Embodiment 1
[0045] Such as figure 1 As shown, a lighting device provided by Embodiment 1 includes: a support 30, and a liquid crystal display panel 40 installed on the support 30; wherein,
[0046] Such as Figure 2a-Figure 2d As shown, the liquid crystal display panel 40 is divided into a display area a and a light emitting area b;
[0047] Such as image 3 As shown, the liquid crystal display panel 40 has a first polarizer 41 on the light-incident side corresponding to the display area a and the light-emitting area b, that is, there is a first polarizer 41 on the side where the backlight module 50 emits light;
[0048] Such as image 3 As shown, the liquid crystal display panel 40 only has a second polarizer 42 on the light output side corresponding to the display area a.
[0049] In this embodiment, the lighting device is used as a wall lamp as an example for description. In specific implementation, as figure 1 As shown, the liquid crystal display panel 40 can be fixed on the wall...
Embodiment 2
[0063] The lighting device provided by Embodiment 1 of the present invention may cause light leakage in special glasses due to the viewing angle of the viewer (such as tilting the head of the viewer, etc.), or because the analyzer and the lighting device are fixed during installation. In order to enhance the display quality of the confidential content displayed on the liquid crystal display panel in the light-emitting area b by wearing special glasses or using a polarizing device, Embodiment 2 of the present invention provides a lighting device, such as figure 1 As shown, the support 30, and the liquid crystal display panel 40 installed on the support 30; wherein,
[0064] Such as Figure 2a-Figure 2d As shown, the liquid crystal display panel 40 is divided into a display area a and a light emitting area b;
[0065] Such as Figure 5 As shown, the liquid crystal display panel 40 has a first polarizer 41 on the light-incident side corresponding to the display area a and the l...

Abstract
The invention discloses an illumination device, a pair of special glasses of the illumination device, a polarization analyzer of the illumination device and an illumination system. A liquid crystal display panel serves as a lamp capable of displaying images and information, and is divided into a display area and a light emitting area. The incident side is provided with a first polarizer, a second polarizer is arranged on the area, corresponding to the display area, of the light emitting side, the light emitting area is not provided with a second polarizer, light becomes linearly polarized light through the first polarizer and then penetrates through the liquid crystal display panel to reach the light emitting area, and due to the fact that the light is not filtered through the second polarizer, information contained in the light can not be displayed in naked eye state and white light is emitted, and the liquid crystal display panel can serve as the illumination lamp. The linearly polarized light penetrates through the liquid crystal display panel to reach the display area, and due to the fact that the linearly polarized light is filtered through the second polarizer, the information contained in the linearly polarized light can be displayed in the naked eye state, and attractiveness is improved. When people watch the illumination device through the pair of the special classes or the polarization analyzer, people can see confidential information content displayed by the liquid crystal display panel due to the filtering function of the second polarizer.
Description
technical field [0001] The invention relates to the technical field of lighting, in particular to a lighting device, special glasses for the lighting, a polarization analyzer and a lighting system. Background technique [0002] As a daily consumable, lighting fixtures have undergone earth-shaking evolution with the progress of economy and society and the emergence of new light sources such as fluorescent lamps, energy-saving lamps, and LED lamps. The richness and diversity of light sources have also opened up a new page for the lighting industry. City squares, traffic roads, newly built communities, home decoration, shopping malls and office buildings, etc. all need lighting product decoration, and put forward customized requirements for lighting products. [0003] However, the current lighting products often can only realize the general lighting function, and do not have other differentiated special display functions. Contents of the invention [0004] In view of this, ...
