Description
Technical field
The utility model relates to the LED lighting field, is specifically related to a kind of LED lamp with conduction type radiator structure.
Background technology
The LED lamp is one of the novel green light source of conventional incandescent bulb as an alternative, has good market prospects.About the LED lamp with material and processing technology, the process used of light fixture industry has following several at present: (1) general plastics: use plastic injection-moulded technique, but the radiating effect extreme difference of material of general plastics own; (2) heat-conducting plastic: use plastic injection-moulded technique, the radiating effect of heat-conducting plastic is slightly better than general plastic material, and still, on market, variation is not yet carried out in the product development of heat-conducting plastic, and therefore, this material still belongs to expensive material; (3) aluminium alloy: use extrusion process, the aluminium alloy material must be crossed after multiple procedure and could be accepted by market.Because processing technology is loaded down with trivial details, indirectly increase cost, so production unit cost is higher; The aluminum alloy material that is fit to die casting only has a few aluminium material available on market; Although the radiating effect of aluminium alloy is better than heat-conducting plastic, need do in appearance because of it spray paint coating or electroplating processes, its radiating effect is had a greatly reduced quality; (4) aluminium section bar: use aluminium extruded type or aluminium to take out technique, the material of aluminium section bar must be after secondary procedure, and use milling process just can be processed into the required modeling effect in market, so the production unit cost of aluminium section bar is high, manufacturing cost is increased.The aluminium section bar radiating effect is better than aluminium alloy compression casting material.
According to the above description as can be known, the material that cheap, processing procedure is conveniently taken again soon, as plastics, heat-conducting plastic, be only suitable for using for the light fixture of low wattage power.Therefore, consider heat radiation and performance, all use the good metal material of thermal conductivity (as aluminium alloy and aluminium section bar) to make heat abstractor at present, but because the heat loss through radiation area of heat abstractor is limited, cause radiating effect still not good, thereby affected the life-span of LED lamp.
The utility model content
The utility model provides a kind of LED lamp with conduction type radiator structure, by existing LED lamp is improved, to solve the deficiency of prior art.
in order to solve the problems of the technologies described above, a kind of LED lamp with conduction type radiator structure of the present utility model, comprise heat-dissipating casing and be installed on lamp holder and the diffuser at heat-dissipating casing two ends, described heat-dissipating casing is hollow-core construction, its all side evenly is provided with some heat radiation convex epireliefs, form heat dissipation channel between some heat radiation convex epireliefs, the top of described heat-dissipating casing is the design of closing up, closing in place is provided with the clamping ring that is connected with lamp holder, described clamping ring is provided with some through holes, some through holes on this clamping ring and described heat dissipation channel form cross-ventilation, thereby be beneficial to the heat conduction, strengthen heat sinking function.
Further, described some heat radiation convex epireliefs can be some strands of (22 strands or 40 strands) upper coarse and lower fine convex epireliefs, can be also some strands of wide convex epireliefs, can be also the convex epireliefs that some thighs are zigzag shape, in the middle of can also being, the thick convex epirelief in thin two, can select according to actual conditions.Above-mentioned convex epirelief can adopt extrusion molding manufacturing or die cast manufacturing.
Further, the through hole that flows to out for air feed on described clamping ring can be circle, rectangle or other shapes, and different shapes can make this LED light fixture that different aesthetic feelings is arranged.
