- a third substrate for example, a glass substrate 21 was used as the protective portion 3, and an Ag film 29 having a high reflectance was formed on the surface of the glass substrate 21 by RF sputtering.
- the light emitted from the light emitting unit 2 can be emitted to the power generation unit side without leaking to the side opposite to the power generation unit that is the solar cell unit 1.
- the reflectance on the glass substrate 21 This is not the case if it is a force metal film using a high Ag film 29.
- A1 foil or metal foil such as Ag foil may be bonded with an adhesive.
- the glass substrate 21 may not be translucent. It can be colored glass, metal plates such as Al, stainless steel, gold, silver, copper, or wood or plastic.
- the first light emitting layer is a light emitting layer between the solar cell unit 1 and the light emitting unit 2.
- the EVA (ethylene butyl acetate) layer 16 that is thicker than the height of the chip LE D19 placed in part 2 is sandwiched.
- an EVA layer 20 as a second adhesive layer is sandwiched between the light emitting unit 2 and, for example, a glass substrate 21 as a third substrate for protecting the light emitting unit 2. Then, hold at 130 ° C for 20 minutes to melt the EVA, and then hold at 150 ° C for 45 minutes to crosslink the EVA.
- force using the glass substrate 21 to protect the chip LED 19 may be replaced with fluorine resin having a high resistance.
- a plastic substrate with no heat resistance such as polycarbonate for the first translucent insulating substrate, the second translucent insulating substrate or the third substrate, it is necessary to use a low temperature EVA. .
- the EVA after holding the EVA at 120 ° C for 10 minutes to dissolve the EVA, the EVA may be crosslinked by holding at 130 ° C for 45 minutes.
- the solar cell portion 1 that generates power during the daytime and the light emitting portion 2 that emits light when power is supplied are physically integrated so that the power generation region and the light emission region overlap.
- the LED light emitting module is oriented in the direction of the power generation unit, the light emitting unit area and the power generation unit area can be secured at the installation location without any restrictions on the installation area. Can be installed. Further, it can be used in combination with a solar battery or other batteries, for example, for outdoor lighting or a guide sign.
- FIG. 8 shows a light emitting module having the same configuration as that of the fourth embodiment except that the main light emitting direction of the LED 19 is opposed to the reflecting portion with respect to the light emitting module of the fourth embodiment shown in FIG. Is shown.
- the solar cell unit 1 that generates power during the daytime and the light emitting unit 2 that emits light when supplied with power are physically integrated, and is opposite to the power generating unit 1.
- the main light emitting direction of the chip LED 19 is oriented in the direction of, and the second light-transmitting insulating substrate 17 is interposed between the power generating unit 1 and the light emitting unit 2 so that the electrode 12 of the power generating unit 1 is disposed. And the circuit pattern 18 of the light emitting section 2 are better insulated.
- the light-emitting module manufactured as described above is also not limited by the installation area because the light-emitting area and the power-generating area are secured at the installation location, as in the first embodiment. It becomes possible to install it. In addition, it can be used in combination with solar cells and other batteries, for example, for outdoor lighting and information signs.
- an example of an installation location of the force light-emitting module in which some embodiments have been described is laying on a wall surface of a building or the like.
- the light emitting module and the light emitting system of the present invention can be widely applied to small-sized or large-sized lighting, guide labels, and the like.
