  • Lighting analysis and requirements for each component of the parking lot.

     

    1. Entrance and exit

     

    The entrance and exit of the parking lot need to check the documents, charge, identify the driver’s face, and facilitate the communication between the staff and the driver; the railing, the facilities on both sides of the entrance and exit, and the ground must provide corresponding lighting to ensure the safety of the driver’s driving, therefore, the lighting here should be properly strengthened and provide targeted lighting for these operations. GB 50582-2010 stipulates that the parking lot The illumination at the entrance and toll should not be less than 50lx.

  • 3. The body of the parking space

     

    The illumination requirements at the parking space, to ensure that the ground markings, ground car lock, isolation rails are clearly shown to ensure that the driver will not hit the ground obstacles due to insufficient illumination when driving into the parking space. Vehicle parking in place after the body needs to be displayed through the appropriate lighting, in order to facilitate the identification of other drivers and vehicle access.

  • 4.Pedestrian route

    Pedestrians pick up or get off the car, there will be a section of walking road, this section of the road should be considered according to the ordinary pedestrian road lighting, provide appropriate ground lighting and vertical surface lighting. This car park pedestrian route and the carriageway have mixed use, according to the carriageway standard consideration.

  • 5. Environmental interference

     

    For safety reasons and directional needs, the parking lot environment should have some lighting. However, the impact on the off-site environment should be reduced, after all, vehicles or parking lots are not aesthetic decorations in the public environment, and they may destroy the harmony of the environment. The above problems can be improved through the arrangement of lamps and lanterns, and an array can be formed around the parking lot by setting continuous light poles, which can play the role of a sight barrier and make the parking lot achieve an isolation effect inside and outside.

  • Lighting Quality Requirements

     

    For the parking lot lighting in addition to the basic illumination requirements, such as the uniformity of illumination; light source color rendering, color temperature requirements; glare is also an important indicator to measure the quality of lighting. High quality site lighting can create a relaxed and good visual environment for drivers and pedestrians.

  • Illumination standards: With reference to the current national specification “Outdoor Workplace Lighting Design Standards” GB 50582-2010, and “Urban Road Lighting Design Standards” CJJ 45-2015, the relevant standards have relevant requirements for various types of outdoor parking lot illumination indicators. CJJ 45-2015 stipulates: “According to the classification of traffic volume, the average horizontal illuminance Eh, av (lx) maintenance value of 20lx, illuminance uniformity needs to reach more than 0.25 “.

    page-16

    For the entrance of the parking lot and the charging place, the “outdoor work site lighting design standard” GB 50582-2010 stipulates that “the illuminance of the entrance of the parking lot and the charging place should not be lower than 50lx.”

    The parking lot adopts the Ⅰ illuminance standard of GB 50582-2010, and the horizontal illuminance standard value is 30lx.

  • The lighting standards for public parking lots are in accordance with the following table:

     

    Traffic Volume Average horizontal illuminationEh, av(lx),Maintenance Value Illumination uniformity maintenance value
    Low 5 0.25
    Medium 10 0.25
    High 20 0.25

    Note:

    1.Low traffic volume means in or around residential areas; high traffic volume means around general stores, hotels, office buildings, etc.; high traffic volume means around downtown areas, commercial center areas, large public buildings and sports and entertainment facilities, etc.

    2.The lighting at the entrance and exit of the parking lot should be strengthened, and it is appropriate to provide lighting for traffic signs and markings, and should be connected to the lighting of the connected roads.

II The way to lay lights

Implementation

 

Light Distribution Method

 

Reasonable lighting design is very important to improve the uniformity of illumination, three-dimensional sense, reduce glare and meet the lighting requirements. The lighting effect of the parking lot is very different with different lighting methods. At present, many domestic parking lots use high pole light or semi-high pole light lighting, with few lamps and lanterns, the more prominent problem of such parking lots is that the uniformity of lighting in the whole parking lot is poor, and when there are more vehicles parked, it will form a shading shadow and aggravate its unevenness. In contrast to this is the use of ordinary street lamp poles, lamps and lanterns arranged in more points (relative to the former). Investigation found that such a way to lay lights through a reasonable distribution of lamps and lanterns and targeted consideration of the choice of lamps, in achieving the same illumination as the former, the latter’s illumination uniformity is significantly better, so the site is more convenient to use, people reflect better.

  • Therefore, combined with the above analysis of the current situation and the layout characteristics of the parking lot, the parking lot design uses a low height of single-headed street lights, semi-truncated lamps and lanterns, arranged in columns at the boundary of the site, the lamps and lanterns are arranged in more points to improve the uniformity of illumination, while reducing the parking lot on the surrounding roads and buildings caused by light interference. Specific lamp layout: lamp installation height of 8 meters, street lamp pole floor mounted form, in the two sides of the parking space on the outside of the bilateral symmetrical arrangement (road width of 14 meters), spacing of 25 meters. The luminaire installation power is 126 W. The distance between the luminaires at the entrances and exits is suitably narrowed to improve the illumination level.

Lamp Selection

 

HID lights and LED lights are commonly used to choose, LED is a solid-state light source, with a small size, fast response, can be modular combination, the power size can be adjusted at will, DC power supply drive characteristics, for the manufacture of lamps and lanterns to bring great convenience. And in recent years in the government’s support and promotion of the development of the speed is very fast, the price of light sources to reduce faster, to create good conditions for LED applications. And taking into account the requirements of safety, security, feature recognition, checking documents, environmental atmosphere, etc., LED lamps and lanterns are selected in this design. Specific lamp parameters are as follows: lamp light rate of 85% or more, LED lamps and lanterns power factor of 0.95 or more, LED overall luminous efficiency of 100lm / W or more, lamp power efficiency ≥ 85%, LED lamps and lanterns color temperature of 4000K ~ 4500K, color rendering coefficient Ra ≥ 70. service life of 30000 hours or more, lamps and lanterns protection level of IP65 or more. Protection against electric shock category is Ⅰ. Based on the above parameters. LG S13400T29BA CE_LG LED Street Light 126W 4000K Type II luminaire produced by LG is selected for this design.

1. Lighting control mode

Light control and time control are set separately, and manual control switch is set at the same time to adapt to different operation requirements. In the light control mode, the lights are turned off when the natural illumination level reaches 30lx, and turned on when the natural illumination level drops to 80%~50% of 30lx. In time-control mode, use the warp clock controller to control, and reasonably determine the time of switching on and off lights according to the geographical location and seasonal changes.

2. Illuminance calculation value.

 

3. Using DIALux illuminance software to simulate the above design content to calculate the illuminance results as shown in Figure 2 (unit: Lux).

Average illuminance [lx]: 31; minimum illuminance [lx]: 25; maximum illuminance [lx]: 36.

Minimum illuminance / average illuminance: 0.812.

Minimum illuminance / maximum illuminance: 0.703.

It can be seen that the above design layout can well meet the standard requirements (average illuminance: 31lx﹥30lx, horizontal illuminance uniformity 0.812>0.25), and has good illuminance uniformity.
