Provided is an on-vehicle illumination device which is compact, does not have a space therein, and is capable of realizing a complex curved surface shape. The on-vehicle illumination device includes a light-emitting element disposed on a wiring pattern on a substrate, and an outer lens layer made of a resin and mounted on the light-emitting element. The substrate has a shape curved along a curvature of the outer lens layer in a front-rear direction.

On-vehicle illumination device and production method therefor

The present invention provides a panel capable of switching between a state transparent to external light, a point light emitting state, and a surface light emitting state. Provided is a transparent panel provided with light emitting function, including: an LED die; a light transmitting substrate for LED, on which the LED die is mounted; a wiring pattern provided on a surface of the light transmitting substrate for LED and bonded to the LED die; and a light diffusing panel laminated on the light transmitting substrate for LED. The light diffusing panel includes: a pair of light transmitting substrates for liquid crystal; a liquid crystal layer sandwiched between the pair of light transmitting substrates for liquid crystal; and transparent conductive films disposed on the light transmitting substrates for liquid crystal, and is switchable between a transparent state and a light diffusion state.

Transparent panel provided with light emitting function

Provided is an optically transparent plate having a structure where an LED die is directly mounted on an optically transparent substrate, and light extraction efficiency is improved. The optically transparent plate comprises, an optically transparent substrate, a wiring pattern placed on either of a surface on the upper side and a surface on the underside of the optically transparent substrate, or on both of the surfaces, and the LED die bonded to the wiring pattern. A reflective layer is placed on the other side, of the surface of the optically transparent substrate on which the LED die is mounted. At least a part of the wiring pattern and at least a part of the reflective layer comprise a conductive material obtained by sintering conductive particles.
