How to choose the lighting LED Pendant light method for office lighting
The starting point of any space design is human vision. The human eye will instinctively turn to the most distinctive object in the field of vision, especially the contrast of light and dark in the space. Lighting designers need to understand the visual requirements of decoration and architectural designers for the space, and enhance the lighting charm in the space, so as to give the space rich visual levels.
Office spaces usually require relatively uniform light distribution, provide comfortable and soft light, and serve people's work. The two most common lighting methods are direct lighting and indirect lighting.
Direct lighting
Direct lighting is the easiest way to meet the illuminance of the space. The light is evenly covered on our work surfaces, conference tables and ground and other horizontal areas, which is an economical lighting method.
One of the most common examples: the ceiling height is 2.8 meters, using 3×14W embedded T5 fluorescent lamp panels. The distance between the centers of the lamps is 2.4m×2.4m, which meets the uniform illumination of 300Lx on the desktop. It is the advantage of this lighting technique to provide more light with minimal power consumption.
Everything has advantages and disadvantages, and direct lighting is of course no exception. Because the main direction of the light is to illuminate directly from above, it is easy to produce a spatial cave feeling with dark ceilings and bright desktops. In addition, the brightness of the lamp itself is relatively high, and it is easy to produce strong reflections of the lamp on the computer monitor-called "light curtain reflection glare". Working in this environment for a long time can easily cause visual fatigue. Therefore, we generally only use this method for middle and low-end office areas.
When we know the pros and cons of direct lighting, we can adopt the corresponding solution: use translucent materials such as acrylic sheets or parabolic metal grilles to reduce the brightness of the light-emitting surface of the lamps. The relative position of the installation point of the lamp and the display can be flexibly adjusted to reduce the chance of glare.
Indirect lighting
When designing the space for high-end corporate offices, customers prefer to adopt a brighter space environment and create a relaxed environment.
The best working environment is, of course, to work under uniform natural light. Under normal circumstances, we will use lamp troughs to illuminate the outline of the ceiling to form a feeling of simulating natural light. With the brightness of the ceiling, the space is no longer too simple, with a certain decorative lighting effect and a good visual experience. However, the conventional frame-type light trough can only provide about 50Lx of illuminance, and the light of the light trough cannot illuminate the center of the ceiling, which is usually slightly insufficient for the office space that requires 300Lx illuminance. Need to add other lamps to illuminate the space.
We can delegate the task of indirect lighting to the ceiling-mounted indirect lighting fixture, which is also the gist of the indirect lighting method of simulating the lamp trough, illuminating 90% to 100% of the light to the ceiling, and performing secondary reflection through the ceiling, making it more uniform Ground-to-space lighting. Different from the light trough, we can arrange the lamps at will, using dot matrix arrangement or linear matrix arrangement to form a more orderly ceiling space.
We call this lighting method "indirect lighting". We use this method to deal with the space and provide a soft light environment, so that we can concentrate on our work, and the reflected glare on the screen is also controlled. At the same time, the installation of lamps is less interfered by the internal structure of the ceiling, and the installation is much more convenient.
The disadvantage of indirect lighting is that it is easy to over-illuminate indoor ceilings, creating a feeling of no distinction between primary and secondary. At the same time, because the light undergoes secondary reflection, in order to meet the illumination requirements, we need to use more power and pay more for electricity. Therefore, the design needs to be considered according to the actual situation.
Semi-indirect lighting
At this point, you may ask: In the space design of this type of space, can function and decoration be "both fish and bear's paw"? The answer is "Yes"!
introduces a lighting technique: semi-indirect lighting. It absorbs the space function requirements of direct lighting, meets our work lighting needs, and can also realize the secondary definition of space, showing the spaciousness of the space and the better integration of the sky and the ground. Semi-indirect lighting combines the advantages of both direct and indirect, and is worthy of being widely used in open offices, independent offices and residential studies.
The semi-indirect lighting method can maintain a suitable brightness ratio in the space, and is particularly suitable for use in common open office areas.
In the selection of semi-indirect lighting, we must consider the glare control of the downward light, so as to reduce the discomfort of the glare above the user's head. With high-efficiency and energy-saving light sources and lamps, the light distribution is controlled through corresponding optical devices, which can effectively eliminate the reflected glare of the screen, and will not produce excessive shadows on the shape of the object.
In terms of energy saving, semi-indirect lighting lies between direct lighting and indirect lighting. The relationship between the power and illuminance of these lamps is different from the common experience value, and the guidance of professional manufacturers is required when using them.
In addition, it is worth reminding that indirect lighting and semi-indirect lighting have higher requirements for space height. Generally, a space with a ceiling height of 3 meters or more is required to meet the full diffusion of indirect lighting.
Summarize
As far as the three lighting methods of direct lighting, indirect lighting and semi-indirect lighting are concerned, different spatial light and dark relationships are formed, and there is no absolute good or bad. The essence of this space contrast is not a criterion of right or wrong. The key is to use it according to customer needs, space needs, and users' personal feelings. Combined with the rigorous calculations of professional manufacturers, the most suitable lighting method and products for the space are obtained.
