FILN Circular Plastic Pilot Lamp Red 12V Various Equipment Indicator Lights
The 12.5 mm mounting hole of this plastic pilot lamp is a threaded mounting hole. The shell is generally white. The double white line in the picture is because of the neon bulb or LED, regardless of the positive and negative poles.
We can also make other wire colors. Generally, we use AWG22 wire. Neon bulbs can be made of 110v, 220v or 380v. Other voltages are not available. The price advantage of neon bulbs is cheap, but the quality is also very good.
The neon bulb is wired separately to the switch. When the switch is closed, the current of the neon bulb is turned on and emits a weak light. The power consumption of the neon bulb is small, but the biggest problem is that the service life is relatively short. A good neon bulb can only work 30,000 About hours, the neon bulbs of inferior quality are even less than 10,000 hours.
How to distinguish the quality of neon bulbs?
The first method:
Hold one pin of the neon bulb with your finger, and touch the tip of the soldering iron you are using to the other pin of the neon bulb. If the neon bulb can glow (not very bright), it is good.
If it is a neon bulb that has been soldered in the circuit, you can solder any pin of the neon bulb, touch the soldered pin with the tip of the soldering iron, and touch the other pin with your finger (sometimes you don’t need to touch it) , A good neon bulb will also glow.
This method is very useful when repairing home appliances. It is safe and convenient to judge the quality of neon bulbs without powering on the appliances.
The second method:
Hold one end of the neon tube with your left hand, and rub the plastic barrel with your right hand on your hair to make the barrel generate static electricity, and then the barrel will quickly primary the neon tube end.
If the neon pilot lamp and the neon tube are normal, you can see the sparkle flashing between its internal poles, and then it goes out. The brightness may not be too bright, and it is best to be in a dark place. If the neon lamp, neon tube, or neon bulb under test is faulty, it will not turn on.
If it is to test the “jumping bubble” neon bulb in the starter, the capacitor needs to be disconnected.
LED, also known as a light-emitting diode, is recognized as the mainstream of the development of lighting sources in the next 10 years. The power consumption of the small LED pilot lamp is only about 1/3 of the same illuminance, and the service life can reach more than 100,000 hours.
The current problem of LED plastic pilot lamp application in switch indication is that the cost is relatively high. At the same time, LED, as a lighting source that is not yet fully mature, has unsatisfactory performance in terms of stability.
The light source is stable. Compared with ordinary diodes, LEDs have the advantages of small size, bright colors, low power consumption, high luminous efficiency, fast response speed, vibration resistance and long service life.
It has a wide range of uses in modern society, such as lighting, flat panel displays, medical devices, etc., through the combination of electrons and holes to release energy to emit light. It is widely used in the field of lighting. Light-emitting diodes can efficiently convert electrical energy into light energy.
5 mm LED pilot lamp has low bead decay: the luminous decay of 50,000 hours is only three-thousandths, and the consistency of the product is good;
5 mm LED pilot lamp beads efficient light distribution: the unique light distribution design can make the light emitted by the chip more evenly distributed, reducing the glare and glare;
5 mm LED pilot lamp beads to have a long life: After testing, the average life of the lamp is more than 50,000 hours, and the color rendering is good: the color rendering of this series is more than 70.
1. Look at the brightness: the brightness of the LED is different, and the price is different. The LED used in the fixture should meet the laser class Ⅰ standard.
2. Test antistatic ability: LEDs with the strong antistatic ability and strong antistatic ability have a long life and high price. Generally, only LEDs with antistatic properties greater than 700V can be used for LEDs.
3. Test whether the consistency of wavelength is up to standard: LEDs with the same wavelength and wavelength have the same color. If the color is required to be consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors.
4. Test for leakage: Leakage current LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. LEDs with large leakage current have a short life and low price.
5. Look at the light-emitting angle: LEDs with different light-emitting angles have different light-emitting angles. Special lighting angle, higher price. Such as the full diffusion angle, the price is higher.
6. Evaluate the service life: The key to different qualities of life is life, and life is determined by light decay. Low light decay, long life, long life, high price.
7. Distinguish the grade of the chip: The luminous body of the chip LED is a chip, and the price of different chips is very different. Chips in Japan and the United States are more expensive. Generally, the prices of chips from Taiwan and China are lower than those in Japan and the United States.
8. Distinguish the size of the chip: the size of the chip. The size of the chip is expressed by the length of the side. The quality of the large chip LED is better than that of the small chip. The price is proportional to the size of the chip.
9. Check whether the safety performance is up to standard: The colloid of ordinary LED is usually epoxy resin, and the price of LED with anti-ultraviolet and fire retardant is more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof.
Each product will have a different design. Different designs are suitable for different purposes. The reliability of LED lighting includes electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, and safe use time. And other factors. From the perspective of electrical safety, it should comply with relevant international and national standards.
The neon bulbs and LEDs selected by Yulin Electronics are of good quality, so our pilot lamps are better sold globally. You can search for our pilot lamps on AliExpress, Alibaba and other platforms, and our pilot lamps The lamp has passed many certifications, such as UL, CE, ROHS, and IP waterproof rating certifications. Both showed good results.
