Problems solved by technology

[0003] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the light irradiation range of the desk lamp is relatively small and concentrated, so it will not affect the light of the whole room, but the effect is limited around the desk lamp, so the illumination of the desk lamp is limited. There is a blind angle of light, which cannot be illuminated, which also brings a lot of inconvenience to the user, and affects the work and study of the user when the line of sight is dark, and a LED desk lamp with an adjustable light angle is proposed

Abstract

The invention discloses an LED desk lamp with adjustable illumination angle, which comprises a base, a placement groove is arranged above the base, a mounting box is arranged in the placement groove, a rotating cavity is arranged in the mounting box, and the rotating cavity The inner top is provided with a first bevel gear, and the inner wall of one side of the rotating chamber is provided with a second bevel gear meshed with the first bevel gear, and one side of the base is provided with a rotating port communicating with the rotating chamber. A first rotating rod is inserted into the rotating port, and one end of the first rotating rod is connected to the second bevel gear through the rotating port. The installation box is provided with an installation cavity, and two symmetrically arranged in the installation cavity. a third bevel gear, and a second rotating rod is arranged between the two third bevel gears. The invention realizes random switching of the lighting angle of the table light, and even the dead angle that cannot be irradiated by the light can be realized by turning the rotating block, which meets the needs of the user for adjusting the lighting angle under any circumstances.

Description

technical field [0001] The invention relates to the technical field of LED desk lamps, in particular to an LED desk lamp with an adjustable illumination angle. Background technique [0002] In modern life, a desk lamp is a necessity for study and work, and the desk lamp is mainly placed on a desk or a dining table for lighting purposes. The light irradiation range of the desk lamp is relatively small and concentrated, so it will not affect the light of the whole room, but the effect is limited to the surroundings of the desk lamp, so the light of the desk lamp has blind spots and cannot be illuminated, which also brings many problems to the user. Inconvenience affects the user's work and study when the line of sight is dark, so there is an urgent need to design an adjustable LED desk lamp with an illumination angle. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the light irradiation range of...
