Light emitting tube of projector light source system, projector light source system and projector

Abstract

The invention is suitable for the field of projection display and provides a light emergent pipe of a projection light source system. A plurality of transparent OLED (Organic Light Emitting Diode) luminous panels are laminated inside the light emergent pipe along the axial direction of the light emergent pipe. According to the invention, a plurality of transparent OLED luminous panels are laminated inside the light emergent pipe along the axial direction of the emergent pipe, so that light emitted by each OLED luminous panel can pass through the front luminous panels or pass through the front luminous panels after being reflected by the inner wall of the light emergent pipe and is finally projected onto a receiving surface. The OLED luminous panels have transparency and high brightness and visibility, and thus, when a plurality of OLED luminous panels are laminated, the light output can be increased and the transverse luminous surface also cannot be increased, so that not only the brightness of the projection light is improved, but also the lamination of the OLED luminous panels is beneficial for reducing the volume of a light source system. Moreover, OLEDs have low requirement on voltage and are easy to save electricity and the cost can be saved; and the light emergent pipe has the advantages of light weight, low thickness and simple structure and is also beneficial for reducing the weight and the volume of a projector.

Description

technical field [0001] The invention belongs to the field of projection display, and in particular relates to a light outlet tube of a projector light source system, a projector light source system and a projector. Background technique [0002] Most of the light sources of traditional projectors are light bulbs, which consume a lot of power and generate a lot of heat. After shutting down, the power cannot be turned off immediately, and the fan needs to continue to dissipate heat for a period of time. In the past two years, LED light sources have opened up a new development path for the future of projectors, which have the characteristics of long service life, low energy consumption, wide color gamut, and fast response. However, LED light source projectors still face a big dilemma, that is, the problem of insufficient brightness. The brightness of projection products depends most intuitively on the brightness of LEDs. Even if high-brightness LED light sources are used, the b...

Problems solved by technology

However, increasing the light-emitting area requires a large-area compound eye and collector with higher requirements, and heat dissipation is also a major problem

Therefore, ordinary LED light sources are difficult to meet the high brightness requirements of projectors for light sources.
