Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and particularly relates to a wall lamp. Background Art

[0002] A wall lamp is an auxiliary lighting and decorative lamp installed on a wall. Its structure generally includes a lamp body and a base, and the base is fixed on the wall. However, the existing wall lamps often have the following problems in the using process: The lamp body includes a housing, a lighting light source assembly installed on the housing. The lighting light source assembly includes a lamp board, a reflector and a lamp head. The lamp board and the reflector are installed inside the housing. The lamp head generally only includes a light-transmitting cover, and the lamp head is installed at the outer end of the housing, that is, the lighting light source assembly is a split structure. The split-structure lighting light source assembly has the problem of troublesome installation. When the housing needs to be replaced, the entire lamp body needs to be replaced. Once the entire light source assembly is installed on the lamp head, when the housing needs to be replaced, only a new housing needs to be replaced. At present, after the wall lamp is installed, there is the problem of inconvenient angle adjustment.

[0003] For this reason, a wall lamp with the publication number of "CN206130737U" includes a housing, an LED driver installed inside the housing, a base installed at the bottom of the housing, a bottom cover installed at the rear end of the housing, and a lamp head installed at the front end of the housing. A lighting light source assembly is installed inside the lamp head. The lighting light source assembly includes a lamp board, a reflector and a light-transmitting plate arranged in sequence from inside to outside. An LED light source is arranged in the middle of the lamp board. A convex strip is arranged at the rear side of the bottom of the base, and a positioning plate is hinged to the convex strip through a rotating shaft. Thus, the angle adjustment of the wall lamp is flexible and the light source assembly is installed on the lamp head.

[0004] However, for the above wall lamp, although a lighting light source assembly is installed inside the lamp head, the lighting light source assembly includes a lamp board, a reflector and a light-transmitting plate arranged in sequence from inside to outside, and an LED light source is arranged in the middle of the lamp board. The entire light source assembly is installed on the lamp head. When the housing needs to be replaced, only a new housing needs to be replaced. There are still the following obvious defects in the using process: The light-transmitting plate in the above wall lamp is fixed at one end of the reflector. Although the position of the light can be changed through an adjusting mechanism, it can only irradiate linearly, so the light-transmitting plate cannot be telescopically adjusted to increase the range of the light irradiation.

After the telescopic light-transmitting cover extends to the bottom of the cylindrical lamp housing at the maximum, the pressing top block is pressed against the cylindrical lamp housing by rotating the threaded locking posts, so as to realize the locking and fixing of the cylindrical lamp housing, so that the light source generated by the annular lamp board can be irradiated on the cylindrical lamp housing in a large range, and then the range of the light source emitted from the cylindrical lamp housing becomes larger, so that the wall lamp can adjust the irradiation range of the light source.

[0015] Through the combined use of the annular fixing plate, the plug-in electrical cylinder base, the annular lamp board and the power connection pin, after the annular lamp board fails, the telescopic light-transmitting cover can be pulled out to pull out the power connection pin on the annular lamp board from the plug-in electrical cylinder base, so as to disconnect the connection with the external power wire, and the annular lamp board can be electrically connected in a pluggable manner, so that the annular lamp board can be disassembled and replaced conveniently through the above structure, and further improve the convenience of later maintenance and replacement of this wall lamp.
