| 摘要 | A lighting device for emitting direct light and indirect light, includes a first transparent light panel comprising at least one organic light emitting device, the first transparent light panel emitting direct light and indirect light during operation thereof; and at least a second transparent light panel comprising at least one organic light emitting device, the second transparent light panel emitting direct light and indirect light during operation thereof, the second transparent light panel being positioned so that at least a portion of indirect light emitted from the first transparent light is transmitted through the second transparent light panel and at least a portion of direct light emitted from the second transparent light panel is transmitted through the first transparent light panel, wherein the first transparent light panel is controllable independently from the second transparent light panel to control a ratio of direct light to indirect light emitted by the lighting device. Other aspects are described and claimed. | ||

| 主权项 | 1. A lighting device for emitting direct light and indirect light, comprising: a first transparent light panel comprising at least one organic light emitting device, the first transparent light panel emitting direct light and indirect light during operation thereof; and at least a second transparent light panel comprising at least one organic light emitting device, the second transparent light panel emitting direct light and indirect light during operation thereof, the second transparent light panel being positioned so that at least a portion of indirect light emitted from the first transparent light is transmitted through the second transparent light panel and at least a portion of direct light emitted from the second transparent light panel is transmitted through the first transparent light panel, wherein the first transparent light panel is controllable independently from the second transparent light panel to control a ratio of direct light to indirect light emitted by the lighting device. | ||
