Abstract

The invention discloses a light-emitting diode illuminating equipment, including a heat-dissipating plate device, a plurality of heat-conducting devices, a plurality of diode light-emitting apparatuses, a plurality of optical devices, and a hollow barrel. The hollow barrel is engaged to the heat-dissipating plate device to form a space for accommodating the heat-conducting devices, the diode light-emitting apparatuses, and the optical devices. Each of the diode light-emitting apparatuses corresponds to one of the heat-conducting devices. Each of the optical devices corresponds to at least one of the diode light-emitting apparatuses and modulates a light pattern of the corresponding diode light-emitting apparatus. In an embodiment, each of the optical devices includes a cat'"'"'s-eye-like lens. The cat'"'"'s-eye-like 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.
