BEAMS systems

 

​​


 
To successfully maintain photosynthetic corals in a home aquarium, we should provide them with the conditions, as close as possible to those in their natural habitat. One of the most important conditions to maintain corals in a healthy state is proper lighting.

First of all, the lighting should have a certain spectrum, furthermore, this spectrum should be identical for each point of its lighted surface, because in nature all parts of the coral receive the lighting of the same spectrum.


Secondly, lighting should be even by force across all the lighted area, as in their natural habitat the corals’ living the surface of the light exposure is even with its area.
.


 



Unfortunately, no one has managed to fully fulfill those requirements. Our company has been researching those questions for 5 years. In this time, we have produced plenty of light-emitting-device decisions which consistently approached the fulfillment of these tasks. BEAMS system, which has incorporated all our experience and many years of practical experience of thousands of our customers, is a revolutionary step ahead in resolutions of these most important problems. For the first time, BEAMS system allows to say that these problems are almost entirely resolved. BEAMS system additionally provides convenience in assembling the light-emitting-device lamp which was unattainable earlier.

BEAMS abbreviation stands for:

B - basic. It is the main, base, the filling lighting. 
E - even. BEAMS system provides a more even lighting than Т5 lamps.
- aquarium. The system is developed regarding the needs of the photo synthetics in marine and fresh-water aquariums.
M - modular. Never before was aquarium lighting as modular.
S - system. BEAMS is not simply a set of different components, it is a system, where each element was developed specifically for it.

BEAMS system consists of two main components - ultra-dense light-emitting-device assembly and driver module with a controller.

At the moment, there is no even remotely similar analogues of BEAMS light-emitting-device assemblies, which could be compared to them in this set of specifications.

At the moment, there is no even remotely similar analogs of BEAMS driver assemblies, which could be compared to them in this set of specifications.. 
 
Let’s study how BEAMS system resolves different problems.
  • 1. What uniformity of spectrum BEAMS system provides?

    When we talk about the influence on corals of one or another spectrum, it only makes sense in case these two requirements are fulfilled.

    1. When we precisely know what spectrum is formed by the lamp. This issue was successfully resolved by TrueSpectrum controller a long time ago.

    2. When the spectrum is exactly what we would like to generate in each point of the target surface. This task is solved the better, the more closely are the LEDs located on the assembly. There is a video made by BRS regarding this topic, which we recommend strongly:

    This video shows the spread of the spectrums to the lighted area for a typical LED lamp of a marine aquarium from 6:13. Here we will quote only two of the measured spectrums.



    Notably, these spectrums are generated in perfect conditions for this lamp, being when all LEDs are included.

    To check the heterogeneity of the spectrum of BEAMS system one LEDs assembly was measured, meaning the worst case. All LEDs were at 100% brightness. For the best perception spectrums were evened by their total radiation:

    As you can see, the uniformity of the spectrums is close to ideal.

  • 2. How much radiation in PAR and how even is the lighting provided by the BEAMS system?

    Briefly, BEAMS system provides maximum lighting, which is double that of T5 lamps and much more even light distribution over the lighted area.

    Now we’ll demonstrate it in detail.

    The measurements for the BEAMS system were carried out with six LED assemblies put together in this chain:

    The distance between the centers of the first and the last LED assemblies was 68 cm.

    The test field was 40cm away from the BEAMS system. The size of the test field was 70x130cm, the side of a square was 10cm.

    This is the lighting in PAR given by the BEAMS system.
    On the left without reflectors; and on the right with the plainest reflectors, which are just vertical strips of paper located next to the LED assemblies:

    A single T5tube of the same length, located at the same height above the lighted surface, in the middle of the lighted area, so in a spot with maximum lighting, gives 20-25 PAR without a reflector and 40-45 with a reflector.

    Please note that in the 30x70cm area the uniformity of lighting is almost ideal fluctuating by less than 20%:


    Let's see what lighting uniformity is provided by T5 lamps in similar. Let's return to the BRS video:


    From 15:26, we can see the light scatter under a 24W lamp T5 lightbulbs. With a length close to the BEAMS length for an aquarium with a surface area of 2x2 feet, the sizes of the lamp and the dimensions of the aquarium are close to the BEAMS ones. Here' s the screenshot:

    As you can see, the lighting illumination in the field of the lamp luminaire changes from PAR over 380 to PAR of about 100, which is more than 3 times.
     

  • 3. How simple is assembling BEAMS?

    The components of the BEAMS system are assembled by installing flat power cables in the ZIF connectors, meaning zero installation effort. All necessary assembly cables are fully ready for the installation. The driver assembly is fully configured during production, you do not need to install any jumpers. All that is required is to connect the components by flat cables and the light is almost ready!

    For someone who does this for the first time in their life it’ll take about 5 minutes to assemble this configuration of BEAMS, please click on the picture to open in larger size:

    If you are not doing this for the first time, then it will take no more than a couple of minutes.

    Separately, we like to emphasize that all BEAMS components are designed not only for convenience and speed of the assembly but also to prevent the assembler from any errors. For example, there is a protection against repolarization at the power input of the driver assembly which would completely protect the user when the polarity of the supply is connected incorrectly. For more information on the circuit solutions that facilitate assembly and enhance the reliability of the BEAMS system, please see the description of the relevant components.

  • 4. What else does BEAMS provide, which it did not have previously?

    1. A unified diffuser, which reduces the already small heterogeneity error of the spectrum over the lighting area by about a third. It also acts as a protective glass.

    2. New long-term thermal interfaces, from cheap to the expensive ones with the highest thermal conductivity in two options with an adhesive layer and without.

    3. The component upgrade is available now. You will be able to add new types of LED assemblies to the existing lamp without any modifications to your components. 

    Additionally, the microcomputer module is now located on a separate board, so it can be replaced with a more advanced one when it comes out if necessary.
