The present invention relates to a lamp for lighting purposes, wherein lamps for illumination purposes are roughly divided into lamps having a glass tube type lamp having filaments and lamps having LEDs.

FIG. 1 is a view showing a conventional automotive interior lamp, which is a filament type lamp for an automobile interior lamp, as shown in FIG.

Such a lamp is advantageous in that the production cost is low due to the use of filaments, while the process of forming the vacuum by embedding the filament 12 in the glass tube 10 and the process of maintaining the electrical connection with the lead terminal 13 extending from the filament at both ends of the glass tube And a fixing portion 15 for pressing and fixing the lead terminal 13 protruding out of the metal tube 14 by covering the metal tube 14 so as to achieve a mechanical coupling structure at the same time, The metal tube 14 is inserted into the terminal of the interior lighting device.

However, such a filament type interior light has a problem in that it is not easy to manufacture due to the mixing process of the glass tube and the heterogeneous process such as the mechanical forging and the pressing factory, and there is a problem in that the service life is short, And problems caused by glass tube breakage due to carelessness during use.

FIG. 2 is a kind of LED lamp developed to replace an existing filament type interior lamp, and has been registered in Korean Patent No. 1108108 by the present applicant.

This is achieved by mounting an LED lamp 22 SMD-mounted on the PCB 20 and various electronic components for driving an LED lamp and forming lead terminals 23 at both ends of the PCB 20 to form a long The lead terminals 23 exposed through the cover are covered with covers 24 and 25 to protect the mounting parts on the upper and lower sides of the metal tube 26 and are electrically connected by the solder 27 through the metal tube 26 And the metal tube 26 is press-fitted into the upper and lower covers 24 and 25 so as to be mechanically coupled.

However, in the interior lamp having such an LED lamp 22, the lead terminal 23 is inserted into the interior light terminal and the lead terminal is fixed with solder by interposing the metal material tube 26 making electrical and mechanical connection, so that the manual process is inevitable And there is a disadvantage that excessive investment is required for the facility even if it is automated.

Further, if the proper pressure is exerted in the process of pressurizing and deforming the metal fitting tube by the joining structure of the resin material cover and the metal tube, working conditions such as breakage of the resin material cover or loosening of the resin material cover, There is a difficult problem.

In addition to the conventional technology shown in the drawings, various LED lamps for interior lighting are well known and are the same as the prior art documents set forth below.
