It is AA arrow sectional drawing which shows the structure of a mounting type LED package.

  In the present embodiment, as shown in FIGS. 1 and 1 -A, the LED package is a surface mount type LED package 1. The surface-mounted LED package 1 is a ceramic 12 or resin molded capacities 12, purple LED elements 10 mounted on the capacities 12, and purple light energy emitted from the purple LED elements 10 formed on the inner surface of the capacities 12.

In this embodiment, purple LED elements and RGB phosphors are used. However, as shown in FIG. 1B, white light energy may be emitted by a combination of blue LED elements 11 and yellow phosphors 17. . In that case, since the combination of the blue LED element 11 and the yellow phosphor-containing sealing material 17 emits almost no ultraviolet rays, the countermeasure against ultraviolet rays is not so necessary. Also, the anode electrode and cathode electrode on the package, and the metal wires that connect them to the purple LED element 10 are not shown.

  1A is a violet LED element 10, and the violet light energy 74 emitted from the violet LED element 10 is applied to the R, G, B phosphors contained in the sealing material 15 to emit light.

The purple LED module 20 in which a plurality of surface-mounting purple LED packages 1 used in the present embodiment are connected to each other emits ultraviolet light 69 (ultraviolet light energy 73) together with white light energy 68 by simultaneous additive color mixing. The organic thin-film transparent solar cell 100 that generates a high electromotive force by adjusting the amount of ultraviolet light by adjusting the increase or decrease of the RGB phosphors absorbs the ultraviolet light energy 73 emitted and emitted from the purple LED module 20, and the photovoltaic power The electromotive force generated in-house by the effect is supplied to the purple LED module 20 via the DC controller 111 (not shown) or stored in the secondary lithium ion storage battery 120 (not shown). The generated voltage of the electromotive force generated by the organic thin-film transparent solar cell 100 depends on the amount of incident light of the ultraviolet light energy 73, so that the voltage as it is cannot be used. Therefore, a DC controller 111 that controls the generated voltage generated by the organic thin-film transparent solar cell 100 so as to be compatible with a supply destination such as a purple LED module 20 or a secondary lithium ion storage battery 120 is provided. After the generated voltage from the organic thin-film transparent solar cell 100 is controlled by the DC controller 111, the purple LED module 20 or the secondary lithium ion storage battery 120 is charged.

The electromotive force generated by absorbing the ultraviolet light energy 73 and generated by the photovoltaic effect is stored in a lithium ion storage battery 120 (not shown). The transparent UV cut film 104 absorbs and extinguishes the remaining ultraviolet light 69 that has not been absorbed by the organic thin film transparent solar cell 100 after it is absorbed by the organic thin film transparent solar cell 100 and generates an electromotive force, and does not contain the ultraviolet light 69. The light energy 68 is transmitted as it is to prevent the adverse effect of radiating the ultraviolet rays 69 to the liquid crystal panel 50 and the human body existing from the UV cut film 104. The liquid crystal panel 50 includes a polarizing plate 60, an array substrate 61, a transparent electrode (subpixel electrode) 62, a light distribution film 63, a liquid crystal layer 64, an upper light distribution film 65, a transparent electrode (common electrode) 66, and an upper polarizing plate 67. And are laminated in this order. The ultraviolet light energy 73 emitted and emitted from the light source is absorbed by the organic thin film transparent solar cell 100 to generate electromotive force, and the remaining ultraviolet light 69 that cannot be absorbed by the organic thin film transparent solar cell 100 is a transparent UV cut film. Light energy 68 that has been absorbed and extinguished by 104 and does not contain ultraviolet light 69 is supplied to the liquid crystal panel 50, and the liquid crystal panel 50 is turned on. The light energy 68 that illuminates the liquid crystal panel 50 becomes visible light and eventually disappears.

(Configuration of transparent UV cut film)
Further, as shown in FIG. 2, the transparent UV cut film 104 is formed immediately outside the organic thin film transparent solar cell 100 as viewed from the LED module 20 and is absorbed by the organic thin film transparent solar cell 100 to generate an electromotive force. By absorbing and extinguishing the ultraviolet rays 69 that could not be absorbed by the organic thin-film transparent solar cell 100, and transmitting the light energy 68 that does not contain the ultraviolet rays 69 as it is, the liquid crystal panel 50 existing from the transparent UV cut film 104 or the like Prevents adverse effects of radiating ultraviolet rays 69 to the human body. In this embodiment, the transparent UV cut film 104 is used, but other materials may be used as long as they are transparent and absorb and extinguish the ultraviolet rays 69. In addition, if the organic thin film transparent solar cell 100 absorbs ultraviolet rays to some extent and the liquid crystal panel 50 existing outside the organic thin film transparent solar cell 100 or the human body is less affected by ultraviolet rays, the transparent UV cut film 104 is not formed. Also good.
