A lens 18 enclosing the luminescent wafer 12 is supported on the step 36. The two 7 M361724 grooves 38 and 39 are coupled to each other, and the first groove % and the second groove 39 shown in FIG. 7 are trapezoidal grooves, and the first groove % and the second groove ^ face the center of the inverted cup 14 The inner side of the groove of the shaft is a beveled surface, which can appropriately reflect the light, improve the light extraction efficiency, and change the light exit angle. The second groove ^ is close to the hair. The groove wall 392 of the optical wafer 12 is a straight wall, and the upright groove wall 392 ^ can be regarded as a convex ring extending along the axial direction of the reflective cup 14.

Each of the collars has the same function as the slot wall 282 of the second embodiment. Figure 9 shows - = 39b, that is, the v-groove and the inner side of the groove of m are both inclined, and the 'V-shaped groove 39b is inclined toward the outer side of the groove of the center axis of the reflector cup 14, thereby reflecting the light Hk , efficiency, and changing the angle of light. The two v_3d are first connected to form a zigzag groove structure, and can also be seen as a zigzag groove structure with a better moisture-proof effect.凊 Refer to Figure 10 for the LED package provided by the 篦 杳 杳 杳 = =. The package structure 40 includes a carrier 41 and a reflector cup 44 of the light-emitting chip 12 body. The carrier 41 and the reflector cup are formed into limbs.
