Description
Technical Field
The utility model belongs to the technical field of the projection, specifically speaking relates to a light converter heat radiation structure.
Background
The optical converter of the existing projector, i.e. the fluorescent wheel, adopts a mode of combining a wavelength conversion element and a solid heat dissipation structure. The solid-state heat dissipation structure adopts a metal heat dissipation structure and combines with the back fins to realize heat dissipation, and meanwhile, the irradiation position is replaced by the rotation or displacement driven by the motor, so that the purpose of uniformly distributing the heat generated by the exciting light on the wavelength conversion element is achieved.
However, the existing metal heat dissipation structure cannot transmit light, the wavelength conversion layer can only receive single-side exciting light, the efficiency is low, and the excited brightness is not high enough. Because of the heat dissipation problem, the heat generated by the excitation light needs to be uniformly distributed on the wavelength conversion element by means of rotation or displacement, which requires the introduction of some power-providing elements, and thus the structure is more complicated.

Further, the support layer further comprises an optical filter coating film 3; the filter coating film 3 is arranged between the heat dissipation fluid layer 2 and the wavelength conversion layer 1. According to the structure, the optical filter coating film 3 isolates the heat dissipation fluid layer 2 from the wavelength conversion layer 1, the optical filter coating film 3 is extremely thin, heat generated by the wavelength conversion layer 1 is firstly diffused to the optical filter coating film 3, and then the optical filter coating film 3 quickly diffuses the heat to the heat dissipation fluid layer 2, so that the wavelength conversion layer 1 can uniformly dissipate heat. The exciting light irradiates from the front surface of the wavelength conversion layer 1 to generate excited light, and due to the existence of the filter coating film 3, part of the excited light is reflected by the filter coating film 3, so that the dissipation of the excited light is reduced, and the brightness power of the excited light is increased.
Further, the support layer also comprises a separation layer 4; the heat dissipation fluid layer 2 is arranged between the isolation layer 4 and the optical filter coating film 3. As can be seen from the above structure, the spacer layer 4 and the filter coating film 3 define the flow area of the heat sink fluid layer 2.
Further, the filter coating film 3, the heat dissipation fluid layer 2 and the isolation layer 4 can transmit excitation light. According to the structure, the optical filter coating film 3, the heat dissipation fluid layer 2 and the isolation layer 4 can transmit exciting light, so that the exciting light on the back can sequentially pass through the isolation layer 4, the heat dissipation fluid layer 2 and the optical filter coating film 3 to reach the back of the wavelength conversion layer 1 to generate excited light; part of the excited light is reflected by the filter coating 3, and the brightness power of the excited light is increased. Thus, the wavelength conversion layer 1 can receive the excitation light from multiple surfaces, and the generated excitation light and the light reflected by the filter coating film 3 are emitted together, so that the luminous efficiency is improved. The heat dissipation fluid layer 2 can adopt transparent gas or liquid as heat exchange fluid, and the isolation layer 4 can adopt transparent materials such as glass and the like.
Further, the filter coating film 3 may reflect the excitation light. As can be seen from the above structure, part of the excited light is reflected by the filter coating film 3, increasing the luminance power of the excited light.
Further, the wavelength conversion layer 1 is arranged on the surface of the optical filter coating film 3; the optical filter coating film 3 and the isolation layer 4 coat the heat dissipation fluid layer 2. As can be seen from the above structure, the spacer layer 4 and the filter coating film 3 define the flow area of the heat sink fluid layer 2.
Further, a total reflection mirror surface 5 is arranged at the edge of the heat dissipation fluid layer 2; the total reflection mirror 5 is used to change the direction of the excitation light incident from the edge. As can be seen from the above structure, due to the limitation of the design space, sometimes the excitation light cannot be incident from the direction perpendicular to the filter coating film 3, and often enters from the edge side of the heat dissipation fluid layer 2, at this time, because the edge of the heat dissipation fluid layer 2 is provided with the total reflection mirror 5, the excitation light is emitted to the total reflection mirror 5 and then reflected to the filter coating film 3.
Further, the excitation light incident from the edge reflected by the total reflection mirror 5 is vertically emitted to the filter coating 3.
