Analysis of road lamps installed in pole lighting

When the road is relatively wide, it is not very effective to increase the elevation angle of the luminaire in order to improve the lighting in the road. Because it only increases the amount of light that the luminaire reaches the opposite road surface, its light is difficult to reflect into the driver's eyes, so the brightness does not increase proportionally. In fact, whether the visual function or the comfortable road brightness is more important than the illuminance, and the chance of glare is increased due to the elevation angle, this method is not preferable. Similarly, the spotlights in the toll area must also strictly use asymmetric light distribution lamps to minimize the elevation angle of the lamps and reduce glare pollution.

Road luminaires, usually installed with pole lighting, are more convenient to meet lighting requirements, but in some cases, such as multi-lane, multi-level, parallel or intersecting roads, too many erected poles will obscure the line of sight and affect The overall landscape, and easy to produce light pollution to adjacent lanes. Most of the wall-mounted lighting with low installation height is applied to both sides of important landscape roads. These landscape areas do not want to have a light pole, but require that the clearance be complete, which requires the fixture to be installed in a protective wall or on a soundproof wall.

The TG170 was originally designed for the main entrance and exit road lighting of the Shanghai Pudong International Airport terminal building. The luminaire is designed to be embedded in the anti-collision wall, 0.5m from the ground. A 70W low-power high-pressure sodium lamp source is used. The illuminating light of the luminaire is quickly cut off at an angle above the horizontal level, effectively avoiding glare. It ensures that the road surface achieves the required illumination without causing light stimulation to the driver, and at the same time fundamentally eliminates the negative impact of the damaged landscape caused by the poles. It is a kind of street lamp with a completely different performance. A unique class of road lighting. The product can fully display the curve of the bridge during the day, and the performance layout is spectacular; at night, it can obtain novel and unique lighting effects, eliminate the light pollution, and maximize the landscape requirements of the airport terminal area.

The TG172 is a special luminaire that combines functionality and decoration. This kind of luminaire uses 28W-T5 fluorescent lamp as the light source. It is a long-shaped lamp body. The luminaire reflector is bent 13 times after accurate calculation by computer to achieve the best lighting effect. At the same time, the lamp is installed on the upper part of the luminaire to avoid glare. The lamps are densely arranged, very beautiful and highly inductive. The luminaire can also be made into a light transmission on the back side to form a light strip externally. One of the main limitations of low-mounted luminaires is that the roads should not be too wide and can only be used on roads within two lanes, and the investment is much higher than ordinary pillar lighting.
