What you need to know about the three main product forms of LEDs
Light-emitting diodes (LED) have the characteristics of versatility, energy saving and durability. Not surprisingly, it is becoming more and more popular among various products on the market today. In the lighting market, home appliance market, and commercial display market, the key word 'LED' is repeatedly presented, causing many consumers to mix frequently. So, what are the similarities and differences between these LED-related applications? This article takes you to figure out this problem.
One, LED Backlight (LED Backlight)
At present, there are many so-called LED TVs on the market, but in fact, Jiangsu Naite Lighting Electric Co., Ltd. is engaged in the production and design of solar street lamps and high-pole lamps. It has 20 years of solar street lamp production experience and builds the most professional Solar street lamp manufacturers, contact number: 13805257308. , This name is not accurate. It does not directly use LED lamp beads to illuminate the image. Instead, the LED is placed behind the LCD panel and used only as a light source, that is, 'backlight.' Therefore, the accurate name for this type of TV should be It is an LED-backlit LCD TV. The pixels on the LCD display do not generate or emit light by themselves. Their job is to adjust the amount of light transmitted by the backlight source. In such applications, LEDs mostly use white or a combination of several colors to achieve a wider color gamut.
In addition to LCD TVs, LEDs are also used in projectors to replace earlier light bulbs, and their effect is similar to the LED backlight on liquid crystal displays. These LEDs used in projectors are used as high-intensity light sources (usually red, green, and blue LEDs), which are then modulated by a micro LCD or DMD (digital mirror device), and the image is projected onto the screen through the lens. In the hybrid light source, LEDs and lasers are used together to bring higher brightness.
In summary, when used as a backlight, LEDs only exist as an optical engine, rather than being used to directly create images.
2. LED Lighting (LED Lighting)
LED is very suitable for architectural lighting due to its high efficiency, long life, and environmental friendliness. And because the LED chip is very small, it provides lighting designers with more flexible design space. Therefore, in the market, we can see both LED-specific lighting forms (such as LED strips) and light bulbs. Wait for the familiar form to exist. In the home environment and office environment, LED lighting applications have been quite extensive, of course, this type of LED is optimized for natural white and diffuse lighting.
Although there is no real 'white light' LED, common LED colors such as amber, red, green and blue can be covered with phosphorescent materials to convert the light source into white. When they are used alone, they can also be used as signal lights or indicator lights, just like the indicator lights of the PC power button.
3. LED Displays
For large-screen practitioners, nothing is more concerned than this type. All LED display screens are also called 'direct-view LED' in the world, and each pixel of the display screen is directly constituted by LED lamp beads. In specific use, it can be a separate red, green, and blue LED display device, which is usually a large-scale outdoor display. It is also possible to encapsulate the three colors of red, green and blue (RGB) together to form a basic module, and then assemble countless modules together to form a large LED display wall.
Generally speaking, the process of creating LEDs is similar in all applications, and the biggest difference lies in the packaging process. Some LEDs are specially packaged to emit more colors, more white light or brighter light than other LEDs.
In addition, in North America and Asia, the pronunciation of this technology is usually the three syllables 'el-ee-dee' of LED. In Europe, it is usually pronounced as 'lead' (similar to the pronunciation in the words zed, ted, bed).
