Claims24
A light-emitting module comprising:
- a light-emitting panel comprising:
- a transparent film having a flexural modulus of approximately 0 to 320 kgf/mm2 (excluding zero),
- a conductor layer provided on one surface of the transparent film,
- a plurality of light emitting elements having an electrode connected to the conductor layer, and
- a resin layer that holds the plurality of light emitting elements on the transparent film and has a tensile storage modulus EM of 0.01 to 1000 GPa in a range of 0° C. to 100° C.;
- and
- a board having flexibility higher than that of the light-emitting panel and comprising:
- a substrate with insulation,
- a plurality of first conductor patterns provided on one surface of the substrate and connected to the conductor layer of the light-emitting panel,
- a plurality of second conductor patterns provided on the other surface of the substrate, extending so as to intersect the plurality of first conductor patterns, and connected to the conductor layer of the light-emitting panel, and
- a plurality of vias for conducting the plurality of first conductor patterns and the plurality of second conductor patterns,
- wherein the plurality of light emitting elements selectively emit light when a voltage is selectively applied to the plurality of first conductor patterns and the plurality of second conductor patterns.
A light-emitting module comprising:
- a transparent insulating film having a total light transmittance of about 5 to 95% and a flexural modulus of about 0 to 320 kgf/mm2 (excluding zero);
- a conductor layer provided on one surface of the transparent film;
- a plurality of light emitting elements having a pair of electrodes;
- a resin layer having, a tensile storage elastic modulus EM in the range of 0° C. to 100° C. of 0.01 to 1000 GPa and holding the plurality of light emitting elements on the transparent film;
- a first conductor pattern provided on the transparent insulating film and connecting one electrode of the plurality of light emitting elements in parallel;
- a second conductor pattern provided on the transparent insulating film and connecting the other electrodes of the plurality of light emitting elements in parallel,
- wherein:
- when a voltage is applied to a predetermined position of the first conductor pattern and the second conductor pattern to cause the light emitting elements connected in parallel to emit light, the difference ΔI(=Imax−Imin) between the first current value of the current flowing through the light emitting element at an end portion and the second current value of the current flowing through the light emitting element at a center portion is 5% or less of the first current value, and
- when the light emitting device is observed at a distance of about 40 cm or about 3 m, there is almost no difference in light emission intensity between the plurality of light emitting elements.
