Problems solved by technology

[0003] However, this type of matrix light group has many disadvantages: 1. The lamp beads are tightly arranged, the energy density is high, and the heat generated per unit is large, which shortens the service life of the light source; 2. The light source emitted by the lamp beads needs to be guided into the light guide column. On the medium intersection surface, the light loss is large and the utilization rate is not high; 3. Using the light guide column to guide the light, different beams generated by a single light source travel on different paths, resulting in the final beams emitted from the light guide column due to their different optical paths. Dispersion occurs, and the final irradiated light area is easily distorted, and the overall effect is not good.

Abstract

The invention discloses a controllable surface light source based on an equal optical path. The controllable surface light source comprises a lens and a plurality of light source units positioned behind the lens; each light source unit comprises a luminous body and a reflecting cup used for reflecting light rays emitted by the luminous body; the reflecting cup is provided with a virtual rotating shaft; the reflecting cup is cut by any construction plane which passes through the virtual rotating shaft, and the intersection line of the reflecting cup can reflect the light rays emitted by the luminous body in the construction plane at the equal optical path; the intersection line is cut from the configuration ellipse; and the luminous body is arranged on the virtual rotating shaft and coincides with the focus of each configuration ellipse. The surface light source has the characteristics of clear imaging, no chromatic dispersion, excellent lighting effect, complete overall function and strong practicability.

Description

Technical field [0001] The invention relates to a light source, and more specifically, it relates to a controllable surface light source based on an equal optical path. Background technique [0002] A matrix lamp group has already appeared on the market. A number of LED lamp beads distributed in a rectangular array are used as the light source inside, and they are closely arranged. Then a light guide rod is set directly in front of each light source to converge the light into one On the virtual light-emitting surface, the upper and lower adjacent edges and the left and right adjacent edges overlap between each point light source, resulting in a rectangular combined light source, which is enlarged and emitted by the lens to achieve a rectangular light-emitting area. [0003] However, this type of matrix lamp group has many disadvantages: 1. The lamp beads are arranged closely, the energy density is large, and the unit heat is large, which shortens the service life of the light sourc...
