Fluorescent lamp and method for adjusting color temperature and luminous flux of fluorescent lamp

Abstract

The invention is applicable to fluorescent lighting, and provides a fluorescent lamp and a method for adjusting color temperature and luminous flux of the fluorescent lamp. The fluorescent lamp comprises a lamp housing, fluorescent powder, a first discharge lamp, a second discharge lamp and a voltage adjusting device, wherein the fluorescent powder is coated on the inner surface of the lamp housing; the first discharge lamp and the second discharge lamp are arranged in the lamp housing; the voltage adjusting device is connected with the first discharge lamp and the second discharge lamp respectively; and the fluorescent powder is three-primary-color fluorescent powder. The method comprises the following steps of: generating first exciting light and second exciting light by the first discharge lamp and the second discharge lamp in the lamp housing of the fluorescent lamp; and adjusting intensities of the first exciting light and the second exciting light through the voltage adjusting device so as to adjust the color temperature and the luminous flux of the fluorescent lamp respectively. By adopting the method, the color temperature and the luminous flux of white light emitted by the fluorescent lamp are adjusted in wide ranges, meanwhile, luminous efficiency and color rendering property of the fluorescent lamp are not influenced, and the fluorescent lamp is suitable for various occasions.

Description

technical field [0001] The invention belongs to lighting technology, in particular to a fluorescent lamp and a method for adjusting the color temperature and luminous flux of the fluorescent lamp. Background technique [0002] Mercury in fluorescent lamps and cold-cathode fluorescent lamps is a liquid heavy metal that is volatile and harmful to the environment. The production and disposal of cold-cathode fluorescent lamps will pollute the environment. The development of mercury-free fluorescent lighting is a direction for the development of lighting technology. Recently, a trichromatic fluorescent lamp has appeared, whose luminous flux can be adjusted, but the color temperature cannot be adjusted, which limits its application. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a fluorescent lamp capable of adjusting color temperature and luminous flux and a method for adjusting the color temperature and luminous flux o...
