2835 White Light Patch LED Lamp Beads 7LED Lamp Beads What Are the Major Advantages?

Due to the light power of a single UVLED lamp bead, or in order to meet the needs of market differentiation, several UVLEDs need to be combined in a certain way (such as UVLED face light sources, UVLED wire light sources, etc. Equipment), and give a suitable driving solution. This article introduces the connection method of UVLED. Connecting connection method: As shown in Figure 1, the connection connection is connected to the end and end of each UVLED lamp bead. According to the law of KCL, the current flowing through the UVLED pass is exactly the same. It is worth noting that the number of lamp beads connected in series should be evaluated according to the voltage capacity of the power supply source. Connecting connection method: As shown in Figure 2, the characteristics of the connection connection are that each UVLED is connected in parallel according to the same polarity. According to the KVL law, it has the same working voltage. same. The mixed mode is shown in Figure 3. The mixing mode is to implement the series and parallel modes at the same time. First connect several UVLED lamp beads, and then connect the first tank of the lamp beads in parallel connection. This connection method has the characteristics of series and parallel connection at the same time. In practical applications, there are usually a variety of connection combinations. The power supply method and cost -effectiveness of the UVLED light source should evaluate the connection method of UVLED.

In the work, the UVLED curing machine will be converted into light energy and thermal energy, and most of the latter. If the thermal energy cannot be dispersed in time, the lamp beads will work in high temperature. The larger, the better, so good heat dissipation is also an important guarantee for UVLED curing function to work normally for a long time. We take the product of Tianhui as an example to introduce two commonly used heat dissipation methods. 1. Fan heat dissipation is a radiator on the copper -based plate of the lamp beads. The heat sinking fan blows away the heat. This method is mainly aimed at the relatively sparse light source of the lamp beads. The main disadvantage is that the fan work will have noise. 2. Water -cooling method, use water -cooled machine, circulate through water, and take away the thermal energy of the light source. This method is used for light sources with dense lamps. It is difficult to achieve the effect.

The fixing of lens glue needs to be used in the optical industry with UVLED curing light sources. At present, the glue lens is generally combined with two to three lenses. The fixation of the lens is bonded using UV glue, and then the UVLED curing light source is irradiated to complete the curing. 镜片涂上UV胶水之后在UVLED光固化设备的高強度紫外线光照射后产生活性自由基或离子基从而引发聚合交联和接枝反应使UV胶在数秒内(不等) Converted from liquid to solid state. At this time, the lens can be firmly fixed in a position that needs to be fixed. The lens glue lens glue is made of two single -sheet lenses through the glue. The performance of the compound color (white light) imaging is much better than the single lens performance. The color of the coloring differential lens is combined with two different lenses of the materials, which corrects the color of the glass. The glue currently used in lens glue is mainly UV glue, and it needs to be irradiated through the UVLED curing light source to complete the solidification.

UVLED solidified light sources (here contains UVLED facial light sources, UVLED wire light sources, UVLED dot light sources) The mode of adjustment of lighting power is PWM methods and simulation methods. This article discusses some concepts of these methods. Make UVLED periodic diversion and cut off. This method is called pulse width modulation (PWM). During the turnover, the current is the rated value. The percentage of the turnover time is called duty cycle (DC). The average current of the UVLED is equal to the product of the current and the duty ratio of the current to the duty ratio when the UVLED is turned on. In practical applications, according to the characteristics of UVLED ultraviolet light, the frequency of PWM is generally greater than 60Hz. Usually use digital chips for PWM modulation. UV curing devices such as UVLED light sources produced by Tianhui use a new generation of digital modulation chips. Reliable continuous work in a complex environment.

Today, UVLED irradiation and applications are becoming more and more extensive. Different companies have different design concepts and design methods. How to evaluate the quality of a UVLED irradiation device, we think there are mainly the following indicators: 1> The conversion efficiency of electricity and light is the conversion efficiency of electricity and light. Look at the ratio between our equipment consumed and the effective power of the light source output, the LED is the energy -saving light source, the higher the ratio, the higher the efficiency of the electricity power conversion. Electric large, low electricity conversion efficiency. 2> The uniformity of the distribution of light spots, uniformity refers to the difference in the strength of each point in the range of the valid light spots. The smaller the difference, the better the uniformity. 3> The life of the light source, the LED life is relatively long, but in practical applications, various design and environmental factors may destroy the light source, the longer the life span, the more reasonable the design of the device design. 4> The efficiency of heat dissipation and the uniformity of heat dissipation, because many lamp beads gathered together, which will emit a lot of heat. If the heat can not be distributed in time, it will have a fatal effect on the equipment and products. 3 methods: heat sink and water cooling. 5> The stability and reliability of the circuit control system. If this part is not done well, those with light may often fail, affect efficiency, and may destroy the light source, and even cause the terrible consequences of the fire.

TIANHUIUVLED solid machine also has many application scenarios in the LCD industry. Among them, there are mainly the following four application points. Now let Tianhui take you one by one to understand: 1. During the LCD production process, the purpose of the light carvings is according to product design requirements. , Apply light glue on the ITO conductive glass, and perform ultraviolet light exposure, that is, selective irradiation, which chemically reacts the photoresist in the optical part of the light, which changes the solubility of this part of the film in the developed solution. Then use the protective effect of photoresal glue to selectively chemically corrode the ITO conductive layer, so as to obtain a graphic that completely corresponds to the mask on the ITO conductive glass. Second, UV LED modification (surface quality change) is currently used in the production process of LCD display STN, which is mainly used in membrane treatment technology. It is very effective for improving the tightness between the membrane. Plastic membrane layer, TOP coating and PI coating, etc. Third, UV LED's solidification of LCD sealing and blocking glue. The empty liquid crystal box that does not irrigate the liquid crystal must be fixed. When using a sealing rubber, the solidification process conditions should be made reasonably according to the performance of the UV glue used to avoid solidification with excessive ultraviolet light to prevent adverse effects on LCD. Because the decomposition of UV light on LCD materials will increase the power consumption current of the device. The UV curing machine is added to the resin in a special formula. After the UV coatings radiate through the ultraviolet radiation, the chemical reaction is generated after attracting high -intensity ultraviolet light in the UV -optical curing equipment. Sending a free ionic or ion, these free groups or ions with double bonds in the premature or unsaturated monomer of the ionic group have a cross -linking response to form a single group, which causes aggregation, cross -linking, and branches. In a few seconds (no), from liquid state to solid state. This change process is called UV curing, but this process is not over, and there is a post -curing process. Therefore, the quality of the product after the test must be performed. Fourth, UV LED cleaning UVLED light cleaning technology is to use the optical oxidation effect of organic compounds to remove organic substances that are attached to the surface of the material. UVLED emits ultraviolet light in a special band, which reacts with the optical agent inside the organic compound. Therefore, if you want to use this process, you must choose the correct UVLED spectrum energy and the appropriate optical agent material. TIANHUI can provide sample machines for free testing with customers, ensuring that customers have zero investment in the early stage.

The LED light source module is divided into two parts, one is a variety of LED screens specifically for outdoor, mainly used for display and backlight; the other is specifically used for LED lighting classes. Here we mainly talk about LED light source modules. The light source modules used for LED lighting are divided into two parts: DC module and AC module. DC module is Direct Current English abbreviation, AC module is to exchange Alternating Current English abbreviation. Different modules are different from the lamps. The DC modules are divided into constant current modules and constant voltage modules. They need to be applied to the lamps together with the driver. The AC module is different. Municipal Electric Application on Lantern. The constant stream module, that is, the module board current is constant, the voltage can be adjusted appropriately. The constant voltage module is the fixed voltage of the module board, and the current can be adjusted at will. At present, 12V, 24V, and 48V are more common. The AC module already has its own power supply system, which can be connected directly to the municipal electricity. Different modules are applied to different lamps. The constant stream module is mostly used on fixed and separately used lamps; constant pressure modules are mostly used for combinations, infinite stitching lamps; AC modules can use various lamps, focusing on Cost consideration. The AC module is directly connected to the market. Many users are worried about safety and do not dare to use it. In fact, as long as the structure is processed, it is very safe to use the lens or colloid to protect the high voltage part and not let people contact With the improvement of technology, this aspect can be well avoided; and because the DC module has been driven, it is low -voltage electricity, so the safety performance is relatively strong. However, after the driver is added, the cost will increase the cost. , The lamp body will change.

UV LED light source, which is the abbreviation of ultraviolet light emitting diode. From the perspective of human health and environmental impact, we can divide the purple light according to the wavelength of the wavelength: UV (purple light): visible light purple light (400-420nm) ) UVA (315 400nm), also known as long wave purple light or "black light". .. UV LED light sources, that is, the abbreviation of ultraviolet light emitting diode. From the perspective of human health and environmental impact, we can divide the purple light according to the wavelength. 400-420nm) UVA (315 400nm), also known as long wave purple or "black light". UVB (280 315nm), also known as Middle waves purple light. UVC (200 280nm), also known as short -wave purple light or sterilization purple light. UVD: Vacuum UV (100-200nm) Sunlight contains UVA, UVB, and UVC's ultraviolet light in three bands, but due to the absorption of ozone layers in the air, 99%of the UV light on the ground is in the UVA band in the UVA band. UV LED generally refers to LEDs below 400nm in the center of light, but sometimes it is called near ultraviolet LED when the glowing wave is greater than 380nm, and when it is shorter than 300nm. UV LED (UV LED) is mainly used in the fields of biomedical, anti -counterfeiting identification, purification (water, air, etc.), computer data storage and military. And with the development of technology, new applications will continue to appear to replace the original technology and products. UV LEDs have a broad market application prospect. For example, UV LED phototherapy instruments are very popular medical devices in the future, but the current technology is still in the current in the future. Growth period. UV LED is receiving widespread attention from lighting equipment manufacturers and LCD display manufacturers. Because by using ultraviolet light and converting ultraviolet light into red, green, and blue fluorescent materials, it is possible to achieve a white LED with strong color reproduction. At present, most of the commercially available white LEDs use blue LEDs and fluorescent material materials that convert blue light into yellow light. The red light components are weak. When it is illuminating the white light on the red material, it will show a weak orange. If you want to use it for a backlight, you have to find a way on the color filter. But if it is ultraviolet LED, you can solve these problems. However, because the light -emitting efficiency of ultraviolet LED is about half lower than that of blue LED products, the brightness has become a major topic of ultraviolet LED.
