Description

Daylight environmental protection and energy saving LED lighting

technical field

The utility model relates to a lamp for indoor environment lighting, in particular to a lamp that can be used as a lighting lamp for hallways, toilets, corridors, guest rooms, corridors and other environments.

Background technique

Existing lighting lamps, such as fluorescent lamps and incandescent lamps, generally have technical problems such as high power consumption, high waste tube rate, and short service life. Taking corridor lighting as an example, the current corridor light source still uses traditional incandescent lamps. Due to limited Due to power consumption requirements, only 10-15w low-wattage incandescent lamp holders can be used. The brightness itself is very low. If a decorative cover is installed on the outside, the brightness will be even more seriously lost, resulting in dim corridors and obviously insufficient lighting capabilities. . Generally speaking, the lighting power index of incandescent lamps is limited by the lighting brightness and there is no room for further reduction. In addition, both incandescent lamps and fluorescent lamps have obvious problems of glare and flicker, which make people feel uncomfortable. The application of LED light-emitting tubes has gradually expanded to the field of lighting, but most of the products still use LED light-emitting tubes for direct beam lighting, and the lighting coverage is small, and they mainly use DC power supply such as batteries, which cannot be directly applied to AC power supply environments, or The structure of AC to DC power supply constitutes a relatively complicated technical problem.

Contents of the invention

The purpose of the invention of the utility model is to provide a sunlight environment-friendly and energy-saving LED lighting lamp with low power consumption and high brightness. The technical scheme of the solar environment-friendly and energy-saving LED lighting lamp provided by the utility model mainly includes: a solar-environmental protection and energy-saving LED lighting lamp, which includes an LED light-emitting tube as a light source, a lampshade and a base for the light source. Several LED light-emitting tubes are connected in series or in parallel to form an LED light-emitting tube group. The LED light-emitting tube group is electrically connected to the control circuit, and its lampshade is coated with or mixed with fluorescent materials.

In the above-mentioned overall technical solution, the control loop of the LED light-emitting tube group is composed of a full-bridge rectifier circuit and a filter capacitor, and its circuit board and the LED light-emitting tube group are fixed and assembled on the base.

The technical scheme of the solar environment-friendly and energy-saving LED lighting lamp disclosed by the utility model adopts an LED light-emitting tube group composed of several LED light-emitting tubes as a light source. The lampshade combination of powder material can completely homogenize the straight beam of LED light-emitting tube and form scattered light, not only will not lose the brightness, but also the lighting brightness is more thorough and stable, the lighting distance is long, and it has the effect of sunlight irradiation, and No glare, no flicker, people feel comfortable and make ambient lighting bright. The technical solution can also be widely used as lighting lamps for various indoor environments, such as lighting lamps for entrance halls, toilets, balconies and bedsides.
