Can be dressed up by the IPL home appliances light-emitting diodes (LEDs). Red, yellow, green, blue, white, LED ushered in the era of do not have to care about the price and free to use.
High Power LED 50W manufacturers said, "Now, red and yellow LEDs, the Taiwan side 'are a bunch of how much money' operator are cheaper than the bean sprouts." LED usage around the world is very large, consumption is increasing .
White with blue LED also began to receive the impact of this momentum. Into neither unattainable nothing special. The first is the blue LED prices began the rapid collapse of Note 1).
Note 1) blue LED, began a sharp decline in prices from 2002. The reason is that an increased supply. There are two reasons for the increase of supply. Nichia Chemical Industries (1) September 17, 2002 Day and Toyoda Gosei reached reconciliation, terminal manufacturers to use one of the blue LED, and do not have to worry about would be subjected to prosecution of the other party, (2) Career and Taiwan and China on optoelectronics and other manufacturers have developed a blue LED and start delivery.
A developer of mobile phone manufacturers exclaimed: "Ah, the blue led power a lot cheaper. 3,4 years ago, a few hundred yen, now takes only tens of yen". Said that the use of the LCD panel backlight blue LED module prices in the past few years dropped to 1/10. As for the cheap blue LED lights, Europe and the United States and Taiwan even 10 yen (8 cents) for sale Price Note 2).
Note 2) LED brightness, color performance and life of the higher price is more expensive. Inexpensive LED is generally made of shells shape is known as "shell-shaped LED, in most cases lower the brightness and other parameters.
Blue led 100w prices up to several hundred yen era, black and white LCD panel only issued to the blue light will be able to highlight high-grade sense of this phone is also a user object of envy.
With the changing times, and now the price of the blue LED is less than tens of yen.

Affected, even the original price of the most high-end white led power 10w has begun to gradually decline. Mixed in the red light, green light, blue light, or you can get white light in the blue LED phosphor materials. The blue LED is the cheaper, the lower the price of the white LED.
With the LCD panel to the color of propulsion, the vast majority of mobile phones will use white LED backlight. 2002, the unit price of the white LED has dropped to 80 yen was expected in 2005 will fall to 50 yen. Overseas, the phone's color screen speed to accelerate, but there are a lot of the manufacturers of white LED business, consider these factors, perhaps the price will decline at a faster rate "(Mizuho Securities).
In this way, the led 30w will usher in a can be any color, do not have to care about the price and the era of large-scale use. As if, in order to reflect this point, can see everywhere that product using the LED? "," This is the LED? "And so on.
