Abstract
A timepiece with LED lights 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.
