Results of Purill lighting

No Special Light

Method and Device for Purification and Illumination with Purill LED

light (infra red + warm/cold white)

Application areas Purill: LED light (IR + cold &warm white)

• Water distillation– Cleaning from bacteria, micro-organism, viruses

– Legionella

• Shelf life management– Extending quality of fruits, vegetables

– Extending quality of flowers

– Listeria treatment

• Food cold pasteurization

Water purification areas:

• Last stage of waste water treatment

• Swimming pool water treatment

• Legionella treatment

• Water recycling

• Clean taps and shower heads

• Clean water supply for green houses

Extending Shelf life

• Increases shelf life of fruits, vegetables and fruits

• Kills listeria (on surface and inside food)• Allows to use less refrigeration of food by

killing bacteria• Brightens colors of fruits, vegetables etc • Is usable as energy saving light as well• Helps preventing color change of meat

Food cold pasteurization

• Food packages passing Purill Modulated light will clean this from bacterial and micro-organism contamination

• Beer and other fluid cold pasteurization can be done with the methodology

On next sheets background of the research of this invention

The conditions to which produce is exposed after harvest govern its rate of deterioration

• Increase in post-harvest decay often occurs where produce is washed before packing. Most moulds and bacteria causing decay require free water to establish infection. It may be a problem when produce is sprayed or exposed to high humid air or mist.

“Purill” Technology works in two different ways:

I. The lights stimulate and maintain important physiological processes and biochemical reactions within the tissues and organs (water exchange, respiration, photosynthesis, etc.) that keep these organs of fresh produces alive for much longer time;

II. The lights kill or suppress spoilage or pathogenic micro-organisms in fresh produces and, as the results, increase the shelf life.

Purill can be installed on different facilities (fruits & vegetable shelves, etc.) of grocery and flower stores.

Purill and the Energy Savings Issue

• The halogen incandescent, fluorescent, and metal halide lamps that are common in the stores consume lots of energy

• Purill lighting systems are capable to reduce this energy cost because of the following:

1. LEDs lamps and panels consume from 30 to 200% less energy than lamps are used in the stores;

2. Purill lamps save energy by providing more output per each Watt through the reinforcement of the natural colours of fresh produce.

Life of Purill lights vs. others

Life of Purill LEDs lamps is 100,000 Hours vs.3,000- of Incandescence bulbs or

10,000 Hours for Fluorescence light!

Food irradiation with Purill lights kills the most of microbes in a produce!

A short term exposure (1-5 min) of a produce with Purill light kills up to 99,9% of microorganisms (bacteria and fungi)
