Abstract
A light-emitting device of a very simple configuration in which uniform LED light illumination can be obtained with a low light quantity loss, the device having a low production cost, improved emission characteristic and excellent cost efficiency and reliability. A transparent body is disposed in the vicinity of a LED, and a light-scattering layer that scatters the light of the LED is formed by coating on the light-illuminating surface of the transparent body through which the light of the LED passes. The light-scattering layer contains 2.5 parts by weight to 4 parts by weight of a filler and has a thickness of 5 μm to 20 μm.
Claims7
A light-emitting device that has a LED as a light source, comprising:
- a transparent body that is disposed in the vicinity of the LED or so as to incorporate the LED inside thereof;
- and
- a light-scattering layer that scatters light of the LED, which is formed by coating, within the surface of the transparent body, on a light-illuminating surface that illuminates the light from the LED to the outside.
