摘要:
A device includes a light emitting assembly including at least one light panel including one or more phosphorescent organic light emitting devices. The device may, for example, be a personal lighting device. The at least one light panel has a peak luminance less than 5,000 cd/m2, an efficiency of greater than 30 lm/W, and a maximum surface temperature during illumination in ambient conditions of no greater than 40° C., At least a portion of the light emitting assembly is touch sensitive to provide control of the device.
