The lighting or signaling of stairs and unevenness is a method of decorative lighting increasingly extended, which in turn provides security to people when moving through a certain space, either indoors or outdoors.
To illuminate with LED stairs and unevenness, it is important to plan well and choose well the type of bulb to be used in this type of signage, so that it does not cause discomfort to the eye. The lighting of stairs and unevenness must illuminate and emphasize sufficiently the steps or slopes to save, indicate the difference of level or planes, always avoiding the glare, since it could cause the opposite effect to the desired one. An illumination to signalize a slope or step too powerful can cause that it is not perceived correctly and we stumble. We recommend that the bulbs used, if it is direct lighting, do not exceed the power of 1W per unit.
On the other hand they must be able to be oriented in parallel to the plane or level to signal, at a height close to the ground level. A good option is the use of asymmetrical bulbs, which project the light directly downwards. The integration of LED strips, whether flexible or rigid, is another good option. Keep in mind that warm white color is always somewhat less bright than bright white, making it a highly recommended color option for signage in order to avoid glare.
On long ladders you should avoid placing bulbs on the front of the steps, as the LED bulbs on the higher steps would be at the level of the face, projecting directly over the eyes. On the outside (or long straight ramps inside) can also be projected from the plane of each step upwards, always with very low power (1W or less), placing the lights on the sides of the steps or unevenness, and not in between, also in order to avoid glare, although the best option is to place the bulbs on the wall, transverse to the steps or unevenness.
