In the previous article we talked about units indicated on the packaging of the bulbs or bulbs. Everything (including this article) could be granted for some but we need to understand the technical terms that are often used but which for some may not be clear, maybe we dwell a moment but we sure not be misrepresented.
Then we said, the lamps can be of different types: from brand new halogen addition to fluorescent led to, each with distinct characteristics. Vediamole in detail.
These types of bulbs, which still fall in the typology “incandescent” are often inside the bulb a gas–iodine or kripto–that helps prevent the tungsten vapor deposited on the walls, thus increasing durability compared to traditional models.
Even the luminous efficacy is double, equal to 22 lumens per Watt and emit white light in more shades.
Halogen bulbs have standard connections, but in many variety of shapes and wattages up to 100 W and beyond.
There are 2 versions. Very low voltage halogen bulbs, which require a transformer for connection to the mains; and those high voltage, which do not need transformers, but cannot be used directly in place of incandescent types having the same attacks of traditional lamps.
The IRC halogen energy saving halogen have twice the length and 20-30% more realises with significant reductions in energy consumption.
Are suitable for localized and accurate lighting with decorative effects.
You work a lot in the kitchen, above the countertop and the kitchen and bathrooms.
Also called “energy saving bulbs,” are the compact version of the neon lights, known as “tubular fluorescent” and used primarily for lighting public premises.
CFLs are made up of one or more glass tubes, spiral, globe or bulb, inside which contains mercury and other heavy metals; on each tube is mounted to an electrode.
Flourecent with integrated reactor can directly replace incandescent lamps, as they have a screw base E27 or mignon E14. Luminous efficiency is 50-75 lm/W, up to 7 times faster than incandescent ones.
Invisible ultraviolet radiation generated by electrical discharge in low pressure mercury gas are transformed into visible radiation through the adoption of fluorescent powders lining the inside of the tube.
There are models with power of between 3 and 30 watts.
Low consumption are considered as while absorbing a much smaller amount of energy compared to incandescent models have an excellent light output. In practice, than conventional models, scatter a little energy into heat and manage to turn it almost entirely into light.
They also have a much longer duration: newer models can work for 20,000 hours, namely 20 times longer than incandescent bulbs. There are more shades: the effect is different from that of traditional bulbs, but the color rendition is still high.
Compact fluorescent bulbs are recommended in all environments, especially when the light must not be switched on and off too frequently (at intervals of less than 15 minutes); This increases the lifetime and consume less energy.
The abbreviation stands for “Light Emitting Diodes”, or light-emitting diodes. These devices, which measure a few millimeters, base their operation on semiconductors that convert electricity into light. Are a convenient alternative to traditional lighting sources inside and, if protected, also outdoors.
The light producing the led has specific colors–red, yellow, green or blue – depending on the semiconductor material used.
With particular combinations of several LEDs you can get custom shades of color with an almost endless choice. The white light is obtained by coating of yellow a blue led.
As a major type of bulbs for lamps defined on PAULDIGO, the LEDs have a duration which can reach, in newer models, up to 25 years. They are also very robust and have a very high impact resistance; Once installed, do not require any maintenance. Can withstand very low temperatures, up to -30 or -40° C and are therefore suitable for outdoors.
As they do not contain mercury, they light up in a few milliseconds and emits instantaneously the maximum degree of brightness. Do not produce, and therefore does not disperse, heat; do not generate any noise during operation.
Led lighting companies today increasingly produce the same shape as incandescent bulbs and standard attacks. These are models that can replace up to 60W light bulbs and energy saving equal to 80%.
In the coming years next to LEDs will OLEDs, light sources that produce diffuse light and not look like a light bulb, but a flexible thin sheet. Operate using the properties of specific organic substances, placed between 2 electrodes, glow in the passage of electric current.
Are employed in electronics, in displays, public lighting and increasingly also in domestic lighting. Are ideal for providing light at angles or diamonds and, thanks to its small size, can be integrated into kitchen and bath furniture.
