Glow-in-the-dark lamp shade

机译:夜光灯罩

摘要

A lamp shade or similar article includes a glow-in-the-dark region with a first side disposed toward a light source so that the light source illuminates the first side and with a second side disposed away from the light source. The glow-in-the-dark region includes a glow-in-the- dark substance that stores energy from illumination and that responds to the stored energy by emitting light in the visible range. A portion of the light emitted by the glow-in-the-dark substance exits from the second side. If the first side is illuminated with sufficient intensity, the light exiting from the second side after illumination ceases is sufficient to be perceptible by a human in ambient darkness. The glow-in- the-dark substance can be a glow-in-the-dark ink applied to a cloth layer that is bonded to a transparent plastic layer of the lamp shade. The glow- in-the-dark ink can form a pattern that is bounded by an edge, and the surrounding background can include another colorant. If the background colorant has a darker absorption color than the glow-in-the-dark ink, the pattern will be visible as a light pattern on a dark background both during illumination and after illumination ceases. If the background colorant has approximately the same absorption color as the glow-in-the- dark ink, the pattern will not be visible during illumination, but will emerge as a light pattern on a dark background after illumination ceases.
