Light reflecting device for special light projection lamp for high-salt-fog region

Abstract

The invention relates to a light reflecting device for a special light projection lamp for a high-salt-fog region. The light reflecting device comprises an upper opening and a lower opening. The inneredge of the light reflecting device is a curved surface which is gradually contracted from the lower end to the upper end. In the light reflecting device, a light gathering overall structure is formed through the mutual cooperation of the inner edge of the curved surface, convex arc surfaces, arc-shaped sections and various dimensions. According to the result of a test, the illuminance of the special light projection lamp is two or more times that of a similar product in the market under the conditions of the same power and the same distance, the glare index is relatively low, the special light projection lamp is particularly suitable for the high-salt-fog regions such as harbors, wharves and aquariums, and the requirements of the high-salt-fog regions for the ground illuminance and the glare can be met.

Description

technical field [0001] The invention belongs to the technical field of lighting fixtures in high-salt spray areas such as seaports, wharves, and aquariums, and relates to a reflector for floodlights, in particular to a reflector for special floodlights in high-salt spray areas. Background technique [0002] A lamp is a common lighting tool, which uses the light emitted by the light source to illuminate the surrounding environment. Its structure is: including a light source, a light converging device and a circuit device. The ground or space below. The above-mentioned light sources often use high-pressure sodium lamps and other light sources at first, but these light sources consume more power. After research, people have developed LED lights. This type of light has the advantages of low power consumption and high brightness, and is widely used in various kind of occasion. However, there are also problems with traditional LED lights: 1. Although the brightness of LED lights...

AI Technical Summary

Problems solved by technology

However, there are also problems with traditional LED lights: 1. Although the brightness of LED lights is high, the range is short. Although the range can be increased by adding light converging devices such as reflectors and lenses, there is still the possibility of further improvement; 2. .The light emitted by the LED lights after converging is very irritating to human eyes, that is, the glare index is high, and the bright light will cause people to be affected by strong light, especially the converging structure of ordinary lenses. The eyes of the operating personnel are temporarily blurred, which has a great impact on safety work; 3. When used in areas with high salt fog such as ports, docks, and aquariums, there is a large amount of salt due to the humidity in the environment. Fog particles have a greater impact on the light emitted by LED lights, further reducing its illumination brightness and illumination distance
