چکیده
Compared with other light sources, LED source has a longer service life and will not suddenly fail. Due to its high efficiency, energy saving long life, become the most popular at present. However, it is no considered meet application requirements, time that flux decays this level be of LED. This paper introduces approximate method used predict lumen maintenance lamps. The experimental results obtained by are compared TM-21 standard. Eventually, concluded provides more reliability information than original standard, reference, accurate reliable.

Influences of Device Architectures on Characteristics of Organic Light-Emitting Devices Incorporating Ambipolar Blue-Emitting Ter(9,9-diarylfluorenes)
In this article, we report the studies of various device architectures of organic lightemitting devices (OLEDs) incorporating highly efficient blue-emitting and ambipolar carriertransport ter(9,9-diarylfluorene)s, and their influences on device characteristics. The device structures investigated include single-layer devices and multilayer heterostructure devices employing the terfluorene as one...
متن کاملA simple method for water discrimination based on an light emitting diode (LED) photometer.
This work describes the use of a multi-LED photometer for discrimination of mineral water samples, employing chromogenic reagents and chemometric techniques. Forty-five water samples (including 7 different brands of mineral water and samples of deionised, distilled and tap waters) were analysed in a monosegmented flow system, using three different chromogenic reagents (murexide, PAR and eriochr...
متن کاملReliability Prediction Modeling of Semiconductor Light Emitting Device
This paper presents a probabilistic-approach-based reliability prediction model of semiconductor light emitting devices. Using this model with given initial light-emitting performance and degradation behavior otherwise determined by experiment, the reliability function of the devices is obtained, and the results correlate well with experimental results. (Modeling the initial light-emitting perf...
متن کاملLong-Lifetime Polymer Light-Emitting Electrochemical Cells
Polymer light-emitting devices have been divided into two general types: polymer light-emitting diodes (PLEDs) and polymer light-emitting electrochemical cells (PLECs). The advantages of PLEDs include a fast response and relatively long operating lifetime (with proper packaging). However, low-work-function cathodes and/or thin interfacial layers (e.g., LiF) between the metal and the emitting po...
متن کاملComparative evaluation of the effect of Light Emitting Diode (LED) and Quartz Tungsten Halogen (QTH) light curing units on color stability of Filtek Z350 XT
Introduction:Discoloration of the resin-based composites is a common problem in restorative dentistry. There are many factors associated with the discoloration of dental materials in the oral environment. The purpose of this study was to evaluate the color changes in a nano-composite cured with a quartz-tungsten-halogen (QTH) and light emitting diode (LED) unit. Methods:80 disk-shaped specim...
