Incandescent bulbs produce light by bringing to incandescence, or at a temperature of 2700K, a metallic tungsten filament, through which the electric current passes, positioned in a quartz or glass ampoule, saturated with inert gases at low pressure, which have the purpose of avoiding the oxidation and limit evaporation.
With this type of technology only 5% of the energy produced is transformed into light, while the remaining 95% is given off in the form of heat. One of their variants is represented by halogen bulbs.
The halogen gas present inside the bulb makes it possible to reach a temperature of 3000K, which increases its luminous efficiency compared to classic incandescent bulbs. Taking advantage of tungsten halide, which is evaporated tungsten and reacting with halogen gas, the so-called halogen cycle is created, which doubles the average life of the halogen bulb compared to the traditional one.
In this case the light emission is indirect, because the issuer is not the gas but a fluorescent material. Unlike incandescent bulbs, fluorescent bulbs are connected to the network through an inductor that limits the supply current and creates an over voltage that facilitates ignition. This device extends the time to reach full brightness for Lighting Hire Sydney.
LED bulbs
They are optoelectronic devices that exploit the optical properties of semiconductor materials to produce photons through spontaneous emission. The LEDs have a very high luminous efficiency and immediately release all their luminous capacity.
Why replace halogen lamps with LEDs? The LED lamps are first of all endowed with a particular resistance in the time that allows to avoid continuous replacements. Unlike traditional lighting means, such as incandescent halogen lamps that tend to burn out after a certain number of hours of use or ignition, those LEDs are characterized by a longer duration, able to offer a level of use truly high.
Obviously, even the type of lighting with LED lamps is superior to the classic type: note also how these particular lamps require little time to be able to illuminate at the highest levels without overheating, as happens with traditional bulbs for Lighting Hire Sydney.
Replace the halogen lamps with the LEDs: a saving choice. On the savings side, it must be emphasized that although LED lamps have a slightly higher cost, this expenditure appears to be an investment, given that consumption is much lower than that of classic light bulbs.
Let’s take a small example: a traditional 100 W lamp corresponds to an 18 W LED lamp that, over the course of a month, will save about $ 35 on the electricity bill compared to the classic light bulb.
