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.

The rise of the domestic LED lighting market first starts from the field of LED light source module brand. From the "Ten Ten Citys" to "Millions of Fifty Cities", LED outdoor lighting has been encouraged and developed rapidly by policies. In order to better conform to market development, LED companies have strengthened the research and development of technology. From a single imitation to the current LED street lamp module of the Lighting Engine, the rapid progress of technological progress has greatly promoted the development of LED street lights. The so -called modularization refers to the composite production modules such as light sources, heat dissipation components, and driving power supplies for mass production, and manufacture standardized LED lighting products in accordance with fixed parameters and molds. At present, there are not a few companies that make LED light source modules. In the light source module solution with self -heat dissipation, most of them are directly exposed to the sunshine of the lens made by high molecular materials. At the same time, the module -connected wires are also directly exposed to the sun. UV rays will have a significant impact on the performance of these materials on these materials. A standardized good light engine can solve the problems of many high -power LED lighting fields such as heat dissipation, waterproof, series of waterproof, serialization, maintenance, and universality. After the reliability is guaranteed, it should be more concerned about the uniqueness of the module on the LED street lights and the superior performance of the traditional street light lighting. There are not many street lights now. I believe few people will impress the street lights on a certain road, because it looks almost the same. As the "high -precision" of electronic products, LEDs are completely different, so that each road has the characteristics of each road, so that people can make people shine. In fact, from the design of the LED light source module brand, whether it is the modularization of the light source or the modularity of the light engine, it provides a broad design space for the design. In the future, according to the different application requirements, you can choose different modules to choose different modules in different modules in the future. Design. From this point of view, LED street light companies, including outdoor high -power module manufacturers, still have articles to do. Can't get out of the market to talk about products, nor can it be discussed to talk about the market. Now that we are in the era of LED lighting, what we have to do is to study how to play the advantages of LED light source module brands, and better serve the people's living life.

Since the early 1900s, ultraviolet (UV) light has been used to cure skin disorders. It is common knowledge that sunshine has therapeutic benefits but can also have negative consequences, including burning and cancer. A wide range of dermatologic disorders can now be treated with the creation of artificial UV sources, which are more precise, safe, and effective thanks to extensive research that has improved our comprehension of Uv rays and their consequences in human systems.

What Functions Does UV Light Serve?

Let's look at several of the most common uses for ultraviolet light, which are numerous and frequently essential in medical situations.

UV light can be used for several purposes, including hardening dental fillings and spotting fake currency. Here are just a few helpful applications for UV light!

· Air Disinfection

UV light can be utilized in any foundation to sanitize air spaces. This type of sterilization is more powerful on still or stale air than on moving air since there should be sufficient contact between the air and the UV light. Numerous offices choose to add UV sanitization lights at the high room level to build the adequacy of air sterilization.

This will make the air cleaner as it normally circles. Also, offices might choose to put UV lights close to the loops and channel dish of cooling frameworks, including forced air systems and refrigeration units, to prevent microbes from creating in those soggy, cold conditions and, at last, scattering high up.

· Offices for Water Sterilization and Wastewater Treatment

These can likewise utilize UV light for wastewater treatment as well as water sanitization. UV sanitization can be an extremely protected and proficient option since an actual cycle doesn't need the expansion of synthetic compounds to the water to clean it.

Parasites like cryptosporidia and giardia, which might endure even substance therapy, can be more uncommon thanks to UV radiation. Multiple billion gallons of water each day are treated at one New York plant utilizing UV light before being utilized in New York City.

Regardless of whether wastewater treatment should be finished on a lot bigger scope, UV light can, in any case, be vital to the technique and even supplant chlorination.

While by all accounts not the only technique for sterilization, the utilization of UV radiation in numerous metropolitan regions as a feature of the wastewater therapy process has become rather broad.

· Surface disinfection

It ought not to be unexpected that surfaces in medical care offices and different settings can profit from being sanitized utilizing UV light. Truly, UV light can rapidly kill microorganisms on a surface, including live infections. In this circumstance, UV can be more powerful and proficient than other cleaning and sanitizing methods in medical care organizations.

· Gear Cleaning

UV light is a popular sterilization strategy for hardware, notwithstanding fixed surfaces like counters, tables, and floors. For example, research facilities that risk tainting could utilize UV to clean lab hardware like goggles and dishes. The UV light enjoys the benefit of being proficient yet, in addition, dry and direct, as opposed to scouring or cleaning, which can abandon soil and moistness.

· Drink and Food Sterilization

UV radiation is utilized in food and drink sterilization since it is similarly viable on surfaces and fluids. When used to sanitize objects like transport lines that are generally difficult to clean really, UV sterilization has been exhibited to find actual success in food-producing plants. These surfaces can be cleaned without decreasing the gear's life expectancy, gave the right materials are utilized. It's vital to contemplate the sort of UV light being used while concluding which applications UV light can be utilized to sanitize.

Far UV and close UV can influence microscopic organisms and infections in unmistakable ways. Download this archive to study further how far UVC is utilized to sanitize surfaces.

· Antibacterial Lamps

UVC light applications are frequently used in many sectors to disinfect surfaces, water, or both. The food sector uses UV lamps to disinfect surfaces when exposed to radiation. The irradiation method is used to extend food's shelf life, maintain its nutritional content, and sterilize germs in food to lower health risks.

· Water Treatment

A secure and effective method of treating water is with UV lights. As a result, there is no need to use dangerous chemicals that could harm oceans and rivers. Medicinal air conditioning systems also use germicidal lasers to kill disease-causing bacteria.

Our bodies need the vitamin D that is stimulated by UVB sunbathing, and too much of it can cause tanning. Sun beds use UV lamps to help people tan, but too much UV exposure can lead to various skin malignancies.

· Sterilization

UV has the power to render viruses and germs inactive. UVC is used to disinfect medical equipment as well as surfaces.

· Cosmology

UV radiation is produced in some actions by extremely hot items. More UV is discharged when an item is smoking more. We can more deeply study heavenly items' temperatures and synthetic cosmetics by seeing and recording the UV radiated by stars, planets in our planetary group, nebulae, and universes. The main issue is that because the ozone layer on our planet retains such a lot of UV light, these examinations should be finished beyond the environment.

· Curing

After it was first found in the mid-nineteenth 100 years, relieving UV radiation was once alluded to as "substance beams." This was because of the synthetic changes that UV could set off in certain mixtures. Various utilization of this impact incorporates the fast solidifying of particular pastes. It is known as "relieving" to do this.
