Abstract:
Apparatus and associated methods relate to a diversion driver module that dynamically adds a diversion current to an LED current so that the summed current maintains a predetermined minimum holding current requirement of a phase-controlled dimmer supply. In an illustrative example, the diversion current may be a function of input AC line voltage and/or firing angle of the phase-controlled dimmer supply. The phase controlled device may include, for example, a triac. The triac may supply adjustable pulse-width current to dim the LED according to a phase control signal. The diversion driver module may include one or more heat dissipating components disposed in thermal communication with the lamp base. Some driver modules may be sufficiently compact and energy efficient to provide smooth dim-to-black performance while operating within acceptable temperature limits for reliable operation while contained in the base of a standard form factor lamp, such as an E12 full-glass lamp.

The LED light source module, the heat-dissipating cup, and the driving power source are arranged from top to bottom inside the glass shell. A top portion of the glass shell is connected to the optical portion and a bottom portion of the glass shell is connected to the lamp base. The heat-dissipating cup faces upwardly and an outer sidewall of the heat-dissipating cup forms a close contact with an inner sidewall of the glass shell. The LED light source module is fixed within the heat-dissipating cup. The driving power source is positioned under the heat-dissipating cup and a space is formed between the driving power source and the heat-dissipating cup.
Abstract:
An assembly includes a contact interface device, a lamp base and a circuit board. This device is connected to the circuit board and is used to bias the circuit board within the center of a cavity of a light bulb. This device contains two or more biasing portions that are connected to one another through a bridge portion. The biasing portions engage an interior threaded portion of the lamp base in order to lock into place and not allow the circuit board to move. The bridge portion allows the biasing portions to counteract one another and suspend the circuit board in the middle of the cavity of the light bulb.
