Rayven cob 240v led downlight for business for restaurants

LED spotlights can be said to be very popular nowadays. Whether as an artistic light source or as a direct lighting fixture, LED spotlights have an irreplaceable and increasingly important position. Many people don't know how to choose LED spotlights when they buy LED spotlights. Below, Rayven led spotlights manufacturers will answer for you how to choose LED spotlights.Whether it is home lighting or commercial lighting, we roughly divide the lighting design into two types: design with main light and design without main light. The main lamp design refers to the lighting combination of main lamp (chandelier, ceiling lamp and other relatively large lamps) + auxiliary lamp (table lamp, floor lamp, wall lamp, downlight and other small lamps), but without main lamp design, It mainly uses spotlights, downlights, light strips, and auxiliary lights to design the lighting of the entire space.Among them, LED spotlights are designed without a main light, or even an indispensable illuminator in a design with a main light.Tips for choosing LED spotlights1. LED spotlight drivingAs the core component of LED spotlights, the brand and quality of the driver often determine its lighting effect and service life. When we choose LED spotlights, we might as well read the manual carefully, or consult the store to learn about the brand and grade of the driver.2. LED spotlight chipThe importance of the LED spotlight chip is that it directly affects its brightness, life, light decay, etc., and has the same importance as the driver. To be honest, in the lamp chip, we still think that the domestic big brands are more reliable than the imported ones. Some unknown small road products are not recommended.3. The appearance of LED spotlightsIt's like we said: Buying clothes to look at pockets, buying shoes to look at shoelaces is the same. High-quality LED spotlights should be good from the inside out. For example, we touch it with our bare hands to see if it has a smooth appearance, with obvious scratches and burrs from cutting hands. Shake it slightly to hear if there is any abnormal noise inside. As long as there is abnormal noise, don't buy it. 4. The body of the LED spotlightCommon LED spotlights are made of metal, PVC, ceramic, etc. From the perspective of heat dissipation, we usually recommend choosing metal and ceramic, but the cost of both is relatively high.5. Type of light source of LED spotlightThe light source of LED spotlights is generally LED. Common light sources include energy-saving COB, chip wafer, halogen lamp, and metal halide lamp. The first two are LEDs, and the latter are mostly used in industrial and mining places and are not suitable for home use. . The most popular commercial and household LED spotlights nowadays are COB LED spotlights. Among them, halogen lamps have been gradually eliminated by the market due to poor light efficiency.6. LED spotlights should pay attention to glareGlare (what is glare and how to avoid glare?) is something that we must avoid when lighting any scene and choosing any lamps. We can often see the existence of LED spotlights in some commercial stores (without reasonable design), but often due to unreasonable selection and installation, the glare is widespread, which gives people a very bad feeling. At home, this situation is even more harmful to the body.7. The brand of LED spotlightsI mentioned the reference factors for choosing LED spotlights, but in fact, many people will not settle down to study and learn. Then, we think that a more convenient way to judge is to choose LED spotlights from regular led spotlights manufacturers and well-known brands. Relatively speaking, the probability of making mistakes in such brand products is much smaller, and negative news has a greater impact on LED spotlight manufacturers. Therefore, they are more motivated to ensure product quality.Moreover, for high-quality LED spotlights, common parameters such as color temperature, color rendering index, luminous angle, beam angle, and luminous flux will be clearly marked on the outer packaging. However, small factories and inferior products have relatively few manifestations in this regard, and these parameters are not even marked.Application of LED spotlights in home lighting designAs a decorative light and auxiliary light, the role of LED spotlights in home lighting cannot be underestimated. It can add a lot of color to the room. If it is a modular home, choose one or several LED spotlights to install on both walls of the furniture, the lamp frame is vertical, and the lamp shade can be slightly inclined. If the LED spotlights are directly installed in the partition area of the modular furniture, it can be used for local lighting, but also can enhance the atmosphere, playing a "finishing finishing touch" role.In bedroom lighting design, LED spotlights will also be frequently used. For example, it can be used as a bedside lamp when installed on the bedside, which is stylish and elegant with soft light. The height is generally parallel to the head when sitting on the bed. The lampshade used is completely opaque, and the light is concentrated on the illuminated surface, so when it is turned on at night, it will not affect others' rest.LED spotlights can also be used as mirror lights in the bathroom. The installation location is above the washbasin. The lampshade can rotate freely, so a lamp can meet the lighting requirements. Wherever lighting is needed, turn the lampshade to that position. Now many people will try to use LED spotlights instead of heavy chandeliers to make the whole space look brighter. When the room is long or has a wine cabinet, etc., you can install a row of LED spotlights; if the space is square, you can install LED spotlights around the ceiling for independent control, which can become the main lighting of the room, but also It can be used as an independent atmosphere lamp to create a warm life.In addition, LED spotlights can also be placed in walls, skirts or skirtings as hidden lighting. Only need to light the furniture and utensils with accent lighting to highlight the texture of the material and achieve the artistic effect of highlighting the key points and setting off the atmosphere.LED spotlights are soft, easy to change, simple and fashionable. They are the best choice for modern home decoration lamps. Compared with other lamps, they have relative advantages. You can change and use LED spotlights according to the whole home style, which will not make us feel fatigued, and it will always make people shine. The whole home space is full of modern fashion and artistic sense.LED spotlights are more than just selecting lights, it is a work that is both technical and artistic.

Downlight fixtures body adopts metal material as a whole molding process and the combination of flame retardant PC material. The metal material department is processed by polishing, oxidation and baking paint to make the appearance smooth and textured. Improve downlight fixtures product quality. Intelligent IC drive, cross current constant voltage, overload protection, undervoltage protection, short circuit protection, using the built-in drive scheme, the shell is made of flame retardant PC material.Let's see how the downlight fixtures are installed. Method of installing downlight fixtures Taiwan crystal/SAN - an lamp is adopted, and COB lamp beads with high light efficiency and high finger display are adopted. The reflectance of the reflective cup is up to 95%+, and the transmittance of the v-shaped light conducting lens is up to 95%+ with imported PC material. The precision injection molding ensures that the light spot is more round and the light is more uniform. Downlight fixtures brand LED downlight fixtures brand: LED downlight fixtures installation procedures include the track, the lamp holder installed in the track, the lamp holder fixed on the lamp holder, the lamp installed in the lamp holder. Two conductive plates are arranged at the top of the track and a long strip of groove groove is arranged at the bottom of the track. Installation preparation: for important safety issues, remember to turn off the main power supply to ensure safe operation after the power supply has been turned off. Next, check the wiring and track, and confirm that the track has been installed at the installation lamps. If not, install the track there first. Since the track needs to bear the weight of the installed lamps for a long time, the strength and tightness of the track should be paid attention to during the installation to ensure the reliability. After the track is installed, install the conductive head near the wiring place at the end of the track. Be careful to tighten the screws. Can begin to install shoot light next, embed lamp holder directly inside orbit, make this lamp holder can be moved laterally in order to adjust lamplight to project a position, compare traditional photograph to have the advantage of small volume, consumption of electricity is little, luminous efficiency is high, can adjust conveniently and move position. Installation precautions: load the spotlights into the proper place of the track. Note that the track matches the connector of the led downlight. There should be certain directionality when the track and connector are assembled: after installing the spotlights, adjust the horizontal and vertical angles of the lamps according to the position of the projected objects, so as to ensure that the spotlights can project the illuminated objects fully and effectively. The installation method looks quite complicated, but actually it is quite simple to do. Factors affecting the service life of LED downlight fixtures panel lamp One, the use of the lamp bead, we all know that the chip of the lamp bead is to have copper wire and iron wire more, copper wire is better than iron wire chip, the service life is also much longer than iron wire chip, all we choose the lamp why the same lamp has two kinds of unit price is this reason. Second, the power factor of the power supply, this factor is very important, if the power factor of the power supply is very low, the power saving is very poor, a good power supply can not only have good power saving ability, can play the protection measures of the lamp, when the voltage is unstable, it can be very good to prevent the damage of the lamp of the unstable current. 3. Heat dissipation effect. If the heat dissipation design of a lamp is not good, it will also affect the service life of led downlight fixtures panel lamp. Ballast is the heart of led panel lamp, it is directly related to the lamp life. At present, a good led panel lamp generally USES IC drive cross-flow power supply, with short circuit, short circuit, overload and other protection functions, very safe and stable, can guarantee the lamp's life. The ballast of some lamps USES the solid waterproof irrigation glue, have very good waterproof, heat dissipation effect, but do not have the protection function of former one kind. And inferior led panel lamp USES inferior irrigation glue, some even the tar that infuse, cannot guarantee the life of the lamp at all. When selecting, must pay attention to the ballast quality.

Ultraviolet sterilization lamp is commonly used in the place that is easy bacterium to breed, wait for dim and moist place such as kitchen, toilet, also can be used in the space that requests taller to the environment quality, wait for medical treatment place such as ward, operating room. Nowadays ultraviolet sterilization lamp also applies commonly in a few electric appliance product inside, for example air purifier, new fan, clothings is taken care of the indoor purify installation and clothings to take care of disinfection installation, everybody knows ultraviolet sterilization lamp is to be able to kill a few bacterium, but know how to do the disinfection job of ultraviolet sterilization lamp not necessarily?The disinfection of ultraviolet sterilization lamp main pointsBecause what we use to air disinfection is ultraviolet light, because this must ensure lamp tube above all intact and correct use, want to stop monitoring to lamp tube regularly again at the same time, the intensity of lamp tube of ultraviolet ray is lower than 70uwc/ line should change in time. Should insist that the lamp tube is clean. Lamp appearance every 1~2 weeks with alcohol cotton ball light test, remove dust and oil, in order to reduce the influence of ultraviolet penetration.Lamp tube should be taken gently gently put, after turning off the light, turn on the light immediately, can reduce lamp tube life, should be cooled 3 1 4 minutes to open again, can use continuously 4 hours, but ventilated come loose heat is good, with insisting lamp tube life. The cleanness that should insist cure room at any time is dry, the special duster cloth after soaking with antiseptic fluid wipes cure room everyday. Mop the floor with a special mop.Standard ultraviolet lamp daily monitoring cancellation items, it is necessary to achieve the room, the light stop cancellation, cancellation of the lamp set in the opening date, daily disinfection time, cumulative time, signature of the performer, intensity monitoring cancellation, request disinfection after careful record, so that the implementation and record adhere to differences. For the newly used lamp tube, the ultraviolet intensity indicator card or intensity monitor shall be used to measure the intensity of the lamp tube to ensure that the intensity of the new lamp tube is above the 100. W /c line.After changing the new lamp tube, the mould using time began to time again, the cumulative use time of the lamp tube reached 1000h, timely contact with the hospital infection monitoring staff to stop the light intensity monitoring, if qualified continue to use, unqualified timely change the lamp tube, in order to ensure the ultraviolet lamp to obtain disinfection effect. When air disinfects, open all cupboard door drawer to wait. In order to ensure the sufficient exposure of all Spaces in the treatment room, get the reflection of ultraviolet ray, disinfection as far as possible no dead Angle.Precautions for using ultraviolet sterilization lampWhat demand prompts is, ultraviolet lamp tube has certain life, when using, want to notice to change lamp tube in time. According to the requirements of GB/T 19258-2012 specification, the service life of the ultraviolet lamp tube is not less than 5000h, the uniform service life is 8000h, and the high-performance product can reach more than 10,000 hours. Initiative consumer, every 1-2 years change, and every two weeks with alcohol wipe lamp tube surface surface, in order to ensure the radiation intensity of ultraviolet ray.Use ultraviolet sterilization lamp to want to control skill as a result of the destroy action of ultraviolet ray to biological cell, when using ultraviolet sterilization lamp, want to pay attention to do not want to reflect directly to human body skin, do not use the eye to look straight at lamp tube more. Under the premise of ensuring safety, how to use ultraviolet sterilization lamp scientifically and effectively? Rayven said, to pay attention to the position, create the best environment for use, and pay attention to the use time.As a result of ultraviolet ray penetrates ability to be very weak in the air, it is very difficult to reach far space sterilization ability, so when using ultraviolet sterilization lamp, want to be placed in main sterilizing position as far as possible, for example indoor in the middle, or the place that is easy to breed bacterium, interval is all round 1.5m-2m advisable. Attention should be paid to the effect of the environment on the bactericidal effect. Under normal conditions, the temperature between 27℃ to 40℃ ultraviolet output intensity is the largest, the bactericidal effect is the best, in addition to ensure the use of clean and dry environment, a large number of moisture and dust in the environment, will have interference with ultraviolet and weaken the effect, reduce the practice of ultraviolet intensity.

Ultraviolet lamp is a device that can emit ultraviolet light. It is a necessary tool for observing the fluorescence and phosphorescence characteristics of samples. It is also a physical method for sterilization and disinfection. It is widely used in medical, health and epidemic prevention, food industry, pharmaceutical industry and other departments. It is very important to use UV lamps correctly to ensure the sterilization effect and extend the service life of the lamp. So, what are the precautions for UV lamp disinfection?Methods of operate uv lamps1.       Ensure the correct disinfection method. Ultraviolet rays are mostly used for disinfection of air and surface of objects, wavelength 2573A. Used for air disinfection, the effective distance is not more than 2m, the irradiation time is 30 ~ 60min. It is used for article disinfection, the effective distance is 25 ~ 60cm, the irradiation time is 20-30min. Generally, the time starts from 5-7min. 10min, wait until the light is stable before applying; 2.       The lamp tube must be intact and correctly used, and the lamp tube should be regularly monitored. The intensity of the ultraviolet lamp tube should be replaced in time if the intensity is less than 70uwc / lining. The lamp tube should be kept clean. The surface of the lamp tube should be lightly tested with an alcohol cotton ball every 1 to 2 weeks to remove dust and grease to reduce the factors that affect the penetration of ultraviolet light; 3.       Keep the treatment room clean and dry at any time, and wipe the treatment room with a special rag soaked with disinfectant every day. Mopping the floor with a special mop to reduce dust and water mist, when the temperature is lower than 20 ℃ or higher than 40 ℃, and the relative humidity is greater than 60%, the exposure time should be properly extended; 4.       When sterilizing the surface of articles with ultraviolet rays, the irradiation surface should be directly irradiated with ultraviolet rays, and sufficient radiation dose should be reached. When disinfecting air, open all cabinet doors and drawers, etc., to ensure that all spaces in the treatment room are fully exposed Get ultraviolet radiation, disinfect as far as possible without dead ends;5.       During the disinfection process, the ultraviolet light source must not be exposed to people, especially the eyes, so as not to cause damage.
