Horticulture lighting – how to keep it cool?
That horticulture lighting is hot these days is an understatement. The media attention, dedicated events and manifold speakers attracting the listeners all point out that there is a big future (read capital) behind led lighting in the horti- and agriculture sphere. All the players are preparing their strategies and products to earn a piece of the pie, and so is one of the thermal market leaders, MechaTronix from Taiwan. We speak to Koen Vangorp, CEO of the company.
“The thermal challenges and opportunities in horticulture lighting are from an unprecedented level and will definitely impact the future of our company. Were we started off with cooling of spot lights and down lights ranging from a few hundred to a few thousand lumen, we now end up in the era of kilowatts of energy losses which need to be cooled away, environments with extreme needs on temperature and humidity control, and nothing yet standardized on the market…”
With 3 off-the-shelf available pin fin coolers, all aiming at horticulture lighting projects, we offer the most comprehensive range of standard LED engines ever developed. What makes the CoolBlock® LED Coolers so ideal for horticulture and floriculture top light projects.
Just a few months after the launch of the 2x2MX, the next standardization in outdoor light engines is a fact. This time Lumileds, Ledil and MechaTronix joined forces to create a 2x6 emitter platform for outdoor use. The scope of this LED platform ranges from integration in street lights over high mast applications to industrial high bays. The heart is the Lumileds Luxeon XR-TX, sitting on the MechaTronix CoolBlock® 2x6 LX and covered by the Ledil Strada IP 2x6. Result… an ultra-compact waterproof LED engine, thermally validated, easy to assemble with off-the-shelf available components creating up to 4000 lumen.
Specifically developed around the 2x2MX LED platform, MechaTronix launches a series of patented building kits for outdoor luminaires like stadium lights, high mast and industrial flood lights. The kits dubbed the CoolBeam® platform host 3 up to 12 CoolBlock® 2x2MX LED engines, generating from 5.000 all the way up to 60.000 lumen.
While standardizations have been mainly focusing on retail and indoor lighting application, also the field of industrial lighting is undergoing a same move. Availability of standard building bricks lead to a shorter time to market, crucial in the hectic lighting world of today.
One of the newest and most popular platforms used for outdoor lighting applications is dubbed the 2x2MX platform. 4 high power LEDs (typical 10W), 4 groups of mid power LEDs, or 4 COBs are placed in a square to generate 4000 up to 6000 lumen, and that in a size as compact as 96x96 millimeter. The complete LED engine is IP67 waterproof after assembly, what makes it utmost suitable for outdoor applications like high mast luminaires, industrial flood lights or street lights.
MechaTronix, part of the Eight Lakes Group and headquartered in Kaohsiung Taiwan, announced its next major milestone with the acquisition of Cooling House. Cooling House, based in New Taipei City Wugu Taiwan, is a technology leader in advanced two-phase cooling. Their high power cooling solutions are based on advanced heat pipes and thermosyphons. As experts in remote heat transfer, they can offer innovative thermal solutions that save energy on an application level and that enable system builders to use higher performance electronics components.
New worlds of LED lighting are revealing themselves, worlds we couldn’t dream about just a few years ago…
When Citizen created the “Monster” COB package CLU550, able of creating over 50.000 lumen of light output, it wasn’t so sure yet if anyone would be able to cool it down to temperatures which would lead to the life time this kind of industrial applications would require.
While LED manufacturers are bringing more and more high power COBs to the market like Lumileds COB 1216, Citizen’s CLU550, Cree’s CXB3590 and Bridgelux’s Vero 29, MechaTronix announces their new CoolBay® high bay cooler program. The CoolBay® is a passive round cooler based on the patented CoolTube® quadruple closed-loop heat pipe structure, which makes it the most compact design on the market cooling down up to 35.000 lumen.
Many tier A LED brands like Cree, Citizen and Tridonic have recently boosted their offerings in COB LED packages with new models performing lumen outputs from 10.000 all the way up to 20.000 lumen. As ECO partner of most A LED brands MechaTronix took up the glove to develop a range of high power passive LED coolers.
With the advantage of pin fin LED coolers under tilted position, MechaTronix announces 2 more diameters as standard available. This second generation pin fin coolers is developed for an optimized free air convection under tilted positions of spot and track lights over 45 degrees. Typically under heavy inclined positioning LED coolers need a far more open structure at the side to prevent obstruction of hot raising air.
