Problems solved by technology
[0003] Existing solar lamps have two major problems: short service life of batteries and high cost of brightness adjustment
In this patented technology, the circuit lacks the battery charge and discharge protection function, so the service life of the solar lamps and lanterns is relatively low, and there are even potential safety hazards during the charging process of the battery
In addition, the brightness adjustment module of this patented technology uses MCU to complete the PWM output, which is very expensive and requires programming, so it is very complicated to realize brightness adjustment
The above-mentioned deficiencies make it difficult to promote the application of solar lamps and lanterns

The invention relates to a controller (20) and a solar lamp comprising the same. The controller (20) is used for controlling the solar lamp which comprises a photovoltaic component (10), a light-emitting diode (LED) light source (30) and a battery pack (40) and comprises an LED driving module (203). The controller (20) is characterized by also comprising a charging and discharging control module (201) which is connected with the LED driving module (203) and is used for protecting a storage battery from being charged and discharged excessively. The controller can also comprise a multi-pole dimming and switching module (202) which is connected with the LED driving module and is used for controlling the switch-on / off state and brightness of the LED light source. In the technical scheme, charging and discharging protection of the storage battery of the solar lamp and switch-on / off and brightness of the LED light source of the solar lamp are realized.
Description
technical field [0001] The invention relates to a controller and a solar lamp including the controller, in particular to a controller with functions of charging and discharging protection, multi-level dimming and switch control and a solar lamp including the controller. Background technique [0002] The world's energy shortage and environmental pollution are becoming more and more serious. Photovoltaic power generation utilizes unlimited solar energy reserves, has the advantages of no pollution and no noise, and has attracted the attention of all countries. At the same time, LED technology continues to develop, and its application in the lighting industry continues to grow due to its advantages of power saving and long life. The combination of photovoltaic power generation technology and LED technology has broad development space. [0003] There are two major problems in the existing solar lamps: the short service life of the battery and the high cost of brightness adjustm...
