Recently, the world has been crazy about LED lighting. If you don’t tell yourself about the energy-saving advantages of LED lights and their accessories, you can’t open professional magazines or home magazines. In fact, LEDs have come a long way since they first appeared in the mass market seven years ago.
LED technology (led lampor) is now a realistic replacement for light bulbs due to unprecedented levels of R&D investment, marketing from major companies such as Philips and Osram, and countless well-known brands made in China. Compact fluorescent and halogen lamps. .
The life of the lamp, the luminous power and the increasing importance of LED light efficiency have now become a step in the model a few years ago. If this is not the case, the precursors of these existing lamps usually make a completely unrealistic statement about the life of the lamp, indicating that inaccessible numbers, such as 70,000 hours, in some cases they do not match the performance of the bulb. The lamp is 1000 hours. ! This gave the LED a bad reputation, of course, causing the suspicions of the first users. Furthermore, the light output of the previous plurality of diode lamps is actually very low and can actually be used only as a form of accent lighting, such as space or walking for foot illumination, rather than lighting tasks. The quality of the first batch of prophets’ cold blue light further exacerbated this problem, which did not satisfy most people.
LED lights now offer significantly better shelf life because many big brands trade more than 30,000 hours. The quality of light has been fundamentally improved, although LEDs still have a certain “feel” that does not satisfy all tastes, but usually have different color temperatures, such as white, white cool white for most applications. The efficiency of light is another area where LEDs work better now. This is a measure of the lumens per watt and provides a more accurate picture of the luminaire performance, not just the wattage. Therefore, the 5W LED lamp five years ago will have a very different output than the 5w lamp. In the next few years, we will all get used to “every lumens per lumen” or light efficiency, but for now, for most domestic buyers, this is a strange concept.
LED is the perfect answer for all our prayers, right? … well, no. not yet. He has just read the way LEDs have gone, he did, but it is far from being able to adapt directly to halogen lamps. Here are some reasons:
The first is the price. The new generation of LED lights is not even on the same planet, let alone the parking ball, just like the price of halogen lamps. You can buy the Osram GU10 halogen lamp brand in the UK, and most lighting retailers are priced between £1.00 and £2.00. Brand LEDs equivalent to Osram or Philips will cost at least 25 euros. Of course, LEDs will save you money when considering energy and maintenance costs over the life of the lamp. But it is not easy to convince the homeowner to spend £250 on the kitchen light.
Size As mentioned above, the new generation of LED lights (led lampor) has better light output, but this is not meaningless. Bright, bright lights produce more heat. In order to dissipate heat, modern LED lamps require a larger heat sink, which means that the lamp itself can be more than twice as long as a halogen lamp. Quite simply, many LED lights are not suitable for existing fixtures, which means that homeowners need to replace existing fixtures to take advantage of LED lighting.
Darken now there is a minefield! LED dimming is difficult, and even models that claim to be “dimmable” are not suitable for most existing switches.
