What must I get? Why must I get? My friend bought LEDs for his boat and each of them died in the very first month, are each of them like that? Those are typical legitimate questions which our customers have asked. This article must apparent the air on the subject.
The confusion requires origin in the fact that all reduced voltage LED illumination products and services aren't built equal. There is a multitude of options for LED lights available on the market, almost no straightforward specialized data can be acquired on them and the cost range is very wide. The abundance of products and services and the lack of specific data has incited us to create this article. That document is based on data that comes right from the technicians and company of our product line and is accompanied by our own knowledge with LED Illumination in the Maritime Environment.
This article will attempt to spare you the physics behind the product while providing you enough data to cautiously choose what product you ought to mount in your vessel. I apologize to all or any the technicians who will not discover this document complete and specific, nevertheless the objective is to provide our other sailors with the essential understanding necessary to create a wise decision when getting LEDs because of their boat.
In the beginning, it'd seem to us that LEDs were created using a ship in mind. They've a great life span, don't brain vibrations, emit much less heat than their incandescent or halogen alternatives and use way less energy - of a eleventh of the electricity of a halogen - for an identical output. Therefore, where is ซุ้มตั้งพื้น the issue you ask? Why don't they work with my boat?
Traditionally, it had been simple. Along with output was BAD! Nobody loved the boring, low-output orange color of the early LED's. Effectively, that has changed and LEDs are in possession of an identical mild output and color compared to that of low-wattage halogens we discover on our boats.
The issue nowadays is different. The underwater setting using its different power options is very hostile towards electric components, specially LED lights. Voltage variations that individuals watch on our yachts are the maximum enemy of LEDs. Being VERY SENSITIVE TO VOLTAGE VARIATIONS, MOST LEDs located on the market are NOT SUITABLE for use on our boats.
I've offered not to find yourself in the physics of driving LEDs, but allow me to here is another several simple axioms that connect with LEDs. What uses doesn't involve sophisticated technology understanding, I'll contact this part BOAT LED 101.
All LED's are semiconductor diodes. They build their mild at the junction of their good and negative sides. When power is applied to an LED, the electrons leap in one side to another issuing mild in the proper execution of photons in the process. Various kinds of semiconductors produce various wavelengths and subsequently produce various mild colors. The warm white lights that individuals choose in yachts is created by Indium Gallium Nitride (InGaN). Include different products, like phosphors and you receive a satisfying incandescent mild color.
Today, what are the results whenever we apply voltage to the semiconductor is what we really should look at. Apply the proper voltage - inside our request 12V - and the proper level of current will travel through the semiconductor and we get a beautiful, energy-efficient, bright mild that will glow for a large number of hours. But, we want the proper voltage, properly 12V.
You and I understand for a well known fact that boats don't present research quality power! Begin the engine, the generator set or hook up to shore power and your setting has abruptly become hostile to your LEDs.
Why is that? Easy! When the generator, alternator or inverter sneakers in, we often start to see the voltage reaching upwards of 15V or higher. The higher the voltage, the more current experiences the semiconductor, the more electrons leap in one side to another, the more mild is made and MORE HEAT is generated. And, imagine what is the enemy number one of LEDs? HEAT! We need to both get a handle on the heat made or dissipate it. Apply lots of current to an LED and you will get a very bright mild for a really little while of time. Connect with small and you receive a dim, useless light. That's what occurred to you buddies'LEDs.
