  • Publication number: 20110305042
    Abstract: A microcrystalline wax fragrance emitting light comprises (1) a light body with a light source creating heat and (2) a microcrystalline wax which acts as an emission media, emits fragrance, is mounted on said light body, detachable, and replaceable from said light body. The microcrystalline wax acts as a fragrance emission media which emits fragrance and is supplemented on the decorative lighting, enables the lighting to illuminate, decorate, and release fragrance continuously. The microcrystalline wax used in the present invention mainly utilizes the heat of the light source to facilitate the release of fragrance, whereby provides stronger fragrance emission. In addition, the microcrystalline wax which acts as an emission media is detachable and replaceable from the decorative lighting, allows a user to replace it freely with an emission media according to the user's favored shape and fragrance.

  • Publication number: 20110168803
    Abstract: The invention relates to perfume diffusing devices, particularly, to a microcrystalline wax housing perfume diffusing device, comprising a light-transmitting microcrystalline wax housing and electronic component. The housing has a first cavity zone inside which perfumed volatile material, being perfume-volatilizable, is placed. The electronic component is inside the housing; and includes a LED light, battery compartment, and power switch. The perfumed volatile material in the first cavity zone can volatilize perfume, and the light from the LED of the electronic component can penetrate the housing and shine out, so the device functions as ornamentation and illumination, which richens the function of the device and widens its applications. The housing is formed of microcrystalline wax and can emit perfume itself, hence the invention has a relatively long performance life because when the perfumed volatile material is used up or unable to emit perfume, the microcrystalline wax can still emit perfume itself.
