Abstract
The utility model provides an LED fluorescent tube and a light penetrating cover. The LED fluorescent tube comprises an LED, a circuit board and a light penetrating cover, wherein the LED is mounted on the circuit board; the light penetrating cover covers one side of the circuit board where the LED is mounted; and protruded strips are formed on one side where the light penetrating cover is opposite to the LED. The protruded strips are used for refracting light beams of the LED to achieve more uniform light emission of the LED fluorescent tube.
Description
[technical field]
The utility model relates to lighting technical field, more particularly, relates to a kind of LED fluorescent tube and diffuser thereof.
[background technology]
Light emitting diode (Light Emitting Diode is called for short " LED ") is because advantages such as its life-span length, energy-saving and environmental protection now are applied to lighting field more and more widely.The LED fluorescent tube is luminous by its inner LED lamp, and the light transmission diffuser that sends is realized illumination.At present, the diffuser of LED fluorescent tube is made by transparent or smooth milky PC material mostly.With the diffuser that transparent PC material is made, then can't avoid single LED lamp pearl to bring visually dizzy, dazzling sensation to the people; And the diffuser that adopts smooth milky PC material to make, the light efficiency that can make LED is with a toll of 12%～20% more than, and because trickle distortion and the brightness of the different lighting angles of LED lamp of PC material after assembling is different, can make the light-emitting area of LED fluorescent tube seem inhomogeneous, thereby influence result of use.
[utility model content]
Based on this, be necessary to provide a kind of LED of making fluorescent tube luminous more uniform diffuser.
In addition, also be necessary to provide a kind of energy luminous more uniform LED fluorescent tube.
Described LED fluorescent tube comprises LED, circuit board and diffuser, and described LED is installed on the described circuit board, and described diffuser covers on the one side that circuit board is installed LED, and the side of the described relatively LED of described diffuser is provided with the striped of projection.
Preferably, described diffuser one side opening, its cross section archwise.
Preferably, the cross section of the striped of described projection becomes semicircle.
Preferably, contain 2%～15% makrolon material in the described diffuser.
Described diffuser is dressed up the LED fluorescent tube with the circuit board group that LED is housed, and the side of the described relatively LED of described diffuser is provided with the striped of projection.
Preferably, described diffuser one side opening, its cross section archwise.
Preferably, the cross section of the striped of described projection becomes semicircle.
Preferably, contain 2%～15% makrolon material in the described diffuser.
Above-mentioned LED fluorescent tube and diffuser, because the inboard of diffuser is provided with the striped of projection, the light that makes the LED lamp send carries out the several refraction in diffuser, can make the bright dipping of light-emitting area more even like this.
[description of drawings]
Fig. 1 shows the sectional view of a diffuser among the embodiment;
Fig. 2 shows the sectional view of a LED fluorescent tube among the embodiment.
[specific embodiment]
As depicted in figs. 1 and 2, the LED fluorescent tube comprises diffuser 1, circuit board 3 and LED 4.LED 4 is installed on the circuit board 3.Diffuser 1 one side openings, its cross section archwise, opening part cover on the one side that circuit board 3 is installed LED 4.Be provided with the striped 2 of projection in the side of the relative LED 4 of diffuser 1, the cross section of this striped 2 can be shapes such as semicircle.The striped 2 of projection will repeatedly reflect the light that LED 4 sends, and like this, the light that LED fluorescent tube light-emitting area is sent is more even.In one embodiment, contain 2%～15% Merlon (PC) material in the diffuser 1, it can be milky, can require to set according to different printing opacities.In addition, diffuser 1 also can be glass or acrylic material.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (6)
1. a LED fluorescent tube comprises LED, circuit board and diffuser, and described LED is installed on the described circuit board, and described diffuser covers on the one side that circuit board is installed LED, it is characterized in that, the side of the described relatively LED of described diffuser is provided with the striped of projection.
2. LED fluorescent tube according to claim 1 is characterized in that, described diffuser one side opening, its cross section archwise.
