Sixth, the application effect of intelligent lighting control system in Sofitel People's Building in Xi'an
1. Realize the intelligent control of lighting After adopting HDL intelligent lighting control system, the lighting system can work in the fully automatic state, the system will switch some basic working states according to the preset, and automatically in various working states according to the preset time. Conversion between. For example, in the morning, the system automatically dims the lights, and the illuminance is automatically adjusted to the most comfortable level of people's vision. In the area near the window, the system intelligently uses the outdoor natural light. When the weather is fine, the indoor light will be automatically dimmed; when the weather is dark, the indoor light will be automatically brightened to maintain the brightness of the indoor setting (according to the preset brightness).
When the night falls, the system will automatically enter the "evening" working state, automatically and extremely lightly brighten the lights in each area.
In addition, the lighting engineer can also use the manual control panel to carefully preset the lighting scene according to different times of the day and different purposes. When using, it only needs to call the preset optimal lighting scene to create a novel visual effect. Feel free to change the illuminance of each area.
2, beautify the service environment to attract guests to visit the good lighting design can attract a large number of customers for the hotel, and can create a warm, comfortable environment, adding to the charm of its art. The customer's first impression of the hotel is the hotel entrance to the lobby reception area. The elegant and chic light environment can give customers a feeling of being at home, adding customers' affection to the hotel, friendly and warm.
The hotel interior includes a banquet hall, VIP bar, and western restaurant. The color, projection and different brightness of the light can create a three-dimensional, layered and different color atmosphere, which not only makes the guest have a comfortable living environment, but also It can create a sense of artistic appreciation and a sense of staying in the hotel.
3, considerable energy-saving effect In addition to providing guests with a comfortable environment, saving energy and reducing operating costs is another important concern for owners. Since the HDL intelligent lighting control system can perform the illuminance setting according to the operation of each functional area according to different dates and different times through reasonable management, it is guaranteed to turn off the lights when no lighting is needed; in most cases, many areas In fact, the HDL system can provide the most comfortable lighting with the most economical energy consumption. The system can ensure that the lamp is only lit when necessary or reaches the required brightness. Greatly reduce the energy consumption of the hotel. 4. Extend the life of the lamp. The fatal cause of the lamp damage is the overvoltage of the power grid. The higher the operating voltage of the luminaire, the more its life is reduced. Conversely, when the operating voltage of the luminaire is lowered, the life span is doubled. Therefore, properly reducing the working voltage of the lamp is an effective way to extend the life of the lamp. The HDL intelligent lighting control system can successfully suppress the surge voltage and surge voltage of the power grid, so that the lamps will not be damaged prematurely for the above reasons. The voltage limit can also be artificially determined by the system to improve the life of the lamp. The HDL intelligent lighting control system uses soft start and soft shut-off technology to avoid the thermal shock of the filament and further extend the life of the lamp.
The HDL Intelligent Lighting Control System successfully extends the life of the luminaire by 2-4 times. It not only saves a lot of lamps, but also greatly reduces the workload of replacing the lamps, effectively reducing the operating cost of the lighting system, and has special significance for lamps and expensive lamps in difficult-to-install areas.
5. Improve management level and reduce maintenance cost HDL intelligent lighting control system converts ordinary lighting artificial opening and closing into intelligent management, which not only enables hotel managers to apply their high-quality management awareness to lighting control system. Going, and at the same time, will greatly reduce the operation and maintenance costs of the hotel, and bring a great return on investment.
