Embodiment
In order to make technical matters solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of projector, comprise the housing 1, light engine 2 and the radiating module that are provided with air inlet and air outlet, described light engine 2 is fixed in housing 1, the side of described light engine 2 is provided with LED light source, described radiating module comprises multiple heating radiator and fan, and described heating radiator contacts with LED light source face.
Described housing 1, for having the rectangular parallelepiped of hollow structure, comprises the first side wall 11, four sidewall 14 relative with the first side wall 11 and the second sidewall 12 be connected with the 4th sidewall 14 with the first side wall 11 respectively and the 3rd sidewall 13.The sidewall of housing 1 has the ventilating opening of lattice-shaped, facilitate the air in housing to circulate with extraneous, accelerate heat radiation.Particularly, described the first side wall 11 is provided with the first air inlet 111, second sidewall 12 and is provided with air outlet 121, and the 3rd sidewall 13 is provided with the second air inlet 131.
Described fan comprises the first fan 41 and the second fan 42, and described heating radiator comprises the first heating radiator 31, second heating radiator 32 and the 3rd heating radiator 33.In the present embodiment, the first fan 41 is near air outlet 121, and the second fan 42 is near the first air inlet 111; Described first heating radiator 31 is between the first fan 41 and the second air inlet 131, and the second heating radiator 32 is between the first fan 41 and the second fan 42, and close air outlet 121; Described 3rd heating radiator 33 is near the second fan 42.
The side of described light engine 2 is provided with LED light source, described LED light source comprises red-light LED 21, green light LED 22 and blue-ray LED 23, described red-light LED 21 and blue-ray LED 23 are oppositely arranged, and red-light LED 21 is adjacent to the 4th sidewall 14, and blue-ray LED 23 is adjacent to the first side wall 11; Described green light LED 22, between red-light LED 21 and blue-ray LED 23, is adjacent to the second sidewall 12.
Particularly, the first heating radiator 31 contacts with red-light LED 21, and the second heating radiator 32 contacts with green light LED 22, and the 3rd heating radiator 33 contacts with blue-ray LED 23.The area of dissipation of described first heating radiator 31 is greater than the area of dissipation of the 3rd heating radiator 33, and the area of dissipation of described second heating radiator 32 is greater than the area of dissipation of the 3rd heating radiator 33.Because when red-light LED 21 and green light LED 22 work, thermal value is larger, the area of dissipation of its heating radiator can be increased to strengthen heat radiation, and blue-ray LED 23 when working thermal value less, the heating radiator of less area of dissipation can be used, targeted design like this, the radiating efficiency of heating radiator can be avoided not enough or superfluous, simultaneously by the rational deployment of heating radiator, reduce the volume of projector.
Described projector also includes driving circuit 5 and camera lens 6, described driving circuit 5 near the first heating radiator 31, for the work of the parts such as control both optical engine 2 and fan.The first side wall 11 of housing 1 is provided with camera aperture, and described camera lens 6 is arranged in camera aperture, and is connected with light engine 2.
As shown in Figure 2, during projector's work, LED light source produces amount of heat and passes to the heating radiator contacted with it, and the first fan 41 and the second fan 42 work and drive air in housing 1 to accelerate flowing, so that the heat in heating radiator is delivered to the external world rapidly.As shown in phantom in Figure 2, air inlet, heating radiator, fan and air outlet form heat dissipation wind channel, and described heat dissipation wind channel comprises the first heat dissipation wind channel a and the second heat dissipation wind channel b.Air flows into from the second air inlet 131 under the effect of the first fan 41, flows through the first heating radiator 31 and takes away heat, then flow out from air outlet 121 through the first fan 41, and this is the first heat dissipation wind channel a; Air flows into from the first air inlet 111 under the second fan 42 acts on, and take away heat through the 3rd heating radiator 33 and the second heating radiator 32, then discharge from air outlet 121, this is the second heat dissipation wind channel b.Especially, between the first fan 41 and the second heating radiator 32, be provided with baffle plate 35, the air-flow flowing through the second heating radiator 32 can not be mixed mutually with the air-flow in the first heat dissipation wind channel a, in case reduce the heat dispersion of projector.
Red-light LED 21 and green light LED 22 because of power higher, the heat produced is more, so placed toward the first heating radiator 31 by the first fan 41, is placed by the second fan 42 toward the second heating radiator 32, with to the first heating radiator 31 and the second heating radiator 32 directly blow flow, accelerate heat radiation; And for blue-ray LED 23 because thermal value is less, in the present embodiment, preferably, by a part for the 3rd heating radiator 33 radiating surface toward the second fan 42, under the effect of the second fan 42, air can be driven to flow into from the second air inlet 131, take away heat through the 3rd heating radiator 33, thus make the second fan 42 play the object of auxiliary heat dissipation to the 3rd heating radiator 33.
Especially, because LED light source needs larger current to drive, therefore driving circuit 5 has larger current and flows through, and produces and be enough to heat affect circuit block, so part also needs to dispel the heat.Described driving circuit 5 and the first heating radiator 31 are contiguous, and are just in time arranged in the first heat dissipation wind channel a, the heat making the air-flow in air channel take away driving circuit 5 to distribute.Design like this, can dispel the heat to red-light LED 21, can take into account again the heat radiation of driving circuit 5, reasonably the inner space of application projector, makes projector microminiaturized, improves heat dispersion simultaneously.
Preferably, in the present embodiment, described heating radiator also comprises the 4th heating radiator 34, near the second air inlet 131, its role is to the heat dispersion improving projector further.
In sum, projector provided by the invention is by rational layout L ED light source and the radiating module with LED light source adaptation, projector is made to have compact conformation, advantage that volume is little, there is good heat dispersion simultaneously, be of value to the work of this projector's long-term stability, extend the life-span of projector.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
