Waterproof LED light: How to choose it well?

It is essential for any HMI application to choose the LED with a luminous intensity that is compatible with its working environment: indeed, the state of the equipment must be readable / visible, and this, in any situation.
But light intensity isn't the only variable characteristic to consider in selecting the “perfect” light.

Short guide in the form of FAQ's:

Illumination intensity is the amount of visible light emitted in a given direction by the light source. It is measured in millicandella (mcd).
There are several variables to consider:
  • Indoor or outdoor use? Daylight is a very intense light source, even on cloudy days. Thus the intensity of the light must be much higher for it to be visible in broad daylight.
  • Distance: The intensity needed to see a near or far indicator light is very different. The light intensity must therefore increase with distance.
  • Colors: one, two, three colors or RGB field? it is important to keep in mind that blue or white light diffuses more easily. In contrast, red or green light is sharper.
  • The size of the light and its lens: this seems obvious, but it is important to remember that the size of the lens and its shape will define how the light will be diffused

In any event, the luminous intensity of the LED is an essential variable to take into consideration when choosing the indicator because it must make it possible to discern with precision the operating status of the application, but it can also reinforce the user confidence in applications where security is paramount.

For guaranteed visibility in all conditions - even in direct sunlight - Kynoppe offers the option of integratingHigh brightness LEDs.

To know the value of the luminous intensity of our indicators, refer to the technical data sheets.

Our lights are available in 3V, 6V, 12V, 24V, 110V or 220V power supply.

It is nevertheless important to respect the recommended loads because the LED is an electronic component particularly sensitive to voltage variations.

We therefore recommend thesystematic usea protection resistor to best adjust the supply voltage and prevent peaks from damaging the LED.

The materials used and the type of LED generally determine the operating temperature ranges of the LED.
The typical operating range of our LEDs is-40°C to +85°Cbut it is important to specify that this can be affected by the design and the working environment.

LEDs can connect to your circuit in 3 ways:
  • wire output: the LED is connected to the power source by wires which must be long enough to pass from the panel to the circuit board. Standard wire sizes will vary by product and can be customized to suit device design. The wire exit also ensures superior electrical sealing. Refer to datasheet or Kynoppe.com for lead wire information.
  • solder lugs: metal tabs are used to connect the indicator to the power source either by soldering wiring wires to it or by direct installation on the printed circuit. In some cases, the terminals can also accept quickconnect female terminals. Refer to the data sheet or on Kynoppe.com for the required technical information.
  • screw terminals: Screw clamp terminals are used to connect the LED to the circuit via wiring leads.

The lens is a "neck", or "sleeve" that envelops the LED. It can be used to protect the indicator from humidity and dust, or to improve the aesthetics of the design.

Its color and shape will directly impact the visual rendering of the indicator.

  • Concave shape: Used when device status privacy is required or visible only to the operator. Viewing angle less than 30°
  • Shaving shapee: Ideal when the status must be viewed directly, facing the LED with a viewing angle of between 30 and 45°
  • Protruding shape and bulb: Ideal for applications where the state of the device must be easily identifiable, even in peripheral vision. Viewing angle greater than 100°

Each design is unique. Thus, the Kynoppe range offers a wide range of mounting hole sizes to help customers design an attractive and efficient user interface.

Our drilling diameters range from6mm to 30mm, with the ability to create custom sizes to meet design specifications if the appropriate minimum order quantity is met.

Likewise, we offer aflatoptional when anti-rotation is required (MOQ 200 pcs).

Please refer to the product data sheet.

Yes, Kynoppe indicators are rugged enough to be used outdoors, but only when conditions match the IP rating of the product. Environmental factors such as temperature and humidity can affect equipment performance when indicators without the proper IP rating are used outdoors.
The entire Kynoppe range is at least IP65 and the majority of indicators are IP67 and therefore perfectly suitable for outdoor use.
 
Note
IP65- dustproof and protected against water projected by a nozzle.
IP67- dustproof and protected against full and strong water jets and waves.

Typical lamp life for each type of lighting technology is as follows:

  • LED: 40,000 to 100,000 hours
  • Neon: 25,000 hours
  • Incandescent: 1000 hours to 1500 hours

Variables that can negatively impact LED life:

  • Operating voltage
  • Operating temperature
  • Exposure to voltage spikes
  • Mechanical shocks and vibrations
  • Start and stop frequency

Of course the type of lamp used in the panel mount indicator will have an impact on the overall life of the indicator.

Since LEDs last on average133 times longerthan incandescent bulbs, they significantly reduce maintenance and operating costs over the lifetime of the fixture.This is why Kynoppe only offers indicators equipped with LEDs.

Our standard products can be adapted to specific needs but we can also start from scratch to design a solution that meets the mechanical, electrical, communication and aesthetic requirements of our customers. We have extensive expertise in design, prototyping, tooling, fabrication and assembly. Kynoppe is committed to providing the most effective and efficient solution for each application.
 
Our LEDs can be customized in a variety of ways to meet or exceed design requirements, including:
  • Custom Cable Harness:
  • Wire length, section and termination
  • LED brightness
  • LED viewing angle
  • Two-color and three-color indicators
  • Lens colors
  • Body finishes: Stainless steel, plastic, or anodized aluminum
  • Bezel styles - recessed, flush or prominent

The MOQ for a custom LED will depend on the order volume and the customization required for the design. Typically, a custom LED would require an order of at least 3,000 units. However, there are cases where the MOQ can be much less. Please feel free to contact us to discuss your specific design needs.
Our solution-oriented experts can work with you to design and manufacture exactly what you had in mind:sales@kynoppe.com

Depending on materials, application, size, features and customization, the typical cost range is1 to 6 € per unit.

However, LEDs with extensive customization and functionality can costmore than 20€ per unit.
Our team is available to work with you to find the solution with the most optimal functionality/cost ratio.
