Description
Technical field
The utility model relates to a kind of heat dissipation type LE D bulb lamp, belongs to the bulb technologies field.
Background technology
Bulb is as the normal lighting instrument, and receive much concern its service life.At present, the principal element that influences bulb service life is the radiating effect of LED lamp group and power driving circuit.Chinese patent ZL201020599569.1 discloses a kind of light emitting diode bulb with radiator structure; Comprise lamp housing, be installed on the said lamp housing diffuser and by the luminescence component of said diffuser and said lamp housing capping, offer many air vents on the said lamp housing.The radiator structure that this bulb provides can make full use of the air heat radiation; Efficiently solve light emitting diode and driving power heating problem; Reduced LED brightness decay and reached the prolongation entire product purpose in service life, but also there is certain shortcoming in it: owing to offer many air vents on the lamp housing, this bulb can only carry out the direct heat conduction with the air that the external world gets in the lamp housing; But do not form the circulative convection heat exchange, radiating effect is not ideal.
The utility model content
The utility model provides a kind of heat dissipation type bulb lamp in order to overcome the deficiency that prior art exists.
The utility model can be achieved through taking following technical scheme:
A kind of cooling type LED bulb lamp comprises lamp housing, lampshade, substrate, LED lamp group, power driving circuit and lamp holder, and said lampshade is installed in the bottom of lamp housing; Lamp holder is installed in the top of lamp housing, and substrate is fixed in the lamp housing, and LED lamp group is fixed in the bottom of substrate; Lamp holder links to each other with LED lamp group electricity through power driving circuit; This bulb also comprises radiator, and said radiator is fixed on the substrate, and the upper and lower of said lamp housing is provided with air-vent.
On the basis of the above, the said power driving circuit of the utility model is integrated on the power panel, and said power panel is fixed on the top of radiator, helps the power driving circuit heat radiation.
The said lamp holder of the utility model is installed in the top of lamp housing through the lamp holder fixture; Said lamp holder is screwed socket or non-threaded lamp holder; Said substrate is fixed in the lamp housing through screw.
Compared with prior art; The beneficial effect of the utility model is: the utility model is provided with air-vent in the top and the bottom of lamp housing; Utilize radiator that the heat of LED lamp and power driving circuit is dispelled the heat through the air circulation convection action of air-vent; Make bulb be in normal operating conditions for a long time, prolonged the service life of bulb.
Description of drawings
Fig. 1 is the structure chart of the cooling type LED bulb lamp of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the most preferred embodiment of the utility model is described in detail.
As shown in Figure 1, the cooling type LED bulb lamp of the utility model comprises lamp housing 1, lampshade 2, substrate 3, LED lamp group 4, power driving circuit 5, lamp holder 6 and radiator 7; Said lampshade 2 is installed in the bottom of lamp housing 1; Lamp holder 6 is installed in the top of lamp housing 1 through lamp holder fixture 8, and substrate 3 is fixed in the lamp housing 1 through screw, and LED lamp group 4 is fixed in the bottom of substrate 3; Lamp holder 6 links to each other with power driving circuit 5; Power driving circuit 5 links to each other with LED lamp group 4 through electric wire, and said radiator 7 places in the lamp housing and is fixed on the substrate 3, and the upper and lower of said lamp housing 1 is provided with air-vent 9.In order to make heat conduction and radiating effect better, between said substrate, radiator, substrate and the radiator fixedly the screw of usefulness all adopt aluminum to process.The said power driving circuit 5 of the utility model can be integrated on the power panel 10, and said power panel 10 is fixed on the top of radiator 7, helps power driving circuit 5 heat radiations.The lamp holder 6 of the utility model can adopt screwed socket or non-threaded lamp holder, and power driving circuit 5 adopts drive circuit commonly used.Better for the circulative convection radiating effect that makes radiator and air, radiator is equipped with many vent ribs by its body surfaces.
The course of work of the cooling type LED bulb lamp of the utility model is following; After bulb energising work; The heat that LED lamp group 4 produces passes on the radiator 7 through connected substrate 3; Heat on substrate 3 and the radiator 7 is transmitted in the air in the lamp housing 1 and produces hot-air, and this hot-air rising is discharged by the air-vent 9 on the top of lampshade, at this moment; Discharge owing to hot-air in the lamp housing 1 produces negative pressure; The outer cold air of lamp housing 1 enters into from the air-vent 9 of the bottom of lamp housing 1 in the lamp housing 1 and carries out heat exchange with substrate 3 and radiator 7 again, and so just formation air circulation convection current in the air-vent of the upper and lower of lamp housing 1 is constantly cooled off substrate 3 and radiator 7; Thereby make LED lamp group 4 be in normal operating conditions always, reach the purpose that prolongs bulb life.
The above person of thought; Be merely the preferred embodiment of the utility model; When the scope that can not limit the utility model enforcement with this; The content of promptly being put down in writing according to the utility model claim and utility model specification has generally been done simple equivalent and has been changed and modification, all still belongs within the utility model claim institute covering scope.In addition, summary part and title only are the usefulness that is used for assisting the patent document search, are not the interest field that is used for limiting the utility model.
