Strip light

The second method, phosphor converted LEDs (pcLEDs) uses one short wavelength LED (usually blue or ultraviolet) in combination with a phosphor, which absorbs a portion of the blue light and emits a broader spectrum of white light. (The mechanism is similar to the way a fluorescent lamp emits white light from a UV-illuminated phosphor.) The major advantage here is the low production cost, and high CRI (color rendering index), while the disadvantage is the inability to dynamically change the character of the light and the fact that phosphor conversion reduces the efficiency of the device.LED Ceiling Light The low cost and adequate performance makes it the most widely used technology for general lighting today.

Gallardo (7-2) retired 14 in a row at one point before allowing a single to Aubrey Huff in the seventh. San Francisco didn't have a runner in scoring position until two outs in the eighth.
Gallardo has been impressive most of this month.LED tube light In his past five starts beginning when he took a no-hitter into the eighth inning in St. Louis on May 7, he's allowed five runs to go 5-0 with a 1.26 ERA over that span.
Milwaukee took a 2-0 lead off Matt Cain (3-4) in the first off singles by Ryan Braun and Casey McGehee . Fielder drove in a run in the third and Rickie Weeks added a two-out, two-run double in the sixth.
Weeks and the rest of the Brewers say the improved starting pitching has helped the offense.
The biggest thing is just relaxing, really,LED flood light Weeks said. When you get three or four shutout innings right there, it gives your offense a chance to get up there and do some things that you want to do.
It was a disappointing series finale for San Francisco, which has lost four of five after a five-game winning streak. The Giants gave Cain no run support for the second straight outing.

In 1961, American experimenters Robert Biard and Gary Pittman working at Texas Instruments, found that GaAs emitted infrared radiation when electric current was applied and received the patent for the infrared LED.
The first practical visible-spectrum (red) LED was developed in 1962 by Nick Holonyak Jr., while working at General Electric Company.LED spot light Holonyak is seen as the father of the light-emitting diode. M. George Craford, a former graduate student of Holonyak, invented the first yellow LED and improved the brightness of red and red-orange LEDs by a factor of ten in 1972. In 1976, T.P. Pearsall created the first high-brightness, high efficiency LEDs for optical fiber telecommunications by inventing new semiconductor materials specifically adapted to optical fiber transmission wavelengths.

Until 1968,LED strip light visible and infrared LEDs were extremely costly, on the order of US $200 per unit, and so had little practical use.[16] The Monsanto Company was the first organization to mass-produce visible LEDs, using gallium arsenide phosphide in 1968 to produce red LEDs suitable for indicators.
