LED lights are efficient and environmentally friendly lighting products. Compared to traditional incandescent bulbs, LED lights have higher energy efficiency, longer lifespan, and better color rendering.
However, the electrical characteristics of LED lights are different from traditional lighting fixtures, especially when it comes to calculating current, which requires more careful consideration.
In this article, I will provide a detailed introduction to the method of calculating current for 12-volt LED lights, as well as how to reduce the current of LED lights. I will also introduce the lighting products of the KOSOOM brand.
What is LED lighting?
1、Working principle of LED lighting
The term “light-emitting diode,” or LED, refers to a device whose operation relies on the photoelectric effect of semiconductor materials. Electrons are excited from a low energy level to a high energy level when current flows through a semiconductor material, releasing photons of energy, or light.
The lighting industry is seeing an increase in the use of LED lights since they outperform traditional incandescent bulbs in terms of luminous efficiency and lifespan.
2、Benefits and drawbacks of LED illumination
Despite having some drawbacks, such as a high initial cost and uneven light intensity, LED lights have many benefits, including high energy efficiency, a long lifespan, shock resistance, and environmental friendliness. However, as technology continues to advance, a wider range of applications for LED lights in the lighting sector are becoming possible.
LED light power and current
1、LED light power
The energy used by an LED light per second, expressed in watts (W), is referred to as the LED light’s power. In contrast to conventional incandescent bulbs, LED lights typically have power outputs between 1 and 20W.
2、LED light voltage
The quantity of electrons flowing through an LED light is referred to as its current and is expressed in amperes (A). The voltage and LED resistance values must be known in order to compute the current of an LED light.
Current equals voltage divided by resistance, in accordance with Ohm’s law. In general, the current can be computed using the formula shown below for a 12-volt LED light:
- Current (A) = Voltage (V) / Resistance (ohms)
However, the resistance value of an LED light is not a fixed value, but varies with temperature. Therefore, the change in resistance value must be considered when calculating the current. In addition, different types of LED lights have different current requirements, and the current should be calculated based on the actual situation.
How to reduce the current of LED lights
There are several ways to reduce the current of LED lights:
- Choose the appropriate resistance value:
Select the appropriate resistance value according to actual needs to ensure that the LED light current meets the specified requirements.
- Use an LED driver circuit:
The LED driver circuit can adjust the current and voltage according to actual needs, thereby achieving precise control of the LED light.
- Use a PWM controller:
The PWM controller can control the brightness and current of the LED light by adjusting the duty cycle of the PWM wave, achieving the goal of reducing the current of the LED light.
