Referring to FIG. 2, the LED package structure 200 of the present embodiment includes a flexible circuit board 210, a protection sheet 220, at least one LED chip 230, and a soft filler 240. The number of the light-emitting diode wafers 230 in this embodiment is exemplified by three, but may be more or less. The flexible circuit board 210 has a wiring layer 212. The protective sheet 22 is disposed above the flexible circuit board 210. The LED chip is disposed between the flexible circuit board 21A and the protection sheet 220, and is electrically connected to the circuit layer 212. The soft filler 240 is filled between the flexible circuit board 21A and the protective sheet 220. The protective sheet 220 and the soft filler 240 may be made of a transparent material. Referring to FIG. 1 , in the prior art, the LED chip 11 needs to be wire bonded to the lead frame 11 , and then sealed by the encapsulant 14 , and finally assembled to the printed circuit board 5G. Referring to FIG. 2 , In the light-emitting diode package structure of the embodiment, the light-emitting diode chip 23 is directly assembled to the flexible circuit board 21G, and the light-emitting diode wafer is further processed by the protective sheet 22 () and the soft filler 240. 230 sealed. Therefore, the light-emitting diode structure 200 of the present embodiment has a wealth of points and can save process costs. The conventional light-emitting diode package structure of 1 uses an irrevocable ί7 'way board 50 and cannot be attached to non-planar objects. Person: Replace the brush circuit board 5〇 with a flexible circuit board to solve the aforementioned problems. The second is due to the soft circuit board and the hard and ribbed two = connection, the touch time is extremely capacity _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The main components of the structure 200, such as the flexible circuit board training, the protection 2twf.doc/n 200935621 sheet 220 and the soft filler 240 are all highly flexible, so that the LED package structure 200 can be curled and easily stored in bundles. When the light-emitting diode package structure 200 is to be attached to a non-planar object, an excellent fit can be easily obtained. In addition, since the bonding degree is better, the LED package structure 200 can be attached to a heat sink (not shown) to obtain a higher thermal conductivity. For example, the circuit layer 212 of the flexible circuit board 210 can be formed on a substrate 214' and a portion of the circuit layer 212 can be covered by a solder mask (not shown). The material of the substrate 214 is, for example, a polyester resin (mylar) or a polyacrylamide (p〇iyjmide). The circuit layer 212 may include a heat dissipation line 212a for conducting heat in addition to the line for conducting electrical signals. At this time, the light-emitting diode chip 23 can be placed on the heat-dissipating line to be quickly discharged by the heat-dissipating line 212a. In the present embodiment, the LED array 230 has an opposite active surface 232 and a back surface 234, that is, the active surface 232 has electrodes (not shown), and the back surface 234 has no electrodes. Of course, electrodes may also be present on both surfaces of the LED wafer 230. The light-emitting diode wafer is electrically connected to the wiring layer 212 by a wire 250, for example, by a bonding technique. However, the light-emitting diode wafer 23 can also be electrically connected to the wiring layer 212 by bumps (not shown) by flip chip bonding. Alternatively, the LED chip 230 can be electrically connected to the wiring layer 212 using bumping techniques such as wires and bumps or other suitable techniques. Alternatively, a heat transfer material 26'' may be disposed between the back surface 234 of the light-emitting diode wafer 230 and the heat dissipation line 212a to enhance the thermal conductivity. The heat conductive material 260 200935621 2twf.d〇c/n is, for example, silver glue or other suitable heat conductive material. Although the light emitted by the LED chip 230 is ultraviolet light or other non-final desired light, a phosphor 27 can be disposed between the flexible board 210 and the protective sheet 22, and covers the light emitting diode. The body wafer 23 is. The action of the bismuth material 转换 converts the light emitted by the illuminating diode 230 into the final desired light. Therefore, the glazing 270 is selected in accordance with the principle of being compatible with the illuminating body wafer 230. Additionally, the soft filler 240 can be a raytail, epoxy or other suitable material. In addition, the LED package structure 200 may further include at least one spacer 280 ′ disposed between the flexible circuit board 21 〇 and the protection sheet 220 to further maintain the flexible circuit board 21 by using the spacer 280 having a relatively high hardness. The proper spacing between the sheets 220 is protected. Furthermore, the light emitting diode package structure 200 may further include an adhesive layer 290 and a release film 295. The adhesive layer 290 and the LED array 230 are disposed on different surfaces of the flexible circuit board 21, respectively, and the adhesive layer 290 is disposed between the ❾ release film 295 and the flexible circuit board 210.
