Since the invention of the light-emitting diode (LED) in 1927, electroluminescence lighting has revolutionized the field of lighting. Its evolution has led to the creation of high-performance lighting tools such as LED panels and LED tubes. What is an LED lamp and what are its advantages? We will talk about it in this article.
LED lamp: what is it?
Electroluminescent lamp is a type of electric lamp that uses the phenomenon of electroluminescence to provide lighting. These types of lamps are created based on the operating principle of light-emitting diodes due to their low supply voltages and long service life. Following the evolution of technology and the increase in power, increasingly efficient lamp models have been created.
Advantages of electroluminescence lighting
LED lights have many advantages over traditional lighting. They offer a much longer lifespan (15 to 000 h) than an incandescent or fluorescent lamp (50 to 000 h). Despite their high lighting power, these lamps have very low power consumption due to their good luminous efficiency. This is also why they are increasingly used in surveillance and motion detection systems.
LED lamps are practical and safe lamps. They are functional from a low electrical energy which greatly facilitates their use. They do not produce ultraviolet (UV) rays and have a very low heat production. These lamps are shock resistant and largely recyclable as non-hazardous waste. Speaking of safety, LED lamps operate at very low voltage and low temperatures which is an advantage for electrical safety.
Lamps LED also offer the possibility of producing a wide variety of colours. For example, a desired colour can be obtained by combining several LEDs of different colours or simply by varying the currents that supply the different LEDs. With a white electroluminescent lamp, the choice of colour temperature is wide, ranging from warm whites to cool whites.
Note that electroluminescent lamps generally reach their full luminous power in less than a second after switching on, unlike so-called "low-energy" compact fluorescent bulbs which generally display 60% of their luminous power after 60 seconds.
