Japanese Lighting Market According to Japan’s Lighting Industry Association (JLMA) statistics, lamps and lighting product development trend will be more and more closed to LED lamps products. As the end of 2014, LED lamps and lighting products in the proportion of shipments reached nearly 70% (view chart). And in the specific classification of LED lamps, […]
Now, the led COB package, in fact, we can know that most of the COB package, including Japan COB packaging technology, they are based on the package of in-board. There is N chips integrated inheritance packaged by the in-board, which is called COB technology. We all know that the underlying substrate is a copper foil, […]
The ballast (resistor ballast) is a device for limiting the flow of sunlight and generating instantaneous high pressure. Following is some difference between the electronic ballast and inductance ballast. Inductance Ballast is an iron core inductance coil, the inductance characteristic is when the current changes in the coil, the magnetic flux changes, resulting in the […]
When LEDs arrived on the market, their tremendous efficiency and money saving potential changed the playing field and lumens, lux and candela finally became obsolete metrics for determining light requirements for plants. Recently, people began referring to PAR, PPF and PPFD as ways to measure light in photosynthetics lighting applications. The purpose of this article […]
The LED stroboscopic effect actually have two concepts: One is strobe which mean the depth of light flux fluctuations, the more violent fluctuation, the depth of strobe more lager. Second is stroboscopic effect which mean the human visual produce negative effects of electric light flicker, the more violent fluctuation, the negative effects more lager, the […]
Under the effect of high temperatures, the structural characteristics of non-metallic materials, insulation materials will change greatly, which manifests itself softened or melted. Ball pressure test is used to test the heat resistance of non-metallic materials and insulating materials. It indicates the requirements of the ball pressure test in IEC60695, UL, IEC884-1, GB / T5169.21-2006, […]
