There are certain differences between light-emitting diodes and tungsten filament bulbs. Light emitting diodes are simply called LEDs. Made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc. When electrons and holes recombine, they can radiate visible light and can therefore be used to make light-emitting diodes.
Used as indicator lights in circuits and instruments, or formed into text or digital displays. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. It is a type of semiconductor diode that can convert electrical energy into light energy. Tungsten filament bulb is an incandescent lamp made of tungsten filament, which can produce a continuous spectrum and is used in the visible spectrum region of 400 to 780nm. As a visible light source in spectrophotometers. Its spectral effective area can extend to 3μm, so it is also used as a light source in the near-infrared region.
The difference between light emitting diodes and tungsten filament light bulbs
1. The reason why the light-emitting diode is durable is because of its light-emitting principle. The light-emitting process is not accompanied by a large amount of heat release, which greatly increases the lifespan. The brightness of tungsten filament bulbs comes from the high temperature and heat of the tungsten filament itself, which is accompanied by its own sublimation and consumption. Whether it is durable depends on general data and average values.
2. The light-emitting diode mainly depends on the chip inside. The quality of the chip determines the life of the bulb. The life of a tungsten filament bulb mainly depends on the quality of the tungsten filament.
3. The fundamental principle of light-emitting diodes is the energy level transition of electrons. In the middle of the tungsten filament bulb is a section of metal tungsten filament. When current passes through, the tungsten filament is heated and activates the gas in the bulb to emit light. Tungsten light bulbs were once the most commonly used light bulbs in daily life, but in recent years they have been gradually replaced by energy-saving lamps. However, tungsten filament bulbs still occupy a large share of the market, and their simple shape makes them very popular among designers and used in various interior designs.
