Description
Technical field
The utility model relates to a kind of cold-cathode fluorescence lamp of high output light flux, the occasion that is used for the big luminous flux illumination of needs such as road lighting, tunnel illumination, billboard lighting, bridge, mansion, market, square, alternative existing high-pressure mercury lamp, high-pressure sodium lamp, electrodeless lamp, Metal halogen lamp, high-power hot cathode electricity-saving lamp etc.; Can be made into more that photochromic temperature is adjustable, light intensity is adjustable, the lamp of various different colors and variable colored lights etc.
Background technology
The high light flux light source that prior art is used for illuminations such as street lamp mainly contains low-pressure sodium lamp, high-pressure mercury lamp, high-pressure sodium lamp, electrodeless lamp, Metal halogen lamp etc.
The fluorescent tube photopic vision luminous efficiency of low-pressure sodium lamp is up to 180lm/W, but its colour rendering index is very low, now less use.
High-pressure mercury lamp has higher luminous efficiency, its fluorescent tube photopic vision luminous efficiency is 90-120lm/W, life-span can reach 25000 hours, it is the main force of present street lamp, Tunnel Lamp, this high-pressure mercury lamp of street lamp of China about 80%, but the colour rendering index of high-pressure mercury lamp is low, about 20-25 only, colour temperature is 2000-2400K, its main spectrum is positioned at gold-tinted, photopic vision/noctovision ratio is about 0.6, the only about 54-56lm/W of the scotopic luminous efficiency of fluorescent tube, and its object resolution is low, and promptly the object visibility is low, and is unfavorable to safety; Than the white light high-pressure mercury lamp of high color rendering index (CRI), lamp luminescence efficient 37-48lm/W only.
The about 50lm/W of high-pressure sodium lamp luminous efficiency, colour rendering index is about 45, and the life-span is short, less at present use.
Electrodeless light fixture have the life-span long, colour rendering index can be greater than 80, lamp system luminous efficiency (promptly comprising driver loss) is greater than advantages such as 60lm/W, problem is still waiting to solve but its cost height, electromagnetic interference be big etc.
The colour rendering index of Metal halogen lamp is 65-92, and lamp luminescence efficient is up to 72-95lm/W, and colour temperature is 3000-5600K, and its life-span was generally 6000-20000 hour; But its system's luminous efficiency is lower, when external power change to surpass ± 10%, its illuminant colour can change, the mounting means of its cold junction position, lamp, also can influence the illuminant colour and the life-span of lamp, reach 5-15 minute the start-up time of its lamp, restart and wait just can restart after 10-15 minute, lamp hole temperature is very high, sodium in the migration of quartz burner, can make light discoloration, quartz-metal reaction, quartzy venting etc. make the lamp lost of life, and cost is higher, at present also less use in street lamp, Tunnel Lamp etc.
The cold-cathode fluorescence lamp of prior art have the life-span reach 20,000-60,000 hours, switch life up to more than one hundred million times, system's luminous efficiency of lamp can reach more than the 55lm/W, colour rendering index is greater than advantages such as 80, be widely used in the liquid crystal display back illumination, also be used to make simultaneously 2-8W small-power helical type energy conserving lamp.But prior art thinks that the fluorescent tube internal diameter of optimal luminescent efficient of cold-cathode fluorescence lamp is 1.2-2.0mm, its external diameter is less than 2-4.1mm, if fluorescent tube, its luminous efficiency with big caliber will descend because of self-absorption aggravation, the fluorescent tube tube voltage drop of radiation photon and obviously descend, typical lamp current is 5mA, the length of this thin fluorescent tube is generally less than 1m, its single lamp power is little, output light flux is little, and for example single lamp power is less than 9W, and the luminous flux of single lamp is less than 500lm.Be difficult to make luminous flux up to several thousand 1m or higher high-power, high-luminous-efficiency illuminating lamp, be used for the occasion of the big luminous flux illumination of needs such as road lighting, tunnel illumination, billboard lighting, bridge, mansion, market, square.
In addition, neon light similar to cold-cathode fluorescence lamp, also belong to the gas glow discharge luminescent device.Neon light is with fluorescent tube, for example 8-16mm in extra heavy pipe footpath, bigger lamp works electric current, about 25-60mA for example, several thousand to 20,000 volts operating voltage work, lamp current density is little, the lamp works temperature is near room temperature, the only about 15-30lm/W of its white-light emitting efficient, and the life-span is about 3000 hours; Be mainly used in advertisement and show also there is not to make with neon light the high light flux efficient and long life illuminating lamp of usefulness such as street lamp, Tunnel Lamp so far.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, broken through cold-cathode fluorescence lamp and can only make the limitation of small light with tubule footpath fluorescent tube, also broken through the low limitation that can not be used for general lighting of neon light luminous efficiency, and provide a kind of high light flux cold cathode fluorescent lamp of high-luminous-efficiency, its output light flux can be up to 800-50000lm or higher, far above the screw type cold-cathode fluorescence lamp of prior art; Its lamp system luminous efficiency can be up to more than the 55lm/W, far above the neon light of prior art, also be higher than the screw type cold-cathode fluorescence lamp of prior art; Its life-span is also far above the neon light of prior art; But and high light flux cold cathode fluorescent lamp instantaneous starting of the present utility model, restart and also need not to wait for, but wide region continuous light tuning also more can be made into different photochromic temperature, photochromic temperature is adjustable, the lamp of various different colors and variable colored lights etc.
