Lighting lamp and brightness control method thereof

Abstract

The invention relates to an illumination lamp. According to the illumination lamp, lamp heads are internally provided with at least two color temperature light sources, and a shell is internally provided with a light control, a gear switch, a gear shifting assembly and a rotary knob; the gear shifting assembly is rotatably arranged on the shell, provided with a first light transmitting part for incidence of an external light source and connected with the gear switch; the rotary knob is rotatably arranged on the gear shifting assembly and can shield or partially shield the first light transmitting part. According to the illumination lamp, through the rotary knob arranged on the gear shifting assembly, the incidence of light rays or not in an end cover and the intensity of the light rays canbe controlled, and whether or not the illumination lamp is turned on can be selected according to demands; meanwhile, through the cooperation of the gear shifting assembly and the gear switch, the color temperature of the light rays emitted by the whole illumination lamp can be conveniently switched, in addition, a switch for controlling the switch-on and switch-off of the illumination lamp and the switch for controlling a color temperature gear position are integrated, the space of the whole illumination lamp can be saved, and the operation is facilitated. The invention further relates to abrightness control method of the illumination lamp.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a lighting lamp and a brightness control method thereof. Background technique [0002] The lighting in many public places often uses manual switches to control the lighting of the lamps. Although the manual switch can realize the switch of the lamps, it needs to be actively turned on when the light is dim and turned off when the light is bright. Obviously, it is very inconvenient. With the development of lighting technology , there are lamps with light control function on the market. This type of lamp can judge whether to turn on the lighting function by detecting the intensity of ambient light, which is more intelligent and convenient. For example, the Chinese invention with the patent number CN201320739824.1 The patent "An External Control Device for Light-Controlled Light Switch" discloses an intelligent light control device. Control the turntable to adjust the light transmi...

[0002] The lighting in many public places often uses manual switches to control the lighting of the lamps. Although the manual switch can realize the switch of the lamps, it needs to be actively turned on when the light is dim and turned off when the light is bright. Obviously, it is very inconvenient. With the development of lighting technology , there are lamps with light control function on the market. This type of lamp can judge whether to turn on the lighting function by detecting the intensity of ambient light, which is more intelligent and convenient. For example, the Chinese invention with the patent number CN201320739824.1 The patent "An External Control Device for Light-Controlled Light Switch" discloses an intelligent light control device. Control the turntable to adjust the light transmission area. Although this device and the lights on the related market can be turned on and off intelligently, public places such as squares often have a large flow of people and require brighter lights with high color temperature. However, some places such as shopping malls and kitchen windows that require high color rendering require milder low-color-temperature lighting. The above-mentioned lighting applications for publication cannot adjust the color temperature, resulting in a single color temperature of the lighting, which cannot meet the needs of use in many cases.
