Description

A reflector for floodlights used in high salt fog areas

Technical Field

The invention belongs to the technical field of lamps in high salt fog areas such as seaports, docks, and oceanariums, and relates to a reflector for a floodlight, in particular to a reflector for a special floodlight in high salt fog areas.

Background technique

A lamp is a common lighting tool, which uses the light emitted by a light source to illuminate the surrounding environment. Its structure is: including a light source, a light converging device and a circuit device. The light emitted by the light source is converged by the light converging device to illuminate the ground or space below. The above-mentioned light source initially often used light sources such as high-pressure sodium lamps, but these light sources are relatively power-consuming. After research, people have developed LED lamps. This type of lamp has the advantages of low power consumption and high brightness, and is widely used in various occasions. However, traditional LED lights also have problems: 1. Although the brightness of LED lights is high, the range is short. Although the range can be increased by adding reflectors, lenses and other light converging devices, it is still possible to further improve it; 2. The light emitted by LED lights after converging has a greater stimulation to the human eye, that is, the glare index is high. Bright light can cause people to be affected by strong light, especially the glare index of the converging structure of ordinary lenses is very high, which will cause temporary blurred vision of the eyes of operators working under the lights, which has a great impact on safety work; 3. When used in some high salt fog areas such as ports, docks, and oceanariums, due to the relatively humid environment, there are a large number of salt fog particles, which have a greater impact on the light emitted by LED lights, further reducing its irradiation brightness and irradiation distance. After searching, some patents and products have disclosed some low-glare lamps, and their own structures can be further optimized, and the final use effect can be further improved.
