Description
Technical field
The present invention relates to a kind of electricity-saving lamp, particularly, relate to a kind of vacuum electronic impact fluorescent energy-saving lamp.
Background technology
Global energy crisis has appearred in 20 century 70s, and the sense of urgency of energy savings makes many companies be devoted to energy-conserving light source.In order to replace conventional incandescent, development in recent years goes out fluorescent tube, ballast, starter is combined, be used in conjunction with the modified form fluorescent lamp bulb of incandescent lamp holder, be called electricity-saving lamp, be called again self-ballasted fluorescent lamp, low inflation fluorescent lamp, can in the situation that not change light fitting base, directly replace incandescent lamp and use.Fluorescent lamp belongs to a kind of of arc lamp, and it uses electric power to excite mercury vapor in argon or neon, forms plasma and sends short wave ultraviolet, and after ultraviolet ray is absorbed by phosphorus matter, phosphorus can send visible light with illumination, and the mode of sending like this visible ray belongs to fluorescence.Different from incandescent lamp, the inflation fluorescent tube must be provided with ballast, coordinates with starter and produces the instantaneous pressure that allows gas that ionization occurs.Fluorescent material on the fluorescent lamp tube wall is luminous under the bombardment of photon, its photochromic daylight that approaches, and by adding rare earth element, luminous efficiency is improved, under Same Efficieney, be the brightness of 6 times of ordinary incandescent lamps.Can obtain the radiance of 60 watts with the electricity-saving lamp of 10 watts, save the electric power of 50 watts.
But electricity-saving lamp has following shortcomings:
1. be different from incandescent lamp, electricity-saving lamp in use, can produce electromagnetic wave and microwave slightly.The electromagnetic intensity that the electricity-saving lamp of each watt produces is about 4.67 milligauss, with the about 3.3 μ W/cm of microwave
2.
Mercurous, ultraviolet leakage may be arranged; Inflation, complex manufacturing technology and poor stability, many Chinese workmans are mercury poisoning because manufacture electricity-saving lamp.
3. have the light decay problem, using luminosity of a specified duration can be lower than new product.
4. the unit price of electricity-saving lamp, higher than incandescent lamp, must just can save money in situation about often using.
5. the electricity-saving lamp great majority can't light modulation, is not suitable for the light fixture of adjustable light brightness.
6. the place of the frequent switch of inapplicable needs, better with LED or CCFL illumination (CCFL electricity-saving lamp) in these places.
7. color rendering is lower: incandescent lamp and Halogen lamp LED color rendering are 100, and performance is perfect; The electricity-saving lamp color rendering is mostly between 80 to 90, and the electricity-saving lamp color rendering is the highest to be only had over 90; If more high color rendering, can choose the most perfect T8 fluorescent tube, color rendering reaches 98 to 99.Low light source of drilling look not only sees that the thing color is plain, also harmful to health and eyesight.
In addition, because startup, filament pre-heating, glow discharge, the arc light of fluorescent tube is illuminated to, to proceed to steady operation be to complete in same circuit element, it is very difficult wanting the mutual adaptation of the parameter of element, the glow voltage of the preheating of needs consideration illuminating lamp tube filament, restriction preheat curent, restriction lamp tube ends, consider that again arc light punctures, current limliting is lighted steady operation, be difficult to carry out accurate adaptation under dynamic condition.So the low inflation fluorescent lamp within a very long time due to the problems such as discreteness of each element, cause lamp of low quality, cost performance is lower, the energy-conservation money that do not save of Market reaction.Energy-conserving light source develops into today, because the low inflation power-saving technology lacks improvement all the time, by other energy-conserving light source technology, is substituted gradually.
Except electricity-saving lamp, the most powerful competitor is high-intensity gas discharge lamp (HID) and light-emitting diode (LED) solid-state illumination technology at present.
The electric light that high intensity discharge (HID) bulb has comprised following these kinds: mercury vapor lamp, metal-halide lamp (HQI), high-pressure sodium lamp, low-pressure sodium lamp, high-pressure mercury-vapor lamp, and more rare short arc xenon lamp.The light-emitting component of these bulb kinds is one and is placed in stable arc discharger in high temperature resistant fluorescent tube (arc-tube), and has over 3W/cm
2luminous power.The same with fluorescent lamp, the HID lamp needs a stabilizer to trigger and maintain inner electric arc, and the mode that triggers electric arc is had nothing in common with each other: mercury vapor lamp and some metal-halide lamp help start in a main electrode side with the 3rd electrode usually therein, and other lamp kinds are used the mode of high-voltage pulse usually.When the HID lamp usually is applied in large area region and needs high-quality light, or during for specific (special) requirements such as energy efficiency, light source density.These places comprise gymnasium, large-area public domain, warehouse, cinema, outdoor activities zone, road, parking lot or tunnel.The major defect of high intensity discharge (HID) bulb is comparatively heavy and on the high side, and the home lighting field is universal uses because its safety issue is not adapted at.
Light-emitting diode (LED) is the luminous semi-conductor electricity sub-element of a kind of energy.This electronic component occurred as far back as 1962, can only send in early days the ruddiness of low luminosity, develop afterwards other monochromatic versions, the light that can send has even to this day spreaded all over visible ray, infrared ray and ultraviolet ray, luminosity is also brought up to suitable luminosity, and purposes is also by the beginning as indicator light, display panel etc.; Along with the appearance of white light emitting diode, continuous gradually being developed to is used as illumination, has advantages of that efficiency is high, the life-span long, the conventional light source such as high, the high reliability of cracky, switching speed is not too late.But when the luminous intensity of LED reaches to the words that are enough to be used in room lighting, during especially as watt level lighting source, the extremely unreasonable level of cost meeting height, and the volume ratio of LED is huger, heat dissipation problem can't rationally solve, need in addition attached heat sinks, the ballast of hundreds and thousands of times, cost is very high, is that universal major reason is failed in current LED illumination.

Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention:
Embodiment 1: as shown in Figure 1 to Figure 3, vacuum electronic impact fluorescent energy-saving lamp in the present embodiment, it on its external overall, is a transparent glass body 1, transparent glass body 1 forms a fluorescent tube, the fluorescent tube mouth of pipe sets solid welding negative electrode 2, 4 three electrodes of anode 3 and third electrode, be provided with electron emitter and Electron absorption body in transparent glass body 1, transparent glass body 1 seals the space 5 of bleeding of a near vacuum with air tight manner, transparent glass body 1 inwall inboard is provided with phosphor powder layer 6, electron emitter the two poles of the earth connect respectively negative electrode 2 and third electrode 4, Electron absorption body jointed anode 3 and be distributed in the inboard of transparent glass body 1 inwall, when three electrodes of vacuum electronic impact fluorescent energy-saving lamp and external circuit are connected and are powered, just can carry out luminous lighting work.
The space 5 of bleeding in transparent glass body 1 can guarantee that electronics has free passage, and by vacuum pump, is evacuated to 10
-4the pressure of torr, can guarantee normal operation, 10
