Title:
LAMP
Document Type and Number:
WIPO Patent Application WO/2019/154007
Kind Code:
A1
Abstract:
A lamp, comprising a light source (1101) including at least one light emitting point (S0); and a light receiving device located between the light source (1101) and the optical path of a collimating optical element (1104, 3104), the light receiving device at least comprising two light guides (1102, 1103, 3302), for respectively collecting light beams (1301, 1303, 3301, 3303) emitted at different angles from the light emitting point (S0) of the light source (1101), and respectively directing the collected light beams (1301, 1303, 3301, 3303) to the collimating optical element (1104, 3104) in a reflective or refractive manner, after which the light beams forming parallel light after the collimation of the collimating optical element (1104, 3104); and further comprising a mirror array (1105, 3105) for reflecting the parallel light to form a reflected light spot array. By means of the light guides (1102, 1103, 3302) of the light receiving device, at least two light beams (1301, 1303, 3301, 3303) at different angles emitted from the light emitting point (S0) can be projected to the collimating optical element (1104, 3104) and form parallel light beams respectively. This is equivalent to the light emitting point (S0) becoming at least two equivalent virtual light emitting points (S1, S2), after which the number of small light spots formed after reflection of the mirror array (1105, 3105) is at least doubled, so that the decoration effect can be improved.
