Detailed description of the invention
Below in conjunction with specific embodiment and Figure of description this utility model it is further elaborated and illustrates:
Embodiment one: refer to Fig. 1 and Fig. 2, a kind of projector, including LED light source 1, lens barrel 2, reflecting mirror chuck 3 and plane of reflection mirror 4, described plane of reflection mirror 4 is located on reflecting mirror chuck 3, described LED light source 1 is located at one end of lens barrel 2, and described reflecting mirror chuck 3 is located at the other end of lens barrel 2.
The first illuminating lens 7 it is provided with in described lens barrel 2, second illuminating lens 9, first imaging len 11, second imaging len 12 and short in size screen 14, it is provided with the first spacer ring 9 between described first illuminating lens 7 and the second illuminating lens 8, it is provided with the second spacer ring 13 between described first imaging len 11 and the second imaging len 12, described short in size screen 14 is located between the second illuminating lens 8 and the first imaging len 11, the aluminium base 5 of described LED light source 1 is located at the end of lens barrel 2, near the first imaging len 11, it is provided with pressing plate 6 between described aluminium base 5 and the first imaging len 11, angle formed by the imaging optical axis of described lens barrel 2 and plane of reflection mirror 4 is 160 °.
Angle formed by imaging optical axis and the plane of reflection mirror 4 of lens barrel 2 is 160 °, LED light source 1 light passes through the first illuminating lens 7 and the second illuminating lens 8, light focusing, brightness is high, image on short in size screen 14 is projected on plane of reflection mirror 4, to become the direction of 140 ° of angles to be projected on perspective plane with imaging optical axis, therefore, the projector of small size remains to meet the use demand of client.
Embodiment two: refer to Fig. 3 and Fig. 4, a kind of projector includes projecting cylinder 10 and lens barrel 20, and the axis of described projecting cylinder 10 forms an angle with the axis of lens barrel 20, and in the present embodiment, the axis of described projecting cylinder 10 is 160 ° with the angle of the axis of lens barrel 20.
The first illuminating lens 30 it is provided with in described projecting cylinder 10, second illuminating lens 40 and dot matrix screen 90, it is provided with the first spacer ring 50 between described first illuminating lens 30 and the second illuminating lens 40, one end of described projecting cylinder 10 is provided with aluminium base 100, described first illuminating lens 30 and the second illuminating lens 40 are located between dot matrix screen 90 and aluminium base 100, it is provided with pressing plate 110 between described aluminium base 100 and the first illuminating lens 30, the first imaging len 60 and the second imaging len 70 it is provided with in described lens barrel 20, it is provided with the second spacer ring 80 between described first imaging len 60 and the second imaging len 70.
Through the first illuminating lens 30 and the second illuminating lens 40 by light-ray condensing, the brightness making light strengthens, then light beam is beaten on dot matrix screen 90, the numeral of dot matrix screen 90 change time image along with changing together, owing to the angle of the axis of axis and the lens barrel 20 of described projecting cylinder 10 is 160 °, when forming an image, dot matrix screen 90 has 1/2 effectively, forms preferable image by the first imaging len 60 and the second imaging len 70, can the volume of reduced projection instrument.
Described aluminium base LED light source 100 is in the surface of illuminating lens 30.The inversely proportional adjustment with the direction of imaging lens barrel.Can make illumination brightness improve, veiling glare reduce.Imaging is clearer, then adds the preposition smooth hurdle of optics
