(1) LED lamps are widely used in display and communication applications due to their features such as shock resistance, fast response time, energy efficiency, and long lifespan. They are commonly found in indoor and outdoor displays, which can be categorized into full-color, three-color, and monochrome types. Traffic lights primarily use ultra-bright red, green, and yellow LEDs because they are not only energy-efficient but also durable, making them a popular choice for modern traffic signal systems. As a result, traditional signal lights are being gradually replaced by LED alternatives at an increasing pace. (2) In the automotive industry, LEDs are used in various lighting components, including dashboard indicators, switch backlights, reading lights, brake lights, tail lights, side lights, and headlights. Their compact size, reliability, and low power consumption make them ideal for both interior and exterior vehicle lighting. (3) One of the most promising applications of LEDs is in backlighting for liquid crystal displays (LCDs). High-efficiency side-emitting LEDs offer advantages such as long life, high brightness, no electromagnetic interference, and excellent cost performance. These features have led to widespread use in devices like electronic watches, mobile phones, calculators, and point-of-sale machines. With the growing trend toward smaller and more portable electronics, LED backlight technology continues to evolve toward thinner designs, lower power consumption, and better light uniformity. (4) LED light sources have also made significant progress in general lighting. Early LED products had limited luminous efficiency, with light intensity ranging from several to tens of milli-candela, making them suitable for indoor applications such as home appliances, instrumentation, communication equipment, microcomputers, and toys. Today, the main goal is to replace traditional incandescent and fluorescent lamps with LED lighting. This shift has already begun in specific application areas and is expected to expand rapidly in the future. (5) Beyond traditional uses, LEDs have found creative applications in everyday items. For example, some children's shoes feature built-in LEDs that flash when walked on, adding a fun and interactive element. LED power indicators are also used in electric toothbrushes, while LED Christmas lights are becoming increasingly popular due to their vibrant colors, durability, and safety. These lights are not easily broken and operate at low voltages, making them ideal for decorative and practical use. (6) Additionally, LED technology has expanded into niche areas such as fishing lights, where their energy efficiency and long lifespan provide reliable illumination in challenging environments. 1. Components of piston rod seal: Piston Rod Seal,Hydraulic Cylinder Rod Seal,Pneumatic Rod Seal,U Ring Seals,Hydraulic Seals DG Zhongxingshun Sealing Products Factory , https://www.zxs-seal.com
Polyurethane, polyformaldehyde, rubber
2. Purpose and function of piston rod seal:
The rod seal belongs to the dynamic seal. It is the seal that moves with the piston rod. It is one of the important components on the hydraulic support.
3. Use position of piston rod seal:
Guide sleeve, piston
4. Working principle of piston rod seal:
It is used at the contact part between the guide sleeve and the outer cylinder to seal the emulsion in the outer cylinder.
5. What effects will be caused by improper use or operation of piston rod seal:
1. Improper selection of cavity support material will wear the cavity and piston rod.
2. The size of the friction pair is inappropriate, causing wear.
3. Improper thread guide angle of cylinder barrel and piston end wear the sealing ring.
4. The seal ring is worn due to improper installation guide angle of the seal.
5. The surface of cavity and piston rod is rough, with scratches and worn seals.
6. The outer cylinder leaks and the jack does not maintain pressure.
