The semiconductor wafer consists of three parts, one part is a P-type semi-conductor, in which the hole dominates, and the other end is an N-type semiconductor, where f is mainly electron, and the middle is usually a quantum well of 1 to 5 cycles. When a current is applied to the wafer by a wire, electrons and holes are pushed into the vector sub-well. In the quantum well, electrons are combined with holes, and then energy is emitted in the form of light=, which is the light-emitting diode. The principle of body luminescence. The wavelength of light, which is the color of light, is determined by the material that forms the P-N junction.

The light-emitting diode 21 and the metal dome 22 are located below the light guide column 10. The light-emitting body 1 is mounted in the casing 2 by Surface Mounted Technology (SMT). The light-emitting diodes 21 are available in various colors. Four pins are drawn from the light-emitting diode 21 and the metal dome 22 in the casing 20. The light-emitting diode 21 is connected between the stitch 1 and the stitch 2, and a switch for opening the light-emitting diode 21 is connected between the stitch 3 and the stitch 4. The abutting portion 11 of the light guiding rod 10 abuts against the metal dome 22, and the pin 3 and the pin 4 communicate with each other, and the light emitting diode 21 emits light to illuminate the light guiding rod 10. 4 201042685 Please refer to Fig. 2', a second preferred embodiment of the light-emitting diode switch of the present invention. In the manner, six pins are drawn from the light-emitting diode 21 and the metal dome 22 in the casing 20. There is a light-emitting diode 21 having a first color connected between the stitch 1 and the stitch 2. A light-emitting diode 21 having a second color is connected between the stitch 3 and the stitch 4, and between the stitch 5 and the stitch 6 A switch for opening the light-emitting diode 21 is connected. The light-emitting diode switch controls the light-emitting diode 21 ' by a Pulse Width Modulation (PWM) to cause the light-emitting two-pole body 21 having the first color to emit light or The light-emitting diode 21 of the second color emits light, or the light-emitting diode 21 having the first color and the light-emitting diode 21 having the second color simultaneously emit light to generate a third color. Referring to the third preferred embodiment of the present invention, the light-emitting diode 21 and the metal dome 22 in the housing 20 are drawn by six pins. The housing 2 is provided with three light-emitting diodes 21 each having a red, green and blue color. The light emitting diodes ^ are connected between the stitch 1 and the stitch 4, between the stitch 2 and the stitch 4, and between the stitch 3 and the stitch 4. The stitch 4 is a common stitch. A switch for opening the light-emitting diode 21 is connected between the stitch 5 and the stitch 6. The light-emitting diode switch controls the light-emitting diode 21 by a pulse width modulation technology, so that the light-emitting body 21 emits red light, green light, blue light or other colors formed by the three colors and σ Color light.
