A lighting apparatus is provided with a housing forming a battery housing and a light housing separated via a partitioning wall. A light module is supported by the light housing and includes a heat sink located at least partially within the light housing and at least one LED supported by the heat sink. A battery receptacle formed within the battery housing to slidingly receive a battery pack at least partially into the battery housing. An intake opening is formed within the partitioning wall and an air vent is formed in fluid communication with the light housing. In operation, an airflow passes in thermal contact with the battery pack from the battery housing into the light housing through the intake opening, and from the light housing in thermal contact with the heat sink out of the air vent.

A lighting apparatus includes a light source module, an internal housing, an exterior housing and a sliding track. The light source module including a LED module. The LED module may include multiple types of LED chips of different parameters that may be controlled to mix a desired parameter. The internal housing has a light opening and a protruding block. The light source module is fixed to the internal housing and a light of the LED module passes through the light opening. An exterior housing having a sliding groove. The exterior housing encloses the internal housing and allows the protruding block of the internal housing moving along the sliding groove to change a tilt angle of the light with respect to the exterior housing. The sliding track is used for the exterior housing to move along the sliding track for further adjusting an output direction of the light.

This disclosure relates to a surgical lighting device for generating a spot of light on a surgical site for use in combination with a fluorescence imaging device. The lighting device comprises a support structure, a subsurface which may be coupled to the support structure to seal the lower surface of the device while allowing light to pass through and a plurality of light sources emitting white light and placed between the support structure and the subsurface. The device further includes a plurality of NIR (near infrared) filters, each NIR filter being associated with a light source and being configured to substantially prevent the transmission of wavelengths within a wavelength band from 680 nm to 900 nm, while minimizing the change in the color temperature of the light spot.

A LED light with built-in Air flow device has AC-to-DC circuit to get DC current to supply power to LED or LEDs and-to charge inside rechargeable batteries and to the inside air flow related device or other product(s). The LED light connect IC and control circuit to make setting, changing, adjust of the said at least one of (A) LED(s) colors, brightness, on-off, duration, cycles, frequency, sequential, flashing, color changing, color selection, auto changing, or other LED light effects, (B) Air flow related parts to get desired speed of rotating fan or blade, on-off, duration, timer, countdown timer, or other desired air flow related function(s); by at least one of (1) trigger system, (2) switch, (3) sensor, (4) motion or moving or radar sensor, (5) IR or RF remote control system, (6) power fail sensor, (7) built-in Auto-Off-On or multiple selection positions switch, (8) other related LED or air flow or air-freshener or fragrance or essential oil diffusor parts or accessories; wherein the LED light connect with (i) AC power source by prongs with or without folding features, (ii) DC power from at least one outside transformer, power bank, DC power from cigarette-plug, USB related DC power source, DC power storage device, solar module, or DC generator.

A light fixture may include a casing and a support assembly configured to support and move the casing. The light fixture may include a light source assembly housed inside the casing and configured to generate visible light radiation of different colours. The light fixture may further include a control device configured to control the light source assembly based on the position or the movement of the casing or based on a parameter correlated to the position or the movement of the casing.
