LED spotlight guide

To become one of the most popular bulbs LED spotlight developed. These are light-emitting diodes which have the form of a semiconductor light-emitting component. This light bulb was invented in 1962. Initially, the LED served as a light indicator. In addition, it came by means of the LED for signal transmission. However, the technological development progressed rapidly, so that in the 90s, the first LED spotlight came to the market. But years ago, there were a number of applications and applications. In the 70s and 80s of the last century, the LEDs had no large luminous efficacy. Likewise, there was no variety of colors. There were only display elements in the colors yellow-green, orange, yellow and red. Replaced by these glow lamps and smaller incandescent lamps. The LEDs were used in tasks such as matrix displays. The LEDs are also used in liquid crystal screens as part of the backlighting. This is justified by the function of long-term stable lighting. Another plus is the low power consumption of the LEDs designed as cold cathode lamps.

The technical status of the LEDs

There are white LEDs that are known to be efficient. Their luminous efficacy is 303 lm / W. This is an increase of more than 50 lm / W since September 2010. Achievable is a maximum of 350 lm / W, if a color temperature of 6600 K is reached and the physical efficiency of 100 percent is present. The measurement is made in lumens, which allows the consideration of the properties of the human eye. Green to yellow LEDs achieve efficiency values ​​at a particularly high level. In contrast, the values ​​of blue LEDs are not so favorable. However, there is the pure physical efficiency. This is the indication of the conversion of electrical energy into light energy. The efficiency of mass-produced LEDs is characterized by certain scatters. The more power an LED receives, the more the luminous flux will grow.

The different versions of the LED spotlights

As diverse as life, the companies present the spotlight, There are models that have a maximum life of 10 years. This means that the spotlights are lit up to 50,000 hours. Due to the technology, the LEDs are of low power consumption. A maximum of 90 percent energy savings is possible. Another advantage is that the spotlights do not reach a high temperature during operation. Various models are approved for outdoor use, as evidenced by IP65 protection. Furthermore, there are spotlights, which are characterized by the use of 12 LEDs. Usually, these provide a bright work-fair light, which provides good heat generation, while the power consumption remains low at the same time. such lampshave additional features like the integration of one motion detectorin front. In addition, the LED spotlight in many cases characterized by a production of robust die-cast aluminum. Therefore, the use of different spotlights is also possible in commercial areas or on a construction site. Whatever the application, LED users offer many options to users.
