The optical pattern can change the angle of light rays contacting with the optical pattern, and the optical pattern can freely change the angle of the light rays after being arranged on the surface of at least one of the light receiving part 1, the first reflection part 2, the second reflection part 4 and the light emitting surface 6, so that the light rays formed by penetrating through the light emitting surface 6 form unique light shapes, and different light distribution requirements and lighting effects are met.
In some embodiments, the angle between the first reflective portion 2 and the collimated light is 45 °. After the parameters are adopted, the main light split and the side light split formed by receiving and reflecting the light by the first reflecting part 2 are approximately vertical to the collimated light, so that the overall standardized design of the light guide structure is facilitated, and the formed main scattered light and the side scattered light are easy to be emitted outwards in a way of being vertical to the light emitting surface 6.
Referring to fig. 1 and 2, for example, in an alternative implementation, referring to fig. 1 and 2, the light-absorbing portion 1 is a conventional light collector.

Wherein the distance value of the conventional condenser to the first reflecting part 2 can be arbitrarily changed according to the actual space.

The light-emitting component fully utilizes the energy lost by a light-receiving surface cut off by a traditional direct-type condenser to meet the modeling, collects the energy of a light source as much as possible, and then divides the energy into a plurality of beams to be deflected after passing through a first reflection part. After light emitted by the light source irradiates the surface of the light guide structure, the light is collimated and guided by the light guide structure and then can be emitted from the preset light emitting surface 6 to form a model, the light cannot be scattered outwards freely, and the energy of the light source can be utilized more effectively.
