In our daily lives, the led downlight are always playing an important role in illumination. This kind of LED luminaire gives out light from a cavity of the top ceiling. Comparing with the incandescent lamp and the fluorescent one, the effective LED downlight has lower energy consumption, and it generate less quantity of heat, however it possesses high brightness.
What does the term downlight means? We always call LED a luminaire as downlight if it is instalLED in a cavity of the ceiling. It got its name for its light comes from the ceiling. If the LED constitutes the downlight, in order to distinguish it from other downlights with different technologies, we call it the LED downlight. With the help of the LED downlight, we can light up a whole area for it can shine down broadly, and it can also shine narrowly just like a revelation light. Occasionally, it is calLED as inset light.
Obviously, from its name, we can know the light source of the LED downlight is the LED. As we all know, LED is the abbreviation of light-emmiting diode, it is just the source of the light. Be similar to the fluorescent lamp or the incandescent one, the LED downlight lights up by using the electrical power. You may be amazed when hearing of the LED lights can only emit red light when it was first invented, but it is the reality, nevertheless, with the development of the technology, they emit a variety of colors. Among all the colors, the 2 most widely used colors for the LED downlight is warm white and neutral white, the former is similar to the color of the incandescent light, while the latter is similar to the fluorescent one.
People may ask: when we choose the LED downlight or other LED lighting? There are many reasons can account for this, and the most important one is it is much cheaper when comparing with other light bulbs, and they have a longer service time, at the same time, it consumes less energy and emit much more light. According to statistics, a 15-cm LED down light can help us save about $265 each year.
Comparing with the traditional lights, the LED downlights are much more effective, environmental.Unlike the LED ones, the ordinary light burns out much more quickly, because there is too much heat, however, the light of the LED light is generated electronically, so it produces nearly no heat.
Except the energy saving, the LED downlight still has other advantages comparing with the fluorescent one. The fluorescent one will damage the environment for it contains mercury, while the LED light is mercury free.
Usually, the LED downlights can last for nearly 50,000 hours, an estimation of 23 years of lighting. People may think that the LED downlight are much more expensive comparing with other kinds of downlights when they first see the price label, but in fact, it has a long-term interest. This kind of light will never burn out, they are likely to dim. Then how to identify if the LED downlight is end? It is easy, if it only emits 70 percents of the light they originally produce, then the light should be changed.
