Abstract

An LED light with a time piece uses a simple light-medium body with a very rough finish to allow light from LED(s) to pass though input-end(s) of the light-medium body and travel within the body and obtain a very even brightness on all surfaces of the light medium that are seen by a viewer. Combined with a milky/frosted front sheet overlay, the light-medium surface can get perfect area illumination effects. The movement for the time display can include analog indicators with a guilt-in light-medium on the top cover to achieve a super slim LED illumination for the time piece. For night light application, the sealed-unit may consist of prong-means and an LED related circuit sealed within a safety standard plastic material and assembled with the night light body to save a lot of cost enable use of all kinds of materials. The invention may also be adapted to an LCD display timepiece.

Claims

1. An LED light means with an analog time piece, comprising:

at least one time piece arranged to offer a time related message though a display unit, the display unit including at least an hour hand and a minute hand;

at least one cover extending to the side of and in front of said hands to protect said hands of the display unit;

at least one LED light means disposed within said cover;

at least one time piece movement included in said display unit; and

at least one prong means for supplying power to the LED light means and an LED drive circuit and control means for controlling an illumination function of the LED light means,

wherein a first portion of the cover that extends around but is not in front of the hands is arranged to serve as a light guide for causing light beams emitted by the at least one LED light means to travel through the first portion of the cover and be emitted through a surface of said first portion of the cover that extends around but is not in front of said hands, and

wherein a second portion of the cover that is in front of the hands is clear to allow a viewer to view the hands.

2. An LED light means as claimed in claim 1, wherein said first portion of the cover has a textured or milky/frosted surface treatment.
