A shelf lighting mechanism has a lamp arranged on the upper front of the shelf, the lamp has a light source and lens, the top of the lens has a concave space for accommodating the light source, a first irradiation part is formed on one side of the inner wall of the concave space, and the light emitting surface of the first irradiation part is arranged to guide light to irradiate the upper area of the shelf; the bottom and the other side of the inner wall of the concave space are formed with a second irradiation part, and the light emitting surface of the second irradiation part is arranged to guide the other part of the light from the light source to irradiate the lower area of the shelf. The upper and lower areas of the shelf can be illuminated simultaneously by one lamp.

A lens and an illumination method thereof relates to the field of illumination technologies. The lens is provided with a concave space for accommodating a light source, a first irradiation part is formed on a first side of an inner wall of the concave space, and second irradiation parts are formed on the bottom and a second side of the inner wall of the concave space; a main light beam emitted by the first irradiation part and a main light beam emitted by the second irradiation parts form an acute angle. By means of the present invention, an upper region and a lower region of a to-be-irradiated object can be illuminated through one light source at the same time, and the light source arrangement cost is reduced.

A multifunction lighting apparatus includes a light body, an adjustment bracket, and a frame. More than one optical unit may be selected to be installed to the multifunction lighting apparatus. In addition, the light body may be moved with respect to the adjustment bracket to provide more flexible light effect.

An aircraft exterior lighting multi-LED array for variable beam profile enables illumination of landing and taxi lights from a common fixture. An optic enables direction of luminance emitted from at least one central emitter (or cluster of emitters) along steradians illuminated when landing while directing luminance emitted from at least one peripheral emitter (or cluster of emitters) along steradians illuminated when taxiing.

The utility model discloses a projecting device for generating a light effect of a galactic starry sky, including: a light-emitting assembly including at least one first incoherent light source and at least one first condensing lens, the first condensing lens being arranged on an illuminating surface of the first incoherent light source; a film assembly including a film sheet provided with a galactic starry sky pattern, the film sheet being arranged on the other side of the first condensing lens relative to the first incoherent light source; and an imaging assembly including at least three lenses, the three lenses being an imaging lens, an adjusting lens, and a wide-angle lens arranged sequentially in a projection direction of the film sheet, respectively. The technical solution of the utility model effectively improves practicality of the projecting device by setting a plurality of functional lenses.
