The present invention relates to a white multi-wavelength light emitting diode, in particular capable of producing an accurate light color, effectively improving the effect of expressing the brightness of the light emitting diode structure and the related manufacturing method.

The basic structure of a general light emitting diode covers a light emitting element with an associated sealing material (colloid), and it is comprised by connecting a light emitting element electrode and an associated electric circuit using a metal wire. Under the action of electricity in the light emitting element, a light source is produced by the light emitting element, the light source is projected to the outside via the sealing material covering, and the light source of the light emitting element and the fluorescent material wavelength in the center of the sealing material are combined, A light color is formed.

  As shown in FIG. 1, a white light emitting diode structure which is commonly produced and used in the related art, the light emitting diode of this type has a sealing material 30 after fixing the blue light emitting element 21 to the cup-shaped carrier 10. ) It is a structure that accommodates a structure. Further, a solid crystal binder 40 (solid crystal adhesive) is provided between the indigo blue light emitting element 21 and the carrier 10 (or similar substrate) to fix the indigo blue light emitting element 21. In addition, in the general embodiment, the conventional white light emitting diode has a wavelength of the red phosphor 52 and the green phosphor 53 in the light source and the sealing material 30 of the blue light emitting element 21 as shown in the figure. Combined, white light is produced. Another white light emitting diode structure, which is also produced and used conventionally, uses a fixed crystal binder to fix the indigo element in the center of the carrier, and also connects the indigo element and the electrode end by using a metal wire, and the fluorescent material The fluorescent binder is provided to cover the indigo element, and under the energization action in the indigo element, the light source of the indigo element is excited to form a predetermined light color through the fluorescent material made of the fluorescent bonding material.

For this reason, the white light produced by the white light emitting diode is necessarily configured by combining the wavelength of the phosphor (or fluorescent) of a color corresponding to the light emitting device of a specific color.
