Embodiment

[0018] Example: like Figure 1-3 As shown in the figure, an optical component of an LED navigation aid lamp for generating a rectangular spot includes a prism and a lens directly below it. Combined with several lens incident surfaces 7 at the bottom to form a lens exit surface 4, there are two adjacent prism exit surfaces 1 on the prism, and one of the prism exit surfaces 1 is provided with a curved surface and painted with a black coating It becomes the reflective surface 2 of the prism, the bottom of the prism is the incident surface 3 of the prism, and the incident surface 3 of the prism is parallel to the outgoing surface 4 of the lens on the upper part of the lens.

[0019] The distance d between the incident surface 3 of the prism and the lens exit surface 4 on the upper part of the lens is 17.2mm.

[0020] A lens threaded hole 5 and a downward-facing lens positioning bolt 6 are respectively provided at both ends of the lens.

[0021] The material of the lens is poly...

Abstract

The invention discloses an LED navaid lamp optical assembly used for generating rectangular spots. The LED navaid lamp optical assembly used for generating the rectangular spots comprises a prism and a lens under the prism. A plurality of lens incident planes which are mutually independent are arranged on the bottom surface of the lens. A curved surface is arranged at the upper portion of the lens and the curved surface combines with the lens indecent planes at the bottom of the lens together to form a lens exit plane. Two adjacent prism exit planes are arranged on the prism, wherein a curved surface is arranged on one prism exit plane, after a black coating film is painted on the prism exit plane, a prism reflecting plane is formed. A prism indecent plane is arranged at the bottom of the prism. The prism indecent plane and the lens exit plane at the upper portion of the lens are mutually parallel. The LED navaid lamp optical assembly used for generating the rectangular spots has the advantages that the lens and the prism are respectively provided with the curved surfaces, and the lens exit plane and the prism reflecting plane are formed respectively, an independent structure of a light scattering piece is eliminated, space is saved, matching with a navaid lamp, the rectangular spots which meet requirements can be generated by only two LEDs under the driving of small current, luminous efficiency is improved, power is reduced, and energy is remarkably saved.

Description

technical field [0001] The invention relates to an optical component, in particular to an optical component of an LED navigation light for generating a rectangular light spot. Background technique [0002] At present, traditional navigation lights use halogen tungsten lamps as light sources. Halogen tungsten lamps rely on color filters and lenses to control the color and angle of light, so that navigation aids can meet the requirements of international standards for luminosity and chromaticity characteristics. [0003] However, due to the use of tungsten-halogen lamps as the light source, traditional navigation lights have disadvantages such as short service life, low light efficiency, high energy consumption, complex structure, and high maintenance costs. With the continuous development of science and technology, it is gradually becoming possible to apply LEDs to the field of navigation lighting. LED has the advantages of long life, high luminous efficiency, low energy co...
