Abstract
The invention discloses a dustproof cover for a projector color wheel. The dustproof cover is characterized by comprising an aluminum alloy cover body (1) which can partially cover the color wheel, wherein the aluminum alloy cover body (1) is provided with an arc part (2) and a square part (3) which are matched with the color wheel in appearance; and the aluminum alloy cover body (1) is in positioned connection with the inside of a projector. After the dustproof cover is arranged on the color wheel for use, dust can be prevented from entering into a light channel of the projector and the pollution to a light path is avoided; and in addition, the damage to elements due to high temperature when the projector works can be avoided and effective heat dissipating can be realized.
Description
Technical field
The invention belongs to projector's accessory, be specifically related to a kind of color wheel of projecting camera dust cover.
Background technology
In recent years, projector's technology is more and more universal, has been widely used in the fields such as teaching, scientific research and amusement.Projector adopts has powerful light source as projection source; therefore thermal value is very large; avoid high temperature for the protection component and damage, generally can offer large air inlet, and adopt the device such as fan to force air intake; improve the radiating efficiency of projector; but so all be very easy to bring the dust in outside air into projector inside, if these dusts enter optical channel, will have a strong impact on the image quality of projector; and cause failure rate to raise, reduce serviceable life etc.
Colour wheel is a kind of accessory of projector inside, is the device nearest apart from the optical channel entrance of projector, so the dust that accumulates above of colour wheel is very easy to enter optical channel when starting in projector, pollutes light path system.
Summary of the invention
The invention provides a kind of color wheel of projecting camera dust cover, after being arranged on colour wheel, can prevent that dust from entering the projector light passage, avoids the pollution of light path; And damage component because of high temperature in the time of can avoiding projector's work, namely can efficiently radiates heat.
For achieving the above object, the technical solution used in the present invention is: a kind of color wheel of projecting camera dust cover, but the aluminium alloy cover body that comprises a partial coverage colour wheel, this aluminium alloy cover body has curved portions and the square department that matches with the colour wheel profile, and described aluminium alloy cover body is connected with the projector positioned internal.
Further, offer positioning screw hole on described aluminium alloy cover body, be connected with the projector positioned internal through screw.
Further, described aluminium alloy cover body is provided with some aluminium alloy radiating fins, and this aluminium alloy radiating fin has hollow cavity, and the hollow cavity of aluminium alloy radiating fin is communicated with the cover inner chamber of described aluminium alloy cover body.
Further, the surface of described aluminium alloy cover body has electricity work layer.
Characteristics of the present invention are: by at the outside dust cover of installing of color wheel of projecting camera, can avoid the dust accumulation of colour wheel, be subjected to contamination by dust and affect image quality with the light path of avoiding projector, can extend the serviceable life of projector.Aluminum alloy material has high thermal conductivity coefficient, heat conduction is fast, it is good heat sink material, can avoid accumulation of heat, and density is little, lightweight, the aluminium alloy radiating fin that coordinates large surface, around namely the heat of colour wheel can being conducted rapidly and be dispersed into, then be dispersed into rapidly in surrounding air through projector's body cooling system, strengthen radiating effect.The electricity work layer of aluminum_alloy cover surface can strengthen resistance to elevated temperatures, increases the service life.
