Abstract

The utility model discloses a LED down lamp for illumination, which comprises a LED lamp panel, a reflection cup, a face ring on one end of the reflection cup and a radiator on the other end of the reflection cup, wherein the face ring, the reflection cup and the radiator are fixed together through a clip and the reflection up is equipped with a bottom surface. The LED down lamp in the utility model has a technical effect that heat is generated from the LED lamp panel by the reflection cup set on the bottom and transmitted to the radiator through the bottom of a reflection lamp, so that better thermal dissipation effect is obtained.

Description

LED Down lamp

Technical field

The utility model relates to a kind of light fixture, particularly LED Down lamp.

Background technology

LED Down lamp is except having energy-conserving and environment-protective, and the long general advantage of LED lamp that waits of life-span, also keeps the integral body of building decoration unified and perfect because its light and handy design attractive in appearance makes can reach when mounted, and be subject to liking of more and more people.But owing to being subject to the restriction of LED principle of luminosity, its caloric value is larger, if radiating effect is bad, will reduce its service life.LED Down lamp mainly dispels the heat by radiator and reflector at present, and reflector is made by the good aluminum material of thermal diffusivity, and its area is larger, and thermal diffusivity is better.

Summary of the invention

The purpose of this utility model is to provide a kind of excellent heat dissipation performance and LED Down lamp simple in structure in order to solve above-mentioned the deficiencies in the prior art.

To achieve these goals, the LED Down lamp that the utility model is designed, comprise LED lamp plate, reflector, and at the face ring of reflector one end with at the radiator of the reflector other end, face ring, reflector and radiator are fixed together by shell fragment, on reflector, be provided with bottom surface, on the bottom surface of reflector and LED lamp plate opposite position, be provided with the through hole passing for screw, by screw, described LED lamp plate and reflector bottom surface are fixed on the end face of radiator.

The LED Down lamp that the utility model obtains, its technique effect is by being provided with the reflector of bottom surface, the heat of LED lamp plate generation to be delivered on radiator by reflector lamp bottom surface, thereby reaches better radiating effect.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment 1:

As shown in Figure 1, Figure 2, Figure 3 shows, the LED Down lamp that the utility model provides, comprise LED lamp plate 1, reflector 2, and at the face ring 3 of reflector 2 one end with at the radiator 4 of reflector 2 other ends, face ring 3, reflector 2 and radiator 4 are fixed together by shell fragment 5, as described in Figure 4, described reflector 2 is provided with bottom surface 7; On the bottom surface 7 of described reflector 2 and on the opposite position of LED lamp plate 1, be provided with the through hole 6 passing for screw, by screw, described LED lamp plate 1 and reflector bottom surface 7 be fixed on the end face of radiator 4.

In concrete installation process, first with screw, shell fragment 5 is fixed on radiator, now form the cavity of a truncated cone-shaped, again reflector 2 is put into this cavity, then face ring 3 is covered on reflector 2, with screw, the middle-end of shell fragment 5 is fixed on face ring 3, finally with screw, described LED lamp plate 1 and reflector bottom surface 7 is fixed on the end face of radiator 4.
