Description
Technical field
The present invention relates to a kind of light fixture, relating in particular to a kind of lamp socket that sees through derives the heat energy of LED bulb generation, and the heat conduction light fixture with plug type LED bulb being dispelled the heat.
Background technology
Modern tungsten lamp on 19, twentieth century handing-over succeeds in developing period, the filament that the illuminator of the inside has adopted tungsten filament to make, this material characteristics is that its fusing point is very high, at high temperature still can keep solid-state, so just can make bulb have certain life-span, filament can cannot not used with regard to blowing in the short time.In fact, the filament temperature of an incandescent lamp of lighting is up to 3000 ℃, and produced light radiation just because of red-hot filament, just makes electric light send bright radiance.And since then, the life of coming for people at night is no longer kind of an obstruction, has had cutting a conspicuous figure of incandescent lamp bulb, in all activities at night, no matter is work or in life, can continue very easily.The invention of incandescent lamp bulb can be said the lifestyle that changes greatly people, past more multiaspect of movable period is extended out, and then have more different all development.
And along with the progress of lighting, various lighting bulb is developed one by one, and in the lighting bulb of all electricity consumptions, the efficiency of incandescent lamp bulb is minimum, the electric energy consuming changes into the part of luminous energy and only has 12%-18%, energy conversion quite poor, remainder all scatters and disappears with the form of heat energy, and has slatterned most energy.Therefore, progress day by day along with science and technology, light emitting diode (Light Emitting Diode, LED) technology, day by day maturation with related peripheral integrated circuit Control Component and heat dissipation technology, make it apply diversification more, such as from lower powered power supply indicator and cell phone keyboard light source, to LED-backlit module and general illumination product, replace gradually the conventional light emitting source of tradition, short and hot in the life-span of incandescent lamp bulb, light emitting diode has power consumption low, not mercurous, the advantage such as halide and CO2 emissions are not low, for the environmental protection subject under discussion of day by day paying attention to for people, carbon reduction, reduce under the lateral thinking of mercury and halide use, national governments explicit order time limit forbid incandescent lamp and popularize light emitting diode in an all-round way.
And the characteristics of luminescence due to light emitting diode, it is the pattern of light source point, therefore more flexible in design, can make divergent light source and not dazzling bulb, also can do and concentrate a bit or the bulb of specific region, the color producing can be more bright-coloured bright, and white light LEDs luminous efficiency has reached 70lm/W at present, surpasses the 15lm/W of incandescent lamp bulb.But, the input power of light emitting diode only has 35% can convert light at present, all the other 65% is transformed into heat, these heats that produce, the arch-criminal who causes its luminous efficiency of light emitting diode to reduce, moreover, if the cooling mechanism of its whole device is not good, the heat energy that light emitting diode produces can cause heat energy accumulate on light emitting diode and cannot derive in real time, can make the lost of life of light emitting diode, in general, the life-span of LED lamp is more than 100000 hours, if but operating temperature is higher than 85 ℃, will greatly lower the life-span.
So comprise LED bulb interior, bulb in use, the temperature result that is inevitable that rises, heat radiation is the means of head it off, and the starting point of correlation technique can be placed on the radiating efficiency that how to promote each portion, makes heat accelerate to leave and obtain service life to promote.General scattering mechanism can adopt radiating fin, uses radiating fin to have preferably radiating effect, but this also makes the most of volume of bulb structure all by radiating fin, be accounted for, and light emitting source has only accounted for sub-fraction.In addition,, in the situation that the specification limits of conventional bulb does not change, in the bulb of same size, the volume of radiator structure part directly affects the luminous power of LED bulb.
Summary of the invention
