Patent ID: 6851209

Claim:
An integrated advertisement board, comprising: a frame; a plurality of light emitting elements arranged on the frame in a form of a matrix; a controlling circuit electrically connected to the light emitting elements for making each light emitting element emit light and stop emitting light in an alternate way for the light emitting elements to present patterns with constantly changing appearance; the controlling circuit being capable of being set up such that different lines of light emitting elements take turns emitting light while a pattern is presented; and being characterized by the light emitting elements, each of which consists of: a base having a holding room on a rear side thereof, and a cover for covering the holding room thereof; the base having a transparent inner shell projecting from a front side thereof and in communication with the holding room; the inner shell having a rear connecting portion; an LED; the LED being joined to a first circuit board of the controlling circuit by means of welding; the first circuit board being disposed in the holding room with the LED being disposed in the inner shell; and a transparent spherical shell having an opening; the spherical shell being passed over the inner shell at the opening and joined to the rear portion of the inner shell for cooperating with the outer shell to concentrate light emitted from the LED twice.
