Description
Technical field
The utility model relates to the LED lighting field, particularly a kind of LED bulb lamp.
Background technology
LED (LightingEmittingDiode) illumination promptly is a led lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, in semiconductor, through carrier compound energy of emitting surplus takes place and causes photo emissions, directly sends red, yellow, blue, green, blue or green, orange, purple, white light; The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.The LED illuminating product has that volume is little, power consumption is low, long service life, advantage such as environmental and durable, be called as the 4th generation lighting source or green light source.At present, as the LED light fixture of lighting source have much make blistered, purpose be for original lamp socket coupling, just directly change old-fashioned bulb into the LED bulb lamp and get final product.But this LED bulb lamp owing to adopt whole airtight bulb shell to make that its radiating effect is relatively poor, has influenced the service life of LED bulb lamp.
The utility model content
The problem that the utility model solves provides a kind of LED bulb lamp, solves the problem that existing LED bulb lamp radiating effect is relatively poor, service life is short.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of LED bulb lamp comprises: lamp holder, and said lamp holder is provided with the screw thread that is used to be connected in power socket; Radiating seat, the hollow out stage body that said radiating seat is surrounded by strip shape body, one of which end are fixed on the said lamp holder, and the other end connects lampshade; Substrate, said substrate is a circular metal plate, is positioned at an end of said radiating seat, and said substrate is provided with drive circuit on the one side of lamp holder, and another side is provided with led module; Lampshade, said lampshade is a hemispherical, is connected on the end of said radiating seat; Said drive circuit connects said led module and external power source.
Further, the parabolic hollow out stage body that surrounds for the metal strip body of said radiating seat.
Further, said radiating seat is the parabolic hollow out stage body that nonmetal strip shape body surrounds.
Further, be provided with reinforcement in the middle of the said hollow out stage body.
Further, said lamp holder one end is provided with a pylon, and said substrate is fixed on the said pylon.
Compared with prior art, the advantage of the utility model technical scheme is:
Through radiating seat being arranged to the hollow out stage body; Strengthen inner with the extraneous cross-ventilation of LED bulb lamp; The heat that makes drive circuit come out can be taken away by cross-ventilation very soon, thereby effectively solves the heat dissipation problem of LED bulb lamp, improves the service life of LED bulb lamp.
Description of drawings
Fig. 1 is the utility model specific embodiment decomposing schematic representation.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
Fig. 1 is the utility model specific embodiment decomposing schematic representation.As shown in Figure 1, a kind of LED bulb lamp comprises lamp holder 1, radiating seat 2, substrate 3 and lampshade 4, and said radiating seat 2 is connected between lamp holder 1 and the lampshade 4, and 3 of said substrates are arranged on the end that said radiating seat 2 is connected with said lampshade 4.
Said lamp holder 1 one ends are provided with screw thread 11, are used to connect power socket, and the other end then is a protruding pylon 12, and the through hole 13 that is used for through power line is arranged in the middle of the said pylon 12.
The hollow out stage body that said radiating seat 2 is surrounded by strip shape body 21, said strip shape body 21 can be a metal, also can be nonmetal, like heat resistant plastice, is preferably metal; Said hollow out stage body is a parabolic, and the bigger end of an end is less, can for hemispherical also can be for semiellipse spherical or other shapes; Can be provided with reinforcement 22 in the middle of the said hollow out stage body, be used to strengthen the intensity of hollow out stage body.
Said substrate 3 is a circular metal plate, is provided with a hole 31 between wherein, and said substrate 3 is fixed on through screw on the pylon 12 of said lamp holder 1, and said hole 31 communicates with through hole 13 on the pylon 12; Said substrate 3 one sides are provided with the drive circuit (not shown), and another side then is provided with the led module (not shown), is connected by the lead through hole 31 between the two; Drive circuit couples together led module and external power source, is used for the power supply of led module.
Said lampshade 4 is a hemispherical, generally adopts transparent plastics to process, and led module is played a protective role.
The utility model specific embodiment is through being arranged to radiating seat the hollow out stage body; The heat that well drive circuit and LED lamp group is sent is by convection in the air; And because the hollow out stage body is up-small and down-big shape; Heat is dispersed in the air, thereby solves the heat dissipation problem of LED bulb lamp effectively, improve the service life of LED bulb lamp.
Though the utility model with preferred embodiment openly as above; But it is not to be used for limiting the utility model; Any those skilled in the art are in spirit that does not break away from the utility model and scope; Can make possible change and modification, so the protection domain of the utility model should be as the criterion with the scope that the utility model claim is defined.
