(2) power supply independently is provided with, and the installation site can be selected flexibly, and is easy for installation;
(3) the power supply module does not seal, and glue shell perforate up and down ventilates, good heat dissipation, thus improve the whole lamp life-span;
(4) aperture on the said aluminium matter panel can be hung and hang light sequin and decorate festive air, satisfies client's diversified demand;
(5) the compatible plurality of LED light sources of said Down lamp internal structure, light is soft, even, shadow-free, does not have obvious dazzle, and not dazzling, light efficiency is higher.
Description of drawings
Fig. 1 is said LED Down lamp example structure decomposing schematic representation; Fig. 2 is said LED Down lamp embodiment overall structure figure; Fig. 3 is that said LED Down lamp embodiment aluminium matter panel is overhanging along structure chart; Fig. 4 is said LED Down lamp embodiment cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done detailed explanation.
The LED Down lamp that present embodiment disclosed shown in accompanying drawing 1-4, comprises heat dissipating housing 6; Be provided with the aluminium base 5 that led light source is installed in the heat dissipating housing 6; Heat dissipating housing 6 inner surfaces are provided with the PET reflecting piece 4 of high reflectance, and the bottom is provided with high transmission rate diffuser plate 3, and the light part sent of led light source directly penetrates through the high transmission rate diffuser plate like this; Another part is incident upon the PET reflecting piece of heat dissipating housing inner surface, and the overwhelming majority also can reflex to high transmission rate diffuser plate 3 and exhale.Be provided with the aluminium matter panel 1 of auxiliary heat dissipation in the heat dissipating housing lower end; Aluminium matter panel 1 top is annular, and this annular connecting portion is connected with the annular of heat dissipating housing bottom, also evenly is provided with radiating fin on the annular connecting portion 11; Annular connecting portion lower end is provided with overhanging edge 12, and overhanging edge is provided with air-vent 13.This aluminium matter panel 1 is installed on heat dissipating housing 6 lower ends through screw, and above-mentioned high transmission rate diffuser plate is installed in the standing groove of aluminium matter panel 1.
Because it is lower that the degree of protection of indoor lamp requires, and utilizes this point, Down lamp described in the utility model is divided into two to heat dissipation region, i.e. aluminium matter panel 1 and fin 6.Led light source and aluminium base 5 are locked at baseplane in the heat dissipating housing 6, and the centre has heat-conducting silicone grease to fill.The thermal source of LED generation is evenly derived by heat-conducting silicone grease and is shed through heat dissipating housing 6 like this.Because most of Down lamp is perpendicular to ground or flooring and is embedded in the ceiling; Aluminium matter panel 1 overhanging many groups air-vent along setting is exposed on the smallpox surface; Be used for cross-ventilation, air-vent flows into air continually, forms good convection current with air in the sealing ceiling.
The power supply module of said Down lamp is designed to independently module; The plastic cement loam cake 10 that has through hole can be buckled on the power supply plastic cement bottom 7 through screens; Wiring end cap 15 adopts screens to insert on the power supply plastic box loam cake 10, can release with it and separate, to make things convenient for terminal use's installation connection.The power supply plastic box adopts fire prevention PC material; Whole power pack can be fixed on (also detachable installation) on the heat dissipating housing 6 through screw, and heat dissipating housing 6 leaves the adequate ventilation space with the power supply faying face, is provided with a lot of air-vents above the power supply plastic box loam cake 10 and is convenient to cross-ventilation; Therefore the power supply space does not form sealing; Environment temperature significantly reduces, and adds convection current, make in the power supply module components and parts particularly the temperature of IC and electrochemical capacitor can decline to a great extent.
Aluminium matter panel 1 is overhanging along the many groups air-vent that is provided with, and can also be used to hanging and hangs light trinket, and like balloon, ornaments such as colored ribbon are decorateeed atmosphere, satisfy client's diversified demand.
Shown in accompanying drawing 2; Heat dissipating housing 6 is reserved enough height space and is used for compatible various led light source; No matter use which kind of led light source; Cooperate the PET reflecting piece 4 of high reflectance can guarantee that all the light high-quality overflows, avoid shade, brilliant white hot spot point, phenomenon such as dazzling, can improve 20% luminous flux and illumination simultaneously.
In addition; Aluminium matter panel 1 Shanghai is provided with two shell fragment seats; Insert structure Laian County dress Spring sheet clip 2 of captive screw in these two shell fragment seats adopt, good Spring sheet clip mounting structure can make this light fixture be clipped in for a long time and still remain on high strength and solid state in the ceiling.
The foregoing description is merely the preferred implementation of the utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection domain of the utility model.
