How do solar street lamps light pole height and spacing design

 road motor vehicle traffic and the pedestrian average illuminance is city road lighting one of the evaluation index, and street lamp configuration of an important reference index. A city road to configure or replacement for the LED street lamp' LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 First, technology will be involved in related index of the lighting calculation. With 'utilization coefficient Utilization factor is a face or other provisions of the reference plane, the luminous flux directly or by reflection to accept each other with the launch of the rated all lighting lamps and lanterns of the ratio of the total luminous flux. 】 'One of the method of calculation is more simple and effective method. 'Utilization coefficient method to calculate the formula of' absolute copying the traditional lighting theory research conclusion. We have to do is to some experimental and theoretical data input formula of LED street lamp, get the results, and with the requirements of road lighting design standard reference. It goes without saying that these calculations are LED street lamp design, development, improvement, improvement and marketing of necessity. Utilization coefficient ( U) Is directly on the road of the ratio of luminous flux, luminous flux and all source and the height of the street lamps and lanterns, elevation, arrangement, road width and so on. Luminous flux ( Φ) Is the eye of the lighting source and being received the sum of energy. Time how much radiation of light energy of said unit, the unit for lumen 【 The so-called lumens, describes the physical unit of luminous flux, physical explanation for a candle, CD, Candela Candela, unit of luminous intensity, luminous intensity is equivalent to a normal candle) In a solid Angle, Radius of 1 m on the unit sphere of 1 square meter of ball crown of the cone Angle, represented the central Angle of the corresponding section of 65 °) On the total emission of luminous flux. 】 lm。 Other representation: CD. sr( The CD is the unit of luminous intensity: candela 【 Candela ( Vincent Candela） , born on October 24, 1973, it is France's professional soccer player, defender. 】 。 The Sr is solid Angle steradian unit. Intensity of illumination, E) Is luminous flux and coefficient of the ratio between the exposure area, unit for lux lx. Lx namely 1 lm luminous flux of average energy distribution in the area of 1 square meters, the lm/m2. (the average illuminance on the road 由【 Chemical product name: ethylene - Vinyl acetate copolymer chemical English name: ethylene - vinyl acetate copolymer。 】 ） Is in accordance with the relevant regulations on the road pre-set point measured or calculated by the average of the intensity of illumination. Maintenance factor ( k） Is lighting device to use after a period of time, in the average illuminance on the surface or the average brightness with the device in the same conditions when the newly installed on the same surface of the ratio of the average illuminance or average brightness. The installation height of lamps and lanterns, H） The vertical distance is the optical center to the road of lamps and lanterns. The installation of lamps and lanterns spacing ( S） Is along the road centerline measured the distance between the adjacent two lamps and lanterns.
