In the early 2020 epidemic, many urban white (SHE) collar (CHU) on the Internet or friends in the circle of the remote office, the office station can be said to be a thousand strange but no dense pleasant comfort .
However, after a week, people have issued the feelings of missing the office. In addition to the interference factors around, the working hours are difficult to fix, so that “996” is “007”, there is also a very important reason – the office environment is poor, Insufficient office conditions, leading to low efficiency, severe back pain, two eyes fainted.
But the problem is coming, is our office environment? How many people have a long office?
Or like this
There is such a
In the end, traditional office space is the same as at home, and it needs to solve 2 problems: First, stay. Second, the efficiency is high. How to achieve these two points through the design of the light environment and the choice of lamps? I’m here today.
What are the key points of modern office lighting?
Select the light source, reasonable configuration
Guaranteed comfort and improve work efficiency
The comfort can focus on three aspects, first is the illuminance ratio.
National standards stipulate that the general office is 300LX, and the high-end office is 500LX. According to the requirements of the brightness distribution, in addition to the operation illuminance, the lighting needs to provide appropriate adaptive brightness to achieve a comfortable office environment.
From the visual perspective, when the lighting is more and more, the time of the lighting is most comfortable when the illumination is close to “1”; it is reversed that the more the ratio is more visual fatigue.
▲ In addition to the work surface, the illuminance of the work surface adjacent the surrounding area (the width of the work surface is not less than 0.5m) can be smaller than the work surface; instead of the operation area (the operating surface is not less than 3m from the surrounding area) It is not appropriate to be lower than the 1/3 source of the surrounding area: Yunzhi Guang Lighting College
Secondly, for the office, this school takes a long time to stay, the color temperature of the lamp should not be too low.
Excessive low will make people sleepy, reduce productivity or learning efficiency; too long is too excited, affecting health. The office is clearly selected to choose a neutral color temperature, about 4000K.
▲ The left picture is too low color temperature: 2700K; the intermediate map is neutral color temperature: 4000K; the right picture is over high color temperature: 6000K
There is also glare. The glare caused by disgusting, visual fatigue, and even loss of bright eyes, so it is extremely important to avoid glare problems in office lighting.
▲ UGR is the quantitative indicator of the uncomfortable glare of indoor lighting, and the national regulations generally use the UGR value of 19 or so, the lower the value, the more comfortable people visual feelings.
Glare is generally divided into
Indirect reflection glare
In the office space, the problem of direct glare can be avoided by increasing the brightness of the surrounding environment or to reduce the brightness of the light source (also simultaneously). In general, the average illuminance of the wall should not be less than 50LX, and the average illumination of the ceiling should not be less than 30LX.
▲ Directive glare refers to the light entered in the normal look (rose red arrow), the green arrow does not cause too strong stimulation for people’s eyes.
On the selection of the luminaire, it is preferable to choose a lamp with low glare or lateral light; it can also be used to avoid glare.
Indirect reflection glare, it will exacerbate glare values when encountering a mirror or black surface material, in which case the light source can reduce reflection glare after being placed on the rear or side of the work surface.
For computer, this vertical work surface can be achieved by “indirect illumination” to achieve a uniform lighting effect, avoid reflection glare, but it is expensive, which is generally used in office lighting.
▲ Individual reflection glare, severe reflection glare affects employees’ work
Create a flexible office space that is integrated with office, exchanges, and rest
According to the characteristics and needs of modern office space, as well as the understanding of the light source, electrical technology and products, the designer is basically established in the framework of the office lighting design.
Modern office space is no longer just a place where employees are independent of work, but more becomes more exchanges, and is a place between employees, employees and customers communicate and communicate information.
Therefore, different functional areas should be made in accordance with the corresponding lighting design. The lighting design and luminaire selection is especially important. Even a good fixture with a strong enough flexibility can meet the needs of people’s different spaces.

This flexibility can be manifested in a free combination, such as whether it can be used to match the linear light strips of different styles to match different spaces; whether there is a variety of installation methods for different types of ceiling Go to select the appropriate installation method; it is also manifested in flexible and convenient power interface, reducing the installation time cost, and so on.
Said so much, what is commonly used in office lighting? How should I choose?
Type of office lighting
In the traditional office lighting, almost all the horizontal world.
The general conventional grille lamp is combined by three 60cm short lamp, or 2 120cm long lamp combination, mounted in a grid light. It can avoid glare, low maintenance cost, but energy consumption, and high frequency.
▲ traditional grill lamp office lighting map
After the LED is popular, the selection is very large. Compared to the traditional grille lamp, the LED has the characteristics of reducing line loss, long life and energy saving and environmental protection. Types from the rear lamp, flat lamp, linear lamp to landing lamp, not enough.
Among them, the LED flat light passes through the high light guiding plates to form a uniform illuminance, and the light is soft. From the lamp design, it is simple atmosphere, with a certain sense of art. Therefore, the LED flat lamp gradually became a hot choice luminaire in the office, supermarket and other places.
Next, we take the ultra-thin LED tablet lamp of Tele, introduce how to buy a good LED flat light.
How to choose a good LED flat lamp?
The LED flat light uses a unique SMD patch as a light source, plus the light guide plate and (or) diffusion plate, causing the LED flat lamp ultra-thin design not only to provide lighting, but also adding artistic beauty.
▲ Special Okimin LED Flatlan Light Series Product Examination
In actual choices, we mainly look at the following:
1, see “power factor”
The power factor of the luminaire is low, and the driving power supply and circuit design used are not good, which will greatly reduce the life of the lamp.
The LED flat lamp is a constant current drive, but does not exclude some of the products use voltage drivers, so that the LED flat light is speeding up.
In this regard, we can use the “power factor table” to detect, and the general export LED flat lamp power factor is required to reach 0.85.
Products that power factors below 0.5 can be said to be unqualified products or garbage products, not only short life, the actual consumption is more than twice more than the nominal.
For example: In the special product, the ultra-thin LED flat lamp series, it uses
SMD high-efficiency chip and LED constant current driver, power factor (PF) ≥ 0.95, color color index (RA) ≥80
Its power factor completely reaches the requirements of the general export LED flat lamp, the actual power consumption is low, energy-saving and environmental protection; its power factor is high, the constant current driver, the light decline can ensure the service life of the lamp to ensure product quality .
2, look “light effect”
The higher the light efficiency, the higher the brightness. At the same lightweight, the smaller the power consumption, the more energy efficient.
For example, the special Mei ultra-thin LED flat lamp is a high-light luminaire, and the light efficiency can reach 100LM / W, which can meet the basic lighting of spaces such as the office, supermarket.
3, watch lights, heat dissipation conditions, materials and structures
If the heat dissipation conditions are not good, the lamp beads work at high temperatures and their life will be greatly reduced.
In general, materials with heat dissipation are mainly copper, aluminum, and PC. Among them, copper thermal conductivity is better than aluminum, and the thermal conductivity of aluminum is better than PC.
At present, radiator materials are generally used in most aluminum, especially inserted aluminum heat dissipation.
High quality LED flat lamp, the lamp body is generally one body, and the use of aluminum alloy antioxidant materials, can be used in any humid environment, avoiding the emergence of rust-leakage, does not affect its use.
Taking special excellent products as an example, its optical treatment material adopts an optical diffusion plate, which makes it soft and achieves a comfortable and pleasant light effect.
It is a one-piece aluminum, which is well dissatted, and the lamp is light. While ensuring that the pressure of the ceiling is reduced, it can avoid the emergence of rust-leakage, power drive failure.

4, look at “Lamp Quality”
The quality of the lamp beads is determined in the chip quality and packaging technology. The quality of the chip determines the brightness and light failure of the lamp beads. Good lamp beads are not only high in light, but also small light decline.
5, see “drive power”
The appearance uses the power supply of aluminum alloy material to drive with the power driver of engineering plastic, the former is good.
The power drive of the aluminum alloy is not only dissipated, but also during the transportation and use of the lamp, the parts inside the lamp can be effectively protected, which can effectively reduce the failure rate of the power drive.
6. View from the modern office lighting design
While ensuring the quality of the lamp,
We also need to look at the two designs from healthy eye, flexibility.
In terms of Take the special product, it is a product of a side outlet, no stroboscopic, low glare characteristics.
Take the side outlet, the beam angle is 120 °, which can uniform light, effectively avoid the dark spots, protect the staff vision; also prevent staff from producing visual fatigue and improve working efficiency.

In addition, it is also a strong flexible luminaire, in office lighting, such as the office of the office, can focus on the comfortable exchange atmosphere by combining it in different styles.
The flat plug-in power interface, plug-and-play, is also convenient and fast.
Flexibility is also reflected in the installation method. The series of LED flat lamps have three types of suspended, ceiling and bridge-type installations that meet the needs of different modern office space design.
