摘要：
A lamp comprises: a primary reflective mirror being funnel-shaped and having an opening at one end; LEDs disposed within the primary reflective mirror; a base attached to another end of the primary reflective mirror; and a circuit configured to receive power via the base and cause the LEDs to emit light. The circuit unit is housed in a circuit case and disposed within the primary reflective mirror close to the opening in a direction in which the LEDs emit light. The circuit case has a secondary reflective surface configured to reflect light emitted from the LEDs to a reflective surface of the primary reflective mirror.
