Problems solved by technology

However, the design is unreasonable, especially the light transmittance of the small facets of the lampshade is poor, and the total reflection is serious, resulting in poor light output and reduced brightness.

Embodiment Construction

[0019] refer to figure 1 with figure 2 , Daylight-type LED tube lampshade, lampshade 1 is formed by transparent material, and the cross-section is an arc-shaped structure. The arc-shaped structure means that the radius of the central area is large, and the radius of the two sides gradually becomes smaller, forming a semi-circle or semi-ellipse. The arc structure, of course, does not exclude the semi-circular arc or semi-elliptical arc structure; the two sides of the lampshade 1 are symmetrically formed with inward buckle feet 2, the outer surface of the lampshade 1 is smooth, and the inner surface is formed with densely arranged thin stripes 3, fine stripes 3 The section is arc concave structure, forming a concave lens light diffusion mirror surface; the arc height of the thin stripes 3 is less than 0.3 mm, and the radius is less than 0.6 mm; more specifically, the arc surface of the thin stripes 3 on the inner surface of the lampshade 1 is double Composed of circular arcs, ...

Abstract

The invention relates to a sunlight-type LED lamp tube lamp cover which is formed by transparent materials. The section is of an arc structure. Buckling feet for locating are symmetrically formed at the two edges. The lamp cover is characterized in that the outer surface of the lamp cover is smooth, intensive-arrayed thin lines are formed on the inner surface of the lamp cover, the sections of the thin lines are of an arc down-concave structure, concave lens light dispersing mirror surfaces are formed, the thin line arc height is smaller than 0.3mm, and the radius is smaller than 0.6mm. The intensive-arrayed down-concave arc thin lines are formed on the inner surface of the lamp cover, the concave lens light dispersing mirror surfaces are formed, especially the asymmetric down-concave thin lines achieve light dispersing, light-emitting angles are dispersed, lamp cover surface light emitting is even, the shortcoming of LED light source dazzling is overcome, the lamp cover is of a semi-arc-similar or a semi-elliptic-arc-similar structure, and accordingly light intensity on the two sides is improved.

Description

Technical field: [0001] The invention belongs to the field of lighting, and in particular relates to an improvement of a sunlight-type LED lamp shade. Background technique: [0002] As we all know, the transparent lampshade has the highest light efficiency, but it can clearly see the light source, which is obviously insufficient for high-brightness LED lamp beads, which is easy to cause visual damage and serious glare. For this reason, most LED light sources use frosted lampshades to achieve atomization and diffusion, so as to improve the light angle and adjust the uniformity of light output. However, the design is unreasonable, especially the small facets of the lampshade have poor light transmittance and serious total reflection, resulting in poor output light efficiency and reduced brightness. How to design the LED lampshade, which not only meets the needs of light diffusion, but also reduces the structure of total reflection, becomes the object of research of the presen...
