Abstract
The utility model discloses an LED lamp tube which comprises a power cord, a housing and a plurality of LEDs arranged in the housing. the LEDs are connected in series or in parallel on a printed circuit board and arranged in a vacuum glass tube; an LED lead wire is connected with the power cord through two wick columns with seal wires; the wick columns and the vacuum glass tube are sintered together at the end parts; and further the LEDs adopt luminous bodies with single color or with more than two colors. In the embodiment of the utility model, the housing adopts a PC tube made of transparent or semitransparent material; the LEDs in the utility model receive vacuum treatment, so that the LED burning point environment is changed, the LEDs work more stably, and oxidation resistance degree is higher; the lamp tube after vacuum treatment has greatly enhanced overall water resistance, moisture resistance, and anti-harsh environment capabilities; and the LED lamp tube has the advantages of reasonable structural design, safe and energy-saving use, and long service life.
Description
(1) technical field
The utility model relates to a kind of LED fluorescent tube, has waterproof and dampproof performance and can improve service life, belongs to the lighting apparatus technical field.
(2) background technology
Common fluorescent tube all is to make by electric current that filament is heated in the pipe, the argon molecules in the impact tube, heat is given birth in argon gas ionization, make mercury produce steam by heat effect and produce and send ultraviolet ray, ultraviolet ray excited down, tube wall fluorescent material can send white visible light.This kind fluorescent tube service life is short, filament is easily broken.
Development along with LED, people study and have made the LED fluorescent tube, its structure comprises power line, shell and several LED that are positioned at its inside, the LED fluorescent tube of this kind structure, work under non-vacuum environment, temperature uprises and is in shell, and air expansion can make its glue envelope place reveal, reduce waterproof and dampproof performance in it; A large amount of in addition air enter the meeting open circuit potential, damage LED, shorten its service life.
(3) summary of the invention
The technical problems to be solved in the utility model provides a kind of LED fluorescent tube, can effectively overcome the defective that prior art exists the sealing difference band, and not only has waterproof and dampproof performance and can improve service life.
In order to solve the problems of the technologies described above, the utility model is realized by following measure:
A kind of LED fluorescent tube, comprise power line, shell and several LED that are positioned at its inside, above-mentioned LED serial or parallel connection is on pcb board and be arranged in the glass tube with vacuum, and LED lead-in wire joins by two wick columns and the power line that has the sealing-in line, and described wick column and vacuum glass tube end sintering are together.
Further, described LED is made up of the solid color illuminator.
A nearlyer step ground, described LED is made up of the illuminator of two or more colors.
Among the utility model embodiment, described shell is the PC pipe that transparent or semitransparent material is made.
The beneficial effects of the utility model:
1. LED is carried out application of vacuum, made LED burning-point environment change, make the LED more stable work, anti-oxidant degree has improved greatly;
2. the fluorescent tube after the application of vacuum, integral waterproofing, humidity resistance and anti-adverse environment ability have strengthened greatly;
3. reasonable in design is safe in utilization, energy-conservation, long service life.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
1 power line among the figure, 2 shells, 3LED, 4 glass tube with vacuums, 5PCB plate, 6 wick columns.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, following explanation only is exemplary, does not limit protection domain of the present utility model.
A kind of LED fluorescent tube as shown in Figure 1, comprise power line 1, shell 2 and several LED3 that are positioned at its inside, above-mentioned LED3 serial or parallel connection is on pcb board 5 and be arranged in the glass tube with vacuum 4, and the LED3 lead-in wire joins with power line 1 by two wick columns 6 that have the sealing-in line, and described wick column 6 and glass tube with vacuum 4 end sintering are together.
The manufacturing course of work is as follows: with after pcb board 5 is connected, the wick column 6 that will contain 2-10 root sealing-in line carries out burn-back with glass tube with vacuum 4, allows glass tube with vacuum 4 be evacuated to vacuum state then, gets final product in the shell 2 of at last it being packed into LED3.
Described LED can be made up of the solid color illuminator during manufacturing, also can be made up of the illuminator of two or more colors.The PC pipe that described shell 3 is made for transparent or semitransparent material.
Claims (4)
1. LED fluorescent tube, comprise power line (1), shell (2) and be positioned at several LED (3) of its inside, it is characterized in that: above-mentioned LED (3) serial or parallel connection is gone up and is arranged in the glass tube with vacuum (4) in pcb board (5), and LED (3) lead-in wire joins with power line (1) by two wick columns (6) that have the sealing-in line, and described wick column (6) and glass tube with vacuum (4) end sintering are together.
2. according to the described LED fluorescent tube of claim 1, it is characterized in that: described LED is made up of the solid color illuminator.
