  • BACKGROUND
  • The current invention to use the most simple light-medium with very roughly surface to make the sport light means such as LED to become the wide spread out light beams for a certain surface with area illumination. To make the narrow viewing angel of the spot light beams to become a surface with area illumination already adapted for decades especially for the cellar phone, computer, PDA screen. However, all these technical apply the very expensive optics member which is clear plastic lens and one side of the surface with a lot of the raised points and these points mainly are reflect the incoming light beams to variety directions. The plurality of the raised spots arranged on the one side of the clear lens to make a plurality of false tiny light spots inside the lens. Further apply the reflective material on the 4 other sides to block out the light been leakage from these 4 sides. The front visible surface need to add a milky optics member to make the plurality of false light spots become diffusion to make the even surface light for area illumination. These prior art only get the area illumination on one of the 6 surface not like the current invention is all surface of the light-medium with visible area light so it will be more wide application by the current invention.
  • For example the U.S. prior art U.S. Pat. No. 6,987,710 same inventor as U.S. Pat. No. 7,054,233 both prior art teach the illumination module back surface has the reflective properties to allow the light beam reflect in the interior of the module and out from the front surface (Abstract line 7 to line 9, and the details description stating The back side of reflectors 38, 48 or 78 could alternatively be engraved to provide multiple raised surfaces, such as points, bumps, protuberances, or the like. FIGS. 14 and 15 illustrate surfaces 86 and 87, respectively, created by dot engraving techniques). The said illumination module is very expensive to make this compare with current invention. The current invention light-medium which just have the very rough surface surround the medium and make all the light beams travel within the said light-medium. This rough-surface treatment has more diffusion effects than the said prior arts reflective optics property. Further more, the prior art want to control the light beams only “out of the front surface” this is mission impossible and can not control at all. The current invention do allow the light emit out to all directions to all surface though the rough-surface of the light-medium to viewer. Some directions light beams will be block out by the housing so can get desired light effect as wish. The both Kibiloski prior art did not teach a frosted front sheet to make the illumination module to get the best photometric and make the cosmetic appearance for the visible surface so it is impossible to make a commercial items without this frosted front sheet on top of the illumination module.
  • The LED are positioned with light-medium's input-end to make majority of light beams travel within the said light-medium and to be seen the brightness on light-medium's surface basing the very roughly surface of the light-medium to block out all the light beams to be emit out of said the surface of the light-medium. This is not same as other optics design which have shinny surface and with a lot of raised spots on lower surface to make the single LED light spot become a plurality of tiny light spots with front frosted-lens to make it become even photometric. The other optics design from conventional market adapted very expensive shinny surface optics parts, the current invention use a roughly light-medium can get better and more even photometric under much low cost for this light-medium. This is big improvement than the other optics design.
  • The other features of the current invention to disclosure the LED circuit within a sealed-unit for very important to improve the LED night light safety.
  • The sealed-unit case material is preferable to use the plastic with certain thickness to pass the 94-V-0 flammable grade to meet the safety standard and all other housing part without any limitation because without touching the live wires.
  • The base can be any shape, configuration, design, curvature, thickness, material, dimension with build-in or separated receptacle means. The sealed-unit has LED related circuit, control means, prong means disposed within, this can design for super slim and wider unit or thicker for small unit which depend on the market requirement. For convenience, It also can make a desired unit which can fit into different base shape such as Rectangular shape for area illumination for LED night light application is the best design.
  • DRAWING
  • FIG. 1: Disclosure the 1st embodiment for area illumination for LED night light for detail construction to apply the light-medium to let LED light beams to travel within the said light-medium and can see the very evenly light brightness from light-medium surface.
  • FIG. S: Disclosure the preferable 2nd embodiment for said sealed-unit which seal all the LED related circuit, prong means, control means within the very safety case to prevent from people t touch the any electric components which have any connection with live wires which have high voltage at certain frequency. It also disclosure the sealed-unit with LEDs construction to fix on the light device with details description so this is universal model can fit to all kind of night light device.
  • DETAIL DESCRIPTION
