Description

Technical Field

[0001] The present application relates to the technical field of LED lighting, and in particular to an LED lighting optical system replacing a xenon flash lamp. Background Art

[0002] With the rapid development of the intelligent transportation industry and smart cities, there is a growing demand for monitoring fill lighting in intelligent transportation checkpoints during the day, especially for monitoring of cab personnel and face recognition. In addition, because the sunlight at noon is very strong, reaching up to 100,000 lux, ordinary light fill lighting cannot meet the requirements at all, and the camera cannot clearly capture the situation in the cab. Therefore, a high-brightness flash is needed to fill in the lighting for taking pictures of the cab.

[0003] However, the existing maintenance cost is high and the maintenance construction is complicated. Utility Model Content

[0008] The parabolic reflecting surface is fixedly mounted on the light source mounting base.

[0009] Furthermore, the LED light source is arranged on an aluminum substrate, and the aluminum substrate is arranged on a light source mounting base.

[0010] Furthermore, a spiral xenon lamp tube and a spherical reflecting surface are fixedly mounted on the parabolic reflecting surface.

[0011] Furthermore, the light source mounting base is a hexagonal prism with a regular hexagonal cross section, and the aluminum substrate is locked on each surface of the light source mounting base through heat conductive glue or graphite gaskets.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] A light source mounting base 5, on which an LED light source 6 is disposed;

[0025] The parabolic reflecting surface 1 is fixedly mounted on the light source mounting base 5 .

[0026] Specifically, the LED light source 6 is arranged on an aluminum substrate, and the aluminum substrate is arranged on the light source mounting base 5 .

[0027] Specifically, the parabolic reflecting surface 1 is fixedly mounted with a spiral xenon lamp tube 2 and a spherical reflecting surface 3 .

[0028] Specifically, the light source mounting base 5 is a hexagonal prism with a regular hexagonal cross section, and the aluminum substrate is locked on each surface of the light source mounting base 5 by means of thermal conductive glue or graphite gaskets.

[0029] The implementation principle of an LED lighting optical system that replaces a xenon flash lamp in an embodiment of the present application is as follows: the focus 4 of the parabolic reflective surface 1 coincides with the center of the spherical reflective surface 33, and the spiral xenon lamp 2 is placed on the focus 4 of the parabolic reflective surface 1 (the center of the spherical reflective surface 33), so that a part of the light emitted by the spiral xenon lamp 2 directly passes through the first reflection of the parabolic reflective surface 1, and is emitted along the positive direction of the Z axis to reach the illuminated surface, and the other part passes through the first reflection of the spherical reflective surface 33 to reach the parabolic reflective surface 1, and is emitted along the positive direction of the Z axis after the second reflection, so that basically more than 90% of the light passes through the reflection collimation effect of the parabolic reflective surface 1, which greatly improves the efficiency of the optical system and the emission angle is also very small;
