  • Light emitting device with a LED strip
    Patent number: 10775005
    Abstract: A light emitting device (1) comprising a longitudinal direction, a longitudinal axis (L) extending in the longitudinal direction, a transversal direction, a transversal axis (T) extending in the transversal direction, a height direction being perpendicular to both the longitudinal direction and the transversal direction and a height axis (H) extending in the height direction, a sleeve (2) extending in parallel with the longitudinal axis and comprising a first part (21) made of a transparent or translucent material, a second part (22) made of a diffuse material, and a channel (23) extending in parallel with the longitudinal axis and being provided in the first part of the sleeve, a reflector (3) comprising a cavity (31) extending in parallel with the longitudinal axis, a substrate (4), and a plurality of LEDs (5) adapted for, in operation, emitting light, and being arranged on the substrate (4) in such a way as to extend in a direction parallel with the longitudinal axis of the light emitting device, the subst

  • Utility lighter
    Publication number: 20030022122
    Abstract: The present invention is directed to a utility lighter having a housing, a nozzle, a lighter fluid reservoir, a conduit, an igniter assembly, a valve actuator, and a locking device. The housing has a top side, a bottom side, sides, a distal end, and a proximal end. The nozzle extends away from the distal end and has a nozzle tip. The lighter fluid reservoir is in the distal end. The conduit delivers the lighter fluid from the reservoir through the conduit to the nozzle tip. The igniter assembly generates a spark at a spark gap near the nozzle tip to ignite the lighter fluid, and has a piezoelectric component. The valve actuator is associated with the lighter fluid for selectively releasing the lighter fluid from the reservoir, and the igniter assembly.
