Abstract

The invention belongs to the technical field of lamps, and particularly relates to a clamp-on illuminating device. The clamp-on illuminating device comprises a clamp-on base, a lamp cap and a supporting rod, wherein the clamp-on base comprises an upper base, a lower base hinged to the upper base and a torsion spring. The clamp-on illuminating device further comprises a pressing air bag, a supporting air bag and a pressing unit, wherein the bottom of the upper base is fixedly connected with a hemispherical supporting air bag, and the top of the upper base is fixedly connected with a hemispherical pressing air bag. The upper base is provided with a first air channel and the pressing unit which comprises sliding blocks and sliding rods, sliding grooves are symmetrically formed in the upper base, and wherein the sliding blocks are arranged inside the sliding grooves in a sliding mode, and each sliding rod connect two sliding blocks. According to the clamp-on illuminating device, air in thepressing air bag is pressed into the supporting air bag through the pressing unit, so that the supporting air bag is expanded and protrudes, acting force of the torsion spring during clamping of theclamp-on base is increased, clamping force is improved, and the phenomenon that a table lamp falls off can be avoided.

Description

technical field [0001] The invention belongs to the technical field of lamps, in particular to a clip-type lighting device. Background technique [0002] Desk lamp is a kind of lamp, and it is mainly placed on writing desk or dining table, for the usefulness of lighting when reading, studying. Its function is to concentrate the light in a small area, which is convenient for work and study. Generally, the light bulbs used in desk lamps are incandescent lamps, energy-saving bulbs, and eye-protecting desk lamps that are popular on the market. Some desk lamps also have "emergency function" that is, their own power supply, which is used for emergency lighting during power outages. When the base of the desk lamp was small, the contact surface with the desk or the dining table was small, and the installation of the desk lamp was not reliable, which affected the use of the desk lamp. In order to enhance the firmness of the desk lamp installation, it is necessary to increase the ba...
