Abstract: An imaging module includes a reflective display element, a prism device and a light absorbing element. The reflective display element includes a reflective display surface. The prism device includes first and second prisms. The first prism includes first, second and third surfaces. The second prism includes fourth, fifth and sixth surfaces. A stray light beam is incident into the first prism, passes through the third surface and then exits the first prism, then the stray light beam is incident into the second prism through the fourth surface, and then the stray light beam is reflected by the fifth surface and then exits the second prism. The light absorbing element is disposed on a transmission path of the stray light beam exiting the second prism. A projection device including the imaging module is also provided.

Abstract: The present invention provides a temperature sensing light-emitting device, applicable for use in electronic devices, and is structured from a temperature sensing element, a processing unit, a display element, and a voice unit. The temperature sensing element is used to sense the temperature of the area under measurement, after which the electrically connected processing unit determines the measured temperature. The present invention is characterized in that the processing unit is connected to the display element, thereby enabling the measured temperature to be visually displayed for the user; and the temperature sensing element is used to sense the temperature of the area under measurement after which the processing unit determines the temperature range of the area under measurement to adjust the display element to display different color lights, thereby enabling the user to easily determine the temperature of the area under measurement.
