Led lighting marine aquarium


Submit for review my first job on the coverage of the marine aquarium, so do not kick))))

Led lighting was made for the marine aquarium volume 110 liters of water, the size of the aquarium 50*50*50 cm originally stood for 4 fluorescent lamps with a total power of 48 watt factory-built, light them in practice white lamp and allocated a lot of heat.As in the main aquarium inhabitants it is the corals, I made special demands on lighting. Light in a reef aquarium is one of the most important aspects of well-being and successful content. Not only because it directly affects the life and growth of corals but also due to the influence of lighting used on the exterior decorative aquarium and its perception.

Corals need much more light than fish or shrimp. And they look (corals) are best under very specific, blue-violet, light. All this (size, power and spectrum) imposes essential restrictions on the choice of optimal light source for the marine aquarium.

In this case, the diode light has a significant advantage over other technologies is the possibility of flexible spectrum management and capacity, including on a schedule. And this is oceniana opportunity, especially for novices (choose a good range/power of the light without the experience difficult).

Among other advantages of LEDs, it is possible to allocate their durability — when used properly, they can operate for years without significant reduction in effectiveness. I.e. in the long term, LED lighting comes out still cheaper than any other, because there is no need to change the diodes as lamps once a year. Also, the diodes are much less warm water under a lamp — heat is given up at the radiator. From a purely visual features, it is worth mentioning that the point light from the diodes creates “bunnies” in the aquarium, like sun — in moderation, looks quite nice ))

And so, for the manufacture of lamp I needed:

the radiator is an aluminum profile with an area of 2000 cm 2

LEDs:AQ,3 watt ,10000-15000 K,4 PCs.

UVR ultraviolet,1 watt,420nm,4 PCs.

3GR-B blue, wavelength — 445-452 Nm, spectral width 20 Nm.Light power — 590-650 mW at a current of 350 mA, 1000-1100 mW at a current of 700 mA ,5 PCs

3HPD 3 watt,7000 K,8 PCs


60 400-700 PSI,adjustable


Converter 220/12V 300mA

So the lamp will be mounted in the lid, then extracted from there to the factory bulb and choke with the transaction.

Pre-mark and have the LEDs on the heatsink

we manufacture radiator mount to the lid of aluminum 2mm shank and fasten this corner to the radiator

radiator mount to the cover

then try the radiator cap, its location, the proposed point for the holes, drill and fasten the radiator on the M6 bolts to the cover.

Further, all the LEDs are sticking to teleprovodnik glue and solder, one pair 2 blue LEDs at 300mA current from the inverter 220/ 12V, 300 mA, with enable from the button on the lid.

Putting it all into place under the lid

fasten the driver, install safety glass, pre-check the operation of all assemblies, then put on the aquarium and admire)))))
