Can a 200 degree light bulb burn your skin?

1. Scientists have known for a long time that bright light can change the brain's internal clock, and the brain's internal clock can control a person's sleep. A recent study has shown that ordinary indoor light can also affect the body's biological clock. The long-term use of indoor lighting has invisibly disrupted the biological clock set by the ancestors for people, so as to change the inherent physiological pattern of the human body.

This will not only advance the age of maturity of human beings, but also make people's physiological rhythm disordered, and then appear palpitations, chest tightness, mental malaise and other phenomena. Other researchers believe that the strong light waves emitted by indoor lighting can cause genetic degeneration of a large number of cells in the human body, causing the increase of abnormal cells and the death of normal cells.

2. Working under the light for a long time not only causes eye fatigue, but also reduces the body's ability to absorb calcium. Because there is a big difference in the nature and intensity of light and sunlight. Natural light contains many colors and wavelengths, while indoor lighting only has yellow, orange and red, and lacks the beneficial ultraviolet rays in sunlight, so the absorption of calcium is greatly reduced.

In addition, the light emitted by the fluorescent lamp has blue and invisible ultraviolet rays, which are overabsorbed by the human body and are likely to make people's ** cancerous.

3. For this reason, experts suggest that it is best to use natural light during the day, and open the windows frequently to let sunlight into the room; People who work at their desks all day long in the office should take time out to avoid contracting modern lighting diseases. When indoor lighting must be used, the following five principles should be grasped: use a wide range of lighting, such as when reading a book on a desk, the light should shine on the entire desktop; Use uniform lighting, which means that the illumination of each part of the illuminated place should be consistent; Maintain stable lighting, and the light source should not be dim or flickering; There is no uniform standard for maintaining adequate lighting, which generally depends on the nature of the work, that is, the finer the work, the higher the illumination required; Finally, be careful not to let the light shine directly into your eyes.

How far can a 200-degree light bulb look at people? If you get too close, it will hurt**, and if you are far away from the bulb, you won't burn**.

Suggestion: young women, instep burns, redness, swelling, pain, your scald is a first-degree burn, local mild redness and swelling, no blisters, obvious pain, the treatment measures at that time are: should immediately take off the clothes and socks, put the wound into cold water for half an hour, and then rub the wound with sesame oil and vegetable oil.

Now you can apply some scald cream, kaleidohua oil, etc., but baking with a bulb is not a judgment of defeat, and the ** that has been scalded should be cooled down to prevent swelling and pain, promote swelling, and can no longer be baked with high-temperature things.

If the pain is still obvious, it is recommended to go to the hospital. Don't bake it with a light bulb anymore.

The doctor said to use a light bulb to bake out the pus in the red and swollen parts! Do I have to continue baking with a light bulb? Baking with a light bulb will not be bad for the condition.

Take a 100-watt ordinary incandescent lamp as an example, theoretically yes. But you need to keep the light less than one centimeter away from you (bring enough heat) and last for more than 3 hours, so that ** will have a more obvious reaction (varies from person to person), and it will not tan on a daily basis. However, long-term exposure should be wary of certain diseases or lesions.

Halogen lamps.

You can go to the light bulb area of the special house to see what a halogen lamp is.

Because halogen lamps come in many shapes.

It's a very bright, super bright, super dazzling light.

It's usually a very small one!

It's also a halogen lamp on jewelry or artwork.

Fluorescent lamps too.

**Will tan mainly because of UV rays.

Go buy a UV board and come back to test it.

Anyway, pay attention to sun protection. It's OK to replenish sunscreen at any time.

Don't worry about anything.

Sometimes it's possible to have sunspots, freckles, under the sunlight, possibly, but not usually.

The light of the specialty store will tan a tanned person.

Long-term exposure to fluorescent lamps will not be affected** unless fluorescent lamps without glass covers (containing ultraviolet rays.

Special) will cause harm to the human body.

If the ultraviolet rays in the light are exposed to direct light for a long time**, it is easy to cause** internal melanin deposition, resulting in dull skin tone and easy spots; And long-term irradiation will cause **dry, dull yellow, and it is easy to lead to ** lesions for a long time.

Ultraviolet rays are caused by the ionization of the noble gas in the lamp under high pressure, forming a gas conductive current, and the moving gas ions continuously give energy to the mercury atoms between the collision with the mercury atoms, and most of the photons released by the mercury atoms are in the ultraviolet region, and these high-energy photons (ultraviolet rays) produce white light between the impact with the fluorescent substance.

Generally, it will not have too serious effects, the amount of ultraviolet radiation of fluorescent lamps is low, but incandescent lamps will cause dryness, dull yellow, etc., it is recommended to use daylight as much as possible during the day, that is, the light scattered into the room outside the window to learn, and use fluorescent lamps at night.

After the fluorescent lamp is connected to the circuit, the glow discharge between the two electrodes of the igniter begins, so that the bimetal sheet is heated and expands and contacts with the static touch dao electrode, so the power supply, ballast, filament and ignitor form a closed loop, the current preheats the filament, when the heating time is 1-3 seconds, the glow discharge between the two electrodes of the ignitor is extinguished, and then the bimetal sheet is cooled and disconnected from the static contact pole, when the two electrodes are disconnected, The current in the circuit disappears suddenly, so the ballast produces a high-voltage pulse, which is superimposed with the power supply and added to both ends of the lamp, so that the inert gas in the lamp ionizes and causes arc discharge.

It emits ultraviolet rays, which lead to a tan.

It is not good for the body, the inner tube is equipped with phosphor, which is harmful to the body.

You can't use ordinary light bulbs, you can use infrared lights.

Infrared lamps are made by inserting tungsten filaments into an inflated quartz tube. The tungsten filament heats up the gas in the quartz tube under the action of alternating voltage, resulting in infrared electromagnetic waves. Infrared rays radiate outwards and can be used for heating.

Quartz near-infrared travel volt line, far infrared using transparent or translucent quartz glass as the lamp shell can produce near-infrared or far-infrared radiation spectrum. Infrared is a kind of electric wave, which travels at the speed of light, carries high energy, and the radiation intensity and wavelength of the same power and different models of red dismantling stove are not the same.
