Description
Technical field
The utility model relates to a kind of improved electrodeless lamp.In addition, the utility model also relates to the luminaire for road and street lighting that this electrodeless lamp is installed.
Background technology
Street lamp is the important component part of city illumination, and traditional street lamp often adopts high-pressure sodium lamp as light source.But shortcomings such as that high-pressure sodium lamp exist to start is slow, stroboscopic light decay, power loss are big, temperature rise, noise is big, color rendering is low, the life-span is short have caused the maintenance cost height, and energy waste is bigger.Therefore, development of new is efficient, energy-conservation, the life-span is long, color rendering index is high, the street lamp of environmental protection has a crucial meaning to city illumination is energy-conservation.
By contrast, HF lamp without electrodes is with its overlength useful life more than 60,000 hours, and is energy-saving and cost-reducing, the power saving environmental protection, high light efficiency, high-color rendering, no stroboscopic, euphorosia safety, but the moment startup is restarted, advantage in the majority such as non-maintaining can replace other high energy consumption fully, and the electric light source in low life-span is applied to places such as various indoor, open airs.HF lamp without electrodes does not have the filament and the electrode of conventional light source, mainly is made up of radio-frequency generator, power coupler and glass cell-shell three parts, by way of electromagnetic induction energy is coupled in the bulb.Be filled with an amount of special gas in the bulb, high-frequency energy makes it ionization or excites, and the atom after exciting sends ultraviolet photon when higher energy level is returned ground state, and ultraviolet photon excites the fluorescent material of inner wall to produce visible light.
At present, electrodeless lamp uses amalgam as ionization material more.Amalgam is arranged in the short tube of cell-shell bottom, be connected with the aluminium seat of coupler, in case the lamp steady operation it mercury atom just is provided.But the temperature at amalgam position can have very big influence to the luminous flux of lamp, experiment showed, the amalgam luminous flux that all can reduce lamp too high or too low for temperature, thereby reduces light efficiency, does not reach purpose of energy saving.Therefore, when guaranteeing that electrodeless lamp is worked, amalgam position temperature is just extremely important in certain stability range.
Portioned product reduces this position temperature by the method that increases fin at foam holder position now, but since fin directly and reflector and coupler aluminium seated connection touch, when temperature reaches certain balance point, just can't effectively implement heat radiation again, so radiating effect is limited.
State Intellectual Property Office announced on June 13rd, 2007, number of patent application is 200510102395.7, name is called in the application for a patent for invention file of " HF lamp without electrodes ", disclose a kind of HF lamp without electrodes, having comprised: high-frequency electrical component (1), electrodless discharge bulb (3) and place power coupler (2) in its cavity (31); Tube-shape magnetic core (22) in the middle of the top of passive heat-conducting metal rod and the power coupler (2) is pegged graft; The heat-conducting metal rod adopts inside to have the heat pipe (21) of capillary structure (211), and the sealing tube chamber of this heat pipe (21) is filled with hydraulic fluid, and its lower end connects a radiating block (5); The heat that produces during power coupler (2) work makes the hydraulic fluid vaporization on heat pipe (21) top and flows to heat pipe (21) bottom and pass through radiating block (5) to extraneous release heat, be condensed into liquid state subsequently and be back to heat pipe (21) top by capillary structure (211) absorption again, the heat that described power coupler (2) constantly produces is taken away in the above-mentioned circulation of the interior hydraulic fluid of heat pipe (21) quickly and efficiently.Adopt technical scheme of the present invention to improve the radiating efficiency of HF lamp without electrodes greatly, so will obtain the useful life of HF lamp without electrodes prolonging, and make manufacturing high-power high-frequency electrodeless lamp become possibility.
In this scheme, the electrodless discharge bulb is in real work, often radiating block 5 and high-frequency electrical component 1 are fixed under the environment of a relative sealing or semitight (as the light fixture casing), simultaneously, because the requirement of fit dimension, the size of discharge bulb bottom radiating block 5 limits to some extent, when the heat of discharge lamp bubble internal delivery exceeds the heat that radiating block 5 disperses and reaches heat balance, separately by the surface radiating of radiating block 5 itself, radiating effect will be had a greatly reduced quality, and its scheme exists on radiating efficiency uses limitation.Can't be suitable for powerful electrodeless lamp, exothermic temperature can not guarantee to meet the amalgam position and reach temperature at the polishing flux.
