Parking Lot LED Energy-saving Lighting Solution

1.Proposal background

The parking lot is the place for parking vehicles in the city. At present, the population of Hainan city is increasing rapidly, and the number of motor vehicles is increasing rapidly. Driving shopping has become the fashion of car owners. Therefore, supermarket parking lots are increasingly developing to underground garages. But the lighting energy consumption of parking lot is the main component of the operating cost of the whole underground parking lot. How to effectively solve this problem has become a public problem of parking lot. The HBN-300 intelligent floodlight system effectively solves this problem and achieves intelligent control and on-demand lighting scheme.

Traditional lighting control parking lot mainly uses energy-saving lamps to reduce energy consumption or only light up a part of the energy-saving lights. However, this lighting effect can not meet the requirements of cecs45:92 and jgj100-98, and this lighting control can not achieve energy-saving light source, only reduce energy consumption in the process of use, and do not achieve the maximum energy-saving effect – only use it when necessary.

A small number of parking lots adopt intelligent lighting control system, which can achieve the effect of regional control and timing control, but there are many problems in the complexity of operation and incompatibility with the security system. How to achieve both energy saving and effective management is one of the problems faced by many management parking lots.

It is suggested that the signal line and power line should be laid separately.

3.5 garage entrance lighting

According to the actual situation and needs of ShangBang Baihui city parking lot, the intelligent lighting scheme for the parking lot is formulated. The main contents are as follows:

T8 fluorescent lamp is used in traditional garage entrance and exit passage lighting, which has short service life and strong glare. Because of the phenomenon of “adaptive lag” in the right eye. In order to overcome this situation, Tachyon puts forward the intelligent lighting technology of “light handshake” for channel lighting, which effectively makes up for the phenomenon of “adaptive lag” due to the right eye hole.

3.6 functions and features of LED lighting at the entrance and exit of parking lot:

3.6.1. High power, high brightness, low power consumption and high luminous efficiency.

3.6.2. Intelligent automatic control of lighting on demand is adopted.

3.6.3. Long service life, not easy to damage, basically no need to replace again.

3.6.4. The internal structure is highly integrated and easy to install and transform.

3.6.5. Led anti glare lampshade is adopted to make the light softer and no glare.

3.6.6. It has two modes: power saving mode and constant lighting mode, which can be adjusted automatically according to personnel or vehicles.

More than 85% power saving rate can be obtained by using coding high-power LED lighting. Moreover, semiconductor lighting itself is a green light source with low energy consumption, and its high efficiency will bring about the power saving rate at the facility level; in addition, the power consumption mode of “lighting on demand” will also bring about power saving at the working system level.

3.7 two lighting states of the lamp:

Highlight state: the maximum brightness power is 32 watts. In this state, the intensity of illumination can be adjusted in the management and control software (high, medium and low lighting luminosity, which meets the requirements of GB 50034-2004 building lighting design code).

Power saving mode: in this state, the power is maintained at 2 watts, which can meet the minimum brightness required for safety on site (the brightness can be set in the management and control software according to the needs of the site).

 

3.8 illumination standard for interior lighting of parking lot:

Illumination standard

The standard value of lighting design illumination for underground parking lot formulated according to cecs45:92 (Table 1 below)

category	Reference plane	Lighting standard value (LX)
		Low	Med	High
Vehicle Lane	Ground	30	50	75
Parking space	Ground	20	30	50

According to the code for design of garage buildings (jgj100-98), the lighting standards for garages are as follows: (Table 2)

category	Reference plane	Lighting standard value (LX)
		Low	Med	High
Vehicle Lane	Ground	20	25	30
Parking space	Ground	10	15	20

It can be seen from table 1 and table 2 that the difference between lane and parking space ground lighting is about 50%. Therefore, the intelligent garage access lamp HBN-60 (60W) is installed above the garage passage to effectively solve the lighting problem of traditional parking lot.

In order to reduce the glare when driving and consider the role of guiding driving, the long axis of the lane should be consistent with the driving direction of the vehicle, and the configuration of lamps and lanterns should correspond with the lane and be arranged in order, so that the lighting guidance is good. On the contrary, if the distance is too large or the arrangement is irregular, the driver can not correctly predict the alignment and direction of the road ahead, which is likely to cause insecurity and cause lighting The guiding ability is poor. The parking direction (i.e. the direction of the long axis of the vehicle body) is generally perpendicular to the driving direction. Considering the uniformity of the lighting in the parking area, the long axis of the parking light should be perpendicular to the long axis of the vehicle body. When a car body is 4.7 m * 1.7 m, and each parking space area is considered as 16 m2, a 32W intelligent LED lamp is installed according to the illumination brightness value and 50lx illumination value standard.

When there is a car or a person in and out, the infrared sensor in the corresponding area receives the infrared wavelength, and the power saving mode is awakened and turned on, with the power of 60W, which is convenient for vehicles or people to pass. When the car or person leaves the sensing area for about 30 seconds (the highlight time can be adjusted according to different places), the LED lamp will automatically re-enter the power saving mode with the power of 2W.

The infrared sensor is used to control each LED lamp in the parking lot. When there is no vehicle going in and out, all the lamps are in the power saving mode, and each lamp consumes 2W, which not only meets the requirements of security monitoring lighting, but also saves power to a great extent.

4. Benefit analysis

The modern lighting idea of “intelligent control and lighting on demand” proposed by our company breaks the traditional grouping control scheme. Tachyon handshake lighting system has made great breakthrough in intelligent system application and lighting technology. It not only has the nature of substitution and Transcendence in function, but also has strong competitive advantage in economic benefits.

4.1. Energy saving benefit analysis:

The cost of lighting system of the project is $16412, and that of guiding system is $21441.

The total cost of the project: $16412 + $21441 = $37853

The total investment payback period of the project is: $37853 ／ 40419.68 = 6.4 years (excluding the operation cost of traditional parking lot, but the system can obviously save labor cost and working time.)

4.1.1. The power consumption of traditional public lighting is about 48000 kwh per year

4.1.2. Annual power consumption of bv-led project: 7580.32 kWh (if necessary, intelligent software can be used to manage and close part of it, which will save more power.)

4.1.3. Annual cost saving: $5944 (in consideration of the increasing commercial electricity price year by year, the 20-year dynamic electricity is adopted here price weighted average $0.2 / kWh)

4.1.4. Investment payback period of intelligent lighting: 109800 × 40419.68 = 2.7 (years)

4.1.5. Based on the 20-year service life of the system, the total power consumption can be saved: $132907.30

$5944 × 20 years = $118881.41
