Description

Miniature built-in radiator high power semi-conductor lamp

Technical field

The utility model relates to a kind of lamp, is specifically related to a kind of miniature built-in radiator high power semi-conductor lamp that has heat abstractor that is used for places such as street, square, station, harbour.

Background technology

At present, general semiconductor (LED) lighting generally includes pedestal, is located at semiconductor light emitting body (LED), the lamp socket on control power supply, operated by rotary motion and pedestal or the lamp housing and the lampshade that is covered with light source (illuminator) on the pedestal, borrow the luminous light fixture that makes of semiconductor light emitting body (LED) to produce enough illuminations, help to promote visual line of sight and form the caution effect.

But when semiconductor light emitting body (LED) is luminous, temperature and heat energy are also with rising service time, can form high temperature and high heat during therefore long-time the illumination, and lampshade normally becomes intimate air-tight state with lamp socket, therefore heat radiation is very slow under good cross-ventilation of shortage or conductive medium, make the lamp interior continuous high temperature, increase the light decay of semiconductor light emitting body (LED), reduce service life, simultaneously, for light-weight design, also to guarantee minimumguarantee heat radiation requirement, general lampshade and lamp socket major part are all used the alloy aluminum material, and light fixture outward appearance volume is less, in the expressway, the illumination of places such as major urban arterial highway is neither attractive in appearance less because of style again, selection face is less, therefore high temperature and high heat can influences the service life of light fixture integral body, and occurring the light decay quickening simultaneously influences illuminating effect, and high temperature also damages circuit easily and breaks down.Above-mentioned semiconductor light emitting body (LED) illuminating lamp, be opened on lampshade and the dust cover heat abstractor, though can solving the heat of part, this structure gathers, but very easily deposit the dust foreign material, radiating effect is limited, and existing illuminating lamp, often heat abstractor is located at outside the lampshade, body weight is bigger, and semiconductor light emitting body (LED) is changed inconvenience, and cost is bigger.

Summary of the invention

Deficiency at the prior art existence, technical problem to be solved in the utility model is, provide a kind of simple in structure, with low cost, change convenient, improve the illuminating lamp radiating efficiency, prolong the lamp miniature built-in radiator high power semi-conductor lamp in service life.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of miniature built-in radiator high power semi-conductor lamp, comprise lamp socket, lampshade, integrated form chip, described lampshade and lamp socket surround into an enclosure space, described lamp socket upper end is provided with a heat pipe that leads to this enclosure space with heat absorbing end, in the described heat pipe heat-conducting medium is set, is provided for strengthening the fin of radiating effect at the radiating end of heat pipe.

Above-mentioned miniature built-in radiator high power semi-conductor lamp, described heat pipe be arranged five in parallel, is provided with an inlet that is used to annotate heat-conducting medium in the heat absorbing end of heat pipe, and described inlet is provided with end cap.

Above-mentioned miniature built-in radiator high power semi-conductor lamp, described heat pipe heat absorbing end is parallel with lamp socket, and radiating end is to the bending of lampshade direction and rely on lampshade.

Above-mentioned miniature built-in radiator high power semi-conductor lamp, it is characterized in that: described heat-conducting medium is conduction oil or water.The advantage of the utility model miniature built-in radiator high power semi-conductor lamp is: the utility model is by the heat pipe in the enclosure space that stretches into lampshade and lamp socket composition that is provided with, the high heat of high temperature that can in time semiconductor light emitting body (integrated LED chip) be produced conducts, dress heat-conducting medium in the heat pipe, fin in the installation of heat pipe radiating end, improved radiating effect greatly, be applied in the existing traditional lighting light fixture reducing energy consumption, under the prerequisite of not changing lamp body, change built-in light source electrical equipment, convenient and swift with miniature built-in radiator high power semi-conductor lamp replacement high-pressure mercury lamp or metal halide lamp illumination, energy-saving effect is (this alternative 250W high-pressure mercury lamp of 120W miniature built-in radiator high power semi-conductor lamp or metal halide lamp, alternative 400W high-pressure mercury lamp of 160W miniature built-in radiator high power semi-conductor lamp or metal halide lamp) obviously.The utility model miniature built-in radiator high power semi-conductor lamp, reasonable in design, with low cost, practical, be fit to implement industrialization production as early as possible and widely popularize application.
