Chen is associated with Shenzhen Billda Technology Co., Ltd. and holds 2 patents.

Latest Patents

Chen’s latest patents describe control circuits that coordinate a mains supply, a battery, and light-emitting elements.

- **Light tube circuit for switching between emergency lighting and general lighting.** This circuit uses a main control module to determine whether mains power is available. When power is available, the module operates the light-emitting element in general lighting mode. During an outage, it switches to battery power to provide emergency lighting.

- **Downlight power box control circuit capable of realizing emergency lighting and general lighting.** This design connects a battery, a logic input module, and a light-emitting element to a main control module. When mains power is available, the light operates at 100% of its load power. During an outage, the battery supplies power, and the control module operates the light at 30%–50% of load power for emergency illumination.

Career Highlights

Chen’s disclosed inventions focus on practical power-management functions for lighting products. By distinguishing between normal mains operation and power outages, the circuits are designed to provide general lighting when possible and battery-powered emergency lighting when needed.
