The light-emitting semiconductor material determines the LED's color, so the number of colors is infinite. As indicated by its full name â Light Emitting Diode â an LED is a diode that emits light. A diode is a device that allows current to flow in only one direction. Almost any two conductive materials will form a diode when placed in contact with each other â with a single p-n semiconductor junction between them.
For other uses, see Texas Longhorn (disambiguation) and Longhorn (disambiguation). The Texas Longhorn is a breed of cattle known for its characteristic horns, which can extend to over 1.8 m (5.9 ft) tip to tip for bulls, and 2.1 m (6.9 ft) tip to tip for steers and exceptional cows.
Not all the successful Longhorn ranches are in Texas. Colorado also has its place in the history of the Texas Longhorn. We have a very successful Longhorn ranch in Colorado. The Searle Ranch is owned by Stan Searle, managed by Gary Lake, and located in Ellicott, which is 16 miles due east of Colorado Springs.
