Low working efficiency? Perhaps because the office illumination is not to force!

why office is unfavorable use warm light, as warm light gives a person a kind of warm feeling, for a long time in this kind of light is easy to make people sleepy reduce work efficiency. And lively light of cool color, can concentrate better, improve the work efficiency. But want to change the office environment to improve work efficiency, order to change the light color is not well, but also the intensity of illumination.

intensity of illumination on the meaning of

intensity of illumination, commonly used in terms of interior lighting design, refers to the degree of objects illuminated, accepted the luminous flux per unit area are used to indicate, said unit for lux ( 勒克斯,lx) 。 In the UK called 'candle ( lumen） In Europe, called Lux. Specifically, 1 lux equals a candle from 1 m outside the projection on the surface of a square meter of the amount of light. 10 Lux is equal to 10 candles from 1 m outside the amount of light projected onto the object surface. Illumination is accepted by the vertical plane of luminous flux is a standard, if the tilt illuminate the illuminance is reduced.

here's office illumination means the lighting intensity of your office.

intensity of illumination high colour temperature low space can make a person feel very hot, and low color temperature and high intensity of illumination space will create gloom a tired mood. Color temperature in high office but low illumination environment, people tend to feel gloomy and tired, and reduce the work efficiency.

office illumination should be considered how to improve the science? Let's talk about illumination height and what factors are involved.

space illumination levels associated with what?

general for the same light source, the further away from the light surface light source, light intensity of illumination on the surface of the smaller; The nearer the surface light, on the surface of the light intensity of illumination. In addition, in the light source and light surface distance given conditions, a vertical irradiation compared with oblique, vertical illuminance is big; The smaller the tilt the light, intensity of illumination.

the office illumination levels associated with what? Many people first reaction is to think that with the number of lamps and lanterns, the brightness of the itself of lamps and lanterns, of course, this is also related factors. Lamps and lanterns, the more the more bright, can increase the flux, improve office illumination. In addition to the light problem, there are other factors, such as the ride height of lamps and lanterns, the area of the space and shape, the color of the wall, ceiling and floor, and decontamination situation and so on.

the higher hanging lamps and lanterns, the reflection of luminous flux, the more space the overall illumination is relatively improved. The area of the space is larger, the more close to the square, the more direct flux, the higher the intensity of illumination of the space. The more shallow, walls, ceiling, and the color of the floor surface is clean, the reflection of the luminous flux, the higher the space of the intensity of illumination.

visible, can improve office illumination by increasing the number of lamps and lanterns, brightness, promote clean lamps and lanterns hanging high, wall, ceiling and floor, etc.

but not increase illumination is conducive to improve the work efficiency? The answer is, not necessarily.

general conclusion of the present study is that within a certain range of lighting levels increase is can improve work efficiency, but with the constant improvement of the level of lighting, the improvement of work efficiency will be smaller and smaller, until the negative efficiency ( Low efficiency) 。 A low efficiency point varies with the task. Generally speaking, the more difficult tasks, namely, the smaller objects, the lower the contrast, appear efficiency is to reduce the higher the level of illumination.

by changing the task characteristics ( That is the size of the zoom or improve contrast) Than we improve the level of lighting, more can obtain satisfactory result in visual effect. Generally difficult to only by improving the lighting levels to make visual difficult task ( Small size, low contrast) Works to achieve the same level as the visual easy task work effect.

intensity of illumination required by different places reference

general situation: under the summer sun is 100000 lux. Cloudy day outside of 10000 lux. Indoor fluorescent lamp is 100 lux. 300 lux from 60 w lamp 60 cm for the desktop; Television studio for 1000 lux; Dusk indoor for 10 lux; Street lights at night is 0. 1LUX； Candle, 20 cm distance) 10～15LUX。
