Abstract
The utility model discloses a transparent cover for LED fluorescent lamp, which comprises a transparent plate and is characterized in that a plurality of concave-convex light distributing texture is arranged on the inner wall of the transparent plate; the cross section of the transparent plate is in the shape of a camber; and the light distributing texture of the cambered transparent plate is classified as stripes which are concave-convex distributed and parallel to the axis direction thereof. The shape of the transparent plate in the front of a lamp bead of an LED lamp is designed optimally, so that the transparent plate has the advantages of glare prevention, soft light, high light-emitting efficiency, and good uniformity and popularization value.
Description
Technical field
The utility model relates to technical field of lamps, particularly a kind of translucent construction of LED fluorescent lamp.
Background technology
At present, the LED fluorescent lamp adopts common diffuser on the market, be mainly used in waterproof, windproof, anticorrosion aspect, as Chinese patent application number is 00239435, and the applying date is on September 13rd, 2000, and denomination of invention is an arc light transmission piece fluorescent lamp, light source, reflection shield, housing are arranged, it is characterized in that: translucent arc light transmission piece is installed on the housing, and fluorescent tube is installed between reflection shield and the translucent arc light transmission piece, is hidden by translucent arc light transmission piece.The light of this patent structure is evenly soft, and is easy to clean, conveniently installs and removes fluorescent tube, but because without any the luminous intensity distribution design, so lack the anti-dazzle function, the light of process light transmission piece is inhomogeneous, light extraction efficiency is low.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, good evenness, light extraction efficiency height, and anti-dazzle, LED fluorescent lamp diffuser that light is soft.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of LED fluorescent lamp diffuser, comprise light-passing board, and it is characterized in that: the inwall of described light-passing board is provided with some concavo-convex alternate luminous intensity distribution textures.
As further specifying of such scheme, the cross section of described light-passing board is a camber, and the luminous intensity distribution texture of this camber light-passing board is the striped parallel with its axis direction of concavo-convex distribution.
Described some stripe are the inwall that undaform is distributed in light-passing board.
The central angle angle of described camber light-passing board correspondence is 90 °～180 °.
The inwall lug boss of described light-passing board is 1 with the width ratio of lower concave part: (1～5).
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the light-passing board with LED lamp pearl front, through the shape of design optimization light-passing board, at the inwall of light-passing board some concavo-convex alternate luminous intensity distribution stripeds is set, and light-passing board anti-dazzle, the light that draws is soft, good evenness, light extraction efficiency height.

Description of reference numerals: 1, light-passing board 2, luminous intensity distribution texture
The specific embodiment
As Fig. 1～shown in Figure 4, a kind of LED fluorescent lamp of the utility model diffuser comprises light-passing board 1, and the inwall of light-passing board 1 is provided with some concavo-convex alternate luminous intensity distribution textures 2, the cross section of light-passing board 1 is a camber, and the central angle angle of camber light-passing board correspondence is 90 °～180 °.The luminous intensity distribution texture 2 of this camber light-passing board is the striped parallel with its axis direction of concavo-convex distribution.Some stripe are the inwall that undaform is distributed in light-passing board 1, and its lug boss is 1 with the width ratio of lower concave part: (1～5).
The utility model is not limited to the foregoing description; described camber light-passing board can also adopt other form except adopting the striped luminous intensity distribution; those skilled in the art also can do numerous modifications and variations, under the spirit that does not break away from utility model, all in the claimed scope of the utility model.
