Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between the second lens and the LED is fixed, then the light pattern is stable and reliable, but the adaptability to different applications is poor
Solution Approach 1:
The patent applies the dynamics principle by making the distance between the second lens and the LED adjustable rather than fixed. The driving unit enables the second lens to move along the optical axis, dynamically changing the luminous angle and light pattern to adapt to different application scenarios while maintaining operational stability through controlled adjustment mechanisms.
Solution Approach 2:
The patent implements universality by designing a single lamp holder that can produce multiple light patterns (spotlight, floodlight, beam) through adjustable lens positioning. This multi-functional design allows the same device to serve different application needs without requiring multiple specialized lamp holders, thereby improving adaptability while managing structural complexity.
2Ease of operation
If the distance between the second lens and the LED is fixed, then the manufacturing process is simple, but the ease of operation for adjusting light patterns is poor
Solution Approach 1:
The patent applies mechanics substitution by replacing manual mechanical adjustment with an automated driving unit that controls the position of the second lens. This can be actuated by motors, voice coil actuators, or other automated mechanisms, allowing users to adjust light patterns through electrical signals or wireless control rather than manual manipulation, thereby improving ease of operation while accepting increased manufacturing complexity.
3Manufacturing precision
If the outer diameter of the light-incident portion is constant, then the manufacturing is easier, but the light pattern control precision is reduced
Solution Approach 1:
The patent applies local quality by varying the outer diameter of the light-incident portion at different axial positions rather than maintaining a constant diameter. This creates zones with different optical properties along the lens surface, enabling precise control over light pattern characteristics such as cutoff angles and intensity distribution, thereby improving manufacturing precision for light pattern control while accepting increased manufacturing complexity.

AI summary
A luminous system is disclosed. The luminous system is used for projecting light to a plane and includes a luminous component (18, 38) and an angle-adjustable device. The luminous component (18, 38) is used for generating the light ray. The angle-adjustable device is used for adjusting a luminous angle of the light ray. The angle-adjustable device is arranged between the plane and the luminous component (18, 38) and located on the route of the light ray. The angle-adjustable device comprises a first lens element (16, 36), and the first lens element (16, 36) comprises a light-emitting portion (162, 362) and a light-incident portion (160, 360) connected to the light-emitting portion (162, 362). The light-including portion (160, 360) comprises a recess (164, 3602) opposite to the light-emitting portion (162, 362). An outer diameter of the light-emitting portion (162, 362) is larger than an outer diameter of the light-incident portion (160, 360), and the outer diameter of the light-incident portion (360, 362) decreases along a direction away from the light-emitting portion (162, 362).
