Recently, I received a lot of calls from dealers, asking how many meters is the height of solar street lamp installation, and I don't know how much should be chosen. LED street lamp it is a kind of efficient solid state light source based on semiconductor PN junction formed with weak electric energy can emit light, in a certain forward bias voltage and injection current, injected into the hole in the P region and injected into the N region of electrons in the diffusion to the active region after radiation compound and emit photons, the electric energy directly into light energy. It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life and other characteristics, therefore, LED street lighting will become the best choice for energy-saving transformation.
The following professional solar street lamp manufacturers xiaobian for you to explain:
How high is suitable for solar street lamp installation? In order to avoid glare, diffuse reflection medium (d)(e)(f) and solar street lamps may be selected and their heights should not be less than 4.5m. The interval between solar road lamp poles can be 25~30m, into the corner of the lamp pole spacing should be appropriately reduced. When the path width is A, the height of the courtyard lamp can be selected according to 0.6A(single-side cloth lamp) to 1.2A(double-side symmetrical cloth lamp), but should not be higher than 3.5m, the distance between the courtyard lamp poles can be 15-20m, the elevation of the solar street lamp on the horizontal line should be 5 degrees, and the road brightness should not be less than 1cd/m2. For outdoor lighting, separate short-circuit maintenance should be set at each lamp post. The ratio of minimum illuminance to maximum illuminance should be between 1:10 and 1:15.
The device height of solar street lamps: axisymmetric light distribution lamps should be adopted for high-pole lighting. The height of lamp device H can be determined by the following method: H≧0.5R.
R is the radius of the illuminated category in m. High pole lighting appropriate to take lifting type lamp plate. A. Planar layout of solar street lamps The planar layout of solar street lamps is limited by many objective premises, and many factors need to be considered, which affect and restrict each other.
Such as the grade of the way, traffic flow, speed, road width, road structure, lamp power, device height and intersection and other premises, the plane layout is different.
Outdoor lighting should be remote controlled in the duty room or substation room, and local lighting can be turned off at night. Three-phase load balancing should be adhered to in different lamp control methods when three-phase power distribution is adopted for outdoor lighting. The placement of light poles in the outdoor parking plaza shall not affect traffic. Parking square lighting can adopt high color rendering and long life light source.
1. Individual way of lamp distribution method (solar street lamp arrangement method). The wiring on the back of the solar panel is reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape. When the width of the path does not exceed 15m, the single-side lighting method is usually adopted.
2. If the cloth lamp of the intersection is a T-junction, it is best to set the lamps and lanterns in the way to do the real opposite, which may effectively illuminate the road, but also conducive to the driver to identify the end of the way.
3. The lamps hanging in the center of the intersection are often covered with red lampshades to attract drivers' attention. The wiring on the back of the solar panel is reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape. In the complex traffic intersection, in order to cause the driver to be careful in advance, in the adjacent sections of the variety of lamps or light sources of the variety (that is, to change the luminous flux of lamps and lanterns) also have good consequences.
Intersection design illuminance standard request higher, individual not less than how many intersection path illuminance standard with. If the illuminance standard of intersection path is relatively large, the driver from bright area into dark area drop is larger, because the person's eyes have "dark adaptation".
To sum up, the height of the solar street lamp can be calculated from the above formula.
