Abstract
The utility model relates to a bulb lamp. The bulb lamp comprises a die-casting lamp body, wherein a hollow cavity is formed in the die-casting lamp body, a patch light-emitting diode (LED) aluminum substrate which directly contacts with the die-casting lamp body is arranged in the die-casting lamp body, the back of the patch LED aluminum substrate is connected with a heat dissipation aluminum extrusion block which is used for educing heat of the patch LED aluminum substrate, the heat dissipation aluminum extrusion block is arranged in the hollow cavity of the die-casting lamp body, and heat conduction silicone layers are arranged between the patch LED aluminum substrate and the die-casting lamp body, and between the patch LED aluminum substrate and the heat dissipation aluminum extrusion block. The bulb lamp has the advantages of being reasonable in structure, good in heat conduction performance and heat dissipation performance, and long in service life.
Description
Technical field
The utility model relates to a kind of indoor illumination light fixture, particularly a kind of bulb lamp.
Background technology
Present commercial or home LED bulb lamp contacts insufficient heat dispersion that causes poor with the shell lamp body due to the bulb lamp aluminium base, when power is larger, easily cause accumulated heat, shortens LED service life, and more can shorten light fixture service life during more high-power use.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of rational in infrastructure, heat conduction, perfect heat-dissipating, the bulb lamp of long service life.
The purpose of this utility model is achieved through the following technical solutions: a kind of bulb lamp, comprise the die casting lamp body, be provided with cavity in the die casting lamp body, be provided with direct and the contacted paster LED aluminium base of die casting lamp body in the die casting lamp body, the back side of paster LED aluminium base is connected with the radiation aluminium crushing block of deriving for paster LED aluminium base heat, the radiation aluminium crushing block is placed in the cavity of die casting lamp body, between paster LED aluminium base and die casting lamp body, be equipped with the thermal grease conduction layer between paster LED aluminium base and radiation aluminium crushing block.
The utility model compared with prior art has the following advantages: add a radiation aluminium crushing block by the back side at the paster LED aluminium base, can fully the heat in the paster LED aluminium base be exported on die casting lamp body and radiation aluminium crushing block, and distribute very soon, by the thermal grease conduction layer can fill up between paster LED aluminium base and die casting lamp body, micro gap between paster LED aluminium base and radiation aluminium crushing block, more be conducive to heat radiation, this fitting structure is reasonable, heat conduction, perfect heat-dissipating, long service life.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-paster LED aluminium base, 2-radiation aluminium crushing block, 3-die casting lamp body, 4-thermal grease conduction layer.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Show the specific embodiment of a kind of bulb lamp of the utility model as Fig. 1, comprise die casting lamp body 3, be provided with cavity in die casting lamp body 3, be provided with direct and the contacted paster LED aluminium base 1 of die casting lamp body 3 in die casting lamp body 3, the back side of paster LED aluminium base 1 is connected with the radiation aluminium crushing block 2 of deriving for paster LED aluminium base 1 heat, radiation aluminium crushing block 2 is placed in the cavity of die casting lamp body 3, between paster LED aluminium base 1 and die casting lamp body 3, be equipped with thermal grease conduction layer 4 between paster LED aluminium base 1 and radiation aluminium crushing block 2.
Bulb lamp described in the utility model, add a radiation aluminium crushing block 2 by the back side at paster LED aluminium base 1, so just can fully the heat in paster LED aluminium base 1 be exported on die casting lamp body 3 and radiation aluminium crushing block 2, and distribute very soon, by thermal grease conduction layer 4 can fill up between paster LED aluminium base 1 and die casting lamp body 3, micro gap between paster LED aluminium base 1 and radiation aluminium crushing block 2, more be conducive to heat radiation, this fitting structure is reasonable, heat conduction, perfect heat-dissipating, long service life.
