Brief LED Module Primer
LEDs are rapidly replacing traditional light sources in applications where their unique characteristics can be best put to use such as their small size, low power consumption, low self-heating, high reliability, rapid on/off cycling or dimming capabilities, and they are resistant to shock and vibration. Some LED features can also be considered disadvantages depending on the application are the narrow viewing angle, near monochromatic light, limited wavelength selection, and they require a limiting resistor with a voltage drive.Grouping individual LEDs into modules that in turn can be grouped into larger assemblies to create high-output, flexible configuration lighting systems has revolutionized LED lighting by expanding the breadth of applications they can be adapted to. Let's get into Led modules a bit more:
What are LED modules?
LED modules typically are constructed of a series of surface-mount LEDs soldered to a copper circuit layer that is separated from the rigid base (frequently aluminum) by an electrically isolating, heat conductive dielectric material making for a very compact, durable light assembly. A dielectric is used to isolate the LED from the conductive base material because, in most cases, the back of the LED which is the heatsink area is often electrically connected to the LEDs anode or cathode. Generally, electrical interconnection is made via a removable wire connector soldered to the LED module's conductive copper layer or via wire leads. High-power LED modules, that is, LED modules made up of surface-mount LEDs with a power consumption of 1 watt or more, are the latest thing in lighting today.
What are the advantages of using LED modules?
LED modules, like the discrete LEDs they are made from, offer cool lighting with a very long life expectancy (10,000+ hours) as compared to traditional lighting like halogen bulbs. The sheer variety of available LEDs, their exceptionally small size, and the ability to widely vary the base layer shapes and sizes offers designers and engineers alike a degree of freedom when designing high-power LED modules and systems not typically available when working with more traditional lighting technologies.
Heat is a major LED module design consideration
Many people think of LED lighting as "cool" technology, both figuratively and literally and while the light output itself is thermally cool, the LED itself does, in fact, produce heat during normal operation although typically a lot less than a comparable light bulb. Color temperature-wise, LED output can be warm or cool depending on the LEDs used which is also another feature of their use over traditional lighting which tends to be warm, fluorescents excepted. 
All LEDs produce some amount of heat and some LEDs produce quite a bit of heat, especially true of today's high-power surface mount LEDs. Grouping today's hi-power LEDs together to increase a module's light output also increases the amount of heat that must be dealt with. Often in LED modules, the dielectric material used to insulate the conductive copper circuit layer from the aluminum base also helps to conduct heat from the back of the LEDs to the aluminum base which in these cases, acts as a heat sink. Active cooling of the base/heatsink may be employed depending on the amount of heat that must be conducted away from the heatsink. Heat management is a major concern when choosing the LEDs , dielectric properties, and base layer materials that go into LED modules.

LED modules may be configured in a myriad of shapes and sizes including pucks (circles), rectangles, squares, flexible strips, and more dictated by the types of LEDs used, the light output characteristics required (such as lumen output, beam width, etc%u2026), and the intended applications. Lenses, light pipes, and other optics may be employed on top of the LEDs to produce particular lighting effects depending on the application. Individual LED modules can be connected together along cable either as off the shelf system with precut cable lengths or in the field during installation with specific cable sizes between modules to create a very flexible custom system of lights. LED modules can also be built with flexible base layers instead of rigid aluminum, making bendable strips of high-powered LEDs capable of being utilized in a host of low-profile, high light output requirement applications such as architectural lighting, display lighting, accent lighting, or safety lighting.
