Ceiling lighting lamp

Abstract

The invention discloses a ceiling lighting lamp. A photocatalyst layer is smeared on the surfaces of a lampshade and a light source; a photocatalyst is irradiated by sunlight or the lamp which is turned on and can convert energy of light into positive electron holes and electrons, catalytic reaction is carried out between the positive electron holes, the electrons and water vapor and oxygen molecules in the air to generate hydroxyl radicals with ultrahigh oxidizing capacity and oxide anions, and the hydroxyl radicals can decompose bacteria, odor and oil stains attached to the surfaces of the lampshade and the light source and airborne bacteria in the air into water and harmless gases (CO and HO), so that the lamp is kept clean and the luminous flux is improved; a miniature fan is arranged in a decorative frame at the periphery of a chassis and can quicken indoor ventilation, so that the hydroxyl radicals and the oxide anions are quickened to circulate in a room, and the decomposition of the hydroxyl radicals on organic substances and partial inorganic substances, which are harmful to human bodies or the environment is quickened to achieve an effect of purifying the air.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a ceiling-absorbing or suspended ceiling lighting fixture with cleaning and sterilizing functions. Background technique [0002] Ceiling lamps and chandeliers are the main lighting equipment used in the interior, and are lighting fixtures often used in various indoor places such as homes, offices, and entertainment venues. Since the ceiling or ceiling lamps are installed at a high place, it is inconvenient to wipe. After a long time, a lot of dust and stains will accumulate on the surface, which will affect the high throughput. If the lamp can have self-cleaning ability, it will be able to solve the problem of lamp cleaning for users. [0003] Moreover, in addition to bacteria and microorganisms, which are well known to the general public, indoor environmental sanitation also includes volatile organic compounds, such as carpets, wall paints, or wooden building materials.

Problems solved by technology

[0003] Moreover, in addition to bacteria and microorganisms, which are well known to the general public, indoor environmental sanitation also includes volatile organic compounds, such as carpets, wall paints, or wooden building materials. During the manufacturing process, organic solvents and other components or substances will be used and left in the building materials. When these building materials or decoration materials are used indoors, they will gradually release harmful pollutants into the indoor air, such as formaldehyde, VOCs, etc. When indoor ventilation is poor, volatile organic compounds will continue to accumulate and become one of the sources of indoor air pollutants, causing adverse effects on human health
