How to design street lighting

Lead viewpoint >>


Road lighting design and lighting requirements should be based on the characteristics of roads and streets, there are general lighting and pole lighting available. General lighting arrangement can be divided into unilateral arrangement, bilateral staggered arrangement, bilaterally symmetrical arrangement, the central and lateral suspension disposed symmetrically arranged (Figure 1.1). When using conventional lighting methods, how to choose the width and lighting requirements should be based on road cross section form , and shall meet the following requirements.


Figure 1.1 are five basic conventional lighting arrangement for conventional lighting arrangement : (a) unilateral arrangement ; (b) bilateral staggered ; (c )  bilaterally symmetrical arrangement ; (d) symmetrically lamp arranged; (e) lateral suspension lamps arranged


The cantilevered length should not exceed 1/4 of the height of the installation, the lighting elevation should not exceed 15 °; 2 the installation height and spacing can be calculated by determining the table 5.1.2. Table 5.1.2 Relationship with light type lighting fixtures with light type ,, mounting height arranged side arrangement and installation of lighting and lighting-height mounting height type and luminaire spacing ,,


relationship between streetlight layout and lighting installation height and spacing

For pole lighting system, lighting and configuration, mounting position, height, spacing, and maximum intensity projection lamp direction shall meet the following requirements:

1.three kinds of lighting configuration including horizontal symmetry, radially symmetric and asymmetric selected according to the different conditions. Those disposed in the wide roads and large areas surrounding the venue should adopt horizontal symmetry pole configuration; others disposed in the interior space or lanes with compact layout should adopt radially symmetric; arranged in a large multi-interchange or lane interchange with scattered layout should adopt asymmetric configurations. Whatever the lighting configuration to take, pole spacing and pole height ratio shall be calculated according to the photometric parameters determined by the lamp;


Figure: pole lighting configuration mode (a) horizontal symmetry; (b) radial symmetry;  (c) asymmetric 

2.poles shall not be located in hazardous locations or wherever Seriously hinder traffic ; angle between maximum intensity projection direction and vertical direction shall not more than 65 °; pole

3.the urban poles light should be harmony with the environment under the premise of.meeting the functional requirements of the lighting.

Take Lead Lighting's LED street light 120W for example


LEAD street lights  has the following unique characteristics:

1. Clock Control:Lighting up for six hours, when there is not heavy traffic in midnight, automatically switching to power-saving mode.

2. Automatic Light Control:When the brightness reaches a value, the LED street lights automatically turn off the light-sensitive photo receptor; When nightfall, and the light sensor automatically lights up the LED street lights; automatically turn on and off, it can be fully realized unmanned automatic management mode. (This function is optional, can be set according to customer demand)

3. Over-temperature protection: The power of LED street lights will automatically temporarily cut off the current in summer when the temperature pass what the LED street lamps can withstand or there is a roaring in lamp temperature to avoid overheating and affect the lifespan of the LED.

 4. Over voltage protection:Power lines can make voltage unstable caused by lighting strikes and other certain circumstances, if the voltage surpass the max voltage the LED street lamp can withstand, the power supply system will be temporarily shut down automatically, which can effectively prevent the lights from being damage, when the grid switch to normal power, LED street light will automatically resume normal operation.
