.. of the VLED over a wide range without regard to the characteristics of a particular FET or VLED, which may be of any color or wavelength. These values also show that the V F of a single white VLED is insufficient to allow the ...
.. stage in the manufacture of an RGB sensor is the tuning process, for which we will need an RGB light source based on power color LEDs, the current through which is regulated over a wide range. To obtain correct and stable results during the ...
.. LEDs find wide use in backlighting color-LCD screens in most portable devices, such as cellular phones, PDAs, and MP3 players. Multiple LEDs often ...
.. systems often use LEDs of different colors and in varying quantities of each color. Some examples are white for the display backlight, green for keypad illumination, and red for power. ...
.. it turns off, inductor L 1 discharges its stored energy through the LED during flyback, allowing you to light any type or color of LED. Figure 1. This simple astable multivibrator provides a low-cost way to drive an LED from a single cell. ...
.. they were not in full darkness. The circuit in Figure 1 lets you set a hue of blue light that can match your favorite blue color. Although you can accomplish this task with another circuit (Reference 1), this circuit provides a finer ...
