How does Bulb 3157K work?
3157K is the new member of the bulb family. It has the same standard E27 base as other bulbs but this bulb operates on a different principle.
3157K consists of 4 parts:
* LED module – high quality, special for this bulb;
* Photovoltaic cell ;
* A set of electronic components that include phototransistor, inductor, and capacitor, etc.;
* Bulb shell.
The LED module lights up when the built-in photovoltaic cell is exposed to light. When it is dark, the phototransistor blocks current from the LED, and the bulb shell is completely un-lit.
Photovoltaic cells consist of two layers: semiconductor and metalized contact grid. Built-in capacitor stores electricity and supplies it for LED modules when electrical power is needed(in low-light conditions).
The inductor is used to convert power from electronic components. Voltage from the inductor creates a magnetic field around the LED and this is how it illuminates.
In night or dark conditions, the LED module receives a tiny amount of current from the photovoltaic cell via an inductor. Current is stored in a built-in capacitor and released to the LED module during low light conditions via the inductor.
In a day or bright conditions, the photovoltaic cell doesn’t need any current because a large amount of it is supplied to the LED module via a built-in phototransistor from solar energy.
Bulb shell covers all internal parts and protects them from dust, dirt, and moisture.
Bulb shell is made of transparent plastic and has a matte finish. This provides diffusion of light and prevents any unwanted reflections.
3157K can be used as an original bulb replacement in your household. 3157K is best suitable for cars, trucks, motorcycles, boats, airplanes, etc., where a bright light beam without glare is required.
What is the expected lifetime of Bulb 3157K?
Expected lifetime of Bulb 3157K is 30,000 hours. This means that when your bulb would operate 4 hours per day, its replacement should happen after 10 years.
The Bulb 3157K is a perfect example of how the introduction of new technology can change so many aspects of our lives. It’s no surprise that this type of innovation has led to more efficient and cost-effective ways for people all over the world to light their homes. If you’re in need, come see us at Ace Hardware!
