LED ultra-low temperature freezer lamp NLFZ series
Feature
NLFZ series are LED lamps specially designed for freezers.
In an environment of minus
60°C, general LEDs and internal electronic components usually cannot operate.
However,
the NLFZ series lamps are equipped with an internal temperature-appropriate heating device,
which automatically heats up when the temperature reaches minus 15°C, and automatically
stops heating when it reaches 0°C to adjust the internal temperature of the
lamp.
Condensation countermeasures: The ePTFE film breathable valve is used to prevent
condensation due to a filter material that can only pass through air but cannot be
penetrated by water droplets.
The independently developed power module is equipped with
various protection circuits.
※The hanging model is equipped with an anti-fall steel cable
for added safety protection.
Applicable
Large freezers, refrigerated warehouses, and various ultra-low temperature environments.
Low temperature freezer lighting
In recent years, low-temperature freezing technology has been advancing rapidly. With the advancement of low-temperature freezing technology, Nikki's ultra-low temperature freezer lamps are also using its superb LED lighting manufacturing technology in refrigerated warehouses everywhere. All kinds of ingredients, fruits and vegetables can be supplied in a fresh state anytime and anywhere without seasonal restrictions; making our lives very rich.
Japanese refrigerated warehouse temperature grades
Warehouses with storage temperatures below -20°C to 10°C are classified as Class C
(refrigerated).
Warehouses with storage temperatures of -20°C or lower are called Class F
(frozen).
Freezer warehouse refers to Class F.
| grade | illustrate |
|---|---|
| Level C3 | Below +10℃~less than -2℃ |
| Level C2 | Below -2℃~less than -10℃ |
| Level C1 | Below -10℃~less than -20℃ |
| F1 level | Below -20℃~less than -30℃ |
| F2 level | Below -30℃~less than -40℃ |
| F3 level | Below -40℃~less than -50℃ |
| F4 level | -50℃ or less |

Lamp plus temperature adjustment module
When the sensor switch inside the light source senses that the temperature is lower than -15°C, the sensor switch automatically starts the heating module.
The heating module will automatically turn off when the temperature reaches 0°C.
Silicone wire
Generally, the ambient temperature for use of PVC wires is -20℃~60℃, but because the Nikki uses silicone wires, it can adapt to the ambient temperature of -60℃~150℃; it can be used with peace of mind even in special environments with low temperatures and severe cold.
heater module
The power module is equipped with a heater, and the temperature will not fall below -40°C.
Heating module wiring diagram
Lamps and heaters are available in AC110V and AC220V specifications.
Gentle light source without flicker
The safe flicker rate recommended in IEEE 1789 (Standard for Effects and Evaluation of Lighting Flicker) is 8%, while flicker is almost undetectable to the human eye at about 3%.
Nikki product adopt an exclusive design to further reduce the flicker rate to less than 2%. Not only will there be no flicker at all when shooting general still photos and videos, but it can also use 240fps There will be no stripe flicker when shooting with high frame rate equipment. It is very suitable for application scenarios such as image inspection and appearance inspection that require high-precision photography or long-term naked eye observation.
※The picture below shows the situation under the light source of a Nikki product.
