Many LED lighting masters, they pay great attention to LED lamp bead lighting computing. In their LED lamp bead lighting schemes, there will be a considerable part of the simulation calculation of LED lighting design. Moreover, the more complicated the space, the more you need to perform lighting calculations. As a quantitative design method, the illumination calculation is indispensable on most occasions. If there are some errors, it is not difficult to find the necessary illuminance through the LED lamp bead lighting design. Today we will introduce two methods. 1. The LED optical flux method LED lamp beads The optical flux method is mainly used in the equivalence of the LED lighting lamp space, and the calculation average illuminance is used. In addition to the use of open space such as office and factories, in restaurants, restaurants, houses, etc. need to improve In the space of the atmosphere, in order to confirm the approximate degree, it is convenient to use this LED illuminance calculation method. 2. The LED one -point calculation of the calculation of the calculation of the calculation algorithm is used when calculating the actual degree required for local lighting and the key display section. When the LED lamp beads are calculated for the calculation of the light flux method of LED lamp beads, 1 When installing a 100W nude bulb of 500lm, it is assumed that 30 % of the light beam should be directly illuminated on the ground. So how much is the direct illumination on the ground? E = f / a = 1500 * 0.3 / 10 = 45LX Except for the beams that are illuminated on the ground, other beams illuminate the ceiling and wall surface. If the reflectance of the ceiling and the wall is high, the reflection light will be added to the direct illumination of the ground, so the actual illumination is above 45LX or more. Most of the lamps for the basic LED lighting are direct light -equipped down light lighting and mixed lighting lamps of fluorescence lamps, as well as indirect lighting of ceiling tanks such as light glow slots. The illumination calculation of direct light matching, the more the light is affected by the ceiling and wall reflectance. Even if the setting of the room's reflectance is somewhat different, the average illuminance error will be. However, if there are high partition walls and furniture, the calculation results of the shadow part of the shadow deviate from. In addition, the indirect LED lighting of the ceiling must not only be affected by the ceiling surface, but also greatly affected the wall reflectance rate. The distance from the ceiling is different, and the lighting utilization rate will change, so it is difficult to calculate without error. Example: A room with 8m front room, 10m depth, and a net height of 2.4m. In order to make the indoor lighting uniform, 20 pookers lighting A light folds are neatly arranged, and the average on the ground is calculated at this time Photo? (The reflectance of the room is the ceiling: 70 %, the wall: 50 %, the ground: 20 %), the room space index = the opening room * depth / (opening room in -depth) * The height of the light source = 10 * 8 / (10 8) 2. 4 = 1.85, if the room spatial index is roughly taken between 1.5 and 2.0, where the reflectance of the room intersects, the lighting utilization rate is about 0.6. Maintenance rate M, incandescent lamps are 0.7 to 0.9, fluorescent lamps are 0.65 to 0.75, here is 0.8. E = f * n * u * m / a = 1520 * 20 * 0.6 * 0.8 = 180lx Average multiplied by the light of the lamps within the value of H (high light source), which means on the ground or work surface Will not produce uneven light spots. Calculate the illumination of a specific point. Since the local lighting of hanging decoration and lighting lights is used, when calculating the direct horizontal plane strength or vertical surface illumination of a specific point, the illumination can be used to use the point -by -point calculation algorithm one by one.

New technologies and new solutions in the application have also emerged. LED lighting design can combine the characteristics of light sources, such as light sources, cold light sources, and color changes, etc., will definitely become the mainstream of the lighting market. In recent years, with the continuous improvement of LED's research on material selection and packaging architecture design technology, a new AC Light -emitting diode AC -free LED technology came into being. Through a new idea, it promoted LED lighting technology Practical. AC -free LED is relative to the traditional DCLED. It does not need to pass AC/DC conversion, which can be directly plugged in LED lighting technology used in 220V (or 110V). The key to AC -free LED technology is the special arrangement and combination of LED grains in packaging. At the same time, the diode characteristics of the LEDPN knot are also rectified. Through the semiconductor production process Crystal technology, and adopt the staggered matrix arrangement process to form a bridge circuit, so that the AC current can be turned on in two -way, and the light emitting. The arrangement of grains is an AC driver -free LED grain grains using a staggered matrix arrangement schematic diagram. Actually AC -free LED grain arrangement photo, AC -free LED grain grains to glow after connecting the communication, so only two leading leads need Import and communication source can glowing work. The working principle of the AC -free LED light source is composed of a staggered matrix arrangement process by the LED microlymation. The grains, the positive half -along the real line of the communication, the LED grains of the 3 bridge arm are glowing, the negative half -along the dotted line, and the LED grains with 3 bridge arms are glowing. Glowing, relative to the LED grains on the bridge arm at the same time, and the LED grains on the middle bridge arm have been glowing due to the sharing. AC -free LED is small and is generally used for industrial and civilian small indicators; high -voltage and low -current in -depth advantages overcomes the problem of high loss of the line when using DCLED, which depends on the continuation of the power supply of the power supply; Light LED non -electrostatic breakdown ESD problem; use micro -grain technology to greatly improve the lighting efficiency; due to the improvement of power factor and low current control, for the general lighting industry and the LCD backlight panel industry, it is also a new technologies. At present, the AC -free LED is still being continuously updated in terms of glowing brightness, power, etc., but the access of AC -free LEDs is simple and low -cost, high -efficiency. AC -free LED's technical certificate is developing. It is believed that in the near future, high brightness, high -power, and low -cost products will be available in large numbers.

The LED integrated light source is different from the COB light source: 1. Different LED chips used for LED chips generally use large size high -power LED chips with a large size of more than 1 watt. The COB light source is mainly based on a small -power LED chip of less than 1 watt, and a small amount of COB light source will also use a high -power LED chip of more than 1 watt. 2. Different supports used by LEDs are only 10W, 100W, 500W and other square brackets. The materials are mainly copper, and the brackets have 2 side feet. There are many sizes used in the COB light source. Its shapes are square, rectangular, oval and other dozens of stents. The materials are mainly aluminum, and there are copper and ceramic brackets. Generally, they are generally all. Not to bring. 3. Different LED integrated light sources in the use of light sources is to make outdoor lamps such as LED light lamps, LED street lights, etc., and its maximum datches can reach 500W. The COB light source is mainly used on the indoor lamps such as LED downlights, rail lights, ceiling lights and other indoor lamps. Extended information: COB integrated light sources are widely used for LED ball bubbles, LED light cups, LED spotlights, LED downlights, LED ceiling lamps, LED bean bile lamp products. They are one of the mainstream trends of LED lighting light sources. LED lights are light -emitting diode. They use solid semiconductor chips as luminous materials. Compared with traditional lamps, LED lights are energy -saving, environmentally friendly, color rendering and response speed. 1. Energy -saving is the most prominent feature of LED lights. In terms of energy consumption, the energy consumption of LED lights is one -tenth of incandescent lamps, and a quarter of energy -saving lamps. This is one of the biggest features of LED lights. People now advocate energy conservation and environmental protection. It is precisely because of the characteristics of energy saving that the application range of LED lights is very wide, which makes the LED lights very popular. 2. If you can work on the high -speed switch status, we usually walk on the road, and you will find that the screen or screen of each LED is unpredictable. This shows that LED lights can be done at high speed switches. However, for the incandescent lamps we usually use. When living in normal times, if the number of switches is too large, it will directly lead to the broken incandescent lamp. This is also an important reason for the popular LED lamp. 3. Environmental protection LED light does not contain any heavy metal materials such as mercury, but incandescent lamps are contained, which reflects the characteristics of LED light environmental protection. People now attach great importance to environmental protection, so more people are willing to choose environmentally friendly LED lights.

There are many advantages such as light source, driver simplified, beam concentration, fast care speed, etc. There are many advantages. LED dot light sources have been widely used in phenomenal lighting. This is a well -known actual practice. The rapid development is gradually replacing high -pressure sodium lamps and metal halide lamps that have been dominated in journey lighting. We are no stranger to the red light laser module. We can still be seen in our days, especially if you use it on the stage, you will have more. View the plug of the laser signal line, the need to disassemble the interface, view Is the connection between the core and the wire of the wires strong?. The quality and function of the red light laser module directly affect the operating power of the CO2 laser marking machine. This is also one of the primary part of the CO2 laser marking machine. Usually CO2 laser marker laser is often made of hard glass, usually a layer sleeve structure. The first layer of the inside is a discharge tube, the second floor is a water -cooled sleeve, and the first layer of the outer layer is the gas storage pipe. Carbon dioxide laser discharge tube diameter is thicker than HE-Ne red light laser module. The thickness of the discharge tube usually has no effect on the output power. The first consider the diffraction effect caused by the fineness of the light spots. The red light laser module has high brightness and high energy density. It is the source of brightness in the contemporary world. A L milliles of ammonia is a hundred times brighter than the sun, the Zhuhai LED extension tablets, and the greater ruby red light laser module is more than the sun. When this light can cause thermal energy, it can develop a low temperature from thousands of to tens of thousands of degrees. The spectral spectrum of red light laser modules is very narrow, and the general spectrum is one million times wider than hundreds of millions of times. The red light laser module is a beam -like parallel light. It only shot a bias and the range is far away. It can form a very slender light spot through the lens collection. The frequency, firm bias and firm measures of red light laser module light waves have a good correlation. The high brightness, monochrome, biasedness and correlation of the red light laser module make the energy of the red light laser module highly concentrated on the hour, space, and spectrum. These characteristics of the red light laser module enable it to show their magical powers in many areas, including medicine. When the red light laser module is influenced by the biological body, it is received and transformed into a thermal energy. Laser module consists of laser tube and laser head modules. Usage: For laser i gun, laser rake, instrument, LED extension, wholesale, flashlight, etc. Advantages: In terms of application, the module has higher machine strength, easy to device, resist trouble, and it is not easy to damage.
