LED bulb + smartphone =?

The picture below is an LED bulb recently launched by a company in Japan. At first glance, this is a plain light bulb without any peculiarities, but it is not. This light bulb has the features that traditional light bulbs can't. If you use a smart phone, this feature will be more prominent. So, what is the strange function of this bulb?

A: You can use more than 16 million colors of light on your smartphone.

“Before the lighting was a passive product, its existence was like 'air', but now it has become a 'happy” initiative. "Philips Electronics Japan (Headquarters: Tokyo) listed the "hue" home lighting system using LED bulbs in Japan at the end of September 2013. The system may subvert the concept of traditional lighting. The responsibility of the previous lighting is to provide light. The user only realizes the existence of the light when the light is broken. The operation of the light is basically limited to turning on and off the light, even if there is active operation, only the brightness is adjusted by the remote controller*1.

*1 Among the LED lighting lamps that have been commercially available, some products can use the remote control to adjust the brightness and light color according to the life scene.

But hue can use a smartphone to freely choose the color that is preferred from more than 16 million colors, and immediately let the light bulb emit the corresponding light. To this end, Philips has LED light bulbs with wireless communication capabilities, which can be controlled by smartphones via Bridge (included) and Wi-Fi routers. The left side of Figure 1 shows the free app for smartphones provided by Philips. On this screen, [1][2][3] is placed on the favorite colored pencil by touch operation, and the LED bulb will immediately emit *2 according to the specified color. In order to express more than 16 million colors, Hue is equipped with red (R), green (G), and blue (B) LED elements*3 inside each LED bulb.

Figure 1: By touching the free application in smartphones and tablets, change the color of [1][2][3] to any position, and the LED bulb will emit the corresponding color.

*2 A similar usage is that if you specify the location of [1][2][3] above on any photo saved in your smartphone, the light will emit a corresponding color of light, and the user can immerse himself at home. In the good memories of travel.

*3 hue costs more than traditional products. The price of each LED bulb of hue is 6,980 yen.

You can also implement a unique new usage of your smartphone. Users can use the GPS function of the smartphone to turn on the hue's light bulb automatically when they go home, or turn off the lights automatically when they leave home. Moreover, for added security, the lights can be turned on when no one is at home, or turned off at any time, which can be remotely operated using a smartphone.

Figure 2: You can use your normal home lighting fixture to call up your favorite light color. Supports the use of E26 lamp illumination.

Hue supports the E26 socket for general lighting specifications for home use, so it can also be used for low-cost lighting fixtures purchased at home stores, etc., to illuminate according to the user's favorite color (Figure 2).

The application of the transformers we produce:

1. Building Automation and Control Systems

In modern buildings, power transformers are used to supply power to building automation systems, including lighting control, HVAC (heating, ventilation, and air conditioning) systems, and security systems.

They convert the main power supply to a safe and manageable voltage level, ensuring optimal performance and reliability of these systems.

2. Industrial Control Panels and PLCs (Programmable Logic Controllers)

Industrial control panels and PLCs require precise and stable power supplies to function correctly. power transformers provide clean, filtered power to these devices, minimizing interference and ensuring accurate control.

3. Machine Tool and Automation Equipment

In manufacturing and production facilities, power transformers are used to power machine tools, automation equipment, and robotic systems.

They ensure that these devices operate at the correct voltage level, preventing damage and maximizing productivity.

4. Low-Voltage Electrical Distribution

power transformers are essential components in low-voltage electrical distribution systems, where they convert the main power supply to the required voltage level for distribution to various loads.

This includes supplying power to outlets, lighting fixtures, and other electrical devices in commercial and residential buildings.

5. Audio-Visual and Entertainment Systems

Audio-visual and entertainment systems, such as sound systems, stage lighting, and projection equipment, often require power supplies.

power transformers provide clean, stable power to these systems, ensuring optimal performance and minimizing interference.

6. Medical Equipment and Laboratories

Medical equipment and laboratories require precise and reliable power supplies to ensure accurate measurements and safe operation.

power transformers are used to supply power to various medical devices, laboratory instruments, and testing equipment.

7. Renewable Energy Systems

In renewable energy systems, such as solar and wind power plants, power transformers are used in energy conversion and distribution processes.

They help in stepping down the generated voltage to a level suitable for distribution to the grid or for use in local loads.

8. Backup Power Systems

Backup power systems, including uninterruptible power supplies (UPS) and emergency generators, often incorporate power transformers.

These transformers ensure that the backup power supply is delivered at the correct voltage level, maintaining power continuity during power outages.

In summary, power transformers are vital components in numerous applications where safe, reliable, and efficient power distribution is essential. Their ability to convert and distribute electrical energy at low voltages makes them ideal for use in building automation, industrial control, machine tools, low-voltage electrical distribution, audio-visual systems, medical equipment, renewable energy systems, and backup power solutions.
