SEARCH INTERFACE INSTRUCTIONS AND INTRODUCTION

Each of these searches works independantly. Start where you like. Once you have performed an LED search for instance and then a different search, hitting the LED search will retrieve those results.
Once you have narrowed down your search and/or sorted your search by any results column you may dig down into more detail, find a datasheet and compare multiple results. Once on a product or company page you may return to the search you have performed by popping up the mini-searchs at the bottom of your browser window where hitting "search" will retrieve you last reults.
The searches have their own help buttons for your convenience.

LEDS

RATING - Lumens
The nominal lumens specified at current test and nominal conditions as listed in the product data sheet.

RATING - Power
The nominal input power rating as described by the supplier based on maximum current and voltage. (Watts)

COLOR
Choose White or Color. The default is "Any White" but the color slider allows you to choose the white color temperature in Kelvin. Similarly if you chose "Color" you can specify the color as a range of wavelengths in nanometers.

MAXIMUM DRIVE CURRENT
This is the specified maximum forward current fot the LED in otherwise nominal conditions. The default is "Unlimited".

MANUFACTURER
It may be useful, if a long list of products are returned to review them by manufacturer.
The default is ANY

ADVANCED SEARCH OPTIONS:

FOWARD VOLTAGE
The datasheet value of forward voltage at the test current in nominal conditions.

VIEWING ANGLE
You can further narrow your results if you have a particular viewing angle requirement. The slider contains all values found in the database but is not effected by other search criteria (you may return zero results)

DRIVERS/MODULES

DRIVER TYPE
If you are looking for a complete driver solution select "POWER SUPPLY" to search for modules. If you prefer a "driver IC" as the basis of your own driver design, choose "Diver IC". The default is "POWER SUPPLY"

VOLTAGE IN: AC/DC
The default is AC with no input voltage specified.
If AC input is choosen, select the input voltage range to your driver circuit if it is known.
If you have chosen a DC source you can pick the desired input voltage level with the slider up to 500V.
The search looks for driver circuits which can handle the voltage specified. i.e. within the maximum to minimum output voltage specified. Be aware that many driver ICs which do not integrate the power stage have no practical limit to the output voltage so they will all be returned by this search.

VOLTAGE OUTCalculated as the total voltage drop accress the chosen LED array. The default is "Any" and the maximum is 300V. Be aware that driver ICs which do not integrate the power stage have no practical limit to the output voltage so they will always be returned by this search.

OUTPUT CURRENT PER CHANNEL
The default is ANY and returns drivers fulfilling all the other conditions ignoring output current. Selecting the current output per channel will return all drivers capable of delivering this current (at least) under the other conditions specified. MANUFACTURER
It may be useful, if a long list of products are returned to review them by manufacturer.

ADVANCED OPTIONS:

NUMBER OF CHANNELS
Depending on the LED configuration it may be desirable to have multiple strings requiring either multiple drivers or drivers with multple outputs.

INTERNAL POWER STAGE REQUIRED
For ICs only, the device may not drive the constant current directly but require an external power stage (simple open source FET for instance). Selecting "YES" here returns only those driver ICs with direct drive capability.

DIMMABLE
Some devices have built in facilities for dimming which can be requested here. The types of dimming depend on the choice of DC/AC.

POWER FACTOR CORRECTION
Some devices have built in facilities for PFC which can be requested here.

OPTICS

TYPE
Restricted to lenses at the moment this will return the same result as the default ANY TYPE

-Works with-

LED MANUFACTURER
Is the manufacturer of the LED for which a suitable lens is being sought.

LED SERIES
This menu is modified depending on the manufacturer selected and allows the series for which a lens is being sought to be selected.

TOOLS

TYPE
Select the type of development tool you are looking for. The default ANY returns all types.

--Works With--
This is where you select the product type for which you seek a development tool. LEDs, DRIVERS are currently the other options.

BY MANUFACTURER
Once you have selected a product type you can specify the manufacturer of that product.

FOR SERIES
Once you have selected the product type, the manufacturer you can select the series for which you seek a development tool.

FOR SERIES EXAMPLE:
Choose FOR PRODUCT = "DRIVER" > FROM MANUFACTURER = "Texas Instruments" > FOR SERIES = "TL4242"
