In the 2015 Taiwan International Lighting Technology Exhibition, the LED epitaxial faucet factory Jingdian has realized the infinite possibilities of LED as the core concept. In addition to continuing the high-voltage chip and flip chip (PEC) that was promoted last year, it also shared the success of collaborative development with customers for the first time. Case. Jingdian is one of the few manufacturers of full-band LED chips in the world. Among them, infrared light (IR) has been the field of long-term cultivation of crystal power. With the great progress of infrared LED performance, Jingdian has also actively explored many emerging applications. Jingdian has a complete infrared LED product, and its performance has also been greatly improved. From the perspective of photoelectric conversion efficiency, the conventional tungsten filament bulb is less than 10, the energy-saving bulb and the fluorescent lamp are about 30, and the white LED is about 50. The IR850nm product released by Crystal Power last year has a maximum photoelectric conversion efficiency of 75.29 at a laboratory operating current of 40 mA, while still maintaining 70 outputs at 350 mA. In the brightness part, the IR850nm product has a brightness representative value of about 190-220mW before packaging, and the brightness after packaging can be increased to 1.5 times. Epistars are about to increase in brightness by 15-20 per year. There are many competitive products on the market, but only brightness, crystal power is the leader's role to provide manufacturers solutions. Infrared LED application has broad potential for future medical applications. Infrared LEDs are widely used. In addition to small-sized applications such as remote controls, earphones, microphones, and mobile phone inlet switches, Jingdian is also actively targeting security products, medical and biotechnology. High value-added application market efforts. Chen Xingang, director of the product management group of the Crystal Power Marketing Center, said that the traditional security lens is covered with at least 30-40, or even more than 100 infrared LED bulbs, depending on the product specifications, but with the security lens resolution Continuous improvement, infrared LEDs also need to be brighter, customers began to introduce high-power design, and the high-power infrared LED developed by Jingdian can greatly simplify the use of infrared LED bulbs on the lens, due to the reduction of LED numbers, circuit design and heat treatment It is also relatively simple. In the future, the trend of high-power infrared LEDs gradually replacing traditional Lamp packaging products is more obvious. The potential of infrared LEDs in medical and biotechnology applications should not be underestimated. Director Chen pointed out that through different LED and multi-wavelength combinations, it is expected to develop non-invasive blood glucose measurement methods in the future, albeit with poor accuracy. Can be used for basic testing, which can reduce unnecessary pain. In addition, infrared light combined with color and depth image, and further through the signal amplification algorithm, different from the previous contact measurement method, in the future only need ordinary photographic lens to detect pulse and heartbeat, greatly increasing the convenience of use. Putting together the blueprint for the future! The key factor of infrared LED application into smart home With the advent of the aging society, how to easily grasp the safety of the elderly and children is one of the irreversible trends in the future. Different from traditional architectural design, modern people are pursuing the concept of smart home, and infrared LED application plays an important role in it. Through infrared LED combined with sensing technology and data transmission, the house can actively detect and respond to people. The need to achieve home security, health care, life entertainment and other functions through automation control, greatly improve the quality and safety of future home life, and help people have a better life experience.
