Description

LED lamp and its lampshade

The present invention relates to LED lighting technology, and more particularly to an LED lamp and a lampshade thereof.

The existing LED lamp is composed of an LED lamp module mounted on an aluminum substrate, a power module, a PC (Polycarbonate in English, polycarbonate in Chinese), and a plug. The lampshade is made of transparent or translucent plastic material, and the surfaces on both sides are smooth, which has the following defects: First, the prior art PC lampshade is smooth on both sides, and cannot cause secondary optical effects on light, and the light passes through the PC. When the lampshade forms a direct light source, the light is not soft, which not only irritates the eyes, but also easily causes fatigue; secondly, because the LED lamp bead group illuminates more light in the middle of the PC lampshade, and the prior art PC Both sides of the lampshade are smooth, so they cannot produce secondary optics to the light. Therefore, the middle of the PC lampshade is brighter, and the sides are darker, resulting in uneven brightness.

In view of this, the purpose of the present invention is to provide an LED lamp and a lampshade thereof, which can soften the light and maintain uniform illumination in the lampshade.

In order to solve the above technical problem, the technical solution provided by the present invention is: a lampshade comprising a transparent or translucent semi-arc cylindrical lampshade body, and a light reflecting structure is disposed on an inner wall surface of the lampshade body.

In a preferred embodiment, the light reflecting structure is disposed on the inner wall of the lampshade body. A plurality of protrusions on the surface.

In a preferred embodiment, the plurality of protrusions are of equal size.

In a preferred embodiment, the plurality of protrusions are spaced apart by a certain distance.

In a preferred embodiment, the plurality of protrusions are arcuate protrusions.

In a preferred embodiment, the lampshade body has an opening extending laterally inwardly from the two sides of the opening.

In a preferred embodiment, the lampshade body is a PC (polycarbonate) lampshade body.

On this basis, the present invention provides an LED lamp comprising a LED lamp bead set and a power supply module connected in series and parallel, and a lamp cover provided as described above.

In a preferred embodiment, the cross-sectional area of the aluminum cover of the LED lamp of the LED lamp accounts for one-third of the cross-sectional area of the lamp, and the cross-sectional area of the lamp cover accounts for two-thirds of the cross-sectional area of the lamp.

In a preferred embodiment, the LED bead set is mounted on a substrate.

Compared with the prior art, the inner wall surface of the present lampshade body is provided with a light reflecting structure to soften the light and maintain uniform illumination within the lampshade. Specifically, the present invention includes but is not limited to the following advantages: (1) The creation of the PC lampshade has the function of secondary optics. The light will form a non-direct light source through the creation of the PC lampshade. The light is soft, it will not irritate the eyes, and it will not easily cause fatigue. (2) The brightness of the PC lampshade is uniform to improve The middle of the PC lampshade is brighter, and the sides are darker.

In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

Referring also to Figures 1 and 2, there is shown a structure of a preferred embodiment of the present lampshade, the lampshade comprising a semi-arc cylindrical lampshade body 1 which is transparent or translucent (preferably PC, Chinese polycarbonate), A cross-shaped wall extends inwardly from both sides of the opening. The lampshade body 1 has a length L1 of 1172 mm; an outer diameter D of 26.8 mm; a thickness Dr of 0.8 mm; an opening height H1 of 21 mm; a width L2 of 16.8 mm; and an opening thickness H2 of 0.6 mm. The inner wall surface of the lampshade body 1 is provided with a light reflecting structure. Specifically, a plurality of arc-shaped protrusions 2 of the same size and a fixed pitch are disposed on the inner wall surface of the lampshade body 1, thereby forming a light reflecting structure, and finally generating Secondary optics.

Please refer to Figure 3 for the optical path principle of this creation. When the light of the LED lamp 3 is irradiated on the arc-shaped protrusion 2, the arc-shaped protrusion 2 reflects a certain light, so that the PC lamp body 1 has the function of secondary optics, specifically: on the one hand, the light passes through the PC lamp cover. When the body 1 is formed, a non-direct light source is formed, the light is soft, does not irritate the eyes, and is not easy to cause fatigue; on the other hand, the light passes through the secondary optics to make the light uniformly pass through the PC lamp cover body 1, thus The brightness of the PC lampshade is uniform, and the middle of the PC lampshade is brighter, while the sides are darker.

On the basis of this, the LED lamp of the present invention comprises an LED lamp bead group connected in series and parallel, a power module and the above lampshade, wherein: the LED lamp bead group is mounted on a substrate; the cross-sectional area of the aluminum lamp cover of the LED lamp is occupied. One-third of the cross-sectional area of the lamp, the cross-section of the lampshade The cross-sectional area accounts for two-thirds of the cross-sectional area of the tube, so that the angle of illumination of the tube is 270 degrees.

The creation structure is simple, the production is easy, the cost is low, and the market prospect is promising. At present, there is no similar product solution in the market.

The above is only a preferred embodiment of the present invention. It should be noted that the above preferred embodiments should not be construed as limiting the present invention. The scope of protection of the present invention should be based on the scope of the patent application. It will be apparent to those skilled in the art that a number of improvements and modifications may be made without departing from the spirit and scope of the present invention, and such improvements and modifications should also be considered as protection of the present invention.
