Low-cost Bluetooth ad hoc network LED drive circuit

Abstract

The invention discloses a low-cost Bluetooth ad hoc network LED drive circuit. The LED drive circuit comprises an AC / DC constant-voltage constant-current conversion circuit, a Bluetooth power supply circuit, a light source drive control circuit, an MLE-Mesh module and a Bluetooth signal processing control module, wherein the AC / DC constant-voltage constant-current conversion circuit is connected with the Bluetooth power supply circuit and the light source drive control circuit, and the AC / DC constant-voltage constant-current conversion circuit and the light source drive control circuit are both connected with a luminous source; according to the invention, through intelligent sound equipment connection and voice control of a mobile phone APP, the wireless control distance is long and signals are stable , through the Bluetooth nodes, the LED drive circuit can be self-organized, set in any light scene, turned on and turned off in a timing manner and dimmed, the timing scene can be turnedon and turned off, voice instructions of multiple languages can be received, and the intelligent life requirements can be met. Each path of the 3 paths of R-G-B output circuits is independently controlled by a constant-current circuit, out-of-control of the LED drive circuit due to signal faults is avoided, and the reliability is high; and moreover, the MOS tube Q8 is controlled through warm lightdimming and the MOS tube Q9 is controlled through white light dimming control to pass through U1 and a surrounding circuit constant current, so that the cost is low, and the benefit is high.

Description

Technical field [0001] The invention relates to the field of lighting circuit technology, in particular to a low-cost Bluetooth ad-hoc network LED drive circuit. Background technique [0002] In daily life, lamps such as downlights, panel lights, floodlights, ceiling lights and spotlights are relatively common lighting products. However, these lighting products have relatively single functions. With the rapid development of the Internet of Things technology, people's material and cultural life needs continue to increase. In the past, ordinary lighting products have gradually been unable to meet the needs of pursuing intelligent situational life. Summary of the invention [0003] In view of this, the main purpose of the present invention is to provide a low-cost Bluetooth ad hoc network LED drive circuit in view of the deficiencies in the existing technology, which can effectively solve the problem that the existing lighting products cannot meet the needs of pursuing intelligent si...
