Embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

The control device of the utility model light-emitting diode as shown in Figure 4, includes at least:

One substrate 10, its substrate 10 is provided with plural loop 11, and each loop 11 also is connected with LED chip 20 respectively.

A plurality of LED chip 20, be laid on the substrate 10, each LED chip 20 comprises a luminescence chip or a plurality of luminescence chip, please consult simultaneously shown in the embodiment of Fig. 5, this LED chip can include a red light-emitting chip 21, a green luminescence chip 22 and a blue light emitting chip 23, is connected with this loop 11.

One transparent body 30, substrate 10 and a plurality of LED chip 20 are packaged in the transparent body 30, to form a light-emitting diode, its transparent body is soft or pliability, so can give this light-emitting diode and form a rope form light-emitting diode structure, and can put along with the profile for the treatment of ornament, to highlight the profile for the treatment of ornament.
