Two Color LED Indicator Light Detailed Parameters

What is the red-green two color LED indicator light?

Light emitting diodes are called LED for short. It is made from gallium, arsenic, phosphorus, nitrogen, and other compounds.

When electrons combine with holes, they emit visible light, which can be used to make light-emitting diodes. Used as an indicator light in circuits and instruments, or as a text or digital display. Gallium arsenide diode red light, gallium phosphate diode green light, silicon carbide diode yellow light, gallium nitride diode blue light. Therefore, the chemical properties of organic light-emitting diode LED and inorganic light-emitting diode LED.

The red green two color LED indicator light is an indicator that can switch between two kinds of light.

Two color LED with three pin. This indicator has three pin, the middle foot is a common pole, one side is straight and the other is diagonal, which corresponds to one color.

Take the example of red and green. Generally, the straight pin corresponds to red, and the slanted pin corresponds to green. When the current flows from the middle pin to the straight pin, the red light works.

When the current flows from the middle pin to the slanting pin, the green light works.

When the current flows from the middle pin to both pin, the red and green lights work together, mixing into colors.

The general circuit will choose the red and green of this two-color LED to indicator the two working states of the circuit.

In addition, there is a third mixed color, but the consistency of this mixed color is more difficult to control.

What is the product details of the red green two color indicator light?

• The mounting dimension of the two color LED indicator light is 8mm, which is a popular product in our company.
• The product can be achieved to a variety of colors, such as red and green, red and blue, blue and green, and other two colors. You can send us your needs and quantity, we will provide a plan for your reference.
• Generally, the voltage of these two color LED indicator lights can be 3~380v, but generally12V, 24V, 220V is more conventional.
• The waterproof rating of the red green two color LED indicator light is IP67, which can be used outdoors.

It can be used in drinking fountains, coffee machines, water heaters, subway indicator lights, power chargers and other equipment.

The reason why the two color LED indicator light emits two colors is that we use two chips, both of which are packaged in the same bracket.

How does the two color LED indicator light control its luminous color?

Generally, it is a two color LED indicator light with three pins and a two-color light with two pins.

The three-pin and two-color lamp also has a common yin and a common yang. The length of the three pins is different. The difference between the common yin and the yang is mainly based on the positive and negative poles, of which the longest pin is in the middle.

If the middle pin is positive, it is common yang. If it is the negative electrode, it is the common negative.

Electric current generally flows in from the positive electrode and flows out from the negative electrode.

Two-pin non-polar and two color LED indicator light, which is to encapsulate two color chips in one LED. Of course, the two chips must be connected in parallel with opposite polarities. In this case, the positive and negative poles of the power supply at both ends are added.

The two-color control can be realized by the difference. In fact, it should be three-color. If you add AC, it will be another color. The forward power will emit one light, and the reverse power will emit another light.

For example: according to the red and green two-color LED , mark its two pins as A and B. If the voltage you apply to is A positive and B negative, it will light up in red, and in turn you give it If the applied voltage is B positive and A negative, it will be bright green.

In fact, this LED has another color, that is, it can be combined into yellow when it is on at the same time. Two-color lights can be used as indicator lights on power supplies and chargers. Most of the power supplies use red and green (common green) dual-color lights. They can also be used on subways to indicate stations (from red to green, and green turns red).

Signal Lamps，The Ultimate Guide

What is the meaning of the three wires of the red green two color LED indicator light?

The two-color LED indicator light we currently produce has three lines, such as red and green two color LED indicator light, it has three lines, one line is common cathode or common anode, generally black, and the other two lines correspond to the color of the light.

We will use red wires for red and green wires for green lights. The length of the wire is 20cm, and the wire is AWG22 or AWG24. It depends on your specific requirements.

How to connect the wire with the red green two color LED indicator light?

The three lines on the indicator light are all different colors, the red line represents a red diode and the green line represents a green diode. We are based on the actual use of the equipment, connect different lines to the set lines, which means complete the wiring work.

Two-color lamp beads have 3 pins, as you can see from the graph. When the switch S1 is closed, a current flows through the green tube of the two-color luminous lamp beads, so the two-color luminous lamp beads emit green light.

When the switch S2 is closed, the current passes through the internal red tube of the two-color light beads, thus emitting red. If both switches are switched on at the same time, the current flows through both LEDs at the same time.

The red and green lights up at the same time, and what we can see is a mixed color light, which becomes yellow.
