Intelligent LED road lamp - principle

Intelligent street give full consideration to the actual situation of city road lighting, using microcomputer control technology for dynamic illumination of the lamps intelligent management, user-friendly street. Because the LED street lamp with other lamps not transient response splitting characteristics,dcb4a51kk circuit is easy to realize the use of KHZ level pulse width modulation ( PWM ) on LED street lamp light out of duty ratio regulating ( e.g.,1ms0.5ms0.5ms and the bright bright brightness for light50% ) can be adjusted the whole lamp brightness. Working in such a high frequency strobe phenomenon does not exist. Through the lamp set, in the busy periods to maintain a strong illumination lights in the midnight, after the car is little begins when the automatic light adjustment, so that to maintain a more low-light street lighting. Also through internal programmer according to different city prosperity, lighting live, traffic flow of artificial illumination setting a mandatory level, set the length of time than the control strength of illumination, after lights can be set in accordance with the new periodically executing program. Namely, the achievement of the local road lighting personalization.

Intelligent LED road lamp - Advantages

In addition LED street lamp light source ( LED ) has very good single direction, light extraction rate is extremely high, and the traditional gas street lamps light source for a full range of luminescence, rely on the reflecting cover together into a single direction light, loss of the larger,Health Supplement light extraction efficiency are greatly inferior to LED Road lamp. So the real in the role of road light effects on the traditional lamp significantly inferior to the LED street lamp. Predictability benefit analysis to 10 km paved700 street lamp comparative economic benefit, the economic benefit analysis for ideal analysis, can actually be from technical parameter table15 and16show the advantage far beyond LED road lamp with ideal analysis.

Intelligent LED road lamp - Remarks

Cable cost algorithm:10 km traditional street lamp cable current I=700*250W/220V≈ 800A, section400mm2for copper core cable, priced at 360 yuan / m, cable cost of 360*10000=360 million, LED street lamp cable current I=700*50W/220V≈ 150A, section40mm2for copper core cable, priced at 60 yuan / m, cost 600000 yuan

Cost:10 hours to day lighting calculation method, to0.65 yuan per kilowatt-hour calculation, traditional street lamps a year total power consumption of700*250W*365*10h*0.65 ≈ 415187( KWH ) of alloy element, LED street lamp one year total power consumption : 700*50W*365*10h*0.65=83037( KWH ) of83037yuan.

Light source life comparison, traditional street3000-4000 hours, LED street lamp life of 40000 hours or more, are in circulation today best HPS 5times over the lifetime,T8 LED lamp high pressure sodium lamp replacement of more than 5, LED street lamp is changed once, such as is generated by the light source cost, maintenance and so on cost. From the above analysis visible installation path longer traditional street lights and LED lights price more clear.

With the continuous development of LED technology, LED price is climbed ceaselessly litre, LED light source to gradually replace the traditional light source of semiconductor green lighting is not far away!

Baby pillow height how to choose?

Market sales of baby pillow lot, allowing parents to see things in a blur, do not know how to buy, do not know how to choose, choose baby pillow is indeed a very learned. So baby pillow height how to choose? Baby pillow type, how to choose?

For 0-3months baby, their spine is straight, back height and head height, while their spine has not yet mature, if this period choose baby baby pillow, is a failure of the decision, this time the baby if the pillow, can cause spinal curvature, will cause serious respiratory problems, so this period of baby can not any pillow pillow,wholesale baby clothes suppliers or take a large bath towel, folded into seventy percent off pad in the baby's head, the height is the maximum height of the newborn baby can receive.

After 3 months of the baby can be looked up, also want to practice again, this time the baby's spine starts to bend, has begun to like the adult spine development, this period can begin to choose the baby baby pillow, this period if continue to give baby pillow towel suit not quite, this time baby pillow can choose height of 3,4 cm of the baby pillow, can do or go to the shop to buy, of course if they do the height of the pillow can be adjusted, more suitable for their own baby. Pillow material must choose pure cotton fabric, stuffing inside the best choice of buckwheat husk, breathable, Xihan rushes such material. Some parents feel that space cotton or cotton padding more comfortable, but it is not suitable for children to use a pillow. Baby pillow width is the baby's shoulder, parents can according to the specific circumstances of the child homemade baby pillow.

As the baby age increases, the baby pillow must change, not a pillow to sleep greatly, because the child's height and body in constant development, so the pillow can also be timely replacement.

The new supersedes the old. Baby relatively strong,baby shoes wholesale and most of the baby can have a calcium deficiency, calcium deficiency can also cause your baby easy to sweating, the new supersedes the old. Also can make the baby sweating, so baby pillow is often wet, if not timely drying or drying, inside the pillow will breed bacteria and mites, on the baby head health and respiratory tract there is a great threat to the health, so baby pillowcase, pillow to frequently change also should be in the sun, so it can sterilization.

On the market a lot of stereotypes pillow, look but not necessarily more practical, I still suggest that moms do yourself or ask the elderly help to the baby homemade baby pillow, such children will sleep more stable.

Replacement Remote

Friday, Apr 13, 2012 10:47AM / Members only

If you've got a replacement remote, or you're in the market for one, then you'll need to program it to work with all your devices. There's several different ways to do this, some of them are tedious, like entering in device codes, usually used on cheaper PC Remotes. Some ways are easier like with a learning remote, or some even have an internet set up wizard, but that's on most of the higher end (and higher priced remotes).

Universal Remote Programming by Code
Entering in device codes, is fairly easy to do, it can just take a long time. You basically look at a book that comes with your remote, and find the brand of the device you want to control. There will be several codes (I've seen as many as a dozen, give or take) of 3 to 5 digits. Five digits seems to be standard for most newer devices. You usually push a key combination for the device you want to control, wait until you see an indicator blink and put in the code. You then push the off button on the remote and if the device turns off, then the code worked, if not you start the process over with the next code.

Universal Learning Remotes
If that doesn't sound like fun to you then you can get a learning remote. It basically "learns" the codes from your old remote as you point it at the new one and push the buttons. Unfortunately if your old remote is broken or missing, then you'll have to do it with the codes. There are also some situations where the pulses from the old remote will be too fast for the new remote to read, in that case, you guessed it, you'll have to use the codes. Still, if it makes the process marginally easier then it's worth it. The prices on the universal remotes, are a little more expensive than the non learning ones, but you can still find them for under $20 on sale.

Computer Programming a Replacement Remote
If you're willing to spend a little more money, you could buy one of the lower end Logitech Harmony remotes, the Harmony 300 starts around $30, if you're willing to look around online. It only controls 4 devices but it does have a very cool way to set up your remote - through your computer. You connect the remote to your computer via a USB cable, then connect to the Logitech website. There is a wizard that allows you to enter your devices and it will set the remote up for you via the USB cable. Consumers report that you may have to tweak a few things if you have a complicated set up and lots of devices (in which case a 4 device remote probably won't work for you). Still, it's easier than the tedious trial and error code punching.
