Inflatable solar powered lamp

摘要

A solar powered lamp is provided with flat ends and a flexible housing, such that the housing can be inflated to form a free standing cylinder. A solar panel faces outward on one of the flat ends for recharging a low-profile rechargeable battery which, under the control of a printed circuit panel, powers an array of LEDs, which point into the lamp housing. Reflective surfaces, facing each other on opposite inside end walls of the lamp, maximize the diffusion of light from the LEDs. The lamp is a durable, portable, long light lighting solution for those who live off the electric power grid, victims of disaster, and the like.

主权项

1. A solar powered lamp, comprising:
a collapsible housing having flat end walls and a side wall; a water-tight seal between the flat end walls and the side wall; a printed circuit board on one end wall comprising a planar array of light emitting diodes (LEDs), wherein the one end wall comprises an inner end wall, an outer end wall and a rigid panel sealed between the inner end wall and the outer end wall; a reflective surface on the inner end wall having apertures positioned over the planar array of LEDs; a rechargeable battery attached to the printed circuit board powering the LEDs; a solar panel on the printed circuit board opposite the array of LEDs adapted to recharge the rechargeable battery; and the circuit board being operatively connected to the rechargeable battery, the LEDs, the solar panel, and a switch for powering the LEDs on and off.
