　　東芝發布了常溫工作時的光通量高達160～170lm的白色LED“TL1L4系列”，已從2015年2月4日開始量産。TL1L4系列是照明用産品，主要用于LED燈泡、基礎照明燈、筒燈、路燈以及投光燈等。

　　TL1L4系列産品的發光效率高達160lm/W(CCT=5000K、Ra=70@IF=350mA、Ta=25℃時的標稱值)。Ta=85℃時的工作電流最大達到1A。據介紹，與東芝原産品“TL1L3系列”相比，新産品在Ta=85℃的情況下將光通量提高了60%以上，這有助于照明産品提高發光效率、降低功耗。

　　與原産品一樣，新産品也運用了GaN-on-Si(矽基氮化镓)技術，這也是東芝照明用白色LED的一個特點。該系列産品采用3.5mm×3.5mm的透鏡封裝，有色溫從2700K到6500K的九個型號。

She raised her hands and let them lie with strong pressure on his shoulders. "Yaas; well, that's all right, too, suh; I uz on'y a-givin' you a frien'ly aynsweh. I hope you like it." Beppo crept to the door. He came back presently followed by two men. The latter one was dressed in superior fashion to the rest. With a yell Lalage flew across the room and turned the key in the lock. A book containing the pattern record should be kept, in which these catalogue numbers are set down, with a short description to identify the different parts to which the numbers belong, so that all the various details of any machine can at any time be referred to. Besides this description, there should be opposite the catalogue of pattern numbers, ruled spaces, in which to enter the weight of castings, the cost of the pattern, and also the amount of turned, planed, or bored surface on each piece when it is finished, or the time required in fitting, which is the same thing. In this book the assembled parts of each machine should be set down in a separate list, so that orders for castings can be made from the list without other references. This system is the best one known to the writer, and is in substance a plan now adopted in many of the best engineering establishments. A complete system in all things pertaining to drawings and classifications should be rigidly adhered to; any plan is better than none, and the schooling of the mind to be had in the observance of systematic rules is a matter not to be neglected. New plans for promoting system may at any time arise, but such plans cannot be at any [87] time understood and adopted except by those who have cultivated a taste for order and regularity. "I can hear quite well that you are German, and if you were a Netherlander you would not venture on a bike at this moment. If you come here to seize my bikes, I'll deliver them, for I cannot do anything against that, but I refuse to sell them of my own free-will." With Socrates and Plato, scepticism exhibits itself under two new aspects: as an accompaniment of religious belief, and as an element of constructive thought. Thus they represent both the good and the bad side of this tendency: the aspect under which it is a help, and the aspect under which it is a hindrance to scientific investigation. With both philosophers, however, the restriction or negation of human knowledge was a consequence rather than a cause of their theological convictions; nor do they seem to have appreciated its value as a weapon in the controversy with religious unbelief. When Socrates represented the irreconcilable divergence in the explanations of Nature offered by previous thinkers as a sufficient condemnation of their several pretensions, he did not set this fact against the arguments by which a Xenophanes had similarly endeavoured to overthrow the popular mythology; but he looked on it as a fatal consequence of their insane presumption in meddling with the secrets of the gods. On one occasion only, when explaining to Euthydêmus that the invisibility of the gods is no reason for doubting their existence, he argues, somewhat in Butler’s style, that our own minds, whose existence we cannot doubt, are equally invisible.222 And the Platonic Socrates makes it134 his business to demonstrate the universality of human ignorance, not as a caution against dogmatic unbelief, but as a glorification of the divine knowledge; though how we come to know that there is any such knowledge he leaves utterly unexplained. ahead of time, and after every dance, we'd leave them in groups, and have dinner together at nice, funny, foreign restaurants. Spread before us in the iridescent atmosphere, the view extends over Palitana under its blue veil of light smoke, over the verdant plain chequered with plots of brown earth, and the winding ribbon of the Satrunji, a river as sacred to the Ja?ns as the Ganges is to the Brahmins. And far away, vague in the distance, a light shimmering more brightly where all is bright, lies the luminous breadth of the sea. “No,” admitted his pupil. “I think superstition is just believing something somebody else tells you until you are so busy watching out for something to go wrong that you aren’t ‘right on the job’ with your own work—or you are so busy waiting for some good thing to ‘happen’ that you don’t see Opportunity when it comes up because you’re not watching Opportunity—you’re watching Luck, or Omens.” [Pg 239] "That same. She was part Mescalero, anyway." "They're all well at home, but mother's had a tech of her old rheumatiz. Pap's sold his wheat at a dollar and four bits. Peaches about half killed. Had good luck with his lambs. Wheat's lookin' unusually well. Beck Spangler's married Josh Wilson, whose wife died last Fall, leavin' him two little children. Brindle cow's come in fresh, with a nice calf, quarter Jersey. Copperhead's gittin' sassy agin. Holdin' night meetin's and wearin' butternut badges, and talkin' about resistin' draft. Hogs wintered well, and looks as if Pap'd have a nice drove to sell in the Fall. Pap'll put in 'bout 90 acres o' corn, and'll have to hustle his plowin' ez soon's the ground's fit. Little Sammy Woggles had a fight with Beecham's boy, who's six months older, and licked him. Sammy likes school better now than he did. Pap's bought Abraham Lincoln a new suit o' store clothes and the girls have made him some white shirts. He goes to church every Sunday now, and carries a cane. Pap sends his regards to you, Shorty, and mother and the girls want to be kindly remembered. There, take the letter, Shorty, and read it for yourself. I've got to skip out with my squad." "I want my blue negleegy—I must show you my blue negleegy," she panted, up to her elbows in underlinen. "Yes, I heard they dealt badly enough with him, because he would not betray poor Stephen—and for giving the sacrament to that unfortunate scape-grace. They told me he was to be turned from the abbey to-day, so I sent Dick with a few groats to help him on a little—but I don't know yet, whether the lad is come back, for I have not seen him."
