Cree introduces lighting-grade LEDs that eliminate the cost of upfront systems

Abstract: Cree recently announced the introduction of breakthrough XLamp® XB-D LEDs to accelerate the adoption of the next generation of mainstream LED lighting. This LED can further simplify the design and fundamentally eliminate the key obstacles that limit the popularity of LED - the cost of the pre-system.

Cree recently announced the introduction of breakthrough XLamp® XB-D LEDs to accelerate the adoption of the next generation of mainstream LED lighting. The XLamp® XB-D LED is the first LED to use the latest Cree innovation technology platform to bring lighting-grade LEDs to a new era of cost-effectiveness. This LED can further simplify the design and fundamentally eliminate the key obstacles that limit the popularity of LED - the cost of the pre-system.

Cool White XLamp® XB-D LED

Cree XLamp® XB-D LeDs are twice as cost-effective as other LED products and come in the industry's smallest 2.45 mm x 2.45 mm lighting-grade package, which is 48% smaller than XLamp® XP LEDs and meets the need for high lumens Density and compact light sources for lighting applications. The new generation of lighting-grade LEDs adopts new and innovative technologies that can reduce the number of LEDs and optical components used in the traditional design by one-third, and can significantly reduce the board size, which can significantly reduce costs.

Warm white XLamp® XB-D LED

According to Mike Watson, Cree's senior marketing director of LED components, "As an industry leader, Cree will promote LED lighting revolution with breakthrough innovations. With this new platform, Cree has fundamentally redefined its customers. The new benchmark for cost-effectiveness is simply to increase the brightness of LEDs, but it is also necessary to increase the investment return and market acceptance of LED lighting products."

The XLamp® XB-D LED uses Creety's proven silicon carbide technology. At a current of 350 mA driving current and a temperature of 85°C, the luminous flux and luminous efficiency of cool white (6000K) XB-D LED are 139 lm and 136 lm/W, respectively. The luminous flux and luminous efficacy of warm white light (3000K) XB-D LED are respectively 107 lm and 105 lm/W. The XB-D LED is compatible with the most widely used XP Series secondary optics to speed up the optical design process and directly reduce the cost of existing XP Series designs.

USB 2.0 Hubs

USB 2.0 is a USB interface standard released in 2000 with a theoretical maximum transmission speed of 480Mbps (about 60MB/s). The port has four cables (five cables for MicroUSB and MiniUSB), and the maximum output current is 0.5A. USB 2.0 is currently the most common version of USB port, almost all computers have USB 2.0 port, most USB devices also support USB 2.0. USB 2.0 hub. The device can provide USB high speed or full speed connection on the uplink port. The device also provides USB high-speed, full-speed, or low-speed connections on the downlink port. When the uplink port is connected to an electrical environment that supports only high-speed, full-speed, and low-speed connections, the high-speed, full-speed, and low-speed USB connections on the downlink port are enabled. When the uplink port is connected to an electrical environment that supports only full or low speed connections, the USB high-speed connection on the downlink port is disabled. USB 3.0 Hubs is higher than usb 2.0 in terms of transmitting data.
