What is a Light-emitting diode (LED)?

ene tech led 2022.02.16

LED(Light-emitting diode) is a semiconductor device. 

Wikipedia interpreted as “A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. 

Electrons in the semiconductor recombine with electron holes, releasing power in the form of photons. 

The power required for electrons to pass through the semiconductor bandgap determines the color of the light (corresponding to the energy of photons)

Using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device, get the white light.

What are traditional light sources?

ene tech 2022.02.16 02

Traditional light sources produce lights through tungsten wire.  

As bulbs, fluorescent lamps, metal halide lamps, sodium lamps, mercury lamps, incandescent lamps, and so on.

What are the advantages of using LEDs compared to traditional light sources?


As mentioned above, efficacy is the first advantage of LEDs compared to traditional light sources. 

Light efficiency is a standard used to compare light output and energy consumption.

The equal amount of light LEDs as traditional light sources, less 50%~90% energy waste, which results in cost savings.

What’s more, LED fixtures do not require ballasts. 

Ballasts will need extradition electrical. if there is no ballast, it will reduce 15% ~ 20% power


LEDs, being solid-state components, are unlike incandescent and fluorescent bulbs as they contain no tubes or filaments. LEDs are much less prone to damage from external shock. 

LED will not damage when it hits the floor.

Long life:

LED lights average 50,000 hours of life. Depending upon the application, some LED lights last 30,000 hours, some last over 100,000 hours. Fluorescent tubes average 30,000 hours, and incandescent and HID bulbs 1,000 – 5,000 hours. Long LED life means far lower maintenance and replacement costs when comparing LEDs to traditional light sources. Led is more suitable for occasions that are difficult to replace.

Environmental and health:

LED lights to contain no mercury or chlorofluorocarbons (CFCs), last longer and produce less waste, and are made from fully recyclable materials. Even the led housing fixture with aluminum, aluminum is recycled material. Thus, recycling costs are minimal when compared to traditional light sources. LED lamps are green lighting in the 21st century.

Full Range of Colors:

LEDs are available in a full range of colors, and the color is controllable.

The color is gorgeous, the luminous color is pure, and the spectral range is narrow. It will show colorful or white light through the three primary hues of red, green, and blue.

Light controllability:

Include spot shape, light wavelength, combination, intelligent control, etc.

Design Flexibility:

Because LEDs are thin, they can apply for applications that traditional light sources are impractical. For example, the street light application is street roads, roadways, spot parks. 

The linear application is indoor and outdoor. Apply for cabinet, bathroom, bedroom, retail shop, etc.

The explosion-proof application is hazardous sites, dusk sites, gas stations, etc. 

The stadium sport light applies to basketball courts, football fields, and stadiums. 

Different scenes use different lamps.

Instant On: 

LEDs fast to light up your room. A typical LED will achieve full brightness in less than a second. LEDs are ideal for use in frequent on-off applications.

Silent operation: 

There is no flicker or buzzing with LED lighting. It is the best choice for occasions where use in precision electronic instruments. Suitable for libraries, offices, and other occasions

Low Heat: 

LED lights produce much less heat than traditional sources.

When compared to traditional light sources, so means confined areas requiring many lights won’t high request ventilation.

Cold Temperatures: 

Unlike fluorescent light sources, cold temperatures do not impact the performance of LEDs.


Most LEDs are easy to dim. 

Solar Power: 

Because LEDs draw significantly less electricity than most traditional light sources, powering an LED fixture with solar panels is now viable in many applications.

No ultraviolet rays, no mosquitoes:

 LED lamps will not produce ultraviolet rays, so there will not be many mosquitoes around the lamp source like traditional lamps. The interior will become cleaner and cleaner.

Voltage Adjustable: 

The voltage is adjustable from 80V to 245v. The traditional fluorescent lamp lighting by the high voltage released by the rectifier. When the voltage decreases, it is not lighting. LED lamps can light up within a range of voltage and adjust the brightness.


In general, LED lamps are still much better than ordinary lamps. At least they can save money and do less harm to the eyes. Moreover, the performance of LED lights is much better than traditional lamps. There are many advantages and disadvantages of LED lamps, so it is worthwhile to use LED lamps, which meet the requirements of low-carbon and environmental protection. There are more and more led light sources on the market.
