Problems solved by technology
There are many disadvantages in using this kind of connection method for holiday light strings: the current of each parallel circuit is different, resulting in inconsistent brightness of each LED unit; The usage rate is greatly reduced. At the same time, because of this kind of loss, the number of LED units that can be connected to a light string is limited. Generally, this kind of LED festival light string on the market can only connect about 200 units at most; this kind of connection method is very important for the production of LED The rated voltage and rated current requirements of the LED units used in festival light strings are also relatively strict, and the process is more complicated, and more wires are used for connection.

Embodiment Construction
[0014] Such as figure 2 As shown, a solar LED holiday light adopting a parallel mode, the solar cell 1 charges the storage battery 2 under the control of the light controller 8, when the sunlight is sufficient, the charge of the solar cell 1 is greater than the charge of the storage battery 2, and vice versa The circuit is then cut off to prevent the battery 2 from being reversely charged into the solar battery 1, causing unnecessary waste. The battery 2 passes through the low-voltage high-efficiency oscillator 3 and the triode 4, and completes the transition from low voltage to high voltage under the action of the high-voltage generator connection 5 Converted, and then filtered and rectified, connected to the current output control system 6 controlled by the light controller to output to the LED series light string 7. At this time, the light controller can effectively prevent the static loss of electric energy by the output control system.

A solar LED holiday lamp comprises a storage battery, a solar battery board connected to the input end of the storage battery, a light controller, a low-pressure high-frequency oscillator, a triode, a current output control system, and LED lamp series. Voltage rises through a high-pressure generator before working on the LED lamp series, and units of the whole LED lamp series are connected in series through the output control system. The invention ensures the consistent brightness of the LED units of the whole lamp series, has high electricity use ratio, effectively saves the use amount of wires, saves energy, protects environment, and can connect a plurality of LED units at the same time.
Description
technical field [0001] The invention relates to a solar festival lamp, in particular to a solar LED festival lamp with a high-voltage generating device. Background technique [0002] That is, some solar LED holiday lights generally use a voltage of about 3.6V. The LED units of the entire festival light string are usually connected in parallel. In order to meet the needs of different colors of LED light, and to ensure the voltage of each parallel circuit, Each LED unit needs a power resistor in series, such as figure 1 As shown, the red LED unit 801 is connected in series with an effective resistor R01, while the green LED unit 802 needs to be connected in series with another specification of the effective resistor R02, and so on. Different colors of LED units require different series resistors to emit light. There are many disadvantages in using this kind of connection method for holiday light strings: the current of each parallel circuit is different, resulting in inconsis...
