Home » J&S Lighting latest articles » Comparative Analysis of 12V and 220V LED Strip Lights

12V led strip lights is low-voltage electricity, and 220V electricity is for civilian use. You could also say that the input voltage of 220V is the same as the working voltage, which is 12V.

The light strip 220V is easy to use and is directly connected to the power supply 220V, but it is not risk-free.

The low-voltage 12v led strip lights are more secure. When you connect them, however you must connect a transformer before it can be connect-ed to the power supply.

The 220V light strip is a converter equipped with rectifier and constant current output inside. The output voltage of the rectified and filtering plug is 300V DC.

By converting constant current, it regulates the output current to be 10 milliamperes of DC to power the LED light strip. The 12V strip of light doesn’t contain the converter, but 12V DC is used to power the LED strip.

LED Selection Parameters and 12v Direct Drive Led Strip Lights

To begin, let me ask a question, can 12V directly power a light-emitting diode in series with the help of a resistor?

The maximum operating current for LED lamp beads with low power with a variety of shades is typically 20mA. However, the actual value ranges between 5 and 15mA.

The drop in forward voltage for red LEDs usually 1.62V. Green ones generally 1.82.4V and white or blue are 33.3V.

Assume that a blue lamp bead is drive-n with a 12V power source and the operating power is 9mA. Then, the resistor that limits current R equals (12V-3V/9mA) = 1KO. The voltage drop forward for the blue lamp is 3V.

I chose an LED however, I ran into some issues when I was driving it. Even though the light’s brightness isn’t the same as a three-color light, but I can see red,

The parameters are as follows: below The 3535MWAP of Nationstar Optoelectronics was selectede-d.

The forward current is the current that the LED strip lights 12v use. The working current of diodes emitting light is quite small with a range of 10mA to 45mA.

Light-emitting Diodes (LEDs) are connected in series with resistors in order to shield them from voltage spikes.

lD: is the term used to describe wavelength.

The different materials used in the die can produce different shades.

The luminescent color of the material can be changed by changing the impurities, the concentration or the composition.

The table below outlines the different luminescent materials which are used in LEDs.

Utilization of Luminous Color Materials Wavelength

Ordinary red GaP 700

High Brilliance red GaAsP

GaAlAs Super bright red

AlGaInP Super bright red, 625-640

Green normal GaP 565-572

High Brilliance Green AlGaInP 572

Super bright green InGaNg 505-540

GaAsP in normal yellow 590-610

Super bright yellow AlGaInP 590-610

Light intensity IV

The light flux generated by a lightsource within an angle unit is called the light intensity of the light source.

The unit of luminous intensity is known as candela (cd), which is commonly use-d millicandela (mcd).

A light source emitting one lumen within a solid angle of one unit is referred to as a candela. Candela is the luminous power of any light source that is located in the given direction.

VF: forward voltage

Forward voltage refers to the voltage drop created between the positive electrode and negative electrodes when the current flowing forward through the LED has defined, which is symbolized with the symbol VF.

Our company makes use of SMD LEDs with an output voltage that ranges from 2.0V up to 3.5V.

If it exceeds the operating voltage of normal the diode can be destroyed. When the forward voltage falls below a certain threshold (also called the threshold value) The current is tiny and no light is that is emitted.

When the voltage is greater than a certain level that is, the forward voltage increases quickly with the voltage and emits light.

The measured forward voltage drop is a mere few volts which means that the light emission is not correct.

View angle: perspective

In the graph of luminous intensity distribution the angle created by an intensity equal to half of the maximum intensity is termed the half value angle.

In Figure 5>.

In the image, the normal direction of the LED is that of the mechanical axis, that is the direction in which the maximum light intensity is the direction of the optical axis, and the angle between the mechanical axis and optical axis will be the angle of deviation.

The size of the chip, the overall dimensions of the packaging mold strip, the depth of the reflector cup of the bracket and the depth of insertion of the bracket in the mold cavity have a direct impact on the half value angle.

Half-value angles of various sizes can be manufactured by choosing various materials and different package sizes according to the requirements of the customer.

In accordance with the diagram of intensity distribution, there are three categories:

High directivity is achieved by using metal cavity packaging with reflective metallic or epoxy pointed packaging. This can be done without the use of a scattering agent.

The half-value angles are between 5deg and less than 20deg. It is highly direct and is able to be used as an in-place lighting source, or utilized in conjunction with a light detector to form an automated detection system.

Standard type. is usually used to indicate with the half-value angle being 20deg-45deg.

The c scattering light offers a wider viewing angle as well as a half value angle between 45deg and 90deg.
