A plurality of areas 221 are formed by being surrounded by a plurality of straight lines 222, and a film is attached to each of the areas 221 to form a color area. In other embodiments, the cover 22 forms a plurality of color areas 221 by combining from a plurality of color glasses in a regular or irregular shape. In use, the white light emitted from the light emitting diode lamp 104 after being driven by the driving device 25 passes through the color area 221 of the cover 22 and then changes into colorful multicolor light.

  In other embodiments, the light emitting diodes 244 arranged to face the cover 22 are distributed in groups of specific regular or irregular shapes. Each group is a color light emitting diode of a specific color. When the light emitting diode of each group is energized, the light of the specific color emitted from the light emitting diode is transmitted through the transparent cover 22 and then the crystal clear light. It is visually recognized as a light emitting diode. In other embodiments, the light emitting diodes 244 arranged to face the cover 22 are distributed in groups of specific regular or irregular shapes.

As a result, a plurality of color spots are formed on the light emitting surface of the light emitting diode lamp 104. Here, the light emitting diode 244 is a color light emitting diode. Each group of light emitting diodes comprises at least one light emitting diode 244. Accordingly, it is not necessary to design a complicated drive circuit in the light emitting diode lamp 104, and a colorful effect can be produced by changing the arrangement of the light emitting diodes 244 or the cover 22 of the light emitting diode lamp 104.

There is no need to change. Further, even if the connection portion is damaged, it is not necessary to change the light emitting diode lamp by simply changing the connection portion, thereby reducing unnecessary expenses. Since the transparent cover is adopted, a crystal clear light emitting diode appears and produces a colorful effect.
