Abstract
The utility model discloses a light-emitting device of a marine indicator light. The light-emitting device of the marine indicator light comprises LED light bars, a PMMA light guide plate, a reflecting film, a light box body and a PC diffusion plate. The light box body is in a cuboid shape. The PC diffusion plate is mounted on the upper portion of the light box body, the PMMA light guide plate is mounted in the middle part of the light box body, and the reflecting film is arranged at the bottom of the light box body. The number of the LED light bars is two, the LED light bars are arranged on the left side and the right side of the light box body respectively, and the LED light bars are bonded on the light box body through LED heat conducting double-faced adhesive tape. The bottom face and the side face of the light box body are respectively provided with a rectangular groove, and the rectangular grooves are used for clamping the PC diffusion plate and the LED light bars. The light-emitting device of the marine indicator light is simple in structure, there is no need to use silica gel for sealing, assembling is simple and reliable, assembling quality is good, and time is saved. The LED light bars cannot be potted through glue, instead, the LED heat conducting double-faced adhesive tape is used for bonding and fixing, bonding is convenient and fast, adhesion is good, and the heat conducting property is high and stable. The PC diffusion plate is additionally arranged, so that a protective effect is achieved on components, service life is prolonged, and light sources are more attractive and uniform.
