Abstract

The utility model discloses a novel LED tube lamp. The novel LED tube lamp comprises a lamp body outer shell, a milky reflection cup located inside the lamp body outer shell, an LED light-emitting module arranged at the bottom of the reflection cup and a light permeating cover arranged on the opening portion of the reflection cup. The novel LED tube lamp is characterized in that the light permeating cover is formed in an injection moulding mode at a time through the Fresnel lens technology, the outer surface of the light permeating cover is a smooth surface, and the inner surface of the light permeating cover is provided with equidistant tooth lines formed by concentric circles with the sizes from small to large according to light ray receiving angle demands. The Fresnel lens technology in the field of cameras is ingeniously improved and applied to the light permeating cover of the tube lamp, so that after the light ray is emitted from the LED light-emitting module to the light permeating cover, the light ray is specifically refracted because the light permeating cover is designed based on the Fresnel lens technology, the light ray is projected to a working surface needing to be irradiated on the lamp according to the designed angles instead of original diffusion after the light ray permeates a cover, and the illumination of the working surface is greatly improved.

Description

Novel LED down lamp

Technical field

The utility model relates to field of light fittings, particularly a kind of Novel LED down lamp.

Background technology

The LED Down lamp reaches the heating advantage such as low less because it has low-voltage driving, power consumption, can significantly improve service life and the luminous efficiency of light source, so use comparatively extensive.But existing LED Down lamp as shown in Figure 3, owing to problems such as its diffuser adopt simple plane milky lampshade mostly, and the ubiquity lampshade plate is too saturating, and light source comes clearly into view, and is dazzling, is difficult to satisfy consumers in general's requirement.So someone adopts diffuser is made the prism plate structure, as done pelerine design, hexagon diamond decorative pattern or pagoda shape decorative pattern etc. at the prism plate, so that it reaches atomizing and the good characteristics of light source diffusion, the Down lamp of this structure, although spot light be can't see with not dazzling when using, to depart from the refraction angle of luminous main shaft of LED illuminating module large but the diffuse reflection angle that but has light reaches greatly light that the prism plate reflects, cause light utilization efficiency low, the problems such as the light that projects on the main working face of user work is not enough, and work illumination is low.

Summary of the invention

The purpose of this utility model is for above-mentioned existing problems and deficiency, provides a kind of and both used comfortablely, can greatly improve again the ratio of the efficient light that is used for face lighting that light fixture output comes simultaneously, so that the light fixture Novel LED down lamp of efficient energy-saving more.

The technical solution of the utility model is achieved in that

Novel LED down lamp described in the utility model, comprise the lamp body shell, be positioned at the lamp body shell milky white reflector, be installed on the LED illuminating module of described reflector bottom and be installed on the diffuser of reflector oral area, it is characterized in that it is the light face that described diffuser adopts the outer surface of Fresnel Lenses technology once injection moulding, and inner surface there is the concentric circles by from small to large that designs by the requirement of light receiving angle to form equidistant groove.

The utility model is owing to adopt the light-passing board structure of diffuser being made the Fresnel Lenses formula, the FresneI(Fresnel that will be widely used at present dexterously the camera field) lens technologies. the process improvement application is to the diffuser of Down lamp product, thereby after light is emitted from the LED illuminating module, to the diffuser place, because diffuser is through the Fei Ninie Technology design, light has been carried out specific refraction, so that light is pressed the angle (rather than original diffusion) that designs after seeing through lampshade, project on the working face that light fixture will shine, so greatly improved the illumination of working face.That is to say by the control of this Novel diffuser to light, greatly improved the ratio of the efficient light that is used for face lighting that light fixture output comes, so that light fixture efficient energy-saving more.

The utility model Novel LED down lamp, the concentrically ringed radius at described diffuser center is 3-15mm, and the angle of the formed sawtooth pattern groove of adjacent two concentric circles is the 20-50 degree.The outer surface of wherein said diffuser has the concentric circles by from small to large that designs by the requirement of light receiving angle to form for light face inner surface is one-body molded equidistant groove.The angle of sawtooth pattern groove is different between concentrically ringed radius and two concentric circles, makes the formed irradiation working face of light fixture also different.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described, such as Fig. 1-shown in Figure 2, Novel LED down lamp described in the utility model, comprise lamp body shell 4, be positioned at lamp body shell 4 milky white reflector 2, be installed on the LED illuminating module 1 of described reflector 2 bottoms and be installed on the diffuser 3 of reflector 2 oral areas, it is characterized in that it is the light face that described diffuser 3 adopts the outer surface of Fresnel Lenses technology once injection moulding, and inner surface there is the concentric circles 31 by from small to large that designs by the requirement of light receiving angle to form equidistant groove.The FresneI(Fresnel that will be widely used at present dexterously the camera field) lens technologies. the process improvement application is to the diffuser of Down lamp product, thereby after light is emitted from LED illuminating module 1, to diffuser 3 places, because diffuser 3 is through the Fresnel Technology design, light has been carried out specific refraction, so that light is pressed the angle (rather than original diffusion) that designs after seeing through lampshade, project on the working face that light fixture will shine, so greatly improved the illumination of working face.That is to say the control by 3 pairs of light of this Novel diffuser, greatly improved the ratio of the efficient light that is used for face lighting that light fixture output comes, so that light fixture efficient energy-saving more.The concentrically ringed radius at described diffuser 3 centers is 3-15mm, and the angle of the formed sawtooth pattern groove of adjacent two concentric circles is the 20-50 degree.The outer surface of wherein said diffuser has the concentric circles by from small to large that designs by the requirement of light receiving angle to form for light face inner surface is one-body molded equidistant groove.The angle of sawtooth pattern groove is different between concentrically ringed radius and two concentric circles, makes the formed irradiation working face of light fixture also different.

Be applied to the model machine that the utility model design is produced, our design lamps is that 60 degree are luminous, and the light that namely sees through diffuser is designed to become 30 to spend the angle refraction with the main light emission axle.Through test, the illumination of working plane of 2.5M has improved more than 2 times;

Simultaneously, by the design to the different lighting angle of diffuser, can reach from any lighting angle of 0-120 degree, we are designed to desirable lighting angle between 60 degree-80 degree; Can be applied to from the throw light on field of accent light of basal plane; Because the Fresnel Lenses technology that the utility model adopts, diffuser is disposable injecting products, and it is low to have a cost, and the high advantage of homogeneity of product, suits large area to popularize; Can be widely used in the market, hotel.

Although the utility model is to describe with reference to specific embodiment, this description and not meaning that is construed as limiting the utility model.With reference to description of the present utility model, other of the disclosed embodiments change, and all can expect for those skilled in the art, and this variation should belong in the affiliated claim limited range.
