Have you ever wondered how the sun works and if there are any light bulbs that actually simulate sunlight? Most people don’t realize that it’s actually possible to “simulate” the sun. Many of us think of the sunlight as a yellow-white light that comes directly from the sun. The question then is, “Do these types of lights actually work?”
The answer is yes, these do simulate the sun’s rays. There are special devices called photovoltaic cells that can soak up the energy from the sun’s rays and convert it into electricity. These photovoltaic cells are so closely related to the actual process of the sun that many people call them “solar panels”. Many companies are now using this technology to generate power for homes, businesses and others.
The photovoltaic cells in these solar powered lights are actually made out of a composite material. The most common composite material is silicon. Silicon is actually a semi-conductor of electricity, but when exposed to the sun’s rays, the semiconductor becomes activated, which causes it to produce electricity. There are different layers of this composite material that have different functions; however the bottom layers are where you will find the fake sun.
There are two layers that can be found in a fake sun: one that produces light and another that heats it up. The light layer will actually create a color of blue or green depending on what the light percentage in the area is. This layer is the real thing that is behind the appearance of the sun. The middle layer is where the heating component is not transparent, but it actually resembles the real thing in that it produces heat.
Some products advertise that they are able to create realistic light using these solar cells, but in fact, they are not really creating any light. They are just simulating what the sun would do. There is no way for us to directly recreate the heat that the sun would shine off of the earth, so we can only approximate it. For example, we use white light that is slightly negative in order to get the most accurate sun shadow simulation possible. With these types of simulated sunlight products, there is really nothing that you can do to the actual solar cells.
Some companies claim that they can provide you with simulated sunlight by providing you with a chemical environment in their lab. However, there is no way for these companies to know what the actual temperature would be on the outside of the simulated globe because that is impossible to know. What they are providing you are artificial light sources that are not very realistic in the grand scheme of things. These products do not really mimic sunlight at all, but simply a fancy name used to attract customers.
