Problems solved by technology

Such a complicated design process wastes a lot of time and energy, and re-making a new optical machine increases the cost of designing and changing the light source
In addition, since the traditional optical components are not replaceable, when the optical components are worn out, the fixed optical components make the maintenance work extraordinarily difficult

[0032] Figure 6 A schematic diagram of an optical path of a projector according to a second embodiment of the present invention is shown. Please also refer tofigure 1 and Figure 6 The difference between the projector 200 of this embodiment and the projector 100 of the first embodiment is that the projector 100 of the first embodiment is a two-lamp projector, while the projector 200 of this embodiment is a single-lamp projector machine. More specifically, since the light source module 104 in the projector 100 with two lamps can be replaced as a whole, the projector 200 of this embodiment can include the same cabinet 102 and light source as the projector 100 of the first embodiment. machine 106, and only replace the light source module 104 with double lamps with the light source module 204 with single lamp. Therefore, the projectors with different light source modules can use the same light engine without additionally designing and changing the light engine to match differe...

Abstract

The invention discloses a projection machine which comprises a light source module and an optical machine. The light source module includes a fixing base, at least one light source and light beam leading components. The light source is fixed on the base for generating light beam. The light beam leading components are installed on the base and are near by the light source for changing forwarding direction of light beam. The optical machine is installed nearby the light source module for receiving light beam from the light beam leading components and generating images. The fixing base can be equipped on the projection machine with changeable type to make the light source changeable for the projection machine.

Description

technical field [0001] The invention relates to a projector, in particular to a projector with a replaceable light source module. Background technique [0002] The light source of the projector is provided by the light bulb. In a traditional projector, a bulb is used to generate light, and optical components are used to change the path of the light and increase the efficiency of the light. The light engine of the projector receives the light from the bulb to generate an image and project the image onto the screen. [0003] In traditional projectors, only the bulb is a detachable component, and optical components such as convex lenses and prisms are fixedly arranged in the light engine. Therefore, when the R&D personnel want to change the design, after replacing the bulbs with different specifications, the light engine also needs to be redesigned to obtain an optical path design that matches the new light source. Such a complicated design process wastes a lot of time and e...
