1. LED lighting opportunities

Compared with traditional light source products, LED lamps have been generally regarded as a revolutionary and alternative technology due to their advantages of high luminous efficiency, long life, no mercury, and low total cost of ownership. With the implementation of the global incandescent lamp production ban and prohibition policies, incandescent lamps will gradually disappear from the market. In China, the National Development and Reform Commission announced that from October 1, 2012, the import and sale of incandescent lamps of 100 watts and above for general lighting will be banned nationwide, which undoubtedly creates huge opportunities for LED lighting companies.

In the face of the gradual enlargement of the LED lighting market, the rapid improvement of LED performance and the substantial cost reduction caused by the market competition of various merchants have brought the development of the LED industry. In the five years from 2008 to 2013, the LED lighting market has penetrated The rate has risen from 1.5% to 20%. It is expected that in the next five years, LED lamps will replace incandescent lamps and fluorescent lamps to a greater extent, accounting for most of the lighting market.

2. Bluetooth 4.0 technology caters to LED development opportunities

With the maturity and development of the LED market, in addition to replacing traditional lighting systems, LEDs can also be used with different technologies to make different applications.

In the field of LED lighting applications, wireless technology has gradually been integrated into the overall solution, with the concept of smart home. At present, the mainstream wireless transmission standards on the market are Wifi, Zigbee and Bluetooth. Among them, wifi consumes a lot of power and requires high equipment, while Zigbee is difficult and costly to develop. Therefore, for ordinary home lighting control, low-power Bluetooth 4.0 On the one hand, it breaks through the bottleneck of power consumption, and on the other hand, it is widely used in smart phones such as iphone, Samsung and HTC, which has advantages in both technology and cost.

3. Xinchida Bluetooth 4.0 LED light control solution

Xinchida's Bluetooth 4.0 LED light control solution is developed based on TI (Texas Instruments) low-power Bluetooth 4.0 chip CC2540. It uses four-way programmable PWM (120Hz) output to realize dimming applications, allowing smart phones that support Bluetooth 4.0 technology or Other mobile terminals replace all kinds of lights and remote controllers to control the LED lights.

When using this solution to operate, just keep the light powered on, open the corresponding mobile phone LED lighting control software, you can immediately establish a connection, intelligently control the lighting and color of multiple LED lights, and set the lighting time, brightness, and color temperature of the bulbs. Counting the power consumption of LED lights, etc., while feeling the convenience and speed of home lighting control, you can also enjoy the intelligence and fun of Bluetooth 4.0 technology in LED lighting control applications.

4. Program features and function description

1. Two modes of RGB three-color light control and single-color light control

A. RGB three-color light control mode

1. The three-color lamp can control the LED color through color cake or picture color selection.

2. The three-color light can automatically change color through music control LED. Automatic color change support (FLASH\STROBE\FADE\SMOOTH) four mode settings. You can create playlists by searching for music in your phone, and play music by playlist.

3. Three-color light custom color list function (20 groups, which can be recorded in a single LED light, as a list of colors that automatically change in a cycle after turning on the light regularly).

B. Monochromatic light control mode

1. The brightness of monochrome lights can be controlled by sliding the progress bar and preset values.

2. Monochromatic lights can automatically change the brightness and darkness of LEDs through music control.

2. LED light grouping control function

You can group multiple specified LED lights. After grouping, the grouped LED lights can be controlled and set according to the grouping, and the control effect similar to the marquee can be realized for the grouped lights according to the grouping order.

3. Timer timer switch function

Formulate a 24-hour cycle switch mode, such as timing on (17:00) and timing off (22:00), then it will be automatically turned on and off every day (monochromatic lights are on according to the set brightness, three-color lights according to the set color and setting. fixed mode automatically cyclically change).

4. LED lamp power consumption statistics function

Make statistics on the power consumption of each LED lamp (the average power does not consider the error caused by brightness adjustment and LED discoloration and the actual power, and the working time is accumulated to the minute each time).

5. Advantages of the scheme

1. Ultra-low power consumption, low carbon and environmental protection;

The core part of the LED bulb has a built-in Bluetooth 4.0 module, which follows the latest Bluetooth 4.0 low-power consumption standard. The power saving benefit is more than 10 times that of the traditional Bluetooth technology, and the standby loss is extremely low. LED lamp power consumption statistics function, keep abreast of power consumption, energy saving and environmental protection;

2. Automatic intelligence, control at will;

Once set, the color of the LED light will automatically change; the timer switch function of the LED light timer, 24-hour cycle switch.

3. "One" to "many" two-way control, simple and convenient;

A smartphone can be paired with multiple sets of bulbs at the same time, and multiple smartphones can also control a set of bulbs. In addition, a smartphone can carry out various controls, such as light bulb on/off, brightness and color.

4. The combination of "sound" and "color" is scientific and interesting;

By selecting music to control the automatic color and light and shade changes of LED lights, different "sound" and "color" are combined, which is an unusual and interesting experience;

6. Conclusion

Experts predict that smart lighting is expected to become the main force in the future smart home market. The Bluetooth 4.0 LED light control solution is a successful exploration in the field of smart lighting. With this solution, you can master home lighting with just a smartphone, and experience the fun of Bluetooth wireless light control. Plus, have a romantic candlelit dinner, have a crazy family dance…all of which can be achieved. In the era of wireless light control, the perfect result of LED smart lighting and home creativity will bring a very interesting and imaginative home life.
