Abstract
The utility model provides a miniature projector which comprises a housing, a projection unit, a light-emitting unit and batteries, wherein the light-emitting unit is connected with the batteries and arranged on the housing, and the projection unit is positioned on the front side of the light-emitting unit. A projection part comprises a large convex lens, a small convex lens and a transparent sheet which is printed with patterns, the small convex lens and the large convex lens are respectively fixed in the emitting direction of light rays of an electric source, the transparent sheet is positioned between the two convex lenses and attached to the small convex lens, and the large convex lens and the small convex lens are both half convex lenses. Furthermore, the light-emitting unit uses an LED light-emitting component. The utility model has the advantages of small volume, convenient preservation portability and convenient operation, besides, the utility model can be used as key buckles or necklace hanging pendants.
Description
Technical field
The utility model relates to a kind of projector, particularly a kind of micro projection device.
Background technology
The micro projection device is a kind of projection head that is printed on the clear glass or the plastic sheet of pattern of placing before light source, and projection goes out clear glass or the pattern above the plastic sheet on irradiated object.The unobstructed volume of this class projector is less, how as toy or be used for decorating.
Micro projection device on the market all is the light source generating means of a little torch tubular and figuratum clear glass or the plastic sheet that is installed in the light ejecting end usually, this micro projection device is owing to adopted isolating construction, so can change figuratum clear glass or plastic sheet, to produce different projection pattern.
But also there is unsettled situation in this class separated structures, i.e. the branch defection of projection head and light source generating means causes losing of projection head or damages.And because the raising of manufacturing technology now, the cost of this class micro projection device is very cheap, does not need the shared light source generating means of a plurality of projection head.
Summary of the invention
The purpose of this utility model provides and a kind ofly can effectively overcome the novel integrated micro projection device that the problems referred to above take place, and it is small and exquisite that it is convenient to volume, and keeping and carrying can be as key chain or necklace pendant, and uses suitable convenience.
The purpose of this utility model is achieved in that it includes shell, projecting cell, luminescence unit and battery, luminescence unit connects battery and is installed in the shell, projecting cell is positioned at luminescence unit the place ahead, its improvement is: projection part includes large and small two convex lens and is printed on the slide of pattern, the light that little convex lens and big convex lens are fixed on light source successively penetrates on the direction, slide is positioned at the centre of two convex lens and the little convex lens of fitting, and large and small two convex lens are semi-convex lens; Luminescence unit adopts the LED luminescence component;
In the said structure, the LED luminescence component includes positioning head, circuit board, switch, battery compartment and the button of LED and fixed L ED, wherein LED, switch are fixed on the circuit board, and button is to inductive switch and be positioned on the shell, and battery compartment is stuck on the circuit board by the draw-in groove of bottom;
In the said structure, contact with spring between circuit board and the battery.
