Lighting system in office building applications

The application of intelligent lighting in the office building is mainly office area, leading office, lobby, multi-function hall, and can also control outdoor, parking lot, public part and so on.

·Functional Requirements

Main station: to meet the regional illumination, you can control the lighting of the entire lobby.
Lobby lighting: Turn on the corresponding lights according to different time periods, save energy as much as possible under the premise of meeting the lighting requirements of each time period, and effectively use the natural light outside the window. (requires dimming)
Office area: reduce the long light, increase management, save energy and save management costs.
Leading Office: It can set office, meeting, negotiation, rest, small meeting mode to improve environmental quality. Lights and curtains can be linked.
The multi-function hall should complete the functions of meeting, training, cocktail party, entertainment, exhibition, etc. The lighting system can adjust the entrance, host, meeting, projection, discussion, rest, and exit to make corresponding lighting changes.
Parking area: To meet the lighting needs of drivers when parking, it is necessary to save energy as much as possible.
Public part: To meet the needs of people and vehicles walking lighting, we must do our best to save energy.

· Use traditional lighting control If you encounter the following problems, it is time for you to choose intelligent lighting system.

The lighting in the lobby is always open to the brightest, no matter how abundant the sun is, I want to save electricity and I am afraid that the staff will forget to turn on the lights when the lights are turned on, causing the lobby to look dark.
The multi-function hall has a large row of dimming switches. When it is necessary to adjust a required scene, the operator needs to adjust one by one according to the table, so that the general meeting does not adjust the lights according to the progress of the meeting.
When you need to play a slide in a meeting or training, it takes a long time to dim the lights, and you may turn off the lights.
The large open office is leased to a small company and it is necessary to re-route the top to meet the requirements.
Large-area offices turn on all the lights even during the day, and no one in the staff considers energy-saving issues, and one person turns on all the lights.
The underground parking lot was turned on 24 hours, so that the property company needed to remove one of the lamps for each double-tube lamp, because the tens of thousands of parking charges in January plagued the property company.
Night duty personnel need to patrol the entire building to turn off all unwanted lights, but sometimes the duty staff are often lazy.
Due to seasonal changes, the outdoor high-power lights use traditional timers to light up when the sky is very dark or to illuminate when the sky is still on. It is not necessary to modify the timer once a week or monthly, and it is troublesome to adjust the timer once. Holidays require someone to adjust the switch light time.
Unlit lamps have not been replaced because they have not been found by property personnel.
Large chandelier bulbs are not easily replaceable but are always susceptible to damage.
More than 30% of the electricity bills for lighting from one hundred thousand to several hundred thousand in a month are wasteful.
Electric shock due to damage to the control panel.

· Advantages of intelligent lighting

In the lobby, multi-purpose hall, office, and leading office, you can set a fixed lighting scene to be linked with the curtains to create a good lighting atmosphere. Switch with one button to avoid misuse.
The natural light is used to assist the illumination, the scene is dimmed, and the person lights up and the lights go out, and the scene is adjusted according to different time periods to achieve the energy saving effect.
The warning of the life of the lamp can record the total opening time of the lamp to remind the user to replace the lamp in time, and can prompt the property personnel to increase the inspection frequency of the circuit to prevent the bad lamp that has reached the service life from being replaced.
It is convenient to expand and transform. By simply modifying the software settings, you can adjust the lighting layout and expansion functions without changing the wiring, reducing the cost of retrofitting and shortening the construction period.
Soft start reduces current to fixtures and power distribution equipment for extended life.
Convenient operation, can focus on the computer graphical interface to monitor all lighting status, centralized management of lighting, without on-site control, remote control, manual control.
Automatically adjust the switch light time according to seasonal changes.
The system is open and can be combined with other property management systems (BMS), building automation systems (BA), security and fire protection systems to meet the development trend of smart buildings.
The lighting scene can be automatically switched at a time to realize unmanned management and improve management level.
Safety, smart switch panel uses 24V DC to prevent electric shock.

· Program

The Chinese monitoring software is installed on the computer of the main station or the monitoring room, and the lighting of any circuit on each floor of the entire office building is monitored and controlled through a graphical interface; the lights are individually switched, grouped, and closed.
The lighting in the lobby is mainly controlled by the combination of light control and timing control to maximize the use of natural light dimming. At night, the timer is used to adjust the illumination of the lobby to the optimal state according to the time of the nighttime personnel activities.
The office area adopts light perception during the day, making full use of the use of sunlight. When the illumination is satisfied, the light is automatically turned off. When the illumination is not enough, the light is automatically turned on to supplement the illumination through the light. As the daylight becomes weaker, the light becomes brighter and complements each other. Every day at work, the light is turned on at regular intervals to adjust the light at any time. When the time is off, the light is turned off at the time to turn on the infrared, so that the person lights up and the lights go out, and the lights are also controlled by the wall switch.
Intelligent scene switches and intelligent switches are installed in the multi-function hall control room to centrally control the multi-function hall lamps. The infrared sensors are installed on the ceiling of the host table, which is convenient for remote control at the host station.
The multi-purpose hall sets up the admission, hosting, meeting, projection, seminar, rest, and exit scenes required for the conference and training, and is controlled by the scene switch and or the remote controller.
When the parking lot has a large traffic during the daytime, all lights are turned on regularly; when the traffic volume is small, 1/2 lamps are turned on; when the night is late, most of the lights are turned off, the basic lamp illumination is retained, and the motion sensing control is used; When someone or a car appears, the lights in the corresponding area are automatically turned on, and when the person or the car leaves, the lights in the corresponding area are automatically turned off.
It can also be linked with the garage system. When a vehicle with a fixed parking space enters the garage, the lights along the line of the owner's parking space can be automatically opened in advance, and the lights automatically recover after the owner leaves.
The public part of the light can be combined with timed and centralized control. It is energy-saving through regular time. When there are important guests or leaders, all lights can be opened at the same time to welcome guests.
The outdoor lighting is automatically adjusted according to the season, the street light is automatically turned on according to the season, the street light is turned on when it is dark, some lights are turned off at 9:00, some lights are turned off at 11:00, and all lights are turned off at dawn; when the holidays and special dates are dark All street lights and decorative lights are turned off as needed (eg 1 am). The above operation is completely automatic and requires no human intervention. When you need to modify, just modify a few data in the central control room.
