Origin
Sliding doors have their roots in ancient China and were later introduced to North Korea and Japan through cultural exchanges. While the exact time of origin is not clearly documented, there are historical references and depictions found in traditional Chinese paintings. For instance, Song Dynasty landscape paintings show the presence of sliding doors, suggesting their early use in residential settings.
According to architectural records from the Song Dynasty, such as the "Yingzao Fashi" (Building Code), sliding doors were referred to as "lattice doors." These early designs featured intricate wooden lattices, which were both functional and decorative, reflecting the aesthetic values of the time.
Concept
Originally, sliding doors were primarily used for bedroom or closet entrances. However, with advancements in technology and the development of new materials and design techniques, sliding doors have evolved significantly. From simple wooden panels to modern glass, fabric, rattan, and aluminum, they now come in various forms—sliding, folding, and partition doors. This evolution has expanded their functionality and made them suitable for a wide range of spaces, including living rooms, bookcases, storage areas, and even commercial showrooms.
Characteristic
Whether it's a small square bathroom or an oddly shaped storage area, sliding doors offer a space-saving solution. By replacing traditional hinged doors, they help maximize limited spaces. Some models, like folding sliding doors, can open fully without taking up any extra room. This makes them ideal for modern homes where efficiency and aesthetics go hand in hand.
From a usability perspective, sliding doors provide excellent spatial flexibility. Their smooth sliding mechanism allows for easy movement and efficient use of space, aligning well with the fast-paced lifestyle of today. Additionally, glass sliding doors add a sense of openness and lightness to a room, making the space feel more inviting and airy. They can also be used to create subtle partitions, offering privacy without blocking the view.
In contemporary design, sliding doors are not just practical—they are also a stylish choice. For example, a sleek, transparent sliding door on a balcony can bring the outside in, allowing natural light and scenery to flow freely into the home. This makes them a perfect fit for those who value both function and beauty in their living environment.
3014 SMD IR LED supplier from China.
3014 SMD IR LED is used in LED infrared light guide plate and LED infrared backlight screen because of the small size of the product.
We produce and sell 3014 SMD IR LED, which is with the wavelength from 680nm-1550nm. In this category, we mainly introduce the two kinds of wavelengths: 940nm IR LED and 850nm IR LED. These two wavelengths are the most commonly used wavelengths in infrared monitoring. They all can be used to monitor products.
940nm infrared LEDs are totally invisible to the naked eye, which means you can't see whether the 940nm working or not. Unless you watch it through some device(like phone's camera), which will show some purple or white color light.
The 850nm infrared LEDs have a very slight reddish when it's working, which means you can see if the 850nm LED is working.
Under the same power, radiation intensity of 850nm will be higher than the 940nm. Of course, 940nm also has its own unique advantages. It is the naked eye that is indistinguishable from work or from work, therefore, its application has been widely used in many special markets in the modern era.
We supply the 3014 940nm SMD IR LED and 3014 850nm SMD IR LED products with difference power, such as: 0.1W 940nm, 0.2w 940nm, 0.3w 940nm, 0.4w 940nm, 0.1W 850nm, 0.2w 850nm, 0.3w 850nm, 0.4w 850nm and so on.
