Solution Overview
Problem
Existing lighting fixtures with fixed lenses require replacement for different light emission effects, prolonging installation and necessitating multiple purchases, which adversely affects user experience.
Innovation Solution
A light emitting device with an adjustable optical angle, featuring a base, light source, and panel with movable components, allowing multiple transmission angles without replacing fixtures, and including a movable switching rod and fixed member for stable angle adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed lenses are used in lighting fixtures, then the structure is simple and stable, but multiple fixtures are needed for different light emission effects
Solution Approach 1:
The patent applies the dynamics principle by making the panel movable relative to the light source through a guiding groove and movable switching rod mechanism. This allows the transmission angle to be dynamically adjusted between different preset positions (first transmission areas for first angle, second transmission areas for second angle) without changing the overall fixture structure, thus achieving adaptability while maintaining structural simplicity.
Solution Approach 2:
The patent segments the transmission function by dividing the panel into different transmission areas (first transmission areas and second transmission areas) with different transmission angles. Each area can be selectively positioned in front of the light source through the movable mechanism, allowing different light emission effects to be achieved by selecting different segments, thereby providing versatility without requiring multiple complete fixtures.
2Adaptability or versatility
If multiple lighting fixtures with different transmission angles are purchased, then different light emission effects are achieved, but installation time increases and user experience deteriorates
Solution Approach 1:
The patent implements universality by designing a single lighting fixture that can perform multiple functions - specifically, it can emit light at different angles (first angle and second angle) by moving the panel to different positions. This multi-functional design eliminates the need for users to purchase and install multiple separate fixtures with different fixed angles, thereby reducing installation time and improving user experience while maintaining transmission angle variety.
3Adaptability or versatility
If the panel is made movable to enable angle adjustment, then multiple transmission angles are achieved, but the fixing stability may be compromised
Solution Approach 1:
The patent resolves the stability issue by implementing a dynamic system with preset positions - the panel can move along the guiding groove but is designed to be stably fixed at specific positions (first position and second position) corresponding to different transmission angles. The movable switching rod and elastic buckle mechanism ensure that once positioned, the panel remains securely fixed, thus achieving both angle switching capability and fixing stability.

AI summary
A light emitting device with an adjustable optical angle includes a base, a light source, and a panel. One of the light source or the panel is movably mounted on the base. The light source includes a plurality of light emitting matrices. The panel includes a plurality of first transmission areas. A distance between two adjacent light emitting matrices is equal to a distance between two adjacent first transmission areas. The panel includes one or more second transmission areas respectively disposed between the two adjacent first transmission areas. The plurality of first transmission areas and the one or more second transmission areas have different transmission angles. The one of the light source or the panel is configured to be moved to enable a light emitting area of the light source to be located to correspond to the plurality of first transmission areas or the one or more second transmission areas.
