Reasons To Choose LED Lights Over Fluorescent Lamps

LED lights are changing the lighting conditions at both workplaces and houses. It is the best option when compared to the incandescent lights and fluorescent lights. These LED lights took the market by storm and so far are the best option present in the industry. There are many benefits with these light emitting diodes. Awareness has started regarding these…

Cheap LED Highbay fiasco. Is it worth it?

With reference to my other blog about the $2 dollar tube story , the following link is another discovery by LUX testing a £12 highbay light. The repercussion could be worst due to the high ceiling installation. Is it worth it? LED Lighting is a long lasting energy saving product. For many, it could last a lifetime if operated a few…

Why LED Tube having same lumens but different lux?

The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source. Lumens are related to lux in that one lux is one lumen per square meter. The difference between the units lumen and lux is that the lux takes into account the area over which the luminous flux is spread. A flux of 1000 lumens, concentrated into an…

The LED Lighting Dilemma: Long lasting Lighting?

Lumileds claims extrapolated 1,000,000 Hours at L70 for LED. It is good news from technology perspective. The Lumileds’ claim is for the LED die. At system level, there are electronic components; thus, lowering the overall product life time by an order of magnitude. It has been proven that LED lighting is long lasting and more reliable than other light sources….

Luminaire Benchmarks

LED Lighting is flexible. For 2 ft x 2 ft replacement, there are a few approaches to replace the 2 ft linear fluorescent. For any replacement, it is important to consider the luminaire as a system. The fluorescent tube has 360 degree with different types of ballast. 30% of the light is reflected backward and lost. The old fluorescent…

How Yellow LED Tube light can help Photo-lithography area

Without suited yellow filters, artificial light as well as daylight will expose substrates coated with photoresist within seconds or minutes with a dose of several mJ/cm2 making reproducible litho-processes impossible.  Today, Yellow LED tube with special UV cut material has enough brightness to illuminate the clean room and to enable reproducible litho-processes. Instead of using UV blocking film or yellow sleeve over…

The Yellow LED light Opportunity

The definition of light, as applied to artificial light sources, is rather distinct. Visible light is only between 400 nanometers (nm) and 780 nm, but “light” is actually more than just what your eye can perceive. When we look at sunlight, we have a much broader spectral range, from somewhere around 300 nm up to 2,000 nm or so. Interestingly,…

The LED dichotomy

Solid state lighting has evolved over time. One of the luminiare design goals is to emulate natural lighting by transforming tiny high intensity light sources into surface lighting soothing for our eyes. The purpose of this blog is to share some innovative technology which is needed to perform this light transformation. As the intensity increases, there will be hot…
