Abstract
The utility model discloses a fluorescent lamp shade which comprises a lamp shade fixing frame (1). A lamp shade (2) is mounted on the lamp shade fixing frame (1), and corrugated sections (3) are respectively arranged on two sides of the lamp shade (2). The lamp shade (2) is made of transparent materials, the section of the lamp shade (2) is semicircular, and an arc between the corrugated sections (3) is smooth. A central angle alpha corresponding to an arc section between the two corrugated sections (3) ranges from 110 degrees to 120 degrees. The corrugated sections (3) are serrated, and an included angle between each two adjacent serrated faces ranges from 50 degrees to 53 degrees.
Description
Technical field
The utility model relates to fluorescent lamp field, especially fluorescent lamp shade.
Background technology
Along with the maturation of LED technology, people bring into use the LED fluorescent lamp to replace traditional fluorescent lamp, so because its unidirectional illumination can only will form the dark space like this at its 120 degree scope intraoral illumination in the fluorescent lamp both sides, make lighting effect bad.
The utility model content
In order to solve deficiency of the prior art, provide fluorescent lamp the utility model of a kind of good illumination effect to design a kind of fluorescent lamp shade:
A kind of fluorescent lamp shade includes lampshade fixing frame, at lampshade fixing frame lampshade is installed, and the both sides on lampshade respectively are provided with bellows segment.
Described lampshade is that transparent material is made, and the cross section is semicircle, and the circular arc between the bellows segment is smooth.
Arc section between described two bellows segment the number of degrees of corresponding central angle alpha be 110 °～120 °.
Described bellows segment is zigzag, and the angle β between adjacent two serrated faces is 50 °～53 °.
Adopt the fluorescent lamp behind the above-mentioned fluorescent lamp shade can effectively reduce the dark space, increase illumination zone, make illuminating effect better.
The utility model content
As shown in figures 1 and 3, be provided with lampshade 2 at lampshade fixing frame 1, the material of lampshade 2 is transparent (or opalescence diffusion), lampshade fixing frame 1 and lampshade 2 form a cylinder T8 fluorescent lamp specification, wherein lampshade 2 cross sections are semicircle, lampshade 2 edge card are fixing in the draw-in groove of lampshade fixing frame 1, described lampshade 2 is provided with two sections bellows segment 3 with lampshade fixing frame 1 junction, the circular arc of lampshade is smooth between the bellows segment 3, the right central angle alpha of circular arc between two sections bellows segment 3 of lampshade 2 is 110 ° to 120 °, light direct projection in this angular range, and meeting produces diffuse reflection (the multiple refraction of light) after light runs into bellows segment 3, pass through like this after the diffuse reflection of bellows segment 3 so that the increase of light range of exposures, in order better to reach irreflexive effect, bellows segment 3 is set to zigzag as shown in Figure 2, and the angle beta of two adjacent surfaces is set to 50 ° to 53 °.
