Considering About the Brightness Stability and Energy Saving of the LED Lighting

Brightness light-emitting diode varies with the size of the current and manufactured light-emitting diode, the voltage and current curves slightly different, and therefore the led street light wholesale, often with changes in supply voltage can not be stable. In order to maintain stable and consistent brightness, light-emitting diodes require constant drive to achieve. Constant current driver in a light emitting diode can be made constant current mode, and thus high brightness stability.

Constant current driver also allows light emitting diodes to some current long-term work to maintain a longer life.TM Technology ‘s T6316 is a constant current drive, it is having a four-channel constant current LED driver, the output current can be in accordance with an external resistor. T6316 with accuracy to ± 6% ± 3% with the channel current matching accuracy, can be used for street lighting, lamps and other lighting equipment.

To save energy, the system design should be considered constant voltage across the drive between 0.5V 2V. As the light-emitting diode work long hours at a constant current, the voltage across its slight decline, this change should also be considered in the system design.LED lighting advantage is energy saving, safe, but because of the constant current work considered relatively energy consumption increases, so the lighting system design with low power consumption as the goal.

The aforementioned constant pressure drop within the drive 2V, ie, low power consumption design is considered, if the power supply voltage terminal in series with a lighting system than a diode drop above 2V, the voltage converter is required to consider the target to achieve low power consumption but maintain a constant current mode. The voltage converter is a low -power switching manner, according to the feedback circuit controls the switching period, to stabilize the output voltage. However, in order to maintain the current operating state of the light emitting diode constant, the output current of the feedback circuit is to control the converter switching cycle.

TM Technology T6322 is a step-down constant current LED driver, the current decision in accordance with an external resistor, can support up to 1.5A output current, providing ± 5% accuracy current and high power performance (energy consumption) and high capacity electric line regulation.In the current market is flooded with LED lighting products, their power input system into two categories: one for the front of the rear end of the AC power input system coupled with constant current control module, such products include freezer lights, indoor lighting, street lights, lamp, MR16, AR111, etc.

Another direct input AC power system integration AC / DC converter and a constant current circuit, including such products, such as E27 and GU10 LED lamp bulb, PAR lamps, T5 and T8 LED tube and so on.The first category should be selected in addition to the front-end power supply design better efficiency constant-voltage power supply, the rear end of the constant power supply module is controlled by the use of product characteristics according to their efficiency better power supply design. The advantage is that the front-end led street light wholesale power supply, such as switching power supplies, DC power adapter and other constant voltage, selectable high and more than a safety certification program, designed to reduce the threshold.

Currently LED lighting products to achieve high luminous efficiency, and become the next generation of the main light source, the primary consideration is the design of the power modules for different products to choose the right lighting design architecture. In addition, the power supply control IC must also improve power efficiency, power factor, reliability, to develop demand for LED lighting products.More info you can visit: ·RELATED QUESTION

What's the meaning of Sia's Chandelier song?

Before Chandelier, Sia was a singer with mediocre success.

She was really struggling to push her career when she lost her partner to an accident. She got addicted to drugs, suffered depression and even wrote a suicide note. Drugs and alcohol were her only coping mechanisms. This song is about the time she was addicted to alcohol and drugs and her struggle to get out of it.

In an interview, Sia said that she always knew she was a drinker and that she must stop, her guilt, shame is what the following lyrics suggest:-

Sun is up, I'm a mess

Gotta get out now, gotta run from this

Here comes the shame, here comes the shame

.. but, out of peer pressure

phones blowing up, they're ringing my door bells, I feel the love

..she did not stop.

1,2,3 ... 1,2,3 drink

throw them back till I lose count

The only time she could escape from reality was when she was high, under the influence of alcohol and drugs. She could be carefree, live like tomorrow didn't exist.

I'm gonna swing from the chandelier, from the chandelier

I'm gonna live like tomorrow doesn't exist

Like it doesn't exist

I'm gonna fly like a bird through the night

Chandelier is ultimately a brutally honest tale of substance abuse.

Sia wrote the song for Rihanna but I am so glad that she kept this one for herself.

What Are the Effects on Hearing of in Ear Headphones?
The main effect on hearing is the volume of the sound. Both the intensity and duration matter. However, it seems like hearing loss from personal music players is not as prevalent as from other causes like gunfire or occupational noise exposure (see also here).The specific problem with in-ear headphones is people tend to listen to them louder than other types of headphones, here is an example study that shows this result. So, in summary, there is not anything wrong with in-ear headphones if you listen at a low volume, but be wary that peoples' tendency is to listen louder with in-ear headphones, and you already mentioned liking loud music. The volume is going to be your problem.Be very wary with your hearing though: once you have lost hearing, there is no way to get it back at this time. Hearing aids only temporarily compensate for the loss. You might be okay now but regret a lifetime of noise exposure by the time you are an older adult.References:Clark, W. W. (1991). Noise exposure from leisure activities: a review. The Journal of the Acoustical Society of America, 90(1), 175-181. Hodgetts, W. E. , Rieger, J. M. , & Szarko, R. A. (2007).

Best Cheap On Ear Headphones?Sorry, but quality DOES have a price and it is NOT that low! If REAL quality is an issue, please go for REPUTABLE brands only such as B&W, Sennheiser (most affordable), Shure, Grado, Denon, AKG, Audio-Technica (NOT to be mixed with Technic which is utter rubbish as well!), Etymotic or Beyerdynamic. Things like V-Moda, Klipsch, Sony, Panasonic, JVC and Philips are ONLY "okay-ish" indeed. Please do NOT fall a victim to FASHION ACCESSORIES by buying Boombox, Ministry of Sound, Sol/Republic/Revolution, Noontec Zoro's, Benetton, a-jays, iFrogz, Marley, Fanny Wang, Razer, Karl Kani, WESC, Turtle, JH, Dr.Dre/Beats/Solo, Ludacris/Soul, Koss, Skullcandy, Lady GaGa, Skullcrushers, Monsters nor Bose, because they are ALL seriously overhyped and overpriced "fashion blingbling gimmicks" with a very poor durability and sound quality, NOTHING else (and those who try to claim they are good do NOT know ANYTHING about QUALITY anyway!), BE THEM FAKE OR NOT! Also, please do NOT go for the overly thumping bass that only distorts everything else, focus on GOOD sound quality and durability IN GENERAL.2. What is the best pair of over-the-ear headphones?Panasonic Retro Headphones - (RP-HTX7-G1) *This model number is for the green ones which I have, There is also Red and White..and if you search online, Pink can be found* I bought these at Target on sale for $39.99 They are by far the best headphones that I've ever had. (And the cutest!) They are also very soft, and cushy so they do not hurt your ears. Regular price (At Target) Is $57.99, but they can be found online cheaper.3. What are the best over the ear headphones for sound quality and noise insulation?Well, according to hi-if afficionado Steve Gutenberg these headphones are THE best in the world:Abyss AB-1266 headphones run $5,495, but they are worth itNow, you can try on your Sony's, Sennheisers, AKG, Beyer etc but if you want some excellent headphones those are for mere paupers. Sell that new car back to the dealership and buy a runaround and make yourself truly happy... life is simple than you think!Qualifier:i do not sell audio equipment for a living, nor work in any aspect of audio. I use audio equipment at home. I do not own a pair of the above headphones because I know I will listen too much and too loud on them and so would finish off my hearing. Steve Guttenberg has been in audio a very long time and has been a professional reviewer for many many years. He has listened to probably many hundreds of headphones over the years (along with much other home audio equipment). I enjoy his YouTube channel as the shorts are just enough to watch each episode. I am not affiliated to Steve Guttenberg in any way.What are the best over the ear headphones for sound quality and noise insulation?
