In recent years, more and more scientific research units are consulting Tianhui's UVLED light sources. Among them, there are many Chinese Academy of Sciences and some universities. Previously, a teacher of a well -known college purchased UVLED of Tianhui. When asked what they used to do with UVLED, they told me proudly: use UVLED to study the variation of semiconductor silicon molecules under ultraviolet rays. It is said that it is possible to be possible Growing. Why not use traditional ultraviolet rays? Such as mercury lamps or halogen lamps?

When it comes to LED lights, I believe everyone will not feel strange. But people who know the LED light source module may be less and less. To put it simply, the LED light source module is to arrange the light -emitting diode in accordance with certain rules and then encapsulate it, and then add some waterproof treatment. It sounds simple, it will make people feel that this product is very cheap, and there is no technology to say at all. But the price of the LED light source module is not its main advantage, and its advantage is as follows: 1. Small volume. The LED light source module is relatively light, easy to shape, and is not limited by size. Because the volume of the LED light source module is very small, there is no need to worry about stitching and use during the installation process. 2. Easy maintenance. The LED luminous characters are used as the LED light source module as a light source. It has a long service life and will not be easily damaged. If a problem occurs, it is only necessary to replace it. 3. Uniform luminescence. After the LED light source module is assembled into the light, the color of the entire font will be very bright, and the phenomenon of light spots and glowing will not appear evenly. It is easier to attract the attention of different advertising groups. 4. Low cost. Due to the increasing popularity of LEDs, the current price of LED lighting has a certain low price. However, as a cost -effective advertising lighting product, LED light source modules are more likely to exert its advantages. Not only its later maintenance costs are much lower than other advertising lighting fixtures, but the current price is very affordable. Many people have been affordable. Consumers are accepted, and product use is also very wide. 5. High brightness. The brightness of the LED light source module is very high. I believe this does not need to do too much explanation. The LED light source module uses LEDs as a light source, and LED is a cold source. Most of its energy will be converted into light, and it will not be transformed into heat like incandescent lamps. Therefore, its brightness is higher than ordinary lamps. The promotion effect is better. 6. Energy saving and safety. I have also said before that the LED light source module is small, so L's power is also very small, and the power consumption is low. Due to the low output voltage, it is more secure and energy -saving, more suitable for the use of the masses. Another point is that the LED light source module is waterproof. It is also possible to use it under severe weather such as rainy days. The LED light source module is widely used in LED products. Its color is bright, bright and energy -saving and safe. Slowly let it become the "net red" in the LED industry. It is so popular with the majority of groups, not because of the price of LED light source modules, but the various advantages of the LED light source module have been recognized by the public.

With the gradual development of LED lamp bead technology, LED lamp beads have entered the mature lighting market. However, the development of LED lamp beads has been affected by the problem of heat dissipation at a very level. For LED lamp beads, the heat dissipation problem of LED lamp beads has become a serious problem restricting its development. The LED lamp bead semiconductor refrigeration technology has the upper hand, small volume, not using refrigerant, simple structure, no noise, and stable functions, etc., with the improvement of LED lamp bead semiconductor material technology and progress, and high -heat electric conversion materials It is found that coaxing semiconductor refrigeration technology to solve the heat dissipation problem of LED lamp beads will have very realistic significance. The reasons for the heat generated by LED lamp beads and the effects of heat on the LED lamp bead function of LED lamp beads. Under the front voltage, the electrons are suffered from the energy of the power. Under the drive of the electric field, the electric field formed by the PN from N area to the N area to In area P, the cave in the electron and P area will compound. LED lamp beads have the energy that is higher than the Prices of the P area than the Prices of the P area, the LED lamp beads will return to the low energy state when the LED lamp beads are compounded. However, only 30%to 40%of the photons released by LED lamp beads are converted into optical energy, and 60%to 70%of the remaining 60%to 70%of LED white LED LED lamp beads are transformed into armal energy at a point vibration. Since LED lamp beads are semiconductor luminous devices, and semiconductor devices change with temperature changes, their inherent characteristics will change significantly. The increase in temperature of LED lamp beads temperature will cause changes and attenuation of the function of the device. This change is important to reflect the following three aspects: 1. Reduce the external quantum efficiency of LED lamp beads; 2. Shorten the life of LED lamp beads; 3. The main wavelength of the LED lamp beads emit a light shift, which leads to the color of the light source. Offset. The power LED lamp beads are generally input more than 1W. The heat generated by LED lamp beads is very old, so the problem of solving the heat dissipation of LED lamp beads is the current emergency. The article comes from the cold hat LED lamp bead http: //

Now many people often "over -use their eyes" due to factors such as 3C products and working durations, so they gradually start paying attention to eye protection. A new study in the UK pointed out that in the morning, using "dark red LED light" to illuminate the eyes for three minutes, the eyes can "restore vitality". According to the "Scitech Daily" report, the research team of the University of London (UCL) discovered that in the morning, the eyes were exposed to the eyes with a wavelength of 670 nanometers (NM) in the morning, which can effectively stimulate the energy generated in human retina to generate energy. "Merkellar cells" and help recover the vitality and acuity of the eyes. According to reports, the experiments invited 20 subjects between the ages of 34 and 70 and had no eye diseases. After lighting in the morning and afternoon, they found that if in the afternoon test Improved; but if the eyes are illuminated between 8 am and 9 am, the subject's "color discrimination" can be improved by 17%. The effect can last up to a week. In this regard, the research professor Glen Jeffry explained that due to the increase of age, the cells in the retina of the eyes will gradually age, and the speed of this aging is the "tricephosphosine adenosine (ATP (ATP (ATP generated in the cell mitochondria (ATP (ATP (ATP ) "And enhanced cell function began to decline. The previous research pointed out that the light between 650 and 900 nanometers (NM) can activate mitochondria and improve its "work efficiency". Therefore, the principle of lighting seems to be "wireless charging" with the eyes and can restore part of the function of some photoresu cells. Due to its simple principle and no security issues, Jeffrey is also developing home treatment instruments that are cheap and easy to use to provide more "affordable ophthalmic therapy" for patients with color disciral decline.

How much do you know about glowing diodes? Today's light -emitting diode market demand is wide. Those who are used in street lights, medical devices, car lights, cameras, power indicator lights and other fields are all involved. Today, the editor mainly wants to explain how to light up the light -emitting diodes. Take the indicator light as an example; when our luminous diode is connected to AC 220V, it is used as a power indicator, and the simplest way is to connect a current -limiting resistor. According to the type of light emitting diodes the size of. The general light-emitting diode is 2.8-3.4V, the materials for various colors are different, and the voltage is different. Now the high brightness light emitting tube, the current 10mA is already bright enough. For general light emitting diode, the working current value is 1mA-15mA. The specific brightness can be changed by adjusting the size of the current limit resistance. The main principle of light emitting diode is actually to form a certain potential barrier through the end voltage of the PN knot. When the position of the positive bias voltage decreases, most of the carrier in the P area and the N area spread to the other party. Because the electronic migration rate is much greater than the air acupoint migration rate, a large number of electronic spreads to the P area, forming an injection of a minority carrier of the P area. These electrons are compounded from the cave on the price, and the energy obtained during composite is released in the form of light energy. This is the principle of PN knot glow. The above is some of the lighting explanations about the light emitting diode today, which is summarized by the editor. If you want to know more information about the light -emitting diode or buy a product, you can directly contact the online customer service, or dial the contact phone for consultation.
