solar led light outdoor provides lighting and security for people traveling at night. Solar led light outdoor manufacturer is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, solar led light outdoor will become the choice of road lighting energy-saving transformation. Solar led light outdoor is a kind of high-efficiency solid-state light source formed by semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, it injects holes in the P area and injects into the N area. After the electrons diffuse into the active area, they recombine through radiation to emit photons, which directly convert electrical energy into light energy. The government really serves the people and the people are very satisfied.

After the electrons diffuse into the active area, they recombine through radiation to emit photons, which directly convert electrical energy into light energy. But after a while, I found that the lights at night were not as bright as usual, so I quickly reported the situation to the relevant person in charge, and the relevant person in charge quickly contacted the solar led light outdoor manufacturer. The manufacturer replied that the lights could not be turned on after dark due to the following reasons.

　　 One, voltage

The controller shows that the battery is under pressure and cannot be illuminated after dark, but the battery voltage has exceeded this point under the pressure value, indicating that the battery has been charged. In a 12v system, the lower voltage protection value is about 11.1v (controller default value). After the battery drops to this voltage point, the controller will turn off the power, stop discharging, protect the battery but release.

  the reason

Solar panels charge the battery during the day and charge the voltage to 12V (the default value of the controller) before continuing to discharge to prevent the battery from being damaged by deep discharge for a long time. Then, after the battery is under-voltage, if the controller does not restart, 11.1 or 12V is under-voltage state, you must wait for the battery to recharge to 12V, and then continue to discharge.

  Solution

It is sufficient to charge the battery voltage to 12V or higher using solar panels or a DC charger.

　　 2. Controller

If solar led light outdoor has been installed and can be turned on normally for a period of time, the controller will fail. The reason for the damage of the controller is that the system is subjected to strong electric shock, such as direct lightning strike or short circuit, or the internal electronic components of the controller may be damaged.

  Solution

Replace the controller, test the controller, and check the response of the indicator light. If neither indicator light is on, the controller will be damaged and must be replaced.

3. The light source is driven by DC power supply.

The indicator light of the detection controller shows normal discharge and the battery voltage is sufficient, that is, the light is off. At this time, the positive and negative poles of the lamp should be directly connected to the positive and negative poles of the battery. If it cannot be discharged, the DC power supply of the light source will be damaged. Need to be replaced. Now the light source DC power driver is integrated with the controller in the aluminum box. Installation and maintenance are simpler and more convenient. If a component is damaged, it can be replaced directly.

Why doesn't solar led light outdoor light up after dark?
