Description
Technical Field
The utility model relates to a LED projecting apparatus technical field, in particular to heat pipe heat abstractor of LED projecting apparatus ray apparatus.
Background
Most projectors on the market at present use LED light sources, also known as LED projection. Also partly used are conventional light bulb sources, so-called bulb machines. The bulb machine has the advantages of high brightness and more excellent projection picture, however, the traditional bulb projector adopts a high-pressure mercury lamp bulb, the service life is only 2000-4000 hours due to serious heat generation, and the bulb is not completely extinguished but needs to be replaced when the light decay influences the image quality, so the actual service life is less than 2000 hours. Therefore, the bulbs are replaced frequently and even the bulbs are expensive and gradually eliminated by the market. Since the appearance of projectors with LED light sources, the projectors rapidly occupy the market of the projectors by virtue of the advantages of good color, long service life, easy recovery, small size, convenient carrying and the like, but the LED projectors in the market of the projectors are generally low in lumen, insufficient in light intensity and high in noise, and are subject to the following problems of mass. The fundamental reason why these problems occur is that the Junction Temperature (actual operating Temperature of the semiconductor) of a COB light source (high power integrated surface LED light source) is too high, and the conventional copper tube heat transfer heat dissipation device on the market cannot effectively reduce the Junction Temperature, so that the COB power is reduced to operate in an unsaturated state in the industry, and the operating life of the COB power is prolonged. Or the working temperature of the COB light source is reduced by controlling the temperature in the optical machine cavity of the projector through external semiconductor refrigeration.
The drawbacks of both schemes are also obvious, and first, in the case of a short pulse width and a low Duty Cycle (Duty Cycle), the peak junction temperature may be much higher than the average junction temperature, which becomes a main limiting factor of the device operation characteristics. In this case, the junction temperature is not only related to the power loss of the device, but also depends on the shape of the current pulse, the pulse width and the repetition frequency to a large extent, so that the concept of thermal resistance is not applicable. The power reduction due to the duty cycle does not necessarily reduce the temperature effectively. Second, because it is that external semiconductor refrigeration changes intracavity temperature environment, rather than starting from COB at all, consequently under specific temperature environment, the intracavity can produce condensation phenomenon, leads to humidity to increase in the cavity, if too moist, humidity can directly get into electronic components through electronic surface gap, causes electronic product internal equipment malfunctioning, bad phenomena such as short circuit.
In view of LED projecting apparatus during the work uses, for the up-down reversal dual mode uses, so the utility model discloses a heat radiation structure that radiating theory of operation implemented circulates from top to bottom fully shifts to outside and effectively dispels the heat from the heat in the COB root point photoelectric conversion to reduce the heat consumption on COB play plain noodles, make its thermal impedance and steady state thermal impedance be close to mutually in the twinkling of an eye, make light source purity higher.
