Description

These Down Lights are jointly developed by Shanghai FUCIDA Company and IICE Inc., exclusively for TESCO Superstores corridor lighting. These Down Lights utilizing U-Tron's UFO Engine technology which has over 6 years of proven success. Incorporating the LED technology to retrofit existing Halogen Down Lights made by Shanghai FUCIDA Company needs careful integration as to maximize the light spread and cooling efficiency. To achieve the best results and minimizing the cost the casings of the Down lights must act as the UFO Engines heat sink, this way we can pack as much as 30 High Power LEDs made by Cree which gives more then 120Lumen per every watt.

Physical Characteristics:

In the following diagrams please note the red color indicates the Shanghai FUCIDA company parts and Blue indicates the U-Tron parts.

In this diagram the reflectors are redesigned to redirect the light the same way it was used in the Halogen technology.

After the modifications:

Cost Analyses:

The savings can reach over 70% compared at the existing lumen out put. Please see the chart bellow which shows side by side the difference between the 200W Halogen and 36 Watt LED. The electricity savings alone will repay the cost of the LED down lights with in 8 months.

The Core LED Technology:

The light source is based on the Cree X-Lamp technology. Cree is the leading manufacture of LEDs today and our efforts of developing Lighting Fixtures mostly based on Cree available technology. Here is the PCB board that will be used in the UFO Engines, depending on the customers requirements any configurations of 30 to 36 chips can be installed.

UFO 36 Down Light Technical Specifications:

Ordering Part Number: 6870-U36-WR5

Also available in other color temperatures

Also available in E40 and E27 sockets.

Mounting Instructions:

A stencil will be available with this manual for hole drilling. The hole size shall be 210 mm in Diameter. Hight clearance should be >350mm. The stopper that comes with the lamps has to properly secure before inserting the reflector cover. The reflector is attached with a metal wire to the main frame of the lamp to minimize injuries caused by falling. Make sure the 3 stoppers are pushed all the way down and securely holding the lamp. Since the LED lights weigh more than Halogen lamps extra caution must be applied when installing. If the false ceiling is not made of firm chalk board a separate metal or wooden plank should be inserted in-between the lamp and the ceilings. See figure 7 for more detail:

Applications:

The 10 to 40 Watt LED Down light has been designed to retrofit existing halogen and incandescent installations or replace them in architectural specifications. The rugged metal body and 50,000 hour lamp life reduce maintenance costs for hospitals and institutions, retail stores, and even landscaping applications.

High efficient LED Power Supply

Unlike other primary side sensing methods that need to know input power and output voltage information, this new scheme provides much better output current regulation since the accuracy is barely affected by transformer winding resistance, switch R DS, output diode forward voltage drop and LED cable voltage drop.
