Hi-Step SLIM CK is a new developed soft resin with luminescent materials added to provide long lasting luminescence.
Hi-Step SLIM CK significantly increases visual capability in the dark.
It enhances traditional staircase’s performance that enables a safe and smooth escape.
Hi-Step SLIM CK emits by storing light in luminous band installed at flute of tyre.
As indoor light, can gain required energy by irradiating fluorescent light (200lx) for 20 minutes.
In a dim light place about 30lx, such as stairway room, can pass the JIS standard by irradiation time for more than 20 minutes.
In the 911 event, the terror attack in the United States in 2001, all the stairway lights in the World Trade Center went out of control before collapsed. However many people were able to escape from the building by following the staircase.
How could they escape in the dark? It was because the staircase were painted by luminescent materials. So as in Japan, “luminescent materials” is getting more important to take into consideration under emergency or contingency planning.
Visibility Data
*1 Cut off light for 24 hrs. then irradiate with 200lx of light for 20 minutes. The luminance of the luminance band after 60 minutes have passed.
*2 The time required to reach the luminance shown in the table after irradiating with light under the above conditions. In our company’s judgement, the minimum luminance required for conducting a safe escape is 3mcd/m².
- lx (Lux – one lumen per square metre)
- mcd/m² (Millicandela per square metre)
Degree of Luminance and Brightness
Luminance mcd/m² | Sensation of Brightness in the Dark |
---|---|
5 or above | Extremely bright, objects are clearly discernibled. |
3 | Outlines of objects are discernible. |
2 | Dim and blurred, objects can be roughly discerned. |
1 or below | Objects are barely discernible. |
On the JIS Standard for Luminous Safety Signboards
The JIS Standard (JIS Z9107 Afterglow Luminance on Luminous Safety Signboards), stipulates that afterglow luminance should be 7mcd/m² after 60 minutes.
With Hi-Step SLIM CK, the performance level is reported to be more than double that of the above standard.
