Illumination indicator for doorbell

A lighting indicator (5) for a doorbell (1) may be arranged to receive light along an optical axis (e.g., perpendicular to a front face of a doorbell housing), and to emit light from an output portion defining a closed loop (e.g., extending around the optical axis) and in a direction parallel to the optical axis. The lighting indicator (5) may include a light tube (51) that receives light along an optical axis and reflects the light to follow a radially outward and diverging path, such as a radially outward and diverging path perpendicular to the optical axis. Radial outward and diverging light may be reflected to follow a path parallel to the optical axis for emission at the output portion of the light pipe. The light pipe may be configured to transmit a doorbell switch actuation force to other portions of the doorbell to cause actuation of the switch. 一种用于门铃(1)的照明指示器(5)，该照明指示器可以布置成沿着(例如，与门铃壳体的前面垂直的)光轴接纳光，并且将光从限定(例如，围绕光轴延伸的)闭环的输出部分且沿平行于光轴的方向发射。照明指示器(5)可以包括光管(51)，该光管沿着光轴接纳光并且将光反射成遵循径向向外且发散的路径、例如垂直于光轴的径向向外且发散的
