LED light source of the present invention, is mainly used in substituting existing ceiling lamp light source, to reaching easy for installation, energy-saving and emission-reduction, long service life, object that lighting effect is good.Consult shown in Fig. 7, when installation, first the light source in original lamp affixed to the ceiling is removed, then respectively heat sink 5 and binding post 14 are adsorbed on original mounting base by the first magnet 12 and the second magnet 14i, mounting base described in the present embodiment is iron plate, and therefore light source of the present invention can directly adsorb installation.Then original outside mains supply is penetrated in contact tube and lock and complete the work of changing light source.Finally cover lampshade and complete whole installment work.Whole installation process is very convenient quick.Adopt this Installation Modes, follow-up maintenance, replacing are all very convenient.
As everyone knows, LED light source is most important in installing is exactly heat radiation.Therefore in existing LED light source is installed, mainly contain two kinds of mounting means, a kind of is that LED light source is close to to be installed above to ensure best heat transfer effect, this mounting means, is generally applicable to indoor location, but in the time that light source works long hours, because contact area is limited, heat conduction speed is limited, also there is the fast not shortcoming of heat-transfer rate, cause LED light source heat to shed in time, affect the service life of LED light source thereby make LED light source central temperature increase; Another kind is that LED light source is suspended in midair away to be installed, to reach the object of heat radiation by cross-ventilation, this structure is generally applicable to outdoor mounted, but in the time that not convection current of outdoor air or convection current are weak, the radiating effect of LED light source is also just obviously affected, this mounting means is subject to the impact of external environment condition very much, and light fixture is unstable service life.And the present invention is in conjunction with the concrete condition of lamp affixed to the ceiling, by LED light source and to be installed, the spacing between heat sink 5 and mounting base remains on 2～10mm, forms stable thermal convection current space originally.Adopt this structure, not only ensure original area of dissipation, and by the effect of thermal convection current, using mounting base as additional cooler, between heat sink 5 and mounting base, carry out convection current heat conduction by the air in light fixture dexterously, make mounting base participate in the area of heat conduction, much larger than the area of heat sink 5, this just makes the area of dissipation of whole LED light fixture significantly expand, and radiating efficiency significantly improves, thereby significantly extended the service life of light fixture.In addition, the 2mm of spacing lower limit, can also ensure heat sink 5 back sides winding displacement easily.
Embodiment 3

Experimental example
Choose spacing between heat sink 5 and magnetic base plate 10 below and be each three of the light fixture of 2mm, 5mm, 8mm, 10mm, five kinds of specifications of 12mm, under equal environmental condition, measure light fixture lamp pearl, lamp plate, radiator and the temperature variations of magnetic base plate in 49 hours, and by openly as follows to maximum temperature, minimum temperature and the mean temperature of each specification in record.Because the temperature of light fixture can not change with regard to basicly stable after 48 hours, therefore only test the temperature conditions that can understand light fixture for 49 hours.Its test result is as follows:
Table 1 spacing is the light fixture of 12mm
Table 2 spacing is the light fixture of 2mm
Table 2 spacing is the light fixture of 5mm
Table 2 spacing is the light fixture of 8mm
Table 2 spacing is the light fixture of 10mm
From experiment, under square one, light fixture of the present invention and existing conventional lamp now than, lamp pearl temperature and substrate temperature are all lower, and the temperature of heat sink and magnetic base plate is generally all higher, especially magnetic base plate.The structure that this has just proved to adopt light fixture of the present invention, in the reasonable distance of heat sink and magnetic base plate, can effectively reduce the temperature of lamp interior, also proves that the cooling-down effect that under reasonable distance, thermal convection current brings is very significant simultaneously.
