Deck prism natural lighting device

Abstract

A triple prism natural lighting apparatus for a deck comprises a triple prism piece, a prism fixing pedestal and a square pipe. The triple prism piece is arranged to the prism fixing pedestal, and two emergent surfaces of the triple prism piece penetrate a lower end of the prism fixing pedestal. A first opening and a second opening at two ends of the square pipe are connected to form a square through groove. The end where the first opening is located is fixedly connected to the lower end of the prism fixing pedestal. At least two opposite inner walls of the square through groove are equipped with reflectors. Natural light is absorbed above the deck by the triple prism piece of the triple prism natural lighting apparatus for the deck, the natural light emitted from the triple prism piece is multiply reflected by the reflectors, and finally the natural light having large illumination angles reaches an accommodation below the deck. According to the triple prism natural lighting apparatus for the deck, on the premise that the Maritime Labor Convention is satisfied, reduction of effective usable areas of the deck can be effectively decreased, and water tightness of the triple prism natural lighting apparatus for the deck can be effectively ensured.

Description

technical field [0001] The invention relates to a lighting device for ships, in particular to a deck triangular prism natural lighting device. Background technique [0002] Since the International Maritime Labor Convention imposes mandatory requirements on the natural lighting of the living quarters on ships, the layout of the living quarters of ships with a small gross tonnage is subject to the constraints of the International Maritime Labor Convention and faces a great test. [0003] The living quarters of existing ships are mostly arranged under the open-air freeboard deck at the bow, and only fluorescent lamps are installed indoors. Since the side is a collision-prone point, dense rubber fenders are installed on the side, so it is not suitable for setting natural Lighting device; if a glass skylight is set on the deck, the glass skylight occupies most of the deck area to obtain enough light, and at the same time, the glass skylight has perspective, and the privacy of the...

Since the side is a collision-prone point, dense rubber fenders are installed on the side, so it is not suitable for setting natural Lighting device; if a glass skylight is set on the deck, the glass skylight occupies most of the deck area to obtain enough light, and the glass skylight has perspective, so it is difficult to guarantee the privacy of the living cabin
