Original Portable Mini Pocket DLP Projector With Waterproof Speaker

By light path can be divided into: transmission and reflection of two Reflective projector, it will light the light emitted directly onto the projection of the object, the reflected light from the object and then reflected by the mirror, and through the projection lens on the screen imaging. As the reflective projector works, the light reaching the screen undergoes secondary reflection and the light energy is greatly lost, so that the brightness of the image is low. Transmissive projector, which first light emitted by the convergence of light, transmitted through the projected pictures, appliances, and then by the lens imaging and projection on the screen to form an image. Projector optical principleDLP projector1.jpg Placed between the condenser and the light source, the concave surface of the light source, with thermal insulation, while it plays to expand the tolerance angle, improve the utilization of light. Mirror - Plane mirror, adjustable angle to change the optical axis of the optical path direction. Light source - Usually choose a large brightness, good light color bulb. Condenser - Threaded lens, usually made of plastic or plexiglass. Projector circuit main input circuit, output circuit, power transformer and cooling fan. 1, external operating device awareness.DLP projector23.jpg (1) Mirror: can be rotated in the vertical direction, and can do 360-degree rotation in the horizontal plane. Adjust the mirror, you can change the main optical axis of the projector light path direction, thereby adjusting the image on the screen position. When not in use, the mirror is closed, cover the projection lens, play a projection lens, mirror protection and prevent pollution. (2) projection lens: the convex lens, is the key to the formation of projection teaching material optical components. (3) Focus knob: Adjust this knob to move the projection lens up and down and adjust the distance between the projection lens and projection teaching material to make the image on the screen clear. (4) writing desk: for users to place projection materials. (5) Top closure latch: it acts as a fixed top cover. If you flip this button, you can open the top cover, while automatically cut off the power.DLP projector22.jpg (6) ribbon adjustment device: projected on the screen spot, sometimes around the edge of various ribbons, it is due to the distance between the threaded lens and the light source dispersion phenomenon, then dial the ribbon adjustment device can eliminate . (7) Lamp switching device: The projector has two light bulbs. When one light bulb is working normally, the other light bulb is used as a backup. Such as the work of the lamp is damaged, cut off the power, pull this switching device handle, the spare bulb can be replaced, so that the projector to continue to work. (8) Strong and weak light selection switch: Under normal circumstances, this switch is placed in the low light position, in order to save electric energy and extend lamp life. When the room is bright, this switch can be placed in the low light position after a period of weak light work. When the voltage exceeds 220 V, do not use the highlight switch to prevent burnout of the lamp. (9) Power switch: control the projector input power. 2, debugging: (1) Debug the projector's position. (2) Adjust the distance between the projector and the screen. (3) debugging projection lens. 3 (1) According to the projector voltage requirements, turn on the power. (2) Open the mirror cover. (3) Select the light brightness in low light position. (4) the projection film on the writing stage, small pieces should be additional blackout box. (5) Turn on the power switch, light bulb, fan work. (6) Turn the focus knob to clear the image. (7) If the chromatic dispersion phenomenon, adjustable device to eliminate. (8) screening ended, turn off the power 1, anti-pollution. 2, mold change. 3, anti-vibration. 4, anti-corrosion. 5, anti-temperature 6, anti-static DLP Projector Sepecification.png If you are looking for the original portable mini pocket dlp projector with waterproof speaker, Rich Technology must be your best choice.
