Beacon light optical device and working method thereof

Abstract

The invention relates to a beacon light optical device and a working method thereof, the beacon light optical device comprises a plurality of light-emitting units which are uniformly distributed along the circumference, and each light-emitting unit comprises two LED lamp beads with different colors and a rotary combined curved lens; the rotary combined curved lens comprises a lens body, and the lens body is of a semi-revolving body structure which is symmetrical up and down. The periphery of the lens body is provided with an annular refracting surface located in the middle and conical refracting surfaces located on the two sides of the annular refracting surface, the two ends of the lens body are provided with inwards-concave rotating parabolic reflecting surfaces, the conical refracting surfaces and the rotating parabolic reflecting surfaces form a delta wing structure, and the inner side of the lens body is provided with a lens cavity used for containing the LED lamp beads. The beacon light optical device integrates different colors of light, and the light emitting combination of the different colors of light can be controlled according to needs; the light-emitting range is a light-emitting area with the horizontal 360 degrees and the vertical small angle, and the deviation of the irradiation angle and direction of light beams emitted by the LED lamp beads of different colors can be reduced.

Description

technical field [0001] The invention relates to the technical field of beacon light optics, in particular to a beacon light optical device and a working method thereof. Background technique [0002] Navigation lights are a type of traffic lights installed on certain navigation marks to ensure safe navigation of ships at night. It emits light at night according to the specified light color and flash frequency, and its outgoing beam must reach the specified irradiation angle and visible distance. [0003] According to the type of light source used, the development of beacon lights has gone through several development stages: kerosene lamp beacon lights, incandescent beacon lights, light-emitting diode (LED) beacon lights, integrated light source solar integrated beacon lights, and solar integrated intelligent beacon lights. At present, light-emitting diodes (LEDs) are mostly used as light sources for navigation lights. [0004] According to the different platforms, the types...

Problems solved by technology

[0006] For different usage conditions, it is often necessary for the navigation lights to emit different colors of lights to give different navigation instructions, and the lights of different colors are made into independent lights, resulting in a waste of cost and resources; if multi-color LED lights are used Beads are used as a light source, because the light-emitting chip is spliced ​​by different color light-emitting chips. After the light of each color passes through the optical device, due to the different positions of the light-emitting chips of different colors, it will cause deviations in the irradiation angle and direction of the different colors of the outgoing beams. And this deviation will exceed the range required by the indicator
