Marine led navigation lights

Abstract

The invention provides marine LED navigation lights which performs primary restriction on angle of light emitted from an LED through forming a shielding component by LED modules and performs secondary restriction on angle of the light emitted from the LED through forming a locking part at a housing, so that collision between ships can be prevented without breaking through International Regulations for Preventing Collisions at sea. Furthermore the invention provides the marine LED navigation lights which have advantages of high impact resistance, long service life, remarkable power and maintenance cost reduction and cost competitiveness improvement through replacing existing incandescent lamps by LEDs. The marine LED navigation lights provided by the invention comprise the components of: a housing which accepts a main board in the internal space; a plurality of LED modules which are arranged on a main substrate and is provided with a plurality of LEDs for emitting light; and a cover which covers the upper part of the housing, wherein the LED module comprises the following components: a heat radiating board which is internally provided with a central hole; LEDs which are formed outside the heat radiating board and are used for emitting light; and heat radiating fins which are formed in the central hole of the heat radiating board and are used for radiating heat transmitted from the LEDs.

Description

technical field [0001] The present invention relates to marine LED navigation lights. Specifically, the present invention relates to marine LED navigation lights that prevent the angle of light emitted from LEDs by constituting a light-shielding member in an LED module. The primary restriction is performed, and the second restriction is performed on the angle of light emitted from the LED by forming a locking part in the housing, so that collisions between ships can be prevented without violating the international maritime collision avoidance regulations. [0002] In addition, it relates to LED navigation lights for ships that use LEDs instead of conventional incandescent lamps, which have strong impact resistance, long life, reduced power consumption and maintenance costs, and improved cost competitiveness. Background technique [0003] Generally speaking, navigation lights for ships are set up to indicate their existence and direction of travel when the ship is sailing at ...

Problems solved by technology

[0009] However, conventional navigation lights for ships using incandescent light bulbs such as figure 2 As shown, the incandescent bulb 2 arranged in the closing part 1 of the housing is arranged in the central part of the closing part 1 of the housing, whereby the light irradiated from the incandescent bulb 2 can only be emitted from the The illuminating part 3 illuminates a limited open range, on the contrary, the marine LED navigation lights such as image 3 As shown, a plurality of LEDs 2 a , 2 b , 2 c , and 2 d are arranged on the outer wall of the heat-generating component 4 provided in the locking portion 1 of the casing. Therefore, among the lights irradiated from the LEDs ( 2 a to 2 d ), the ones arranged on the outer edge The LEDs 2a and 2d irradiate within the irradiation range from La to Lb within the range of the open irradiation portion 3, but for the LEDs 2b and 2c arranged in the center, the light is diffused and irradiated to La out of the irradiation range from La to Lb. From Lc to Lb and from Lb to Ld, there is a problem that the range of the irradiation angle of light deviates from the international rules for preventing collisions at sea
