Abstract

The invention belongs to the technical field of lamps and lanterns, specifically a clip-type lighting device, which includes a clip-type base, a lamp cap and a support rod; the clip-type base includes an upper base, a lower base hinged to the upper base, and Torsion spring; also includes a pressing air bag, a supporting air bag and an extrusion unit; the bottom of the upper base is fixed to a hemispherical supporting air bag, and the top is fixed to a hemispherical pressing air bag; a No. 1 airway is arranged on the upper base; An extruding unit is arranged on the upper base; the extruding unit includes a slider and a slide bar, and a chute is symmetrically arranged on the upper base; sliders are slidably installed in the chute; the two sliders are connected the sliding rod; the present invention squeezes the gas in the pressing airbag into the supporting airbag through the extrusion unit, so that the supporting airbag expands and protrudes, thereby increasing the force of the torsion spring when the clamping base is clamped, and improving the clamping force. Holding strength, thereby avoiding the phenomenon of the desk lamp falling off.

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...
