Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of LED light fixture based on the cold-hot air convection heat radiation that does not need extra radiator can effectively reduce the LED temperature.
The present invention solves the technical scheme that its problem adopts:
A kind of LED light fixture based on the cold-hot air convection heat radiation, comprise the LED housing and be arranged at the interior LED luminescence unit of LED housing, have on the described LED housing for first heat radiation that enters for cool ambient air and dispel the heat to discharge orifice to discharge orifice with for second of hot-air discharge in the LED housing, described first heat radiation is gone into the heat radiation convection channel that hot-air goes out from the second heat radiation convection current orifice flow to discharge orifice and the second heat radiation convection current hole formation cold air from the first heat radiation convection current orifice flow.
Further, described first heat radiation is respectively arranged with a plurality of to discharge orifice and second heat radiation to discharge orifice.By a plurality of first heat radiations being set to discharge orifice and the second heat radiation convection current, can strengthen radiating effect of the present invention.
Further, described first dispels the heat is arranged on the place ahead of LED housing to discharge orifice, and described second heat radiation is arranged on the rear of LED housing to discharge orifice.
The invention has the beneficial effects as follows: a kind of LED light fixture based on the cold-hot air convection heat radiation that the present invention adopts, the LED luminescence unit can produce higher heat, and the luminous institute that heat mainly is created in the LED luminescence unit on the whole, because the air of LED luminescence unit light-emitting area one side is warmmer, opposite side is then colder, therefore, convection effect based on hot cold air, hot-air can flow to the cold air direction, form the effect of convection current, dispel the heat to discharge orifice to discharge orifice with for second of hot-air discharge in the LED housing owing to being provided with first heat radiation that enters for cool ambient air on the described LED housing housing respectively, because the hot-air in the LED housing dispels the heat to discharging the discharge orifice from second, therefore among the cold air in the external world can enter to the LED light fixture from first heat radiation to discharge orifice, thereby form in the LED light fixture, outer cold and hot convection current, described first heat radiation has then formed the heat radiation convection channel to discharge orifice and second heat radiation to discharge orifice, when LED luminescence unit temperature is higher, because the temperature difference is big, therefore convection effects is strong, the speed that air flows is fast, heat in the LED light fixture can be discharged rapidly, at this moment the temperature of LED luminescence unit reduces, the cross-ventilation effect remains on state stably, the temperature of LED luminescence unit can be remained on low reasonable range, thereby improve the life-span of LED greatly, the present invention utilizes the height temperature difference to realize the radiating effect of cold and hot convection current, heat in the LED light fixture is discharged rapidly, do not need to arrange the temperature that extra metal heat sink or heat radiator can reduce the LED luminescence unit, thereby can save the heat radiation cost of LED light fixture, be applicable to the large-scale production of LED and the popularization of illumination LED.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and example.
Fig. 1 is structural representation of the present invention.
The specific embodiment
With reference to Fig. 1, a kind of LED light fixture based on the cold-hot air convection heat radiation of the present invention, comprise LED housing 1 and the LED luminescence unit 2 that is arranged in the LED housing 1, have on the described LED housing 1 for first heat radiation that supplies cool ambient air to enter and dispel the heat to discharge orifice 4 to discharge orifice 3 with for second of hot-air discharge in the LED housing 1, described first heat radiation flows into the heat radiation convection channel that hot-air flows out discharge orifice 4 from second heat radiation to discharge orifice 3 and second heat radiation to discharge orifice 4 formation cold airs to discharge orifice 3 from first heat radiation.Wherein said first heat radiation is respectively arranged with a plurality of to discharge orifice 3 and second heat radiation to discharge orifice 4.By a plurality of first heat radiations being set to discharge orifice 3 and the second heat radiation convection current, can strengthen radiating effect of the present invention, preferred first heat radiation is more to discharge orifice than two heat radiations to the quantity of discharge orifice 3, can strengthen cool ambient air like this and enter in the LED light fixture, improves radiating effect.
Particularly, described first heat radiation is arranged on the place ahead of LED housing 1 to discharge orifice 3, described second heat radiation is arranged on the rear of LED housing 1 to discharge orifice 4, wherein said the place ahead refers to the light emission direction of LED luminescence unit 2, because the temperature on the light emission direction of LED luminescence unit 2 is higher, therefore first heat radiation is arranged on the place ahead of LED housing 1 to discharge orifice 3, and second heat radiation is arranged on the setting of its heat radiation convection channel of rear of LED housing 1 to discharge orifice 4 the most reasonable, and its radiating effect is best.And the preferred mounting means of LED light fixture is, second heat radiation is dispelled the heat to the position height of discharge orifice 3 than first to the position of discharge orifice 4.Because the density of hot-air is little, therefore first heat radiation is arranged at than second heat radiation on the high position of discharge orifice 4 time cold and hot convection effect of easier formation to discharge orifice 3.
