A kind of energy-saving lamp for indoor use

Abstract

This application relates to an energy-saving lamp for indoor use, which includes a lamp holder, a lampshade, a light bulb arranged at the bottom of the lamp holder, and a prefabricated board arranged on the ceiling. There is an empty slot in the prefabricated board, and a There is a through hole on the top of the lamp holder. The movable plate passes through the through hole and extends into the empty slot. The inside of the airbag is filled with inert gas, the bottom of the airbag is fixed on the inner wall of the bottom of the cavity, the side of the airbag close to the movable plate is provided with a damping sheet, and the damping sheet is offset against the movable plate, and the airbag is connected with a driving piece that drives the damping sheet to move. . The application has better energy-saving and heat-insulating effects.

Description

technical field [0001] The present application relates to the technical field of energy-saving lamps and lanterns, in particular to an energy-saving lamp for indoor use. Background technique [0002] At present, LED energy-saving lamps are compact fluorescent lamps with built-in ballasts. Compared with incandescent lamps, they have higher current utilization efficiency and more energy-saving effects. Indoor energy-saving lamps are energy-saving lamps installed indoors. . Among the indoor energy-saving lamps, ceiling-mounted downlights are a relatively common type, which are embedded on the ceiling to save space and provide better lighting. [0003] The prior art such as a new type of ceiling LED downlight disclosed in the application document with the publication number CN204717516U includes a lamp tube, a ceramic light-transmitting decorative ring body and a ferrule. There is a drive power supply at the rear end, a screw hole is provided in the lamp tube, a reflector is p...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the embedded energy-saving lamps will open holes in the ceiling for the installation of the energy-saving lamp shell, but the design of the slots in the ceiling will damage the structure of the ceiling to a certain extent. The structure affects the heat insulation effect of the ceiling; when the energy-saving lamps are turned off and the air-conditioning or heating is turned on indoors, the design of the slots on the ceiling will accelerate the heat exchange between the inside and the outside, and the weakening of the heat insulation effect will cause waste of air-conditioning or heating
