Supermarkets - overall and product lighting with LED light systems

Lighting is a very important element for the presentation of products in supermarkets. A growing number of supermarkets is using LED lighting because the energy saving of LED technology is quite significant. Lumoluce has installed LED lighting in nearly fifty supermarkets and the demand is growing rapidly. LED technology provides full colour mixing, allowing light colour to be adjusted to the type of product. Meats, for instance,  have to be illuminated by light that includes more red to create fresher look. Our aluminium LED profile can be equipped with various colour combinations and the length can be adjusted according to your wishes. This way, every type of product can be lighted with a different colour shade.

 

On the projects page you will get an impression of what our supermarket LED systems look like.

 

 

Freezers and cold stores - LED lighting inside the rooms and units

LED lighting is ideal for lighting products in freezers for its low heat emission.

Besides the low power consumption, the costs for product cooling will decrease considerably. The operation temperature of LEDs lay between -40°C and 80° C and are thus also operable in very cold conditions. LED lights are also ideal for cold stores with very low temperatures. Usually cold stores are installed with fluorescent lighting. Due to the low temperatures tl lamps emit only 50 percent of its light versus 100 percent light with LED technology. Tl lamps also have difficulties starting up at low temperatures, the warming up time is very long. Therefore people often choose to let fluorescent lamps burn continuously, causing the energy consumption to rise. LED lamps have a very fast switching time. Turn the switch and light is on instantaneously. Also LED lamps have a lifetime up to five times longer compared to fluorescent lamps.

 

	Lifetime in hours
LED	50.000 - 100.000
Fluorescent lamps	10.000 - 15.000

 

 

Museums - lighting of artwork and rooms with LED light

A number of museums has already applied LED lighting. Did you know that the Mona Lisa is lighted by LED technology? This was a deliberate decision based on LED’s characteristics. A lighted LED does not emit any ultraviolet or infrared light. Ultraviolet and infrared radiation cause colour fading over time. This is a serious issue, especially for paintings,  because it means the quality of the painting will get worse every year. By using LED lighting in museums,  the original painting colours will not fade away. White LEDs with high quality (supplied by Lumoluce) have a full colour spectrum, making it a good daylight simulator. Colours really come to life when lighted by these LEDs.

 

 

Jewellery - lighting of show cases, displays and areas with LED light

Gold and silver look very appealing when illuminated by LED. When gold gets lighted by the warm white colour, it gets a nice, shiny, yellow glow. Silver, on the other hand, is best lighted with the natural white colour, because it’s whiter. Natural or cool white LEDs are also used to light diamonds or crystal. Whatever jewellery is lighted, all colours are beautifully displayed by the full colour spectrum of Lumoluce LEDs.

Led light can be applied in many light applications - it can be used for any application where in the past halogen, bulbs, TL ... light has been applied. Led light decrease the overall power costs considerably and also it decrease the heat generation. In many applications - buildings this will also induce a considerable reduction in cooling (air conditioning) costs ...

 

 

Shops and stores - lighting of showcases and displays with LED light

Shops and showcases are usually lighted with halogen and CDM-T lighting. Compared to LED these ways of lighting are quite inefficient. With the same light output LED uses half the CDM-T’s power and 5 times less power than halogen. Also the heat production of halogen and CDM-T lamps is a major disadvantage. The heat emission of LED is considerably less. This decrease of power consumption, and thus less heat generation, reduces the air-conditioning costs. This saving is demonstrated by the 120 % rule, a rule that is used for calculating the power consumption with respect to the lighting power consumption.

Old situation

 

	Power consumption
Halogen lamps	5.000 Watt
Air-conditioning	6.000 Watt
Total	11.000 Watt

 

New situation

 

	Power consumption
LED lamps	1.000 Watt
Air-conditioning	1.200 Watt
Total	2.200 Watt

A comparison in lifetime shows that LEDs are superior to Halogen and CDM-T lamps.

 

	Lifetime in hours
LED	50.000 - 100.000
Halogen	1.000 - 4.000
CDM-T	5.000 - 10.000
