  • both LEDs may not be placed so close to the focus at the same time that light distribution with acceptable optical efficiency can be produced. Even more serious, however, is usually the influence of the out of focus placed LEDs on the homogeneity of the appearance of the lamp in the on state. Because the lighting functions are an essential design element represent in the motor vehicle, the illumination of a particular light exit surface should be as homogeneous as possible. When LEDs are out of focus, homogeneous illumination is usually no longer possible.
