Preferably, lamp tube afterbody also comprises the back tube, and the power supply fixed mount is installed in the tube of back.

Preferably, said lamp tube is an aluminium lamp tube.

Preferably, lamp tube afterbody has one and is used to the bonnet that prevents to get an electric shock, and bonnet covers lamp tube afterbody.

Preferably, said back tube is a tube behind the aluminium, and said bonnet is the aluminium bonnet.

Preferably, the LED module comprises LED and LED control chip.

Technique scheme can be found out, installs because the utility model embodiment adopts LED module and power module to separate, and the LED module is fixed on the head of lamp tube; And power module is fixed on lamp tube afterbody; Therefore, avoided the stack of LED module and power module heat, and the back tube that installs additional and bonnet adopt tube and aluminium bonnet behind the aluminium; Increase the integral heat sink area of light fixture, had significant more radiating effect.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the blast structure chart of the high heat radiation of LED light fixture among the utility model embodiment.

The specific embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment:

The utility model embodiment provides the high heat radiation of a kind of LED light fixture, and is as shown in Figure 1, comprising: the lamp tube 1 of hollow and bottom lock; LED module 3, conducting strip 2 is used for fixing the light source fixing frame 4 of LED module; The power module 6 that is used for the driving LED module, power supply fixed mount 5.The LED module comprises LED and led chip.

The structure of lamp tube 1 is similar to bowl; Lamp tube 1 hollow can ccontaining LED module, conducting strip and light source fixing frame, and conducting strip 2 need conduct to the heat of LED module 3 on the lamp tube 1; Therefore the afterbody of lamp tube 1 need have the tube end of sealing; Being the boundary at the bottom of this, the head that is lamp tube 1 of tube front side, the end, the afterbody that is lamp tube 1 of tube end rear side.

Wherein, The one side of conducting strip 2 is attached on the LED module 3, and the another side of conducting strip 2 is attached on the diapire of lamp tube 1, and the diapire of the lamp tube 1 here promptly refers to the tube end of the sealing that above-mentioned lamp tube 1 is had; Center at the bottom of conducting strip 3 just can be attached to tin; Light source fixing frame 4 is fixed on lamp tube 1 head with LED module 3, and power module 6 is fixed on the power supply fixed mount 5, and power supply fixed mount 5 is installed in the afterbody of lamp tube 1.

Lamp tube 1 afterbody also comprises back tube 7, and back tube 7 can be integrated with being connected of lamp tube, also can be partial installation; If back tube 7 adopts the structure of partial installations, back tube 7 can screw thread be screwed in the afterbody of lamp tube 1, also can the back tins 7 be connected on the lamp tube 1; Syndeton for back tube 7 and lamp tube 1 should not constitute the restriction to the utility model protection domain; Power supply fixed mount 5 is installed in the back tube 7 among the utility model embodiment, and back tube 7 is fastened on the lamp tube 1 through screw, and more direct with the heat conduction of lamp tube 1 in order to guarantee back tube 7; Back tube 7 can directly be fixed on the diapire of lamp tube 1; Because power module 6 all is integrated on the pcb board, so 5 of power supply fixed mounts adopt two set bolts to get final product, and this set bolt should have the good heat conductive performance.

Lamp tube 1 afterbody has one and is used to the bonnet 8 that prevents to get an electric shock; Bonnet 8 covers lamp tube 1 afterbody, it is understandable that, lamp tube 1 afterbody is connected with back tube 7 among the utility model embodiment; Therefore tube 7 got final product after bonnet 7 covered; Tube behind the back tube 7 employing aluminiums among the utility model embodiment, bonnet 8 adopts the aluminium bonnets, and aluminium has better heat conduction and heat radiation performance.

With respect to existing LED light fixture, the high heat radiation of the LED that the utility model embodiment provides light fixture, its light source (LED module) is close on the lamp tube through conducting strip; The heat that helps light source directly conducts on the lamp tube; The lamp tube is for the moulding of heat radiation aluminium, and is big with the air contact area, helps carrying out sufficient heat exchange with air; Need not to increase in addition radiator, under the condition that guarantees the radiator structure that the LED light fixture is good, reduced manufacturing cost greatly.And the utility model embodiment adopts LED module and power module to separate installation; The LED module is fixed on the head of lamp tube, and power module is fixed on lamp tube afterbody, therefore; Avoided the stack of LED module and power module heat; And the back tube that installs additional and bonnet adopt tube and aluminium bonnet behind the aluminium, increased the integral heat sink area of light fixture, has significant more radiating effect

More than the high heat radiation of LED light fixture that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the core concept of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
