LED crystal light is broken, what should I do if it is not lit?
LED crystal lights are essential in indoor lighting environment, but how to deal with them?
LED crystal lamps are generally used in ceilings, hoisting, ceiling mounted, various types of LED crystal lamps are available, the following decomposition of crystal lamps from all aspects of the problem.
Even though there are thousands of crystal lamps on the market, they are just different in appearance, and the principles are the same. What if the crystal light does not light up?
Here are the answers for everyone: 1. Line problems; 2. Accessories problems, one by one, check and eliminate one by one.
Line problem
The line problem is well understood, that is, there is no electricity to supply the crystal lamp. Check method: If there are conditions, you can use the test pencil (also known as the electric pen) to measure, if there is a multimeter to measure better. The specific method: at the 220V access point to measure whether there is no electricity to supply the crystal lamp, if not, then it is the problem of the line, there is no electricity to supply the crystal lamp, to solve the line power supply problem. If there is power supply, then it is the problem of the crystal lamp itself (crystal lamp accessories), please look down the solution.
Accessories reason
Before looking for the reason for the accessories, let's first understand the basic accessories of the crystal lamp:
LED crystal lights have the following accessories:
1. LED light board, generally has a round shape, a long strip, and also has a special shape according to the shape of the crystal lamp. The hoisting crystal lamp has a light board which is generally a round light board, and the ceiling crystal lamp is generally a long strip shape. Light board.
2. LED bulbs , generally LED candle bulbs, E14 interface, the wattage is not too big, usually about 3, 5 watts, LED bulbs usually have their own power supply, directly connected to AC220V.
3. Drive power, also known as transformer, popularly speaking, is to turn 220V into DC low voltage, for the aforementioned LED light board. There are a variety of driving power sources, ordinary direct lighting board, and also with controller, with controller can multi-channel output, to control multi-channel LED lights, to achieve crystal light color temperature, brightness, color.
After the accessories are introduced, look for the reasons below:
1. Light bar, light board is not bright
The light bar and the light board are not lit. The role played in the crystal lamp is the same, always bright, or the color of the crystal lamp changes color, brightness, and color change through the control of the power supply.
Multiple sets of light bars are not bright. If the multiple sets of light bars are connected to the same drive power supply, it may be that the drive power supply is broken. The drive power can be replaced according to the voltage of the light bar.
The single group of light bars is not bright. If the light source connected to this group of light bars is connected to other light groups, the other light groups are good, then the light bar is broken and the light bar is changed.
If the single LED light is off, it is determined that the LED light is broken and the entire LED light bar needs to be replaced.2.LED bulb does not light up
LED bulbs are generally replaced with new ones. It should be noted that the bulbs need to have a constant current source. Although the resistance is cheap, it does not take long. Plastic bulbs are not recommended. According to long-term use, plastic bulbs are not well cooled. In summer, the temperature is high and the use time is prone to be bad.
3. The drive power is broken.
If the normal drive power supply is broken, all the connected light groups will not be bright, and the drive power supply needs to be replaced. The drive power supply should pay attention to the selection of good quality drive power, good workmanship, good quality drive power is actually not expensive, specific The reason is to look down.
The drive power supply with control function is broken. If it is controlled by multiple channels, it may not be lit all the way, and many roads are not bright, and can be replaced.
Well, the basic point that the crystal lamp is easy to break has already been said, and there may be other problems. At the same time, welcome feedback and see the answers. At the end of the day, the difference between LED crystal lamps and other lamps is that the price may be more expensive. In fact, LED crystal lamps sell in shape, so don't be blinded. The accessories of crystal lamps are not expensive.
Satellite broadcasting has the characteristics of wide frequency band, large capacity, stable and reliable performance, wide coverage and suitable for various services. It has become the main means of transmission for radio and television. The performance of satellite ground receiving antenna is directly related to the GH/T value of satellite ground receiving equipment, which determines the viewing quality of satellite broadcasting and TV programs. Therefore, the right choice of satellite receiving antenna is an important premise and guarantee of satellite receiving. Satellite ground receiving station basically chooses two kinds of antenna, namely parabolic antenna (feedforward) and cassegrain antenna (feedback). Parabolic antenna consists of a rotating-symmetric paraboloid, that is, the electromagnetic wave reflection surface and the feed surface, the feed surface in front of the paraboloid
