Abstract

The invention provides an LED light apparatus integrating a voltage-rise control module, replacing high-voltage power supply with low-voltage power supply for light string in serial/parallel connection, realizing power supply with dry battery or solar battery, and reducing the demand for electric grid power supply, thereby achieving green power. The light apparatus comprises a voltage-rise control module and LED lights, wherein the initial voltage, after being processed by the voltage-rise control module, is output. The voltage-rise control module further comprises: a working power supply, a pulse generator, a first triode whose base electrode is connected with an impulse signal output end of the pulse generator, a first rectifier diode with first end connected with the collector of the first triode and the second end being the positive electrode end of the final output voltage where the LED light is connected, a first filter in parallel connection between the second end of the first rectifier diode and the emitter of the first triode, and an inductor or resistor, with the first end of the inductor connected with the working power supply and the second end of the inductor connected with the first end of the first rectifier diode, or the first end of the resistor connected with the working power supply and the second end of the resistor connected with the first end of the firstrectifier diode.

Description

technical field [0001] The invention relates to an LED lamp device, in particular to an LED lamp device integrated with boost control inside. Background technique [0002] The current LED light strings are divided into two categories: low-voltage light strings and high-voltage light strings. High-voltage light strings refer to light string products that use alternating current or power conversion devices (such as transformers, AC / DC, etc.) and can provide power supplies higher than 5V (generally 6V, 12V, 24V, 48V, 110V, 220V). Low-voltage light strings refer to light string products that use dry batteries, button batteries, rechargeable batteries, solar cells, etc., and the working voltage of the light strings is below 5V, generally around 3V. [0003] High-voltage light strings can be connected in series and parallel, while low-voltage light strings can only be connected in parallel. [0004] Since the high-voltage light string requires a relatively high voltage, low-volt...
