Mine lighting LED lamp beads light sources are an important part of the mining machinery industry. Old -style mine lamps such as incandescent lamps, fluorescent lamps and high -pressure sodium lamps, which not only consume large power, but also have a short light bulb life, small luminous area, and uneven light. Especially the old -fashioned mine lamps are mostly used in improper use and can cause the ore gas explosion, which seriously endangers the safety of mines. A 4th generation new -type light source light -emitting diode (Lighting Diode) LED lamp beads with high energy saving, environmental protection, harmless, long life, low heat, earthquake resistance, and high color purity. Lights, traffic lights, car lights, etc., there will also be a wide range of application prospects in the lighting of the mine. At present, mining lighting is mainly divided into factory ground lighting and mining underground lighting. Factory ground lighting is the same as the light source in daily life. Litto lighting can be divided into lane lane lighting, work -faced lighting, and other work point lighting, etc. The selection of LED lamp beads should be selected according to different environments and use requirements. Alleyway lighting mine lane lane lighting is mainly to provide lighting for transportation or pedestrian channels. At present, most of the lane lane explosion -proof lamps widely used at home and abroad use ordinary straight fluorescent lamps as light sources. It has shortcomings such as electric energy consumption, short light bulb life, and difficulty in maintenance. The light source of LED lamp beads can not only consume low and save energy, but also has a long life, which can effectively reduce the maintenance of the lamp lamps. Now my country's mine has begun to promote the lane lane explosion -proof lamps of LED lamp beads. Although there are still certain problems in the initial stage, as the improvement of LED light source technology, its application in lane lane lighting will become more and more wider and wider and wider. The workmarking of the job is now the light source used in mining work, which is often used in small dual -tube core high -pressure sodium lamps. Although its life span is long, its light color is not very good, which makes the entire work surface dim, and it is easy to cause accidents to occur in the occurrence of accidents. In recent years, with the rapid development of lighting sources, it is gradually applying to mining working surface lighting. Different from conventional high -voltage sodium lighting sources, it uses low -voltage DC power supply. High -efficiency white light diode synthesized by GAN base power type and yellow fluorescent powder has the unique advantages of high -efficiency, safety, energy saving, environmental protection, long life, fast response and high unique advantages. With the technological progress of the LED light source, the light power LED light source will be widely used in the work -facing head surface. The old -fashioned lamps in the mine lamp are mostly incandescent lamps. The electric energy consumption is large and the luminous lights are short. The LED light source lighting technology is used on the lamp, and the advantages are obvious. It has the same advantage of the old -fashioned mine lamp and 1/3 of the incandescent lamp consumption. Therefore, the LED mining light is now widely promoted and gradually replaced by the old -fashioned mineral lamps. In addition, because the LED light source has earthquake resistance and impact resistance, the explosion -proof LED light source lamps are also applied on locomotives such as excavations and achieved good results. With the continuous improvement of LED light source technology, its application prospects in mine lighting will be more extensive. The method of improving the output power of LED light sources is the most important parameter of the lighting source. The luminous efficiency of LED is the ratio of the electrical energy of transmission and input. To improve the lighting efficiency of LEDs, it can improve the transmitted light flux, that is, the LED output power. For a single LED, the output power is very small, often adopted or circularly arranged to obtain a large power output, which causes the disadvantages of excessive volume and difficulty in heat dissipation. To obtain the optimized distribution scheme between the output power and the number of LEDs, the following measures can be taken. 1. Improving the heat dissipation efficiency. The LED light source is a cold source. The single LED heat is very small, but for the LED dot matrix, due to the large number of LEDs, the arrangement is dense, and the heat is not ignored. If there is no good heat dissipation control, the LED will not work properly. The output power will be greatly reduced. Methods to improve heat dissipation efficiency are high -thermal guidance materials, increased heat dissipation area, and improved heat dissipation methods, etc. 2. Increased reflective (umbrella) cover LED and strong direction, but the scattered angle is large, such as glowing LED, horizontal vertical scattered angle°. Adopt the method of increasing the reflective (umbrella) cover, collect as much as possible as much as possible, the rear direction and edge of the LED, reduce the loss of light, and use the output power to maximize the use. 3. The LED arrays of the LED array of LeD standard system is a divergent light source. In order to reduce the loss of light, in addition to increasing the reflex (umbrella) cover, a new lighting system LED diagnostic optical system can be used. As shown in the figure, it is shown in the figure. The LED array quasi -direct optical system This system adopts non -imaging optical method to effectively converge the optical flux of the LED array, convert the optical flux into a high brightness convergence of the light beam, so as to obtain a small divergence area and increase the LED output power. In recent years, my country's LED lamp beads have rapidly entered the mainstream lighting system, and they are gradually applied in the mine. Although there are still some technical problems in the popularization of mines, such as the optical flux needs to be improved, there is still a certain gap between the light from the LED lamp beads and the natural light;. However, LED lamp bead light sources will be mature, and some technical difficulties will gradually solve, especially in the context of global energy shortage, the market prospects of combining LED light sources and solar energy are very huge. The application prospects of LED light sources in the lighting market will be massive, and it will definitely become the dominant light source of the 21st century and contribute to the mining lighting.

What are the four parameters of the LED module light source lamp? Let s introduce the four major parameters: the LED module light source light tape parameters are color: this is a basic parameter, different colors are applied in different occasions. According to the color type, it can be divided into three types: monochrome, colorful, and full -color single -point control. Monochrome is a single color and cannot be changed. You can work after connecting the power supply. Colorful is that the entire string of modules can only be the same color, and cannot achieve different colors of a single module. In simple terms, only all modules can only achieve the same color at the same time. Inter -changing. A single point of full color can be controlled to the color of each module. When the number of modules reaches a degree, the effect of displaying pictures and videos can be achieved. You need to add control systems to achieve the effect of colorful and full -color single points. We will introduce the control system selection and application in detail in the control system chapter. LED module light source lamp band parameters are voltage: this is a very important parameter, the current 12V low -voltage module is more common. When connecting the power supply and the control system, you must check the correctness of the voltage value in order to power the power, otherwise it will damage the LED module. LED module light source light band parameters III is working temperature: that is to say, the temperature of the normal work of LED. Usually between -20 60 , special treatment must be performed if the required range is relatively high. The LED module light source lamp band parameters Fourth is the lighting angle: the LED module that does not have a lens is mainly determined by the LED. The different light angle of LED is also different. Generally angle.

The changing range of LED lamp bead VF is not considered, resulting in low efficiency of the lamp, and even the price load of the LED light source module in unstable LED light source module. It is generally composed of several LED string of LEDs. quantity. LED's VF changes with temperature changes. Generally, at the constant current, VF becomes lower at high temperature, and VF becomes high at low temperature. Therefore, the working voltage of the LED lamps load at high temperature corresponds to VOL, and the LED lamp load load operating voltage at low temperature corresponds to VOH. When choosing the LED drive, the driver's output voltage range is greater than VOL VOH. If the price of the LED light source module to the large output voltage is lower than VOH, the tolerance of the lamp at low temperature may not reach the actual power. If the selected LED drive to the low voltage is higher than VOL, the drive may be driven at high temperature at high temperature. The output exceeds the scope of the working, the work is unstable, the lamps will flash, etc. But comprehensive cost and efficiency consideration, you cannot blindly pursue the range of the LED driver's ultra -wide output voltage range: because the driver voltage is only in a certain range, the drive efficiency is the highest efficiency. After exceeding the range, efficiency and power factor (PF) will deteriorate. At the same time, the design of the output voltage range of the driver is too wide, which will lead to increased costs and efficiency cannot be optimized. If the power balance and reduction requirements are not considered, the nominal power of the LED drive refers to the data measured by the rated environment and the rated voltage. Considering that different customers will have different applications, most LED drive suppliers will provide a power reduction curve on their own product specifications (common load VS ambient temperature drop curve and load VS input voltage reduction curve)). The red curve indicates that when the price of the LED light source module is input 120VAC, the power reduction curve with the ambient temperature changes. When the ambient temperature is lower than 50 C, the driver allows 100 full loads. When the ambient temperature is as high as 70 C, the driver can only reduce the load to 60%. When the ambient temperature changes between 50-70 C, the drive load of the drive is with the temperature with the temperature with the temperature Rise and linear decline. The blue curve indicates that when the LED driver enters 230VAC or 277VAC, its load has a power reduction curve with the changes in the ambient temperature. The blue curve means that when the LED driver is 55 C, the output power reduction curve with the changes in the input voltage changes. When the input voltage is 140VAC, the load of the driver allows 100 full loads, and as the input voltage is reduced; if the output power remains unchanged, the input current will rise, resulting in the increase in input end loss, the efficiency decreases, the temperature of the device will rise, the individual temperature points may be possible. Excessive standards may even cause devices to fail. Therefore, when the input voltage is less than 140VAC, the output load of the driver is required to be reduced with the input voltage and the linear decrease. After understanding the upper reduction curve and the corresponding requirements, when choosing the price of the LED light source module, you should comprehensively consider and choose according to the actual environmental temperature and input voltage conditions, and leave appropriately to leave the reduction of the reduction of the reduction of the reduction amount.

With the increasing number of LED -integrated light source modules, how can we choose the right LED module? What kind of manufacturer is the right manufacturer? The editor believes that there are three main factors, namely: quality, price, and supply period. Quality, this is a very important discrimination factor in choosing the LED module product. If the quality of a manufacturer's LED module is unqualified and the effect does not meet the actual requirements of the project, then the low price, the project purchaser will not choose such LED module manufacturers as their own partners. The quality of the LED integrated light source module is hard requirements. If the corresponding requirements are not met, it will be eliminated. This requires that the LED module manufacturer should pay attention to the quality of their products. As a brand LED power manufacturer, Tianhui Optoelectronics has strictly inspected every product produced to ensure that each product meets 100 % of the testing standards. Mass 100 % guarantee for customers! Price, price is not only important for LED module manufacturers, but also very important for the purchaser. Although the current LED module market, the price competition is relatively frequent, but the overall cost is still there. As a purchaser, of course, the lower the price, the better, but in terms of the processing process of the LED module, this will be Impossible. Therefore, the price of LED modules is too high or too low is doubtful. Here, although Tianhui Optoelectronics cannot promise to give you a low price, we can guarantee that you are very satisfied with the products and services! Supply period, this is also a very important factor. The supply period is an aspect of worrying that the purchaser is more worried, because the LED module is used in LED lighting, the smooth supply of power supply seriously affects whether it can be smoothly illuminated! Tianhui Optoelectronics here solemnly promises to ensure that the supply is sent to the customer on time on time. The quality, price, and supply period are not allowed. These factors comprehensively test the true production strength of an LED integrated light source module manufacturer.
