Abstract

The utility model discloses a kind of LED lamp tube.Fluorescent tube mainly comprises glass tube, LED light source plate, lamp holder, colour reflective paper and diffusion barrier.In this utility model, after the reflecting paper reflection of the some light that LED sends through having special spectrum reflectivity, colour temperature changes a lot, and mix with unreflected light, its colour temperature obtains decline to a certain extent compared with the colour temperature of LED light source self.Meanwhile, by adjusting the area coverage of reflecting paper and being overlying on the diffusion barrier on glass tube surface, control the lighting angle of LED lamp tube, make the bright dipping of fluorescent tube comparatively even.

Description

A kind of LED fluorescent lamp tube

Technical field

The utility model belongs to technical field of LED illumination, especially a kind of LED fluorescent lamp tube.

Background technology

In recent years, along with the development of LED light source and chip technology, it relies on specular removal, long-life, low-power consumption, abundant chromatic characteristic, is convenient to carry out the many advantages such as Based Intelligent Control and environmental friendliness neatly, along with the cost reduced gradually, occupies general illumination market gradually.

Traditional fluorescent lamp generally adopts filament heating, excites internal gas Discharge illuminating, and this fluorescent lamp power consumption is large, service life is short, and ambient influnence is large, not only wastes energy in a large number, more causes white elephant to natural environment.

Along with the LED having environmental protection and energy saving requirement concurrently is applied to fluorescent tube, LED lamp tube solves the shortcoming of above-mentioned fluorescent lamp well.LED lamp tube adopts LED as light source, become the lighting be most widely used gradually, become the most ideal product that the current stage replaces common fluorescent lamp, be widely used in the occasions such as office space, garage, supermarket, public place, bring many convenience to the life of people.

The technical problem that existing LED lamp tube exists is as follows: the transparent cover body of (1) fluorescent tube easily because broken splashing, and causes unexpected damage; (2) owing to there is certain spacing between LED particle, there is the situation of light and shade inequality in fluorescent tube, and surperficial light intensity is uneven.In order to overcome the deficiencies in the prior art, adapt to the needs of reality, how designing a kind of efficient, that uniformity is good, explosion-proof LED lamp tube becomes the direction that those skilled in the art make great efforts.

CN201210313875.8 discloses a kind of explosion proof type LED fluorescent tube, with rupture pressure disc on its fluorescent tube lid inwall, ensure that lid glass blast can not occur because breaking and splashes, ensure that use safety.

CN201320656989.2 discloses a kind of LED lamp tube, and its glass tube outer wall is coated with for increasing rising angle, improve dazzle and protect the diffusion barrier of described glass tube, effectively prevent glass tube broken time cause unexpected injury to human body.

For the inside rupture pressure disc mentioned in above-mentioned patent, its manufacture craft is comparatively complicated, can only be processed as monochromatic film, effectively cannot solve the contradiction between the uneven and light efficiency of surface of the light tube light intensity.And for the diffusion barrier of outer wall, can be processed as double-colored, with the problem solving light efficiency and LED lamp tube uniformity.But the material of double-colored diffusion barrier is more crisp, easily ftractures, and not easily produces, and to production technology limited angle system, when fluorescent tube rotates, uniformity is very poor.

Summary of the invention

The purpose of this utility model is to provide a kind of LED lamp tube, is intended to solve the problem of fluorescent tube light and shade inequality, low colour temperature fluorescent tube uniformity difference in prior art.By adopting colored reflecting paper, control the spectrum of the LED light source of high color temperature, that reduces fluorescent tube goes out light color temperature, replaces the low colour temperature LED light source that uniformity is poor.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

LED lamp tube structure described in the utility model comprises glass tube, LED light source plate, lamp holder, colour reflective paper, diffusion barrier.Wherein said glass tube two ends are provided with lamp holder, and LED light source plate is fixed on glass tube, and the outside of glass tube is coated with one deck diffusion barrier, and colour reflective paper is positioned at fluorescent tube shady face, is placed between diffusion barrier and glass tube.

The diffusion barrier that the high uniformity of surface of the light tube is covered with by glass tube outside coordinates inner colour reflective paper to realize.The blocking of diffusion barrier reflecting paper that wherein glass tube outside is covered with makes the Luminance Distribution of surface of the light tube more even.

The utility model adopts colored reflecting paper, is placed in glass tube shady face.The light that high color temperature LED sends is after reflecting paper reflection, and its colour temperature declines, and mix with the light without reflecting paper, finally exported light, its colour temperature obtains decline to a certain extent compared with the colour temperature of LED light source self.

Reflecting paper of the present utility model is placed in glass tube shady face, by the area coverage of accommodation reflex paper, can control the size of the exiting surface of LED lamp tube, thus controls the lighting angle of LED lamp tube.

Fig. 1 is sectional view of the present utility model.

Fig. 2 is appearance schematic diagram of the present utility model.

Reference numeral is as follows:

Glass tube (1), LED light source plate (2), lamp holder (3), colour reflective paper (4), diffusion barrier (5).

Detailed description of the invention

The utility model LED lamp tube structure as shown in Figure 1, comprises glass tube (1), LED light source plate (2), lamp holder (3), colour reflective paper (4), diffusion barrier (5).Wherein said glass tube (1) two ends are provided with lamp holder (3), it is inner that LED light source plate (2) is fixed on glass tube (1), the outside of glass tube (1) is coated with one deck diffusion barrier (5), and colour reflective paper (4) is placed in fluorescent tube shady face, is positioned between glass tube (1) and diffusion barrier (5).

Adopt above-mentioned LED fluorescent lamp tube, there is following features:

1) closing in is left at the two ends of glass tube (1), convenient at two ends processing aluminium cap, as lamp holder;

2) outer wall of glass tube (1) is coated, and one deck includes the diffusion barrier (5) of diffusible substance, increases the beam angle of fluorescent tube, improves light-emitting uniformity;

3) colour reflective paper (4) is placed in the shady face of glass tube (1), improve the light efficiency of LED lamp tube on the one hand, on the other hand, there is the LED light line of high color temperature after reflecting paper reflection, colour temperature reduces, can be used to replace the fluorescent tube adopting low colour temperature LED, its colour consistency performance is improved.

By regulating the area coverage of colour reflective paper (4), can control the size of the exiting surface of LED lamp tube, thus control the lighting angle of LED lamp tube.
