Embodiment Construction
[0025] The used elements of the present invention are as follows:
[0026] Central aspherical lens: refracts the light near the main optical axis of the LED into a light parallel to the main optical axis.
[0027] Parabolic reflector: reflect the large-angle light emitted by the LED into parallel light.
[0028] Aspheric Microstructure Array: An array of dozens of square aspheric lenses refracts the light from the central aspheric lens and parabolic reflector to control the divergence angle of the outgoing light.
[0029] LED module group: LED modules with an optical system are grouped into a group and installed in a specific lamp, and the elevation angle of each group of LEDs is adjusted to finally obtain road illumination that meets the requirements of the national road lighting standard.
[0030] Instrument assembly process:
[0031] Assemble according to Figure 1, install the high-power LED on the bottom of the reflective cup, install the central aspheric collimating len...
