Basic Knowledge Of Indicator Light—-You Must Know
In electrical equipment and even household appliances, indicator lights are very common. Today, I will introduce you to some basic knowledge of the indicator lights, I hope you can gain something.

1. Size And Usefulness
The English name of the indicator light usually has indicator lights, indicator lights, signal lights, signal lights, indicator lights, and indicator lights. It is installed on the panels of various machines and equipment and is used to indicate the related lighting and light signals, prompt the technical status of the operating system, and issue an alarm light signal under abnormal conditions.
The indicator lights have metal indicator lights and plastic indicator lights. The Mounting hole diameter of metal indicator lights have 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 19mm.22mm, as the picture shows:
And the Mounting hole diameter of plastic indicator lights have 6mm, 8mm, 10mm, 12mm, 12.5mm, 14mm, 16mm, 22mm,as the picture shows:
The indicator light has a wide range of uses and can be used on power distribution cabinets, like this:
Coffee machines, like this:
Lighting, kitchen equipment and other equipment panels, like this:
Our indicator light can be used for DC and AC. The general output voltage of DC is 3v, 6v, 9v, 12v, and the general output voltage of AC is 220v and 380v.
Here, I will tell you about AC/DC expansion knowledge. What is the difference between AC and DC?
I. The meanings are different: AC is the abbreviation of the AC power supply, and DC is the abbreviation of DC power supply.
II. The direction of the current is different: the alternating current flows out in two directions and then back. The size is constantly changing (the law of lighting power change is sinusoidal). The frequency can indicate the speed of the alternating current direction change, and the phase can indicate the starting time of the AC power transmission. Direct current has only one direction, that is, current can only flow from the positive electrode to the negative electrode.
III. Different uses: Our common electric lights, motors, etc. are all AC; DC is mainly used in various electronic instruments, electrolysis, electroplating, DC power drag and other aspects.
IV. The output voltage is different: DC refers to the DC power supply. Generally, there are several common voltages such as 30V, 6.0V, 90V, and 12V, and the AC output voltage is 220V and 380V.
A complete indicator usually consists of a structure: waterproof ring, copper, nut, plum blossom washer, led lamp bead, resistor, heat shrinkable tube, base, wire, rectifier, solder, etc. So wanting to make an indicator light is a matter of patience, because every part must be at least in the right place. There are some very small parts that require special tools to complete. A complete indicator light requires patience.
As we know, indicator lights have metal and plastic, and metal indicator light has a copper and stainless steel. But what I want to talk about next is the very important part of the indicator light, the lamp bead. The lamp bead of indicator light has led type and neon bulb. The led lamp bead:
And Neon bulb has two types
Generally, we will use the best quality lamp beads, except for customer requirements
Let me give you some other characteristics of the popular science indicators, which vary from company to company. Take our company as an example. First, for the base material. If it is a conventional type, the indicator light is more environmentally friendly and does not withstand high temperatures, usually withstanding temperatures below 90 degrees Celsius.If it is specially customized, it is usually not environmentally friendly, but it is resistant to high temperatures and the temperature is generally less than 150 seconds. second. About withstand voltage test. If it is a metal indicator, its pressure resistance is generally 1700v, if it is plastic, its pressure resistance will be a little higher than that of the metal indicator light, and its pressure resistance is 2000v.
And now, I will introduce you to a wire-type and a pin-type indicator lights. As you can see, this type is with wire and this type is with pins.
But according to the installation method, the indicator light has been embedded and threaded. This is embedded.
And this is threaded.
Next, I will introduce to you the customization service of indicator light. We provide special symbol customization, or you can send the symbol you want and we will make it again. These are some symbol of our company.
A qualification certificate is a very important thing, you must ask a certificate of indicator light to purchase the indicator light.
In addition, our company indicator light has over 20 years of history, and now has UL, CE and other certificates. You can trust our quality.
6. Best-selling product
In the end, I will introduce you to our company’s hot products. Its mounting hole diameter is 8mm, and it has two colors, like this. At the same time, it also has a waterproof function and can be used normally in water. This waterproof indicator light is our company’s best-selling product. It is very popular in Europe, America and Asia, and many customers will buy it again.
Finally, I hope that readers can have some understanding of the indicator lights, and if you are interested in our company’s indicator lights, please contact our staff……
