Solar cell charger with lens for portable applications
View Patent ↗A portable electronic device includes a housing including an outer surface and an inner surface. A core electronic component is configured to be provided inside of the housing. A transparent material is provided at the outer surface of the housing. A solar cell is provided on the inner surface of the housing and spaced apart from the transparent material by a predetermined distance. The transparent material is configured to receive light from an external source and direct the light to the solar cell.
1. A portable solar-powered charger comprising a housing and a removable rectangular electronic component configured to be received by the housing, wherein the housing includes:
a lens provided on a top outer surface of the housing;
a divider provided inside the housing to divide the housing into a solar cell compartment and a main compartment directly below the solar cell compartment, wherein the solar cell compartment has a solar cell separated by a predetermined distance below the lens to receive the concentrated light from the lens, and wherein the main compartment has an opening to receive the removable rectangular electronic component inside the main compartment; and
a battery module provided within the solar cell compartment to be charged by the solar cell;
wherein the removable rectangular electronic component includes an internal battery inside the removable rectangular electronic component and is configured to be docked into or undocked from the main compartment such that when the removable electronic component is docked into the main compartment the internal battery couples to the battery module to receive energy from the battery module; and
wherein the removable rectangular electronic component is selected from the group consisting of a phone, a personal digital assistant, and a calculator.
2. The portable solar-powered charger of claim 1 , wherein the divider has an upper surface and a lower surface, wherein the solar cell and the battery module are disposed above the upper surface of the divider, and wherein the removable rectangular electronic component is disposed below the lower surface of the divider after the removable rectangular electronic component is received onto the main compartment.
3. The portable solar-powered charger electronic device container of claim 1 , wherein the lens is a Fresnel type lens produced from a transparent polymer material.
4. The portable solar-powered charger of claim 1 , wherein the lens has a lateral dimension Z, wherein the solar cell has a lateral dimension W, and wherein a ratio of Z to W is a value selected from the group consisting of: 1.2, 1.3, 1.5, 1.7, 1.9, 2.0, 2.5, and 3.0.
5. The portable solar-powered charger of claim 1 , wherein the housing further comprises a second lens formed on the top outer surface of the housing and a second solar cell disposed below the second lens, wherein the second solar cell is contained within the solar cell compartment to receive concentrated light from the second lens to charge the battery module.
