Fig. 3 is the said LED pendent lamp of a Fig. 1 embodiment Lamp cup structure upward view;
Fig. 4 is that the said LED pendent lamp of Fig. 3 embodiment A is to sectional view;
Fig. 5 is that the said LED pendent lamp of Fig. 4 Embodiment B is to sectional view.
The specific embodiment
For the ease of those skilled in the art will recognize that the present invention is done detailed explanation below in conjunction with accompanying drawing and embodiment.
Disclosed LED pendent lamp like Fig. 1~4, comprises messenger wire 1, plastic cement loam cake 2, plastic cement power pack 3, power supply 4, die casting shell 5, led light source and aluminium base 6, lens 7 and Lamp cup 8.Plastic cement loam cake 2 is installed on die casting shell 5 tops, and the two forms lamp head, and the LED assembly of being made up of power supply 4, led light source and aluminium base 6, lens 7 is installed in it; Lamp cup 8 is installed on die casting shell 5 belows, and whole pendent lamp is hung on the indoor smallpox top through messenger wire.
Because it is lower that the degree of protection of indoor lamp requires, so the design through hole is used to breathe freely on plastic cement loam cake 2, the plastic cement loam cake 1 that has through hole is locked on the die casting shell 5 through screw, and the die casting shell is provided with radiating fin outward.Lamp cup 8 tops are to be stuck on the die casting shell 5 through coupler construction, and Lamp cup 8 adopts the transparent PC material of atomizing, can play certain translucent effect.Like Fig. 4, Lamp cup is suitable for reading to have an annular block surface, and annular block surface interstitial hole and LED assembly lower edge (lens lower edge) agree with the LED assembly is blocked in lamp holder, and lens component exposes.This annular block surface is provided with air-vent, and the air-vent that is provided with on the plastic cement loam cake 2 of this air-vent and lamp holder makes air form the convection current of above-below direction.
The annular block surface of Lamp cup 8 is provided with two groups of holes, one group of macropore, one group of aperture; Every group of hole is the center with the annular center, and along circumferentially evenly distributed, aperture is positioned at outward flange; Macropore is positioned at inward flange, is convenient to air and enters into the LED pendent lamp from the light fixture bottom, and so led light source and aluminium base 6 have also directly formed convection current with air; Thereby also can reduce the temperature of led light source, increase led light source light efficiency and life-span.
Die casting shell 5 inner transverse are provided with one, and to have certain thickness entity face be mounting plane, is used to install the LED assembly, and mounting plane must surpass certain thickness guarantee abundant heat conduction.Power supply 4 is installed on the mounting plane top through screw, keeps certain distance between power supply 4 and the mounting plane with insulation; Led light source and aluminium base 6 lock onto the mounting plane below through screw, and the centre also keeps certain distance with insulation, and fill with heat-conducting silicone grease; Below led light source and the aluminium base 6 lens 7 are housed.
During this mounting plane design, can be designed in the structure of laterally not exclusively cutting off die casting shell 5 inner spaces, not hinder the cross-ventilation of the inner above-below direction of pendent lamp.Mounting plane is whole die casting shell 5 inner spaces that cut off in the present embodiment; But on mounting plane, offer through hole, be convenient to the installing space that air under the whole pendent lamp enters into power supply 4, fixing plastic cement power pack 3 surfaces also are provided with air-vent and are convenient to cross-ventilation above the power supply 4; The power supply space does not form and blocks like this; All ventilations up and down, a part can shed through the die casting shell after the heat that power work sends shed from the plastic cement power pack, and a part of hot-air continues to rise and discharges through the through hole on the plastic cement loam cake 2; Can make that temperature significantly reduces in it, make the power supply components and parts particularly the temperature of IC and electrochemical capacitor can decline to a great extent.
As shown in Figure 3, during use, LED assembly inner light source and power supply all produce certain heat, and this heat can conduct to die casting shell 5 through mounting plane, distribute through die casting shell 5 outside radiating fins.On the other hand; Air is that the air-vent on the Lamp cup 8 flows in the light fixture from LED pendent lamp bottom, forms convection current with led light source and aluminium base 6 earlier, also has air also to flow into power supply 4 interior volume; Carry out cross-ventilation with power supply; Through the air-vent on plastic cement power pack 3 surfaces, shed through the air-vent above the plastic cement loam cake 2 at last then, air has also effectively carried out convection current with die casting shell 5 inner walls certainly.Like this, said light fixture all can be good at heat radiation on horizontal and vertical, and radiating efficiency is high, thereby can effectively prolong led light source life-span and whole pendent lamp light efficiency.
Pendent lamp structure according to the invention also is suitable for the heat radiation that other similar degree of protection is low, allow the lamp of lamp head top perforate, is not limited to the LED pendent lamp.
The preferred version that the foregoing description is realized for the present invention, AndNon-limiting exhaustive, the present invention can also have other variations under same idea.Need to prove that under the prerequisite that does not break away from the present invention's design, any conspicuous replacement is all within protection domain of the present invention.
