NOVELTY - The apparatus has a housing (1) for defining a top opening (11) at a top side of the housing. A lamp socket (2) is mounted on inside of the housing. A lamp bulb (8) is installed in the lamp socket. An aroma capsule (7) is detachably accommodated in the top opening of the housing and heated by radiating heat from the lamp bulb to give off fragrance. The aroma capsule is provided with a placeable heat-transfer container (71) accommodated in the top opening of the housing and defining a top opening (73) and aromatic substance (75) held in the placeable heat-transfer container.    USE - Aroma-diffusing apparatus for holding aromatic substance e.g. block of aromatic wax (claimed) such as solid aromatic wax. Can also be used for essential oil and perfume.    ADVANTAGE - The placeable heat-transfer container is made of aluminum film having characteristics of lightweight, thin wall thickness and better heat conductivity, so that the placeable heat-transfer container can transfer heat energy produced by the lamp bulb to the aromatic substance rapidly to cause the aromatic substance to diffuse better smell and a user needs not to worry about breaking down the placeable heat-transfer container and to prepare an extra container for holding the solid aromatic substance, thus eliminating fragile drawback of ceramic or glass containers. The apparatus allows the sealing film to seal the solid aromatic substance in the placeable heat-transfer container, thus maintaining quality of the aromatic substance. The apparatus allows the aromatic substance to be sealed in the placeable heat-transfer container and not carried in an ordinary container, so that the user simply needs to remove the sealing film from the placeable heat-transfer container without touching the aromatic substance, while using the aromatic substance and put a new aroma capsule in the top opening of the housing to replace the used aroma capsule without necessity of cleaning used aroma capsule in a convenient manner. The apparatus allows the breathing film to retain molten aromatic substance if the apparatus falls to a floor accidentally, thus preventing the molten aromatic substance from flowing to the lamp bulb and the lamp socket or to wet an internal circuit of the lamp socket, avoiding contamination and ensuring a high level of safety. The apparatus allows electrodes to be arranged in the lamp socket in a parallel manner, so that the ends of electrical wires can be conveniently and straightly connected to the electrodes in a parallel manner without bending. The apparatus allows a first electrical wire inserted from a bottom side of a sloping panel through a first cable-retaining notch toward a top side of the planar panel, extended downwardly through a second cable-retaining notch to the bottom side of the planar panel and turned forwardly out of a high tensile strength cable bracket to a power source such that electrical cables are respectively secured to four cable-retaining notches of the high tensile strength cable bracket to avoid curving in a large angle, so that the high tensile strength cable bracket transfers stretching force to the lamp socket when the electrical wires are stretched by external force, thus avoiding disconnection of the electrical wires from the electrodes of the lamp socket. The apparatus allows the high tensile strength cable bracket prepared by a thermal conductive plate unit, so that the high tensile strength cable bracket shows Z-shaped configuration for supporting the electrical wires in a smoothly curved manner when viewed from one side, thus avoiding internal conductor damage.    DETAILED DESCRIPTION - The aromatic substance is block of aromatic wax. The aroma capsule comprises a breathing film (70) made of material e.g. fabric, fiber cloth, porous plastic membrane and porous metal foil.
