Abstract
The utility model relates to a radiator for a light-emitting diode (LED) bulb lamp. The radiator adopts an integrated structure and is provided with a hollow cylinder, wherein the top end of the hollow cylinder is open and extends outwards along the edge of the opening and towards the bottom end direction of the cylinder to form a radiating outer cavity; an LED radiating surface is formed at the bottom end of the hollow cylinder; and heat generated by the LED bulb lamp is transferred out sequentially from the radiating surface, the circumferential wall of the cylinder and the radiating outer cavity. The radiator adopts a high-heat-conductivity aluminum material as a raw material, the radiating outer cavity forms a plurality of radiating fins, and the fin type structure effectively increases the radiating area. Passive and natural convection wind is generated by the temperature difference effect of the upper and the lower parts caused by heat during operation of the LED bulb lamp, so that the radiating efficiency is improved and the service life of the LED bulb lamp is prolonged.
Description
Technical field
The utility model belongs to the LED field of illumination lamp technology, is specifically related to a kind of LED bulb lamp heat radiator.
Background technology
Development along with human society; global resources are growing tension also; conventional incandescent is because energy consumption is high, the life-span is short; gradually, forbidden producing by national governments; although and the substitute products electronic energy-saving lamp has improved energy-saving effect; but owing to used the heavy metal element of many contaminated environment, run counter to again the main trend of current environmental protection.Emerging LED light fixture has the advantages such as energy consumption is low, light efficiency good, the life-span is long, pollution-free, all is far superior to the traditional lighting product on each aspect, therefore becomes gradually the only choosing of novel green lighting engineering.
Yet at present the bottleneck of LED lighting industry development is that processed complex, production cost are higher, compares with the traditional lighting product, higher price the popularization of LED lighting.The design of radiator structure also is a difficult point simultaneously, and temperature rise is too high will to cause light decay, and the LED light fixture is damaged too early.LED lamp cooling structure on the market adopts mount pad to add to dispel the heat the form of inserted sheet more, but complex structure, volume are larger, and necessity of further optimization is arranged.
The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of LED bulb lamp heat radiator simple in structure, and its technical scheme that adopts is:
A kind of LED bulb lamp heat radiator, this radiator structure that is formed in one, it has a hollow circular cylinder, this hollow circular cylinder top end opening also outwards reaches cylinder bottom direction along edge of opening and extends to form the heat radiation exocoel, this heat radiation exocoel bottom bore is greater than heat radiation exocoel top bore, described hollow circular cylinder bottom forms the LED radiating surface, and the heat that the LED bulb lamp produces outwards transmits through radiating surface, cylinder perisporium and heat radiation exocoel successively.
Further, described heat radiation exocoel forms some radiating fins along perisporium, is provided with air vent between the adjacent radiating fin, matches with the ball bubble in this heat radiation exocoel bottom.
Further, described hollow circular cylinder and heat radiation exocoel top form and the lamp holder combined structure.
Further, the radiating surface of described hollow circular cylinder bottom has a centre bore.
The effect of this radiator is as follows: when LED bulb lamp work adstante febre, heat is transmitted to rapidly on the radiating surface by aluminium base, because this radiator is to be made by the good aluminium of thermal conductivity, heat is very fast outwards to be transmitted through cylinder perisporium and heat radiation exocoel, the structural design of fin type has increased area of dissipation effectively, accelerated radiating rate, air is heated near the radiating surface of cylinder bottom simultaneously, radiator top and bottom produce temperature difference, the radiator upper temp is lower, the radiator temperature of lower is higher, gently move upward according to hot-air, the principle that cold air heavily moves downward forms free convection wind, and the air vent on the heat radiation exocoel perisporium is conducive in vertical direction rapid flow of air-flow, thereby improved radiating effect, prolonged the service life of LED bulb lamp.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
See also accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, LED bulb lamp heat radiator shown in the accompanying drawing 4, this radiator 1 structure that is formed in one, it has a hollow circular cylinder 11, this hollow circular cylinder top end opening and along edge of opening outwards reach cylinder bottom direction extend to form the heat radiation exocoel 12, this heat radiation exocoel bottom bore is greater than heat radiation exocoel top bore, aluminium base 2 Matching installations encircle in heat radiation exocoel bottom, described hollow circular cylinder 11 bottoms form LED radiating surface 14, the heat that the LED bulb lamp produces is successively through radiating surface, cylinder perisporium and heat radiation exocoel outwards transmit, described heat radiation exocoel 12 forms some radiating fins 15 along perisporium, be provided with air vent 13 between the adjacent radiating fin, match with ball bubble 4 in this heat radiation exocoel bottom, described hollow circular cylinder and heat radiation exocoel top form and lamp holder 3 combined structures, and the radiating surface of described hollow circular cylinder bottom has a centre bore.
Adopt above structure, when LED bulb lamp work adstante febre, heat is transmitted to rapidly on the radiating surface 14 by aluminium base 2, outwards transmit by hollow circular cylinder 11 perisporiums and heat radiation exocoel 12 again, because the good aluminium of radiator 1 usefulness thermal conductivity is made, the structural design that adds heat radiation exocoel fin type has increased area of dissipation effectively, so radiating efficiency significantly improves.Air is heated near the radiating surface of cylinder bottom simultaneously, radiator top and bottom produce temperature difference, the radiator upper temp is lower, the radiator temperature of lower is higher, according to the principle that hot-air gently moves upward, cold air heavily moves downward, form free convection wind, the air vent 13 on the heat radiation exocoel perisporium is conducive in vertical direction rapid flow of air-flow, thereby improved radiating effect, prolonged the service life of LED bulb lamp.
The above record, only for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do all belong to the claim that this creation is advocated, and are not limited to those disclosed embodiments.
