Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an LED projector,

The present invention relates to an LED projector which can easily adjust a position (image), and in a projector using an LED as a light source, a film mounting tube equipped with an image film is rotatably coupled to an insertion portion of an illumination tube, A support pipe provided with an IC chip having a control program and a control switch, and an illumination tube provided with an LED light source, which can control the phase of an image easily by turning the film mount tube to the left or to the right, The program integrated in the IC chip arbitrarily adjusts the projection time of the projector to arbitrarily adjust the projection time of the projector, thereby strongly attracting the attention of the people by the flashing image. A mirror mechanism is added to the projector to facilitate the projection direction of the image It can be varied.

Generally, a projector for projecting an image of a film onto a screen includes an illuminating means having a light source of high-focus light and a condenser lens for converging light rays in parallel; A film feeding means for feeding a frame, on which a film is mounted, to each of the cates provided orthogonally to the light transmission path of the light beam; And a projection means for projecting an image of the still film on the screen by a projection tube having a convex lens and projecting the projected image onto a screen.

In recent years, LED projectors have been used industrially and the LED light source is small, so the structure of the projector is simpler and smaller, and the image film containing various information is embedded in the case of the projector light tube.

An example of this kind of prior art is as follows.

An object of the present invention is to provide a light emitting diode (LED) chip, an LED chip circuit board, and a metal heat sink (not shown) A formed LED lamp; An illumination case for projecting a light beam of the LED lamp; A first lens assembled to the LED chip; And a second lens mounted on the other end of the illumination case, wherein the heat-radiating member included in one end of the illumination case includes a screw assembly part screwed into the lower end of the illumination case, So that the heat of the LED chip is dissipated.

Conventionally, a projector using a high-intensity light source is rarely used in recent years due to the complicated structure of the cooling water stage for cooling the high temperature of the light source, the means for supplying the film, and the like.

On the other hand, in the conventional projector described above, since the frame on which the film is mounted is always mounted in the correct phase in the vertical direction, the image is not tilted or projected backwards on the screen.

However, since a projector using an LED light source has a circular image film built in most of the case of the lighting tube, if the phase of the image film is not properly built in, the image is projected on the screen.

That is, in the LED lighting device of the prior art, a film of an image is embedded between the first and second divided pipes 21 and 22, and the first divided pipe 21 and the second divided light 22 are screwed However, it is difficult to adjust the image in the vertical direction when the phase of the image projected on the screen is inclined in either direction.

Therefore, the image film must be properly built in from the beginning so that the phase of the image film can be in the longitudinal direction. Since the film that is in contact with the end portion of the middle dividing tube, to which the first division tube 21 for fixing the film is screwed, There is a problem that it is difficult to maintain the projected image of the film correctly.

Also, since the third division tube 23 equipped with the projection lens is screwed to the inside of the second division tube 21 for fixing the film, the third division tube 23 The second dividing tube 22 exposed to the outside is also twisted together and the pressing force of the film is relaxed so that the image on the screen is not clear due to the displacement of the film, (fog) is formed.

An object of the present invention is to provide an LED projector for enlarging and projecting an image of a film, in which an image film can be securely mounted inside a projector, and when an image projected on a screen is lengthened or inverted according to the phase of the built- And a phase adjustable LED projector capable of easily adjusting a phase of an image by a mounting tube.
