Title:
LIGHTING FITTING AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2001291901
Kind Code:
A
Abstract:

To provide a lighting fitting where utility efficiency of illumination light and electric power is superior and reduction of manufacturing cost is enabled by simplifying a structure, including the lenses.

In this lighting fitting, a plurality of LEDs are arranged facing a prescribed direction and being capable of lighting, at least light emitting parts of the LEDs are buried in lenses, and directivity of the LEDs is controlled by the lenses. By using the LEDs as light sources and burying the light emitting parts of the LEDs in the lenses, utility efficiency of illumination light and electric power can be improved, heating value and temperature rise can be restrained when the LEDs are lit, and a structure of the lighting fitting, including illumination light lenses can be simplified.
