While aperture lamps are similar in construction to internal reflector fluorescent lamps, the major difference is that an aperture reflector covers a larger portion of the circumference and has a clear window in the coating for the light to come through. This 30 or 60 degree clear glass opening is called the aperture and does not contain any phosphor. It concentrates the light in one direction in order to provide a higher intensity or brightness.
The reflective coating of an aperture lamp is 330 or 300 degrees and the phosphor coating covers just that area of the lamp. Since the intensity of the light increases with a decreasing aperture width, it is important to consider the size of the aperture surface. With our advanced precision technology, we can produce lamps with an aperture width as small as 2 millimeters wide.
While aperture lamps are used in applications such as scanners and imaging machines, a popular new use for aperture fluorescent lamps is for edge lighting in signs and displays. Since aperture lamps are inherently uniform along the lamp’s length, the smaller diameter lamps allow edge lit signs to be built efficiently and significantly brighter as well as slenderer. They also do not create annoying light bands.
