Commercial office building LED lighting design
The modern office is a working environment composed of a variety of visual tasks, not only to meet the basic reading and writing, but also to generate a pleasant and comfortable working atmosphere, to ensure the physical and mental health of the staff, to stimulate the high work enthusiasm of the staff, so as to improve the work efficiency.
High-quality office lighting design can effectively improve work efficiency. The factors that determine the quality of office lighting are: illuminance, uniformity, glare, brightness distribution, color temperature and color rendering index. At the same time, it is necessary to comprehensively consider the overall intelligent control, safety and energy saving. And so on, to create a comfortable, harmonious and efficient working environment.
1. Elements that must be considered in the lighting design of business office space
The following major factors must be considered:
Color temperature selection: The color temperature of the general office lighting source is more suitable between 3300-5300K.
Color rendering index: The general color rendering index of the office lighting source is selected in the range of 60-80, and factors such as initial investment, installation and maintenance, and energy saving should also be considered.

2. Lighting design guidance for key functional areas
Reception area lighting design
The front desk is the place where the company shows a good image. In addition to the decoration design of the front desk, the temperament of the staff and the decorations, this area pays attention to the light and shade distribution of the overall space and the fit of the spatial order, which can give people a comfortable and gentle feeling. The first impression of the company, especially in the company's LOGO lighting, should be clear and bright, leaving a deep impression on visiting customers and other personnel.
Comprehensive Office Lighting Design
A comprehensive office generally refers to a large-scale office with an office area of more than 80 square meters, divided or separated by multiple separate work spaces in the middle, and multi-department co-working. Its lighting design generally only provides uniform lighting, but it is also divided into general lighting and local lighting, which each contribute 50% to the illuminance of the operation. Also need to pay attention to the control of glare and brightness ratio. However, for the division of different layouts and the distance and density of the space, different methods should be used for design.
Independent office lighting design
The independent office is mostly the place where the middle and senior management personnel of the enterprise work. It is generally private and closed, and it also has the functions of receiving guests and important business negotiation.
In the lighting design, it is required to combine general lighting and local lighting. For example, the illuminance of the office area (writing desk) is required to be above 500LX, so as to have sufficient illuminance to ensure normal office needs. For the small area for negotiation, local lighting can be used, such as setting up table lamps, floor lamps, or designing small spotlights and wall lamps on the wall to meet the required lighting effects, and pay attention to the difference between office and negotiation light. transition between.
Conference room lighting design
The conference room is a medium-to-large office area integrating discussion, training and group activities. It requires a variety of flexible and intelligently controlled lighting effects to facilitate various types of collective work.
The lighting design of this area requires a combination of general lighting and local lighting. In addition to providing sufficient illumination to ensure the writing and office work of the participants, the rostrum area is highlighted by local lighting control to reflect that the rostrum area is guided and prominent. The key lighting effect is convenient for special lighting needs such as projection, handwriting whiteboard, and speech.
Focus on reflecting the compactness of the participants and create a better discussion atmosphere. Generally, the method of the middle illumination is higher than the surrounding illumination (or the surrounding lights are turned off to highlight). The overall color temperature is controlled at 3000K, and the average illumination is above 400LX.
In the slide show and the content and patterns on the projection can be clearly seen, the text recording work of the participants should also be considered. Therefore, the surrounding illumination setting should be around 150LX. At the same time, taking into account the relationship between the participants and the projection distance and the overall energy-saving effect, a stepped design is implemented for the contrast, and the brightness is gradually increased from the front row to the back.
Based on the principle of highlighting the speaker's image and not affecting the speaker's feeling, the illumination ratio of the podium should be controlled at 90%-100%, the auditorium and other positions should be adjusted to 50%-60%, and the basic illumination should be controlled at about 200LX.
Living room lighting design
The meeting room is a place where the company sets up special reception for foreign guests, and it is also an important place to reflect the internal culture of the company. In terms of lighting design, it is necessary to use different lighting methods according to the differences in corporate culture, decoration style and interior layout, but one thing is The common thing is to create a comfortable and relaxing space environment atmosphere.
Pantry lighting design
The pantry is a place specially set up by the company to provide employees with a short rest and relaxation during working hours. It is also a manifestation of corporate culture and a kind of welfare, but this area plays a very important role. Therefore, in the lighting design, it is necessary to consider the corporate culture and connotation, and focus on creating a warm, comfortable and relaxing space environment
