Description of drawings

Fig. 1 is the exploded view of LED cabinet lamp among the utility model embodiment;

Fig. 2 is an I portion enlarged drawing among Fig. 1;

Fig. 3 is the extension corner structure figure of LED cabinet lamp among the utility model embodiment.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

LED cabinet lamp as shown in Figure 1 comprises aluminium section bar lamp housing 1, is fixed on the pcb board 2 on the outer wall of said aluminium alloy extrusions lamp housing 1 through bond plies; Be connected electrically in the led light source 3 on the PCB circuit board 2; Be located at the lampshade 7 outside the led light source 3, be arranged on the plug 4 of aluminium section bar housing 1 right ends, be arranged on the human inductor 5 on the aluminium section bar housing 1; Be arranged on the inductive probe 6 of human inductor 5, the extension angle 8 that can be fixed with aluminium section bar housing 1.

In the present embodiment, aluminium alloy extrusions lamp housing 1 adopts the aluminium alloy one-shot forming; Aluminium section bar housing both sides of the edge are provided with groove 11, and the thermal conductivity factor of the material selection of aluminium alloy lamp housing itself is higher, has adopted anode oxidation process; It has improved the wear resistence of aluminium section bar; Corrosion resistance and insulating properties, simultaneously the oxide-film on surface can anti-600 degrees centigrade high temperature, and outward appearance also can be guaranteed; Simultaneously heat radiation is had tangible reinforcement, thereby it has solved the not good short problem in service life that causes of existing LED light fixture radiating effect.The heat that when this each led light source is luminous, is produced dissipates to the external world with the mode of free convection and conduction from bottom to top by air and is dissipated in the ambient air; Descend because of the overheated led light source luminous power that causes with elimination; Colour temperature is elegant, and then influences the problem of brightness of illumination.The mechanical performance of superelevation, the thermal conductivity factor of superelevation, heat conduction, heat radiation, convection current is with the obvious advantage, the radiating effect persistent high efficiency, long service life, good looking appearance obviously improves the configuration design space and the external aesthetic property of LED light fixture, and consumer's acceptable degree is high.

Plug 4 has adopted wear-resisting, and heat distortion temperature is higher and flame retardant rating is higher PBT material constitutes, and the plug indoor design has been adopted to carry the mounting means that the shell fragment down is gone into is installed; Exempted screw and fixed, also need not play glue, fit has been simplified in fixed form this measure of comparing in the past; Accelerated assembling speed; It is little to be prone to assembling and rigging error, has improved production efficiency, has also improved safety coefficient when letting firm firm that structure becomes accordingly.The PBT plug divides public female, can connect certainly through interconnection line, can single driving, and also can be through the interconnected formation lamp of special-purpose tie group, system drive.

Lampshade 7 has been selected optical grade PMMA lampshade for use, has added anti-UV in this lampshade, and is anti-oxidant, the anti-aging material of Denging; Prevent that light fixture from lighting for a long time, the lampshade jaundice, high temperature resistant 135 degree that reach, light transmittance is up to more than 92%; Light loss is little, and what itself adopt is milky, and the effective like this LED that prevented dazzles the uncomfortable degree that light causes human eye; And light loss is little, and illumination is even, and visual effect is very good.

Hanging angle 8 has also selected for use wear-resisting; Corrosion-resistant; The PBT material that heat distortion temperature is higher and flame retardant rating is higher is hung the bottom, angle and is had a screw hole 81, and respectively there is an outstanding small stair 82 the Gua Jiao two sides; When tightening with cabinet lamp aluminium section bar housing; The groove 11 of its ability and aluminium section bar lamp housing both sides of the edge has an engaged effect, stings tightly and can play a fixing effect to whole lamp afterwards, to such an extent as to can and when need not fixing, can the cabinet lamp be taken out easily cabinet lamp chucking.Earlier the cabinet lamp being hung the angle chucking is fixed on the cabinet lamp; No matter will hang angle 8 with tapping screw 9 again and be fixed between kitchen cabinet, be at the cabinet wall, still pushes up at cabinet; This mounting means can be well fixing with the cabinet lamp, thus the environment for use and the field of employment of having improved LED cabinet lamp greatly.
