In today’s times lighting owns various applications to its account. The world is revamping its appearance by illuminating the surroundings with newfangled lighting technologies. Interior articulation through lights is integrated at myriad places, be it at residence, office décor, retail display, ambience and what not. Read on to find the top notch lighting techniques that have been implemented worldwide.

Compact florescent lights

Mostly hotels and residence make use of compact florescent lamps. Most suited for embellishing interiors, florescent lampshades contribute to be good architectural lights. Popularly called as CFLs, they are preferred over incandescent lights, due to less energy consumption and easy insertions. The technology behind compact florescent light employs a glass tube loaded with argon gas and mercury. The presence of filament at each end of tube is coated with boron that emits light.

The spiral shaped florescent lights have gained much popularity. The light emitted at the epicenter of spiral in comparison of other shapes emanates much radiation. This illuminates the surroundings extensively.

The mechanism

There are three operating areas of these carbonate based lamps. The operating mechanism goes in the sequence of preheat, ignition and run. To gain a resonate output out of the circuit, it is important to follow the sequence strictly. The circuit ignites at a preheat frequency to light up the filaments of the tube. This inflaming happens to be at a fixed time so that the circuit processes is not being dissuaded.

The voltage of CFLs ideally ranges from 50 to 150 volts. The controlled circuit system plays an important role in managing the voltage. It rectifies and smoothen the main voltage to raise the amplitude of several hundred volts. This subsequent high voltage wave square steers resonant output and manages the frequency to execute the lamps operational properties.

Halogens lights

Quite similar to incandescent lampshades, halogens also use electrical current heat wave to ignite the filament. The tube is capsulated inside a tiny quartz case in which a tungsten filament is placed. The heat wave ignites this filament to produce heated temperature of around 2500 degree Celsius. The raised temperature illuminates the filament radiating sparkling white light.

The mechanism

The use of quartz is important to prevent the filament envelope from burning. Halogen lights employ the use of gases belonging to the halogen group. Given to their unique property, halogen gases fuses with the tungsten vapors very easily. The gases of halogen group are also good temperature moderators. As the temperature gain momentum the halogen gases combines with tungsten atoms and accumulate on the filament. This process of constant recycling of the electrical waves lends stability to the lamp as compared to the incandescent lights.

The electrical properties of halogens are different from the fluorescents. Firstly, there is no requirement of high voltage ignition. The lamps start with moderate electrical current ranging from 11.2 to 11.7 volts. Halogen convertors regulate the main input voltage, bringing it to the level of the required voltage range. This ideal voltage management makes halogens perfect commercial lights, to be used for spot lightings and other applications which require high intensity illumination.
