Description

The LED Down lamp

Technical field

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

Background technology

Down lamp is a kind of being embedded in the ceiling, the lighting of penetrating under the light.Characteristics such as led light source is nontoxic because of its no mercury, no electromagnetic pollution, no harm ray and energy-conserving and environment-protective, long service life are widely used, and the part Down lamp also uses LED as light source.But characteristics such as led light source has, and exiting surface is little, light intensity distributions is concentrated, directive property is strong, thereby cause the illumination light intensity distributions of LED Down lamp inhomogeneous, illumination zone is little, brightness concentrations, decorative effect are poor, can't satisfy people's normal lighting needs; And the light that led light source sends is very dazzling, has glare phenomenon, and is bigger to the eye health influence.

Summary of the invention

The main purpose of the utility model provides a kind of LED Down lamp, is intended to realize that the light that LED lamp pearl sends is soft, and increases the irradiating angle of the light that LED lamp pearl sends, and increases illumination zone, improves the utilization rate of the light that sends.

The utility model proposes a kind of LED Down lamp; Comprise that aluminium base, radiator and a bottom that some LED lamp pearls are installed are provided with the lampshade of through hole; Said aluminium base is fastened on the end face of said radiator; The end that said radiator is connected with said aluminium base is connected with said lampshade through said through hole; Said aluminium base places in the said lampshade through said through hole, one be used for divergent rays diffuser cover on the said through hole and, on said diffuser internal face, be stained with a glass layer of sand with said LED lamp pearl cover within it.

Preferably, said glass layer of sand inwall is covered with a phosphor powder layer.

Preferably, evenly be provided with several reflective salient points on the internal face of said lampshade.

Preferably, but the bowl structure body that said lampshade is processed for Heat Conduction Material, and said diffuser is hemispherical.

Preferably, said aluminium base is fixed by welding on the end face of said radiator, and the end that said radiator is connected with said aluminium base is provided with the periphery that is provided with around said aluminium base, and inside and outside surface, said periphery is respectively equipped with first screw thread, second screw thread; Said through hole internal diameter and said peripheral external diameter are adaptive; The opening part external diameter of said diffuser and said peripheral internal diameter are adaptive; Be provided with three screw thread adaptive in the said through hole, be provided with four screw thread adaptive in the said opening part with said first screw thread with said second screw thread.

The LED Down lamp of the utility model comprises one with LED lamp pearl cover diffuser within it, is stained with a glass layer of sand on the internal face of diffuser, when the light that LED lamp pearl sends passes through the glass layer of sand on the diffuser; Refraction and scattering take place; Light disperses, and can not form concentrated luminous point ejaculation and go, and light is even, soft; Go out through lampshade is reflective again from the light that diffuser transmits; And evenly be provided with several reflective salient points on the internal face of lampshade, can increase the angle that light penetrates, the utilization rate of the light that raising LED lamp pearl sends.

The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.

The specific embodiment

Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

With reference to Fig. 1, Fig. 2 and Fig. 3, an embodiment of the LED Down lamp of the utility model is proposed, comprise that aluminium base 30, radiator 10 and a bottom that some LED lamp pearls 301 are installed are provided with the lampshade 20 of through hole.Radiator 10 is cylindric, and aluminium base 30 is fixed by welding on the end face of radiator 10, and the end that radiator 10 is connected with aluminium base 30 is provided with the periphery that is provided with around aluminium base 30, and peripheral inside and outside surface is respectively equipped with first screw thread, second screw thread.This lampshade 20 is bowl-shape; On the internal face of lampshade 20, evenly be provided with several reflective salient points 201; It is adaptive to be located at rounded and its internal diameter of the through hole of lampshade 20 bottoms and peripheral external diameter; Be provided with three screw thread adaptive at the manhole madial wall with second screw thread; Radiator 10 is connected with an end of aluminium base 30 through through hole, through rotation second screw thread and the 3rd screw thread is mutually combined between lampshade 20 and the radiator 10, and is fixing thereby an end that makes lampshade 20 and radiator 10 be connected with aluminium base 30 is connected.

Aluminium base 30 places in the lampshade 20, one be used for divergent rays diffuser 40 cover on the through hole and with LED lamp pearl 301 covers within it, this diffuser is the transparent body, the internal face of diffuser is astigmatic face.Diffuser 40 is hemispherical; Bottom at diffuser 40 is provided with opening; The opening part external diameter and the peripheral internal diameter of diffuser 40 are adaptive; Be provided with four screw thread adaptive in the opening part, through rotation first screw thread and the 4th screw thread mutually combined between diffuser 40 and the radiator 10 with first screw thread, fixing thereby an end that makes diffuser 40 and radiator 10 be connected with aluminium base 30 is connected.On diffuser 40 internal faces, be stained with a glass layer of sand 401; Can effectively improve the diffusion rate of light during light process glass layer of sand 401; Thereby obtain radiation response more uniformly; Be covered with a phosphor powder layer at glass layer of sand 401 inwalls, phosphor powder layer can make the light that reflects from glass layer of sand 401 softer.When the light that LED lamp pearl 301 sends passes through the glass layer of sand 401 on the diffuser 40 astigmatic faces, refraction and scattering take place, light disperses; Can not form concentrated luminous point ejaculation goes; Light is even, and the light that reflects from glass layer of sand 401 shines out through phosphor powder layer, and light is softer; The light that transmits from diffuser 40 passes through lampshade 20 reflective going out again; And evenly be provided with several reflective salient points 201 on the internal face of lampshade 20, can increase the angle that light penetrates, the utilization rate of the light that raising LED lamp pearl 301 sends; Thereby the light that shines out does not have dazzle property; Can be not dazzling, can effectively improve the drawback of luminous solar flare of the luminous generation of LED and strong dazzling light, improved the brightness of illumination of LED simultaneously.

But the bowl structure body that lampshade 20 is processed for Heat Conduction Material, lampshade 20 combines with radiator 10 and dispels the heat with radiator 10, improves radiating rate.

The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
