Description

A kind of LED fitting structure that utilizes the fan enhance heat
Technical field
The utility model relates to a kind of LED fitting structure that utilizes the fan enhance heat, belongs to technical field of semiconductor illumination.
Background technology
Along with the lifting of LED performance and the decline of cost, obtained fast development with LED as the illuminating product of light source, and replaced the traditional lighting product gradually and be applied to some room lighting places.The general volume of traditional indoor illumination light fitting is less, replaces traditional lighting source with LED as light source, for example during light source such as incandescent lamp, Halogen lamp LED, fluorescent lamp, often is faced with the problem of efficiently radiates heat area wretched insufficiency.Especially in the light fixture product of ask for something high-color rendering illumination, the light efficiency of LED temporarily also can't surpass 100lm/W, must improve the luminous flux of the whole lamp of LED light fixture by the way that increases power, this must cause the LED light fixture to be faced with severe more heat radiation challenge.
In room lighting, because environment for use is relatively loose, therefore, utilize fan to carry out the forced convertion heat radiation, become the inevitable choice of high-power LED indoor lamp when structural design.But, in the present LED indoor lamp, as shown in Figure 1, led light source generally is fixed on one side of heat sink, and fin is at the another side of heat sink, and fan is positioned on the fin then, reduce the fin temperature by forced convertion, and then reduce the junction temperature of led light source.This mode of utilizing fan to carry out forced heat radiation is effectively, but an existing major issue is to have influence on the outward appearance and the volume of whole light fixture.Indoor lamp is compared outdoor lamp, and interior decoration light fixture especially has higher requirement for the moulding and the outward appearance of light fixture, needs light fixture can not only satisfy lighting criteria, can also play the effect that beautifies indoor environment.In brief, be with illumination, heat radiation and attractive in appearance the combining of LED light fixture, so, this fan radiating mode in the accompanying drawing 1 just can not satisfy the requirement attractive in appearance of indoor lamp.
The utility model content
The purpose of this utility model is exactly at above shortcomings in the prior art, and the Lights section and the radiator portion of LED light fixture are improved integration, and a kind of LED fitting structure that utilizes the fan enhance heat is provided.Utilize fan that the forced convertion heat radiation is carried out in the space in the middle of the distributed cavity, thereby make the radiating mode of fan have disguised preferably.Like this, the LED light fixture just has bigger creativeness when structure and appearance design, thereby can satisfy illumination, heat radiation and demand attractive in appearance simultaneously.
The purpose of this utility model is to realize like this, a kind of LED fitting structure that utilizes the fan enhance heat, comprise radiator and fan, it is characterized in that, extend two or more separate radiators on the described radiator, constitute between the radiator and the outside air channel that is connected, fan is arranged in the internal cavities of radiator, the internal cavities of radiator is provided with several of exterior and crosses the wind passage, wherein has at least one to cross the wind passage and communicate with air channel between the radiator.
Described wind passage excessively is air vent or ventilation slot.
Fan sucks the cross wind passage of air from the radiator cavity, blow out, and through the passage between the radiator, the heat that radiator gives out is taken away.Because led light source or light source assembly are directly fixed on the described independent radiator, can directly heat be taken away from independent radiator by fan, thereby can effectively reduce the junction temperature of LED.
The utility model novel and reasonable structure is manufactured easily good heat dissipation effect.Fan is positioned in the internal cavities of radiator, can not expose fan on the one hand, can protect fan to avoid the factor affecting such as impact of external environment on the other hand.Adopt independent radiator can avoid fin only to have the function of heat radiation, can also make fin have the effect of light-source chamber matrix concurrently.Distributed independent radiator can make the LED light fixture can realize the illumination of various angles, and the heat dissipation channel between the radiator can effectively be utilized by fan again, carries out forced heat radiation.Therefore, the utility model has overcome the heat radiation difficult problem of general high-capacity LED light fixture, has realized illumination, heat radiation and the demand attractive in appearance of LED light fixture simultaneously.

Among the figure: 1LED light source or light source module, 2 radiators, 3 fans, 4 board-like independent radiators, 5 lampshades, 6 driving governors, 7 are crossed wind passage, 8 and are crossed wind passage, 9 air channels, 10 pillar independence radiators.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the utility model.
Embodiment 1
As shown in Figure 2, be a kind of structure of the present utility model.Extend two or more separate board-like independent radiators 4 on the radiator 2, constitute between the board-like independent radiator and the outside air channel 9 that is connected, fan 3 and driving governor 6 are arranged in the internal cavities of radiator, the internal cavities of radiator is provided with several of exterior and crosses wind passage 7,8, wherein has at least one to cross wind passage 7 and communicate with air channel between the radiator.Have certain clearance in the heat radiation cavity of fan 3, driving governor 6 and radiator 3, this gap is as crossing wind passage 8 (air intake of air, air-out passages).Be furnished with several independently board-like independent radiators 4 on the top of radiator 2, be fixed with led light source or light source module 1 on the board-like independent radiator 4, lampshade 5 covers on led light source or light source module 1, and is fixed on the radiator 2.There is certain interval between the adjacent board-like independent radiator 4, as the air-out of air or the air channel 9 of air intake.On the matrix of radiator 2, the bottom of promptly board-like independent radiator 4 is distributed with some wind passage (air vent or ventilation slots) 7 of crossing and communicates with air channel 9.Under the effect of fan 3, air will enter or discharge from crossing wind passage 7,8, and air is 9 processes through the air channel.Therefore, pass through in the present embodiment the fixing base of board-like independent radiator 4 as led light source or light source module 1, thereby make board-like independent radiator 4 have the effect of the structural matrix in lamp light source chamber concurrently, and the fan of introducing in the light fixture 3, guaranteed the great heat radiation effect of this kind fitting structure.
