Abstract
The utility model discloses an LED (Light Emitting Diode) lamp tube comprising end covers, a metal housing and an LED lamp panel, wherein the end covers are distributed on the two sides of the LED lamp tube, and wherein the end cover on one side is connected to the LED lamp panel, while the end cover on the other side is connected to the metal housing. The LED lamp tube provided in the utility model is simple in structure, low in cost and good in safety property, thereby ensuring the body safety of users.
Description
Technical field
The utility model relates to lighting field, particularly a kind of LED fluorescent tube.
Background technology
The LED fluorescent tube also is commonly called as light pipe, fluorescent tube, and its light source adopts LED as illuminator.Present LED fluorescent tube structurally mainly contains following two kinds of forms:
Led driver is built in fluorescent tube, and AC power input in two ends still, because the metal shell of fluorescent tube and the high temperature in the fluorescent tube can impact life-span, the safety of driver, can constitute life to the user and threaten when installing and use;
Led driver is placed in the lamp bracket, and can there be safety problem in direct current input in two ends equally, and the G5/G13 lamp holder that adopts causes puzzlement can for the user when direct current is imported when mounted.
Summary of the invention
The utility model embodiment technical problem to be solved is, a kind of LED fluorescent tube is provided, and said LED lamp tube structure is simple, with low cost, security performance is good, guarantee user's personal safety.
For reaching above-mentioned technique effect; The utility model embodiment provides a kind of LED fluorescent tube; Comprise: end cap, metal shell and LED lamp plate, said end cap is distributed in the both sides of said LED fluorescent tube, wherein; The end cap of one side links to each other with said LED lamp plate, and the end cap of opposite side links to each other with said metal shell.
As the improvement of such scheme, a side end cap that links to each other with said LED lamp plate is provided with dc supply input.
As the improvement of such scheme, said dc supply input comprises positive and negative plug;
The both positive and negative polarity of said positive and negative plug corresponding said LED lamp plate of difference and socket.
As the improvement of such scheme, the opposite side end cap that links to each other with said metal shell is provided with ground pin;
The earth terminal of said ground pin respective socket.
As the improvement of such scheme, said LED fluorescent tube also comprises diffuser.
Enforcement the utlity model has following beneficial effect:
Compared with prior art, the end cap of the utility model one side links to each other with said LED lamp plate, and the end cap of opposite side links to each other with said metal shell.A side end cap that links to each other with said LED lamp plate is provided with dc supply input, and the opposite side end cap that links to each other with said metal shell is provided with ground pin.Therefore, adopt single-ended direct current input, earth terminal is provided, higher security protection can be provided, ensure user's personal safety.
And, because the metal shell of fluorescent tube and the high temperature in the fluorescent tube can impact life-span, the safety of driver.Therefore, the utility model is external with led driver, avoids led driver to influence lamp tube service life, has effectively prolonged the service life of fluorescent tube.
In addition, the utility model LED lamp tube structure is simple, with low cost, manufacture craft is simple.
Description of drawings
Fig. 1 is the exploded perspective view of a kind of LED fluorescent tube of the utility model;
Fig. 2 is the assembling sketch map of a kind of LED fluorescent tube of the utility model.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done to describe in detail further below.
In conjunction with Fig. 1 and Fig. 2, the utility model embodiment a kind of LED fluorescent tube is provided; Comprise: end cap 1, metal shell 2 and LED lamp plate 3; Said end cap 1 is distributed in the both sides of said LED fluorescent tube; Wherein, the end cap 11 of a side links to each other with said LED lamp plate, and the end cap 12 of opposite side links to each other with said metal shell.
Compare with common fluorescent tube, the LED light pipe adopts light emitting diode as light source, and light efficiency is higher, more energy-conservation, longer service life, and more environmental protection.The economize on electricity of LED fluorescent tube is up to more than 70%, and the life-span is more than 10 times of common fluorescent tube, almost is non-maintaining, does not have the problem that will often change fluorescent tube, ballast, starter.In addition, light is soft, helps people's sight protectio and healthy.
A side end cap 11 that links to each other with said LED lamp plate 3 is provided with dc supply input 4.
Said dc supply input 4 comprises positive and negative plug;
The both positive and negative polarity of said positive and negative plug corresponding said LED lamp plate 3 of difference and socket.
The opposite side end cap 12 that links to each other with said metal shell is provided with ground pin 5;
The earth terminal of said ground pin 5 respective socket.
Adopt single-ended direct current input, and earth terminal is provided, higher security protection can be provided, ensure user's personal safety, avoid the influence of thunder and lightning or other factors.
Said LED fluorescent tube also comprises diffuser 6.
Said diffuser 6 helps seeing through of light and disperses, and can improve the brightness of illumination of LED fluorescent tube.
In sum, implement the utlity model has following beneficial effect:
Compared with prior art, the end cap of the utility model one side links to each other with said LED lamp plate, and the end cap of opposite side links to each other with said metal shell.A side end cap that links to each other with said LED lamp plate is provided with dc supply input, and the opposite side end cap that links to each other with said metal shell is provided with ground pin.Adopt single-ended direct current input, earth terminal is provided, higher security protection can be provided, ensure user's personal safety.
And, because the metal shell of fluorescent tube and the high temperature in the fluorescent tube can impact life-span, the safety of driver.Therefore, the utility model is external with led driver, avoids led driver to influence lamp tube service life, has effectively prolonged the service life of fluorescent tube.
In addition, the utility model LED lamp tube structure is simple, with low cost, manufacture craft is simple.
The above disclosed preferred embodiment that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
