Q: LED lamp belt, why turn off, still bright, seek expert solution: Because of your LED light line, the switch control (off) is zero line. You might as well see if there are any other fluorescent lights or LED lights off at home. If there is, the bus FireWire and zero line exchange, and if only this one, then the LED lights line for FireWire and zero line swap, this phenomenon will disappear.

Q: 50 cm long LED lamp band for temporary lighting, please use AC transformer or DC transformer: If you need to connect the transformer, then certainly need DC, to distinguish positive and negative poles.

Q: What type of LED lamp comes with the brightest light?: In two different manufacturers, using the same patch made of light, brightness may not be the same, LED is the current device, current is, the higher the brightness, some manufacturers in the pursuit of brightness and low cost, will increase the current to improve the brightness, life will be a lot worse, especially white. You can solve the problem that: 5050 led domestic manufacturers with some formal, ask the clerk to provide product specification, comparison of various manufacturers specifications on luminous flux values, a large number of lumens brightness generally high, of course, do not forget to consider the half angle.

Q: What is a light belt?: LED Strip. This is the English name for the LED light belt. The interpretation of Strip in Yahoo translation is "strip", and the interpretation in Google is "small strip", but the LED light carries the word "LED Strip" in the mouth of foreign customers

Q: LED is the light belt good? What lamp does the home outfit take well with?: Look at their own home style, what I bought the yellow light lights, but it should buy white light will be better, the yellow light is too dark, be sure to buy good quality, I did not open for three days on the flash several, my 19 meters

Q: Embedded LED lights with notches generally go deep enough: Under normal circumstances, are 810, two widths of the band shape, but there is better aluminum, hard light bar, then there are about 18 wideSo first you have to figure out the model of your lights, it is best to have pictures to understandIf not, then use the maximum range of 18 wide, the deepest depth of about 15, this is the largest range of light belt

Q: What kind of power supply should the LED light belt be equipped with?: DC current source output current is constant, when changes in the number of LED lamps series the automatic voltage regulation, and output current in a certain range remains unchanged, if there is a LED lamp open circuit fault occurs when the local pressure at both ends of the breakdown fault LED lights, LED lights, the road is short and other light work as usual. When the LED current in series is not the same, it will cause uneven brightness.

Q: How do I choose the light belt?: Light color choice belt mainly according to the customer's own style of decoration and color to determine the general Jiezhuang recommended with warm white, the color is yellow and white light color comfort, moderate brightness, decorative effect is warm. White LED decorative effect, clean and tidy. Light color consistency is good, suitable for simple style. The yellow light effect LED tone warm, but because the Yellow LED lamp luminous efficiency is not high, light is dark, so the color is dull. The use of more than the recommended number. Blue can be placed in the bar, the effect of the dream is fresh, whole room decoration ring can also highlight the glamorous and elegant style of decoration. The red and green light belt needs to be used with the background. It is not recommended. The color light needs to be coordinated with the controls. It can be used in audio-visual rooms and other decorations.

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: Home decoration, lights band 5050 and 3528 what is the difference?: The first is the process of LED welding in copper wire above, then put the PVC pipe or equipment used in direct forming, round and flat two, named according to the number and the shape of the lamp wire belt to distinguish between two lines called, round in front with a round, round or flat line; in front with flat characters, namely flat line. Later developed into a flexible circuit board is used FPC as carrier, because of its simpler processing technology, quality is easier to control, longer life, higher brightness and color, and gradually replaced the earlier process, become the trend.Because the lamp belt is generally welded LED, so there are many LED lights, but because the noun is too long and simplified into a band.
