[INQ. NO. 1611M09] Since its establishment in 2000, DooYoung T&S has specialized in high-powered LED lighting systems featuring low power consumption, high optic efficiency, optimum radiation design, uniform intensity of illumination and a long lifespan of over 50,000 hours.
The company’s “DYSL” series LED lighting systems employ four kinds of radiation technologies as well as LED multi-chip package, high radiation ceramic & adhesive, ceramic coating heat plate and heat sink (radiator panel) and high illumination reflectors.

The combination of high illumination reflector technology and chip on board (COB) surface effectively solves the problems of eye strain, including severe luminance difference between the LED and the surrounding areas, dark shadows and glare. Thanks to the firm’s special technology concerning heat dissipation, the temperature of heat sink can be controlled not to rise high and power LEDs can be applied to the lighting systems.
Considering optimum ratio of heat dissipation, an aluminum heat sink was specially designed. Heat pipe was developed to dissipate high-temperature inner heat of floodlighting. It consists of sealed 16-angle pipes made of aluminum. The pipe is covered by ceramic with good isolation effect and heat conductivity as well as inorganic adhesive. Optimum radiation technology & materials and AC power technology are being applied to lighting devices with high output. Optic efficiency and life span can be maximized with a parallel arrangement of LED.
The firm’s high illumination reflectors are specially designed in a dual layer with 16 angles substantially increasing light concentration and reflection efficiency.
Multiple angles on the reflector plane widen the radiation field far from the light source and enhance radiation.
Making Perfect Replacement for Previous LED Lightings
The maker’s highpowered LED lighting systems with high illumination reflectors are widely
applicable for hangars, maintenance shops for planes, as well as all kinds of industrial and sports purposes, including street lighting, plants with high ceilings, parking lots, terminals, parks, squares, stations, performance halls, large exhibition halls, playgrounds (night lighting), flood lighting, harbors and factories.
Featuring soft and comfortable lighting no glare and shadow, indirect LED lighting systems from the company are suitable especially for supplemental lighting for greenhouse crops.

The DYSL series LED lighting products are very light: DYSL 300W and DYSL 600W weigh 8kg and 10kg per set, respectively.

[INQ. NO. 1611M08] With an etymology “Quoss,” derived from the words “Ubiquitous” and “Essence,” Quoss has been working hard for developing, producing and marketing of bidets for customers’ health with confidence and understanding. All employees of Quoss are working with great pride for improving customers’ health and hygiene by continuously promoting the electronic bidets with accumulated technology and skills over the past 20 years.
the past few years. In fact, over 80% of houses in Japan and Korea have bidets installed. One of the features that made the Q series essential bathroom accessories was that they fit so easily into existing toilets.

they can be conveniently charged in a car. At home, they can replace general lights in case of a shut-off of electricity, by being easily installed in an existing socket. Made of ABS resin, their body part is highly resistant to fl ame.
[INQ. NO. 1611M06] Navray Korea is a young venture enterprise that has steadily manufactured LED lighting products through ceaseless research and development since its foundation in 2009.Acknowledged as an INNOBIZ Company for its technological prowess and expertise in high quality, it acquired the “Green Certification” in 2013, becoming the eighth company in Korea to obtain the certification.

to secure more outstanding longevity of LED lights through maximized heat-protection effects.



and opening. It is easy to install so that it can be easily used for closing and opening windows. The security function has been upgraded with lock function effectively improved, better than the existing lock device, crescent.
ASP-021A is a roller for windows, which facilitates their movement when opening or closing. It endures high-load with very low noise so it is useful for long-term use. The durability test has been completed with 100,000 repetitions of opening and closing tests.
Feroof tiles can be installed on existing asphalt shingles, which saves cost of uninstalling and prevents environmental waste. Feroof stone chip coated steel tiles are very easy to install, therefore, shorten installation time and save the labor cost. The installation requires no special training with weight of each tile about 2.6-7 a piece. They are also very flexible so, when bent during installation, the basecoat will stretch instead of cracking.
The efforts of the company to be the No.1 player in the
Lift sliding window will be lifted 8mm above the rail and slide with the help of a special hardware operation method, thus allowing a large-sized window to be opened easily and smoothly. It provides excellent insulation and air-tightness because of the use of a gasket made of a special material that has excellent durability and restoring force.
