Description

反射型透镜的发光管 Reflective arc tube lens

技术领域 FIELD

本实用新型涉及光电器件领域中的一种反射型透镜的发光管,特别适用于作大发散角度、高效率的发光二极管器件。 The present invention relates to the field of optoelectronic devices of the arc tube in a reflective type lens, particularly suitable for large divergence angle, high efficiency light emitting diode device.
