Low temperature lighting and cold storage light fixtures


low temperarature lightingLow temperature and cold storage environments are really challenging regarding lighting. Airfal, manufacturer of industrial and technical lighting, has been developping light fittings to address these challenges, so that you can get enhanced visibility and safety in cold storage environments and in low temperature chain logistics.

Incandescent bulbs, which are scheduled to be discontinued, are not impacted by cold temperatures. However, the light bulbs replacing incandescent bulbs — compact fluorescent lights (CFLs) — are impacted by cold temperature,  though energy efficient.

Exposure to cold temperatures makes it difficult for the common CFLs to heat properly, affecting the level of illumination. Standard compact fluorescent bulbs decrease flux by up to 50 percent at 0 degrees Celsius. For that reason, the lighting industry is including substances in the bulbs, so as to enable compact fluorescent lights to work under temperatures as low as seventeen degrees below zero Celsius. For that reason, compact fluorescent bulbs takes an average warm up time of several minutes to reach full flux.

The TR3 light fixture has been developed for lighting in extreme temperature locations, such as refrigerators, freezers, coolers, and outdoor places in cold weather.

This cold weather light fixture can withstand temperatures of up to –40ºC. The variety of mounting systems allows this light fixture to be installed in places  exposed to very adverse weather conditions such as high winds, snow, heavy rain, etc. This luminaire has a degree of protection of IP 67 offering total protection against dust and against the penetration of water in prolonged immersion.

How to adapt  lighting when growing older

Over time, our eyes become more sensitive and react more strongly to light. It is therefore necessary to do some adjustment in the lighting of the house in order to maintain a good quality of life and sight. Space can become more comfortable even when the signt changes with age.

How does the perception of light change with age?

Changes in vision can occur throughout life, but once you reach a certain age, these changes become even more worrying than simply not seeing objects from a distance. Just like the rest of the body, some muscles of the eye begin to weaken. Have you ever shined a light in one eye and watched the pupil dilate? The muscles involved in this phenomenon are intended to control the quality of the light collected and, as we get older, they find themselves lagging in their reaction time. This implies that the eyes take longer to adapt to dark or bright environments. Other changes may occur such as yellowing of the lens that affects the perception of colors, the appearance of spots or “floating” in the vision caused by particles in the vitreous of the eye and cataracts that cause areas of fog in the eyes. Medical measures may be takento repair these phenomena or improve these conditions, but good lighting may also help to compensate for some of these eye disorders.

What kind of light should be installed to adapt to these changes?

Intense light

The troubled vision due to age can often be solved by simply using more light than usual. This does not necessarily mean that you have to raise the brightness of all the lighting in your home to extreme levels, but you can use bright lights for some tasks, such as table lamps, floor lamps, lighting under cupboards to provide more lighting for activities such as cooking, reading or using the bathroom mirror, etc. That being said, it’s not necessarily a bad idea to increase the general level of lighting in your home.

Ambient lighting

As mentioned above, older eyes have difficulty adjusting to different levels of light as quickly as before. In order to bring as much comfort as possible to the eyes, you need to set up uniform ambient lighting throughout the house. This means that no room should be brighter or darker than another, so there must be smooth transitions from one room to another. The addition of dimmers (dimmers) can also make it easier to adjust light levels in different rooms.

Anti-glare light

The glare of the extremely powerful light emitted by the light bulbs can trigger vision problems and even worse, “eye floaters”. These eye floaters and other eye injuries can cause light scattering in the eye. This increases the sensitivity to glare, which is not the case for low light levels. To avoid glare, make sure your light sources are shaded or not directed directly to the eyes. For example, you can use spots with frosted lenses to hide the light source.

Precision of color

Because the coloring of lenses on the eyes may change, it is important that light sources have a very high CRI or CRI (Color Rendering Index) – usually above 80 – for colors to be more authentic.
