Document Type and Number:
WIPO Patent Application WO/2017/119712
Kind Code:
A1
Abstract:
Disclosed is a lighthouse lantern for a lighthouse using a laser diode and a fluorescent substance. The lighthouse lantern comprises: a power supply unit; a laser diode to which power is supplied from the power supply unit and which irradiates a laser in one direction; a fluorescent substance disposed on the line of travel of the laser and emitting light when the laser is incident; and a pair of reflectors that is a pair of reflectors having the fluorescent substance therebetween, wherein each reflector includes a reflective surface that is sloped in a direction deviating away from the fluorescent substance, and the reflective surfaces are disposed symmetrically and have the fluorescent substance therebetween. When such a lighthouse lantern is used, there are the advantages in that high output can be obtained using low power so as to improve power efficiency, the weakness of frequent breakdowns on the sea or near seawater can be improved upon, and manufacturing costs can be reduced.
