Abstract
The utility model discloses an LED annular light tube. The LED annular light tube comprises a lamp cap (1) made of insulating material; wherein, the lamp cap (1) is provided with metal pins (2), and connected with a annular transparent tube (3); a circuit board (4) is arranged in the transparent tube (3); and a plurality of LEDs (5) are arranged in the circuit board (4), and are electrically connected with the metal pins (2) through wires arranged on the circuit board (4). The utility model has a simple structure, which can be directly conveniently assembled on the prior light fixtures with the annular light tube, has the advantages of LED illumination, that are high practicability and a promotion value and can be widely used in households, public places and the like.
Description
Technical field
The utility model belongs to the technical field of lighting, specifically is meant a kind of LED annular lamp tube that is used to throw light on.
Background technology
Common in the market annular lamp tube generally is to be made as light source with fluorescent tube, and it is with respect to the tungsten filament bulb, the luminous efficiency height, and surface temperature is low, the life-span is long.But compare with the LED that reaches its maturity (light emitting diode) lighting engineering, the latter is more energy-conservation, life-span longer (the LED life-span of present stage is generally greater than 50,000 hours), more environmental protection (problem that occurs mercury pollution when not having fluorescent tube discarded), surface temperature is lower during with brightness, simultaneously not having ultraviolet ray, infrared ray and radiation in the spectrum that LED produced, is typical green illumination.Just because of above-mentioned advantage, LED will become the main lighting source of daily life from now on.
The utility model content
The purpose of this utility model is to provide a kind of convenient installation, is widely used, uses the LED annular lamp tube of LED as light source.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the LED annular lamp tube, comprise by insulating materials and make lamp holder, lamp holder is provided with metal pin, lamp holder is connected to the transparent pipe of annular, be provided with circuit board in the transparent pipe, circuit board is provided with several LED, and LED is electrically connected with metal pin by the lead on the circuit board.
Described transparent pipe is engaged by the two halves that separate vertically and forms.
Owing to adopted above-mentioned structure, the utility model is simple in structure, but direct convenience be installed on the light fixture of existing annular lamp tube, the utility model is with the advantage of LED illumination, have very strong practicality and promotional value, can be widely used in family, public place etc.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of first kind of embodiment of LED annular lamp tube;
Fig. 2 is the cutaway view Amplified image of the A-A line of Fig. 1;
Fig. 3 is the structural representation of second kind of embodiment of LED annular lamp tube;
Fig. 4 is the structural representation of the third embodiment of LED annular lamp tube.
The specific embodiment
Embodiment 1
As depicted in figs. 1 and 2, LED annular lamp tube described in the utility model comprises by insulating materials and makes lamp holder 1 that lamp holder 1 is provided with metal pin 2, and metal pin 2 effects are to be inserted on the lamp socket that is complementary, and as the power supply input terminal.The interface structure that metal pin 2 is arranged and size is made with existing annular lamp tube light fixture is complementary convenient supporting existing fluorescent lighting fixture.Lamp holder 1 is connected to the transparent pipe 3 of annular, and transparent pipe 3 and lamp holder 1 are connected and fixed mode can be by bonding or fix with modes such as screws, and both also can become an integral body, and transparent pipe 3 can be made by plastics or glass, is shaped as annular.Be provided with circuit board 4 in the transparent pipe 3, circuit board 4 is positioned in the transparent pipe 3 by screens 6.Weldering is provided with several LED5 on the circuit board 4, and LED5 is electrically connected with metal pin 2 by the lead on the circuit board 4.Metal pin 2 links to each other with circuit board 4 by lead as terminals, makes the LED5 that is welded on circuit board 4 luminous.LED5 can be made up of 1 or one or more groups LED luminous tube, the power of LED and the power of quantity decision intubate and luminous intensity, and what LED was different is connected, and determines the dc source of needed different voltages.LED5 can directly be connected with dc source by metal pin 2, if with the domestic 220V of civil power, alternating voltages such as foreign 120V, 230V connect, and then will load onto in lamp holder 1 this moment by " constant current electronic transformer ", coupling correspondent voltage electric current, it is normally luminous to satisfy LED.Light then transmitted through transparent pipe 3 surfaces when LED was luminous.
Described transparent pipe 3 is engaged by the two halves that separate vertically and forms, and two halves can adopt fastening or screw or bonding fastening mode to connect.It is comparatively convenient that this structure is installed and overhauled, and opens half when maintenance or installation and get final product.
As shown in Figure 3, being shaped as of described transparent pipe 3 is square, and internal structure is identical with embodiment one.
As shown in Figure 4, described transparent pipe 3 be shaped as butterfly, internal structure is identical with embodiment one.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
Claims (2)
