Basic Applications of Lighting | Office Lighting
Office is the space for people to conduct office business activities. Good office lighting not only enhances work efficiency, but also protects the visual health of employees and creates a comfortable office environment. Therefore, how to create a more suitable office lighting environment is an important topic.
1-Lighting Requirements
Office contains more types of functional space. The color temperature (CCT) of general workspace is recommended between 3500 ~ 4000K. If the conditions allow, lighting products or control equipment with CCT changeable function can be used. The CCT can be adjustable according to the law of change of natural light of the day, in order to achieve a more comfortable light environment. Front desk, leisure reception, display space, color temperature range is recommended between 3000 ~ 4000K.
The average illumination distribution of office space, according to a variety of functional attributes of office space requirements, there is normally 500lx for the working space, while it is 300lx for the meeting area. The reception and leisure space and other areas is around 150~200lx due to less restrictive in this area.
Due to the gradual transformation of the current office space to functional complexity and diversity of needs, it is recommended that the lighting control equipment can be combined with the set of adjustable color temperature and illuminance of the lighting system to meet a variety of needs.
2-Public Area
Office space according to the type of space is divided into public area (foyer, reception, marquee, corridors), office area (independent office, open office), conference area (small meeting rooms, video conference rooms, lecture halls), leisure and hospitality area (pantry, lounge, reception) and archives and other types of space.
The reception area is the main space for guiding the flow of people and displaying the company image, and part of it will be combined with the staircase, elevator vestibule and other areas. The average illuminance of this area is recommended to 200lx and white light color or colorful light color can be applied, arranged the lighting comparison with low illuminance and high brightness.
As an important area of communication with foreign visitors, we should meet the basic lighting illuminance on the reception desk. The background wall beside is the most expressive place to exhibit the company image and features. Spot light, wall washer, linear indirect light and so on will be the good solution to emphasize the wall. Moreover, accent lighting can be used and focus on the LOGO. Or we can use the LOGO with backlight and self-illumination, as well as LOGO project light. The average illuminance of the front desk working surface is generally 300Ix, and the color temperature is recommended to be in the range of 3500~4000K.
Corridors can be combined with the ceiling structure, using linear strip or LED PCB installed in the recessed aluminum profile to achieve a good effect, but also to create a soft overall ambient light.
3-Office Area
Office area is the main place for people to carry out office business activities, the environment of this space requires high comfort for visual, and should take into account the physical and mental health of users, good emotional experience and work efficiency.
The average illuminance of the regular working surface of the office space is recommended to be 500lx, the average illuminance of the floor is 150lx, and the average illuminance of the wall is recommended to be not less than 50lx.
The color temperature is recommended to be between 3500~4000K. In addition, further consideration can be given to the needs of the human biological clock rhythm and the use of adjustable color temperature and dimmable lighting fixtures and related control equipment.
The lighting in the office area is divided into the following types according to the way of light output.
A. The lighting design of open-plan office is based on the principle of uniform arrangement to meet the uniformity and comfort of space illumination.
Lamp size is generally designed by the grille ceiling module suitable for grille ceiling or plasterboard ceiling. The use of recessed, surface-mounted or suspended linear downlighting should be seamlessly connected to make it more concise, more complied with the modern architectural style. Luminaires can also be surface-mounted or grille linear luminaires. Surface-mounted luminaires can better diffuse light to make the indoor light environment softer and more comfortable, while the grille light are more effective in reducing glare, according to the actual needs of the use of the appropriate type.
B. According to the location of the seating area to arrange the lighting, is the most commonly used layout techniques, focusing to meet the desktop illumination and comfort. Pendant light fixtures with up and down lighting can be used which can fully improve the spatial sense of the entire office area. Not only in the work surface to provide sufficient light, but also through the illumination of the walls and ceilings to create a better ambient light.
C. For the passageway of the seating area, downlights, wall washers, linear strips or profile can be considered to create the atmosphere of this area, and the average illuminance on the floor is recommended to be around 150lx. The wall area has a positive influence on the brightness contrast in the room. Higher background brightness can reduce the brightness contrast of the computer screen and the luminous surface of the lamps at the same time, which can greatly improve people's comfort, and the average illuminance of the wall is recommended to be around 50lx.
D. For independent office or small independent office, we can use downlights or grille lamps to provide general lighting, and pendant lamps alone to provide desktop functional lighting. The large office can be arranged using zoning to distinguish between different areas, basic lighting and then with desktop accent lighting, so that the entire space to create a different level of space.
Sun light is the most beneficial light for human activities. Office lighting can be combined with the curtain wall shading system design, according to the daily changes in sun light to open or partially open, in order to maximize the use of sun light.
In addition, according to the distance between the window and the indoor desk, we can use dimmable lightings and divide them into different circuits. According to the changes in the outdoor sun light, we can control the brightness or ON/OFF of the lighting to meet the optimal light environment in the office at the same time to achieve energy-saving effect. We can also use the illumination sensor to keep the same illumination.
4-Conference Room
Conference rooms are mainly for face-to-face communication and discussion and reporting. Regular meeting communication should meet the requirements of desktop illumination, while ensuring that the face is clearly visible, avoiding shadows and too large a contrast of illumination. The illuminance of the meeting room is recommended to be 300lx for the desktop, 150lx for the floor, and 50lx for the visual height of the wall.
In addition, another common activity in the conference room is program reporting and communication, projection or TV-based. Lighting should consider the distribution of lamps and the circuit. A separate circuit control should be used near the screen and lighting can be turned off in this area when in reporting. Desktop lighting is recommended to provide dimming function, in the projection program to provide the listener with the most basic writing record function, but also not too bright because of the light environment and affect the effect of the projection.
Nowadays, more and more companies use remote video communication, video conference room with TV, projection and LED screen as the main visual surface, as well as camera. Lighting design should mainly consider the basic requirements and uniformity, increase human recognition and conducive to the camera to capture the characters. But face shadows should be avoid to affect the quality of communication. Live video space illumination requirements will be relatively higher, the illumination in the 750lx or so.
In conference room, we can use surface-mounted or suspended linear fixtures, recessed downlights, surface-mounted panel light or soft film light as the main light of the desktop, surrounded by downlights, indirect light profile, etc. as auxiliary lighting for the passageways and walls.
In addition, it is recommended that conference rooms use dimmable light and set up a lighting control system to adapt to the different needs of use. If conditions permit, it is recommended that the lamps have the function of color temperature adjustment.
5-Leisure reception area
Leisure reception area refers to the office space for people to rest, communicate and negotiate, including leisure function of the pantry, lounge, reception room, etc.
Lighting design should provide a relaxing, cozy light environment. Lightings can be used in the form of diffuse reflection or indirect light, making the overall space light environment softer and more relaxed, and at the same time, consider setting up decorative lamps to increase visual comfort. The illuminance of this area should not be too high, the average illuminance of the ground is about 150lx, and the color temperature can be lower than that of the office area, which can be chosen between 3000~4000K. Lighting design in this area is relatively flexible, color lights can be applied in some area.
6-Intelligent Lighting Control System
With the development of intelligent systems and intelligent drivers, intelligent lighting control is increasingly used in office lighting. General intelligent control has the following functions:
Automatic dimming system adjusts artificial lighting according to natural light changes
Motion detection realizes automatic light shut-off in unoccupied areas
Sub-area control to meet different time periods and functional areas
Scene preset one-key switching different lighting modes
