A light emitting device is provided to produce white light with a stable correlated color temperature and stable color coordinates. The light emitting device includes a blue LED chip and a yellow phosphor. The blue LED chip has a peak wavelength X slightly smaller than the peak wavelength Y of the phosphor such that when the light emitting device is subjected to a predetermined operating current, the phosphor decays due to thermal effect, and the LED chip has its emission spectrum red-shifted to substantially match with the excitation spectrum of the phosphor. At this time, the excitation ability of the LED chip is increased and causes an increase of yellow power output from the phosphor that substantially compensates a decrease of yellow light output caused by the phosphor.

The present invention discloses a cooling system with a passive heat dissipation structure, the cooling system includes plural heat conducting pipes, and a shielding tube included to surround the heat conducting pipes. The heat generated from a heat source placed below the cooling system heats the surrounding fluid (air) and turns it into heated fluid. The heated fluid is lower in density and is dissipated away through convection by the heat conducting pipes, leaves its original space to cooler fluid (at room temperature). The mixing of the heated fluid with the cooler fluid can be prevented by the heat conducting pipes, and the heat convection of the heat source by the cooler fluid is increased. With the implementation of the present invention, the benefits of easy implementing, easy to use, requiring no extra energy and saving costs are achieved, and the heat of the heat source is promptly dissipated away.

A cooling apparatus using solid-liquid phase change material (solid-liquid PCM) is disclosed. The cooling apparatus includes a pipeline, a housing enclosing the pipeline, and the solid-liquid PCM filling in an interior of the pipeline and a space between the pipeline and the housing. The solid-liquid PCM can contact a heat source and absorb the heat generated by the heat source, so as to transform from solid state to liquid state. The solid-liquid PCM in the liquid state can circulate inside the pipeline and the space between the pipeline and the housing. Thus, the heat is dissipated by the means of thermal convection. Meanwhile, the heat also can be dissipated through the housing. Therefore, the heat dissipation can be achieved by thermal conduction and heat convection simultaneously.

An optical head-mounted display includes an eyeglass frame, a holographic optical element supported by the eyeglass frame to be confronted by an eye of a wearer, and a projector mounted on the eyeglass frame to project image information on the holographic optical element. The projector includes a LED light source, a beam-splitting polarizer, a spatial light modulator, a lens set and a mechanical one-dimensional scanner. The mechanical one-dimensional scanner reflects the transformed light beam from the lens set onto the holographic optical element in one dimension at a time. When the reflective sheet is rotated at a range of angle in a brief moment of time, the holographic optical element receives from the rotating reflective sheet an array of one-dimensional modulated light beams and reflects the latter to form a two-dimensional image in the eye because of persistence of vision.

The present invention discloses a MOCVD gas diffusion system with gas inlet baffles. With the adoption of multiple detachable air inlet baffles under the MO gas (Metal Organic gas) inlet and the hydride gas inlet, the gas diffusion system can easily and effectively reduce the pre-reaction of the MO gas and the hydride gas near the gas inlets, prevent metal diffusions around the inlets and make the metal layer generated on the wafers on the wafer carrier be very even, the MO gas used is also massively reduced to save great cost. The MOCVD process with the diffusion system of the present invention thus has a great potential in application to productions of high-performance LED epitaxy.

A time synchronization calibration method and system for image taking and coordinate reading and a delay time calculation method thereof are disclosed. The time synchronization calibration method is as follows. Firstly, every time point, a calibrator coordinate, an operation target coordinate and an image thereof are obtained. The image similarity index of every image and the image of previous time point thereof is calculated. When the image similarity index is lower than a preset similarity index, a reading time of the image is output followed with calculating the difference of the reading time and a time delay to obtain a taking time of the image. Finally, calculating the coordinate transformation of the calibrator coordinate and the operation target coordinate, and corresponding it to the image to output an image-coordinate correspondence relation. The time delay can be obtained correctly with only one test, and provided for the consequent synchronization calibration.
