Description of the new type: [Technical field to which the new type belongs] This creation is-a kind of light-emitting diode element 'especially-a kind of light-emitting diode element with two different color sources' special collection-a type with a white light source Two-color light-emitting diode. [Previous technology] > Domain has been in the human life 'for a long time-has always played a pivotal role'. 'With the continuous advancement of science and technology' has developed light emitting diodes (Light Emitting Diode; LED) in the 1970s, As compared with traditional light sources, LEDs have smaller volume, longer life, less breakage, lower power consumption, no heat radiation and pollution by toxic substances (such as mercury), so they have always attracted the attention of the market. Nowadays, with the gradual maturation of the technology for producing light-emitting diodes (LEDs), many different light-emitting diodes (LEDs) of different systems and colors have been developed. These light-emitting diodes (LEDs) are used in various fields, and Occupy a pivotal position in the display market (such as consumer electronics), especially after the white light diode technology matures, the current light emitting diode (LED) is currently working hard to advance to the lighting market. In order to meet the diversified needs of market consumers, some light-emitting diodes (LEDs) can already be made into light-emitting diodes (LEDs) of various light color sources. Currently, two-color light-emitting diodes with white light sources are generally available on the market. At least all of the following structures are included, please refer to "Figure 1" for a schematic diagram of the structure of a conventional two-color light emitting diode with a white light source. The conventional two-color light-emitting diode 1 includes at least three diode pins 5 M278068 20 'both of which are provided with a bearing portion 2b to carry the first chip gamma and the second chip i0b, where the first -The wafer 10a is attached to the bearing part with a general colloid u, and then the electrode layer of the first wafer 10a and the conductive end of the diode pin 20 are connected with the metal wire 30, and finally the metal and wire 3. After the wire bonding is completed, the first wafer 10a needs to use the fluorescent layer 40 as the first-stage packaging. The purpose is to package the first wafer technology and the glory material on the carrier 21, and The corresponding positions of the first wafer 10a and the glorious material are fixed. • The first wafer 10b is also attached to the carrier knife with a general colloid u, and then the electrode layer of the second wafer 10a and the conductive end of the diode pin 20 are connected by a metal wire 30, and finally the metal After the wire 3G bonding wire BQn is completed, the tree H is used as the first # and then packaged. When the first chip 10a receives the working voltage, the blue light emitted by the chip will pass through the fluorescent layer 40 first. The complementary color of the fluorescent substance is excited to achieve the purpose of generating a white light source ', and when the second chip is surveyed to receive the operating voltage, it will generate light sources of other colors. [New content] The aforementioned bi-color light emitting diode of the conventional white light source can use the changes in the work to make the first wafer 1 () a produce a white light source, or make the second wafer produce another light source with another color. Please refer to "Figure 2" for a schematic circuit diagram of a conventional two-color light-emitting diode with a white light source. However, since the first chip needs to be completely encapsulated in the camping light layer, the supporting part provided with the first chip cannot accommodate both Set the second chip, so that the number of pins of the two-color light-emitting diode of the white light source must be used on 3 pieces of 6 M278068. In view of this, this creation proposes a two-color light-emitting diode with a white light source 'the purpose of which is to reduce the number of pins of the conventional white & light-source two-color light-emitting diode' and further simplify the two-color light source with a white light source How to use the light-emitting diode 'This two-color light-emitting diode; the body element system includes-a self-colored light source and another-colored light source' and said two crystals; and the resin is encapsulated in the body, this two-color light-emitting After the diode component is packaged, only two external connection terminals are needed, and the two external connection terminals are connected to X in different directions to serve as electrical power, so that the two-color light-emitting diodes can emit light sources of different colors. Regarding the details and technology of this creation, I will explain it with the drawings as follows: [Embodiment] This creation is a kind of two-color light-emitting diode with a white light source. First of all, I will make this two-color light-emitting diode structure—details, please Refer to "Figure 3" for the schematic diagram of the structure of the two-color light-emitting diode with white light source. The two-color light-emitting diode of this creation, ah, contains a white light source and another light source of its color. 'This diode contains two sets of crystals—the wafer receives the fish t wafer 10b), and generally wins. Body 1 fluorescein glue u and two diode pins 0 and so on. ^, Where the first wafer 1Ga is a blue light source crystal that can emit a blue light source, and the second wafer is a light source wafer that can emit other colors. A diode pin 20 in 1 is provided with Carrying part 21, which carries a wafer and a fluorescent adhesive η is arranged between the carrying part 21 and the first wafer 10a. The 7 M278068 fluorescent adhesive 12 covers the bottom and sides of the wafer 10. The function of the fluorescent adhesive 12 is as follows: 1. For diemunt / diebnd, for the first wafer i0a to be fixed to the supporting part 21; and 2. A white light source is generated after the colored light source generated by mixing the first wafer shirt is excited. On the first sheet, there are two positive and negative electrode layers, wherein the positive electrode layer is connected to the bearing portion U ', and the negative electrode layer is connected to another diode pin 20 by a metal wire. As for the second wafer 1%, it is also disposed on the carrier portion 2 丨, but the second wafer 10b 疋 is fixed on the carrier portion 21 by using the general colloid 11, and the positive and negative electrode layers are also sighed on the second wafer. Among them, the negative electrode layer is connected to the supporting part 2 with a metal wire 30, and the positive electrode layer is connected to another diode pin 20 with a metal wire 30. This creative color reading diode is sealed with a sealant (mold). ) After the completion, only the part of the diode pin ► 20 is exposed in order to receive working power, and the first wafer runs on the bottom surface of the mine with a V-light transmissive film indium tin oxide (indiumTin〇Xide; itq), Therefore, when the first chip receives power, it mainly generates a light source downward and a white light source is generated after the fluorescent adhesive 12 is excited. The second chip moves according to the color source of the chip and directly receives the working power. A light source emitting a specific color. Next, make a detailed description of the internal circuit of the two-color diode with a white light source. Please refer to "Figure 4" for a schematic diagram of the circuit of the two-color light-emitting diode with a white light source. M278068 In this work, the circuit type of a bi-color diode with a white light source, in which the direction of the first chip 10a and the second chip 1Qb are opposite to each other. When the power of Wei Zuo passes through the first chip 10a, When it generates a white light source, the second chip survey does not move, and when = two chip i0b receives working power to generate a light source, the first chip 10a does not move :, This creation has a two-color diode with white silk, The composition structure of the paste part is different from the conventional two-color diode with a white light source, so the appearance of the two-color diode has fewer pins than the conventional two-color diode, which reduces the production Cost, while using the two-color diode of the white light source to design the circuit, it can be more flexible.
