The lightbar LED has changed the way of lighting in houses, exhibition halls, glitzy stores, malls, hospitals and even discotheques. The wide popularity attained by light bars that use LED is because of some fine features offered by light emitting diodes which are hardly seen in any other light source. Light emitting diodes offer lighting with high brightness without consuming a lot of energy. Working on the principle of electroluminescence, the LEDs that are used in modern light bars offer several advantages which have captured everyone’s imagination.

It is possible to narrow down the wavelength range emitted by the lightbar LED. Focused beams can be emitted at very low beam temperature, which allows you to get high luminosity without worrying about the wasted heat energy. Moreover, light emitted by LEDs isn’t harsh on the eyes as is the case with incandescent or fluorescent lights. Therefore in houses where there are children, it is not a bad idea to adopt LED lighting which is soft and whose intensity can be controlled.

The switching speed is another reason why lightbar LED technology ...
... is popular. There is no flickering. The LED can be switched on immediately, which is ideal for living rooms. Multiple LEDs can be combined and flash patterns can be built into circuits to use for decorative effect. Flashing and alternately blinking red and blue lights are not only seen in emergency vehicles but also in malls especially during festivals and holiday season. The robustness and small size of the LED used in modern light bars makes them a great component of massive lighting designs, which get great value from the versatility of the LED.

A lightbar LED usually comes with an epoxy coating which makes it more resilient to moisture, dust and corrosion. The LED usually lasts longer and also gives a lifespan of 50,000 hours unheard of in any other source of light. Replacing neon and incandescent lighting, LED light sources are also very cheap these days and hence extremely cost effective. The LEDs which are also used as indicators and for backlighting in electronic equipments are very efficient and reliable. A light emitting diode doesn’t stop working all of a sudden and instead grows dimmer and dimmer indicating that it is time to change it.

Another interesting thing in a lightbar LED is the cone shape which is specifically designed keeping in mind the refractive index of silicon semiconductors. The ideal shape of the LEDs allows maximum output of light. Moreover, lenses can be used to focus the light, when it is required that the beams be intense instead of being wider. This is why you would find LEDs with beams ranging from 10 degrees to 40 degrees. The LED has also been able to replace incandescent and fluorescent bulbs because of its excellent luminous efficacy. In other words, as current goes up, normal light bulbs emit more heat and the lighting output drops. However, this is not the case with LED, thus saving energy without compromising on brightness.
