The introduction of electronic ballast in lighting systems design has dramatically revolutionized the lighting space. This is orchestrated by the entrance of the Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs) into the lighting market. The CFLs currently being used in domestic and industrial lighting systems provide highly competitive alternatives to conventional incandescent lamps. The electronic ballast incorporated into the CFLs helps eliminate the flickering and slow starting flaws prevalent in traditional fluorescent lamps. To properly evaluate the performance characteristics and limitations of the CFLs, a critical analysis of its electronic circuit becomes imperative. To this end, this paper presents experimental and simulation analyses of the CFL circuits. To achieve this, two Futina CFL bulbs of 11W and 15W model YPZ220/11-BMSP RR/RDD and YPZ220/15-BMSP RR/RDD, respectively, were analyzed and experimentally verified. A function-based programming paradigm was applied to develop a graphical user interface (GUI) used for the circuits analyses. The GUI is designed using MATLAB graphical user interface development environment (GUIDE). Experiments were conducted to obtain the performance characteristics of the CFLs, and measurements show that the 11W lamp has a higher amplitude than the 15W lamp. However, both lamps show similar waveforms after 300 seconds. The maximum voltage amplitudes for both CFLs are the same, with a peak value of 218V. The current waveforms in the spectral domain gave a maximum amplitude of 0.3 A for the 11W CFL and 0.2 A for the 15W. The voltage frequency (0.00196) of both CFLs are the same, whereas the current frequencies are different. This indicates that the wattage of a CFL does not affect the frequency of its voltage waveform. The frequency of the 11W CFL current (0.00157) is higher than that of the 15W CFL current (0.00784). This implies that the higher the CFL wattage, the lower the frequency of its current waveform. Additionally, simulation results revealed that the key difference between the CFLs is the current total harmonic distortion (THDI), which increases with an increasing rated power of the CFL or the aggregation of a number of the smaller rated CFLs.

“…If the filaments get too cool by dimming the lamp, it may undergo severe rapid degradation of the thermionic material on the filaments. To provide dimmable features while keeping the useful life of CFL high, new CFLs ballast designs with dimming function was developed [7][8][9][10]. A low-cost ballast, charge-pump based circuit and voltage dimming control without using any integrated circuit have been designed in [7].…”

The widespread use of compact fluorescent lighting in residential and commercial application is a significant source of power pollution. The ballast that controls the operation of this type of lamp is known to generate peak currents and introduce harmonics into the distribution systems. Currently, compact fluorescent lamps (CFLs) with dimming function have been introduced for brightness control using conventional dimmers. Typically, dimmers utilize a phase-control circuit with triac to vary the conducting period of each half cycle of lamp currents, thus reducing the light output. This paper focuses on analyzing the harmonics generated from dimmable CFLs. Therefore, laboratory tests on various CFLs are conducted to tap the load current behavior under different conditions. Frequency domain analysis is then performed to investigate the generated harmonics from CFLs. For comparison purposes, the performance of dimmable CFLs and incandescent lamps at various brightness is also investigated. Furthermore, harmonic levels of dimmable and non dimmable CFLs is experimentally evaluated and compared. The results show that the dimmable CFLs produce more harmonics compared to incandescent lamps and non dimmable CFLs.

Compact Fluorescent Lamp (CFL) and LightEmitting Diode (LED) are energy efficient light sources. However, they have a disadvantage that they cannot be directly dimmed with a triac dimmer. This article briefly explains the incompatibility issues, and suggests a CFL ballast circuit to overcome this disadvantage. The ballast is based on resonant mode topology, with additional circuitry for triac interface and dimming control. Furthermore, this article also presents, with few modifications to the CFL ballast circuit, an LED driver circuit that is dimmable with triac dimmer. Experimental results show that both proposed circuits are able to be dimmed down close to 10% of the light output.
