Abstract

The invention provides a light-emitting diode illuminating equipment, including N diode light-emitting apparatuses and N optical devices, wherein N is a natural number. Each of the optical devices includes a lens. Each of the optical devices corresponds to one of the diode light-emitting apparatus, for modulating a light pattern of the corresponding diode light-emitting apparatus. In an embodiment, the lens of each of the optical devices is a cat'"'"'s-eye-like lens. The lens includes a surface, where a groove is formed along an ellipse minor axis of the lens, such that the light transmitted through the lens can form a light pattern for a specific request.
