Film for led lighting equipment, and led lighting equipment

Abstract

Provided are: a film for an LED lighting apparatus, which allows the front surface and/or back surface of a light guide unit to have any appropriate film laminated thereon, or to be subjected to any appropriate surface treatment, while suppressing a reduction in waveguide efficiency of light in a lighting apparatus having an LED light source arranged on one end surface of a light guide plate and being configured to emit light from an end surface opposed to the end surface (entrance end surface) on which the LED light source is arranged; and an LED lighting apparatus including the film for an LED lighting apparatus. The film for an LED lighting apparatus of the present invention includes: a base material; and a low-refractive index layer arranged on at least one side of the base material. In one embodiment, the low-refractive index layer has a refractive index of 1.25 or less.
