Design specification for LED lighting of underground garage
The lighting in the garage should be evenly distributed to avoid glare, and its spatial illumination standards should meet the regulations.
Emergency lighting should be set up in the car entry and exit passages, personnel evacuation passages, power distribution rooms, and duty rooms in the garage, and the number of lights should be increased at the corners
Sign lights and guide lights should be set up in the garage according to the driving needs. The entrances and exits of the garage should be equipped with signal lights and parking space indicators indicating the entry and exit of cars. Transition lighting shall be provided at the entrance and exit of the ramp-type underground garage.
Its design should meet the requirements of the underground building lighting design standards.
The brightness change at the entrance during the day can be 10:1 to 15:1, and the indoor and outdoor brightness changes at night can be 2:1 to 4:1.
The main entrance and exit and double entrance and exit, depending on the number of garage floors, are in the normal parking space of 4X4 according to the land, but the entrance and exit can be set as a single entrance according to the traffic flow, and one entrance and one exit.
The three-layer can be set to double-out and double-inlet. If the single-layer area is too large, it is designated as one-way, with one entry and one exit. The condition is a multiple of 4X4=16 parking spaces.
1. Reasonably arrange the position of the LED lights
New garage design: LED light source should be used as the light source, and the roadway lamps should be LED light source of about 12W~16W and radar control method, and the color temperature should be about 4000K~4500K.
Lamps should be arranged evenly on the main road in the garage, and the distance between lamps is about 7 meters (determined according to the reflectivity of the ground material).
Due to the low floor height of the underground garage, the light source power of the lamps should not be too large, and the light distribution angle should not be too large. Improve the uniformity of lighting.
A lamp is arranged above the parking space, which is convenient for parking. The lamp should be controlled by an LED light source of about 8W~10W and radar.
At the entrance and exit of the vehicle, the distance between lamps and lanterns can be smaller, the illuminance can be appropriately increased, and there is a visual adaptation process between bright and bright.
The lamps in the open air at the entrance and exit of the vehicle are installed on the wall. The protection level of the lamps should reach IP55 or higher to prevent rainwater from immersing in. The installation height is generally about 30cm from the ground.
Existing garage renovation: The existing garage lighting energy-saving renovation, using LED garage lights, the light source is about 12W~16W.
before replacing the lamps, you must pass the actual investigation on the site to find out the laying method of the original line and the installation method of the lamps, and choose the appropriate one.
Instead of lamps, it is relatively simple to choose a single lamp and single control method for the transformation project, and the distribution lines generally do not need to be transformed.
In the outdoor parking building, since there is no need to turn on the lights during the day, the LED smart garage should increase the brightness automatic control function.
When the brightness in the garage is lower than the specified value, the lighting lamps can be turned on.
2. Light source
The light source of garage lighting should be an LED light source, which is also the most ideal application place for the LED light source.
Condition:
a. easy to control
b. Energy-saving
c. Give full play to the application advantages of LED light sources
D. Improve the cost-effectiveness of LED lighting applications.
Compared with T5 and T8 straight tube fluorescent lamps, the investment recovery period is generally about one year.
The theoretical light efficiency of the white light of light-emitting diodes is more than 3001m/W, and the theoretical life is more than 100,000 hours.
Whether it is in the packaging of chips or the manufacture of lamps, there is a lot of room for innovation and development.
The speed of development is very fast. The reduction is faster, creating good conditions for the application of LED lights.
Garage lighting is currently more appropriate to replace T5 and T8 fluorescent tubes with smart LED lights.
Because the LED light source has strong controllability, power variability, intelligent control, and high-cost performance, the light efficiency is slightly higher than that of the straight tube fluorescent lamp, not only the power saving effect is significant, but also the service life is long, and the maintenance cost is effectively reduced.
It can be seen that the application of LED lights in the garage has its obvious advantages, and it also conforms to its controllability characteristics.
