Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with attached drawing, a kind of new type auto focusing LED projector, including shell, it is characterised in that: described shell one end is set
There is adjustable camera lens 1, side inner wall is equipped with LED light 2, and the enclosure interior is located at adjustable 1 rear end of camera lens equipped with reflective mirror 3, institute
3 rear end of reflective mirror is stated equipped with power supply 4, the power supply 4 is equipped with internal battery 5,3 side of reflective mirror luxuriant and rich with fragrance alunite before being successively arranged
That lens 6, LCD screen 7 and rear Fresnel Lenses 8,7 end of LCD screen are equipped with radiator fan 9, and the LED light 2 is equipped with poly-
Light heat dissipation light shield 10 is equipped with high borosilicate heat dissipation magnifying glass 11 between the optically focused heat dissipation light shield 10 and rear Fresnel Lenses 8, described
2 side of LED light is equipped with radiator 12.
1 side of adjustable camera lens is equipped with gear micro-regulation motor 13, and adjustable 1 side of camera lens is engaged in gear micro-regulation electricity
Machine 13, adjustable 1 two sides of camera lens are equipped with balancing pole 14.
The shell is equipped with heat release hole 15.
The LED light 2, radiator fan 9, radiator 12, gear micro-regulation motor 13 are electrically connected to power supply 4.
Backlight is focused on high borosilicate heat dissipation magnifying glass through optically focused heat dissipation light shield and is carried out by the LED lamplight of the utility model
The amplification of first time backlight amplifies carrying out second with rear Fresnel Lenses, uniformly light-emitting area is amplified close to LCD and is shown
The size of screen, to reach the brightness for improving picture surrounding.To prevent LCD display and the excessively high situation of LED light source temperature,
Radiator, high borosilicate heat dissipation magnifying glass are mounted with inside projector, optically focused heat dissipation light shield and radiator fan form air cooling system.
Fan radiates to radiator against radiator air outlet, and air inlet is placed on the air duct of optically focused heat dissipation light shield to LED light
