Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an optical device for an illuminated sidewalk according to the present invention. 3 fig. 3 2 3 is 3 a 3 schematic 3 sectional 3 view 3 taken 3 along 3 the 3 line 3 a 3- 3 a 3 in 3 fig. 3 1 3. 3 The illuminated sidewalk optical apparatus 10 is used for illuminating a sidewalk 30 in a predetermined area on a bottom surface. The illuminated sidewalk optical apparatus includes a housing 11, a light emitting module 12 disposed at one end of the housing 11, a first lens 13 disposed at the other end of the housing 11, and a second lens 14 disposed inside the housing 11 and between the light emitting module 12 and the first lens 13. The illuminated walkway optical installation also includes other functional modules such as mounting assemblies, power supply assemblies, connection assemblies, etc., which are well known to those skilled in the art and therefore will not be described in detail herein.

The housing 11 is made of an aluminum alloy material, and the housing 11 is used for mounting the light emitting assembly 12, the first lens 13 and the second lens 14. In this embodiment, the housing 11 is a cylindrical structure, and has two openings 110 at two ends, so that the cylindrical structure and the openings at two ends facilitate the installation of other components and save materials.

The light emitting assembly 12 includes a PCB board 121 fixed on the inner wall of the housing 11, and a light source 122 disposed on the PCB board 121 and facing the first lens 13. The light source 122 is a light source that can be used for illumination, such as an LED light source. The light source 122 is located on the central axis of the housing 11, so that the light efficiency is better. The PCB board 121 is a prior art, which is an electronic component, and thus will not be described in detail herein.

The first lens 13 is composed of a plurality of plano-convex lenses 130, and the convex surfaces of the plano-convex lenses 130 are arranged away from the second lens 14. The first lens 13 is used for refracting the light refracted by the second lens 14, so that the light 20 fills the preset area, and a bright area is formed in the preset area to illuminate the sidewalk 30.
