Image Credit: StellarNet, Inc. | AUtomationdirect.com | D & N Electronics LED lamps are electric lights that use one or more arrays of light-emitting diodes (LEDs) as the source of light. LED lamps use an LED driver, a device similar to the ballast for a gas discharge lamp, to regulate the voltage and current powering the LED. Because LED packages and arrays are not standardized, the LED driver must be matched to the specific LED lamp. For any one LED, the color can be ultraviolet...

Design TrendsTop

Q:
What new technologies are influencing LED lamp design?
48 answers
Answers:
Hybrid uses(Green Energy and carbon footprint), Smart TV or screening units. The ability for an LED unit to be used for both viewing and sensing(light) makes it an interesting field to explore. Transparent TFT LED computer screens.
~Meiring P, Hobbiest, Ngodwana, South Africa
Electronic led drivers and controllers, the new o-leds, new semiconductor and phosphor formulas to gain efficiency and better color rendering index.
~Giovanni Z., Design Engineer, Bologna, Italy
Better heat sinks, more lumens per watt from the LEDs and the ability to run them at less that max and still produce adequate light.

Applications and UseTop

Q:
What are some of the applications you have used LED lamps for?
105 answers
Answers:
Described in "other". Used them to indicate with zeners and zener strings to indicate when desired voltage has been reached, as in charging energy storage caps. Also used with current transformers, with zener to indicate when an intended current has been reached.
~Paul N, Faculty/Staff, Deerfield, WI
Designing customized LED-lamps and controllers for large scale of architectural installations, decorative color controllable lights for events and production, wireless lights, inclusive battery and charging technology and RF network control and communications.
~Norbert Ernst, Manufacturer, Rüdesheim a.d. Nahe, Germany
Large format photographic enlargers. Location lighting, away from mains supply, where flash would be intrusive. Microscope illumination and retrofitting to a balance with optical readout.

Q:
Please share with us any “non-standard” applications that LED lamps have been used for.
33 answers
Answers:
Notifications e.g. vibrating LED's at restaurants, pocket lights. Solar options, toys, bouncing balls, etc, backlight illuminations of all kinds- tv's, monitors. Automotive industry.....brake lights, interior lighting, instrument panels, etc.
~Al S, 20years in lighting industry, Marketing/Sales, Mondovi, WI
Lighting in space sensitive home DB board as lighting (other than a bulky torch) and mains or trip illumination of board to work on or sight.
~Meiring P, Hobbiest, Ngodwana, South Africa
Illuminate the church tower with 6 degrees power led lighting, 15 meters away without significant loss of light in the sky, 4x 36W.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of LED lamps?
23 answers
Answers:
Buying low quality led lighting products for architectural installations which could cause significantly high cost for replacement If the outdoor protection is not enough or if components fail. The maintenance cost for lighting installations which can only be accessed with difficulties can be huge.
~Norbert Ernst, Manufacturer, Rüdesheim a.d. Nahe, Germany
- Lamps and modules are FRAGILE! handle with extreme care. - Use caution with modules and drivers - there are many types to choose from compatibility is an issue - Lamps installed in open fixtures outdoors WILL be subject to theft.
~Alex Ridley, Design Engineer, Corvallis, OR
No. But the improper encapsulation of lamp (remained acidity of encapsulant), containing the open emitter, can very quickly damage the emitting phosphor layer on the diode.

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
49 answers
Answers:
With the advances that I project we can see smart multi functional units operating in society. The wish list is that we will see smart parental control via either GAS laser LED similar to Microsoft XBox360's Kinect to sense who is watching now (additionally iris scan or finger print reading on a LED screen on the remote). Integration of green technology.
~Meiring P, Hobbiest, Ngodwana, South Africa
For engineers, architects and designers to embrace the benefits of LED. To get manufacturers to adhere to international standards and to get the large manufacturers in existing types of lighting to agree to wind down production of CFL's and Fluorescent tubes.
~Geoff M, Marketing/Sales, Brisbane, Australia
Curved PC boards, in the shape of part of a spherical surface. Large light transparent 2D surface covered in LEDs (say one metre square), (extension of strip idea) for general lighting, with adhesive backing.
~Peter H, Retired engineer, Brisbane, Queensland, Australia

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using LED lamps?
40 answers
Answers:
- Use well known brands not associated with China. I've had good experiences with: Phillips, Sylvania, Lithonia, Cooper, Juno. - Avoid T8 fluorescent retrofit lamps altogether. They don't perform well in fixtures designed for fluorescent lamps (LEDs are directional, fluorescent aren't). - buy 1 or 2 products to ensure desired CRI/CCT, output etc BEFORE buying in bulk!
~Alex Ridley, Design Engineer, Corvallis, OR
Led emitters cannot be used to light everything: like any other light source, they have to be used thinking to the quality of light, which is strictly related to the specific purpose we are asked to design a lamp for.
~Giovanni Z., Design Engineer, Bologna, Italy
Yes, check their quality and sales integrity. Do not swallow everything that is printed in supplier catalogs. Pay higher price to companies that are quality producers and gain their trust in your working together.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of LED lamps?
32 answers
Answers:
Led emitters are electronic components, not a different type of light bulb! So all usual precautions needed for that kind of device must be used, either designing lamps and installing them.
~Giovanni Z., Design Engineer, Bologna, Italy
Look at the beam angle projected to make sure it gives the spread required and make sure that you are aware of the color eg warm white, cool white, cold white, in relation to their Kelvins.
~Geoff M, Marketing/Sales, Brisbane, Australia
Know the light output and pattern desired. On design side would be overall package size, wide input driver with noise immunity, and keeping the heat to a minimum.
