LED Holiday Light introduction: LED Christmas light […]
LED Holiday Light introduction: LED Christmas light intelligent controller, which is characterized in that it includes LED Christmas light driving power supply, H-bridge circuit, lighting mode controller, Bluetooth module, manual button and Bluetooth module, the LED Christmas light driving power supply The H-bridge circuit is connected; the lighting mode controller is connected to the H-bridge circuit; the lighting mode controller is respectively connected with the Bluetooth module and the manual button; and the output of the H-bridge circuit is connected to the dual LED string. The scheme adopts the Bluetooth technology of the smart phone to remotely control the lighting mode of the Christmas lights, which brings a sense of convenience to the user, and brings the highlights of technological innovation to the Christmas lights, and also brings a new selling point to the Christmas lights. .
1. LED Christmas light intelligent controller, which is characterized in that it comprises LED Christmas light driving power supply, H-bridge circuit, lighting mode controller, bluetooth module, manual button and bluetooth module, the LED Christmas light driving power connection H bridge The output of the lighting mode controller is connected to the input end of the H-bridge circuit; the input end of the lighting mode controller is respectively connected with the Bluetooth module and the manual button; the output of the H-bridge circuit is connected to the dual LED string; The Bluetooth module is wirelessly connected to the Bluetooth module of the mobile phone.
2. The intelligent controller according to claim 1, wherein the H-bridge circuit is composed of four switch transistors, the transistor type: the upper tube is a PNP type transistor M8550, and the lower tube is an NPN type transistor M8050.
3. The intelligent controller according to claim 1, wherein said LED Christmas light driving power source comprises a series connected rectifying circuit and a DC-DC converting circuit.
4. The intelligent controller according to claim 1, wherein said Bluetooth module comprises a signal processing module and a control circuit connected in series, said signal processing circuit converting a wireless signal obtained from a mobile phone into an electrical signal; said controlling The circuit converts the electrical signal into a level pulse signal.
LED Christmas lighting drive power, especially the innovation of the control circuit of the rear-level lighting mode involving the driving power supply, specifically a Bluetooth intelligent control circuit.
LED Christmas lights have a large market, but they are very seasonal products. Orders are mostly from six months ago to one year ago. That is to say, most of the products developed by the manufacturers will appear in the terminal market at the end of the next year. Therefore, product development in the field of LED Christmas lighting must be diversified, novel, and low-cost to meet the international market. Demand.
Currently, digitally controlled Christmas lights produced on the market,
For the button mode to control the conversion of the lantern lighting mode, the lighting mode of the lantern is: single-channel fast flashing, two-way fast flashing, one-way gradually fades out, two-way fades out gradually, single-channel is always bright, double Lu Changliang and various lighting combinations cycle mode and so on. In the case of button-based control, it is inconvenient to press the button on the drive power supply to change the lighting mode, which is not suitable for a modern fast-paced lifestyle.
According to the current situation that the Christmas lights on the market are button-type lighting control mode, this program uses the current science and technology, based on the Bluetooth technology of the smart phone, to transform and innovate the new type of Christmas using the Bluetooth technology intelligent remote control Christmas lights lighting mode. Light products.
In view of the inconvenient operation of the operation mode of the current stage controller of the Christmas lantern driving power supply, a smart remote control based on the smart phone is proposed, and the Bluetooth remote control Christmas lantern controller is innovatively used. Choose the lighting mode you want.
