LMR4-1000 module using Cree TrueWhite ® technology, enabling higher quality and the illumination light efficiency, compared with the 26-watt compact fluorescent lamp (the CFL), 42% of the input power is dropped. In addition, the LMR4-1000 is the industry's only commercial 2700 K LED module that achieves 1000 lumens of light output with a color rendering index (CRI) greater than 90. It can be used to replace 100 watt incandescent in downlight applications. light bulb.
Scott Schwab, product line manager of Cree LED modules, pointed out: "LMR4-1000 can help customers quickly and easily bring beautiful and energy-saving LED lighting to the market through technical verification. LMR4-1000 is built on Cree LED module series. On the basis of success, it can fully meet the high-quality lighting needs of applications in restaurants, hotels and homes, further promoting Cree's innovation in the LED lighting market and bringing easy and integrated solutions to the market."
The Cree LED module LMR4-1000 is highly integrated with drive, optics and thermal management technologies, enabling the compact and compact Cree module to be plug-and-play. The LMR4-1000 module has been designed with a lifetime of up to 35,000 hours and a 5% dimming range, and offers over 90 Color Rendering Index (CRI) for 2700 K, 3000 K, 3500 K and 4000 K color temperatures.
A port is an interface through which data is transferred between a computer and other devices (such as printers, mice, keyboards or monitors), networks, or other directly connected computers.
For the CPU, the port is used as one or more memory addresses for sending or receiving data. Dedicated hardware, such as an additional circuit board, places the data from the device in a memory address, and sends the data from the memory address to the device. Ports can be dedicated for input and output only. The port usually receives a specific type of plug for a specific purpose. For example, serial data interfaces, keyboards, and high-speed network ports all use different connectors, so it is impossible to plug the cable into the wrong port.
In programming, a port is a "logical connection location", especially in the Internet Protocol TCP/IP, a way for the client program to be assigned to a special service program on the computer. High-level applications that use TCP/IP protocols such as web protocol and hypertext transfer protocol have specially designated ports. From the perspective of port allocation, ports are divided into two categories: fixed ports and dynamic ports: Fixed ports (0~1023): use a centralized management mechanism, that is, subject to the assignment of ports by a management organization, which is responsible for issuing these assignments . Because these ports are closely tied to some services, we will often scan these ports to determine whether the other party has enabled these services, such as TCP 21 (ftp), 80 (http), 139 (netbios), UDP 7 (echo), 69 (tftp) and other well-known ports; Dynamic ports (1024~49151): These ports are not fixedly bound to a certain service. The operating system dynamically allocates these ports to each process, and the same process is allocated twice It is possible to assign to different ports. However, some applications are reluctant to use the dynamic ports allocated by the operating system. They have their own "branded" ports, such as port 4000 of the oicq client and port 7626 of the Trojan Binghe, which are all fixed and famous.
