Infra-Red Sensor Technology Corp. has carved out a niche in the lighting market with its patented infra-red sensor system, originally developed for security systems. The company presented the device, which it calls the "Digital Passive Infra Red Module," three years ago. When used on lamps, the sensor module activates bulbs/tubes when movement is detected.

The module is unique in that it can be used on fluorescent as well as incandescent lamps. "Analog-type sensor systems are not able to activate the starters on fluorescent lamps, though they perform well with incandescent lamps," says company general manager Hsing Yen-hua.

The digital controllers used also have advantages over analog devices, including greater power efficiency. "Most analog models consume 50 to 100 milliamperes in standby mode, while our digital sensors use only five to 10 Ma," says Hsing. The technology used in the digital sensor was developed in line with the knowledge accumulated in the company's decade of experience in the security-sensor business.

Big Performance in a Little Package

By using digital technology, Infra Red Sensor can cram all of the devices and circuits on a module measuring 4cm x 4cm. The module board controls a light's on and off functions with two circuits. Analog models use three circuits and are built with larger devices, making them too big for some lighting systems.

The module board also features a micro- adjustment controller with nine switches to adjust, when the sensor is activated, the degree of luminance and sensor sensitivity.

The sensor has a maximum detection distance of 15 meters and sensing angle of 160 degrees. Hsing says that most other systems have a maximum angle of 140 degrees. Sensing probes can be set for five-second, 30-second, one-minute, three-minute, five-minute, and 15- minute intervals.

While Infra-Red Sensor developed the modules for security systems, it has recently begun supplying the innovative devices to several lighting manufacturers. The company has invested in a factory in Ningbo, mainland China to make the sensors for outdoor lamps destined for overseas markets. Its head factory in Taiwan handles design and production of the devices for indoor lamps and security lamps sold in Taiwan. Exports from the mainland and domestic sales in Taiwan currently account for 80% and 20% of the company's revenue, respectively.

Australia and Belgium have been among the company's primary overseas markets since it began shipping the devices in 2001. Recently, Infra Red reports, it has received many inquiries from Japanese and east European suppliers. The company has not yet explored the U.S. market due to the intense competition there, Hsing says.

Growth Business

The new device is projected to boost the company's lighting-related revenue by 15% annually over the next few years, according to Hsing. Security sensors currently contribute the bulk of company revenue, with lighting products accounting for only 5%, or NT$90 million (US$2.6 million at US$1:NT$35), according to company chairman Jerry Chen.

Infra Red Sensor is now Taiwan's No. 1 supplier of infrared security-sensor systems, according to Hsing. "We are contracted by the Taipei City Government to supply 70% of the sensor systems used to light up Taipei streets and facilities to improve safety," he reports. The company also states that it supplies around 60% of the security sensors used by the neighboring Taipei County Government.

Security guards and police can identify objects detected by the company's sensor systems from monitors in their offices. When objects enter the system's sensing range, spot lamps connected to the infrared sensor are automatically activated.

To cope with heavy demand in Taiwan, Infra- Red Sensor has opened branches in central and southern Taiwan and contracted 300 stores to sell its products.

Hsing sees a shining future for his company's new digital device, especially with concern for the saving of energy on the increase around the globe and the spreading use of sensor systems in new buildings. At the same time, however, he expects strong competition in overseas markets, and will continue striving to find his place in the spotlight by burnishing its quality and brand image to distinguish its products from low-margin rivals.
