Variable Light Distribution LED Lighting Device

The patent replaces mechanically adjustable reflectors with electronically controllable LED groups. Instead of using moving mechanical parts to change light distribution, the invention uses an electronic circuit to selectively activate different groups of LEDs, each with different beam characteristics. This substitution eliminates mechanical components, thereby improving reliability while maintaining the ability to adjust light distribution.

The patent divides the lighting system into multiple groups of LEDs, where each group can be controlled independently. By segmenting the light sources and controlling them separately through an electronic circuit, the system achieves variable light distribution without mechanical adjustment. This segmentation allows selective activation of specific LED groups to achieve desired lighting effects.

The patent replaces complex reflector arrangements with a simpler LED-based electronic control system. Instead of manufacturing and assembling elaborate reflector structures with multiple light sources, the invention uses standard LEDs with different beam characteristics that are controlled electronically. This approach significantly reduces manufacturing complexity and cost while achieving the same functional result of adjustable light distribution.

The patent achieves different light distributions by changing the operational parameters of the LED groups rather than using physically different reflector structures. By selectively activating LED groups with different beam characteristics (different angular distributions of light), the system achieves variable lighting effects without requiring complex mechanical or optical structures, thereby reducing manufacturing costs.
