2 The Foundation of BioLED Technology Sensitivity of the visual cell is controlled by the substance called rhodopsin, and this substance is created by the decomposed energy from the light which creates the vision for people. If the intensity of illumination decreases, rhodopsin composes and builds up to its right level. Moreover, if this is well composed, vision inure to the dark and this phenomenon is called “Dark Adaptation” Weber’s law can be simply put like the equation below: K = ( R2 – R1 ) / R1 = △ R / R1 (K: Weber’s invariable R1: First stimulation R2: Later stimulation) Weber’s law only regulate whether the human body feels it or not. However, as we have discussed above, BioLED’s intensity of illumination system do not require “not to feel”, but do require the estimate amount so that “human body may feel it based on vision cell, but not by one’s sense.” Concept of BioLED Applied Technologies for BioLED

3 Differentiating Factor 1 : Maintaining minimum intensity of illumination ◈ Guarantee the clear picture of the CCTV by providing the perfect brightness ◈ Almost no differences in power consumption as compared with the power-off condition of normal sensor lighting ◈ Can expect twice as longer LED life by using a lower current than a rated current Normal Sensor Lighting BioLED BioLED Sensor Lighting BioLED Sensor Lighting

4 After 120 seconds Maximum Brightness (40W)Dimming Mode(4W) ◈ Due to 120 seconds of interlock change of intensity of illumination, one’s eye can’t percept ◈ On/off button system which usually decreases the life time of the lamp, BioLED has solved the problem. With low usage of electricity and solving the overheating problem, BioLED can last at least two times longer ◈ Even it gets dim, it never affect CCTV recording Differentiating Factor 2 : Biometric dimming control

5 Interlock Control Differentiating Factor 3 : Interlock control - Cyber Carpet System ◈ Light gradually controlled by sensor (From 100% to 10% brightness, 16 levels) ◈ Controlling system comes with the CPU, therefore no need for a separate controller ◈ Reciprocal interlocking operation between LEDs with the LAN cables (Core patent technology)

6 Independent Controller ◈ Controls to 16 levels of brightness – to minimize potential power usage and to tune every different environment ◈ Helps to avoid malfunction of lighting by hot air from vehicles ◈ Steps of motion sensor [Sensor detects movement => Full brightness for 30 seconds => Light dims for 2 minutes => Minimum brightness maintained] Core Technology Switch to set minimum degree of brightness(16 phases) Interlocking Cable connected
