The selection of lighting for underground garages needs to take into account a number of factors to ensure adequate lighting, ensure the safety of motorists and pedestrians, while taking into account energy saving, environmental protection and ease of maintenance. Here are some specific suggestions, expressed and summarized in a clear structure:

Lighting intensity:
The lighting intensity of the underground garage needs to be bright enough to ensure that pedestrians and drivers can clearly see their surroundings.
Driveways in garages should provide at least 150-200 lux of lighting intensity, while pedestrian areas can be slightly lower.
Light source Type:
If there is natural light exposure, cold light sources can be used to supplement the lack of light at night.
If only artificial light irradiation, you can choose a warm color light source to enhance the visual effect.
It is recommended to use low-energy, high-efficiency electronic light sources, such as LED lights, to reduce energy waste.
Durability of lamps:
The underground garage lighting environment is special, the change of temperature and humidity is large, and the dust is more, so the durability of the lamps is very important.
It is recommended to use waterproof, dustproof, corrosion-resistant lamps, such as LED lamps and so on.
The selection of lamps with high quality materials can greatly increase their service life and reduce maintenance costs.
Uniformity:
Lighting should be evenly distributed throughout the garage area to avoid differences in light intensity to reduce visual discomfort.
According to the layout and structure of the garage, the installation position of the lamps is reasonably designed to ensure that the lighting can cover all corners, while avoiding shadow areas.
Color temperature CRI:
Choosing the right color temperature with a high color reduction index (CRI) can improve visual comfort and safety.
In general, choosing a neutral color temperature (about 4000-5000K) and a higher CRI (greater than 80) can guarantee a better visual effect for the human eye inside the garage.
Avoid glare:
Avoid using too strong direct light sources, so as not to cause glare problems for drivers and pedestrians.
The use of anti-glare design, lamp shades or shielding panels can effectively reduce glare.
Emergency lighting:
The underground garage needs to be equipped with emergency lighting to prevent safety problems in the event of an emergency or power failure.
Emergency lighting needs to meet regulatory requirements and be able to provide adequate lighting in the event of a power outage.
Energy efficiency and conservation:
Choosing energy-efficient LED lights, combined with light sensing or motion sensors, can reduce lighting intensity and save energy when the garage is not in use.
Lighting control:
Taking into account the different time periods used by the garage, the appropriate lighting control system can be set up to adjust the lighting intensity and mode according to the needs.
Maintenance convenience:
The installation and maintenance of lamps should be convenient, so that the damaged lamps can be replaced in time to ensure the continuous lighting effect.
To sum up, the selection of lighting for underground garages needs to consider multiple factors such as lighting intensity, light source type, durability, uniformity, color temperature CRI, glare avoidance, emergency lighting, energy efficiency and energy saving, lighting control and maintenance convenience. Through reasonable selection and design, the safety, comfort and energy saving of the underground garage can be ensured.
