High power LED matrix 3F 
Powerful LED
matrix gaining increasing popularity among manufacturers of lighting
fixtures. Ability to
significantly reduce the cost of construction of the light source,
using the LED chip in a single form factor can not be overemphasized -
the fewer discrete components in the lamp, the easier it is to provide
high availability and reduce the cost of assembly.The following are
recommendations on the use of
matrices 3F at designing fixtures based on them.
Light efficiency
To produce
the matrix 3F uses high-quality crystals of production Epistar with
light impact on the level of 90-100 lm / W .Nevertheless,
powerful light output matrix is much lower than the total yield of the
crystal used. This is due
to the mutual effect of addition / absorption of radiant energy sources
located close to each other (interference). For the
matrix 3F100, for example, light output is about 6000 lm.
It would seem, in this case it is logical to use crystals with lower light output to reduce the cost of the matrix. However, it is worth remembering that the decrease in its efficiency will increase the heat and, consequently, create higher demands for heat dissipation. Given the small compared to the power consumption of the area of dispersion, it is undesirable. In general, the phenomenon of interference applies to all LED light source.
Optics
To generate the desired scatterplot lamp is necessary to use high-quality optics. The relatively small size of the radiating surface has high requirements for quality of glass and geometric dimensions of secondary distribution systems of the world. The surface of the matrix 3F no protrusions and is flat for easy selection svetrasseivayuschih lenses. We propose to use The following types of lenses. Material - borosilicate glass with improved optical characteristics. Light transmission - up to 99% depending on problem, the optics may have the following varieties:Round LP-1
Angle -60 degree. Used in the construction of internal lighting fixtures.No blinding side effect. Material - borosilicate glass with improved optical characteristics. Light transmission - up to 99%
Round LP-2
Angle - 90 degree. Used in the construction of internal lighting fixtures. No blinding side effect. Material - borosilicate glass with improved optical characteristics. Light transmission - up to 99%. Without side-blind effect.

Assembly
Powerful LED matrix equipped with a thick copper substrate with mounting holes. This helps to ensure a reliable contact to the heatsink. However, you should be careful when assembling to avoid damaging the body.Heat-conducting paste, preferably applied to the entire surface of the substrate.
Power source
LED matrix 3F are a group of crystals, connected in series-parallel to reduce the current supply. Power requirements - the standard for high-brightness high-power LEDs.Yuriy Ruban, Rubicon, ltd
