Abstract: The present invention provides a light-emitting module, which comprises a light-emitting device, a light-guiding member, and an external light-guiding member. The light-emitting device emits light. The light-guiding member is disposed on the light-emitting path of the light-emitting module; the external light-guiding member is disposed on the light-emitting path of the light-emitting member. The light-guiding member distributes the light over the light-incidence surface of the external light-guiding member uniformly. After the external light-guiding member, the light is modified to axially symmetric light. Besides, the light-emitting device is disposed in a reflection ring, and a diffuser is disposed on the light-emitting path of the light-emitting device. When a minority of the light-emitting device fail, although the overall energy of the light source is reduced, the influence on the light emission of the light-emitting module is not significant.

Abstract: A light load current detection system including a detection process module and a control circuit is provided for detecting a current value of a light load current of a load in a light load mode; the detection process module including a power save unit and a voltage detection module. The power save unit sends a power save signal, wherein a cycle of the power save signal corresponds to a switch state. The voltage detection module detects an input voltage value to generate and output a detection signal. The control circuit includes a data table and a threshold, the data table showing a relation among the cycle, the current value and the input voltage value. The control circuit determines if the current value reaching the threshold, the switch is turned off in the light load module.

Abstract: A lighting module with high rending property includes a substrate, a plurality of first light emitting diode (LED) chips, a plurality of second LED chips and a wavelength conversion layer. The first LED chips are deposed on the substrate and electrically connected to the substrate. The second LED chips are deposed on the substrate and electrically connected to the substrate. The wavelength conversion layer seals the first LED chips and the second LED chips. The light emitted from the LED chips and the light emitted from the wavelength conversion layer caused by an excitation by the LED chips are mixing to form warm white light with high color rending property. The number ratio of the first LED chips to the second LED chips deposed on the substrate is 2:1.

Abstract: An LED includes a cooling block, an LED chip, two insulating layers, two electrically conductive layers and two gold wires. According to the invention, two open trenches are arranged by opening on the cooling block; the LED chip is fixed on a surface of the cooling block; the insulating layers are plated on inner walls of the trenches; the electrically conductive layers are plated on the insulating layers and are insulated from the cooling block; the gold wires are electrically conducted to the electrically conductive layers and the LED chip; since the insulating layers are only plated on parts, where the cooling block contacts the electrically conductive layers, the other parts of the cooling block are exposed, such that the cooling area is increased and the cooling performance is promoted; in addition, the invention is further to provide a cooling block assembly constituted by these cooling blocks.

Abstract: An improved structure of light emitting diode comprises that a copper clad laminate is made with a rectangular type slot thereon and a ring type slot on the outside boundary to enclose the rectangular type slot, while side wall of the slot form a natural guide angle with the surface of the copper clad laminate to further form an island type platform; a conductor being made between rectangular type slot and ring type slot is penetrated through the copper clad laminate and externally enclosed by the insulator thereby allowing conductor to be insulated; a light emitting diode chip is installed thereon; a fluorescent glue is optionally installed on the light emitting diode with a covering range smaller than the natural guiding angle of the rectangular type slot, wherein the copper clad laminate is installed on the printed circuit board.

Abstract: A clothes hanger comprises a base and hanging fins. The base comprises buckle means mounted on upper lateral surfaces of the base and a hook mounted on a top surface of the base. The hanging fins are movably mounted on lower lateral surfaces of the base for detachably hooking the buckle means. A plurality of through holes are formed on the hanging fins at intervals so that the clothes hanger can be put to use in both folded and unfolded forms and the required space for hanging the clothes can be further saved by the folded hanging fins.

Abstract: For use in a self-emitting color display device such as a cathode ray tube (CRT) having a display screen with a phosphor coating on its inner surface, a surface coating disposed on the display screen's outer surface affords improved color purity, or contrast, by reducing overlap in the color spectrum between two adjacent primary colors, i.e., between red and green and/or between green and blue. An organic dye is added to either an inner antistatic layer or an outer antireflective layer of an antireflective/antistatic outer coating on the display screen, where both of the aforementioned layers contain silane. The dye functions as a color filter absorbing only light within the frequency range between adjacent primary colors, such as between the red and green color phosphors, i.e., in the range of 460-500 nm, and/or between the green and blue color phosphors, i.e., in the range of 560-600 nm. A silane coupling agent is also added to serve as a binding agent bridging the organic dye and silane together.
