Abstract
The utility model discloses an LED (Light Emitting Diode) lamp tube structure without an external power supply, comprising a lamp tube. An LED lamp panel is installed in the lamp tube, and welded with a driving power supply and a plurality of LED lamps. In the utility model, the driving power supply is fixedly welded on the LED lamp panel, so that the power supply and the LED lamp form a whole body and are constructed on a same substrate together, therefore, the installation and the process are convenient, and the processing cost is lowered simultaneously.
Description
Technical field
The utility model belongs to the LED lighting field, and what be specifically related to is the LED fluorescent tube, particularly a kind of LED lamp tube structure that need not external power supply.
Background technology
Fluorescent lamp is as cold light source, and is more energy-conservation than conventional incandescent, therefore is widely used in industry and domestic lighting, and accessories such as the lamp socket supporting with it, lamp bracket and lamp box have formed standard.Along with the development of new-type light source led, it is inevitable that its application at lighting field has become.
LED lamp type and traditional fluorescent lamp greatly differ from each other at present; Therefore need it be designed to the fluorescent lamp shape; But owing to present LED fluorescent lamp can only can't directly be received in the electric main and use through direct current supply, therefore when the LED fluorescent tube uses; Need connect an external power supply in the outside of fluorescent tube or an independently power supply is set in fluorescent tube, to realize converting alternating current to direct current.
But connect an external power supply in that fluorescent tube is outside, need adjust, install cumbersome and cost is high existing fluorescent lamp installation system; And an independently power supply is set in fluorescent tube, and then need in the middle of whole fluorescent tube, seek the position that is used to settle this power supply, what not only processing technology bothered but also processing cost is also relative is higher.
The utility model content
For this reason, the purpose of the utility model is to provide a kind of LED lamp tube structure that need not external power supply, to solve present employing external power supply and fluorescent tube built-in power existing installation processing trouble and the high problem of cost.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
A kind of LED lamp tube structure that need not external power supply comprises fluorescent tube (1), and a LED lamp plate (2) is installed in the said fluorescent tube (1), is welded with a driving power (3) and a plurality of LED lamp (4) on this LED lamp plate (2).
Wherein said driving power (3) includes rectifier bridge reactor core sheet (6) and LED chip for driving (7), and said rectifier bridge reactor core sheet (6) is connected with above-mentioned LED lamp (4) through LED chip for driving (7).
Be provided with a draw-in groove (5) in the wherein said fluorescent tube (1), said LED lamp plate (2) fixed card is embedded in this draw-in groove (5).
The utility model is fixedly welded on driving power on the LED lamp plate, makes power supply and LED lamp form an integral body, and common framework greatly facilitates and installs and processing on same substrate, has also reduced processing cost simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the utility model LED lamp panel structure sketch map.
Identifier declaration among the figure: fluorescent tube 1, LED lamp plate 2, driving power 3, LED lamp 4, draw-in groove 5, rectifier bridge reactor core sheet 6, LED chip for driving 7, heat dissipating housing 8, diffuser 9.
The specific embodiment
For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
See also Fig. 1, shown in Figure 2, Fig. 1 is the structural representation of the utility model; Fig. 2 is the utility model LED lamp panel structure sketch map.The utility model provides a kind of LED lamp tube structure that need not external power supply, is used to solve present employing external power supply and fluorescent tube built-in power existing installation processing trouble and the high problem of processing cost.
Wherein this need not the LED lamp tube structure of external power supply; Include fluorescent tube 1, be provided with draw-in groove 5 in the said fluorescent tube 1, be equipped with a LED lamp plate 2 in this draw-in groove 5; Be welded with a driving power 3 and a plurality of LED lamps 4 on the described LED lamp plate 2, and parallel connection or series connection mutually between these LED lamps 4.
Above-mentioned rectifier bridge reactor core sheet 6 is connected to outside alternating current through electrode; Be used for converting alternating current to direct current; LED chip for driving 7 then drives a plurality of LED lamps 4 that are welded on the LED lamp plate 2 through direct current, so that these LED lamps 4 can be normally luminous.
The utility model with driving power and LED lamp frame on same LED lamp plate; When carrying out the welding of LED lamp; Can rectifier bridge reactor core sheet in the driving power and LED chip for driving together be welded on the LED lamp plate; Greatly made things convenient for processing, when having avoided subsequent installation, need independent current source be installed in fluorescent tube or outside fluorescent tube, install the trouble of external power source additional.
In addition, the utility model adopts welding manner that driving power is fixed on the LED lamp plate, has avoided the follow-up problem that headspace is settled power supply in fluorescent tube, has reduced the difficulty and the cost of processing, has improved production and installation effectiveness.
More than be that a kind of LED lamp tube structure that need not external power supply that the utility model is provided has carried out detailed introduction; Used concrete example among this paper the structural principle and the embodiment of the utility model are set forth, above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
Claims (3)
