LED Lights in the Home

As the development of LED technology continues the LED manufacturers have achieved the magical 100 lumens per watt of light output for the LED making it “suitable” for use in domestic lighting applications. In these days of high energy costs it is important that we all try to save energy and one way of achieving this is the use of high output, low energy consumption LED lights.

The main features of LEDs when used in lighting are that the minimum amount of electrical power is used to create the maximum light output and the minimum amount of heat. Conventional lamps use a lot of power to create light and heat at the same time. With LEDs there is no ultra violet (UV), infra red (IR) and minimal forward projected heat. Compare this to the 35W halogen lamp pushing out around 500-600 lumens of light and vast amounts of forward heat, you would not want to touch one whereas an equivalent in LED may use around 8 watts of electrical power which gives a considerable saving on energy consumed. How many times have you been in a shop that has hundreds of halogen lamps for display purposes giving out masses of heat and the staff have the air conditioning at maximum to get rid of the heat in the shop. The use of LEDs would significantly reduce the amount of energy consumed and also reduce the need for the air conditioning to be up at high levels giving another saving in energy consumption. There are savings to be made both in the commercial and domestic environments. webcam 1080p B08CD9979P

When I first became involved with LED lighting in 2001, the light output of the LED in cool white was around 20 lumen per watt and as stated above it has now reached 100 lumen per watt in cool white. The range of white LEDs available now includes cool, neutral and warm white with colour temperatures ranging from 2700 to 8000+ k giving significant options for use in domestic application such as kitchens. The use of RGB (Red, Green, Blue) colour changing LED light units also enables the use of mood lighting in other living areas such as TV rooms, home cinema rooms and bedrooms.

The range of LEDs on the market include small surface mount componets operating at 20mA through to high output LEDs such as Luxeon or Cree operating from 350 to around 2000A. These units are usually operating in the region of 1 to 3 watts per LED. The sums are fairly simple at 1W the LED in cool white gives out approximately 100 lumens of light and the use of multiple LEDs in light units makes high lumen output units available to compare with 35 or 50W halogen units which we see in everyday use.
