Custom LED Design
Traditional lighting technologies, such as CCFL (cold cathode florescent lamp), produce significant amounts of heat inside the LCD module. The amount of power to run the CCFL is necessarily very high in order to generate the strike voltage in the CCFL tube. This is not an efficient technology, and the inverter—required to create the high voltage needed to run the CCFL backlight—is typically a source of EMI noise.
LED bars are a more suitable form of lighting in most rugged environments, and for many reasons: they are extremely durable (and do not contain parts that can shatter or break), very efficient, and produce less heat when compared to other forms of lighting. LED lighting not only generates less heat, but also dissipates it in a very specific direction; rather than releasing it into the surrounding air, an LED lighting device will direct most of the heat backwards into the circuit board onto which the LED is mounted. This characteristic becomes invaluable in designing and developing rugged LED backlight systems used in our display systems. Although all heat must eventually dissipate, very little of it will be located directly in front of the LED lens. TVD high bright LED backlight systems use a rugged and reliable heat sink that transports thermal energy away from critical areas altogether, increasing the effective life of the lighting system in application.
