Abstract

The utility model discloses a spot and anti-dazzle down lamp injection molding lampshade, wherein the down lamp comprises a lampshade arranged on a radiator, and an LED lamp panel is arranged between the lampshade and the radiator; the lampshade is an anti-dew point and anti-glare lampshade which is integrally formed by injection molding; the inner surface of the anti-dew point and anti-dazzle lampshade is an atomized surface; the outer surface of the dew point prevention and anti-glare lampshade is provided with an optical microstructure which is formed by a hexagonal pyramid array concavely arranged on the outer surface. The lampshade can achieve the purpose of reducing glare, the light distribution penetrating through the lampshade is more uniform, and LED bright spots cannot be exposed.

Description

Prevent dew point and anti-dazzle's down lamp injection moulding lamp shade

Technical Field

The utility model belongs to the technical field of lamps and lanterns illumination production, concretely relates to lamp shade structural improvement of LED down lamp.

Background

At present, an LED down lamp with anti-dazzle requirements is prepared by hiding a light source component and a lampshade in an inner part which is deeper than a light-emitting surface, wherein the deeper the distance is, the better the anti-dazzle effect is. But at the same time, the following two problems arise:

first, much light is wasted in absorption and refraction of the reflector, resulting in excessive light loss and reduced light efficiency;

secondly, the light projection angle of the lamp becomes smaller and smaller, and the use requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

For solving the problem that prior art exists, the utility model provides a prevent down lamp injection moulding lamp shade of dew point and anti-dazzle. The lampshade can achieve the purpose of reducing glare, the light distribution penetrating through the lampshade is more uniform, and LED bright spots cannot be exposed.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a kind of anti-dew point and anti-dazzle down lamp injection moulding lamp shade, the said down lamp includes the lamp shade mounted on radiator, a LED lamp board is mounted between this lamp shade and radiator; the lampshade is an anti-dew point and anti-glare lampshade which is integrally formed by injection molding; the inner surface of the anti-dew point and anti-dazzle lampshade is an atomized surface; the outer surface of the dew point prevention and anti-glare lampshade is provided with an optical microstructure which is formed by a hexagonal pyramid array concavely arranged on the outer surface.

Compared with the prior art, the utility model provides a technical scheme has following beneficial effect:

firstly, the utility model discloses the lamp shade is through direct concave optics micro-structure of establishing six pyramid arrays at injection moulding's lamp shade surface to reduce the stray light of lamp shade, reach the purpose that reduces the glare.

Secondly, through do the atomization process at the surface of injection moulding's lamp shade internal surface to break up light at the internal surface towards the LED lamp plate, make the luminous chip on the LED lamp plate look more even from the lamp shade outside, can not reveal the LED bright point.

fig. 4 is an enlarged schematic view of a portion a of fig. 1.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

In the claims, the specification and the drawings, unless otherwise expressly limited, the terms "first," "second," or "third," etc. are used for distinguishing between different elements and not for describing a particular sequence.

In the claims, the specification and the drawings, unless otherwise expressly limited, to the extent that directional terms such as "center", "lateral", "longitudinal", "horizontal", "vertical", "top", "bottom", "inner", "outer", "upper", "lower", "front", "rear", "left", "right", "clockwise", "counterclockwise" and the like are used, the positional or orientational relationships illustrated in the drawings are based on the positional and orientational relationships illustrated in the drawings and are merely for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element so referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore should not be construed as limiting the scope of the present invention in any way.

In the claims, the description and the drawings of the present application, unless otherwise expressly limited, the term "fixedly connected" or "fixedly connected" is used, which is to be understood broadly, that is, any connection mode without displacement relation or relative rotation relation between the two, that is, including non-detachably fixed connection, integrated connection and fixed connection through other devices or elements.

In the claims, the specification and the drawings, the terms "including", "comprising" and variations thereof, if used, are intended to be inclusive and not limiting.

Now combine fig. 1 to 4 to explain the utility model discloses a prevent cylinder lamp injection moulding lamp shade of dew point and anti-dazzle, the cylinder lamp is including installing on radiator 10 prevent dew point and anti-dazzle lamp shade 20, and a LED lamp plate 30 is installed and is being should prevent between dew point and anti-dazzle lamp shade 20 and radiator 10.

The utility model discloses prevent dew point and anti-dazzle lamp shade 20 lamp shade as an organic whole injection moulding. The outer surface of the anti-dew point and anti-glare lampshade 20 is provided with an optical microstructure, and the optical microstructure is formed by an array of hexagonal pyramids 21 concavely arranged on the outer surface. The plurality of hexagonal pyramids 21 formed by the display of the dew points and the outer surface of the anti-glare lampshade can reduce UGR value by 4.5 numerical values at the position of 4H/8H, reduce stray light of the lampshade and achieve the purpose of reducing glare.

The utility model discloses prevent that dew point and anti-dazzle lamp shade 20's internal surface corresponds the mould surface and is atomizing treatment, can handle at mould surface sand blasting to the internal surface that makes this prevent dew point and anti-dazzle lamp shade 20 forms the surface through atomizing treatment. With the internal surface towards the LED lamp plate break up light, let the luminous chip on the LED lamp plate look more even from this dew point of preventing and anti-dazzle lampshade 20 outside, can not reveal the LED bright spot.

While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
