What is the internal structure of an electric light? What is the internal structure of the desk ligh

Glass shell: generally made of clear glass. To avoid glare from the filament, the glass shell can be coated or frosted to create a diffuse reflection of light.

The number of clear glass bulbs has been gradually decreasing. In order to enhance the luminous intensity in a certain direction, an aluminum reflective layer is also evaporated on the glass shell. Some special-purpose bulbs use stained glass.

Filament: Also known as incandescent. It is the luminous body of the light bulb, and tungsten is commonly used to make single or double helix wires.

The tungsten wire is supported by a molybdenum wire bracket on the core column, and the two ends are connected with the guidewire. For safety reasons, the outer guidewire of the high-voltage incandescent incandescent lamp is also connected to a fuse. In order to increase the luminous efficiency of the filament, the air inside the bulb is extracted through the exhaust pipe in the core column, or it is vacuumed and then filled with the required inert gas.

Filaments have the following basic requirements: High melting point temperature. The melting point temperature of the filament is high, and the light emitting efficiency of the bulb is also high. The evaporation rate is small. The life of the general filament is long.

Working principle: An incandescent lamp emits light by heating the filament to an incandescent state with electricity.

The bulb is mainly composed of several parts, such as filament, glass shell, and lamp head. The metal materials in the bulb are all conductors, while the glass shell, the plastic part of the lamp head are insulators.

The light bulb, a source of light that emits light and heat through electricity, was invented by Henri Goebbels (Edison actually found the right material, i.e. invented the practical incandescent lamp, and the light bulb appeared as early as 1854). "Lighting appliances" came into being with the continuous development of human civilization. The most common function of a light bulb is lighting.

With the development of society, the use of light bulbs also plays a different role, initially may be to provide convenience for production and life, but with the progress of society, there have been obvious changes in the use of light bulbs, and there are "automobiles, landscaping, decoration" and other functional lamps for different purposes.

In general light bulbs, the luminaire is made of tungsten filament

What kind of lamp are you talking about?

Give me a range.

Don't talk about the specifics.

The principle of the touch desk lamp is that the electronic touch IC is installed inside and the electrodes at the touch of the desk lamp form a control loop.

When the human body touches the sensing electrode, the touch signal is transmitted to the touch sensing terminal by generating a pulse signal through pulsating direct current, and then the touch sensing terminal will send a trigger pulse signal to control the light on.

If you touch it again, the touch signal will be transmitted to the touch sensing terminal by generating a pulse signal through pulsating direct current, and then the touch sensing terminal will stop sending out a trigger pulse signal, and when the alternating current crosses zero, the light will naturally go out.

However, sometimes it will light up on its own after a power failure or when the voltage is unstable, and if you touch it, the signal sensitivity is excellent, and the paper or cloth can also be controlled.
