The light emitting diode is such a fantastic piece of technology, but when you need lights which are bright enough for use in automotive forward lighting, heat is always a challenge. Much like your computer, phone or tablet, LED's are based on semiconductor technology and if they get too hot, they will either fail or performance will suffer greatly. The SolarFlex LED kit uses some unique heat management techniques to deliver over 1850 lumens of light per bulb in a package that will easily fit in almost any vehicle. Typically LED bulbs producing this much light require large, bulky aluminum heat sinks which take up space and often are not compatible with many vehicles.

The optical pickup in the Philips/Lite-on DS-8A8SH CD/DVD RW drive is virtually identical to the one in the Panasonic UJ8D1. It wasn't even worth putting together a composite photo as the overall appearance is so similar. But see Optical Paths of Philips/Lite-on DS-8A8SH CD/DVD RW Drive. Can you find the differences? ;-) In fact, this pickup may simply be an updated version of the same design.

Now, what you've all been waiting for: Info on the PS3 Blu-ray optical deck.

Sony KES-400AAA CD/DVD/Blu-ray Optical Deck shows the overall unit found in the PS3, while Sony KES-400A CD/DVD/Blu-ray Optical Block View 1 and Sony KES-400A CD/DVD/Blu-ray Optical Block View 2 are additional closeups of the of this very complex optical assembly (with the bottom covers removed). (Note that the laser diode is not present in these photos.) I would seem that having totally separate optical paths for the CD/DVD and Blu-ray functions would be simpler and cheaper than what is done in this Sony unit. Having to use common optics for everything means more compromises and more expensive coatings and optical design.
For many photos and a detailed description and analysis of the laser/optics assembly, extraction and powering of the tri-wavelength laser diode, and much more related to the optical pickup for a PlayStation 3, go to Leslie's Dissection of a Blu-ray Reader Assembly Page or Sam's Copy of Leslie's Dissection of a Blu-ray Reader Assembly Page. The photos there iuclude high resolution versions of some of those above as well as for the HD-DVD drive described below. The sophistication of the technology and what's crammed into an itty-bitty space is absolutely amazing. Compare its complexity to the PS2 PVR-802W, above!

The Blu-ray Disc Format White Paper: Key Technologies has some interesting information on technical issues relating to implementation of multi-format optical blocks including the triple wavelength laser diode. There is much information more under "Technical" at the Blu-ray Disc Association Web site.

Here are photos of a different Blu-ray picksup. SF-AW210 Blu-ray Optical Pickup - Exploded View with Annotation is a totally different design, with dual lenses a few mystery optics, but apparently no zoom lens. :) (Photo courtesy of Karol Luszcz.)
And next, a pickups for HD-DVD. Actually, the first optical block is probably suitable for both HD-DVD and Blu-ray. There is some printing on the main PCB visible in the photo of the top of the device that reads: BD/HDP - the "BD" is likely for Blu-ray Disc. Also, the Wicked Lasers Sonar violet laser pointer uses the laser diode from what appears to be the identical pickup as seen in Sonar Blu-ray Laser: How They Make It - Gizmodo. I labeled it HD-DVD simply because I was originally told it came from an HD-DVD device.

This CD/DVD/HD-DVD Optical Block 1 has totally separate beam paths for HD-DVD and CD/DVD. The HD-DVD (violet) laser diode would go on the right feeding into the Polarizing Beam Splitter (PBS, the cube), then a collimating lens, and turning mirror feeding one objective lens. (As with the Blu-ray optical block, above, the actual laser diode is missing.) The top exit of the PBS is from the violet LD and may be some kind of beam quality monitor - it's got way more connections than needed for a simple power monitor. But that is also required as the violet LD has no internal power monitor, which would suggest that the optical block is actually from an HD-DVD or Blu-ray recorder/writer since higher power LDs often don't have internal monitor photodiodes. The bottom exit of the PBS is for the HD-DVD photodiode array. The CD (IR) and DVD (red) combined hologram laser diodes with diffraction gratings and photodiode arrays is under the copper bracket on the left feeding only a fixed collimating lens and turning mirror to the other objective lens.
Also note the servo-controlled collimating lens in the HD-DVD beam path. This is also present on the Blu-ray pickup and the next HD-DVD pickup, below.

The HD-DVD/DVD/CD Optical Pickup from Toshiba HD-A3 Player is another example. It's also a dual lens pickup but with conventional laser diodes and a somewhat simpler organization.
The Toshiba PHR-803T HD-DVD/DVD/CD Optical Pickup is apparently used in the first generation Xbox HD-DVD drive, though the ones I have are from PC HD-DVD ROM drives labeled: SD-H802A. Toshiba PHR-803T HD-DVD/DVD/CD Optical Pickup - Exploded View with Annotation shows the details and Toshiba PHR-803T HD-DVD/DVD/CD Optical Pickup - Closeup of 405 nm Laser Diode is a truly spectacular view inside. (These two Photos courtesy of Karol Luszcz.)
This pickup is so much simpler than any of the other similar 3 or more format designs. There is a violet LD for HD-DVD and a combined 780 nm and 650 nm diode for CD and DVD. Each is in a 5.6 mm can. There appears to be a separate photodiode for optical power monitoring, at least for the CD/DVD LD as there are not enough pins. The two LDs are combined in a beam-splitter and after that, their optical paths are identical with only a single objective lens. A beam-splitter plate separates the outgoing and reading beams and there is only a single PD array chip. All the other optical elements are similar to those in a CD or DVD pickup with the exception of an LCD wavefront corrector below the objective lens. This pikcup uses the normal 3-beam tracking with separate diffraction gratings in front of each LD's output. The only other optics are a cylindrical lens (probably cylindrical for focusing, though it may do other stuff) in front of the PD array, and a collimating lens below the LCD.

The relative simplicity makes sense though since it doesn't need to support the Blu-Ray (BD) format. BD has much more major differences than HD-DVD compared with CD and DVD. In particular, the NA of the lens is much lower (0.65 compared to 0.85) and the cover layer on the disc is thinner (0.1 mm compared to 0.6 mm). That is probably the reason there is no stepper motor controlled lens in this unit.

Upon power up, the unit first attempts to read a DVD, then a CD, and only then turns on the violet diode to read the HD-DVD. If it finds one, then that diode will remain on for a minute or so unless the drive is actually accessed. It's hard to determine the actual power being used for the violet diode, but it doesn't look like it is very high. The red DVD power is almost certainly running under 5 mW.

The montage photos show what it looks like in situ when reading a DVD with the red (650 nm) laser diode and an HD-DVD with the violet (405 nm) laser diode. My digital camera refuses to reproduce a decent violet! :) I was unable to capture the similar IR (780 nm) when reading a CD but it would have the same beam path as for the DVD.

The Toshiba DRO-811 HD-DVD/DVD/CD Optical Pickup is very similar and possibly even a bit simpler.
Components of the optical pickup

All the parts described below are in the optical pickup. As noted, the optical pickup is usually a self contained and replaceable subassembly. The actual complement and arrangement of parts depends on the specific pickup design - a number of popular variations on the basic arrangement are used. Thus, should you actually end up dismantling a dead optical pickup, it will probably not match this description exactly. While the relatively old Sony KSS110C Optical Pickup has most of the same components as described below, the very common newer Sony and Sanyo optical pickups combine multiple functions into fewer elements. Typical examples are found in the Sony KSS361A Optical Pickup and Sanyo K38N Optical Pickup. The even simpler CMKS-81X Optical Pickup and Optical Pickup from Philips PCA80SC CDROM combine the laser diode and photodiode array into single package and eliminate all of the other optical components except for the diffraction grating and turning mirror (and the latter could be eliminated where space permits below the deck). The resulting designs are much cheaper to manufacture, more robust and reliable, and should have better performance as well since there are fewer intermediate optical components to degrade the beam.
Also see the section: CD optical pickup operating principles.

Most expensive replacement part of the century award

This is right up there with $400 hammers and $20,000 toilet seats :-)
MCM Catalog #38, page 500: Original Aiwa/Sony Spindle Assembly: $94.50(ea). It is part number 32-7275 if you are eager to order one ;-).

From the picture, this is the type of spindle assembly used in the typical $70 portable CD player or cheap (by now obsolete) CDROM drive - a $1.99 Mabuchi style motor (two pin connector included!) and plastic self locking spindle platter glued or pressed to the shaft.

Do people actual pay this???? Why would anyone spend almost $100 for one of these replacements?

Yes, I know most of the answers. The question is to stimulate discussion.

Comments on Sony KSS pickup suspension problems

There seems to be some debate as to what extent weak suspension contribute to uncorrectable (by the internal adjustments) skipping and other erratic behavior. However, it is generally agreed among those who actually have to repair CD players and CDROM drives using Sony KSS pickups that such deteriorated suspensions can indeed be a cause of a variety of problems.

Despite its being a precision optomechanical device, optical pickups are remarkably robust in terms of susceptibility to mechanical damage.

Laser Diode - This is Infra Red (IR) emitting usually at 780 nm - near IR, just outside the visible range of 400-700 nm. The power output is no more than a few milliwatts though this gets reduced to 0.25-1.2 mW at the output of the objective lens. A photodiode inside the laser diode case monitors optical power directly and is used in a feedback loop to maintain laser output at a constant and extremely stable value.
The photos below show some of the types of laser diodes you may encounter in CD players, CDROM drives, laser printers, and bar code scanners:

A Variety of Small Laser Diodes (CD, laser printer, bar code scanner).
Closeup of Typical Laser Diode (from a laser printer).
Closeup of Laser Diode from the Sony KSS361A Optical Pickup (seen 'actual size' in the upper left corner of the group photo, above.)
On an increasing number of pickups, the laser diode and photodiode array are combined into a single package. These are recognizable by their 8 or 10 lead package. See the section: Optical pickup complexity.

Product Details
Flexible Light Guides for SMD LEDs
This family of flexible light pipes, from MENTOR, consist of a housing, light pipe and lens. Flexible light pipes offer an alternative to rigid light pipes where flexibility in design is required. They can be mounted to the PCB for use as a horizontal or vertical light guide. Available in a range of length options, the flexible light pipes have a round head. The pipes are fixed onto a PCB by two press-in lugs in the housing, offering an easy set-up process.
Flexible light pipes are designed for use with surface mount (SMD) TOPLED LEDs. The light pipe inject face sits in close proximity to the LED on the board.
Features of the flexible light guides:
Round heads
Lens: PC clear UL94
Light pipe: PMMA
Housing: PC black UL94
Ambient temperature: -40°C to +85°C
LED Light Pipes, MENTOR - Flexible
MENTOR light guides are designed to transmit light from a PCB-mounted LED to the desired user interface. This transfer is completed with little or no loss of luminance and no light bleed between adjacent elements.
The flexible LEDs push-fit into a plastic housing which is mounted onto the PCB. They have a round head shape in a range of diameters.

By popular demand, we now have a project tutorial for how to make your own programmable, ultra-blinky LED belt. Perfect for parties, raves, parades, weddings, funerals, and bar mitzvahs. Wear it with pride, wear it with blinky! Follow this tutorial to build your own heirloom LED belt, and hand it down to your grandkids.

We designed this project to demonstrate how to use the digital LED strip, how to use our Atmega32u4 breakout board with the Arduino IDE and how to make a portable battery powered project that runs off of AAs. This project is not too difficult, and can be finished in a day. Some soldering experience is good since 'free wire' soldering is a little more difficult than soldering to a PCB, but even beginners should be able to manage. We don't include a tutorial on using the Arduino IDE so its good if you've played around with the Arduino already.
