The present invention relates to a bag with built-in lighting system for illuminating items kept inside the bag. The bag is comprised of motion sensors that detect if the user opens the bag, and accordingly activates the lighting unit placed inside the interior of the bag. Also, the light is automatically turned OFF when the bag is closed. The bag integrated with lighting system allows users to clearly view any item placed inside the bag and eliminates the difficulty of trying to find items in bag under low-light or no-light conditions. Additionally, the lighting system can be integrated into any type of bag including purses, handbags, briefcases, or the like.

A lighting device, such as a replacement lighting device, comprising a light source (LS), e.g. LEDs, for producing light along an optical axis (OA). A heat sink (HS) made of a material with an electrical resistivity being less than 0.01 Ωm, e.g. a metallic heat sink being a part of the housing, transports heat away from the light source (LS). A Radio Frequency (RF) communication circuit (CC) connected to an antenna (A) serves to enable RF signal communication, e.g. to control the device via a remote control. Metallic components, including the heat sink (HS), having an extension larger than 1/10 of a wavelength of the RF signal are arranged below a virtual plane (VP) drawn orthogonal to the optical axis (OA) and going through the antenna (A). Hereby a compact device can be obtained, and still a satisfying RF radiation pattern can be obtained. The antenna can be a wire antenna or a PCB antenna, e.g. a PIFA or a IFA type antenna. In a special embodiment the antenna is formed on a ring-shaped PCB with a central hole allowing passage of light from the light source. Preferably, the antenna is positioned at least 2 mm in front of the heat sink (HS).

The devices may include a housing including a first wall, a second wall, and one or more side walls between the first wall and the second wall, at least one solar panel to generate solar energy, and a rechargeable battery to store the solar energy generated. The devices may include a plurality of operating modes for controlling lights within the housing, and a microprocessor for controlling the operating modes.

Methods and apparatus for providing circadian-friendly LED light sources are disclosed. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum) wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio the relative circadian stimulation is varied while maintaining a color rendering index above 80.
