New Description: [New Technology Field] This new type is about a light-emitting diode package structure, especially a long-lasting light-emitting diode package structure. [Prior Art] The existing light-emitting diode device must be continuously illuminated by applying a voltage to continuously provide illumination service. That is to say, as long as the power of the light-emitting diode is turned off, the lighted "diode device is immediately annihilated and cannot continue to emit light. Thus, if the light-emitting diode device is required to continuously provide illumination service, it is necessary to provide power for a long time to ensure that the light-emitting diode device can continue to emit light. In general, devices that provide a large amount of power are inevitably batteries, capacitors, or utility wires. However, regardless of the form of the device that supplies a large amount of power, it is bound to increase the use space cost, energy cost, and material cost. The maintenance cost of the disk is not helpful for reducing the cost. . 1. In addition, the existing light-emitting diode devices that require multi-color lighting industry applications (such as advertising and decorative lighting) require multiple colors of light-emitting diodes to be used to not only reduce costs, but also increase wiring. The difficulty of the calculation. It can be seen that the above-mentioned existing light-emitting diode device obviously still has ff and defects, and it needs to be further improved, which is one of the current important research and development topics, and has become an urgent target for improvement in related fields.

In addition, the long-lasting LED package structure of the present invention emits different types of long afterglow phosphors in the corresponding package bodies by at least two kinds of LED die light, once the LED chips are no longer powered. After the luminescence is stopped, at least two kinds of long afterglow phosphors of the new type of long afterglow LED package structure can also provide multi-pattern color mixing before the fluorescence decays. BRIEF DESCRIPTION OF THE DRAWINGS The spirit of the present invention will be clearly described in the following description and the detailed description of the preferred embodiments of the present invention, which can be modified and modified by the teachings of the present invention. It does not depart from the spirit and scope of the present invention. Referring to Fig. 1, Fig. 1 is a side view of a novel long afterglow LED package structure 100 in accordance with an embodiment. The long afterglow LED package structure 100 of the present invention comprises at least a substrate 200, a first LED die 300, a second LED die 400, a first encapsulant 500 and A second encapsulant 600. The first light emitting diode die 300 is fixed on the substrate 200 and connected to the substrate 200 by two first wires 310, so that the first LED die 300 can be electrically connected to the substrate 200 by the first wire 310. Docked. The first light-emitting diode die 300 emits light having a first light-emitting wavelength. The second LED body 400 is also fixed on the substrate 200, spaced apart from the first LED body 300, and connected to the substrate 200 by two second wires 410, so that the second LED is crystallized. The particle 400 can be electrically connected to the substrate 200 by the second wire 410 7 to have a second light output. The first light emitting diode die 400 can emit light having a long wavelength. The ruthenium colloid 500 coats the first-light-emitting diode die 300 and the green guide 310. The first - material camp light powder 51 〇 1 2 ^ gel body distribution has a number of - long afterglow _ and the second wire: 〇; colloid 600 coated second light-emitting diode grain dior encapsulated colloid 600 A plurality of second long afterglow phosphors 61〇. The flute _e, b second long afterglow phosphor 610 is different from the first long afterglow phosphor 510, and a gap G is maintained between the encapsulant 600 and the first encapsulant 500. In this embodiment, the long afterglow LED package structure 100 further includes a power supply 800. The power supply 8〇〇 is electrically connected by the substrate 2, a light-emitting diode die 3〇〇 and the second light-emitting diode die 4〇〇, and thereby controlling the first light-emitting diode crystal The granules 3 〇〇 and the second illuminating diode dies 400 are bright (ie, illuminating) and extinguished (ie, not illuminating). In this manner, when the power supply 800 supplies power to the first LED die 3 and the first LED die 400, respectively, the first LED body 300 and the second LED are used. The crystal grains 400 respectively emit light, so that the light having the first light-emitting wavelength is photoexcited and reacted with the first long-lasting phosphor powder 510 in the first encapsulant 5 , to generate a fluorescent light having a third emission wavelength. The light having the second light-emitting wavelength is photoexcited in the second encapsulant 6 (8) and the second long-lasting phosphor 61〇, and the fluorescence of the peak of the four exit wavelengths is generated. , the first vice versa when the power supply 800 stops supplying power to the first LED 曰 300 and the second LED dies 400, and the first private _ yang & dies 300 and the second illuminating When the polar crystal grains 400 stop emitting light, the fluorescent filaments excited by the first long-lasting phosphor powder 510 in the encapsulating colloid 500 will retreat, and the fluorescent light having the third optical wavelength will gradually disappear. Similarly, the second long glow 361 in the second encapsulant _: the excited luminescence requires a light decay time to gradually return the glory with the fourth exit wavelength. In this way, the two kinds of fluorescence in the recession can be gradually mixed into the glory of multiple colors. In the first package colloid 500, only a long afterglow glaze powder (such as the first-long afterglow glory powder) and one type of x, one-pole crystal (such as the first light-emitting diode) There is only another long-lasting phosphor powder (such as the second long afterglow glory 610) and another light-emitting diode (such as the second light-emitting diode crystal) in the second encapsulant 60G. Grain 4〇〇). Therefore, since the first encapsulant 5 〇〇 and the second encapsulant _ are maintained at a reasonable spacing G, the light of the first luminescent diode 3 可 can fully interact with the first long afterglow glory 51 〇 After the light of the expected color is converted, the light interacts with the light output from the second slit 6 ,, so that the light of the first light-emitting diode in the first encapsulant 5 吁 is avoided. Fully interacting with the first-long afterglow phosphor powder 51〇 acts with other long afterglow phosphors to produce a color deviation on the mixed light. Referring to Fig. 2, Fig. 2 is a side elevational view of a novel long afterglow LED package structure 101 according to another embodiment. In another embodiment, the long afterglow LED package structure is a surface mount type (SMD) long afterglow LED package structure 〇1. When a plastic base 110 covers the substrate 201, the reflective opening 111 of the plastic base 11 turns out of one of the solid crystal faces 202 of the substrate 201. The first light-emitting diode die 300 and the second light-emitting diode die 4 are fixed on the solid crystal surface 202 of the substrate 201, and then connected to the first light by the first wire 31〇. The diode body 300 and the positive and negative electrodes on the substrate 2〇1 (not shown); the second light conductor 410 is connected to the second light emitting diode die 4〇〇 and the positive and negative electrodes of the substrate 201 (not shown) ).
