The semi-conductor electricity light source is a kind of electric light source without filament, is a kind of luminescent device that is electric energy conversion directly luminous energy, is called light emitting diode, also referred to as semiconductor lamp, and the English LED that is called for short.
Semiconductor lighting is considered to the new energy-conserving light source of illumination of 21 century.LED is not only energy-conservation, also has that the life-span is long, volume is little, safety, environmental protection, characteristics such as non-maintaining, easy to control.LED can replace conventional light source to use in a lot of places, and the speed of LED replacement traditional lighting light source has been accelerated in the particularly appearance of great power LED, also makes LED become real in the large-area applications of room lighting.
Great power LED is a direction of industry future development, but great power LED has relatively high expectations to heat dissipation technology, and the power of LED module is larger, and the heat flow density of its chip is just higher.When the effect of radiator is bad, the temperature of LED chip sharply rises, and can produce very soon light decay, even damages LED chip.Only have the heat dissipation technology that solves great power LED, delay to greatest extent the light decay of LED, could promote widely the application of great power LED.
At present, the heat radiation of high-powered LED lamp much adopts the pole-shaped radiator of aluminium matter, need machined or mould molding to form, pole-shaped radiator generally comprises the heat conduction stem stem mediated and the function heat dissipating that is arranged on peripheral one, this pole-shaped radiator is because heat dispersion is constant, can only adapt to the use of the LED radiator of certain performance power, LED lamp heat radiation for the different capacity performance, the radiator of heat dispersion need to match, need die sinking again to make, especially in the situation that batch is little, increase production cost.
Summary of the invention
The invention reside in for current LED lamppost shape radiator and can only meet the deficiency that a kind of problem of LED lamp heat radiation of performance exists, and a kind of column LED radiator overcome the above problems is provided.
For achieving the above object, the present invention adopts following technical scheme:
A kind of column LED radiator, described radiator comprises the heat conduction stem stem of column, the periphery of heat conduction stem stem arranges some stem stem installed surfaces at length direction; Described radiator also comprises function heat dissipating, and described function heat dissipating arranges the heat radiation installed surface, and described function heat dissipating is close to detachable being arranged on the heat conduction stem stem by heat radiation installed surface and described stem stem installed surface.
Preferably, described function heat dissipating is sheet fin-shaped fin.
Preferably, described function heat dissipating is dendritic fin.
Preferably, on described heat conduction stem stem, be provided with the casket groove, function heat dissipating is provided with the casket piece, and the casket groove that the casket piece of function heat dissipating plugs on the heat conduction stem stem is close to stem stem installed surface and heat radiation installed surface.
Preferably, on described heat conduction stem stem, be provided with screw, function heat dissipating arranges perforation, and a bolt is close to stem stem installed surface and heat radiation installed surface by the perforation connecting screw hole.
Preferably, be provided with thermal conductance silica gel between described stem stem installed surface and heat radiation installed surface.
Beneficial effect of the present invention is: a kind of column LED radiator of the present invention, and radiator comprises the heat conduction stem stem of column, function heat dissipating is close to detachable being arranged on the heat conduction stem stem by heat radiation installed surface and described stem stem installed surface; What function heat dissipating was detachable is arranged on the heat conduction stem stem, the combination of the function heat dissipating by setting different numbers, form the LED radiator of different heat dispersions, adapt to the LED lamp heat radiation of different capacity performance, wide accommodation, without die sinking making again, especially adapt to small lot batch manufacture, reduce production costs.
