Buying Light-emitting Diodes

Top-level product category: icon non-laser light sources

More specific product categories: fiber-coupled LEDs

Related product categories: superluminescent diodes, laser diodes

LEDs can be used as highly efficient light sources used for illumination, optical fiber communications, signal lights, and displays. They offer high efficiency, long lifespan, and versatility in various applications, ranging from consumer electronics to industrial and scientific uses.

Making Good Purchase Decisions

As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.

NEW: Structured Decision Process

Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.

Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

1. Understand the technical background

It is important to sufficiently understand the technology before buying.

Use the comprehensive learning resources of RP Photonics:

If you need personal help, contact RP Photonics to get technical consultancy.

I feel that I sufficiently understand the technical background.

2. Define your requirements

It is essential to fully understand and clearly define your requirements before you buy.

We recommend that you develop a list of clear specifications according to your specific needs, against which you can later check the suitability of found product offers:

To help you, we have already listed some aspects we recommend you consider when buying light-emitting diodes. Of course, there may be other aspects that are relevant to your specific case.

This list is for your own preparation, and can later (possibly in modified form) be used for quotation requests to suppliers.

I think that I am sufficiently informed about our requirements.

Otherwise, you will need to talk to your technical colleagues.

I consider the above list of specifications to be sufficiently complete, clear and accurate.

If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.

Insert these criteria when creating inquiry mails to suppliers with the buttons "Get quotation".

You find these buttons in the supplier list below or under "3. Find suitable suppliers".

3. Find suitable suppliers

We suggest three steps:

Below, you can find our list of suppliers for light-emitting diodes. Use the checkboxes to mark possibly suitable suppliers.
The selected suppliers will appear below this list, along with your list of specifications. You can then indicate which specifications they meet according to your research. (You should finalize your specifications before doing this.)
Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

Hamamatsu Photonics LEDs range from red to mid-infrared, a variety of wavelengths enabled by crystal growth and process technology that supports compound semiconductor materials. LEDs are mainly used in combination with photosensors, and offer a lower cost and longer service life compared to laser diodes. High quality and reliability are ensured by strictly controlled assembly and inspection processes.

The LS-HP1 works with the latest generation of high-power LEDs with up to 100 W power from an area of less than 15 mm². With the LS-HP1 series, we achieve outstanding luminance levels through optimized optical coupling into the liquid light guide without heating it up too much. The LS-HP1 is available for liquid light guides with core diameters of 3 or 5 mm.

There are versions with broadband white light emission and with quasi-monochromatic emission, available for different wavelengths.
