The utility model provides an LED radiating device, which comprises a radiator, a lampshade and a lamp holder, wherein the radiator comprises a base board and a plurality of radiating sheets; the base board is provided with an upper surface and a lower surface; the upper surface is provided with at least one illuminating source; one end of the radiating sheets is equidistantly and annularly arranged at the outer edge of the lower surface; the radiating sheets determine an inner cavity and a plurality of radiating holes; the lamp holder is connected to the other end of the radiating sheets; and at least one radiating fan is arranged in the inner cavity of the radiator. When the LED of the utility model works and generates heat, the heat is radiated through the radiator. The radiating property of the radiator is promoted and the air contacting quantity of the radiator is increased by running the radiating fan arranged on the base board. The heat generated by the LED is radiated into air through the radiating hole so as to greatly lower the working temperature of the LED and realize the stable effect of the LED under the working state.

Description

A kind of heat abstractor of LED lamp
Technical field
The utility model relates to a kind of heat abstractor, more specifically is meant a kind of heat abstractor of LED lamp.
Background technology
The light fixture that is used at present throw light on can be divided into ordinary light source and energy-conserving light source according to light emitting source, in the energy-conserving light source again with the energy-conserving and environment-protective the most of semiconductor LED light source, led light source has brightness height, long service life, do not contain virose characteristics such as mercury, is the first-selected lighting sources of environmental protection that various countries, the present whole world generally acknowledge.
But because LED needs strict control temperature as lighting, because LED is a kind of semi-conducting material, the same with general-purpose diode have a PN junction, because the power of highlighted diode is relatively big, so it is identical with power semiconductor, need to consider heat dissipation problem, the too high meeting of junction temperature directly influences the life-span of LED, and can increase the light decay of LED, the meeting that situation is serious burns out LED, become one of problem of insider's care so how effectively to improve the radiating effect of LED light fixture, and traditional LED light fixture only is embedded LED in the heat sink that the aluminium material manufacturing forms, utilize the aluminium material good performance of heat dissipation, the heat that LED is produced distributes, and then reduces the temperature that raises when LED works.
But, this radiating mode is in concrete the use, the heat that produces when still failing more efficiently minimizing LED work, because the heat that produces during LED work, because the restriction of cooling plate structure, itself and air contact-making surface are limited, iff being the words that simply rely on heat sink to dispel the heat as media, be not the most effective, so can not more effectively prolong the service life of LED.
Summary of the invention
Main purpose of the present utility model is to overcome the not good problem of radiating effect that present LED light fixture exists, for people provide a kind of perfect heat-dissipating, improved security, the reliability of led light source, made with LED the heat abstractor of the LED lamp that is the operation that the illuminator of light source can be more efficient, safer, more stable.
Another purpose of the present utility model in providing a kind of simple in structure, is made the heat abstractor of simple LED lamp again.
The technical solution adopted in the utility model is: comprise radiator, lampshade and lamp holder, wherein, this radiator comprises base plate and polylith fin, this base plate has upper surface and lower surface, this upper surface is provided with at least one light emitting source, the equidistant ring of one end of this polylith fin is located at the outer rim place of this lower surface, and determine an inner chamber and a plurality of thermovent by this polylith fin, this lamp holder is connected on the other end of this polylith fin, is provided with at least one radiator fan in the inner chamber of this radiator.
Particularly, described light emitting source is LED.Certainly, brighter for the brightness that makes lamp, a plurality of light emitting sources can be set as required.
Particularly, be provided with control circuit board in this inner chamber, this control circuit board is electrically connected with this lamp holder, this light emitting source, this radiator fan respectively by power line.
Particularly, the lower surface of this base plate is provided with the screwed hole that is used for fixing radiator fan, and this radiator fan is fixedly connected on this lower surface by fixed screw.
In one embodiment, described radiator fan can be set to one; In a further embodiment, described heat radiation wind looses and can be 2 or a plurality of.
The beneficial effects of the utility model are: the utility model structurally comprises radiator, lampshade and lamp holder, wherein, this radiator comprises base plate and polylith fin, this base plate has upper surface and lower surface, this upper surface is provided with at least one light emitting source, the equidistant ring of one end of this polylith fin is located at the outer rim place of this lower surface, and determine an inner chamber and a plurality of thermovent by this polylith fin, this lamp holder is connected on the other end of this polylith fin, is provided with at least one radiator fan in the inner chamber of this radiator.When LED work of the present utility model and generation heat, heat passes through radiator heat-dissipation, and by moving the heat dispersion that the radiator fan of installing on this base plate improves radiator, strengthen the air contact amount of this radiator, the heat that LED is produced is dispersed in the air by these a plurality of thermovents, thereby the operating temperature of LED is reduced greatly, realize guaranteeing to descend in working order the stable effect of LED.In addition, by its special structure design, the utility model can also the simple and simple effect of making of implementation structure.
