FAQ
- Waterproof LED lamp belt used after a period of time, there is a part of the lamp with white into orange, what's the matter?
- Waterproof lamp with 3 waterproof glue, waterproof casing, gluewaterproof.The three lights in the process of using the glue properties will produce oxidation, with epoxy glue, glue, glue sleeve.After the oxidation may have a slight color, slightly yellow, light color after visual orange emission through the surface of the glue in may.
- Why does the LED band suddenly go dark?
- Service condition problem:1, LED for constant current drive, there are some LED voltage driver, cause LED attenuation.2 、 the driving current is larger than the rated driving condition.In fact, there are many reasons leading to degradation of LED products, the key is the heat problem, although many manufacturers in the secondary products do not pay special attention to the heat problem, but the long-term use of these secondary LED products, attenuation degree will be higher than a focus on cooling LED products. The LED chip itself, thermal resistance of silver colloid influence, substrate cooling effect, and also with colloidal gold and light attenuation relationship.
- According to the LED lights, how to judge the quality of the products?
- Look at the cleanliness of the surface of the LED lamp band. If the LED belt produced by SMT process, its surface cleanliness is very good, and no impurities or stains can be seen. However, if you use hand welding process produced cottage version of LED lights, regardless of how the surface cleaning, there will be traces of stains and cleaning, and at the same time on the surface of FPC will have soldering flux and tin residue.
- How do you charge for installing Led lights?
- For engineering projects, calculate the number of lights required. It should be noted that the band can be divided into three groups of shearing use, generally 60 per meter of light belt, each length of 50mm, 30 meters per band, each group length of 100mm. After you know this, you can calculate the actual number of lights used in accordance with the construction effect diagram. Generally reserve about one meter or so spare length, so as to avoid excessive procurement, resulting in waste of resources.
- 5050 per meter, 60 beads, led band power consumption is about how much watts?
- Power consumption (w / M): 11.52-10.55Luminous color: whiteLamp socket interface (lamp holder model): T tubeApplicable voltage: 220VSpecification (lamp / meters): 60Band style: Patch
- What's the light belt? What's the use of the LED light?
- The light belt is the abbreviation of the LED light belt. Most people are not accustomed to the noun when they say it is too long, so the LED in front is omitted. It is called the light belt directly. In this way, the band with the name also includes a lot of big, second line, big three lines, round, second line and so on, the direct use of wire to connect LED, instead of FPC or PCB old band, of course, also includes flexible light band and hard light belt.
- What's the LED band?
- LED lamp belt price is generally in meters as a unit, cheap 10 yuan or so: quality is more general, can do home decoration, or other use time comparison case use. The quality is better, the quality is about 30~50, and its service life is longer
- LED lamp belt installation uneven lighting, how to do?
- The slot of the lamp belt is usually 300 of the height of the ceiling, and the width is 200! Also, the distance in the light belt depends on what kind of uniformity you want to achieve!
