Abstract
The utility model relates to an LED lamp radiator comprising a radiator body, wherein a convective ventilation chamber is arranged in the radiator body, and ventilation holes are arranged on the wall of the chamber; heatconducting reinforcing ribs are arranged in the convective ventilation chamber and provided with the ventilation holes; external radiating fins are arranged on the external surface of the top part; and internal radiating fins are arranged on the bottom of the convective ventilation chamber. The LED lamp radiator has the advantages of good radiation performance, light weight and safe use and is applicable to various LED lamps, especially high-power LED lamps.
Description
Technical field
The utility model relates to a kind of LED lamp radiator, especially relates to a kind of high-power LED lamp radiator that is applicable to that road lighting is used.
Background technology
Along with the fast development of economy and the exhaustion day by day of world energy sources, energy-conservation and environmental protection is paid attention to by people gradually.The breakthrough of high-power LED lamp technology makes the light source that adopts high light efficiency replace conventional light source to become a reality.The LED light fixture is as the new generation of semiconductor lighting source, advantage such as have efficient low-consume, energy-conserving and environment-protective, response is fast, the life-span is long.But the LED light fixture can produce a lot of heats when work, if these heats can not in time distribute, can influence the light decay and the service life of LED light fixture.Therefore, solve heat dissipation problem and become one of technology of most critical in the high-power LED lamp lighting engineering.At present, some adopts the die casting aluminium lampshade LED light fixture, such lampshade inner space sealing, and also narrow and small, can not form effective cross-ventilation, can only outwards dispel the heat by lampshade shell, radiating efficiency is low; Also have some LED light fixtures to adopt the shell that has fin, heat dispersion increases, but inside also lacks cross-ventilation, thereby radiating efficiency is still not good enough; For rising to radiating efficiency, adopt the mode that enlarges cooling surface area usually, promptly adopt large-scale lampshade, but this can increase raw materials consumption, increase lampshade shell weight, the safety that is unfavorable for light fixture is usefulness.
The utility model content
The purpose of this utility model is to provide a kind of perfect heat-dissipating, and is in light weight, LED lamp radiator safe in utilization.
The technical solution of the utility model is: it comprises radiator body, and radiator body inside is provided with the ventilation by forced draft chamber, and the chamber wall is provided with air vent.
Below be further improved preferred version:
Heat conduction reinforcement is set in the ventilation by forced draft chamber; Heat conduction reinforcement is provided with air vent;
Outer surface of cupular part is provided with outer radiating fin; The height of described outer radiating fin is preferably 4-15mm (preferred 6-12mm is 7-10mm more preferably).Suitable outer radiating fin height had both helped guaranteeing radiating efficiency preferably, made lamp surface have self-cleaning ability preferably again.
Bottom, ventilation by forced draft chamber is provided with interior radiating fin;
Above preferred feature helps further to improve the radiator heat-dissipation performance, helps guaranteeing that the heat with the LED lamp produces in time leaves.
Radiator body can be made of left radiator body and right radiator body, and this helps breaking through road lamp cooling section bar maximum cross-section width can not increase whole radiating effect and attractive in appearance greater than the restriction of 350mm.
The utility model perfect heat-dissipating, in light weight, safe in utilization.
The utility model is applicable to various LED light fixtures, and is specially adapted to high-power LED lamp.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1
With reference to accompanying drawing: present embodiment is made of left radiator body 1 and right radiator body 7, and left radiator body 1 is connected with bolt 5 by chute with right radiator body 7; Left side radiator body 1 and right radiator body 7 inside are provided with the ventilation by forced draft chamber, and the chamber wall is provided with air vent 6;
When temperature contrast being arranged everywhere in the vented cavity, the vented cavity internal air pressure is different, makes to produce free convection in the chamber, thereby heat is taken out of fast; Air can also enter in the chamber by air vent and circulate, and further improves heat dispersion.
Be provided with heat conduction reinforcement 4 in the vented cavity, also be provided with air vent on the heat conduction reinforcement 4; Outer surface of cupular part is provided with outer radiating fin 2, radiating fin 3 in bottom, ventilation by forced draft chamber is provided with, and they all help further to improve the radiator heat-dissipation performance, guarantee the heat that the LED lamp produces is in time left.
The height of outer radiating fin 2 is 7.2mm, and this height can guarantee radiating efficiency preferably, makes lamp surface have self-cleaning ability preferably again.
A left side radiator 1 and right radiator 7 interlock by chute, and screw is fixed, and two radiators are connected as one, and having broken through road lamp cooling section bar maximum cross-section width can not increase whole radiating effect and attractive in appearance greater than the restriction of 350mm.
Embodiment 2
The height of the outer radiating fin 2 of present embodiment is 12mm.Surplus with embodiment 1.
Embodiment 3
The height of the outer radiating fin 2 of present embodiment is 6mm.Surplus with embodiment 1.
