How does an Incandescent bulb make light?
Inside an Incandescent bulb, electricity is used to heat up the Tungsten Filament. The electrons in the Tungsten Filament begin to jump out to a higher energy orbit for an instance and then drop back to its natural orbit, releasing light.

The plant growth's success formula - PPFD (photosynthetic photon flux density) What is PPFD? It means how many photons hit a defined area in one second. PPFD is the unit of measure, defined by μmol/m2/s or micro-moles of photons falling on a square meter per second. Plant has various species and different categories which have different PPFD requirements.Normally, Photosynthetically available Radiation (PAR) wavelength is 400nm - 700nm. The light intensity has valuable effects on the plant due to the different wavelengths.

- Let's have an over view of the 3 common types of artificial light. The traditional Incandescent bulbs were first on the scene. Next, came the Fluorescent Lights and then LED Lights, both bringing advantages in bulb lifespan and energy savings. However, they are all three, still in use with their own distinct advantages and disadvantages. Read MoreIncandescent lighting uses heat (thermal radiation) to produce light. Sunlight and Candle light are generated in this way. Incandescent Light Bulbs also generate heat (thermal radiation) through a "filament". The filament heats up to produce light like a candle. Read MoreFluorescent Lights have been commercially available since the 1930s as long Fluorescent Tubes. A smaller bulb like CFL (Compact Fluorescent Light) only became widely available in the 2000s. These lights use a mercury vapor (steam) inside the tube; electricity is applied within the tube, which causes the mercury vapor to emit UV light, or more accurately UV radiation. The UV radiation hits the inside surface of the tube which is coated with a phosphor material. The UV radiation causes the phosphor to glow. Read MoreEarly LEDs (Light Emitting Diodes) were used mainly for small indicator lights for applications like display panels, they have been used in this way since the 1960s and they looked like the bulbs as below picture. Read MorePractically and economically speaking, LEDs seem to have a huge advantage and this is why most newly built facilities in developing countries are choosing LEDs for most of their environment lighting (e.g. factories, offices, libraries, museums). Read MoreUnderstanding the basics of what light is and where light comes from is the key to understanding LED lighting and UPRtek handheld spectrometers. However, we must first get our feet wet in the world of Science, particularly Physics and Chemistry. Here explains the lighting fundamentals in layman terms, in a straightforward, concise and practical way, without any MATH! Read MoreAs we mentioned in artificial light FAQs, a Fluorescent Light makes light in two separate steps; electricity causes mercury vapor to emit UV light, the UV light strikes the Phosphor inner lining and causes the Phosphor to emit visible light. In both cases, the same mechanisms of Energy-Atom-Electron-Photon are in effect. Read MoreAs we saw on the previous FAQ“Where does light come from?”, electrons at higher orbits that drop back to lower orbits, release photons of light. In LED semiconductors, a similar strategy is at work. Electrons jump from higher energy states to lower energy states. Read MoreLet us first explain that the color is come from light by Newton's experiment of simulating the phenomenon of rainbows; then, after the light enters the human eye, photoreceptor cells will receive and act on the light for colors from the object; at last, let’s explore what happened when the light hits on the object, through the dance of light - Reflection, Absorption and Transmission to have further understand the color. In addition, since the judgment of the color is not the same by each person, through UPRtek spectrometer to determine the color consistency, color rendering and saturation...etc. Let’s agree to disagree. Read MoreThe industries that care color performance are store display, architectural lighting design, cinema and film lighting, etc. If we assume that sunlight is the “gold standard” for color rendering or color quality, how do we rate a certain LED light? This is done with a measuring “stick” called CRI (color rendering index). A CRI of 100 represents natural color rendering quality (i.e. from sunlight, black body radiator, incandescent) - anything below that represents varying degrees in deficiency. For cinema lighting, CRI ratings for a light over 95 is considered excellent. It’s important to remember that CRI does not measure how true a color is, but measures the amount of that color in a light (sometimes referred to as the intensity or magnitude). Read MoreThe CQS（Color Quality Scale）is a new light source quality parameter developed by NIST （National Institute of Standards and Technology）for the new solid-state lighting markets.As we mentioned in the article on what is Color Rendering Index, since CRI proposed by the International Commission on Illumination caused some problems with the use of unsaturated colors and a small amount of sample colors. CQS is using higher saturation color, and proposed 15 new colors to evaluate the light source, the value of 100 represents the best quality of the light source, 0 represents the worst light source quality. Read MoreThe Technical Memorandum, TM-30-15, the new method published by IES in 2015 and has been proposed to the CIE. This new color evaluation function is expected to provide the angle of technological innovation for light source measuring, furthermore, it can help users analyze the color characteristics of the modern and the traditional solid-state light source, and thus enhance the fairness and accuracy of the measurement. Read MoreAn undesired change in visual perception induced by a light stimulus whose luminance or spectral distribution fluctuates with time, for an observer in a certain environment. Read MoreThis article compares three flicker metrics regarding percent flicker, flicker index and SVM. The comparison includes the definition comes from which organization, the definition of itself, calculation formula and the description of the range. If you want to know more about which products have related measurement functions, please click on the relative products tab. Read MoreCosine is a mathematical function used to calculate and specify the characteristics (length & angles) of triangles (Trigonometry). Below right picture is the cosine correction comparison between MK350S Premium and Lambert’s Cosine Law. The ideal value of the red circle was described by Johann Hein¬rich Lambert in 1760 and is called “Lambert’s Cosine Law”. Basically it shows how light intensity changes as the angle of the light changes. MK350S Premium cosine receiver is the blue circle; the optimized cosine and Lambert's cosine law are almost overlapped. It is more in line with international standards for illuminance measurement - JIS AA and DIN B standards and reduced measurement errors effectively. Read More
