OSRAM Opto Semiconductors has developed the smallest RGB MultiChipLED. This product is especially suitable for large-size, high-resolution, full-color screens, ensuring that the picture is still close at a close angle. Because this component is very compact, it can accommodate a large number of pixels even in a small screen area. Installed in a black package, this LED provides virtually no ambient light and delivers contrast-rich, colorful light.
The latest RGB product from OSRAM Opto Semiconductors is available in a compact package measuring only 1.6 mm x 1.6 mm and a height of only 0.9 mm. The pixel pitch of this LED can be as small as 2 mm, so even a very small screen can be used. Hold a large number of pixels. For example, a screen area of ​​less than 10 m2 is enough to hold more than two million pixels to display a high-definition TV picture. A 2.5x 4.0 m screen can achieve a system brightness of 1500-2500 cd/m2, which is about ten times the brightness of a normal LCD TFT screen.
Thanks to specially developed packaging materials, this product has perfect color mixing performance. From any angle, the color appearance can be kept constant, even when viewed from the side, the picture is still vivid. Since the LED is mounted in a black package, it will hardly reflect any ambient light, so the picture quality will not be affected.
The Multi ChipLED is packaged in a red, blue and yellow chip made of Thinfilm and ThinGaN. At 20 mA operating current, the typical illuminance of each chip in the RGB LED is 250 mcd (red), 350 mcd (green), and 70 mcd (blue). The typical efficiency of this luminous intensity is 4 cd/W, which is equivalent to a luminous efficiency of 12 lm/W. The LED has a beam angle of +/- 60°.
Multi ChipLED enables high-resolution, full-color screens in TV studios, modern conference rooms, concert halls, and trade fairs to present colorful, high-contrast images that give viewers a full range of visual enjoyment.
An Outdoor CPE (Customer Premises Equipment) is a client device used in outdoor environments, typically for wireless network connectivity. It is a device used to transmit Internet signals from a service provider to the user's location.
Outdoor CPE is commonly used to provide broadband access services, especially in remote areas or places without traditional wired network coverage. It can transmit an Internet connection via wireless signals to the building or area where the user is located. Outdoor CPE is typically a highly protected and durable device designed to handle harsh weather conditions in an outdoor environment.
Outdoor Cpes typically include the following main components:
1. Antenna: Outdoor CPE is usually equipped with a high-gain antenna for receiving and sending wireless signals. These antennas can be designed for different frequency bands and wireless standards.
2. Wireless module: Outdoor CPE usually includes a wireless module to handle the transmission and reception of wireless signals. This module usually supports different wireless standards such as Wi-Fi, LTE, 4G, etc.
3. Router function: Outdoor CPE usually has the function of a router, which can distribute the Internet connection to the device where the user is. It can provide IP address allocation, port forwarding, network security and other functions in the local area network.
4. Power supply and battery: Since Outdoor CPE is usually used in outdoor environments, it usually requires a reliable power supply. Some Outdoor Cpes are also equipped with batteries to provide continuous Internet connectivity in the event of a power outage.
The main features and advantages of Outdoor CPE are as follows:
1. High-speed broadband access: Outdoor CPE can provide high-speed broadband access services through wireless signals, so that users can enjoy high-speed Internet connections in places without traditional wired network coverage.
2. Flexibility: Since Outdoor CPE is a wireless connection, it can be used in different locations and environments. Users can place the Outdoor CPE in the best position as needed for optimal signal coverage and performance.
3. Simple installation: Outdoor CPE usually has a simple installation process, and users only need to place the device outdoors and make some basic Settings to start using the Internet connection.
4. Strong anti-interference ability: Outdoor CPE usually has strong anti-interference ability and can provide stable Internet connection under harsh environmental conditions. It can cope with various sources of interference, such as electromagnetic interference, weather conditions and so on.
5. High reliability: Outdoor CPE usually has a high degree of reliability and durability, and can be operated for a long time in a variety of outdoor environments. It usually has waterproof, dustproof, lightning-proof and other functions to cope with different weather conditions.
Outdoor CPE is widely used in a variety of scenarios, especially in rural areas, mountains, islands and other places without traditional cable network coverage. It can provide high-speed broadband access services to residents and enterprises in these areas, helping them to enjoy the convenience of the Internet.
In summary, the Outdoor CPE is a client device for outdoor environments to provide high-speed broadband access services via wireless signals. It is highly reliable, flexible and anti-jamming, and can provide a stable Internet connection in a variety of outdoor environments. It plays an important role in providing broadband access services, especially in places without traditional wired network coverage.
