1. DCworld
Energy Management System
& Energy Efficient Solutions
Lightstar Information Corp. Ltd.

2. Customer Benefits:
• Very easy to use, intelligent system
• Energy savings, reduces the energy cost up to 90%
• Versatile high quality lighting for healthy lifestyle
• Support the environment, Personal Social Responsibility

3. The Key Characteristics Of DC Based
Solutions:
• DC Energy can be stored in electric battery cells. AC Energy cannot be
stored.
• As almost all the electronic equipment operates on DC supply no
voltage conversions are needed.
• Longer Lifetime of lamps and Luminaires without AC/DC drivers
• DC offers higher efficiency than AC; DC transfers more power with
less electrical losses than an equivalent AC transmission line.
• Majority of renewable energy sources have DC output supply.

4. Why DCworld Is Focusing On Lighting?
• Lighting is almost 18% of the world Energy Consumption
• Provides more efficient lighting solutions
• Provides better quality lighting including human centric lighting

5. Applications:
• Parking
• Retail
• School
• Hospital
• Street Light
• …etc.

6. The key advantages of DCworld:
1. A.N.V. (Auto Negotiate Voltage):
- Detects and adjusts to the same lowest voltage lamps and luminaires in one circuit
automatically.
2. Energy Meter Analyzer:
- Ability for measuring and analyzing energy usage.
3. DC P.L.C. (Power Line Communication):
- Combines electricity and data communication in 1 cable
4. Flexible & scalable solutions

7. 5. Dynamic Lighting Control:
- Dynamic lighting control for both white and R.G.B. enabling Human Centric
Lighting applications
6. Open API (Application Programming Interface):
- Allows integration into the 3rd party systems.
7. Wide range of communication methods:
- Ethernet/ WIFI/ RS485/ UART/ ZigBee
8. Centralized DC Power Supply:
- Less heat generation and energy losses (10%—36% lower energy bill than
AC LED systems)

8. DCworld 3 2 1:
3 High Efficiency
 High AC/DC conversion efficiency up to 96%
 High Power Factor up to 100%
 High energy savings
2 Control Efficiency
 User controllable system power
 Effective management of illuminance
1 Safe low-voltage output
• Indoor under 48V DC and outdoor under 200V DC output.

9. Characteristics of DCworld Smart Control
• An IT Infrastructure based control system
• An Innovative system using existing IT infrastructure to access the luminaires
and controllers directly without extra driver/module for best efficiency.
• Easy to operate.
• It reduces the heat problem
• It combines the luminaire systems with server applications
• Scalability/flexibility to fit any scale and local area application
• Software driven to support sensors and other applications as you need
• Lighting control, Scheduling control, Scenario control, Reporting Service
• The system limitation depends on your thinking

10. Characteristics of DCworld Smart Control
DCworld supports an upgradeable system structure from level 1 to level 5.
• Level 1 is the price competitive lamps and power supply system.
• Level 2 adds dimmable and sensor ability.
• Level 3 is controllable by H.M.I (Human Machine Interface, e,g Zigbee or Wall
Switch)
• Level 4 is portable by APP (Lighting Control App or Console)
• Level 5 is schedulable by Server
See examples of the 5 levels in the coming pages

11. How does DC solution work- Level 1
AC
DC power supply converts AC power to DC. The DC lighting controller
controls the system. Very simple and easy to use.
