Abstract

The invention is applicable to the field of optical design, which provides a reflective cup and a runway alarm lamp. The reflective cup comprises a cup body, wherein the cup body comprises a cone-shaped first cup body and a cone-shaped second cup body which are mutually butted; the included angle formed by a generating line of the first cup body and a central axis of the reflective cup is larger than that formed by the second cup body and the central axis; the first cup body and the second cup body are respectively provided with a first reflecting surface and a second reflecting surface; and the first reflecting surface and the second reflecting surface are respectively formed by sequentially and adjacently connecting a plurality of first sub-reflecting surfaces and a plurality of second sub-reflecting surfaces around the central axis. The reflective cup can effectively tighten light beams, so as to ensure that light can be emitted at a proper angle and the light loss is reduced; and the reflecting surfaces of the reflective cup comprise a plurality of sub-reflecting surfaces, so that sufficient light mixing treatment can be performed, and uniform light emitting is realized. The runway alarm lamp adopting the reflective cup can effectively improve the utility rate of luminous energy on the basis that the lighting demand of the runway alarm lamp is satisfied, and facilitates energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the field of optical design, in particular to a reflective cup and a runway warning light including the reflective cup. Background technique [0002] At present, the reflective surfaces of the reflective cups used in airport runway warning lights are all arc-shaped, and the reflective surfaces are usually frosted to increase the diffuse reflection of the reflective surfaces and achieve the purpose of adjusting the exit angle and uniformity. However, this kind of reflective cup is not ideal for light adjustment, and more light will be emitted at a large exit angle and cannot be used, or light energy will be lost due to multiple reflections and diffuse reflections, resulting in the utilization of light energy of the reflective cup. The rate is low, which is not conducive to energy saving and environmental protection. Contents of the invention [0003] The object of the present invention is to provide a reflective cup, aiming t...
