Computer network control "smart" LED lights developed

According to foreign media reports, several large companies in the world have developed plans to produce smart LEDs, including Philips. The use of LED bulbs can significantly reduce the cost of use for homes and businesses. If a 10 watt LED bulb is used to replace all 60 watt incandescent lamps in the United States, the annual electricity bill can be as high as $3.9 billion. A new generation of intelligent LED lamp can also be connected to a local network which can communicate and smart phones or computers.

LED bulbs have a higher conversion efficiency of light energy than conventional incandescent lamps because more of the electrical energy is converted to light energy in the LEDs, rather than being converted to heat more in incandescent lamps. For most incandescent lamps, the power per watt can only emit 5-20 lumens of light, and fluorescent tubes can emit 40-70 lumens per watt, compared to 20-100 lumens per watt of LED bulbs.

People can use a mobile phone or computer to remotely control the brightness and color of the bulb, and even program the bulb for maximum energy savings, such as turning it off at a specific time of day. For people who travel a lot, you can also scare off potential thieves by turning the light bulb on or off.

Another advantage of LED bulbs is the ability to easily change the color temperature of the glow, producing a bright, soft light. It is also possible to arbitrarily change the color of the light by combining LED bulbs of different colors and adjusting the relative brightness between them.
