintenance rate is only 92% and the light decay is only 8% within 2000 hours.
Description
Technical field:
The utility model relates to a kind of lighting apparatus, particularly a kind of high-frequency electrodeless fluorescent lamp.
Background technology:
Present normally used lighting source has incandescent lamp, tungsten halogen lamp, high-pressure sodium lamp, high-pressure mercury lamp, metal halide lamp, normal straight tube fluorescent lamp and compact type energy-saving lamp.Every kind of light source inevitable self defective when having outstanding advantages.For example: the advantage that incandescent lamp has high dominant, high power factor, starts immediately, but light efficiency is low, the life-span is short.The compact type energy-saving lamp life-span extends relatively, but has used expendable liquid mercury, causes environmental pollution.All there are the defectives such as ultraviolet content is high, startup is slow, maintenance is loaded down with trivial details, color rendering is low, useful life is short, power factor (PF) is low in tungsten halogen lamp, high-pressure sodium lamp, high-pressure mercury lamp, metal halide lamp.And these lighting sources have all used filament or electrode, and the splash effect of filament or electrode limits the key factor of light source life just.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of high-frequency electrodeless fluorescent lamp is provided, and long service life, the power of this fluorescent lamp is large, color rendering good, without stroboscopic.
The technical solution of the utility model is: a kind of high-frequency electrodeless fluorescent lamp, comprise housing, and it is characterized in that: the center cavity in housing is in-built power coupler, and power coupler is connected with radio-frequency generator; The inner surface of housing scribbles luminescent coating; In the bottom of housing, main amalgam is housed, in the outside of center cavity, secondary amalgam is housed.
Above-mentioned luminescent coating is the three primary colors fluorescent powder layer.
The utility model is compared with conventional fluorescent has following advantage and good effect:
1, extra long life.Owing to adopting the work of high-frequency electromagnetic induction coupled modes, cancelled traditional filament and electrode, the life-span reached more than 60,000 hours.
2, energy-efficient, luminous efficiency is high, more than can reaching 60Lm/W, has extremely low operating cost and maintenance cost.
3, environmental protection.Due to the solid-state amalgam of employing and crown glass, so environmental protection.
4, without stroboscopic, operating frequency is 2.65MHz, and is international.And conventional fluorescent employing filament heating operating frequency is tens KHz.
5, power is large.Conventional fluorescent is due to the limitation of excitation principle and technique manufacturing, and power is less, is generally tens W.And the utility model adopts the HF lamp without electrodes of single coupler, power maximum to be generally the 150W left and right, and employing assembly type high-frequency electrodeless fluorescent lamp power can be greater than 350W.
6, because luminescent coating is the three primary colors fluorescent powder layer, therefore luminous soft, color rendering index is high 〉=and 80.
7, instantaneous starting starts and restarts the time all less than 0.5 second, namely opens namely brightly, is fit to the illumination of various environment and place.
8, shockproof properties is good, is suitable for explosion-proof place.
9, light decay is little, and lux maintenance was only 92% in 2000 hours, and light decay is only 8%.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in the figure: a kind of high-frequency electrodeless fluorescent lamp, the center cavity 2 in bulb housing 1 is in-built power coupler 3, and power coupler is connected with radio-frequency generator; The inner surface of bulb shell scribbles luminescent coating 4; Main amalgam 5 is housed in the bottom of bulb, secondary amalgam 6 is housed in the outside of center cavity.Above-mentioned luminescent coating is the three primary colors fluorescent powder layer.
Operation principle of the present utility model is: the high-frequency electromagnetic field energy is coupled in bulb with induction mode, make the breakdown formation plasma of gas in bulb, when the plasma excited atom is returned to ground state, give off the ultraviolet ray of 254nm, in bulb, fluorescent material is subject to ultraviolet ray excited and sends visible light.
