Efficient and cost-effective LED bulbs that replicate the optical performance and appearance of incandescent bulbs through strategic mechanical and optical design. LEDs are arranged on multiple sides of the bulb to emit light in various directions, complemented by reflective surfaces and diffusers to disperse and soften the light. This configuration achieves a more omnidirectional, incandescent-like light pattern without the need for complex optics. The design also incorporates simplified construction and robotic assembly techniques, reducing costs and enhancing mass production efficiency compared to traditional LED bulb designs.
