20110140640 | FOLDABLE TABLE LAMP - A lamp includes a head, a support arm and a base. The head includes a light emitting member. The support arm is rotatably connecting to the head. The support arm includes a first pushing member and a second pushing member. The base includes a moveable contact and a stationary contact. The moveable includes a spring tab. When the support arm is rotated to a first position, the first pushing member abuts against the spring tab to be deformed, and the spring tab connects to the stationary contact. The light emitting member is in a power on state. When the support arm is rotated to a second position, the second pushing member abuts against the spring tab to be deformed, and the spring tab disengages from the stationary contact. The light emitting member is in a power off state. | 06-16-2011 |
20110176303 | DOUBLE-SIDED LED LAMP - A double-sided LED lamp includes a shell, a plastic circuit board (PCB) and an optical film. The shell is made of translucent or transparent material. The PCB includes a number of rows of LEDs for emitting light beams, and defines a number of rows of through holes. The optical film facing the LEDs can reflect some of the light beams through the number of holes and also allow some of the light beams to pass through. | 07-21-2011 |
20110181166 | LED ILLUMINATING DEVICE - An LED illuminating device includes a heat sink, a first substrate, a second substrate and a connector. The heat sink comprises a first end, a second end opposite to the first end along the axial direction of the heat sink. The first substrate mounted on the first end, the second substrate mounted on the second end, the second substrate has a size smaller than the first substrate. Heat generated by the first substrate is transferred to air and will not accumulate and be transferred to the second substrate. Additionally, because the first substrate and the second substrate are spaced by the heat sink, the heat radiation efficiency is improved. | 07-28-2011 |
20110194286 | ADJUSTABLE LAMP DEVICE AND HOLDING MECHANISM THEREOF - A lamp device includes a lamp seat defining a first through hole, a lamp main body defining a second through hole, and a holding mechanism.
