Problems solved by technology

However, heat is generated when the excitation light source excites the phosphor powder, which increases the temperature of the color wheel. The greater the energy of the excitation light source, the higher the temperature generated by the color wheel. If the temperature is too high, the color wheel cannot work normally. As people's requirements for brightness increase, the energy to excite the light source will increase. Therefore, how to control the temperature of the color wheel and make it operate normally under the premise of high brightness is the key to the light source technology.

Embodiment 1

[0015] figure 1 Shown is a side view of the high-efficiency heat dissipation color wheel of this embodiment, figure 2 Shown is the front view of the high-efficiency heat dissipation color wheel of this embodiment. A high-efficiency heat-dissipating color wheel that separates the double-sided excitation color wheel on two substrates so that the two substrates are connected to a fixed rotating shaft with a gap. As a result, the heat borne by one double-sided excitation color wheel in the past can be dispersed to the two substrates, and the heat generated by the excitation of the phosphor region can be quickly dissipated, so that the color wheel always maintains normal operation. In addition, the rotating shaft includes a driving shaft 100 and a driven shaft 101, the two substrates are the first substrate 200 and the second substrate 201, and a nano heat dissipation coating layer 300 is provided on the part outside the working area of ​​the two substrates. In addition, the heat d...

Abstract

The invention provides a high-efficiency heat-radiation color wheel comprising a first substrate, a second substrate, and a rotating shaft. The first substrate is parallel with the second substrate and the first substrate and the second substrate are connected by the rotating shaft. The first substrate includes a first working ring arranged at one side, far away from the second substrate, of the first substrate; and the second substrate includes a second working ring arranged at one side, far away from the first substrate, of the second substrate. According to the invention, a dual-sided exciting color wheel is separated at the two substrates and a non-working zone and a driving shaft or / and a driven shaft are plated with nano thermal dissipating materials or a thermal insulation material is arranged for filling to increase a radiation cooling area, so that dissipation of heat generated by excitation of a fluorescence region can be accelerated and thus the color wheel can work normally all the time.

Description

Technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a color wheel with efficient heat dissipation. Background technique [0002] The color wheel is generally used in an illuminating device or a projection device as an optical spectroscopic unit, which is driven by the driving unit to rotate, so that the different color areas on the color wheel correspond to the light emitted by the light source and then generate the corresponding color of light to achieve spectroscopy Effect. However, as the excitation light source excites the phosphors, heat is generated at the same time, which increases the temperature of the color wheel. The greater the energy of the excitation light source, the higher the temperature generated by the color wheel. Excessive temperature will make the color wheel unable to work normally. As people's requirements for brightness increase, the energy of the excitation light source will increase. Therefore, how ...
