[Prior Art] The hair has two advantages: small size, long life, low power consumption, and monochromatic illumination.

Shout. Its typical riding style is shown in the figure. • Because of the substrate on which the light-emitting diode is fabricated – sapphire is an insulating material, and the layered material is a semiconductor material. Therefore, the manufacturing process of the light-emitting diode and its use of the *'s are very sensitive to static electricity, and the components are not noticed. Permanent W. Other data show that the blue and green diodes (4) electrostatic capacity phase difference & the static electricity on the human body can only withstand (10) ~ modest overvoltage. This is the traditional to solve the problem of static paste, the operator needs to wear Electrostatic ring to prevent damage to related parts. In order to solve the static problem of the above-mentioned light-polar body, the castings of the patents Nos. M314427 136175, 261831 and the Chinese patent No. 88 all mention the use of Zener diodes to improve the static electricity of the components. The problem, but because the Zener diode has directionality and read a large amount, it is actually a device that uses the direction of the grain touch, and the Zener diode is packaged in the small two difficulty degree. Actual use is relatively small. U.S. Patent No. 6,593,597 proposes to use a light-emitting diode shim-crystal process to directly form a diode on a red wafer, and then to have a light-emitting diode and a diode on the same wafer when the wafer process is completed. Although it can solve the directional problem of the packaging process, because the crystal size is small, it is difficult to make two different products in the same - crystal strong, although theoretically feasible, but in the continuous production, the insect crystal process and subsequent wafers The problem of the alignment of the process, there is a very high IU this 'in theory' this kind of structure should be able to be manufactured, but the production of 疋 相当 is quite difficult to achieve. Force and oxygen wave X-wave absorption||Excellent electrostatic absorption capacity and component/directionality' plus the current commercial minimum size has reached _ specification, is a fairly good electrostatic device, it has been described Reliance on mobile phones, digital cameras, PM, notebook computers and other products. In addition, the polymer static material is coated with a polymer material such as A1, Ag, Ni or the like, or the z f element is not electrostatically absorbed, and can withstand an electrostatic voltage of more than 8 kV. The invention adopts the above-mentioned electrostatic protection element and blue light, green light, white light and purple light material Lai _ she class to protect the electric absorption capacity to absorb static electricity, to protect blue light, green light, white = 1 ^, so that the whole light two The polar body has excellent electrostatic protection capability and can reach the above electrostatic absorption capacity. Because the laminated zinc oxide surge absorber and the M314427 are installed, the component itself is not directional, so in the case of the light-emitting diode component sealing element, the component is decorated with a wave absorption 11 and a polymer electrostatic protection plug. The direction of t is _, so it can speed up the component assembly rate. In addition, due to the fact that these two products are mass-produced and the components are inexpensive, the price of the light-emitting diode components of the overall assembly ® wood has little influence. [New content] The real (4) main reversal is in the wafer is a general insertion type (Dip I first-polar body in the human layer of Wei-Zinc surge absorption 11 or polymer electrostatic protection components, and insulation materials For example, the blue, green, and violet crystal grains of the substrate, such as turning stone, oxygen scale, nitrided, and bismuth sulphate, are directly connected together by the same type, using the 0-type spur wave (4) or the polymer gift. The resistivity of the medullary component is sensitive to static electricity, and the static electricity is directly led to the grounding loop. Thus, the blue light, the county, the violet light, and the self-extracting light-emitting diode can be greatly improved, and the chip is not mounted. The type of surge absorption or the electrostatic protection capability of 100.V before the polymer type electrostatic protector improves the electrostatic protection ability above 8KV. The wafer type surge absorption @ or the polymer type electrostatic dragon itself has no direction. Sex, therefore, the components are assembled without regard to the directionality, which can greatly reduce the cost of the two-component equipment. In addition, because the components are cheap, a wafer-type surge absorber or a 〒-type electrostatic ray is applied to the entire illuminator. Polar body manufacturing The effect is not significant. · Figure 2 is a schematic diagram of a light-emitting diode connected in parallel to a wafer-type surge absorber or a polymer type static reduction. 3Q is a light-emitting diode, and 20 is a wafer-new absorption thief. It is a polymer static Wei protection anti-static component. In the figure, M314427 two-chip type large wave absorption n or polymer type static electricity has two-way characteristics. When the normal voltage is added to the light-emitting diode, the s piece ^ white special Receiver or polymer type static example crying V 'listening to the sun type big wave absorption first __ i, $ (10) is missing in (four) 辄 state, so the current mainly flows through the light-emitting diode, but when there is a high electrostatic voltage ~ On the top of the flip-flop, the wafer type surge absorber or the polymer type '% protector is in low-resistance makeup, + sink or polymer type static electricity, and the flow mainly flows through the wafer type. The spurt absorbing "also state's can protect the luminescent diode. In addition, when 遂^ j V2 is not too big, the resistance of the light-emitting diode and the electrostatic protection part is quite large, so it flows through two. The pole __flow is quite small, but when the anti-electricity: electrostatic conduction is quite high, W wave (four) or polymer; static 2 = The resistance value of the temple element is in the low-resistance state, and the current mainly flows through the static electricity. Your mouth is only a piece of cake. So, add a dream, 丨 丨 丨 丨 + ^ + ^ wave absorption 11 or polymer type electrostatic protection mouth 4 Qian Baoda components can achieve the function of two-way protection.
