Abstract
The utility model relates to the technical field of LED lighting, in particular to an LED streetlamp heat sink with multiple kinds of radiating performance. The LED streetlamp heat sink comprises an LED lamp installation area provided with a lower bottom and a waterproof radiating area on the upper side, wherein the waterproof radiating area comprises a heat sink installation face, a plurality of functional radiating pieces are tightly installed on the heat sink installation face in a detachable mode through a radiating installation face, and each functional radiating piece is detachably arranged on the heat sink installation face. The LED streetlamp heat sink with multiple kinds of radiating performance is formed by combination of the functional radiating pieces of different numbers, and is suitable for radiating of LED streetlamps with different kinds of power performance, is wide in application range, does not need repeated die opening for manufacturing, is especially suitable for small-lot production and reduces production cost.
Description
Technical field
The utility model relates to LED lighting technical field, refers in particular to a kind of LED road lamp cooling seat of many heat dispersions.
Background technology
Semi-conductor electricity light source is a kind of electric light source without filament, is a kind of luminescent device that is directly luminous energy electric energy conversion, 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, a feature 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.
As high-power LED street lamp, used and be promoted widely, 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.
Utility model content
The utility model is can only meet for current LED road lamp cooling seat 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 utility model 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 pedestal installed surface, and some function heat dissipatings are close to detachable being arranged on pedestal installed surface by 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 perforation connecting screw hole.
Preferably, between described pedestal installed surface and heat radiation installed surface, be provided with thermal conductance silica gel.
The beneficial effects of the utility model are: the LED road lamp cooling seat of a kind of many heat dispersions of the present utility model, 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 pedestal installed surface, and some function heat dissipatings are close to detachable being arranged on pedestal installed surface by heat radiation installed surface; Every detachable being arranged on pedestal installed surface of function heat dissipating, by setting the combination of the function heat dissipating of different numbers, form the LED road lamp cooling seat of different heat dispersions, the LED road lamp cooling that adapts to different capacity performance, wide accommodation, without die sinking making again, especially adapt to small lot batch manufacture, reduce production costs.

The specific embodiment
Below in conjunction with accompanying drawing, 1-4 is further elaborated the utility model:
LED road lamp cooling seat of the present utility model, in detachable being arranged on pedestal installed surface 3 of every function heat dissipating 4, by set different numbers function heat dissipating 4 combination (as shown in Figure 2, for the road lamp cooling seat of part function heat dissipating 4 is set), or function heat dissipating 4 is selected the heat sink material of different performance, form the LED road lamp cooling seat of different heat dispersions, the LED road lamp cooling that adapts to different capacity performance, wide accommodation, without die sinking making again, especially adapt to small lot batch manufacture, reduce production costs.
The above embodiment, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, the equivalence of doing according to structure, feature and principle described in the utility model claim therefore all changes or modifies, and all should be included in the utility model patent claim.
