Abstract
A night light includes a housing, AC-to-DC circuitry, at least two prongs configured to connect to a power source outlet, at least one LED, first and second optical elements for converting light beams from the LED into substantially uniform light emitted from the optical elements, a switch configured to manually select from a plurality of illumination modes, sensors to automatically select between the illumination modes, and means for wireless communication, and at least one second optical element. The LED might be a multi-color LED.
Claims18
An LED night light, comprising:
- a lower prong base including prongs configured to be plugged into a power outlet;
- at least one LED and an AC-to-DC circuit provided in the lower prong base;
- at least one first optical element having a shape selected from the group consisting of a flat, cone, tube, and dome shape, said first optical element at least partially assembled with the prong base and arranged to receive incident light from the at least one LED;
- a second optical element coupled to the prong base, and having at least one of a textured finish, a whitening treatment, light passable areas, painting, printing, or an opening,
- wherein the LED night light is configured to provide multiple reflections and refractions within the surfaces of the LED night light and a wall to which the LED night light has been attached.
2 more elements
An LED night light, comprising;
- a sealed prong unit having
- (1) at least one built-in prong,
- (2) at least one LED,
- (3) at least one of circuitry, a trigger-system, a sensor, and a switch, and
- (4) an AC-to-DC circuit,
- with or without an integrated circuit to cause the LED night light to exhibit at least one of a single, multiple, or variable light color, brightness, function, or effect,
- a first optical element in front or on a side of the at least one LED to receive LED light beams and eliminate LED bright spots, and create substantially uniform light beams, and
- at least one second optical element that having an opening on at least one of a rear, top, and side, and that is assembled to the sealed prong unit,
- wherein the substantially uniform light beams are shown on a front surface of the second optical element and wherein the LED light beams are also emitted to a home wall having an AC outlet for plugging the night light into.
6 more elements
A LED night light, comprising;
- at least one dice or chip LED mounted on a printed circuit board;
- at least one prong unit having an isolated individual space containing only the at least one LED and printed circuit board so that light beam traveling within the space does not encounter other electric parts within the space;
- at least one first optical element fitted within the prong unit and positioned in front or on a side of the at least one LED, which is at least one of a single color LED and multiple different color dice or chips built-in a single LED;
- and
- at least one second optics-piece having at least one of a cartoon mask and a cartoon character piece having an opening or light transmitting window treatment, and
- wherein the night light is configured to provide multiple reflections and refractions within the isolated individual space inside the prong unit to eliminate super bright LED lighted spots, the light beams exiting from the isolated individual space being emitted to the second optical element which has an opening on at least one of a rear, top, or side to enable the light beams to be projected onto a wall to which the LED light has been attached,
- wherein at least a portion of the uniform light is emitted to a wall having an AC outlet for plugging the LED night light into.
