Performance characteristics of double-arm road lights
Double arm road lights use light correctly to prevent glare. The light it emits should strike the specified shape on the road surface at the desired angle. The light distribution is uniform, the road surface brightness is large, and the glare is small. To reduce glare, the light can be controlled * * on top. According to the characteristics of road section form, width, vehicles, pedestrians, etc., street lamps can be used in symmetrical arrangement on both sides of the road, on both sides, on the side, and on the central suspension. Generally speaking, if the width is greater than 20 meters, Yingbin Road can be considered to be arranged symmetrically on both sides; if the width of the road exceeds 15 meters, the two sides of the road can cross. A narrower road can be set aside. In special places such as road intersections, curves, ramps, railway crossings, and pedestrian crossings, street lights are usually installed to facilitate drivers and pedestrians to identify road conditions. To illuminate entry and exit tunnels, from downtown streets to suburban roads, the driver's eyes are thought to adapt to changes in light. The power, installation height and longitudinal spacing of street lamps are important parameters of lighting design. Combining these three factors, a satisfactory lighting effect can be obtained.
The main pole of the double-arm road light is made of high-quality steel plate through a large CNC bending machine. The advanced one-time automatic closing welding equipment is adopted, the welding quality is high, and there is no grinding; the rod body has no transverse welding seam, and the surface is hot zinc, and then sprayed. We can design and manufacture various art forms according to the individual needs of customers to increase the viewing of street lamps. The overall structure has strong corrosion resistance, economical and practical, smooth surface, durable color and good self-cleaning ability. Generally, 100W ~ 400W high-pressure sodium lamps are used, which are more economical and practical high-power LEDs, and new energy-saving light sources such as tri-color energy-saving lamps can also be used. For city centers, commercial centers and other personal color identification requirements, for commercial streets required for the use of metal halide lamps.
Double arm road lights are widely used in stadiums, ports, squares, road interchanges, railway stations, airports and large garages. It has the advantages of large lighting area, good lighting effect, concentrated light source, uniform lighting, small glare, easy power supply control, and convenient maintenance. Made of high-quality steel plate, it is divided into cone type and polygon type. Install a field kit or insert. The lamp pole is hot-dip galvanized after rust, and the surface is sprayed for protection. It is installed at the bottom of the bar and consists of a complete set of hoists, which can be divided into two types: long hanging type and hook type. The hook type can automatically take out the lamp panel, and the wire rope cannot bear the pressure for a long time. The aluminum casting shell adopts fully enclosed casting, and the power is 250W ~ 1000W.
