Tunable duxit modules secundum CSP-Cob
Abstract: Research est indicavit per correlationem inter color de lumine fontes et humanum circadian cycle.color tuning ad environmental necessitates facta magis et magis in altum qualitas lucis applications.a perfectam spectro lucis ut exhibeant qualitates closest ad solis spectro de lumine ut exhibeant qualitates closest ad solis spectro de lumine ut exhibent qualitates proximi ad humana sensibilibus. Humanum Centric (HCL) necessitates esse machinator secundum mutare environment ut multi-usu facilities, classrooms, salutem cura et creare ambience et aesthetica. Tunable duxit modules sunt developed per combining chip scale packages (CSP) et chip in tabula (CAB) Technology. CSPs are integrated on a COB board to achieve high power density and color uniformity，while adding new function of color tunability.The resulting light source can be continuously tuned from bright,cooler colored lighting during the day to dimmer，warmer lighting in the evening,This paper details the design,process,and performance of the LED modules and its application in warm- dimming LED down light and pendant light.

Introductio
Et ducitur ut scimus quia supra L annis. The recent development of white LEDs is what has brought it into the public eye as a replacement for other white light sources.Comparing to the traditional light sources，LED not only presents the advantages of energy saving and long lifetime,but also opens the door to new design flexibility for digitizing and color tuning.There are two primary ways of producing white light-emitting diodes (WLEDs)that generate high-intensity white light.One is to use individual LEDs that Emit tres primaria coloribus, rubrum, viridis et hyacintho et tum miscere tres colores formare alba Light.The Alii est ut phosphor materiae ad conversus Monochromatic albus et hyacintho, quod est in eodem modo in lupo, ut non semper est ut in eo ut alba, ut non semper est ut sit in eo ut non semper est ut sit in eo ut alba, ut non semper est ut non semper est ut idoneus est ut non semper est ut sit in eo ut non semper est ut sit in eo ut alba, ut non semper esse ut in eo ut non semper est ut sit in eo quod est in albis Lux.

LED Luminaires cum facultatem ad libera varie lux color fuisse in architecturae lucendi foro cum diluculo diebus solidum-statu lucendi (SSL) .though, tunable lucendi manet in speciem et requirit quodammodo congue sem manet in speciem et requirit quodammodo congue sem manet in speciem et requirit quodammodo congue sem manet in speciem, si ad installation est in speciem, si est ad prospere Duis congue sem permanet, si est in proficisci, quod est in proficisci, ut sit amet elit. There are three basic categories of color-tuning types in LED luminaires: white tuning,dim-to-warm, and full-color-tuning.All the three categories can be controlled by a wireless transmitter using Zigbee，Wi-Fi,Bluetooth or other protocols，and are hardwired to building power.Because of these options,LED provides possible solutions to change color or CCT to meet the human circadian rhythmis.
Circadian rhythms
Plantis et animalibus exhibent exemplaria morum et physiologica mutationes super an circa XXIV-horas cycle quod repetere super successive dies, hi circadian rhythms.circadian rhythms sunt motus et endogenous numeris.
Et circadian rhythm regitur per Melantinin quod est unum de Maior Hormones produci in cerebrum. And it induces sleepiness also.Melanopsin receptors set the circadian phase with blue light uponwaking by shutting down melatonin production".Exposure to the same blue wavelengths of light in the evening will interfere with sleep and disrupt the circadian rhythm. Circadian desynchronization prevents the body from fully entering the various phases of sleep，which is a critical restorative time for the human Body.furchormore, impulsum circadian perturbatio extendat ultra mordilitionduring die somnus nocte.
Circa biologicum numeris in hominibus potest metiri in pluribus solet, somno / excito cycle, core corpus temperatus, melatonicconcentration, cortisol concentration, et alpha amythmi per circuitum, leo afficit, quod in lucem, et Distribution.That et Duration Durationis, System.That Humanum, System.That Mens Durationis, Vimnitas Humanum System.That afficit Durationis, Vesitim Didy.that Internum horologium etiam. The time of light exposure can either advance or delay theinternal clock".The circadian rhythms will influence the human's performance and comfort etc.The human circadian system is most sensitive tolight at 460nm (blue region of the visiblespectrum), whereas the visual system is mostsensitive to 555nm (green region). So how to use the tunable CCT and intensity to improve the quality of life is becoming more and more important.Color Tunable LEDs cum integrated sensu et imperium system potest developed ad occursum talis altus perficientur, sanus lucentes requisita.

Comparet ad structuram III, structuram I habet tres incommoda:
(A) Color miscentes inter alia CSP lux fontibus in diversis CCNTS non uniformis ex segregatione phosphor Silicone fecit per Chips CSP lux fontibus;
(B) CSP lux fonte est laedi facile cum corporis tactus;
(C) Quod gap cuiusque CSP lux fons est facile ad captionem pulvere ad causam Cob lumen reductionem;
Structura2 etiam habet suum incommoda:
(A) difficultas in vestibulum processus imperium et cie imperium;
(B) color miscentes inter diversas Cct sectiones non uniformis, praesertim pro proxima agro exemplar.

Applications
In accedente usura structuram III, ibi sunt duo diversa circuitu consilia ad lucem color et splendorem tuning. In uno-channel Circuit quod habet a simplex coegi postulationem, albus CSP linea et hyacintho flip-chip filum sunt in parallel.There est certa resistorin CSP linea. Cum resistor, et driving current est divisa inter CSPs et hyacintho eu fit mutatio de color et claritas.The detailed tuning results are ostensum est in mensa I et Figura Circuite ostensum est in Figulis Single-Circuite. Et CCCT augmentum ad agitantem current. Nos cognovi duos tuning mores cum aliquis emulantes conventional halogen bulos ad alia linearibus tuning. Tunabula CCT range a 1800k ad 3000K.

Summary
Tunable duxit modules sunt developed per combining
Chip scale packages (CSP) et chip in tabula (Cob) technology. Cspsand blue Flip chip sunt integrated in MANNUS tabula ad consequi princeps virtutis density et color uniformitatem, dual-channel structuram adhibetur ad consequi latius Cct tuning in applications sicut commercial lucendi. Una-alveo structuram adhibetur ad consequi dim-ad-calidum munus emulantes halogen lucerna in applications sicut domum et hospitalitatem.
