Everyday light. A beginning.
LumaHarvest Technology Limited focuses on indoor light energy harvesting: turning light already present indoors into usable electrical energy and integrating it into warm, practical everyday products. Our focus is indoor-light-powered product design, rather than rooftop solar generation.
LumaViva: our first application
LumaViva 萤晞｜伴醒灯 brings OPV harvesting, rechargeable capacitor storage, motion sensing and warm lighting into a companion night light. The intention is simple: gather suitable light during the day and make stored energy useful after dark. More indoor-light-powered products are planned.
The practical design challenge
A night light needs energy when its surroundings are dark, while its harvesting surface needs light to replenish that energy. Our application combines collection, storage and a short motion-triggered load. Placement and actual activity remain part of the energy budget.
Our role and the OPV technology
LumaHarvest develops the finished-product integration. Chasing Light supplies the OPV technology described on this website. A module supplier’s technology recognition should not be understood as certification or an award for the complete LumaViva lamp.
What this case does and does not establish
LumaViva is our own product application, not an independent customer endorsement. Product illustrations show design intent and are labelled accordingly.
