LIGHT EMITTING DIODE LAMP

摘要

PROBLEM TO BE SOLVED: To provide a light emitting diode lamp which maintains an inner pressure of a glass bulb at the atmospheric pressure.SOLUTION: A light emitting diode lamp includes: a light emitting diode unit 10 on which light emitting diodes 11 are mounted; a glass bulb 21 in which the light emitting diode unit 10 is disposed; and a mouth piece 23 attached to the glass bulb 21. The glass bulb 21 has an opening part 231, which allows atmospheric air to pass, in the mouth piece 23. The light emitting diode lamp includes a narrow tube such as an exhaust tube 221 which allows the interior of the glass bulb 21 and the interior of the mouth piece 23 to communicate with each other and protrudes from the glass bulb 21 into the mouth piece 23. The opening part 231 is formed in a tip part of the narrow tube.
