100W LED Grow Light with 3640 Lumens

Solid State LED Grow Lights are gaining traction again, this time with a press release from Dialight (Lumidrives) reporting that the Canadian Standards Association (CSA) has certified for sale its new state of the art SafeSite fixture for sale. Dialight reportedly designed its SafeSite fixture to replaces conventional 175W to 250W metal- halide and high-pressure sodium light sources with 100W LED technology for hazardous location applications. CSA Certification involves stringent testing and requires that all wiring be done with CSA-approved materials.

Additional features and benefits include:

Low power consumption
Universal input supply (120 - 277 VAC)
Suitable for all Class 1, Div 2, Groups A, B, C, D
hazardous environments T4A rated
Patent pending optical design
State of the art solid state lighting source
Self-contained wiring compartment eliminates
additional junction boxes
Weather/corrosion resistant lamp assembly and housing
5 year warranty
Resistant to shock and vibration
Instant on / off response
Wide operating voltage range
Power factor > .9
THD < 20%

This is more good news for anyone looking for a stand alone fixture that could be safely used indoors as LED Grow Lights. The newly approved Solid State Lighting fixture weighs 19lbs and consumes 85-115W (100W nominal) at 110 volts; for a total output of 3640 Lumens ( 70% lumen maintenance over 50,000 operating hours ). Now if they could start offering other models in different spectrums as LED Grow Lights everyone would have a happy holiday season to rejoice over.

Photonic Lattice LEDs are new class of light-emitting device

A bit older, but LEDsmagazine had reported new Solid State LED lighting technology:

Using photonic lattice technology it is possible to build large-area chips that enable ultra-high power sources for projection and other applications, writes Robert Karlicek of Luminus Devices.
The term “power LED” usually describes one of two types of LED assemblies: a conventional 1 mm2 power chip in a power package, or an array of chips (1 mm2 or smaller) combined in one of several different types of power packaging formats (semiconductor chip(s), package, encapsulant and heat sink).

While the performance of power LED devices has improved dramatically over the past 10 years, the basic concepts haven’t changed too much over the past forty years: one or more small LED semiconductor chips attached to a metal packaging structure and covered by an encapsulant/lens to help extract and shape the light output.

Conventional power LEDs have gradually evolved through incremental improvements in semiconductor and packaging materials and manufacturing processes.

Here we describe a new generation of ultra-high-power photonic lattice LEDs, which operate at input powers as high as 100 W and are orders of magnitude brighter than conventional power LEDs. These are the first commercially available LEDs using photonic crystal concepts to manage light extraction from the LED.

Now a 100W per package is impressive no doubt, hopefully this finds itself into the LED Grow Light segment soon.

Taiwan LED Chip maker VPEC gains New patent in the US market

Visual Photonics Epitaxy (VPEC), a Taiwan-based high brightness LED chip maker, recently announced that the company has secured a patent for LEDs with a reflective layer in the USA market, according to a company filing with the Taiwan Stock Exchange (TSE).

Market sources also citied in a recent Chinese-language Economic Daily News (EDN) report indicated that the patent is similar to patents 5008718, 5376580 and 5502316 which Lumileds secured in 1989-1995.

More great news for the High Brightness LED Solid State Lighting industy.

LED chip maker Genesis Photonics announces new patents for white LEDs

Digitimes is reporting that:

Taiwan-based LED chip supplier Genesis Photonics yesterday debuted its latest patents on white LED technology which the company claims can produce a white LED chip without the need to combine a blue LED and phosphor.

Around two years ago, Genesis started volume production of single white LED chips using this technology with most of the products shipping to Japan, said the company. The production cost for this product is not far off from traditional blue and green LEDs. However, as the brightness of LEDs produced using this technology is still not as bright as ordinary ones, few LED makers are adopting the technology and Genesis is partnering with downstream vendors directly, stated company president Hsu Shi-Hong (transliterated from Chinese).

The company also aims for the proportion of revenues from the blue and green LED segments to reach up to 60% and 40%, respectively, in 2008, up from 45% and 55%, respectively at present, the company added. Meanwhile, the company will increase the number of its metal-organic chemical vapor deposition (MOCVD) equipment to over 25 units by the end of 2008, compared to 19 units now, noted the LED chip company.

This should be great news for the overall health of the Solid State LED lighting market, more competition in the LED Grow Light industry is always good.
