Abstract

An LED lamp device integrated with a boost control module enables the original series-parallel lamp strings powered by high voltage to be powered by low voltage, realizes dry battery or solar battery power supply, reduces the demand for grid power, and realizes green energy saving. The technical solution is: the device includes a boost control module and an LED lamp, wherein the boost control module outputs an initial voltage after boost processing, and further includes: a working power supply; a pulse generator; a first triode, the base of which is connected to The pulse signal output terminal of the pulse generator; the first rectifier diode, the first terminal is connected to the collector of the first triode, the second terminal is used as the positive terminal of the final voltage output, and the LED lamp is connected here; the first filter, connected in parallel Between the second end of the first rectifier diode and the emitter of the first triode; inductance or resistance, the first end of the inductance is connected to the working power supply, the second end is connected to the first end of the first rectification diode, or the resistance The first end is connected to the working power supply, and the second end is connected to the first end of the first rectifying 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...
