“Start Your Business With J&C Technology”

We, J&C Tech Co., Ltd. (CEO Jang Min-Jun),
were estabilished decades ago based on accumulated experience and know-how regarding
electro-optical evaluation for Flat Panel Display such as LCD and OLED, and reflectance, transmittance and
haze meter evaluating optical property of films and optical components.

We, as a system provider for LG, Samsung and Seoul Semiconductor have also developed
integrating spheres, Goniophotometer and thermal resistance testers which characterize electric, optical and thermal property of
LED Luminaire, Metal Halide lamp, EL bulb, BL lamp, CFL lamp and etc.

We have lounched high efficacy industrial lighting business combining
experience in test equipment development and consulting & testing service for 3rd party lighting manufacturers from
Instrument division & Lighting division and US patented Solid Capacitor Power Technology, which gives
over 90% efficiency as in SMPS and long life span with semiconductor circuit.


“ Acquired experience & technology in developing LED lighting evaluation systems
Accumulated Knowhow as a test & consulting service for 250 LED lighting manufacturers. ”


Commercialization of light Engine


US panted SCPS(Solid Capacitor Power Supply) utilized LED light Engine can gurantee stable operation under harsh temperature condition such as cold storage house & hot furnice.


High Efficacy & User frendly


over 90% power conversion efficiency and 240Hz driving frequency and give apparent brightness enhancement (BROCA-SULZER Effect, 1.2 times brighter under same illuminance).


Optimum light envirenment relized


Optimized for industrial application such as security lighting, Factory highbay, Cold storage house and logistics warehouse gives upto 90% energy saving.
