Description
Technical field
The utility model relates to a kind of bulb heat radiation structure, relates in particular to a kind of combined type bulb radiator structure that need not use screw to fix and can closely combine.
Background technology
As light emitting source, it is simple in structure with tungsten filament for conventional bulb, and installing and replacing is all quite convenient.The structure of osram lamp is generally in the affixed adapter of the tail end of spherical shape lampshade, and this adapter has screw thread and can supply to screw in the general tube face.When turn-on power, can make the tungsten filament heating that is arranged in the lampshade luminous, light penetration lampshade and shine the external world, and reach illumination purposes.Yet produce at osram lamp during the running of illuminating ray, also produce great amount of heat energy simultaneously, therefore quite power consumption, waste energy, and tungsten filament burns easily and make the service life of osram lamp of short duration.
(light emitting diode LED) is a kind of solid state light emitter that converts electrical energy into luminous energy to light emitting diode, utilizes the epitaxial growth technology to be made with semi-conducting material technology.It has that volume is little, driving voltage is low, reaction rate is fast, shatter-proof, the life-span long and meet characteristic such as environmental protection.And constantly development is with progressive along with science and technology, and its luminous efficiency promoted for promptly having continued since coming out from nineteen sixty, and (usefulness is about 10～20lm/W), has placed oneself above also at present that (usefulness is about on 60～80lm/W) at fluorescent tube not only to have surmounted osram lamp already.Because constantly in progress, estimating, the correlation technique of LED will be expected to reach the level of 100lm/W in recent years.Because LED become the focus that new generation solid state light emitter attracts most attention, electronic component more and more requires compactization at present, makes the bulb type led lamp replace osram lamp gradually and becomes the lighting device of a large amount of and extensive use.And along with the universal use of red signal lamp used by rail workers, street lamp, household illuminating lamp, car light, advertising lamp etc., it is irresistible that LED becomes the main flow trend of illumination market.
Yet the heat that the light emitting diode that power, brightness are big more or its module produce is big more, and in the less relatively led lamp of volume, is difficult to distribute.So light emitting diode remains at big heat dissipation technology bottleneck, this also is high-power at present, the most difficult key point that breaks through of the high brightness LED lamp tool marketization.The general heat sink conception of industry is provided with a radiator in this light fixture at present, heat is dispersed in the surrounding air with the mode that the free convection air contacts through this spreader surface.So the radiating requirements of led lamp that satisfies high power, high brightness just must provide area of dissipation very big radiator so that it can operate as normal prevent light decay.The common like this radiator shared volume in light fixture that can cause is big, and overall lamp is specifically long-pending also big, makes this fitting structure volume be difficult to extensive use in room lighting greatly.
For solving the problem of above-mentioned heat radiation; The novel patent of TaiWan, China discloses a kind of radiator structure of LED lamp for M343768 number; Dispensing hole one position periphery in shell body is provided with a delineation position flange, makes and forms a containing hole in this locating flange, fits with first board and second board respectively in the containing hole both sides; First board provides the control chip setting; Second board provides the setting of LED lamp, is arranged in the containing hole this containing hole both sides and by this first board, the sealing of this second board with heat-conducting liquid or thermal grease; Promote the contact area of heat radiation by this, to increase the effect of heat radiation.
Yet; The radiator structure of above-mentioned LED lamp is to assemble this shell body, this first board and this second board with the mode of screw and screw location, and in the time of on technology, after die sinking, need increase has the program that wears screw; And when assembling; It is inappropriate when screw wears screw, to exert oneself, and causes the shell body be full of cracks, damages, thereby reduce the problem of technology yield.
