Embodiment Construction

[0024] Embodiments of the infrared interactive remote control device of the present invention are as follows figure 1 As shown, the infrared interactive remote control device 400 includes a casing 401 , and a power supply 402 , a visible light source 403 , and an infrared light source 404 are installed in the casing 401 .

[0025] The power supply 402 is a battery, and can also be connected to an external power supply during specific implementation. In terms of circuit, the power supply 402 is connected to the visible light source 403 through the first switch unit 405, and connected to the infrared light source 404 through the second switch unit 406; that is to say, the two light sources are controlled by two switches and work independently. During specific implementation, the power supply 402 can also be connected to the infrared light source 404 via the first switch unit 405 first, and then the second switch unit 406. At this time, the first switch unit 405 is equivalent to ...

Abstract

Provided are an infrared interactive remote control device (400) and a projection system using same, which can distinguish an indication state and an interactive control state. A pattern disc (411) which can rotate around a rotating shaft is provided in the infrared interactive remote control device (400), and in a normal state, a visible light source (403) works independently, and indication pattern holes (4112) in the pattern disc (411) are positioned on an optical path to allow visible light (431) to pass through, so that indication light spots corresponding to the indication pattern holes (4112) are formed. When a control button (406) is pressed down, the visible light source (403) and an infrared light source (404) work together, and the control button (406) synchronously drives the pattern disc (411) to rotate, so that the control pattern holes (4112) are positioned on the optical path to allow at least the visible light (431) to pass through, and control light spots corresponding to the control pattern holes (4112) are formed to indicate that the device is currently in an interactive control state.

Description

technical field [0001] The present invention relates to a projection system, more specifically, to an infrared interactive remote control device for the projection system and a projection system using the device. Background technique [0002] In the patent with the publication number CN101833385A, a "remote control interactive pen and its receiver" is disclosed. In the remote control interactive pen, the visible light laser module emits visible light, so that the operator can accurately know the position and trajectory of the interactive pen, and freely Control the movement of the interactive pen; the infrared laser module emits infrared light, and the receiver detects its projected position, and converts the position information into a mouse signal for interactive operation. [0003] However, in this kind of remote control interactive pen, no matter whether the infrared laser module is activated or not, the light spot formed by the visible light emitted by the visible light...
