LED light emitting group

摘要

A LED light emitting group (1) apt to produce an outgoing light beam having its own optical axis (8) is equipped with a plurality of LEDs (18), distributed on a plate-shaped body (13) and having a fixed central plane portion (14) orthogonal to the optical axis (8) and a crown (13) of peripheral plane portions (16) tilted with respect to the central plane portion (14) and converging the one towards the other one and towards the central plane portion (14) and the optical axis (8); each one of said plane portions (14, 16) carrying a plurality of said LEDs (18).

1. Light emitting diode (LED) light emitting group comprising:
a plurality of LEDs configured to produce an outgoing light beam having an optical axis; a supporting element that supports said LEDs, wherein said supporting element comprises
a coupling base, anda first plate-shaped body carried by said coupling base and comprising a central plane portion orthogonal to said optical axis and a crown of peripheral plane portions tilted with respect to said central plane portion, wherein each of said peripheral plane portions converge toward at least one other peripheral plane portion of the crown, toward the central plane portion and toward said optical axis, wherein the central plane portion and each one of said peripheral plane portions carries a respective subset of the plurality of LEDs and wherein a respective hinge portion is interposed between said central plane portion and each one of said peripheral plane portions; and an actuator machine affixed to said first plate-shaped body and including a second plate-shaped body, wherein said second plate-shaped body is affixed to translating members at bases of the translating members, wherein each of the translating members is in contact with a different one of the peripheral plane portions at a respective contact area, and wherein said machine is configured to translate said second plate-shaped body such that said translating members move linearly and simultaneously at the respective contact areas and are constrained to rotate the respective peripheral plane portions around a respective hinge axis toward or away from said central plane portion such that a converging point of LED light beams from the peripheral plane portions varies along said optical axis.
