LED Production in China
Because of their large workforce and production-based economy, there are a wide variety of LED lights China manufacturers make for the international market. Since LEDs are small and easy to produce and ship worldwide, China LED lights find their way into everything from car LED lights, to appliances, to regular bulbs. Read more »
LEDs and the Environment
A lot of people vaguely understand why a bulb Led is better for the environment than an incandescent bulb, but not many really see the quantifiable differences between the two. Yes, LEDs require less energy, but why? Incandescents blow out more quickly, but why? Is it possible to make an incandescent bulb that lasts as long as an LED? Read more »
Decorating with LEDs
Up until recently, LED technology wasn’t really considered “decorative.” Sure, a power LED could find its way into a stop light, or a circuit board, or a flashlight, but their harsh, bright light wasn’t very adaptable for home use. Since people tend to prefer softer mood lighting, this meant that you would be very hard pressed to find a MR11 LED in someone’s living room. Read more »
The Many Uses for LED Bulbs
A lot of people hear “light emitting diode,” and think of those tiny, annoyingly bright points of light you see used for computers and other technological applications, SMD LEDs. The fact is, however, that power LED technology has come a very long way from those little diodes. Now, it’s possible to find a bulb LED to fit just about every application in your home, from task lights to mood lighting. Read more »
LEDs and Electronics
A LED diode is a cheap, easy way to indicate the status of an appliance or a piece of electronics. In many cases, they are soldered to circuit boards and other items to indicate when components are powered, on standby, or malfunctioning. Read more »
Fun Projects With LEDs
Though LED technology is usually looked at as a necessity for safety, electronics, or other practical concerns, there are a number of hobby kits that use LED lighting. Gardeners, electrical hobbyists, and model builders all use LEDs regularly. Read more »
LEDs and Safety
A LED diode isn’t commonly thought of as a piece of safety equipment, but the fact is that their very nature makes them ideal for the task. Because SMD LEDs are tiny and can be easily soldered to just about anything, they are ideal as warning lights to tell users when a piece of equipment is on. Read more »
Saving Money on LEDs
LED technology is highly desirable for people who want to save energy, but a lot of LED lighting options for home use are still pretty expensive. You can get a multi-pack of regular incandescent bulbs for as little as two dollars, but getting a nice, dimmable LED for mood lighting can run you fifty dollars or more! Fortunately, it is possible to save money on LEDs, with some creativity. Read more »
Here Are Some Important Answers To Your Questions About Led Lighting And Enery Savings

Lizzie asks…
HDTV should a consumer wait for the new tech soon to arrive?
Hello, I was wondering as to what a consumer should do now that new HDTV technology such as the laser and OLED TVs are soon to arrive. I saw Sony 27″ tv with a 1Meg:1 Contrast ratio and Mitsubishi’s Laser TV technology which according to an article will be released at the end of this year. According to the article this new tech could replace plasmas and LCDs. I know the price might be high for this new tech but I would like to get some input on this issue. Thank you.
ledtech answers:
I think you should not wait for a better technology only if what you have now is worth scrap and not useful at all

Sharon asks…
when will OLED tvs be sold?
i wanna buy atv but im not sure if i should wait for OLED or just go with a plasma or lcd
ledtech answers:
They’re being sold now but are very expensive. $2500 for this small one from Sony. It’s be a few years until the price comes down on these but the technology is advancing pretty rapidly for OLEDs. When they do come out in mass quanities, they’re going to be worth it. For now stick with the LCD or plasma. Plasmas are starting to become scares though. They used to be the choice for larger screens but the companies have eliminated the cons of LCDs and have made them a better buy. Wait until the Thanksgiving day sales. You should be able to find good deals on LCDs.

Paul asks…
What are these OLED TVs?
I heard that they’re super thin, and that you can fold them? Is that true?
And when will they be released?
ledtech answers:
You heard correctly. An OLED display can be draped over a chair, for example, but currently they are mounted inside ultra thin TV sets.
I wouldn’t count on getting one any time soon–if it comes to market at all.
The big problem is that it’s currently very hard to make OLED TVs in large sizes; for instance, the largest OLED display Sony at the Consumer Electronics Show was 27 inches. Also, manufacturers are still experimenting with the display’s organic materials to increase the lifespan to the point where OLED panels’ lifespan would be competitive to that of plasma’s.
There was a small screen model introduced this year. An 11″ Sony for $2,500 but it is no longer in consumer production due to the lack of demand. Http://www.google.com/products/catalog?q=oled+television&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&cid=7457040179251382059&ei=s-88TLqqAYzA8ATTwan9DA&sa=X&oi=product_catalog_result&ct=result&resnum=3&ved=0CC4Q8wIwAg#
There are patent problems that are also held back production of these sets. Apparently Kodak holds patents on some of the technologies used in OLED, and that means any other TV manufacturer who builds these sets must pay Kodak for using the technologies.
I wouldn’t say that this technology is necessarily dead, but Sony’s poor financial performance at the time will likely signal an end to the production of future OLED TVs. Other manufacturers, such as Samsung and LG, have demoed their own OLED TVs at trade shows. But, like Sony, these companies have bumped into the challenge of mass producing such sets. So none of the announced products has actually hit the market.
Sony’s exit from the technology could be the nail in the coffin for OLED TV, at least for now, as companies look to other less costly innovations such as 3D TVs and LED backlit LCDs.

Thomas asks…

Lisa asks…
Where can i find LED lighting for my home?
I am remodeling my home and would like to use led lighting in as many places as possible but it seems like the only led lighting available at this time is just accent lighting.Does anyone know of a website that has LED lighting for the home as a main source?
ledtech answers:
Led lighting is used a lot here in england what you can do is use replacement led bulbs for common down lighter etc
But remember it can be difficult and expensive to dim led bulbs as this either requires special led drivers light switches or bulbs (or the use of dummy loads which negate the power saving )

Richard asks…
Can I use LED light bulb on my 3-way lighting fixture?
I know there is no 3-way LED bulb yet. My 3-way light fixture can be set to use 50, 100 or 150 watts. Can I replace the old bulb with LED bulb and keep the setting on 50 watts permanently? The LED light bulb actually just consumes 6 watts in this case.
ledtech answers:
You’re right, 3-way led bulbs are not available. Yet. But they will be soon.
If you buy a 50 watt equivalent led bulb, it will work in your 3-way fixture. The only problem will be that you’ll have to turn (or pull) the switch twice to turn it on and twice to turn it off.

Carol asks…
Would motion detector technology work with LED street-lighting?
Leaving the issue of safety aside, would it be cost efficient to have LED street-lights “turn-on” only when motion is detected ?
Or would there be some problem with there being frequently repeating cycles—too many “offs and ons”? If feasible, would savings be significant, over, say—LED without motion detection?

Ken asks…
Get Table Names from Oracle Database?
I have a code I found which is attempting to get the name of all of the tables in a database. When I debug the code, it’s giving me an error at conn.ConnectionString = strCn stating:
An OLE DB Provider was not specified in the ConnectionString. An example would be, ‘Provider=SQLOLEDB;’.
Below is the code:
Shared Sub getConnection()
Dim strCn As String
Dim StrDataSource = myDataSourcesName
strCn = “Data Source=strDataSource;Persist Security Info=True;User ID=myID;Password=myPW;”
Dim conn As New OleDb.OleDbConnection()
conn.ConnectionString = strCn
conn.Open()
Dim schemaTable As DataTable = conn.GetOleDbSchemaTable(OleDb.OleDbSchemaGuid.Tables, New Object() {Nothing, Nothing, Nothing, “TABLE”})
Form1.DataGridView1.DataSource = schemaTable
conn.Close()
End Sub
What’s the best way to resolve this?
ledtech answers:
Well first of all, you need to install the oracle client for visual studio, ODTwithODAC. Then you have to add a reference to Oracle.DataAccess.Client
Then with intellisense, you will have an Oracle set of connection, command and data adapters.
You must use the Oracle .net objects.

Help with adding record to database in Visual Basic?
I am trying to add a record to an Access Database in Visual Basic.
I don’t want to use DataSets, I want to write my own SQL queries when possible, here is what I have:
Dim connection As New OleDbConnection(“Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|assets.mdb;mode=read|write”)
Dim insertCommand As New OleDbCommand(“INSERT INTO asset VALUES (‘test1′, ‘test2′, ‘test3′, test4′)”, connection)
Try
connection.Open()
MsgBox(“Connection Opened”)
insertCommand.ExecuteNonQuery()
MsgBox(“query executed”)
Catch ex As Exception
MessageBox.Show(ex.ToString())
Finally
connection.close()
End Try
That code executes fine, but nothing gets written to the database. I would really appreciate any help, for some reason I just can’t figure this out.
Thats not it. When I run this function, it seems to work. When I try and run in again, I even get an error saying that it cant be executed because it would create a duplicate entry. However, like I said before, nothing actually gets written to the database.
ledtech answers:
Try specifying the columns you’re inserting into in your command statement.
Insert into tableName (column1,column2,column3) Values (‘Value1′,’Value2′,’Value3′)
does your table have a unique field? Try making a field with an autonumber, you wouldn’t need to send values to it, it just keeps from making duplicated entries.

ledtech answers:
If you wish to get the row you selected from the grid, GridView.SelectedRow or GridView.Rows(GridView.SelectedIndex) should be the way to go.
To remove the row, I believe reloading the data is the easier way to go. Simply get the data from your database again after the deletion.
Hope this helps.

Maria asks…
My computer turns on for a second and then shuts off?
My dad’s friend (who is fairly knowledgeable with computers) installed a 1 Tb hard drive into my custom tower (because I am not very learned in how computer parts work), and when I hooked everything up in and booted the computer up, it worked fine, I had a 120 Gb external drive plugged in at the time and I when I ran the OS disc (Ubuntu), it indicated that only the external drive was recognized. Next, I pressed the power button, and then the computer did not shut off right away, so I went onto the computer and pressed the shut down button on the Ubuntu desktop screen that was up. Next, the computer went to a black boot-up looking screen, ejected the disc and when I took the disc out and closed the drive it shut off. SO…I opened the tower back up and found out that the SATA cable had never even been connected to the hard drive. I plugged the cable into the hard drive and closed her back up, I tried booting it and it wouldn’t turn on. All it does is occasionally turn on for a second (indicated by the fan and led in the fan as well as a red power light on top of the tower). Also there is an amber light glowing inside the computer, which I assume is to show that the computer is getting power, but I have no clue why this thing won’t turn on anymore. Any suggestions/solutions for this problem?
ledtech answers:
This problem, usually if you get a warning Beep first, is caused by CPU overheating. Possibly the heatsink/fan combo got disturbed during the hard drive change. Not connecting that SATA cable shows a certain amount of incompetence by the way.

V2 electronic cigarette battery problem.?
I’ve had my V2 electronic cigarette for about two weeks, and didn’t have a problem with it. Yesterday the battery ran out, so I plugged it in, and left it there for a while. The light on the charger lit up green, so I left it there for a while. After about four hours or so I noticed the light was still green, but I unplugged it anyway. I screwed on the carto and took a drag, but the LED on the battery flashed 15 times, and it emitted no vapor. I unscrewed the carto and took a drag out of the battery by itself, and it worked perfectly. I tried it again with the cartomizer, and it just flashed 15 times again. I looked up some solutions online, and found that the way to reset the battery is by blowing hard into it without a carto five times. I did this, and the LED lit up for a bit, then flashed and turned off. I tried it with the carto once more, but it flashed 15 times once again. I tried without the carto, and it works perfectly. I even tried every carto that I had left and nothing! I tried calling Customer Support but it said something about the system being down, and calling on Monday. Can any of you help me out with this, or will I have to wait till CS is back up? I don’t have any money to buy analog cigarettes, and I don’t think I can go a full day without my ecig. I already didn’t sleep at all last night. Please help!

Help with HP Notebook Black screen?
Hello, I am having a issue with my Hp G60-630US notebook and I am at a lost at how to solve it. The problem started about two weeks ago during a party. My laptop was dropped I picked it up and everything seemed fine, then the next day when I turned it on I found myself staring at a black screen no POST, no Bios, but the led lights ,the back-light ,the hdd indicator , fan, and dvd drive were working . At first I figured it may just be an error so I restarted it but unfortunately nothing changed. Being partially computer savvy and a bit desperate I began to scour the internet seeking a resolution.So I happened upon a few forums describing possible solutions, but nothing so far has worked. Before I go out and spend money on replacement parts and such I’d at least like to narrow down the issue.
Things I’ve Tried:
1. Removing Battery and power cord, holding power button for 30-60 seconds.
2. Powering Laptop on with Lcd screen at an angle
3. Removing and re-seating RAM and Hard-drive ( The latter of which caused the backlight and hdd indicator to stop functioning)
4. Holding down fn +f4 while powering on
Please help me with this dilemma, any assistance will be greatly appreciated as I don’t have the finances currently to afford a new laptop.
ledtech answers:
Restart your computer. After you pressed the power button to restart. Keep on tapping F8 key on the keyboard on and off.
Boot advanced option will show up on the screen. You may boot your computer to the following option. A. Last known good configuration stillness b. Safe mode with Networking.
If Safe mode w/networking works, restore your computer to an earlier using the system restore features.

LED monitor display problem?
I have an LED monitor(LG-22 inch).I am using it as desktop monitor.Now there is a problem.When I switch on my computer,the whole system runs as usual,except the monitor.The red light just blinks and screen shows LG logo,but the display is not coming.The power supply is ok.What could be the problem?
Please suggest a solution?
THANK YOU
ledtech answers:
First off, is your computer actually completely booting? If it is just making “I am on” noises, it may not have sufficient power from the PSU to support the graphics card running at such a high resolution.
Second, if your graphics card has two connectors, ensure that the monitor is plugged into the primary, which is usually the left-hand side (when looking at the back of the computer).
Third, check that the monitor knows which input to display. Without knowing the exact model, I can’t rule out whether or not it is one that comes with more than one input.
Good luck.

Helen asks…
Why is IE6 preventing script execution when modifying an Access Database?
Here’s the issue, I’m using Dreamweaver MX 2004 and can connect to the database no problem but executing a sqlString to connect and add a record through IE6 and other browsers is for some reason being stopped. I get no errors what so ever but the DB is not modified as it should. In fact it seems that all database stuff I have in both ASP.NET and ASP 3.0 are not working properly when viewing it in the browser.
Nothing has changed as far as Dreamweaver goes as far as I can see and as I said there is not problem making the connection to the DB with the site whether it’s DNS (less) or OLEDB but when testing it, it’s just not working, and it should.
Any web developers out there have an idea of what’s happening? I’m on WIN XP Pro, SP2, Dreamweaver MX 2004.
I’m ruinning on IIS 5, when I say the database stuff isn’t working where it was before I mean that it seems that some of the scripts in the page, particularly ASP.NET aren’t executing. I enabled write permisions on the database, even the entire folder but got the same result which is no result. Again, no script error message, nothing to tell me there was a problem with executing or writting to the database.
ledtech answers:
If you can connect to the database in Dreamweaver, try connecting to it with Access and see if you can modify a table or execute a query. It’s either a permissions issue with your database file, a permissions issue with the webserver that the file is on, or something quirky. I’d suggest turning off Friendly error messages in IE 6 so it can (hopefully) give you some good feedback.
I’m a bit confused when you say “seems that all database stuff… Are not working properly when viewing”. So none of your select statements are returning values either? Seems like a config issue.

ledtech answers:
Just modify the connectstring and reset the control to the new string, then open it up. Same with the report file. You can load reports into the control just by changing the report parameter. In the worst case scenario you can always create a new control, configure and replace the old one.

Can you post the SQL query that it is trying to execute? Crystal is never the fastest thing on the planet, but a bad sql query can make performance horrible. Also, is your database normalized. The app may perform fine, but when doing large queries it has to do many table scans.
