銆�銆�Abstract: The < color=#0000ff>LED Display is usually used in the situation of head-up watching. The luminous intensity distribution in the upward 50% power angle is wasted. This paper presents a new asymmetric LAMP design concept that part of the luminous intensity in the upward 50% power angle can be transformed to the downward. After implementing the new design, the upward 50% power angle is reduced to 20掳and the downward 50% power angle is increased to 40掳.

銆�銆�The luminous intensity of asymmetric LAMP in the downward 50% power angle increase 30% than the common LAMP. At the same time, the consistency of the light-matching also improved significantly, and the color bias of the display can be decreased.
