Wherein substrate is pottery, aluminium base or copper base, improves thermal conductivity.
In order to LED light source module 4 is formed effective heat-dissipating space, and this heat-dissipating space is symmetrical, evenly, all radiating tubes surround class cylinder, and light source module is in center.
In order to improve heat and effective exchange of cool ambient air in radiating tube, leaving space between adjacent two radiating tubes, improving the free convection of air, improving heat-conducting effect.
In order to form uniform natural convection air passage, form uniform heat transfer effect in LED lamp housing, when air outlet is multiple, all air outlets are uniformly distributed, and the hot-air after heat exchange can evenly be discharged.
The same, when air inlet is multiple, all air inlets are uniformly distributed, and treat that the cold air of heat exchange can evenly enter, and arrive each position of housing.
Superconductive medium of the present invention is can the superconductive liquid of phase transformation, by the gas phase interconvertibility of superconductive liquid, and the gravitational effects of itself, realize the quick conduction of superconductive liquid, and the flowing in radiating tube, and then improve radiating effect.
In order to better install this LED lamp, change each assembly of lamp interior, housing comprises the upper shell 2 and lower house 9 that are screwed, is taken apart the housing of LED lamp by screw.
During installation, it is fixed LED light source module 4, LED light source module plastic parts 5 and is fixed on radiator 3 by M2.5X6 countersunk head screw 6, Heat Conduction Material is scribbled between LED light source module 4 and radiator 3, optics reflector 7 being fixed on LED light source module fixes on plastic parts 5 in corresponding notch, coordinates optics pressure ring 8 by screw thread by locked for optics reflector 7; By M3X10 countersunk head screw 1, radiator 3 is fixed on the upper shell 2 of light fixture; By M3X10 countersunk head screw 1, the upper shell 2 of light fixture and lower house 9 are fixed.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
