The launch of Avago high power infrared transmitter series products

The luminous intensity of 5mm LED is as high as 200 mW/sr, which shows the advantages of high speed, low forward voltage and low cost in consumer electronics and industrial applications. The luminous intensity of 5mm LED is as high as 200 mW/sr, which shows the advantages of high speed, low forward voltage and low cost in consumer electronics and industrial applications. Infrared transmitter Avago Technologies (Annwa Technology) recently announced the introduction of a series of high power infrared (IR, Infrared) LED transmitter using 5mm (T-1 3/4) in line package 870nm and. These new infrared emitters using Avago Technologies high power AlGaAs (AlGaAs) LED technology, with excellent high luminous intensity, high speed and low forward voltage characteristics. The new product packaging size of 5mm, the use of iron wire frame, in a variety of current environment can be efficient heat dissipation. Avago Technologies of the HSDL-42xx series infrared transmitter is especially suitable for consumer electronics, industrial and communications infrared transceiver for longer distance connections and more high-speed data transmission technology has the specific needs of the field, the main applications include access control, portable instrument, infrared optical mouse, smoke detectors, infrared LAN (IR LAN) and audio transceiver signal connection. 870nm wavelength products are usually used in the field of infrared communications, while 940nm is mainly used in the field of remote control. Avago Technologies and China Hongkong area general manager Mr. Li Ting said: "at present, the infrared transmitter manufacturers in favor of high power, low forward voltage and high speed, to meet various applications of the growing connection distance and data transmission rate requirements. Avago Technologies the latest infrared transmitter products to our customers a surprise." The peak value of Avago HSDL-4250 and HSDL-4251 is 870nm, and the forward voltage is only 1.4V under 20mA current, and the time of optical reaction is 40ns Technologies. In the forward current of 100mA, the luminous intensity of the HSDL-4250 axis is 180 mW/sr, and the visual angle is about 15 degrees, while the visual angle of HSDL-4251 is about, and the luminous intensity of 100mA is 100 mW/sr. Avago Technologies HSDL-4260 peak is 875nm, luminous intensity standard axis in 100mA current under the condition of 200 mW/sr, a visual angle of 15 degrees, the optical response lifting time is 15ns, the forward voltage at 20 mA for 1.4V. The peak value of Avago HSDL-4270 and HSDL-4271 is 940nm, the forward voltage is at 1.3V 20, and the optical response time is up to 1.3 mA. The axial luminous intensity of the HSDL-4270 is 100 mW/sr, with a viewing angle of about 15 degrees, while the HSDL-4271 provides a brightness of 30 degrees and a luminous intensity of 50 mW/sr.
