摘要： A color temperature adjusting system includes a processing unit, a constant-current drive unit, and an light emitting unit (LED) unit including two unmatched LED modules with different basic color temperatures. A table records a relationship between coefficient values and current values for the current(s) flowing through the two LED modules. The processing unit selects one of a number of predetermined formulas to calculate the coefficient value by comparing a desired value with a threshold value, and further determines the current values according to the calculated coefficient value listed in a table. The constant-current drive unit includes two drive module generating modulating signals to adjust the respective values of the current flowing through the two LED modules to match the determined current values, thereby adjusting the color temperature value of the LED unit to the desired level. A related method is also provided.

摘要： A Fresnel composite lens for used in an infrared touch control device including a number of infrared emitters and an infrared receiver. The Fresnel composite lens includes a number of Fresnel lens portions having a plurality of parallel optical axes, each Fresnel lens portion having a corresponding optical axis. Each Fresnel lens portion corresponds to a particular emitter and is configured for converging and directing light from a corresponding infrared emitter to the infrared receiver. The Fresnel lens portions are configured for focusing the light from the respective infrared emitters at a common point located on the infrared receiver.

摘要： An LED illuminating device includes a base, an LED substrate mounted on the base, at least one LED on the substrate and an envelope fixed on the base. The envelope includes a plurality of transmission regions and a plurality of reflective regions. The lights beams emitted by the LED reaches the envelope. A first portion of the light beams reaching transmission regions can pass therethough. A second portion of the light beams are internally reflected in multiple times by the reflective regions until they finally escape to outside through the transmission regions. The direction of the light beams can reach various locations of each of the transmission regions at various angles.

摘要： An LED lamp includes a socket and a shallow dish-shaped body detachably connected to the socket. The body includes a rear cover, a transparent front cover, a lamp board, a number of LED light sources, a driving circuit board, and a fixing member. The front cover has a honeycombed pattern including a plurality of cells. The LED light sources are mounted on the lamp board facing an inside of the front cover, and each LED light source is configured to emit a light beam toward the front cover so as to create a light spot in a corresponding cell on the front cover. The driving circuit board is electrically connected to the socket and the lamp board, and is configured for driving the LED light sources to emit light beams. The fixing member is configured for fixing the rear cover, the driving circuit board and the lamp board together.
