Abstract
A street lamp cooling structure comprises a lamp body; the side wall of the lamp body is provided with a plurality of cooling rings forming a closed ring shape; the radial direction of the closed ring shape is the horizontal direction; and the lamp body is connected with the cooling rings through heat conductive metal. The street lamp cooling structure avoids the problems that a top cooling structure of a traditional lamp is prone to dust accumulation, and accordingly the cooling effect is affected.
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, and the light source of green health, by promotion and application widely, but LED heating is higher, especially powerful application, heat dissipation problem directly affects the service life of LED light source equipment, limits applying of LED light source.
The street lamp product that current most enterprise manufactures is all do shell based on use aluminum alloy materials and dispel the heat with the mode that LED lamp bead is directly connected.LED street lamp shell is a radiator, slow the coming out of heat that most of lamp pearl produces.This shell is as radiator, and effect is undesirable, and in rugged environment, dust accretions, in the shell of heat radiation, causes heat to dissipate.
Notification number is that patent discloses of CN102418912 is a kind of for LED street lamp heat radiation module, prize heat conduction is to the side of module, avoid the problem of conventional products end face radiator easy dust stratification impact heat radiation, and employ heat pipe, but this module is due to the use of heat pipe, cause cost higher, and radiating effect dispel the heat with traditional end face compared with still there is gap.
Summary of the invention
The invention, for solving prior art problem, provides a kind of radiating effect better radiator structure.
The technical scheme of the invention is:
A kind of road lamp radiating structure, comprise 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 comprises light-source chamber and power source cavity, and described cooling ring is arranged at the lateral wall of described light-source chamber.
As preferably, the lateral wall of all described cooling rings is interconnected, and forms a shape and the approximately uniform lateral surface of described light-source chamber is the annular outer ring of almost plane.
As preferably, described annular outer ring is connected with described light-source chamber by some dowels, and the lateral surface of described light-source chamber, 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 interconnected, and form a shape and the approximately uniform annular outer ring of described light-source chamber, described annular outer ring is connected with described light-source chamber by some dowels; Described reinforcement is connected with described dowel.
The invention and notification number are that the technical scheme of the patent of CN102418912 is distinguished and is that this patent have employed the radiator structure of open fin shape, in theory because fin temperature is high, really have to form convection current with ambient air may.But street lamp is installed on open air mostly, especially the lamp stand top with certain altitude is installed on, there is no stable air ambient, its structure is again open, therefore the impact of wind can be subject to, when the wind of horizontal direction is to module, the formation higher-pressure region, windward side of module, being partial under the influence of wind failing to be convened for lack of a quorum of hot-air, again due to the stop of fin, these hot-airs that originally can form convection current can be partially formed high-temperature region relatively independent one by one between adjacent fin, and low-pressure area can be formed because of the eddy current of wind at the lee face of module, the minimizing of air can reduce the speed of heat exchange, reduce radiating effect on the whole.
And the invention have employed closed cooling ring structure, when horizontal direction crosswind blows, the convection current in cooling ring can not be affected, only can form to hot-air effect of bleeding on cooling ring top, formed cold air in cooling ring bottom and accelerate tonifying Qi effect, radiating effect has had great lifting.And the lateral surface of almost plane also has blocking effect to crosswind, horizontal direction wind can 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 effectively optimizes heat conduction stream, improves the heat-conducting effect that heat of light source conducts to cooling ring.
In sum, the invention has the following advantages:
1, avoid the easy dust stratification of top radiating structure of conventional lamp, and then affect the problem of radiating effect;
2, the radiating effect of light fixture is effectively improved.
