Introduction of LTST-M670KFKT

LTST-M670KFKT indicates the usage of LED Lighting with a wide range of applications. It is a surface mount product integrated in the market by Lite-On, offering brighter LED comparable to T-8 fluorescent lamps, great thermal design and narrow LED angle in order to form a mid-power LED array; as a result, MAXIMUM output of 5,000 lumen is achieved.

Application Field of LTST-M670KFKT

Due to its advanced design benefits, LTST-M670KFKT is widely applied in various application fields, such as Automotive Lights, Industrial Lighting, Spot Lights, Street Lights and so on. First of all, LTST-M670KFKT is especially applicable in automotive lighting, as it provides wide angle lighting, easy installation and better concentration of light without glares. Secondly, in industrial lighting, it performs occupational safety via effective and uniform lighting. Also, its narrow LED angle produces high power combined illumination to lights up the workplace precisely. Moreover, this product has great potential to be used for Spot lights, taking advantages of compact size and long life time, in order to create soft and comfortable lighting atmosphere. Furthermore, it can be utilized for Street Lights, since its broad color gamut provides reliable illumination and sweet visual experience in harsh and extreme environment.

Working Principle of LTST-M670KFKT

LTST-M670KFKT relies on the continuous current regulation of a single stage effect for its working principle. In the traditional regulations, four few cascades are usually required to reach the desired stable output, however, the LTSM-M670KFKT only needs one stage effect and thereby achieves greater efficiency. Its internal current regulating circuit contains several components, such as a junction-field-effect transistor (JFET), a linear voltage regulator and a 7-bit digital pass-control circuit.In addition, JFET acts as a switch to regulate the brightness, while a linear voltage regulator guarantees the stability of the power supply. The 7-bit digital pass-control circuit is responsible for debugging the luminous flux of LED lightings, simplifying the complex process to adjust the luminous flux. By combining these three parts, LTST-M670KFKT can gradually and accurately adjust the brightness of LED lighting from sky’s brightness to dim.

Conclusion

LTST-M670KFKT integrates excellent design features and advanced working principles. It is capable of being applied in varieties of application fields, such as Automotive Lights, Industrial Lighting, Spot Lights, and Street Lights. It features one stage effects and its internal current regulating circuit contains JFET, Linear Voltage Regulator and 7-bit digital pass-control circuit. All of the functions make LTST-M670KFKT the ideal choice for LED lighting, providing brighter LED comparable to T-8 fluorescent lamps and calibrated output, making it a better alternative compared with other lighting solutions.
