An LED lamp includes a LED assembly comprising at least one LED operable to emit light when energized through an electrical path. A heat sink structure is thermally coupled to the LED assembly for dissipating heat to the ambient environment. An aromatic structure is thermally coupled to the heat sink structure such that the aromatic structure is heated by the heat dissipated from the heat sink.

A capsule is configured for use with a base unit having a fan and an air opening for an airflow of air driven by the fan. The capsule includes a housing with a port. The housing engages and disengages the base unit. The capsule also includes a volatile substance member and a seal member that is supported by the housing for movement between a sealed position and an unsealed position. The seal member seals the port when the capsule is disengaged from the base unit. The projection is received in the capsule when engaged with the base unit to support the seal member in the unsealed position such that air moved by the fan flows through the port.

Provided is an insect pest control product that is applicable to a water-based insecticidal composition and can continue to exert stable performance over a long period of time. The insect pest control product comprises a thermal vaporization/diffusion absorbent wick for vaporizing and diffusing a water-based insecticidal composition containing a pyrethroid insecticidal component having a vapor pressure of 210.sup.4 to 110.sup.2 mmHg at 30 C., a glycol ether compound and/or glycol compound having a boiling point of 150-300 C., and water. The thermal vaporization/diffusion absorbent wick has an insecticidal component/compound condensation ratio (P.sub.1/P.sub.2) within the range of 1.2-6.0, where the insecticidal component/compound condensation ratio (P.sub.1/P.sub.2) is calculated from a weight ratio (P.sub.1) of the pyrethroid insecticidal component and the glycol ether compound and/or glycol compound contained in the thermal vaporization/diffusion absorbent wick after use, and a weight ratio (P.sub.2) of the pyrethroid insecticidal component and the glycol ether compound and/or glycol compound contained in the water-based insecticidal composition before use.

The present invention relates to fragrances compositions. The present invention, more specifically, relates to the use of a blend of 1,3-butanediol and a glycerol ketal derivative for fragrance compositions. The present invention also discloses fragrance compositions using such a blend to provide controlled evaporation profile.

Chemical carriers for fragrances include components in proportions that enable a rate of diffusion or volatilization of at least one fragrance to be tailored. Such a fragrance carrier may include isopropyl myristate (IPM), 3-methyoxy-3-methyl-1-butanol (MMB), and cyclomethicone. The fragrance carrier may enable a fragrance to be delivered by a variety of different dispensers. Methods for optimizing the rates of diffusion or volatilization and other characteristics of fragrances using such a fragrance carrier are also disclosed.

A refill for holding at least two compositions comprises a container including a body and first and second compositions disposed within the body such that the first and second compositions are substantially separated and the second composition is disposed above the first composition. The refill further includes a tube disposed within the body of the container such that the tube contains the first and second compositions, wherein the tube has an inner diameter and an outer diameter. Still further, the refill includes a wick disposed within the tube, wherein the wick contains the first and second compositions and has a diameter that is smaller than the inner diameter of the tube to create a gap between the wick and the tube is smaller than the inner diameter of the tube to create a gap between the wick and the tube.
