The trend of office lighting

It is estimated that several major lighting manufacturers in Europe have seen the blood spurting, the design of the cloud, the benevolent see the wise and see the wisdom, we will not say. However, what is “trend discovery” and “basic comfort”? The office "improving work efficiency" depends on God Ma, do you make it? Lighting energy-saving benefits are not Asian manufacturers, payback calculation cycle is short, because the price is cheap, you make it?

The research and attainments of European lighting manufacturers in lighting technology, lighting physiology and psychology, lighting applications should be nothing. Let's choose a piece of PHILIPS many years ago (at that time, T5 is still a new light source), to see the trend of office lighting design in the eyes of others, and then look at our "macro theory", hehe. In this area, there are many European brands, Zumtobel and THORN.

Philips Lighting has developed a simple office model that can be clearly categorized according to the functions of the office. This mode allows for a clear definition of lighting and lighting hardware to meet the requirements of different companies. The five office functions defined in the model are multi-person rooms, single rooms, clubs, conference rooms and lounges.

Lighting specific office areas

meeting room

Because the facial expressions of everyone in the group meeting are clearly visible, diffuse lighting is used. When the meeting needs to concentrate on reading, the light should be concentrated on the desktop.

Single room

Ordinary single rooms only require regular lighting, and for more advanced administrative offices, three modes of lighting (ie conventional lighting and function, ambient lighting) are required. The flexibility, aesthetics and personal preferences/controls used are also important factors to consider. The lighting system of the more advanced single rooms includes conventional lighting, suspended functional lighting and accent lighting to create an elegant environment that is consistent with the style of the office interior.

Multi-person room

Uniform lighting is required in multiple rooms to ensure the flexibility of the placement and table and chair placement. The use of low-brightness luminaires avoids the effects of light reflections and daylight on the computer screen. Indirect lighting can be used in conjunction with the daylight control system.

club

It is possible to perform uniform general lighting on the club, which is similar to lighting in multiple people. However, in order to reflect the concept of the club through a dedicated work room, a separate lighting system can be used. For example, the work space and space need to be illuminated, and then use the building lighting to focus on the lighting to provide a comfortable visual environment to create a brighter, higher and larger space.

lounge

The lounge is a place to relax. Lighting in such areas can help create a comfortable environment. With the lighting control system, different atmospheres can be created at different times of the day.

What is lighting technology?

Four key factors affecting future lighting technologies:

flexibility

Modular

Aesthetic and practical

Environmental protection

The luminaire technology has undergone reform in ten years, and energy conservation and miniaturization of lamps have been paid more and more attention. In addition, the color rendering (Ra) and color temperature (Tc) that affect the color effect have also received much attention; Good or bad directly affects people's feelings, and it is also a part of lighting technology.

The new generation of environmentally-friendly lamps that replace traditional fluorescent lamps contain only a small amount of mercury; the T5 fluorescent tubes are thin tubes with a clear diameter of 16 mm, which not only reduces the ceiling area but also reduces the amount of raw materials used. (This paragraph can prove that time is long, haha)

Create your favorite lighting environment

Providing a personalized lighting solution to users is a big challenge. The most advanced lighting control system is equivalent to a building management system, allowing users to choose their own lighting and create a personalized lighting environment. This is achieved by using powerful lighting control including electronic ballast, remote control receiver, controller and other electronic integration capabilities!

Light and health

The earliest and most famous research on lighting is the relationship between lighting, productivity, error rate and fatigue.

As far as we know, the calculation unit for lighting is Lux.

That is, the illuminance, the average person is less able to feel this abstract unit. The sun at noon is about 10,000 lux, and the visual effect is good. The feeling of fatigue and error is 2000 lux. If you think about energy saving and glare, you usually don't use such high illumination, and the 500 lux is more suitable for illumination in long-term work environments such as offices.

After decades of investing in medicine and physical and psychological research and development of human beings, it is found that human daily, monthly, and quarterly activities work with light and dark rhythm; the earth rotates every 24 hours, and the moon is missing. And the earth's revolution to the sun, this will affect all the creatures on the earth, where our biological clock is activated, let us sleep or wake up when time comes, feel comfortable and energetic, and affect the rhythm of our daily life. Have:

mood

Sleep hormones secreted by body temperature pineal glands

Growth hormone secreted by the pituitary gland

Adrenalin-derived stress hormone

Excretion

Sleep/wake mechanism, etc.;

For a daytime office worker, lack of light will strengthen melatonin secretion, thereby disrupting the physiological clock of the office workers, leaving their body and mind at rest, but in fact, the body and mind need to be awake when going to work. This is like the time difference phenomenon will result in lower work efficiency and response sensitivity, which will then affect the quality of sleep and thus damage health.

Conversely, proper exposure to natural light can make the physiological clock function properly and directly stimulate the senses and feel healthier.

The study found that daytime high illumination has a positive effect on people's sensitivity, performance, vitality, vitality index and mood; especially in the long night season when daylight hours are shorter.

As the brain is stimulated by light, it may regulate melatonin secretion and affect the sleep/wake mechanism. This mechanism can be used during day shifts and shifts. Let him accept 3000 at a certain time -

5000 lux illumination of daylight or artificial lighting to achieve the goal.

For nocturnal action, melatonin will be suppressed by the low-illumination light of several lux; but for humans, 1000 lux illumination is enough to prevent falling asleep! However, for cost and power saving considerations, we do not use 1000 lux illumination in the office area, so we only provide short-term lux illumination in some specific office areas to quickly adjust the work pace.

However, research in this area is not enough, and it needs to be further explored before the development of lighting standards that conform to human senses. The world of office has also undergone rapid changes due to a variety of factors. In particular, the Internet has had a huge impact on the way we work, and this has brought about changes in the company's operational structure. Part-time, teleworking and more flexible work have an impact on interior design and work space arrangements. The office concept that is unique to a company depends to a large extent on the type of company, the degree of independence of the employee (either alone or as part of a group), the degree of independence of the department, and the importance and influence of internal and external communication. Last but not least, office workers themselves need to find a relaxed and enjoyable work environment.
