Patent number: 9420651Abstract: A light-emitting diode (LED) module and a method for operating the same are disclosed. The LED module is supplied through an external voltage source. The LED module includes a bridge rectifying unit, a LED unit, and an integrated circuit (IC) unit. The bridge rectifying unit rectifies the external voltage source into an inner DC voltage source. The LED unit is electrically connected to the bridge rectifying unit and driven through the DC voltage source. The IC unit is electrically connected to the bridge rectifying unit and the LED unit and is supplied through the DC voltage source, thus providing a piecewise constant-current control or a piecewise variant-current control to the LED unit.Type: GrantFiled: October 25, 2011Date of Patent: August 16, 2016Assignee: INTERLIGHT OPTOTECH CORPORATIONInventors: Yu-Chou Hu, Hsi-Yan Chou

Publication number: 20140252947Abstract: An illuminant device with over-temperature protection is electrically connected to a power source and includes a housing, a illuminant element, a resistor, and an over-temperature protective element. The housing includes an upper portion, a lower portion opposite to the upper portion, and two accommodating spaces communicating with the upper end and the lower end respectively. The illuminant element is placed on the upper portion. The resistor is located within one of the accommodating space and electrically connected to the illuminant element. The over-temperature protective element is located within the other accommodating space and electrically connected to the illuminant element. The over-temperature protective element senses temperatures of the illuminant element and selectively breaks the power source, such that the illuminant element is switched between conductive and non-conductive.Type: ApplicationFiled: March 5, 2013Publication date: September 11, 2014Applicant: INTERLIGHT OPTOTECH CORPORATIONInventors: Hsi-Yan CHOU, Yu-Chou HU, Fu-Chen LIU

Patent number: 8450748Abstract: A light emitting device comprises: an LED chip array comprising a plurality of LEDs formed on a single die (monolithic chip array) and at least one discrete LED that is separate from the LED chip array connected in series with the LED chip array. In an AC-drivable device the LED chip array is AC-drivable and two or more discrete LEDs are configured to be AC-drivable. The device can further comprise a package in which the LED chip array and discrete LED(s) are mounted. The discrete LEDs are configured such that positive and negative half wave periods of an AC drive voltage are mapped onto oppositely connected LED such that oppositely connected LED chips are alternately operable on a respective half wave period.Type: GrantFiled: July 8, 2010Date of Patent: May 28, 2013Assignee: InterLight Optotech CorporationInventors: Hwa Su, Hsi-Yan Chou, Yu-Min Li, Yu-Chou Hu, Chih Wei Huang, Tzu-Chi Cheng
