Description
Technical field
The utility model relates to a kind of LED (light emitting diode) light fixture, relates to a kind of high-power LED lamp specifically.
Background technology
In recent years, LED (light emitting diode) is because it has advantages such as energy-conserving and environment-protective, long service life, and development rapidly in room lighting, adnornment industry.General LED lamp comprise an end opening shell, in the enclosure circuit board, coupled LED are set, are set in the astigmatism cup on the LED and cover cover plate on the shell aperture.For asking better illuminating effect, high-power, high-brightness LED with higher output power are born thereupon, but because its power is higher, during actual the use, the heat that produces is also more, if untimely being distributed, service time one is long, causes lamp socket, shell etc. to be distributed in parts damages around the LED wick easily, on the other hand, in a single day LED itself is in and is higher than 75 ℃ working environment, its service life is just very short, and this point is particularly outstanding when LED is densely arranged.Therefore, for this employing high-power LED lamp, the heat of its generation is distributed preferably be one and treat in the problem that solves.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, heat radiation directly and the desirable high-powered LED lamp of radiating effect at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this high-powered LED lamp, include the shell of an end opening, circuit board in the enclosure is set, coupled LED, be set in astigmatism cup and cover plate on the LED, it is characterized in that: also be provided with open-topped heat dissipating housing between described shell and the cover plate, wherein, described circuit board is arranged under the bottom of this heat dissipating housing, described LED is arranged on the bottom inside of this heat dissipating housing, and the opening part of described astigmatism cup just in time is positioned at the opening part inboard of described heat dissipating housing, and described cover plate then covers on this heat dissipating housing opening part.
Like this, LED and astigmatism cup all are positioned within the heat dissipating housing, fixed installation for ease of the astigmatism cup, prevent that it is loosening, the opening part of described astigmatism cup can be provided with a circle outward flange, and the circle step that is provided with of the opening part correspondence of described heat dissipating housing is established for the outward flange card of astigmatism cup, like this, during assembling, the outward flange of astigmatism cup just in time is positioned on that circle step of heat dissipating housing, and cover cover plate again and make it be fixed on the opening part of heat dissipating housing by screw this moment, the astigmatism cup is fixed within the heat dissipating housing, and the astigmatism cup can not rock at all.
Common light fixture, as shot-light, Down lamp, it is many that its side wall of outer shell generally is with the axisymmetric ring-type in center, for making the light fixture profile more neat and artistic, described heat dissipating housing also has annular sidewall, and the opening edge of bottom periphery size and described shell matches shell and heat dissipating housing along adapting on Outside Dimensions, linear smoothness is crossed along slipping in both junctions from the outside.
Described heat dissipating housing can adopt existing various technology, such as at a plurality of ring-types of annular sidewall arranged outside of heat dissipating housing or the convex tendon of longitudinal strip, reach the purpose of heat radiation by a plurality of convex tendons and contacting of outside air, but because of the annular sidewall of heat dissipating housing is closed, be unfavorable for that still the LED that is enclosed in heat dissipating housing inside breathes freely, therefore, for making it have better radiating effect, can offer a plurality of through holes on the annular sidewall of described heat dissipating housing, like this, the inside of heat dissipating housing and air outside just can directly see through this through hole and circulate, and realize good heat radiation purpose.
Through hole on the above-mentioned heat dissipating housing annular sidewall can be an Any shape, and any-mode is distributed on the annular sidewall, but be further to improve radiating effect, through hole on the described heat dissipating housing annular sidewall is along this heat dissipating housing strip through hole axial, that also evenly be provided with at interval, like this, evenly spaced strip through hole is separated into a plurality of sheet convex tendons to the annular sidewall of heat dissipating housing, and these convex tendons connect one because of the top and bottom plane of heat dissipating housing, and make heat dissipating housing have penetrating effect, be highly susceptible to circulation of air.
Compared with prior art, the utility model is by setting up heat dissipating housing between shell and cover plate, the heat that produces when by heat dissipating housing LED being worked directly is dispersed among the air in the heat dissipating housing external world, simple in structure, and make original high-powered LED lamp have comparatively desirable radiating effect, make the temperature in the light fixture remain on the normal temperature constant state that uses of LED, use the fault that also can not cause brightness decay or LED to damage that take place the service life of having improved light fixture greatly for a long time; And, by on the heat dissipating housing annular sidewall, evenly offering the strip through hole, help the good circulation of air of the inside and outside formation of heat dissipating housing, further strengthened radiating effect; The utility model is simple in structure, be easy to produce assembling, and light fixture is peripheral, and the lines flow smoothly, and is moulded clean and tidy, attractive in appearance.
