- Q: The problem of residual light in LED lamp after power failure
- The power line can be switched to zero. The main switch is off and caused by a zero line.
- Q: What is the most bright Led band of white light?
- 3014 is white, 120 meters per bead of that, very bright. Yichang Galaxy Lighting City for your answer.
- Q: How much is the power consumption per meter?
- The small bulbs per meter of at least 30 (the interval of 3 cm), 15 meters close to 500, with the LED light emitting diode, each 0.05 watts of power, therefore, with a total power of 25 watts; as with ordinary small bulbs, each bulb power is about 0.2-0.3 watts, so the electric power 100-150 watts
- Q: What are the requirements for the LED light driver?
- When the load of the protection line is increased and the rated current is greater than 1.4 times, the protector can cut off the line after the time delay.
- Q: LED how is the band embedded in the steps?
- The LED lamp band is embedded on the steps: fixed on the steps with double-sided adhesive or glass adhesive or fixed clip.
- Q: 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.
- Q: How to connect the LED lamp with constant current drive?
- One end of the line connection method: one end of the LED tube is not connected, and the other end of the two pins are respectively lead to the constant current drive power. There is no connection between the two lamp holders. The biggest advantage is that if one end of the LED tube is connected to an alternating current, then the other end will not be charged. When replacing the traditional fluorescent lamp, you need to remove the original starter, change the starter fuse, and install the tube.
- Q: 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.
- Q: How do you calculate the current of the LED light belt?
- Non lighting each group current is about 10~20mA., each 3 lamps are a group. Lighting type about 50mA a group (different manufacturers, the current is also different), then you see how many lights, divided by 3 to get the number of groups, the number of groups of single current can get the total current
- Q: Which of the 12 volt LED light band and 220 volt LED lamp is brighter? What's the difference in electricity costs? Want to use it in the mall counter, 12 volts
- 12V is commonly known as low voltage line, and 220V is high voltage line.A few years ago, high voltage line technology is not mature, low voltage line can be broken, a chip at worst, in series near the other 2 (3 string). And then the high voltage line is bad, one will be bad on the whole meter.Later, the high voltage line technology mature, and now also three chips in series, pay attention to the procurement, ask the relevant personnel, do not buy the oldest high-voltage wire products on it. When I was 12, the hotel project was still using 12V, and now I've switched to 220V altogetherBrightness of the big difference, cheap 5-6 meters per meter (I have seen the cheapest, 2 meters a meter, no warranty), relatively bright manufacturers, ex factory price is 13. 5050 patch specifications, if you use high brightness chip wafer. (it's hard to find on the market.)
