Ultraviolet LED helicopter rotor lamp

Abstract

The invention discloses an ultraviolet LED helicopter rotor lamp, the lamp body comprises a fixed support and a main body shell capable of swinging relative to the fixed support, an ultraviolet LED module, a driving module and a filtering module are arranged at the bottom of the inner cavity of the main body shell, a reflection cup with a parabolic curved surface is arranged above the ultraviolet LED module, a glass sheet is arranged at the top end of the reflection cup, and a front cover fixed to the top end of the main body shell is arranged on the glass sheet. By use of the LED, the service life of the product can reach thousands of hours, so that the later maintenance cost is greatly reduced; green visible light is emitted in a manner of exciting the fluorescent coating through the ultraviolet rays, the warning effect is good, and the principle is ingenious; the lamp body can be fixed on the helicopter body, so that the problems of line loss and breakage are completely overcome, and the requirement on the airborne environment is better met, the mounting reliability is greatly improved; the light-emitting angle of the lamp body is adjustable, so that the optimal warning effect is ensured.

Description

technical field [0001] The invention belongs to the field of LED lighting, and in particular relates to an ultraviolet LED light source product that provides contour indication for helicopter rotors at night. Background technique [0002] The rotor light is an indispensable light source for indicating the outer contour of every helicopter. During the flight of the helicopter, a closed halo is formed on the propeller blade to serve as a warning. However, the installation method of the light source has always been a technical problem. The specific reasons are as follows : A, the installation method is not firm: when the helicopter is working, the propeller is in a high-speed rotation state, and the huge centrifugal force will cause the light source installed on the blade to break away from the body and be thrown out, thereby causing danger and injury. B. Line loss: Since the propeller is in a rotating state when the helicopter is working, the lead-out line will also rotate wit...

Problems solved by technology

[0002] The rotor light is an indispensable light source for indicating the outer contour of every helicopter. During the flight of the helicopter, a closed halo is formed on the propeller blade to serve as a warning. However, the installation method of the light source has always been a technical problem. The specific reasons are as follows : A. The installation method is not firm: when the helicopter is working, the propeller is in a high-speed rotation state, and the huge centrifugal force will cause the light source installed on the blade to break away from the body and be thrown out, causing danger and injury

B. Line loss: Since the propeller is in a rotating state when the helicopter is working, the lead-out line will also rotate with the light source on the propeller, so it will cause damage to the lead-out line and even break it, making it difficult to realize the function

C. Poor structural safety and reliability: If the light source is installed on the propeller, during the flight of the helicopter, the light source that rotates with the propeller blades is easily damaged under high-speed rotation, which reduces its reliability and affects its life

[0003] To sum up, the lighting method of installing the light source on the propeller blade of the helicopter not only wastes precious onboard energy, but also the installation method is not firm, the life is short, the later maintenance is cumbersome, and the structural safety and reliability are not high
