Road lights

The road is the artery of the city. The main lighting is a street light, which is a lighting device that is set on the road to provide necessary visibility for the vehicle and pedestrians at night. (between: 0667744.com). (Cement guardrail road lights can improve traffic conditions, reduce driver fatigue, and help improve road traffic capacity and ensure traffic safety. Garden lights, landscape lights and street lights form a three-dimensional lighting pattern, enhance the road decoration effect, beautify the city night scene, also Can make up for the lack of road light illumination.
Road lamps need reasonable light distribution, and their light sources have the best longevity, and they are used for years without maintenance. High luminous efficiency, good color rendering, and the ability to start normal work instantly under ultra-low temperature conditions. Currently, incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps, low-pressure sodium lamps, electrodeless lamps, metal halide lamps, and fluorescent lamps are common among road lamps. At present, the main products of street light sources are still high-pressure sodium lamps. In recent years, the state has vigorously promoted energy-saving and emission reduction, and electrodeless lamps are new light sources compared to traditional light sources. Electrodeless lamps can achieve better road surface uniformity.
Road lights should use light energy rationally to prevent glare. The light emitted by it should be irradiated along the required angle and fall onto the road to be a specified pattern. The light is evenly distributed, the road surface is bright and the glare is small. To reduce glare, light distribution can be controlled above the maximum light intensity. According to the form of the road section, the width, the situation of the vehicle and pedestrians, the road lights can be symmetrically arranged on both sides of the road, staggered on both sides, and arranged on one side and centrally suspended on the road. In general, roads and welcome roads with a width of more than 20 meters can be symmetrically arranged on both sides; where the width of the road is more than 15 meters, staggered arrangements on both sides can be considered; narrower roads can be arranged on one side.
At road intersections, corners, ramps, railroad crossings, crosswalks and other special locations, road lights are generally required to facilitate the identification of road conditions by drivers and pedestrians. Illumination in the transitional sections between the inner and outer sections of the tunnel and from the urban streets to the suburban roads requires consideration of the adaptability of the driver’s eyes to light changes. The power, installation height and vertical spacing of road lights are important parameters for the design of light distribution. Combine these three factors to get a satisfactory lighting effect.

Working principle: the sun shines on the current generated by the solar battery plate to charge the battery through the controller, and the battery electricity is used by the controller to become a direct current supply (electrical load), or to be used as an alternating current for the load by the inverter. The solar photovoltaic system consists of a solar panel (group), a solar controller, and a battery (group). If the output power is AC 220V or 110V, an inverter must also be configured. In the specific design of system engineering, the following factors should be considered:

1. The actual total power and usage time of the load (electrical appliances) should be set aside for the normal working time of the system;
2, the local effective sunshine hours;
3, the local weather data, such as continuous rainy days;
4. The location of the construction system must be open. There must be no tall buildings or other things blocking the sunlight when installing solar arrays;

The conventional configuration of our company's panel components: solar cells are a single power generation device, which is equivalent to a battery with a voltage of about 0.5v; and the panel component is equivalent to a battery with multiple batteries connected in series or in parallel. . The number of solar panel components is usually determined by the system voltage (battery voltage), which is usually 1.4 to 1.5 times the battery voltage. For example: The battery voltage is 12v, the module working voltage is generally between 16.8-18v, then the battery piece quantity is 18v/0.5v, namely is 36 pieces. Therefore, the number of commonly used cells is 36 or 40, and the number of high-power components is 72.
(Note: The specific parameters should be based on local weather conditions and user requirements)

High pole lamp classification

Generally can be divided into lifting and non-lift type. Lifting height of the main pole is generally more than 18 meters, electric lifting operation is convenient, after the lamp pan rose to the working position, it can automatically take off the disc, hanging ditch, wire rope unloading. Elevating mast lamp is provided with manual and electric two lifting control modes, so that the lamp panel can be safely and reliably lowered to 2.5 meters from the ground, which is convenient for maintenance work. The length of the lead wire of the manual remote control device is 10 meters. The operator can remotely control the rise and fall of the lamp panel at 5 meters, so as to ensure the safety of the operator. The elevating mast lamp is also equipped with a spare cable. When the lamp panel is lowered to the lowest position, one end of the cable is inserted into the socket of the electrical control system, and the other end is inserted into the junction box on the lamp panel so that the lamp panel can be directly powered. , repair lamps. All the lamps and lanterns of the lifting pole lamp are sealed to the IP65 international standard to prevent dust and rain from immersing and ensure the service life of the bulb. The material of the lamps and lanterns is generally made of aluminum alloy plate and stainless steel with good corrosion resistance.

High pole lamp lifting principle

In the rectangular cavity at the bottom of the elevating mast lamp, a lifting system such as a motor is installed in addition to the electrical control system. The electric control system is installed inside the lamp pole to avoid the malfunction of the lifting and lowering movement caused by the harsh outdoor environment. Various circuit overload protection devices are provided in the electrical control system. Copper-based silver plating is widely used for the electrical conductors of the circuits in the system to ensure good electrical contact. The elevating mast lamp lifting system drives the lamp pan to move up and down by means of electric motors, (electromagnetic brake) worm gear reducers, safety couplings, main steel ropes, auxiliary steel ropes, rope separators, and moving pulley blocks. The worm gear reducer has a strong self-locking ability, a compact drive, and a large transmission ratio. In order to reduce the gear ratio of the worm gear and the worm, the rise torque is reduced, and a set of moving pulleys is added, so that the speed of the lamp pan is less than 0.2 m/s. . The main steel wire rope is connected with the lamp pan deputy steel wire rope through the rope separator, so as to avoid the winding of the auxiliary steel wire due to the stretching of the main steel wire. The main and auxiliary steel wire ropes are made of high-strength corrosion-resistant 6*19 non-rotating galvanized steel wire ropes. Lifting pulleys are all made of hot-dip galvanized A3 steel brackets, stainless steel shafts, and copper pulleys to ensure that they do not rust and run smoothly under normal atmospheric conditions. Various fasteners washers, collars and other parts are also used hot dip galvanized or stainless steel. There are 6 sets of guide pulley blocks and more than 3 sets of braking devices on the lamp pan. The guide rollers with a 120-degree distribution during the lifting or lowering of the lamp pan roll along the surface of the lamp post to ensure that the lamp pan does not oscillate. The surface of the working part of the guide wheel of the lamp pan in contact with the surface of the lamp stem adopts a rubber heat pressing process. In order to fully ensure that the lamp panel automatically stops when it reaches the limit position, the lamp pans are equipped with reliable limit switches for rising and falling motions and are equipped with over travel protection. The lifting of the high-pole lamp panel is achieved by changing the direction of rotation of the motor. For security and security, the rectangular cavity is equipped with a sealed door and a special door lock is mounted on the sealed door.
