Scientists invented the cold light lamp by studying the luminescence principle of fireflies.
Fireflies have specialized light-emitting cells, and there are two classes of chemicals in the light-emitting cells, one called luciferin and the other known as luciferase. Luciferin can consume ATP under the catalysis of luciferase and react with oxygen, which produces an excited state of oxidized luciferin, which releases photons when oxidized luciferin returns from the excited state to the ground state.
The energy released in the reaction is almost all released in the form of light, and only a very small part is released in the form of heat, and the reaction efficiency is 95%, so the beetle will not be burned by overheating. So far, humans have not been able to create such an efficient light source.
By studying the principle of fireflies' luminescence, scientists invented cold lights, which are low-temperature light sources that do not generate heat during operation.
Because the vertical mold has small power, high illumination, good color temperature, and basically does not produce heat energy when it emits light, people also give it a nickname from the perspective of energy saving and health"Green lights"。
The cold light lamp changes the shortcomings of low luminous efficiency and high temperature of the thermal light source lamp, and can reduce the heat by more than 90% compared with the thermal light source lamp, saving energy and improving the power conversion efficiency.

It's cold light. The glowworm's luminaire is located in the abdomen, the chemical inside the light source, and this light, although bright, has no heat. Generating a magnetic field, it is a kind of cold light.
The cold light they emit not only has a high luminous efficiency, but is also very soft, which is very suitable for human eyes. Fireflies are also not overheated. So far, humans have not been able to create such an efficient light source.
The luminescence principle of fireflies is that fireflies have special luminescent cells, and there are two types of chemicals in the luminescent cells, one is called luciferin (in fireflies is called firefly luciferin), and the other is called luciferase. Luciferin can consume ATP under the catalysis of luciferase and react with oxygen, which produces an excited state of oxidized luciferin, which releases photons when the oxidized luciferin returns from the excited state to the ground state.
Almost all of the energy released in the reaction is released in the form of light, and only a very small part is released in the form of heat, and the reaction efficiency is 95%.

Among the many light-emitting animals, fireflies are one of them. There are about 1,500 species of fireflies, and the colors of their cool light range from yellow-green to orange, and the brightness of the light varies. The cold light emitted by fireflies not only has a high luminous efficiency, but also the cold light emitted is generally very soft, which is very suitable for human eyes, and the intensity of the light is relatively high.
Therefore, biolight is a kind of light that is ideal for human beings. Scientists have found that the glowing device of the firefly is located in the abdomen. This luminaire is composed of three parts: a light-emitting layer, a transparent layer and a reflective layer.
The luminescent layer has thousands of light-emitting cells, and they all contain two substances, luciferin and luciferase. Under the action of luciferase, luciferin fluoresces when it is oxidized with the participation of intracellular water. The luminescence of fireflies is essentially the process of converting chemical energy into light energy.
As early as the 40s, people or the middle school created fluorescent lamps based on the study of fireflies, which changed the source of human lighting a lot. In recent years, scientists have isolated pure luciferin from the luminescent device of fireflies, and later isolated luciferase, and then chemically synthesized fluorescein. A biological light source composed of a mixture of fluorescence, luciferase, ATP (adenosine triphosphate) and water, which can be used as a flash light in mines filled with ** gas.
Since this light has no power supply, it will generate a magnetic field, so it can be illuminated by a biological light source to do work such as clearing magnetic mines.
Nowadays, people can use the method of mixing certain chemicals to obtain cold light similar to biological light, which is used as safety lighting.

In the night sky, under the bright moonlight, fireflies carrying lanterns flew out one by one. It is the "teacher" of our human beings. Because scientists have invented a light ...... that does not hurt the eyes through the light of firefliesArtificial cold light.
As early as the 40s, people created fluorescent lamps based on the study of fireflies, which made a great change in the source of people's lighting. In recent years, scientists first isolated pure lucifer from the luminous device of fireflies, and later isolated luciferase, and then used chemical methods to synthesize luciferin, luciferase, ATP (adenosine triphosphate) and water mixed into this bucket light source, which can be used as a flash in mines full of ** gas.
Now people can have a method of mixing a certain chemical Senzi abrasive to obtain cold light similar to biological light, which is used as safety lighting.
In our eyes, the firefly is just a creature that can emit light, but in the hands of scientists, it has become a flashing light. Therefore, we should observe the revelations of nature in our lives.

Since the invention of electric light, human life has become convenient and enriched. The main function of the electric lamp is to emit light, and only a small part of the electrical energy is converted into visible light in the process of emitting light, and more energy is wasted in the form of heat energy, so most of the heat energy is wasted when the electric lamp emits light. Whether it is sunlight, lights, or candlelight, they produce a lot of heat while emitting light, so we call this kind of light thermolight.
Thermal light can also be caused in some dangerous places**. Is there a light source that only emits light and does not generate heat? Scientists hope to develop a new light source, cold light, which is much safer to illuminate.
There are many animals in nature that can emit light, such as fireflies, crustaceans, and certain fish, which do not heat up while emitting light.
Boyle was a famous English scientist in the 17th century, and he was interested in glowing fireflies from an early age. Once he caught a bottle of fireflies, and at night, these insects could actually light up the room, and the cold light was very soft. Boyle thought:
Why do fireflies glow at night? What does the glow of fireflies have to do with their surroundings? So he pumped the air out of the bottle, and as the air gradually decreased, the light became fainter and weaker, and when he refilled the air, the fireflies slowly lit up again.
It turns out that fireflies can't shine without air!
Boyle's in-depth research revealed that there was a luminescent-like thing in the firefly's abdomen, and there was a luminescent substance in it - fluorescein. When a firefly inhales air, this substance combines with oxygen in the air to emit light, and this light does not produce heat, so Boyle called it cold light.
With the development of science, human beings have been able to artificially synthesize fluorescein through chemical methods and mix certain chemicals to obtain cold light similar to biological light. Cold light is used in lighting fixtures, which greatly improves safety.
Cold light was also discovered by scientists based on biomimicry. On many special occasions, cold light plays an important role. This story teaches us that science is not just about contemplation, and that observation is also important.
The white row on the tail of a firefly is where it emits light, called a luminaire. Firefly eggs, larvae, pupae and adults can all emit light. The luminescence of firefly larvae is believed to have the effect of warning and intimidating predators, and adult insects are thought to use flash to identify, courtship and trap. >>>More

The light-emitting organ of a firefly is located below the posterior end of the abdomen, where it has light-emitting cells. There are many tiny trachea around the light-emitting cells, and there are luciferin and luciferase in the light-emitting cells. Fluorescein is activated when it receives energy from ATP. >>>More
