Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a light source with high control flexibility and low production costs, which is provided for use with white light sources. Electronic devices use the light source structure of light emitting diodes (LEDs) to achieve the lighting requirements required by electronic devices, and they have an increased control capacity and a smaller size than conventional lighting methods. [Previous technology] As generally recognized by the general public, white light sources are widely used light sources for electronic devices. Compared with the traditional RGB three-color light-emitting diodes which emit light separately, they have a smaller volume and have practical advantages. Its development potential can be said to have the practical value of partially replacing the traditional three-color light source, especially in the household scanning seedlings, fax machines, mobile phones, PDAs and LCD screens. The focus of active R & D by several manufacturers. Please refer to the first figure, which is a schematic diagram of the cross-section structure of the conventional white light emitting diode 1 'wherein the light emitting source is a blue light emitting diode wafer 1 2' in practical application 'the aforementioned blue light emitting diode wafer 1 2 series device is contained in the encapsulation material mixed with yellow fluorescent powder 1 4 丨 6, when the blue light emitting diode wafer 12 emits light, part of the blue light can be absorbed by the yellow light emitting powder 14 to emit yellow light, and after passing through the blue light and yellow light The color mixing of light can be used. However, the conventional technology is based on blue; the chip 12 is matched with yellow fluorescent powder 14 as its main feature, but because the raw materials of yellow fluorescent powder 4 are related, the white light emitting diode At present, the cost can not be achieved very low, which is a major shortcoming. Moreover, such an implementer occupies Aα ^, ^, which has a narrow range of color temperature control, which has limited application effects.
