Publication number: 20140043116Abstract: A switch linkage mechanism includes a self-holding solenoid, at least a linkage shaft, at least a twist bar and at least a copper strip set. When the twist bar is at a circuit-closed position, the copper strip set is electrically connected to the high-current circuit breaker. When a self-holding solenoid is activated to pull up a central axle of the self-holding solenoid, the central axle pulls a joint of the linkage shaft and the central axle, and then it pushes the twist bar to be rotated to an circuit-opened position, so that the twist bar stretches out the copper strip set to cause the switch linkage mechanism to be electrically disconnected from the large-current circuit breaker.Type: ApplicationFiled: December 11, 2012Publication date: February 13, 2014Applicant: TATUNG COMPANYInventors: Wen-Tang PAN, Wade-Lee WANG

Patent number: 8303165Abstract: The present invention provides a stirring mechanism with magnetic force. It has a central rotary arm with permanent magnet, as well as a plurality of lever arms, each having one respective permanent magnet. A track disk rotates synchronously with the central rotary arm. An elliptic track slot in the track disk traps the lever arms to swing forward and backward. The lever arms exhibit alternate motions of approaching and leaving, thereby causing a stirring effect.Type: GrantFiled: December 9, 2010Date of Patent: November 6, 2012Inventor: Wade Lee Wang

Patent number: 8071159Abstract: The present invention provides a method of making pure white light source. A phosphor powder which at least comprises three elements Zn, Se, and O is used for being excited by a purple-LED to emit pure red light (650 nm). The phosphor powder is coated on the purple-LED (Ex. chromaticity coordinate of x:0.26, y:0.10), and then placed aside a pure green-LED (or chip), when the purple-LED and the green-LED are electrified, a pure white light source with high color rendering index and high color saturation is obtained.Type: GrantFiled: March 23, 2009Date of Patent: December 6, 2011Inventor: Wade Lee Wang

Patent number: 7938570Abstract: A quick-release mounting mechanism for a worklight enabling the worklight to be quickly and easily mounted on and demounted from a tripod support stand and enabling an individual worklight head to be quickly and easily mounted on and demounted from a base stand or other support member such as the handle of a spring clamp or other clamp member. The mounting mechanism includes a latch member on the worklight base or on an individual worklight head that cooperates with an actuator mounted in the support stand or other support member. The latch member is received in a hole in the support and the actuator is formed to engage a catch on the latch member when the worklight or individual worklight head is in position on the support.Type: GrantFiled: June 21, 2004Date of Patent: May 10, 2011Assignee: EML Technologies LLCInventors: Wade Lee, Donald R.

Patent number: 7741786Abstract: An outdoor lighting control method and apparatus for use with an outdoor lighting fixture that automatically detects the changing length of the day and provides for automatically turning off the light after a shorter period of illumination during shorter summer nights and after a longer period of illumination during longer winter nights. The control method measures the elapsed time interval over which night sets in, for example, by sensing light levels characteristic of the onset of dusk and the onset of night and measuring the elapsed time between the two sensed light levels, and then automatically turns on the lighting fixture for nighttime operation for a duration that depends on the measured elapsed night-onset time.Type: GrantFiled: January 2, 2007Date of Patent: June 22, 2010Assignee: Illumination Dynamics LLCInventor: Wade Lee

Publication number: 20090295270Abstract: The present invention relates to a device with electron beam excitation for making a white light source. The device with electron beam excitation comprises: an electron emissive layer for providing an electron beam; and a fluorescent layer comprising a fluorescent powder, wherein the fluorescent powder comprises at least four elements of Zn, S, Se and O. The fluorescent layer can be excited by an electron beam and then emit white light. Accordingly, the present invention can provide a white light source with high color rendering index.Type: ApplicationFiled: October 8, 2008Publication date: December 3, 2009Applicant: Tatung CompanyInventors: Wade-Lee Wang, Wen-Hsien Cheng, Tzung-Han Yang

Patent number: 7579567Abstract: An ergonomically designed switch for a halogen worklight. The worklight includes a switch housing attached to the worklight head and a push-action switch mounted in the switch housing for energizing one or more halogen lamps mounted in the worklight head. An ergonomic switch is operated by pressing on a switch button, which is formed to present an ergonomically sized engagement surface to the user. The size of the engagement surface is related to the typical size of a finger pad of the human hand. Through the simple expedient of providing a substantial switch button on the actuating shaft of the switch and sizing the engagement surface of the button to correlate with the size of the human hand, the ease and comfort of operation of the worklight is dramatically improved over worklights having awkward switch mechanisms long thought in the prior art to be unavoidable.Type: GrantFiled: April 1, 2006Date of Patent: August 25, 2009Assignee: EML Technologies LLCInventors: Wade Lee, Donald R. Sandell

Patent number: 7488941Abstract: A motion-activated decorative lighting fixture with a PIR motion detector hidden behind a decorative slotted wall of the fixture body. The motion-activated decorative lighting fixture includes a motion detector housing that forms an integral part of the lighting fixture body. The housing includes a slotted vertically extending exterior wall around the housing with an array of elongate vertically extending slots horizontally spaced apart from one another and extending along at least a portion of the wall. One or more PIR sensors are disposed within the housing, and a segmented Fresnel lens array is disposed within the housing behind the slots to direct infra-red energy from a monitored field of view to a sensor. The lens array includes a plurality of columns of lenslets, at least a portion of which have at least two lenslets disposed one above the other. Each column is aligned with a corresponding slot so as to direct infra-red energy from a monitored zone passing through the corresponding slot to a sensor.Type: GrantFiled: July 3, 2006Date of Patent: February 10, 2009Assignee: EML Technologies LLCInventors: Wade Lee, Donald R.

Patent number: 7375313Abstract: A motion-activated light fixture having an aimable motion detector with a zonal configuration providing improved monitoring of the region behind the motion detector. In one embodiment the motion detector defines a first plurality of generally forward-looking detection zones for monitoring the region in front of and to the sides of the motion detector, the forward-looking detection zones having a side-to-side coverage angle of at most 180 degrees and having forward zones for monitoring the far region in front of the motion detector. A second plurality of detection zones for monitoring the region behind the motion detector forms a zonal pattern angulated with respect to the zones of the first plurality monitoring the far region. At least some of the detection zones of the second plurality extend generally in the backward direction although in some embodiments the motion detector head must be tilted down through a pre-established offset angle before the angulated zonal pattern begins to look backward.Type: GrantFiled: November 29, 2003Date of Patent: May 20, 2008Assignee: EML Technologies LLCInventors: Wade Lee, Donald R.

Publication number: 20070252067Abstract: A locking latch used with a telescoping support stand having one or more telescoping sections. Each section includes an inner tubular member with a plurality of positioning holes along its length and an outer tubular member with a latch hole positioned typically near the upper end of the outer member so as to line up in registration with the positioning holes as the inner tubular member is extended out of the outer tubular member. The outer member carries a latch mechanism comprising a latching arm that that has a locking disposition in which the arm extends through the outer member latch hole and one of the inner member positioning holes in registration with the outer member latch hole to hold the inner and outer tubular members in substantially fixed extension with respect to one another.Type: ApplicationFiled: April 25, 2007Publication date: November 1, 2007Inventor: Wade Lee
