Abstract
The utility model provides a radiating structure of streetlamp, includes the lamp body, the lamp body lateral wall is provided with a plurality of formation and seals cyclic annular heat dissipation circle, seal cyclic annular radial be the level to, the lamp body with the heat dissipation circle is connected through the heat -conducting metal. The utility model discloses avoid the easy deposition of top heat radiation structure of traditional lamps and lanterns, and then influenced the problem of radiating effect.
Description
Technical field
The invention relates to a kind of road lamp radiating structure, belongs to lighting technical field.
Background technology
LED is as energy-conserving and environment-protective, the light source of green health, and by promotion and application widely, but LED is generated heat relatively
Height, the most powerful application, heat dissipation problem directly affects the service life of LED light source equipment, limits LED light
The popularization and application in source.
The street lamp product that most enterprises manufacture is all based on using aluminum alloy materials to do shell and LED lamp bead
The mode being directly connected to is dispelled the heat.LED street lamp shell is a radiator, and heat produced by major part lamp bead is slow
Come out.This shell is as radiator, and effect is undesirable, in rugged environment, dust accretions heat radiation shell in,
Heat is caused to dissipate.
Notification number is that the patent of CN102418912 discloses a kind of for LED road lamp cooling module, and prize heat conducts extremely
The side of module, it is to avoid the problem of conventional products end face radiator easy dust stratification impact heat radiation, and employ heat pipe, but this module
Due to the use of heat pipe, cause relatively costly, and radiating effect still suffers from gap compared with the heat radiation of traditional end face.
Summary of the invention
The invention is for solving prior art problem, it is provided that a kind of more preferable radiator structure of radiating effect.
The technical scheme of the invention is:
A kind of road lamp radiating structure, including lamp body, described lamp body sidewall is provided with the cooling ring of some formation closed circulars,
The radial direction of described closed circular be level to；Described lamp body is connected by heat-conducting metal with described cooling ring.
As preferably, described lamp body includes that light-source chamber and power source cavity, described cooling ring are arranged at the outside of described light-source chamber
Wall.
As preferably, the lateral wall of all described cooling rings is connected with each other, and forms a shape and approximates phase with described light-source chamber
The same annular outer ring that lateral surface is almost plane.
As preferably, described annular outer ring is connected with described light-source chamber by some dowels, outside described light-source chamber
Side, the medial surface of described annular outer ring and described dowel form described cooling ring.
As preferably, described light-source chamber top is provided with several reinforcements.
As preferably, the lateral wall of all described cooling rings is connected with each other, and forms a shape and approximates phase with described light-source chamber
Same annular outer ring, described annular outer ring is connected with described light-source chamber by some dowels；Described reinforcement and described company
Connect muscle to be connected.
With the technical scheme difference of the patent that notification number is CN102418912, the invention is that this patent have employed out
Put the radiator structure of formula fin shape, high due to fin temperature in theory, really have and the possibility of ambient air formation convection current.But
Street lamp is installed on open air mostly, is especially installed on the lamp stand top with certain altitude, does not has stable air ambient, its knot
Structure is again open, therefore can be affected by wind, and when the wind of horizontal direction is to module, the windward side of module forms height
Nip, the convection current of hot-air can be partial under the influence of wind, and again due to the stop of fin, these heat that originally can form convection current are empty
Gas can be partially formed the most relatively independent high-temperature region between adjacent fin, and can be because of the whirlpool of wind at the lee face of module
Flowing and form low-pressure area, the minimizing of air can reduce the speed of heat exchange, reduces radiating effect on the whole.
And the invention have employed the cooling ring structure of closing, when horizontal direction crosswind blows, do not interfere with cooling ring
Interior convection current, only can form, to hot-air, effect of bleeding on cooling ring top, in cooling ring bottom, cold air is formed acceleration and mends
Gas effect, radiating effect has had great lifting.And the lateral surface of almost plane also has blocking effect to crosswind, can by level to
Wind be directed on the upper side or on the lower side to, improve the convection effects in cooling ring further, improve rate of heat dissipation.Dowel structure has
Effect optimizes heat conduction stream, improves heat of light source and conducts the heat-conducting effect to cooling ring.
In sum, the invention has the advantage that
1, the easy dust stratification of top radiating structure of conventional lamp, and then the problem affecting radiating effect are avoided；
2, the radiating effect of light fixture it is effectively improved.
