Light Bars Led The Lights For The Future

In an incandescent light bulb 90% of the energy it uses ends up as heat

. Only 10% is converted into light. This makes the incandescent bulb a low efficiency light source. The more efficient fluorescent was a bit more efficient but until the compact fluorescent arrived its use was limited. The latest light source to have developed is the light emitting diode or the LED. They are mounted in sets of two or more in light bars LED for many uses.

Due to the fact that they do not use vacuum chambers like incandescent bulbs and fluorescent bulbs they are called solid-state light sources. The early LEDs were able to emit only red light and the intensity was very low. These were used as indicator lights. First they were used in expensive equipment such as laboratory equipments and x-ray machines. Later they were used in TV sets and other cheaper items and came into widespread use. Further research was able to discover light emitting diodes of different colors and finally the ones with high intensity light were made. These high intensity light ones are used in light bars LED

These new light emitting diodes are used in a variety of applications such as street traffic signal lights and ambulances in addition to being used as indicator lights in appliances. One use of the more developed high intensity light emitting diodes is in torchlights. Unlike the tungsten filament bulbs these bulbs are able to emit high intensity light and also they last a long time. There are some brands of torchlight that guarantee the bulb for more than 50,000 hrs. When these are used in light bars LED they could be used to illuminate large areas. These light bars are replacing neon lights that were decorating the streets some time back. The neon light uses a lot of energy to burn and this is the main reason for them to be replaces with LEDs.

Though the light bars LED are presently used in small scale for table lamps and emergency lamps the full-blown use of these solid state light sources have not yet arrived. However they are used in Kitchen illumination and such other applications in addition to their usage in trucks fire engines and ambulances as signal lights. Due to the present trends of energy saving the future holds a lot for the light bars LED, as they are ideal energy efficient lighting systems. There will be brighter and larger LEDs being developed to fulfill the need of the hour.

When the light bars LED come to illuminate offices, hotels and restaurants there will be a boom of LED lights as they are going to save a lot of money and the Compact fluorescent bulb which is the favorite over the incandescent bulb at the moment will be required to back up leaving the opportunity for the new discovery to take its place as it is more economical and more efficient.
