The Role of Drivers in an LED Lamp

Lighting Emitting Diodes, or LEDs are negative impedance devices. This means that unless controlled, the current supply to it would continue to increase, causing the lamp to fail almost instantly after starting. For this reason, a driver, which is acurrent-limiting device, must be used with every LED lamp. The driver serves three functions:

(a) It provides the proper starting voltage to establish the correct light up process b) Second, the driver supplies the proper voltage to operate the LEDs.

(b) Third, the driver limits the operating LED current and voltage to a preprogrammed level prescribed by the lamp manufacturer for the optimal operation of the particular type of lamp being used.

As a result, it is very important that the driver used always be matched to the particular lamp type, wattage, and line voltage being used. If the incorrect driver is used, incorrect voltage and current shall be supplied to the LED chips, which shall instantaneously destroy the device.

The Role of Drivers in an LED Lamp

A traditional LED driver consists of a combination of resistors, capacitors, and diodes that work collectively in circuit to power a series of LEDs.

Given the number of closely packed components carrying electricity through them, a heating effect is created by the LED driver.


The Effects of heat on a Lamp

The light emitting diode is silicon based material that is highly sensitive to heat. Thus, irrespective of the quality of the LED chip, the introduction of heat directly impacts the performance of the LED and has the following side effects:

  • Loss of lumens per watt
  • High depreciation rate of lumens
  • Discolorization of the LED chips over time
  • Flickering of the LED lamp
  • Reduced lifespan

As a result of this, most LED tubes in the market place today have relativity low efficacy rates (less than 100 lumens per watt) and lifespans of less than 50,000 hours. It has thus been challenging to find an LED tube that directly replaces a fluorescent tube with the equivalent brightness found in common applications.

Some manufacturers have managed to achieve higher lumens per watt by separating the driver unit from the actual LED tube. This installation however, is timely and costly as it involves removing the fluorescent ballast from the fixture and reconnecting the LED Driver in its place. Even so, these tubes still do not produce enough lumens to directly replace a fluorescent lamp.


ThinkLite’s Proprietary Driverless Technology

At ThinkLite, we are committed to long-term success and to the highest integrity in our product. Over the past four years we have worked closely with industry experts to develop, design, manufacture and patent a permanent solution to this issue with LED lamp technologies.

Combining expertise from research partners in Germany, and at the development laboratories at Samsung, Inc. in Seoul, Korea,ThinkLite has developed an LED driving technology that reduces the average number of components in a driver from 156 to 4 pieces and seals the driver into a tiny microchip, called the AIC (Alternating Integrated Circuit).


ThinkLite is the first and only company in the world, that has been able to design and bring to market, this technology of entirely eliminating the driver unit for a linear tube application.

This microchip is simply placed at the end of the same PCB board on which the LEDs are mounted, and thus eliminates the need for the hollow spacing inside the tube.


Advantage of ThinkLite Technology

Due to the fewer components and moving parts present in the  AIC microchip, the heat emitted from the lamp is reduced by 90% when compared to any other driver-based LED system. The most common cause of failure in a LED lamp is excess heat. Due to the diminished heat generated by ThinkLite LED’s the system can

  • Provide the high Lumen / Watt efficacy (180 lumens per watt)
  • Minimal Depreciation of Lumens over time (5% depreciation over 5 years)
  • Elimination of flickering of the LED lamp
  • Increased lifespan of 65,000 hours
  • Allowed for more surface area for an enhanced thermal management system for the LED T8
  • While meeting all UL, CE, FCC and DLC certification and safety requirements


Traditional LED Driver,

that acts as a ballast to the LEDs

  • The traditional LED driver consists of 156 different components working together in a circuit, of which most of them are tiny resistors
  • The introduction of every component in the design increases the chances of the circuit to break off; and thus, causing the lamp to fail.
  • The large number of components creates more heat, which:
  • Limits the light that can be produced
  • Increases lumen depreciation
  • Reduces the lifespan of the system
  • Operating temperature: -22°F to +95°F
  • And lastly, this design is more expensive to produces, yet highly inefficient.

ThinkLite AIC Chip and PCB board now “drives” the LEDs

  • ThinkLite has reduced the number of components in the circuit to only 4 units, and have compressed it into a single microchip, called the AIC.
  • As a result of this technology, less heat is now created in the system, allowing us to:
  • Produce significantly more light per watt
  • Negligible Lumen Depreciation
  • Highest lifespan and reliability in the industry
  • Ability to withstand higher surrounding temperatures: -30°F to +130°F
  • Ability to create more variations and styles of products, such as the T5 LED tube and Dual Shine LED tube
  • And lastly, this design is quicker, easier and less expensive to produce, while being more efficient.
