solar garden lights outdoor led mistake

With the development of lighting technology in the lighting industry, the high-pressure sodium light source used in street lamps is gradually eliminated. LED light source is widely used in outdoor road lighting due to its high brightness, low energy consumption and energy saving advantages. At present, many people prefer to use solar led outdoor light because they have many advantages. But we know that no matter what kind of street lights may encounter some failures, when we encounter these failures, what should we do? How to prevent it?

　　Fault 1: solar led outdoor light flashes after extinguishing

　　 If the light source still flickers after the solar led outdoor light is turned off, this situation may be caused by the self-induced current generated by the solar led outdoor light itself. In order to solve this problem, we need to buy a 220 volt relay, connect the coil and the light source in series, so that the solar led outdoor light will not turn on.

　　 Fault two: solar led outdoor light brightness dim

　　The dimming of solar led outdoor light may be due to the poor quality of the LED chip inside the light source, which leads to large light attenuation. When choosing solar led outdoor light, we try our best to require street light manufacturers to use imported LED chips. In addition, the dimming of solar led outdoor light may also be caused by the burning of some lamp beads inside the light source. In this case, we should consider the capacitance or resistance of solar led outdoor light.

　　 Fault 3: Solar led outdoor light does not shine

　　The problem of solar led outdoor light not working is really worrying, so how do we prevent and solve this problem? First, we need to check the internal circuit of solar led outdoor light to see if there is a short circuit or the contact is not bright. If no problem is found after checking the circuit, it is a problem with the drive power supply. The driving power supply controls the voltage and current of the solar led outdoor light. If the voltage and current are too large or too small, the solar led outdoor light will not light up. At this time, we should replace the new drive power supply, try to choose a brand power supply, such as Mao Shuo or Wei Ming. The failure probability of this driving power supply is less than other power supplies.
