How can people see and the psychological impact of light is the subject of scholars' research and has been discussed for many years. Depicting light as a “lumen output†and candlelight in a working state is already a traditional way of describing and defining the amount of light required to complete a variety of characters. However, that is to say, the review is based on the visual effects of light and the effects on the psychological effects. In addition, the color rendering index and the associated color temperature illuminate the quality of the light (equivalent to the degree of true color compared to the color under sunny moonlight).
The development of light source technology has many types and colors, and it is completely inadequate to simply use a lumen measurement to be seen by a person. A good example is a low pressure sodium lamp that produces a lot of lumens, but only two colors (yellow and gray). The ability to show authenticity - except the shape of the object - has been lost under this light source. Different light sources produce different spectral ranges. Fluorescent lamps have a wide range of spectral outputs. Vision is influenced by many factors, from light intensity, distribution, color, to contrast, as well as reflection, flicker, air quality, objects and observed motion, to name a few.
Our eyes use different parts under low light and high light conditions. The eye includes cones and rod-shaped cells that operate under opposite conditions, respectively. Conical cells recognize color and detail under bright conditions (photopic) while stem cells assume responsibility for dim (dark). In the light, our pupils shrink to feel more detail, while the depth of field and the sense of light increase. In low light, the pupil is enlarged to allow more light to enter.
Measure the amount of "real" light
The light meter and recommended working light levels are traditionally calibrated with daytime vision. Typical internal light sources are based on daylight visual response. Despite this, scholars point out that the relationship between visual and internal lighting, and pupil size is closer than expected. In the coming seminars, some recommenders encourage designers to specify the light and squint of the lamp when they choose, which can provide users with better design, effect and good visual experience.
Laboratory light source system research results show that the importance of light source selection for optometry and scotopic rate reveals the conversion coefficient of optometry and squint rate applied to lumen output of different light sources. The effective lumens perceived by the eye depends on the pupil. Size and impact of vision (see table below). Some lamps, such as low-pressure sodium lamps, although the lm/w is relatively high, the calibration coefficient and the number of pupils are relatively low, and most of the light output is actually lost. However, the high-quality nano-hexachromatic electrodeless lamp has achieved good results. .
The induction lamp has a rated output with less wattage, but it has a good vision. The energy saving effect is achieved.
Lumen to lumen conversion factor
The calibration factor is used for lumens per watt of lumens produced by conventional values ​​per lumen of watts. It measures the effectiveness of the light seen by the eye. The pupil is more susceptible to blue light at the end of the spectrum.
