Abstract

The area illumination for a LED night light to apply a simple very roughly surface light-medium has the input-end to receive the said LED light beams to travel within the said light-medium and majority of the light beams can be seen on the all surface of the said light-medium. The spot LED light source with narrow viewing angel to change to the certain surface'"'"'s area illumination by apply the current invention very roughly surface light-medium with optionally add the frosted sheet on the visible surface of said light medium incorporate with the sealed-unit safety concept will be the big improvement for the safety and light illumination appearance to people.

Claims

1. The Area illumination for a LED night light consist of;

At least one of the light-medium has very rough surface to allow LED light beams to travel within and majority of light beams can be seen on the said light-medium surface by viewer.

At least one of the housing which has at least of one prong means to connect with the power source and one location of the said housing with area illumination.

At least one of LED connect with related circuit, control means, and prong means disposed within the said housing to make the said LED to be turn on under predetermined functions and period of time.

The improvement including;

The said light-medium very rough surface to make the LED light means point light beams to be spread out to whole surface of the said light-medium to be seen by viewer.

A frosted front sheet optionally adds on the location adjacent to the light-medium visible surface to make perfect photometric and cosmetic appearance of the visible surface.

2. The Area illumination for a LED night light consist of;

At least one of the light-medium has very rough surface to allow LED light beams to travel within and majority of light beams can be seen on the said light-medium surface by viewer.

At least one of the housing which has a sealed-unit and its prong means to connect with power source and one location of the said housing with area illumination.

At least one of LED connect with related circuit, control means, and prong means sealed within the sealed-unit case to make the said LED to be turn on under predetermined functions and period of time.

The improvement including;

The said light-medium very rough surface to make the LED light means point light beams to be spread out to whole surface of the said light-medium to be seen by viewer.

A frosted front sheet optionally adds on the location adjacent to the light-medium visible surface to make perfect photometric and cosmetic appearance of the visible surface.

3. A sealed-unit for LED light device consist of:

At least one of housing to allow the prong means, LED related circuit, control means sealed into a safety standard plastic material which meet the safety standard'"'"'s certain flammable grade under some supplier and wall thickness.

At least one of the LED(s) to connect with the said LED related circuit and prong means to get the power and functions under predetermined features for illumination. The said LED may dispose of the said sealed-unit, connected by conductive wire, or install on the surface of sealed-unit without see the electric metal legs.

The said prong means can be fix on the location or swivel type.

The sealed-unit can be assembly with the said light device by conventional available skill of the art to make a final product.
