The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 5, an embodiment of radiator for LED lamp of the present utility model is proposed, this LED lamp comprises thermal column 10 and the heat radiation limb 20 of some axial windings in the outside wall surface of thermal column 10 with radiator, thermal column 10 is main body radiator portion, the front end face of heat radiation limb 20 is made as for the light source installed surface 22 of LED light source is installed, be plane layout, the heat that heat radiation limb 20 can produce the LED light source being installed on light source installed surface 22 is derived fast, and in heat radiation, heat is conducted to thermal column 10, dispel the heat together with thermal column 10.
The thermal column 10 of this product and heat radiation limb 20 are splits, and by aluminium alloy compression casting moulding, thermal conductivity factor is high.Thermal column 10 and heat radiation limb 20 are separately produced, and can reduce production difficulty, are easy to machine-shaping.
In the outside wall surface of thermal column 10, be axially arranged with some cross sections and be major arc setting and opening mounting groove 11 outwardly, at the back side of heat radiation limb 20, be provided with the cross section of mounting groove 11 adaptations and be the connecting rod 21 that major arc arranges, mistake connecting rod 21 plug-in mountings are entered in mounting groove 11, the limb 20 that can make to dispel the heat is fastened on thermal column 10, assembly operation between thermal column 10 and heat radiation limb 20 is simple, can complete fast.
Because mounting groove 11 is opening major arc setting outwardly, and connecting rod 21 is also equipped with as circular-arc with mounting groove 11, thereby connecting rod 21 inserts after mounting groove 11, and connecting rod 21 can rotate in mounting groove 11, thereby heat radiation limb 20 can swing.User's limb 20 of rotatably dispelling the heat, the limb 20 that makes to dispel the heat is rocked to outward appearance and the light efficiency that different positions changes radiator integral, and flexibility is strong, can meet user's multiple demand.The pendulum angle of heat radiation limb 20 is the opening angle of mounting groove 11, by the opening angle of mounting groove 11, is determined.
The cross section of this heat radiation limb 20 is T-shaped setting, its front end face is used for installing LED light source, connecting rod 21 is arranged on the back end of heat radiation limb 20, back heat radiation limb 20 is also distributed with some radiating fins 24, radiating fin 24 is vertically set on the back wall of heat radiation limb 20, between radiating fin 24, interval arranges, can increasing heat radiation area.
This thermal column 10 is hollow setting, in the internal face of thermal column 10 and outside wall surface, is equipped with some radiating fins 12, can increasing heat radiation area, improve radiating efficiency.Some is bifurcated setting for this radiating fin 12, and some is monolithic setting.
On the relative two sides of heat radiation limb 20, be provided with the draw-in groove 23 for clamping lampshade, for clamping lampshade, facilitate the assembling of lampshade.Because heat radiation limb 20 is to produce separately, independent machine-shaping, the draw-in groove 23 of its side and the easier machine-shaping of radiating fin 24 at its back side.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
