The authors use goniophotometer to experimentally measure the light flux distribution of a wall-mounted luminaire with a luminous light bulb, a direct-replacement light-emitting diode (LED) lamp, and a three-dimensional LED module with a heat pipe-based cooling system. The change dynamics of integral characteristics of the light flux is determined. The stabilized light flux for different types of light sources at different power supply voltages is measured. The obtained experimental data are used to calculate the luminous efficacy of the luminaire with the direct-replacement lamps and to determine its dependence on the supply voltage. The thermal conditions for using LEDs in direct-replacement lamps and in lamps with an original cooling system based on heat pipes are also determined.
