Description

Technical Field

[0001] The utility model belongs to the technical field of tungsten halogen lamps, and in particular relates to an adjustable tungsten halogen lamp. Background Art

[0002] A tungsten halogen lamp is a gas-filled incandescent lamp that contains some halogen elements or halides in the filling gas. In order to make the halides generated at the lamp wall in a gaseous state, the tube wall temperature of the tungsten halogen lamp must be much higher than that of an ordinary incandescent lamp. Accordingly, the bulb size of the tungsten halogen lamp must be much smaller, and high-temperature resistant quartz glass or hard glass must be used. The evaporation of tungsten in the tungsten halogen lamp is more strongly suppressed. At the same time, the tungsten halogen cycle eliminates the blackening of the bulb, and the operating temperature and lighting efficiency of the filament can be greatly improved, and the life of the lamp is also extended accordingly. A tungsten halogen lamp requires a lamp holder during use. The traditional tungsten halogen lamp holder is relatively simple and is mainly used to install tungsten halogen lamps during use.

[0003] The existing Chinese patent with announcement number CN219226224U discloses an adjustable halogen tungsten lamp holder, including a base and a lamp holder installed on the top of the base, the top of the base is fixedly installed with a rotating seat, the rotating seat is installed on the top of the base and the lamp holder can be rotated at the same time, the top of the rotating seat is fixedly installed with the lamp holder, both sides of the bottom of the base are installed with movable sleeves, the inner wall of the movable sleeve is movably installed with an extension plate, and the extendable plate can appropriately change the overall length of the device to adjust the length of the halogen tungsten lamp, the inner side of the movable sleeve is movably installed with an extension plate, and a movable shaft is fixedly installed between the two groups of extension plates, the movable shaft is used to install the extension plate and can drive the extension plate to extend, the internal memory of the movable shaft is fixedly installed with a fixed block, and the bottom of the fixed block is fixedly installed with a bottom plate, the bottom plate can fix the device to improve the convenience of device installation, and mounting holes are distributed around the bottom plate, and the mounting holes can be used to install the device through bolts.

[0004] With respect to the above-mentioned related technologies, the inventors have found that there are at least the following problems in the technologies: the existing halogen tungsten lamp holders are generally fixed with screws, and the mounting holes of the lamp holders are opened at fixed positions. The positions of the four mounting holes cannot be adjusted according to actual needs. If the screws cannot be fixed at the positions of the mounting holes, it will be difficult to install the halogen tungsten lamp. Utility Model Content
