Problems solved by technology
The advantage of this solution is that it only uses one DC / DC circuit for driving, low production cost, good electromagnetic compatibility, and small PCB size, but it still has some disadvantages: the speaker should use a model with high input voltage, and the volume of this type of speaker Larger and more expensive, so the overall cost advantage of lamps is not big

The invention discloses a bluetooth-based LED music light, comprising an AC / DC conversion circuit, a bluetooth music module, a DC / DC circuit, an LED load and a speaker, wherein: the AC / DC conversion circuit is directly connected to the LED load, Power supply for the LED load; the AC / DC conversion circuit, DC / DC circuit and Bluetooth music module are connected in series with the speaker; the Bluetooth music module is connected to the AC / DC conversion circuit; the DC The / DC circuit is directly connected to the speaker to supply power to the speaker. The invention adopts the AC / DC circuit to realize the constant current function, which can directly supply power to the LED load, ensures that the size of the PCB is small, avoids the loss of efficiency on the DC / DC circuit, improves the efficiency, and is conducive to heat dissipation; no need to use Expensive and bulky high-voltage speaker power supply reduces the cost of the whole lamp, shrinks the volume, and is suitable for small-volume lamps; it does not need AC / DC conversion circuit to output excessive voltage, which improves the reliability of the Bluetooth music module.
Description
technical field [0001] The invention belongs to the field of power supplies, and in particular relates to an LED music lamp based on bluetooth control. Background technique [0002] LED lighting has the advantages of energy saving, long life, good color rendering and fast response, so it is widely used in people's home life. People's demand for intelligent LED lighting has prompted the rapid development of LED lighting technology. At present, LED lamps that can be controlled by mobile phones or remote controls through Bluetooth, LED lamps with music playback function, and other intelligently controlled multifunctional lamps have appeared on the market. Therefore, the driving power supply for such intelligent LED lamps has become one of the technical focuses of intelligent LED lighting technology. [0003] The existing bluetooth-based LED music lamp driving power mainly has the following two schemes: [0004] (1) The input alternating current is converted into a constant v...
