Lighting device capable of conveniently adjusting lighting range and lighting method thereof

Abstract

The invention discloses a lighting device capable of conveniently adjusting a lighting range and belongs to the technical field of lighting lamps. The lighting device comprises a lamp holder, whereina protection cover is mounted at the bottom of the lamp holder; heat dissipation holes I are formed in the left side and the right side of the protection cover; a U-shaped frame is mounted at the bottom of the lamp holder; a motor is mounted on the right side of the bottom of the lamp holder; a driving bevel gear is mounted at the bottom output end of the motor; the bottom of the driving bevel gear is engaged with a driven bevel gear; a rotating rod is transversely mounted on the driven bevel gear; a lampshade is mounted at the bottom of a movable block; a glass plate is mounted at the bottomof the lampshade; a light plate is mounted at the top of an inner cavity of the lampshade; an LED lamp is mounted at the bottom of the light plate. According to the lighting device capable of conveniently adjusting the lighting range, the lampshade moves in a direction close to a through hole, so that the lighting range is expanded after the LED lamp passes through the through hole; the lighting range is reduced by enabling the lampshade to be away from the through hole; different lighting requirements can be met; the lighting range can be conveniently adjusted.

Description

technical field [0001] The invention relates to the technical field of illuminating lamps, in particular to an illuminating device and an illuminating method for adjusting the illumination range. Background technique [0002] LED lights mainly provide lighting. At present, the irradiation range of traditional LED lights is often fixed and cannot be adjusted, and thus cannot meet some requirements for adjusting the lighting range, causing inconvenience in use, such as some KTVs and entertainment places. The requirements are relatively high, and the lighting can set off the atmosphere of the scene. Traditional LED lights cannot meet the demand. Therefore, we propose a lighting device and lighting method that is convenient for adjusting the lighting range. Contents of the invention [0003] The object of the present invention is to provide an illuminating device and an illuminating method that can easily adjust the illumination range, so as to solve the problems raised in the...
