In order to cater to the market demand and people's use habit, existing LED fluorescent tube generally all is the mounting means that follows fluorescent tube, be made into tubulose and two terminals respectively are installed at two ends, after then in the mount pad of the lamp bracket that terminal is inserted into, fluorescent tube is rotated to the just installation of suitable angle.The LED fluorescent lamp of Xiao Shouing mainly is divided into following two classes in the market, and the first kind is just installed on the basis of existing light fixture, so need to change circuit when mounted, it is low that efficient is transformed in installation, and poor stability, and installation process wastes time and energy, and cost increases; Second class is the same two ends contact pin that utilizes with traditional fluorescent lamp, the contact pin of one end connects live wire, and the contact pin of the other end connects zero line, in being installed to the traditional fluorescent lamp mount pad after, utilize the current loop of traditional fluorescent lamp to be communicated with fluorescent lamp, make the LED fluorescent lamp luminous, the shortcoming of this technology is contact pin at one end, after particularly live wire end contact pin has been installed, when carrying out other end installation again, because the other end is charged, causes and advance to penetrate spark when installing easily, even also have the possibility of electric leakage.If because this reason is changed whole lamp socket, then cost is too high again.
Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Fast Installation, safe ready, low-cost LED fluorescent lamp realized.
For reaching above purpose, the utility model provides a kind of LED fluorescent lamp, comprise housing, be arranged on described enclosure interior circuit board, be arranged on a plurality of LED on the described circuit board, be arranged on the joint contact pin at described housing two ends, the power interface of described circuit board is connected with power line, and the other end of described power line passes and is connected with a plug from described housing.
Further improvement of the utility model is that power supply is an alternating current, and the fire-wire interfaces of described power line and described circuit board is connected with the zero line interface.
Further improvement of the utility model is that the fire-wire interfaces of described circuit board and zero line interface are arranged on same end, and described power line is connected with the same end of circuit board.
Further improvement of the utility model is that power supply is a direct current, and the positive pole of described power line and described circuit board connects
Mouth is connected with the negative pole interface.
Further improvement of the utility model is that the anode interface of described circuit board and negative pole interface are arranged on same end, and described power line is connected with the same end of circuit board.
Further improvement of the utility model is, described housing is provided with for described power line from hole that enclosure interior passes near the diapire of end.
Further improvement of the utility model is that described power line is fixedly connected by the method and the described circuit board of welding.
Further improvement of the utility model is that described contact pin outer surface is provided with insulating protective layer.
Owing to adopted above technical scheme, the utility model carries out the fixing of fluorescent lamp by using the joint contact pin to insert the fluorescent lamp mount pad on the one hand, make quick and easy for installation, having avoided that also the fluorescent lamp mount pad is transformed the use cost that causes raises, on the other hand because contact pin is no longer charged, solved the problem of advancing to penetrate spark and electric leakage when prior art is installed easily, so also safety and convenient more when installing.
