Indirect lighting

Indirect lighting theory

Like the moonlight to the earth, which is sunlight reflected by the moon.The light is soft, comfortable, and no glare.

MCPET introduction

"MCPET" was developed by Furukawa Electric of Japanandistheworld's first commercially available microporous molded polyethylene terephthalate (PET) sheet.

These sheets have the world’s highest reflectance due totheir ultra-finefoam structure, and allow the secondary processing of autonomous bend processing and mold processing as a consequence of their high rigidity. They have realized increases in optical extraction efficiency, improvements in glare and irregularities, and reductions inlight sources, etc., and expand the freedom of design.

Microcellular foamed sheets possess excellent light reflecting performance, and have been used widely as reflectors for lighting fixtures.

The excellent light reflecting performance has led to a reductioninthenumber of fluorescent lamps, LED, and other light sources required, making a significant contribution to power conservation.

Safety and efficacy

.Safe for human cells
(Difference in Penetration Depth)

Filtered Far UV-C Ultravoilet Light

The 222nm wavelength used with Care222 technology is absorbed by the dead skin layer of stratum corneum and the upper layer of cornea of the eye.


.Why is UV disinfection effective?

Why is UV disinfection effective?

UV lights works by disrupting the DNA or RNA of microorganism such as viruses or bacteria so they cannot replicate. Unlike with chemical treatments or antibiotics, bacteria and viruses cannot become resistant to damage from ultraviolet light.

Patented optical band pass filter


.Joint Development with Columbia university

Joint Development by Ushio and Columbia university

Care222 technology is based on research by Ushio, Inc. a light source solutions company, and Columbia University Center For Radiological Research, a leading research lab for UV radiation.

.Filtering of harmful ultraviolet wavelength (Maybe used in occupied space)

Filtering of harmful
ultraviolet wavelength
(Maybe used in occupied space)

Care222 is a FAR UV-C disinfection technology using 222nm excimer lamps combined with an optical fiber, which blocks wavelength above 230nm that can be potentially harmful to human skin and eyes.

Attention

This is not a result of any demonstration in a real room. Disinfection efficacy varies depending on usage environment and irradiation conditions.
No matter in which mode,at any time,as long as the person(any part of the body) is within 1M distance to UV module, the module will be forced to shut down.

1.In occupied mode. The UV device is on for 15 seconds,and off for 200 seconds.In unoccupied mode, it is on for 15 seconds, off for 30 seconds, repeating, and off automatically if there is unoccupied more than 2 hours.
2.In occupied mode. The UV device is on for 15 seconds,and off for 80 seconds. In unoccupied mode, it is on for 15 seconds, off for 30 seconds, repeating, and off automatically if there is unoccupied more than 2 hours.
3. Longer diameter x shorter diameter (Area where is 0.6 times of central intensity)
4. The time required for virus disinfection is calculated by the peak iradiance in the irradiated area

※UV light works againstmicroorganism which hasRND/DNA such as viruses,bacteria and yeasts.

Attention

※Not all bacteria and viruses are effective

Operation instruction

Occupied mode (8 hours)

Unoccupied mode

Attention

No matter in which mode, the UV module will be off when sensor does not perceive a person for 2 hours.

No matter in which mode, at any time, as long as the person (any part of the body) is within 1M distance to UV module, the module will be forced to shut down.

The threshold limit value, or TLV, of 222nm ultraviolet light that a person can be exposed to per day has been set by the ACGIH(American conference of Governmental Industrial Hygienist) and JIS Z 8812(Measuring Methods of Eye-hazardous Ultraviolet Radiation) at or below 22mJ/cm2)(up to 8 hours per day). Ensure that exposure is within this limit when installing and using Care222® devices. When using Artemis far UVC products, please follow the instruction in the manual.
