Abstract

The utility model discloses an LED down lamp which comprises an aluminum installation seat and an LED light source assembly, wherein the aluminum installation seat adopts a bowl-shaped opening structure; the LED light source assembly is fixed at the upper end of an inner cavity of the LED down lamp; LED light emitting units are distributed on a circumference of the LED light source assembly uniformly and circularly, and the middle part of the LED light source assembly is hollowed out; the LED down lamp also comprises an aluminum reflecting cover adopting a bowl-shaped opening structure; and the lower end of the aluminum reflecting cover is embedded in the middle hollowed-out position of the LED light source assembly and is fixed at the upper part of the inner cavity of the aluminum installation seat through a bolt. Light emitted by the LED light emitting units forms spaces in the inner side of the aluminum installation seat and the outer side of the aluminum reflecting cover, then is reflected repeatedly, and radiates out of the lamp from a hollow position formed by the aluminum installation seat and the aluminum reflecting cover. According to the LED down lamp, the light illumination angle is increased, the light-emitting surface is wider, the uniformity is degree is increased, and the down lamp has higher brightness and light-emitting efficiency.

Description

A kind of LED Down lamp

Technical field

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

Background technology

Down lamp is a kind of lighting that is embedded into light down-ejection type in ceiling, generally in hotel, family, coffee shop use more.Its maximum characteristics are exactly to keep the integral body of building decoration unified and perfect, can not destroy because of the setting of light fixture the perfect unity of furred ceiling art.This hidden the putting property light fixture that is flush-mounted in ceiling inside, all light is projection downwards all, belongs to direct luminous intensity distribution, can, with different reflectors, eyeglass, shutter, bulb, obtain different light effects.Down lamp does not take up space, and can increase the soft atmosphere in space, if want to build warm sensation, can try to install many Down lamps, alleviates space constriction.

Society, the development of lighting is more and more rapider, and the parent that the LED lamp also obtains more and more people looks at, and gradually replaces traditional lighting at present.At present, the LED Down lamp on market, be all the directional type lighting, only has its opposite just can be subject to light, and light is more concentrated, and light efficiency is poor.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of luminous wide, LED Down lamp that luminous efficiency is high is provided

The purpose of this utility model is achieved through the following technical solutions:

A kind of LED Down lamp, comprise the aluminum mount pad that is bowl-shape hatch frame and the LED light source assembly that is fixed on its inner chamber upper end, on the circumferential edge of described LED light source assembly, even ring-type is distributed with LED luminescence unit and middle part hollow out, described LED Down lamp also comprises the aluminum reflection shield that is bowl-shape hatch frame, and the lower end of described aluminum reflection shield embeds the hollow out position, middle part of described LED light source assembly and is bolted on aluminum mount pad inner chamber upper end.The interior volume that the light that the LED luminescence unit sends forms in the inboard of aluminum mount pad and the aluminum reflection shield outside through reflection repeatedly and refraction, from both, form again vacancy inject to the outside of light fixture, the illumination firing angle of LED Down lamp increases, light-emitting area is wider, the uniformity increases, and has higher brightness and luminous efficiency.

Preferably, described aluminum mount pad inboard is coated with reflective membrane, and the outside of described aluminum reflection shield is coated with reflective membrane.Reflective membrane has increased the reflected intensity of LED light, can effectively improve the utilization ratio of light.

As a kind of improvement of the present utility model, described aluminum mount pad comprises rounded pedestal part and is the reflective board of bowl-shape opening, the first reflecting piece that the multi-disc that comprises described reflective board is rectangle, described the first reflecting piece distributes and joins end to end into a circle along the even circumferential of described pedestal part.

As another kind of improvement the of the present utility model, described aluminum reflection shield comprises rounded baseplate part and is the reflective sidepiece of bowl-shape opening, the second reflecting piece that the multi-disc that comprises described reflective sidepiece is rectangle, described multi-disc the second reflecting piece distributes and joins end to end into a circle along the even circumferential of described baseplate part.

Because the aluminum mount pad is evenly arranged a plurality of identical reflecting piece with the aluminum reflection shield along its circumferencial direction, form an angle between the multi-disc reflecting piece, the light that the LED light source assembly sends increases through reflection repeatedly and the refract light illumination angle of reflecting piece, realized the scattering of light, the uniformity increases, and has increased the illuminance of light.

The utility model has the following advantages and beneficial effect compared to existing technology:

1, the interior volume that the light that the LED luminescence unit sends forms in the inboard of aluminum mount pad and the aluminum reflection shield outside through reflection repeatedly and refraction, from both, form again vacancy inject to the outside of light fixture, the illumination firing angle of LED Down lamp increases, light-emitting area is wider, the uniformity increases, and has higher brightness and luminous efficiency.

2, the LED light source assembly is arranged on the interior volume formed in inboard and the aluminum reflection shield outside of aluminum mount pad, and from the front of light fixture, LED light source is invisible, in the process of using, the consumer can only see the light beam that the aluminum mount pad reflects, and prevents dazzlingly, promotes the user and experiences.

The accompanying drawing explanation

The decomposition texture schematic diagram that Fig. 1 is the present embodiment.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.

Embodiment

As shown in Figure 1, the present embodiment provides a kind of LED Down lamp, comprise the aluminum mount pad 1 that is bowl-shape hatch frame and the LED light source assembly 2 that is fixed on its inner chamber upper end, on described LED light source assembly 2 middle part hollow outs and its circumferential edge, even ring-type is distributed with LED luminescence unit 3, described LED Down lamp also comprises the aluminum reflection shield 4 that is bowl-shape hatch frame, and the lower end of described aluminum reflection shield 4 embeds the hollow out position, middle part of described LED light source assembly 2 and is bolted on aluminum mount pad 1 inner chamber upper end.The interior volume that the light that the LED luminescence unit sends forms in the inboard of aluminum mount pad and the aluminum reflection shield outside through reflection repeatedly and refraction, from both, form again vacancy inject to the outside of light fixture, the illumination firing angle of LED Down lamp increases, light-emitting area is wider, the uniformity increases, and has higher brightness and luminous efficiency.
