Portable Mini Projector Carry
Portable mini projector that is small, Q version of the projector, and the "big projector" the opposite, so the portable mini projector can be understood as miniature small and lovely projector, micro-projector design is lovely.
Portable Mini Projector Concept
Usually this projector for the phone size, built-in battery, in the case of no electricity with 1-2 hours or more, the use of LED light source, the general weight does not exceed 0.2KG, can carry (can be put into the pocket), shell Color use is relatively traditional projector is rich, the design can not be too mechanical style, sometimes we also call it portable projector, mini projector, or pocket projector! Such as the shadow of micro-projector MOV196 series belong to this category!
To prevent strong collision, squeeze and vibration. Because the strong earthquake can cause the displacement of the liquid crystal, the impact of the three LCD when the convergence, there RGB color does not coincide with the phenomenon, and optical system lens, the mirror will produce deformation or damage, affecting the image projection effect, The lens will damage the track under the impact, resulting in lens stuck, and even lens rupture can not be used.
Pay attention to the use of environmental dust and ventilation.
Polystyrene LCD panels used in January 2013 are generally only 1.3 inches, and some even only 0.9 inches, and the resolution has reached 1024X768 or 800X600, that is only 0.02mm per pixel, dust particles enough to block it. And because the projector LCD board full heat generally have a dedicated fan to tens of liters of air per minute flow of its air cooling, high-speed air flow through the filter after the dust may also be entrained with small dust particles, they friction each other to produce static electricity Adsorbed in the cooling system, which will have an impact on the projection screen. Therefore, in the use of the projector dust is very important, must be strictly prohibited smoking, smoke particles more easily adsorbed in the optical system. Therefore, regular or regular cleaning of the dust at the entrance of the dust net.
To January 2013 polysilicon LCD panels are more afraid of high temperature, newer models in the vicinity of the LCD panel are equipped with temperature sensors, when the air inlet and dust filter is blocked, airflow is not smooth, the projector temperature will be rapid Rise, then the temperature sensor will alarm and immediately cut off the light source circuit. Therefore, to keep the air inlet open, timely cleaning filter is necessary.
Ceiling installation of the projector, to ensure that the upper space of the room ventilation cooling. When lifting the projector, often only pay attention to the surrounding environment, and forget the problem of hot air rise, work on the ceiling of the projector, the ambient temperature and the following are very different, so can not ignore this point.
Light Source Part
Most of the projectors use metal halide (Metal Halide), in the light state, the bulb voltage at both ends of 60-80V or so, the bulb gas pressure greater than 10kg / cm, the temperature is thousands of degrees, filament in a semi-molten state. Therefore, in the boot state is strictly prohibited vibration, move the projector, to prevent the bulb burst, stop using immediately after the power can not be disconnected, let the machine heat automatically after the completion of the machine, the heat dissipation in the machine caused by damage is the most common projector One of the reasons for the repair. In addition, reducing the number of switching machines is useful for lamp life.
