Semiconductor laser is also known as laser diode, which uses semiconductor materials as laser’s operation materials. When comparing with other lasers, laser diode has incomparable performances, such as low driving voltage, high efficiency and safe incentive mode, so that it can be widely used for long-distance communication, digital signal storage and recovery, laser range holographic application, etc.(more)

As a fourth-generation automobile light source, LED (Light Emitting Diode) lamps have been widely used for producing many beautiful car style by car manufacturers. LED light has many advantages including no delay, energy saving, long life, low heat, seismic resistance and high color purity and it has taken place of tungsten filament lamps and halogen lamps in many fields. Although its cost is very high, LED lamp has incomparable advantages of good quality and high grade when comparing with incandescent lamp. Because of the monochromaticity of LED light, it can directly select LED components of different wavelengths to design cornering lights, brake lights, backing lights, bicycle taillight and other lights. It can also make light transmittance increase without color filters and improve the utilization rate of the light.(more)

In 1821, Thomas Seebeck discovered when two conductors with different materials and different temperature are connected, there is current flowing in the loop However, twelve years later, J. C. Peltier discovered an opposite phenomenon, that is ,by deleting a conductor in the loop, the external current can flow through the loop, and then a temperature difference between two connecting points is appeared. This phenomenon came to be known as Peltier Effect. Owing to the limitation of material at that time, the temperature difference in Petier Effect is mostly the thermal resistance produced when large current flows through the materail. Along with the development of material science in recent years, the heating or cooling effect of the connection point becomes more practical, which can be used as heat pumps. In actual application, there's no much difference with the cooling method that is based on fluorine carbon vapor compression refrigeration. There are no moving parts and working fluid in TEC, so it makes refrigeration equipment miniaturization possible.(more)

TEG is the abbreviation of thermoelectric generator, which can convert heat directly into electricity, totally opposite to TEC. TEG can be used as anti-corrosion protection for oil pipeline and gas pipeline and it can also be used as a power supply for monitoring facilities.(more)

The ATH100KL2A is a capped ntc thermistor encapsulated with glass and packaged in a compact ring lug. This thermistor series consist of ATH100KL2A, ATH100KL2AT63 and ATH100KL2AT63S. The ATH100KL2A has two leads coated with copper, the ATH100KL2AT63S has the two leads covered with plastic tubing and sealed by epoxy for insulation and liquid resistant, while the ATH100KL2AT63 is the non-sealed version. ATH100KL2A series thermistors feature better long term stability, higher reliability and wider temperature range when compared with conventional thermistor assemblies containing epoxy encapsulated thermistors inside.(more)

The ATH10KL2C is a thermistor assembly with a ring lug outside the glass encapsulated ntc thermistor. The ATH10KL2C series thermistor consists of three types, ATH10KL2C, ATH10KL2CT70 and ATH10KL2CT70S. The ATH10KL2C comes with two leads coated with copper, the ATH10KL2CT70 has the copper leads with high temperature plastic tubing and also sealed by epoxy, while the ATH10KL2CT70S is the sealed version of ATH10KL2CT70. The different types are applied to different applications. The sealed version is liquid resistant, so it can be used in the applications with some noncorrosive liquid.(more)

With the development of technology and science, thermal electric coolers (TECs) have been more and more popular in cooling system. TECs can cool and heat in the same time, depending on the direction of the input current. TECs have many advantages of no moving parts, no noise, no pollution and long service lifetime. These are the reason why TECs have been widely used in cooling system.(more)

Similar to ATH10KL2A and ATH10KL2C, ATH10KL2B is also a ntc thermistor assembly packaged in a ring lug. The inner ntc thermistor head is ATH10K1R25, thus, they have similar characteristics, while ATH10KL2B is for easy mounting.(more)

NTC thermistors are more and more popular in many applications that need temperature control or measurement. ATI released several series of ntc thermistors including ATH10KR8B, ATH10KL2A, ATH10K1R25 and ATH100KR8 series. ATH100KR8 series ntc thermistors are mainly introduced here.(more)

LED lighting is also called solid state lighting as the third generation lighting technology after the incandescent lamp and fluorescent lamp. LED lighting featuresenergy saving, environmental protection and high reliability. Nowadays, LED lighting has been widely used in daily life. Our company (ATI) has released a solarLED desk lamp, as shown in Figure 1.The LED lamp comes with eighteen LEDs, white light. The power is only 1.8 watt. The brightness is the same as a 15-watt incandescent lamp.(more)
