Everlux RL

Reflecto-luminescent signs are a unique product which offer the advantage of combining two sign concepts; i.e. retro-reflection and photoluminescence (phosphorescence). This allows the sign to perform a dual function:

When the sign is met with external direct light in the form of vehicle headlights or torchlight it reacts in a retro-reflective manner such as traffic signs do. The light is reflected back in the same direction as its source which allows total visibility of the sign and its inherent message;
In the absence of light, the photoluminescent (phosphorescent) properties of the sign emit light in the form of stored energy which is absorbed from surrounding light and direct light from vehicle headlights. This process allows the sign to communicate its inherent message for a period of time.

Everlux-RL signs are manufactured using a LLL (Low Location Lighting) pigment which has been specifically developed for areas of diminished surrounding light.

Everlux-RL signs are also extremely effective in situations where Fire and Rescue Services need to locate fire-fighting equipment such as risers or hydrants. The retro-reflective properties of the signs allow quick identification of the equipment either from vehicle headlights or by torchlight.

It is the ideal marking solution for car parks, warehouses and mines.

Technical characteristics

Retro-reflective properties:

The retro-reflective backing used in Everlux-RL products meets the coefficient values of retro-reflective products as specified in the European Norm EN 12899-1 for vertical signs.

Considering a 20’ (0.33º) angle of observation and a +5º entrance angle, the values for the retro-reflection coefficient are as follows:

Retro-reflective backing in white	Coefficient of retro-reflective lux.m2
EN 12899-1	50
	60

Photoluminescent (phosphorescent) properties:

The Everlux-RL products demonstrate the following photoluminescent properties:

Product	Luminance properties (mcd/m2):		Period of light decay (minutes)
Product	10 minutes	60 minutes	Luminance intensity greater than a 0,3 mcd/m2
	57 (1)	7 (1)	845 (1)
	28 (2)	3.6( 2)	460 (2)
	20 (3)	2.9 (3)	380 (3)

(1) Values obtained in tests by stimulation with a Xenon bulb, with 1000lux for 5 minutes, according to DIN 67510-1.

(2) Values obtained in tests by stimulation with an OSRAM L18W/765 daylight effect bulb (6500 K), with 25lux for 15 minutes.

(3) Values obtained in tests by stimulation with an OSRAM L18W/840 white light bulb (4000 K), with 25lux for 15 minutes.
