LED-lighting – lighting technology 2.0 is. In terms of economy and efficiency LED are far superior to other light sources. But not every one of the changeover is still convinced. It is, because confuse the many information on the package or because it was so far but actually always quite happy with his old lamps.
As LED dealers we are of one or another maybe not the most independent in the eyes, when it comes to the pros of LED lighting.Therefore, we are now neutral experts come to Word. The Association of German engineers (VDI) has released a brochure with consumer tips around the LED lighting, whose key points listofledlights would like to introduce to you in this article.
Electricity costs up to five times
What category are you – those who persuaded by hard facts, or those for which moral considerations play a role? Maybe you want to but not also in detail to worry, next to so many issues, that daily demand us a decision, to your lighting. No matter. LED lighting offers something for everyone. We stay with our list and start with the facts.
The important thing is the power consumptionfor the most, because electricity costs money.If you replace your incandescent or halogen lamps with LED lamps, you can your lower power consumption five timessince LED can get much more light output from the absorbed energy.Common LED emit 120 lm/W. Thus, they surpass all other white light suppliers in terms of efficiency. Under laboratory conditions, they come even on a light yield between 180 to 220 lm/W. That’s nearly the theoretically maximum possible efficiency value: 238 lm/w all of the input energy is converted into light.
LED lamps and electricity consumption: A calculation example
A 12-volt halogen lamp costs about 6 euro. It reaches 320 lumens with a 20W power consumption. An LED Retrofit costs about 15 euro and comes with 10 Watts to 820 lumens brightness.
A LED is almost as bright as three halogen lamps (960 lm). In addition, that the halogen lamps give up the ghost after 2,000 hours. LED for home users are, however, easily on a lifetime of15,000 to 35,000 hours of operation and work longer than any other light source. Because after all, comparatively short 15,000 hours in private homes during normal use of 15 years. In the professional area, for example for street lighting, even well above 50,000 hours of operation are in there. Even frequent on and turn off doesn’t hurt the reaching immediately after switching the full brightness.
So long, lights usually average in the budget:
In a lifetime of 35,000 hours and a standard electricity prices by 30 cents / kWh, the LED in our example would thus consume power for three euros in the first 1,000 hours of operation. The three halogen lamps, however, power for 18 euros. Their low consumption and long life make long term LED lamps so even a very favourable light. And: LED are always cheaper.
LED: Environment and health
An important advantage of LEDs is their eco-friendliness. It is with them while electronic components that must be disposed of separately alone for recycling reasons. However, LED bulbs contain no toxic mercury or other heavy metals.Important for all living children or pets consumers, which environmental protection is a matter of the heart and a point of safety for everyone in their household. LED light has No share of UV, which may cause eye or skin damage, or attract insects in the open air and die in Garden lamps.
LED: Lighting for the eye
After the facts are clear now we come to the aesthetic aspects, because here too convince LED all along the line. Who like to decorated house and yard and works, will be happy with these lamps. Because they are one more than lukewarm and the other very small LED lamps can be operated with manifold? Such as indirect lighting, furniture, stairs and sloping wall panel or design element. LED lighting enjoys because of the variety of shapes and colors available (RGB-LED) designers and architects of great popularity.
It is only important to know the most LED to only targeted emit its light in certain directions. So there are less losses on the one hand, on the other hand you must selectangle and beam direction of course then matched to the specific lighting task. That would be for a ceiling fixture with horizontal version about LED lamps, which emit the light side.
Appropriate colour and brightness control
Many LED bulbs are dimmable today available. With RGB controllers or even by app the brightness and intensity of the light can be on several models at your fingertips control so that you have about the appropriate lighting in every situation – according to mood and atmosphere. By selecting a specific color temperature, the light effect can be a LED also determine – from cosy warm white to cool, concentration-promotional Daylight White. Important for an optimal environment of light: the light sources in the room should have all the same color temperature.
By the way, the brightness of an LED is specified inlumens . While incandescent bulbs equally bright namely with the same energy consumption (Watts indication) energy consumption with LED lamps and little brightness were, so providing Watts of brightness equal, says. What LED you to, replace what light bulb to come on the same brightness, the table shows limks.
Retrofits Yes or no?
Dimmer then a cheap option if you want to keep your lamps and angle as direction fit retrofits sin. With an LED lamp, LED bulbs are still more efficient, because the system is optimally played. Check before buying the best always is how much space in the lamp for the light source, because LED bulbs can be sometimes slightly larger because of the electronic ballast as light bulbs.
I use energy saving light bulbs. Also replaced?
To replace energy-saving lamps with LED is first and foremost a sense, if they are defective.You can improve but also the colour reproduction through an Exchange or shorten the time.Who would like to do without mercury-containing light bulbs, is also well advised with a transition.
Better to gradually replace old lamps or better all at once?
For a homogeneous light, it is better to switch all lamps. Buy only the LED lamps, you just need to because the technique developed first ever and second LED lamps be continuously cheaper. Therefore, it may be also that are already other LED models in the trading, in half a year, and you no longer get “Your” LED. Also for this reason, you should use a model for a room and replace all at the same time.
