A set of positive yellow light beads and a set of positive white light light beads are installed inside the light shade. Each set of light beads is respectively connected to a corresponding control circuit. Each set of light beads consists of 15 Composed of 3 and 45 LED lamp beads in series, the output current of each group of lamp beads is a maximum of 450mA, and the voltage is 45V-50V; the control circuit includes a Bluetooth control circuit, a pulse width modulation programmable controller circuit and a constant current drive circuit. The advantages of the present invention are: the brightness and color temperature can be automatically adjusted according to the external environment, or the user can customize various scene modes through the bluetooth communication of the mobile phone, and select the appropriate brightness and color temperature. For example, the reading mode can provide the maximum brightness and daylight color temperature. Sleep mode can reduce the brightness and color temperature of the night light and automatically turn off the light with a delay, etc.

Description

A mobile phone bluetooth control LED ceiling lamp

technical field

The invention relates to a mobile phone bluetooth-controlled LED ceiling lamp.

Background technique

Ceiling lamps are commonly used lamps in family bedrooms, living rooms, and study rooms. The existing lamps have a single color and constant brightness. With the improvement of living standards, people hope that lamps can have more color and brightness changes, be more energy-saving, and have certain intelligence. function, can improve the taste of home life; mobile phones are widely used at present, if the brightness of LED lights can be controlled by mobile phones, it will not only improve the intelligence of the home, but also facilitate people's lives. Therefore, a mobile phone that can be controlled by Bluetooth is needed. LED ceiling lights.

Contents of the invention

The purpose of the present invention is to provide a mobile phone bluetooth control LED ceiling lamp, the specific scheme of the present invention is:

An LED ceiling lamp with adjustable brightness and adjustable color temperature, including a lampshade. A set of positive yellow light beads and a set of positive white light beads are installed inside the light shade. Each set of light beads is respectively connected to a corresponding control circuit. Each set of light beads All are composed of 15 strings of 3 parallel LED lamp beads, the output current of each group of lamp beads is 450mA, and the voltage is 45V-50V; the control circuit includes Bluetooth control circuit, pulse width modulation programmable controller circuit and constant current Drive circuit.

The pulse width of the pulse width modulation programmable controller circuit is controlled by a photosensitive control circuit and a timing circuit; the constant current drive circuit is provided with a DC power supply by a rectification and filtering circuit.

The advantages of the present invention are: the brightness and color temperature can be automatically adjusted according to the external environment, or the user can customize various scene modes through the Bluetooth communication of the mobile phone, and select the appropriate brightness and color temperature. For example, the reading mode can provide maximum brightness and daylight color temperature. Sleep mode can reduce the brightness and color temperature of the night light and automatically turn off the light with a delay, etc.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

An LED ceiling lamp with adjustable brightness and adjustable color temperature, including a lampshade 1, a set of positive yellow light beads 2 and a set of positive white light beads 3 are installed inside the light shade, and each set of light beads is respectively connected to a corresponding control circuit 4, 5 connection, each group of lamp beads is composed of 15 strings of 3 and 45 LED lamp beads, the output current of each group of lamp beads is a maximum of 450mA, and the voltage is 45V-50V; the control circuit includes a Bluetooth control circuit, pulse width modulation programmable Controller circuit and constant current drive circuit.

The pulse width of the pulse width modulation programmable controller circuit is controlled by a photosensitive control circuit and a timing circuit; the constant current drive circuit is provided with a DC power supply by a rectification and filtering circuit.

The timing circuit and photosensitive sensing circuit are used to work in the "automatic" mode. When the time is from 6:00 to 18:00 in the morning, the pulse width modulation programmable circuit gives a signal to control the constant current output circuit 2 for the LED white light group to work. The brightness is automatically adjusted according to the strength of the ambient light sensed by the photosensitive circuit to achieve the best energy consumption ratio; when the time is 6 pm, the pulse width modulation programmable circuit controls the constant current output circuit to work for the LED yellow light The brightness is automatically adjusted according to the strength of the ambient light felt by the photosensitive circuit to achieve the best energy consumption ratio; the timing circuit can also be customized by the customer to turn on or turn off the light at a fixed time. The bluetooth control circuit is used to receive signals from smartphones, and can also receive control signals from wireless routers for remote control with mobile phones. Multiple modes can be set. In sleep mode, it will automatically switch to night light after 10 minutes. The color temperature is yellow and the brightness is 5% of the overall power; in reading mode, the color temperature is white light, and the brightness is 100% of the overall power; in horizontal mode, white light and yellow light are mixed in proportion to emit light; the brightness and color temperature can also be "manually" adjusted through the mobile phone, and the brightness is at the total power It can be adjusted between 5%-100%, and the color temperature can be adjusted between 2700K～6400K.

The above has disclosed the present invention with preferred embodiments, but it is not intended to limit the present invention. All technical solutions obtained in the form of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
