I want energy saving fluorescent lamps and LED energy saving lamps! 30

It is a kind of fluorescent lamp, but he does not use ordinary phosphor, but a rare earth element or something, which has high luminous efficiency and long life.

Energy-saving lamps, that is, three-color high-luminous efficiency energy-saving fluorescent lamps, also known as compact fluorescent lamps and integrated fluorescent lamps, refer to the lighting equipment that combines fluorescent lamps and ballasts (ballasts) into a whole, with an effective life of more than 8,000 hours.

Energy-saving lamps of the same power should be more than twice the brightness of incandescent lamps.

The incandescent lamp is a continuous spectrum, and it has radiation at each wavelength in the visible spectrum, so the chromogenic high orange socks;

1..The luminous principle of energy-saving lamps: the two poles of energy-saving lamps are ordinary tungsten wires.

When the tungsten filament is energized and heated, it emits electrons. An electric field is formed by adding a relatively high voltage to both sides of the lamp, and these electrons will be accelerated in the lamp, forming an electron flow with a certain speed and energy. The lamp is pumped into a vacuum and filled with mercury, which we call mercury.

When the lamp is energized and heated, the mercury evaporates from a liquid state to a gaseous state. Mercury atoms in a free state are formed. The electrons in the electron flow hit the mercury atom at a certain velocity, causing the mercury atom to be excited and turn into an ionized state.

It is said that there is a step, and the mercury in the excited state spontaneously falls back to its original state after a short period of time, while releasing ultraviolet light, which cannot be used for illuminationSo we coated some fluorescent substances on the inner wall of the lamp, and under the bombardment of ultraviolet light, the fluorescent substances were excited and could emit more natural light, which could be used for our lighting. The more common energy-saving lamps on the market include ordinary lamps and tri-color lamps, which are becoming more and more mainstream, which have the advantages of saving electricity compared with incandescent bulbs.

The difference is that the color rendering of ordinary lamps is low, while the lamps of three primary colors show a natural sunlight color, and are better than ordinary lamps in terms of color rendering and light efficiency. From the above, we can know that mercury plays an intermediary role in energy-saving lamps, and without mercury energy-saving lamps they will not emit light. There is very little mercury in each lamp.

2.The luminous principle of incandescent lamp: As we all know, the incandescent lamp is an important invention of Edison, which made mankind bid farewell to the darkness and ushered in the light.

But the incandescent lamp is so power-hungry that less than one-tenth of its energy is turned into light energy, and the rest is heat. So people are looking for ways to replace incandescent lamps with new light sources. Energy-saving lamps came into being.

Because it is relatively cheap and easy to make, it has been widely used, and there is a tendency to gradually replace incandescent lamps.

The spectrum of energy-saving lamps is discontinuous, e.g. at 520 nm, above 730 nm, with almost no radiation.

Incandescent lamps have a large amount of infrared light, and the pitched positive energy lamps have only a trace amount;

Ultraviolet light, incandescent lamps are almost non-existent, and energy-saving lamps have some.

Incandescent lamps are better for the eyes, and the protection of the light source for the eyes is good or bad, nothing more than the following factors: glare, strobe effect, ultraviolet content, color rendering, etc., the first few incandescent lamps and energy-saving lamps are almost the same, the color rendering of incandescent lamps is close to 1, and the color rendering of energy-saving lamps is around. The light of an incandescent lamp is more able to restore the color of the object itself.

Color temperature is the color of the light emitted by a black body when heated to a certain temperature (Kelvin). The temperature is low and white is red, high is white and yellow, then high is white, then high is white and blue, and then high is white and blue.

The working principle of incandescent lamps is simpler than that of oak dust, that is, to give the filament a current to make the filament heat and glow, and the energy-saving lamp is to use the principle of gas discharge to emit light, so if the energy-saving lamp is bright and cold, the different colors in the incandescent lamp are painted with color for the bulb, please refer to it.

Energy-saving lamps, also known as energy-saving bulbs, electronic bulbs, compact fluorescent lamps and integrated fluorescent lamps, refer to lighting equipment that combines fluorescent lamps and ballasts (stabilizers) into a whole.

Due to the limitations of the working principle of energy-saving lamps, mercury in lamps is inevitably a major source of pollution. A single energy-saving lamp contains about 5 milligrams of mercury, which is only enough to fill a ballpoint pen nib, but it can cause 1,800 tonnes of water to be contaminated when it seeps into the ground. Due to the low boiling point of mercury, it can evaporate at room temperature, and the discarded energy-saving lamp can instantaneously increase the mercury concentration in the surrounding air by hundreds of times after it is broken.

Once the amount of mercury entering the human body is exceeded, it will damage the central nervous system of the human body, and the human body can inhale 25 milligrams of mercury vapor at a time to cause death.

Energy-saving lamps, that is, three-color high-luminous efficiency energy-saving fluorescent lamps, also known as compact fluorescent lamps and integrated fluorescent lamps, refer to the combination of fluorescent lamps and ballast precipitators (ballasts) into a whole lighting equipment, with an effective life of more than 8,000 hours.

Energy-saving potato bend lamps of the same power should be more than twice the brightness of incandescent lamps.
