Why Use LED Lights?

Posted by Bill Gors on 25th Feb 2015

A light-emitting diode (LED) is a semiconductor chip that emits light when conducting current and is a highly efficiant form of lighting.  LEDs are very versatile due to their ability to emit nearly all spectrums of light.  Many LEDs are rated to have over a 50,000 hours lifespan, in this same amount of time you will buy over 50 regular incandescent bulbs!  LED lights come in many different forms and are suitable for any application.

Selecting LEDs

To meet the specific needs of the RV industry, RV Lighting Inc. developed replacement bulbs for halogen on the cutting edge of technology.  To do this, we offer three specific technologies:

BASIC: The new generation of Eco-Led G4 is built with a LED driver and uses the constant current mode. This means that it keeps the bulbbrightness constant, no matter of voltage variation. An overvoltage protectionpreserves efficiency throughout its lifetime.

PWM: The Eco-Led G4 PWM uses the Pulse-Width Modulationtechnology in order to allow the use 12 volt light dimmer. This bulb can alsobe used to replace basic Eco-Led G4 in case of interference or noise on radioor TV.

ANA: This special Eco-Led G4 ANA was specifically created to be used with 2-intensity analog dimmer found in Newmar's Coach products.Exclusive of RV Lighting inc. this bulb's patent is currently pending(#L80006054US1). Input voltage 5-16 VDC.

Base Basics and What Those Terms Mean:

G4 – Pin style, halogen replacement,side mount

BG4 – Pin style, halogen replacement, back mount

GG4 – Pin style, halogen replacement, restrictive area back mount

WBU – Wedge bayonet, generally plugs into 921, BA15S or BA15D adapter base

BA15S – Single conductor base,(incandescent style 1156)

BA15D – Double conductor base,(incandescent style 1142)

921 – T15 Style wedge base

SMD: Surface Mount Device. A method for producing electronic circuits in which an electronic device is mounted or placed directly onto the surface of printed circuit boards (PCBs).

PCB: Printed Circuit Board.

Colors and Intensity:

The numbers you see such as 3528 and 5050 refer to the size of the chip. The older style strips that have been popular for a few years now are the sizes seen above. Currently, there are even smaller and more efficient LED chips on the market with the sizes of 2835, 3014, 5630, and 3020.Simply put, these LED chips are called SMD 5050 because the dimensions of the chips are 5.0mm x 5.0mm.

For Example: Item #G4-PWM-CW36, Cool White, Round PCB with36 SMD 3014 LED

Translates to:Halogen Type replacement bulb, round printed circuit board style,dimmable, with 36 Surface Mounted, 3.0mm x 1.4mm, cool white LEDs.

The way in which LED’s manage color change is all about the color temperature of the LED’s and how it is controlled. The chemical composition of the semiconductor determines the light color produced by the LED.The way you measure color temperature is by using a Kelvin scale. A Kelvin is a unit of measurement of temperature of light. Belowis a diagram showing the difference of cool and warm white by using a Kelvin scale.

Below you can see the variation of the colors.

As you can see above the color changes do varies, if you are looking for a standard ‘halogen style’ lighting effect for a general home we would advise the fitting of a Warm White led bulb this type of color is a more tranquil and welcoming.

If you would like more of a pure white more modern look, or displaying lighting where accurate color reproduction is important we would advise the cool white as the color is much cleaner.
