Abstract

The utility model relates to a lampshade of an LED desk lamp. The lampshade can effectively and uniformly diffuse the point-like light sources emitted from a plurality of LED lamps to enable the lights to be more uniform and softer, and has the properties of low light loss, long range and energy saving. The technical schemes of the utility model are that the lampshade includes an LED lamp substrate and a cover body, a notch is arranged on the cover body, the LED lamp substrate is arranged in the notch, transverse arc-shaped grooves are uniformly distributed on the inner wall of the cover body, longitudinal arc-shaped protrusions are arranged at the bottom of the cover body, and a reflective mirror surface is formed by inclining the two edges of the cover body at an angle of 45 degrees. The lampshade provided is simple in structure, reasonable in design, and convenient in use, furthermore, the lampshade can effectively adjust the dazzling point-like light source of the LED desk lamp into soft and uniform light which is low in light loss, and the lampshade eliminates the problems of multiple light sources and multiple bright spots to protect eyes, in addition, the lampshade provided enhances the spotlight effect and brightness at some degree, thereby saving more energy.

Description

A kind of LED desk lamp lampshade

One, technical field

The utility model relates to lampshade, particularly is applied to a kind of LED desk lamp lampshade of LED desk lamp.

Two, background technology

In recent years, because the LED lamp is compared with fluorescent lamp with incandescent lamp, has energy saving, long service life, be difficult for broken, do not glimmer, advantages such as toggle speed is fast, environmentally safe, the support energetically and the development of the country that obtains, now be widely used in industry and commercial lighting, for example: high-brightness LED street lamp, the electronic car light of LED, LED ornament lamp or the like.Yet the LED lighting device is being applied to domestic lighting, also deposit following defective during daily lighting: for example forms by a plurality of LED lamps in the LED desk lamp, and LED lamp and traditional illuminator difference are, the light source that it produced has the feature that concentrates on the specific region angle, be scattered point source of light, in case when a plurality of LED lamp is set on same lighting, just have multiple light source, the problem of many bright spots takes place, and multiple light source, many bright spots are easy to cause irradiation inhomogeneous, shone thing has the situation of multi shadow, allow the user dazzling easily, and the point source of light that each LED forms is all very dazzling again, severe especially to eye irritation, the long-term use, eye health must be affected.The most lampshades that adopt of present LED desk lamp for handle through cloudy surface the engineering plastics lampshade, to overcoming above defective DeGrain, and the light loss consumption is high, range descends.

Three, summary of the invention

At above-mentioned situation, for overcoming deficiency of the prior art, the purpose of the utility model just provides a kind of LED desk lamp lampshade, can effectively solve and the point source of light that a plurality of LED lamps are sent evenly can be spread, make light more even, soft and light loss is low, far firing range, problem of energy saving more.

The technical solution of the utility model is as follows: include LED lamp substrate and cover body, draw-in groove is arranged on the cover body, the LED lamp substrate is housed in the draw-in groove, be evenly distributed with horizontal arc groove on the cover body inwall, there is vertical circular arc projection the cover body bottom surface, and inclination miter angle in cover body both sides has reflective mirror.

The utility model is simple in structure, reasonable in design, easy to use; can be effectively the dazzling point source of light of LED desk lamp be adjusted to soft, uniform light; light loss is low; eliminated the problem of multiple light source, many bright spots; the protection eyes; and strengthened spotlight effect and brightness to a certain extent, more energy-conservation.

Four, description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

As shown in drawings, the utility model includes LED lamp substrate and cover body, and draw-in groove 7 is arranged on the cover body 3, LED lamp substrate 2 is housed in the draw-in groove, be evenly distributed with horizontal arc groove 4 on cover body 3 inwalls, there is vertical circular arc projection 5 cover body 3 bottom surfaces, and cover body 3 both sides inclination miter angles have reflective mirror 6.

The outside of said cover body 3 is transparent isosceles trapezoid, and inside is semicircle hollow cavity.

Said horizontal arc groove 4 and vertical circular arc projection 5 mutual arranged verticals.

Operating position of the present utility model is, during use, the LED lamp is contained in the centre of LED substrate 2, vertically equidistant a plurality of arrangements; Parallel to each other with the axis of cover body 3; Cover body 3 is a transparent material; profile is an isosceles trapezoidal structure; inside is the semicircle hollow structure; cover body 3 inwalls are evenly distributed with horizontal arc groove 4; utilize optical principle; laterally arc groove 4 is horizontal linear light beam with the point source of light elongation that the LED lamp sends; the point source of light that vertical circular arc projection 5 of cover body 3 bottom surfaces is sent the LED lamp again elongates the vertical linear light beam; two form equally distributed soft light source in length and breadth to the vertical weave in of light beam; eliminated the problem of the dazzling light of LED lamp and multiple light source, many bright spots, protection user's eyes.Reflective mirror 6 by lampshade body both sides inclination miter angle reflective strengthened the spotlight effect and the brightness of LED desk lamp, and the LED lamp can be used littler power, and is more energy-conservation.The draw-in groove 7 of cover body top directly is stuck in the effect of playing fixed L ED lampshade on the LED substrate 2.

By above-mentioned situation as can be seen, the utlity model has following beneficial effect:

1, simple in structure, reasonable in design, easy to use.

2, effective dazzling point source of light with the LED desk lamp is adjusted to soft, uniform light, and light loss is low, has eliminated the problem of multiple light source, many bright spots, the protection eyes.

3, strengthened spotlight effect and brightness to a certain extent, more energy-conservation.
