There is light everywhere in life：natural light and artificial light( such as Indirect Light Plants), but do you know what is the Effectiveness of optical radiation? Below is 8 kinds of the Effectiveness of optical radiation.
From natural light to artificial light
Light is life – and essential for people, animals and plants. For a longtime, before people were able to use artificial light, natural daylight was the only light available.
Natural daylight has two components: sunlight and skylight. A principal characteristic of daylight is its variability.
From natural light to artificial light
For a long time the sun was humanity’s only source of light. About300,000 years ago man
began using fire as a source of heat and light. The first artificial light source was fire.
Modern lighting concepts combine both natural light and artificial light – for our improved well-being and health.
Based on the latest modern understanding of light (radiation), combined with new technologies, new understanding and new goals in related fields, to provide lighting that is more suitable for the needs of human beings in the 21st century.
- Light for Human Visual
- IpRGCS (intrinsically photosensitive retinal ganglion cells) are photosensitive through the expression of melanopsin.
- Photosynthetically active
- Poultry Lighting
- Bactericidal / Germicidal / Microbiocidal radiation Optical radiation capable of inactivating or killing pathogenic micro-organisms
- Action spectrum for previtamin-D production
- Photochemical and Photobiological Actinic Radiation . Actinism is the property of optical radiation that enables it to cause photo chemical changes on certain living or non-living materials, and radiation capable of causing such changes is referred to as actinic radiation. Optical radiation also poses a potential health hazard for both human skin and eyes.For example,overexposure to ultraviolet and blue ‘light’ can cause common sunburn, photo-keratitis (welder’s eye) and burning of the retina or cornea
- Opto- electronic conversion function (OECF). Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials. When the semiconductor is exposed to sunlight, it absorbs the light energy to electrons.The electrons flow through the semiconductor as because other layers of the PV cell are designed to extract the semiconductor. Then the current flows through metal contacts – the grid-like lines on a solar cell – before it travels to an inverter.
According to several studies, the best light intensity to bring out stress colors is 120 – 150 umol/m2/s, The Special Designed Stylish Desktop Plant Light for Indoor Plants– wooden Base, environmental protection and beautiful. Coloring for succulents, prevent form spindling, makes the plant grow better.
