Measurement Case Study
UPRtek handheld spectrometer solved the problem regarding the traditional spectrometer can only used in the laboratory. UPRtek is developing a series of friendly and easy-to-use interface and wish to boost the work efficiency for spectrometer users. Advances in science and technology have made life more convenient for humans. UPRtek's handheld spectrometer’s functions will continue to get ahead as well. On this “Case Study” page, UPRtek will sort out actual experiences of different kind of lighting measurement with different kind of functions in a series, hope these will help users to have further understanding on various functions and optimize the work flow.
Flicker is the problem certain lights have, exhibiting a subtle pulsating or strobing effect, most of the time barely noticeable by the human eye - however, more organizations are paying attention to flicker because it is being implicated in triggering a host of health related issues such as epilepsy attacks, migraines, fatigue, reduced visual task performance, distraction and visual impairment.Do you see the invisible problem of flicker? UPRtek - the handheld spectrometer manufacturer cares the issue that most normally ignored, therefore, UPRtek designed a Flicker meter, add Flicker measurement functions to the new generations and invite all lighting experts increase the lighting quality for new LED lights.
Much has been discussed about harmful "Blue Light", which refers to the visible blue region from 400nm - 450nm (shorter wavelength region of blue). It is also referred to HEV (High-energy visible) light and is under suspicion of causing cell damage in the retina and Age-related Macular Degeneration (AMD). For cataract patients, they need to have artificial lens replacement surgery since the lens become cloudy and causing vision loss. But, the artificial lens is not able to filter the blue light, therefore, post-cataract surgery patients are more exposed to HEV since part of the lens, which yellows with age, is removed and can no longer effectively absorb the HEV blue light. (Yellow is blue's complement). In response to this issue, UPRtek produced handheld spectrometer covers the range of visible light, it can help you to measure the blue light energy effectively and avoid the damage caused by Blue light.
Since 2011, UPRtek has been doing the research in spectrum field. In recent years, there are more and more spectrum experts entering to spectrum research field too. What is so special about it so that many people began to put efforts on? According to Wikipedia, each element has its own spectrum so that humans may accord the characteristics of the spectrum to identify each object. For example, an LED white light, it has a high energy in blue spectrum but lack of violet spectrum. For overall, the same batch of white LED lights, the spectrum characters will be the same. So, how can we find out the difference between the same spectral characteristics of the LED? Let's explore the spectrum through UPRtek handheld spectrometer!
Are you an expert of lighting research and application? If you are now analyzing light, we believe measuring the light data for a long time and checking the light deviation are necessary. After all, it is possible to make a good quality control and then reach the major purpose - bring benefit to human life!UPRtek designed and produced handheld spectrometer is not only providing you the light measurement data you needed, but also expending application functions, LOG measurement - continues measuring - is one of it, which was designed especially for research and analysis. Let's take an example, the LOGGING Mode from PG100N PAR Meter, was used for plants factory to measure the adjustable LED light, users are researching and monitoring the LED light color and its ratio in order to find the best light for plant growth and increase the harvest.
In a room without any light source, can you see the color of the apple that someone just passed it to you? In this simple test, we realized that in the absence of light environment, human vision cannot play a role and has no ability to judge colors. That is "Without light there is no color".Since there is no color when no light, then after having light, is there any problem of color identification? I believe you have had a similar experience about you buy a goods in red at the store but found that the color of the goods is not what you wished when you are home. This example tells us that different light source in different environment for human eye may receive different color from the object. So, is there any standard for color definition? Yes! Many designers they will use the color number to represent the standard red, bright red or wine red, these color code also helped the designer and the customer in the selection of color and avoided the disputes on color cognition.UPRtek handheld spectrometer is being researched as a viable tool for measuring surface colors (as opposed to only light source) when UPRtek was collecting and writing this article in 2014. This has many ramifications in the market for standardizing and validating color matches for printed material, fabric color, component color uniformity, logo color compliance. This also has ramifications for studying Metamerism.
Suspicions about the adverse effects from flicker (visible and non-visible) have been around ever since fluorescent lighting was incorporated into the work place (around the 1950s). The effects of flicker have been well studied and include, but are not limited to, headaches, mi¬graines, eye strain, fatigue, and even epileptic seizures. Even if flicker cannot be visually seen, flickering light can still enter through your eyes, reaching our retinas, traveling the neural circuitry to your central nervous system (brain), where they pound your senses, potentially wreaking havoc. In short, flicker can present a silent, most times invisible and insidious problem.Not everyone is susceptible to light flicker, and it’s hard to quantify what percentage of the pop-ulation is actually light flicker sensitive. At best, we found a source that estimates 1 in 4000 (1) individuals suffer from photosensitive epi¬leptic seizures (light sensitive seizures). It is also hard to quantify exactly what levels of flicker exceed thresholds for safety and health. Our visual senses and central nervous systems are complex and vary from person to person. Differ¬ences in age, visual acuity and bodily chemistry vary greatly and exacerbate the problem even more. Ambient lighting from multiple sources also adds to the complexity of Flicker. Do multi-light environments reduce flicker, increase flicker or both? What level of flicker severity can be considered safe for such a diverse, fluid and multi-faceted environment? In short, it is an extremely difficult problem to get your arms around. This article is using MF250N Flicker Meter processing an actual Light Wave Measurement and according to IEEE recommended standard to estimate the risk of Flicker.
