It's Definitely Possible! As it turns out, we can have an artificial sun on Earth, but as you might expect, creating an artificial sun takes a bit more than conducting a small experiment with regular equipment in a typical laboratory.
How Does a Grow Light or LED Compare to Sunlight?
Grow lights or LEDs have been designed to mimic sunlight by emitting full-spectrum lights that help the plant during photosynthesis. While the sun is freely available, its movement and shifting position throughout the day, week, and year poses some challenges to the plants. There are times when it’s too hot or too cold to grow any plants.

Why do plants need grow lights?
Grow lights or LEDs are capable of replacing sunlight for plants due to the following reasons: 1 They offer constant lighting, which maximizes photosynthesis and growth. 2 They can be controlled to allow you to provide the best light spectrum to match the types of plant you’re growing and their growth stage. 3 They give you the power to determine the light intensity by moving the bulbs closer or further away from the plants.
What type of light is used in grow lights?
Type of Light. Sunlight produces a full spectrum of light divided into three categories: ultraviolet light, visible light, and infrared light. Some grow lights contain a full spectrum to mimic sunlight, but some LEDs use the red/blue spectrum, which emits pink or purple colors.

How much sunlight does a plant need?
The number of hours drops to 12 under direct sunlight. Short-day plants such as Begonias require less than 12 hours of light per day, while long-day plants such as garden flowers require 18 hours of light. Geraniums and African violets are considered day-neutral plants and need only 8 hours of light to thrive.
How did light bulb change society?
In many ways, society was transformed by the advent of the light bulb. Suddenly, people could now stay up late, work, study or enjoy each other’s company without being at the mercy of the sun. A side effect, however, is that our bodies natural wake/sleep patterns have been considerably altered and artificial light is nothing like the real deal — the sun’s life-nurturing rays which are known to have a significant impact on our health and mood. In an effort to help people who spend long hours in poorly lit offices or live in areas with little sunlight (Beijing, anyone?), a team of Italian engineers has developed a remarkable LED-based lighting system which mimics natural sunlight. Yes, this is a low-input LED sun!
Is natural light indistinguishable from natural light?
According to CoeLux, the light is indistinguishable from natural light for humans, cameras or computers alike. I’m as skeptical as you are, but allegedly all of these photos are unaltered.
What are Full Sunlight Spectrum Bulbs?
Full spectrum light bulbs are designed to emit light corresponding mainly to the visible portion of the solar spectrum. In order to have a more accurate reproduction of the sunlight spectrum, these lamps need to produce infrared and ultraviolet light as well.
Which type of lamp has a good color temperature?
Other types of lamps, such as the Mercury-Vapor lamps and High Intensity Discharge lamps (HID), may have good color temperature but their light spectrum appears fractured.
What is a compact fluorescent lamp?
Fluorescent lamps display continuous spectra combined with discrete lines or spikes. The availability of such a wide range of CFLs is due to the mix of phosphors inside the tube. Each of them emits a discrete color, thus the addition of extra phosphors increases the CRI of the lamp (~80) along with its price.
How to choose a full spectrum bulb?
First of all, the lighting design engineer (or the consumer) must pay attention to the spectrum graph of the lamp. The spectrum must be as continuous as possible, without any discontinuities or spikes on the line of the spectrum graph. These lamps also emit infrared and ultraviolet wavelengths, which should be blocked by protective filters, in order to be safe for commercial use.
What is the color of a 100 watt bulb?
Although incandescent light provides us with a smooth and continuous spectrum, a 100 Watt standard incandescent bulb has a color temperature of only 2850K with a high proportion of yellow and red color. A type of incandescent bulb coated with neodymium is marketed as sunshine lamp, although the color temperature is far less than the limit of 5000K. However, it is important to note that the visual spectrum of the human eye does not fit the solar spectrum. So, these lamps may actually be beneficial, although not matching the sunlight.

Why are LED lights so popular?
Traditional LED lighting is known for unbalancing circadian cycle. The major reason being the huge quantity of blue light emitted by them. Unlike traditional LED products, natural sunlight bulbs use low blue light technology which keeps the circadian cycle in perfect order and also checks sleep disorders such as insomnia and sleep deprivation. No wonder natural sunlight bulbs are a popular choice amongst business owners and corporates.

What color are white LEDs?
White LEDs that use the new technology cover a wide range of color temperature varying from 2000K, or the color of a candle light, to 6500K, or the color of sunlight in a clear sky. And, what is more, they can duplicate the sunlight or natural light spectrum all over the said range of color temperature. Making use of these advantages, these white LEDs are employed as the alternatives to the incandescent light bulbs, as shadowless lamps or as lighting devices in display rooms.
How do illumination lights help us?
Man recognizes objects by learning their features through sight which is created by the intensities or wavelengths of reflected lights. After that, man can respond in identifications or in emotions. The faculty of seeing something includes seeing beautifully and correctly. To enhance this faculty it is necessary to design and offer adequate illumination lights with low impact to visual organs and the nerve system of the human body.
What is purple LED?
A purple light LED chip is used to make white light that duplicates the sunlight spectrum. The white LED light excited by a purple LED chip has a different emitting principle than that of those excited by blue LED chips.
How does light affect health?
Light sources, in the early days were, were limited to natural light such as sunlight and fire flames. Accordingly, our bodily functions were adapted to those natural lights. Blue lights are absorbed in the retina and its signal is transmitted to the biological central clock (suprachiasmatic nucleus) to control biological clocks. In the morning, exposure to sunlight resets the biological rhythm. On the other hand, if exposed to light at night, the biological clock may go off kilter and sleep will be negatively affected. Because of this it is preferable to choose human friendly light, or it is important to avoid bluish lights at night. Research on the impact of lights on the human body are advancing throughout the world; it will be clarified and include sufficient medical verification.
Is excitation light absorption rate antonymic?
However, there are not a few antonymic relations in these properties. For example, excitation light absorption rate is generally inconsistent with visual light conversion efficiency. Moreover, although higher concentration of doping materials, which absorb exciting light, will be agreeable to improve absorption rate, color conversion rate will be degraded on account of the mutual interference between phosphor and doping materials. Further engineering development of phosphor synthesis was made to overcome this technical issue. The working items are listed in table 2.
Does white LED have more than one phosphor?
Degradation of energy efficiency associated by a mutual interference is peculiar to the white LED that is coated with more than one phosphor. It was already explained above that phosphors, externally stimulated by an exciting light, attain broader emission at half width.
Does shorter wave length cause visibility?
In addition, a phenomenon that ample amount of light component in shorter wave length region causes trouble in visibility came to be a subject of study, standing on a fact that shorter the wave length, the light will be more easily scattered.
