Description
Technical field
The present invention relates to the LED lighting technical field, refer in particular to a kind of LED road lamp cooling seat of many heat dispersions.
Background technology
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.
Used widely and be promoted as the high-power LED street lamp, along with different lighting demands, power also has different requirements, and heat dispersion also there are differences; The radiating seat of current LED street lamp, radiating seat comprises the LED lamp installing zone go to the bottom and the waterproof cooling district of upside is set, function heat dissipating and the radiating seat in waterproof cooling district are integrated, this pole-shaped radiator, because heat dispersion is constant, can only adapt to the use of the LED street lamp of certain performance power, for the LED road lamp cooling of 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 road lamp cooling seat and can only meet the deficiency that a kind of problem of LED road lamp cooling of performance exists, and the LED road lamp cooling seat of a kind of many heat dispersions that overcome the above problems is provided.
For achieving the above object, the present invention adopts following technical scheme:
A kind of LED road lamp cooling seat of many heat dispersions, described road lamp cooling seat comprises the LED lamp installing zone go to the bottom and the waterproof cooling district of upside is set, described waterproof cooling district comprises the pedestal installed surface, and some function heat dissipatings are close to detachable being arranged on the pedestal installed surface by the heat radiation installed surface.
Preferably, described function heat dissipating is sheet fin-shaped fin.
Preferably, described function heat dissipating is post fin-shaped fin.
Preferably, on described pedestal installed surface, be provided with screw, function heat dissipating arranges perforation, and a bolt makes pedestal installed surface and heat radiation installed surface be close to setting by the perforation connecting screw hole.
Preferably, be provided with thermal conductance silica gel between described pedestal installed surface and heat radiation installed surface.
Beneficial effect of the present invention is: the LED road lamp cooling seat of a kind of many heat dispersions of the present invention, described road lamp cooling seat comprises the LED lamp installing zone go to the bottom and the waterproof cooling district of upside is set, described waterproof cooling district comprises the pedestal installed surface, and some function heat dissipatings are close to detachable being arranged on the pedestal installed surface by the heat radiation installed surface; Every detachable being arranged on the pedestal installed surface of function heat dissipating, the combination of the function heat dissipating by setting different numbers, form the LED road lamp cooling seat of different heat dispersions, the LED road lamp cooling that adapts to the different capacity performance, wide accommodation, without die sinking making again, especially adapt to small lot batch manufacture, reduce production costs.
