Abstract

An LED lampshade comprises a lampshade body. The front end of the lampshade body is provided with a case with an arc-shaped surface, the surface of the case is provided with a plurality of small arc-shaped bulges playing the role of diverging a convex lens, and the plurality of bulges are arranged in parallel and uniformly distributed on the arc surface of the case; the rear part of the lampshade is provided with a heat dissipating hole, and the inner part thereof is provided with a base plate for fixing an LED; and a plurality of LED lamps are arranged on the base plate uniformly. The LED lampshade has the following benefits that the angle of the light emitted by the LED is changed by utilizing the angle and the distance of the LED and the lampshade, so that a point light emitting source of the LED is converted into a surface light emitting source of the LED so as to lead the light in the irradiating area is uniform, and compared with the like products, the LED lampshade is energy-saving and environment-friendly, and has the advantages of uniform light, low temperature and small light loss.

Description

The LED lampshade

Technical field

The utility model relates to a kind of LED lampshade.

Background technology

As everyone knows, LED is the direct projection light source that a point sends, and direction of illumination is single.Usually when using LED, all need to add a divergent lens (lampshade, lamp housing etc.) as scattering light source.According to the difference of field of employment, the degree of dispersing is also different.But it is faced with a problem is exactly that a LED lamp need be provided with a divergent lens, lamp housing, lampshade device, device structure complexity, cost height.

The utility model content

The purpose of this utility model provides and a kind of the LED electric light source is diverged to the LED lampshade of area source, solves existing device structure complexity, problem that cost is high.

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

The LED lampshade comprises cover body, is provided with the case of curved surfaces at the front end of cover body, is provided with the projection that playing of several little arcs dispersed the convex lens effect on the surface of case, and several projectioies adopt and are arranged side by side, and are distributed on the curved surfaces of case; Rear portion at lampshade is provided with louvre, and the inside of lampshade is equipped with the substrate of fixed L ED, evenly is furnished with several LED lamps on substrate.

The beneficial effects of the utility model are, utilize angle, the distance size of the long-pending face of LED and lampshade, the angle of the light that change LED sends, make its LED point illuminating source transfer the face illuminating source to, this some illuminating source of LED is converted into the face radiation source, make the light in its irradiated area even, energy-saving and environmental protection compared with similar products, light is even, temperature is low, the light loss consumption is little.

The specific embodiment

Shown in Fig. 1-3, Fig. 6-7, the LED lampshade comprises cover body 1, be provided with the case 2 of curved surfaces at the front end of cover body 1, be provided with playing of several little arcs on the surface of case 2 and disperse the projection 3 of convex lens effect, several projectioies 3 adopt and are arranged side by side, and are distributed on the curved surfaces of case 2;

Shown in Fig. 4-5, be provided with louvre 4 at the rear portion of lampshade, the inside of lampshade is equipped with the substrate 5 of fixed L ED, evenly is furnished with several LED lamps 6 on substrate 5.

The beneficial effects of the utility model are, utilize angle, the distance size of the long-pending face of LED and lampshade, the angle of the light that change LED sends, make its LED point illuminating source transfer the face illuminating source to, this some illuminating source of LED is converted into the face radiation source, make the light in its irradiated area even, compared with similar products energy-saving and environmental protection, light is even, temperature is low, light loss is little.
