The phosphor-conversion white LED as a whole consists of four major components: the LED chip, phosphor, encapsulant, and heat sink (Fig. 1). The following discussion focuses on the dichromatic white with occasional extension into multiphosphor technique, including research efforts and future research...
The invention relates to a method for acquiring high color rendering LED white light by using combination of a white light LED and a red light LED. The method is implemented by the white light LED, the red light LED and a control circuit. The white light LED consists of a blue light ...
a. Light consists of EM waves. b. Light is made of photons, as Einstein figured out. c. Light is a disturbance in the aether. d. Light is both waves and particles but not at the same time. What would happen if gray matter ...
White-light emission is achieved by partial energy transfer (ET) between donor and acceptor molecules anchored on the inorganic component. The unique and remarkable processability feature of these hybrids is demonstrated by painting/writing onto large glass and flexible plastic substrates.关键词:...
In this paper, we report a very rare circular white-light flare that consists of several bright kernels in the white-light continuum, as well as in the Hα line and ultraviolet (UV) channels. In particular, this flare possesses two categories of white-light kernels, i.e., impulsive kernel...
White pulp consists of PALS, each with a splenic lymphoid follicle surrounded by a marginal zone. Normally these foci of white pulp are so small that they may not be visible on gross examination of a cross section of the spleen. However, if nodules are enlarged either by lymphoid hyperplasia...
An assembly is described that consists of a gallium arsenide die chip and a fiber optic coupler bonded together about their respective mating surfaces. The chip includes laser light emitters. The fiber optic coupler has fiber optic light... RR Hall,HT Lin - US 被引量: 95发表: 2001年 Improv...
Highly efficient phosphorescent white organic light-emitting diodes (WOLEDs) with stable emission spectra are successfully fabricated by using an RGB three-color separately monochromatic emission layer (EML) structure. The EML consists o... ZQ Zhang,YP Liu,YF Dai,... - 《中国物理快报(英文版)》...
An oral vaccination has been developed and consists of a nonpathogenic strain of E. magna. This vaccine is sprayed into the nest box when rabbits are 25 days of age. The preweanling rabbits develop immunity subsequent to infection with the nonpathogenic strain and are then resistant to wild-...
Of the small amount of phenolic material found in white wines, most consists of readily soluble nonflavonoids (hydroxycinnamates), such as caftaric acid (caffeoyl tartaric acid) and the related derivatives, p-coumaric acid and ferulic acid (Lee and Jaworski, 1987). The treatment of the juice ...
