摘要： A light-guide type light-emitting device includes a heat-dissipating unit, a conductive unit, a light-emitting unit and a light-guiding unit. The heat-dissipating unit includes at least one heat-dissipating body. The conductive unit is disposed on a first side of the heat-dissipating body. The light-emitting unit is disposed on a second side of the heat-dissipating body, and the light-emitting unit includes a plurality of light-emitting elements electrically connected to the conductive unit. The light-guiding unit includes at least one light-guiding element disposed on the light-emitting unit for receiving light beams generated by the light-emitting unit, and the light-guiding element has a plurality of micro light-guiding structures formed on the outer surface thereof. Hence, the instant disclosure can not only mate the light-emitting unit with the light-guiding unit to solve glaring problem as a result of using LED, but also provides a wider light-emitting range.

摘要翻译： 导光型发光装置包括散热单元，导电单元，发光单元和导光单元。 散热单元包括至少一个散热体。 导电单元设置在散热体的第一侧。 发光单元设置在散热体的第二侧，发光单元包括与导电单元电连接的多个发光元件。 导光单元包括设置在发光单元上的至少一个导光元件，用于接收由发光单元产生的光束，并且导光元件具有形成在该发光单元上的多个微导光结构 其外表面。 因此，本公开不仅能够使发光单元与导光单元配合，以解决使用LED的结果的亮点问题，而且还提供更宽的发光范围。
