Abstract
An LED lamp including a circuit substrate (22) on which an electrode pattern is formed, a reflecting frame (31) including a tapered concave portion (32) having an inner peripheral surface broadening toward an upper end of the reflecting frame, a light emitting unit (27) disposed on a central portion of the concave portion (32), an air layer (40) disposed above the light emitting unit (27), and a lens body (44) provided through the air layer above the reflecting frame (31), the reflecting frame being provided with an air hole (45) for communicating the air layer with an outside area of the LED lamp.

An LED lamp comprising:
- a circuit substrate provided with an electrode pattern;
- a light emitting unit mounted on said circuit substrate;
- and
- a reflecting frame mounted on said circuit substrate and including a concave portion disposed to surround said light emitting unit,
- a reflecting surface for reflecting light emitted from the light emitting unit being formed on an inner peripheral surface of the concave portion,
- said reflecting surface having a taper shape configured to broaden toward an upper end of the reflecting frame.
An LED lamp comprising:
- a circuit substrate provided with an electrode pattern;
- a light emitting unit mounted on said circuit substrate;
- a reflecting frame mounted on said circuit substrate and including a concave portion disposed to surround said light emitting unit;
- a lens body disposed above the light emitting unit and attached to said reflecting frame to form an air layer between the light emitting unit and the lens body;
- and
- an air hole provided in at least one of the circuit substrate, reflecting frame and the lens body for communicating the air layer with an outside of the lamp,
- a reflecting surface for reflecting light emitted from the light emitting unit being formed on an inner peripheral surface of the concave portion,
- said reflecting surface including a taper shape configured to broaden toward an upper end of the reflecting frame.
