Description

A kind of modified LED light fixture

Technical field

The utility model relates to a kind of lighting apparatus, particularly a kind of LED light fixture.

Background technology

The LED light fixture that people are common; Its structure generally comprises radiating seat, housing, Lamp cup, led light source module and cover; The hollow ring pedestal of this radiating seat for surrounding by some radiating fins, this housing is set in the hollow chamber of this radiating seat, and this Lamp cup is erect and is installed in this housing; This panel is installed in outside the lower end surface of this housing; And this panel is in outside the hollow chamber of this radiating seat, and this led light source module is installed on the upper end of this Lamp cup, and the light-emitting area of this led light source module is towards this panel; Offer the through hole of the light ejaculation that supplies the led light source module on this panel, offer confession led light source module is electrically connected usefulness with extraneous power supply wire guide on the upper end end face of this housing.The LED light fixture of this kind structure because its light source adopts LED, has advantages such as energy-saving and environmental protection, long service life, is widely used in the illumination of commercial location, public place and family.But the LED light fixture of this kind structure because radiating seat is located at outside the housing, is prone to influence the overall appearance of LED light fixture.

In order to address the above problem; Occurred a kind of Novel LED lamp on the market, its structure generally comprises radiating seat, housing, Lamp cup, led light source module and cover, the hollow ring pedestal of this radiating seat for being surrounded by some radiating fins; This radiating seat is installed in the chamber of this housing; This panel locking is outside the lower end surface of this housing, and this Lamp cup is erected in the hollow chamber of this radiating seat, and the bottom of this Lamp cup is fixedly connected with this panel; This led light source module is installed on the upper end of this Lamp cup; And the light-emitting area of this led light source module offers the through hole of the light ejaculation that supplies the led light source module towards this panel on this panel, offers on the upper end end face of this housing to supply the led light source module to be electrically connected the wire guide of usefulness with extraneous power supply.The LED light fixture of this kind structure because radiating seat is located in the chamber of housing, has avoided exposing because of radiating seat the problem of the overall appearance that influences the LED light fixture like this; But this kind LED light fixture because radiating seat is located in the chamber of housing, is in the airtight relatively space radiating seat, thereby the heat transfer rate of radiating seat is affected, and causes the radiating effect of radiating seat relatively poor, and then shortened the service life of LED light fixture.

In view of above-mentioned reason, the inventor furthers investigate the structure of existing LED light fixture, is then produced by this case.

The utility model content

The purpose of the utility model provides a kind of higher modified LED light fixture of heat transfer rate that makes radiating seat.

The technical scheme of the utility model is such: a kind of modified LED light fixture; Comprise radiating seat, housing, Lamp cup, led light source module and cover; The hollow ring pedestal of this radiating seat for surrounding by some radiating fins, this radiating seat is installed in the chamber of this housing, and this panel locking is outside the lower end surface of this housing; This Lamp cup is erected in the hollow chamber of this radiating seat; And the bottom of this Lamp cup is fixedly connected with this panel, and this led light source module is installed on the upper end of this Lamp cup, and the light-emitting area of this led light source module is towards this panel; Offer the through hole of the light ejaculation that supplies the led light source module on this panel, offer confession led light source module is electrically connected usefulness with extraneous power supply wire guide on the upper end end face of this housing; Offer on the above-mentioned panel and supply outside air to be blown into the fresh air inlet in the above-mentioned housing, and the place, top that the upper end of above-mentioned housing is positioned at above-mentioned radiating seat offers exhaust vent.

Above-mentioned fresh air inlet is provided with several, and each above-mentioned fresh air inlet is periphery on above-mentioned panel, and each above-mentioned fresh air inlet all is in outside the above-mentioned through hole.

Above-mentioned fresh air inlet is an ellipse hole.

Above-mentioned exhaust vent is provided with several, and each above-mentioned exhaust vent is periphery on the end face of the upper end of above-mentioned housing, and each above-mentioned exhaust vent all is in outside the above-mentioned wire guide.

After adopting technique scheme; A kind of modified LED light fixture of the utility model; Supply outside air to be blown into the fresh air inlet in the housing owing to offer on the panel, and the place, below that the upper end of housing is positioned at radiating seat offer exhaust vent, like this; Cool ambient air can flow in the housing to the radiating seat place through fresh air inlet; This moment, hot-air gently produced ascending motion because the work calories of led light source module can be passed to the radiating seat place, and the cold air that promptly flow to the radiating seat place can receive the thermosetting hot-air; Hot-air just can be positioned at the exhaust vent outflow of radiating seat top from housing; And the draft that ascending motion produced of hot-air can promote cool ambient air to be flowed into by fresh air inlet in the hollow chamber of radiating seat, forms convection current, realizes continuously in the hollow chamber of radiating seat that promptly suction cold air, cold air are heated into the process of hot-air, hot-air outflow.Compared with prior art; Air in the LED light fixture of the utility model, its radiating seat need not to adopt fan also can strengthen the strong convection effect of air in the radiating seat, can improve the heat transfer rate of radiating seat greatly; Thereby make the radiating effect of radiating seat better, and then can prolong the service life of LED light fixture.
