Abstract
The invention discloses an LED (light emitting diode) fluorescent tube comprising a light guide pillar and an LED (light emitting diode). The light guide pillar is made of materials with first refractive index. A cavity is formed on the inner portion of the light guide pillar. Light guide media with second refractive index used for guiding light are filled in the cavity. The first refractive index is greater than the second refractive index. The LED is at least arranged at one end of the light guide pillar. The using number of the LED is reduced, and a conventional arrangement with a plurality of low-power lamp strips is transformed into a novel arrangement with two or even one high-power LED, so that cost is reduced, and products are convenient to assemble.
Description
Technical field
The present invention relates to a kind of fluorescent tube, especially a kind of LED fluorescent tube based on leaded light cylindricality formula belongs to the LED lighting field.
Background technology
Illuminating lamp tube in the past is the fluorescent tube that the phosphor material powder that utilizes the ultraviolet ray excited glass tube inwall of low-pressure mercury vapour discharge generation to scribble is converted into visible light, or the low-power LED lamp bar is put into the LED fluorescent tube that annular acrylic cover forms.
Low-power LED fluorescent tube in the past has following shortcoming:
1) LED number is many, needs dozens or even hundreds of.I haven't seen you for ages causes the lighting tube brightness inequality for number, sees through lampshade visible fluorescence shaped laser spot.
2) increasing of LED number causes uniformity photochromic between the led light source to be difficult to control.
3) LED fluorescent tube, last irradiation account for about the logical 0-10% of total light, and the light of 100-90% shines downwards, belongs to direct illumination, and type of lighting is single.For the place that needs semidirect illumination, semiindirect lighting, need increase LED lamp bar or LED number to realize comprehensive illumination.
Summary of the invention
Problem at prior art exists the object of the present invention is to provide a kind of LED of less number and LED fluorescent tube that photochromic uniformity can be controlled preferably of using.
A kind of LED fluorescent tube of the present invention comprises:
The leaded light post forms by having first refractive index materials, and described leaded light post inside is formed with cavity, is filled with the light-conductive media that is used for leaded light with second refractive index in described cavity, and described first refractive index is greater than second refractive index;
LED is arranged at least one end of described leaded light post.
Preferably, described leaded light post has optical grade glass or plastics to form.
Preferably, described light-conductive media is gas, water, oil or leaded light solid.
Preferably, described light-conductive media also is mixed with phosphor material powder.
Preferably, described LED is single great power LED or COB product.
Preferably, described cavity cross section is spliced to form up and down by the circle of two different-diameters or is spliced to form by the conic section of different curvature.
Preferably, described leaded light outer surface of column is printed with and makes the light that is coupled in the described leaded light post evenly diffuse to the diffusion site on whole described leaded light post surface.
The present invention compares with LED fluorescent tube in the past, has following advantage:
1) reduces LED and use a number, change two even a great power LED into by many traditional small light strips, save cost, be convenient to the assembling of product.
2) great power LED of less number of use, photochromic uniformity can be controlled preferably.
3) the leaded light post be 360 ° luminous, by handle in the diffusion site of its outer surface, the different structure form of plating high-reflecting film and inner surface, can satisfy the requirement of type of lighting such as direct illumination, indirect lighting, semidirect illumination.
4) the inner blanketing gas of hollow type leaded light post, liquid or solid etc. form different illuminating colors, and are economical and beautiful.

The specific embodiment
As shown in Figure 1, 2, LED fluorescent tube of the present invention comprises: leaded light post 64 and LED62, leaded light post 64 forms by having first refractive index materials, leaded light post 64 inside are formed with cavity 68, in cavity 68, be filled with the light-conductive media that is used for leaded light with second refractive index, in embodiments of the present invention, first refractive index is greater than second refractive index, so that the light that will transmit in light-conductive media is derived by leaded light post 64.LED62 is great power LED, generally can adopt the above LED of 4W, can obtain lighting effect preferably, and LED62 is arranged at least one end of leaded light post 64.That is to say to get final product one-sided setting, but also bilateral setting.
In embodiments of the present invention, have that the leaded light post 64 of first refractive index is optional to be made with optical grade glass or plastics, light-conductive media can select to have gas, water, oil or the leaded light solid of second refractive index in addition.
In addition, light-conductive media also is mixed with phosphor material powder, can adopt blue-ray LED to excite the fluorescent material in the leaded light post 64 and form white light like this.
In embodiments of the present invention, LED is single great power LED or COB product.
In addition, as shown in Figure 3, it is that the circle of different curvature is spliced to form or the conic section splicing construction of different curvature that cavity 68 forms the cross section, thus can according to on the ratio of penetrating light and penetrating light down regulate light in spatial distributions, and reach the uniform effect of fluorescent tube upper and lower surface illumination.
In addition, as shown in Figure 2, leaded light post 64 outer surfaces are printed with and make the light that is coupled in the leaded light post 64 evenly diffuse to the diffusion site 70 on whole leaded light post 64 surfaces.Like this, leaded light post 64 is can 360 ° luminous, by the diffusion site at its outer surface handle, the different structure form of plating high-reflecting film and inner surface, can satisfy the requirement of type of lighting such as direct illumination, indirect lighting, semidirect illumination.
Application example 1:
As shown in Figure 4, the high-power COB of 2 6W cooperates the leaded light post, is applied to LED T5 pipe.
Every 6W COB is placed leaded light post two ends, and hollow type leaded light post inside is air, and the leaded light outer surface of column adopts printing net-point, and the light that COB is sent is coupled into the leaded light post uniformly.Plating high-reflecting film in leaded light outer surface of column top is so that light beam is from the outgoing of leaded light post lower surface.
Application example 2:
As shown in Figure 5,1 10W great power LED is coupled to an end of leaded light post, leaded light post inner section is circular, and middle vacancy is air, and the light of LED forms exquisite appearance, the uniform 10W LED of briliancy bulb lamp through the refraction of leaded light post.
