LIGHTING MEASUREMENT SERVICE
If we didn't have light, there wouldn't be life. Light is a source of energy and has a significant impact on health. Finland has a long dark season and it is therefore important that homes, workplaces and public spaces are equipped with proper and healthy lighting.
Healthy light can also be produced with artificial light, which Finns have to rely on for a larger part of the year. Healthy lighting is, for example, that the space in which you are in has sufficient luminousness, adjustable, even and unscrupulous lighting. Light sources must also be of high quality: light colouring (CRI) suitable and colour-coloured, light vibration as low as possible and efficiency in light source good.
Special attention should be paid to the placement of light sources and the production of light from lamps. The light source must not hit the field of vision directly. Reflections from different surfaces, such as displays, TV and worktops, must be weeded out. All reflective surfaces between the object of the gaze and the viewer must also be eliminated.
Surface contrasts, lighting intensities, colours and reflection ratios are essential key factors in the rendering of spaces. In indoor lighting, one of the most important features is the colouring capacity of light sources. High-quality coloring reproduces colors correctly and this increases the availability of information about the environment. Light and colour affect people's state of mind and, by doing so, work efficiency.
The right light orientation and positioning will remove harmful shadows from the main viewing target. On the other hand, light orientation and shadow formation are important factors in identifying the shape of the viewing object. They also provide depth and space impressions.
Lighting has a great impact, especially on work. It affects, for example, employee productivity, occupational safety and general well-being. It has been studied that demanding visual tasks have achieved increased productivity as lighting intensity (snow) has increased over baseline, and reduced the number of errors as the alertness level rises. Different farms and their uses have different levels of requirements for lighting. Spaces that do not work generally require about 50-200lx, while spaces requiring accuracy about 800-2000lx
Efficient work is only possible if the ergonomics of the workstation are in order. It is recommended to control the lighting of the workstation, for example, with different glasses with presence sensors or a workstation-specific light switch. They save energy when a person is away and provide individual lighting. The employee can be at the workplace for a large period of time meetings, so that the presence identification does not shed light on the premises in vain. With individual guidance, employees can adjust the lighting they like.
KVS Oy has brought in measuring equipment that utilises the latest technology to help its customers. This equipment allows us to examine e.g. lamp or mode CCT, LUX, CRI, CIE1976, CIE1931, PPFD & PFD, CQS, Duv, LambdaP, S/P ratio, TLCI, GAI, BLH, Flicker and HCL and almost 40 other measurement values.
Lighting measurements are carried out to ensure that there is sufficient light.
The lumen value (lm) indicates how much light the lamp produces in its environment. The higher the lumen value, the brighter the lamp.
Lux (lx) Indicates illuminance
How high the luminous flux hits a surface of a certain amount
Kelvin (k) tells you what color the white light is
1700K-3500K Warm white (stuffy/yellow white)
4000K-4500K Natural white (pure white)
5000K-6000K Daylight (Bluish White)
More than 4000K is recommended in office space
CRI The color rendering index tells you how pure light is produced. Sunlight is 100%
For office use, CRI should be more than 85Ra
UGR Bullying is a sign of the amount of bullying when viewed from different angles. The lighting standard defines certain values for the premises, which the glare value should not exceed. The values are based on the recommendations for indoor lighting in accordance with the European standard EN 12464-1.
In office space, URG must be 19 UGR
The quality of lighting has a significant impact on the productivity and well-being of employees
The light should be clear to carry out the work, but it must not be blinded. The UGR is essential for the implementation of lighting in companies' office space.
We present a few turpentine:
BLH= BLUE LIGHT HAZARD
Radiation percentage of blue light
Radiation efficiency ratio of blue light wavelength (401 nm to 500 nm) in THE LED. BLH can be applied to museum lighting, for example, which avoids damage caused by blue light in antiques.
In addition, users can understand the risk level of blue light around them, show high energy visible light effectively and protect them from potential dangers. This is recommended for lighting manufacturers, LCD and OLED display panels, opticians and ophthalms, among others.
HCL= HUMAN CENTRIC LIGHTING
Biologically active light
Helps create a more comfortable and healthier lighting environment.
Our eyes observe light and color. The retina of the eye absorbs light and converts it into a nerve signal that transmits signals to our brain for visual imaging and physiological function.
Melanopsin is responsible for non-visual functions such as the body clock, the release of melatonin and others. Melatonin is also known as sleep hormones, which take care of the biological rhythm of the human body. During the day, it is produced in a smaller amount to keep people awake, otherwise you will feel tired and lethargic. As a result, light intensity and different CCTs, that is, the colors of white light, easily affect the circadian rhythm, hormone secretion and external behavior.
This is the main reason why light therapy can mediate depression and sleep disorders.
LUX IMAGE DISTRIBUTION
LUX light distribution
The measuring equipment may be used to measure regionally the light distribution of the holding or product concerned. In this way, we can easily verify whether the required amount of light is required in the premises.
It is also interesting to carry out various lighting updates before and after the measurement. Various verifications will also be made easier, and as a result, the preparation of invitations to tender will be made easier when users have knowledge of the baseline.
