  • Patent number: 9657929
    Abstract: The invention relates to a lamp, comprising a light source for generating a light beam in the direction of a main axis and a first direction-dependent tilt switch for controlling the light source depending on the angle between the main axis and the vertical, wherein the switching direction of the first tilt switch extends in a main plane which runs along the main axis. This enables the use of a tilt switch which functions in only one direction and has a much simpler construction than a switch which functions in two dimensions, such as in the prior art. Furthermore, such a switch has the advantage of a small volume, which advantage is also realized when more switches are used in the lamp. According to another preferred embodiment, the lamp comprises a housing and the housing is provided with marking means for marking the position of the lamp in which the main plane extends vertically.

  • Patent number: 8764218
    Abstract: The present invention provides an illumination alert apparatus structure having a cap for use in switch control. The illumination alert apparatus which is illumination-oriented comprises a body, a power unit, and a lightbulb having an illumination unit coupled thereto. The power unit is coupled to an end of the body. The lightbulb is screwed to an external thread formed on an outward side of the body and coupled to the power unit, so as to assemble the illumination alert apparatus. The illumination alert apparatus structure dispenses with other switch-related components which might otherwise compromise the overall esthetical appearance of the illumination alert apparatus, such that the illumination alert apparatus manifests simplicity, beauty, and novelty.

  • Patent number: 8753152
    Abstract: A radially uniform spring-biased intra-pole plug connector and transformer outside the trunk configuration for an electric artificial tree is described. The radially uniform plug comprises a springed-tip and a prong, and allows the tree trunk segments to be connected at any point along their 360 degree circumference. The plug connector resembles the structure of a car cigarette lighter. A mold is used to sandwich the plug within the trunk. A plug portion of the plug connector is housed in one trunk segment, and a receptacle portion is housed in a different trunk segment, such that when the trunk segments are assembled, the plug is connected, illuminating the tree. The plug allows the electrical wiring to be hidden and housed within the trunk, providing safety, convenience to the user and giving the tree a cleaner appearance. The transformer outside the trunk configuration makes the trunk safer, more lightweight and less bulky.

  • Patent number: 8690378
    Abstract: Embodiments provide a flashlight with a bezel configured to be moved relative to a body of the flashlight to adjust the focus of the light. A locking assembly may be disposed within the bezel and configured to switch between an unlocked position and a locked position if the bezel is rotated with respect to the body. The locking assembly may include a ring-shaped outer component having first and second curved walls separated by a gap. The locking assembly may further include an inner component coupled with the light assembly, the inner component including a nub configured to be disposed in the gap if the locking assembly is in the unlocked position, and to radially push an outer surface of the outer component against the inner surface of the bezel if the locking assembly is in the locked position.

  • Patent number: 8690377
    Abstract: A portable light or other device having a safety lock may comprise: a light body for receiving a source of electrical power; a light head including a light source for producing light and engaging the light body; and a lock mechanism engaging the light body or the light head and including a threaded member and a lock member. Rotating the threaded member moves the lock member radially relative to the light body and light head for engaging the lock for preventing removal of the light head from the light body unless the lock mechanism is released by a tool. A lock support may be disposed for supporting the lock member when the lock mechanism is engaged. The lock mechanism may be retained on the light body or the light head when the lock mechanism is engaged and when the lock mechanism is released.
