LED lamp beads lighting skills lines are integrated with extension, substrate, packaging, white light LED lamp beads, etc. Red, green, and blue LED lamp beads are III-V race compounds such as phosphorus, arsenic, nitrogen, etc. GAN) and other semi -guidance systems. 1. The price skills of LED lamp beads extended LED lamp beads for more than ten years have improved the growth process through the process of improvement. However, the nitrogen galfa gan of the mainstream white light lighting beads and the lattice of the lattice between the substrate and the unsatising coefficient of the heat expansion coefficient still causes a very high -bit error density density. For a long time, it has been to study the ability of LED lamp beads to reduce the density density and improve the crystal quality of the LED lamp beads to the most night. The extension of LED lamp beads is the focus department of LED lamp beads. The wavelength, forward voltage, brightness, or luminous volume of LED lamp beads basically depends on the material material. The extension skills and equipment are the key to manufacturing skills of the extension film. Metal organic material qi deposition skills (MOCVD) is an important essential of the growth of III-LED lamp bead specifications. The absence of the outer lattice is used as a non -glowing non -radiation composite center, which has a very main impact on the optical function of the device. LED lamp beads extension layout and extension skills research: The growth skills of LED lamp beads are pregnant, and a large number of subtitles and low IN components of the Ingan pre -mounted stress“Storage pond”Then heating up and growing the GAN barrier layer to improve the crystal quality of the barrier layer, the Ingaaln barrier layer or the growth stress of the growth of the grid. The quantum trap has a source area Ingan/Gan quantum trap. The source area is the focus of LED lamp beads. The key to growing Ingan quantum trap is to control the stress of the quantum trap, reduce the effects of polarization effects. The growth of LED lamp beads in the last years, the extension layer of LED lamp beads and extension skills have been mature. The internal quantum efficiency of LED lamp beads has reached more than 90%. However, in the study of power LED lamp beads, the quantum efficiency in invention of the year -old current injection is significant, and it is called the DROOP effect. The DROOP effect of GAN -based LED lamp beads is originally biased towards the localization of the carrier. The test invention accepts a wide quantum trap to reduce the density of the carrier and optimize the electronic interception layer of the P -shaped area. Other detailed skills in LED lamp beads extension layout and extension skills research are: The appearance of rough appearance LED lamp beads is delayed in appearance, which is commensurate with the transition angle to prevent the full reflection of the light. The difference between the refractive index and the packaging material is caused by the departure of the department's outlet will be reflected back to the extension layer. The process is directly punished for the disposal of the extension appearance, and it is easy to destroy the extension of the source of the extension, and the transparent electrode is more difficult to build. It is a feasible road to reaching the rough appearance through the transition of the extension of the external delay layer. Laboring skills LED lamp beads sapphire substrate laser stripping skills are based on GAN homogeneous extension and growth skills, coaxing UV laser irradiation base, melting transition layer peeling. To 75%, it is three times the traditional, and it has formed the production line. LED lamp bead pour chip skills. According to Lumileds company data, LED lamp beads of sapphire substrate growth rate of about 1.6 times. In addition to the front light of LED lamp beads, except for the front of the light, the outlet light of other faces reflects as much as possible back to the extension of the extension, and the ultimate promotion is from the front of the front. The micro -layout of the two -dimensional photon crystals of Lyric lamp beads can exceed the efficiency of leaping light. In September 2003, LED lamp beads with a diameter of 1.5 microns and 0.5 microns in height of 0.5 microns were built. Second, the chip base of LED lamp beads often uses chip base skills lines often use sapphire substrates, silicon carbide substrates, silicon substrate three -year night, as well as nitride, zinc oxide and so on developed. Met the requirements for the substrate material: The chemical invariability of the lumine bead substrate and the exterior membrane layer is matched. The substrate material must have a good chemical invariability. The chemical reflection of membrane breeding causes the quality of the vertical membrane to land; LED lamp bead substrate matches the thermal expansion coefficient of the vertical membrane layer, and the thermal expansion coefficients are different. The destruction of the device is destroyed; the layout of the LED lamp base and the exterior membrane layer is matched. my country's LED lamp beads silicon base skills have suffered from skills breakthroughs, and they are growing up to the application of propertyization of the year -end. At present, only sapphires and silicon substrates that have been used for commercialized GAN -based LED lamp beads are. Other substrate materials that can be used for GAN -based LED lamp beads are separated from property and commensurate with GAN homogeneous substrates and ZNO substrates.

Compared with the traditional incandescent lamp, there are several advantages of the light -sensitive diode. First of all, there is no filament of the Guangmin diode, which eliminates the possibility of burning, so the service life is longer. In addition, the small plastic bulbs of the Guangmin diode make the light -sensitive diode more durable. The current electronic circuit is also easier to use. The glowing process of conventional incandescent lamps contains a lot of heat, which is a waste of energy. If you do not use the light as a heating device, then most of the effective current will not directly generate visible light. The calories emitted by the Guangmin diode are very small. Relatively speaking, the more electrical energy is directly glowing to largely reduces the demand for electrical energy to a large extent. So far, due to the use of advanced semiconductor materials, Guangmin diodes are still too expensive in most lighting applications. In the past 10 years, the price of semiconductor devices has dropped sharply. However, under a broader application, Guangmin diodes are a more cost -effective lighting option. In the near future, Guangmin diodes will play a greater role in world technology. LED is composed of PN, like ordinary diode, and has one -way conductivity. After adding a positive voltage on the Guangmin diode, the electron in the nage in area N from the P area and the electron in the P area from the n area, and the electronics and the empty cave in the PN area in the PN knot are in several microns near the PN knot, respectively Compound, produce spontaneous radiation light. Depending on the difference in semiconductor materials, the energy status of electronics and cavities is also different. How much energy is released when electronics and holes are compounded. The more energy it releases, the shorter the wavelength of glowing. The commonly used diodes of red, green or yellow.

UVLED has been used in various industries. The light sources can be divided into three categories according to the shape, point light sources, line light sources and facial light sources. Here is the product of Zhuhai Tianhui as an example. Let's briefly introduce the light source. Its composition is mainly 4 parts, controller, UVLED point light source illuminating head, UVLED light light bead, concentrated lens, a controller can bring up to 4 point light sources to illuminate the head, UVLED point light source illuminates are distinguished according to the diameter of the light spots. Usually 4mm, 6mm, 8mm, 12mm, the smaller the light spots, and the higher the intensity of the irradiation, it is mainly used in small -sized UV curing. UVLED point light sources have the following characteristics: 1. UVLED point light sources are small in volume, which is easy to carry and move. 2. UVLED dot light sources have no consumables. The cost of use and maintenance is low. Unlike traditional mercury lamps, the lamp tube is replaced regularly. 3. UVLED dot light source is controlled by touch screen control, and the operation and parameter settings are simple. 4. UVLED point light sources do not need to be warm up, and can directly output 100%power. 5. UVLED dot light sources use high -energy ultraviolet LEDs with high output light power. For example, the point light source with a diameter of 4mm, the output power reaches 9000MW/CM2.
