There are the following problems for existing LED Down lamp:

1. existing LED Down lamp is main mainly with metal material, and metal cost is high, and weight is large, poor insulativity, if plastic cement material LED Down lamp can not meet radiating requirements again, the bad meeting of dispelling the heat affects lamp life greatly, even can damage.

2. existing LED Down lamp is luminous in the majority with downward back, so lamp body is high, and installing space is had to certain requirement and non-uniform light.

3. existing LED Down lamp be take external driving power as main, and external driving cost is high, and efficiency is on the low side, and inconvenience is installed.

Existing LED Down lamp product majority have general assembly head of screw and spuious auxiliary expose impact attractive in appearance.

Summary of the invention

The present invention has overcome the deficiencies in the prior art, provides a kind of package assembly simple, and weight is slim and graceful, is easy to install, and outward appearance is succinct without spuious auxiliary, built-in aluminium matter member heat radiation, the ultra-thin Down lamp of integral LED of the non-insulating power supply of employing low-cost high-efficiency.

The invention provides the ultra-thin Down lamp of a kind of LED, comprise face ring, diffusion barrier, LGP, reflective sheeting, LED light source, heat conduction adhesive tape, aluminium dish, insulating trip, trip bolt, LED driver, electric wire, encapsulate spring, bonnet, power line, hand terminal board, pressure-ray film and line pressing bolt.

Further, described power line is connected to LED driver input.

Further, described LED driver is fixed on bonnet with trip bolt.

Further, described power line is through bonnet hole, and by pressure-ray film, line pressing bolt is fixed on bonnet, then takes over pressure type terminal board and forms a power supply module.

Further, described LED light source is installed to aluminium dish side and fixes with heat conduction adhesive tape.

Further, described reflective sheeting, LGP, diffusion barrier is positioned in aluminium dish successively.

Further, described aluminium dish is again in placed side ring, and insulating trip attaches aluminium panel surface and forms a light source assembly.

Further, described LED driver connects LED light source by electric wire.

Further, described bonnet and face ring convex-concave closely screw fixing.

Further, described encapsulate spring fitting is on rear lid support.

The ultra-thin Down lamp of LED of the present invention has following benefit.

1) the face ring of the ultra-thin Down lamp of LED of the present invention and bonnet all adopt common heat-resisting plastic cement material, and casing insulation is good, high safety.Down lamp with respect to metal material or heat-conducting plastic material, provides cost savings.

2) the face ring upper groove of the ultra-thin Down lamp of LED of the present invention and bonnet convex platform closely screw, and easy assembly and disassembly, increase work efficiency, and reduce assembly cost, without general assembly head of screw and spuious auxiliary, expose, and outward appearance is succinctly integrated.

3) the built-in aluminium matter of the ultra-thin Down lamp of LED of the present invention discoid component, thus radiating requirements guaranteed.

4) the non-insulating power supply of the built-in high efficiency of the ultra-thin Down lamp of LED of the present invention, improves Luminaire efficiency, reduces costs.

5) the ultra-thin Down lamp of LED of the present invention adopts side entering type luminous, and luminous evenly soft, lamp body is slim and graceful, lower to the requirement of installing space.
