It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1

Referring to fig. 1, 2 and 3, the present embodiment provides a coaxial light emitting device based on conic optical properties, which can be used as a light source device in an exposure or anti-corrosion experiment, and can generate light similar to natural light, thereby simulating the illumination process of the natural light. The coaxial light emitting device comprises a frame, a reflecting plate 2, a positioning mechanism and a lamp tube, and in the embodiment, the device further comprises a polarizing glass 5, a bracket 13, a cushion block 25, a handle 26, a handle 9, a gasket 10, a pin hole block 12 and a mounting assembly.

The plate body located on the top of the frame 1 is a top frame 8. The first side plate 3 and the second side plate 4 are arranged in a mirror image mode, and the other part of the plate body can be arranged between the first side plate 3 and the second side plate 4 in a shutter mode. Because the frame 1 is designed into the shutter structure, the purpose of heat dissipation can be achieved, and therefore when the light source emits light, heat generated by the light source can be dissipated, the light source can be used for a long time, and the service life of the device is prolonged.

Referring to fig. 4, the reflection plate 2 has a parabolic cylinder 15 and two reflection planes 16, and the two reflection planes 16 are located at opposite sides of the parabolic cylinder 15. A portion of the light emitted from the light source located at the focal point of the parabolic cylinder 15 can be reflected on the parabolic cylinder 15 as a first parallel on-axis line, and another portion of the light can be reflected on the reflection plane 16 as a second parallel on-axis line. The linear coaxial light ray I and the linear coaxial light ray are combined into linear coaxial light. The parabolic cylinder 15 is actually a parabolic concave surface cut out from the reflector 2, and the reflective surface is oxidized to ensure reflectivity, so that more light is reflected from the parabolic cylinder 15. In this embodiment, the reflector 2 is made of an aluminum plate with a thickness of 1.5mm by laser processing, the parabolic cylinder 15 is cut out, and then the reflector 2 is bent by a sheet metal processing technique, that is, the reflector 2 has an arc-shaped bent structure.

Referring to fig. 5, the bracket 13 is installed on the frame 1 and has an arc-shaped installation groove. The reflecting plate 2 is embedded in the mounting groove, so that the mounting and fixing of the reflecting plate 2 are realized. The bracket 13 may be mounted on the frame 1 by means of bolts or the like, and the mouth of the bracket 13 is disposed toward the top of the frame 1, i.e., the light reflected by the reflection plate 2 will eventually exit through the frame mouth of the top frame 8.

The fixed hasp 19 is movably arranged on the fixed block 18 and can limit the rotation of the clamping block 17 when the clamping block 17 rotates to enable the first limiting groove and the second limiting groove to be combined into a limiting space. Since the first disk 20 of the positioning mechanism can change its position in the frame 1 by moving and the second disk 21 can rotate relative to the first disk 20, the light source locked by the locking assembly can change its position in the frame 1, so that the central axis can coincide with the focal line of the parabolic cylinder.

The end part of the lamp tube is limited in the limiting space. The lamp tube is changed in position in the top frame 8 by the first disk 20 and the second disk 21 so that the central axis of the lamp tube can coincide with the focal line of the parabolic cylinder 15.
