Abstract
The utility model is suitable for the technical field of displaying and provides a lighting module, a backlight device comprising the lighting module and an image display system adopting the backlight device. The lighting module comprises a light source and a plurality of lenses sequentially arranged along the optical axis of the light source and adjustable in movement. The lighting module is provided with the plurality of lenses sequentially arranged along the optical axis of the light source, and the lenses are adjustable in movement to change distance between the lenses, so that outgoing angle of light emitted by the light source and passing through the lenses is adjustable to be suitable for display screens with different sizes. Generality is high. Therefore, the backlight device using the lighting module is widely used in various image display systems and low in cost.
Description
Technical field
The utility model belongs to the Display Technique field, relates in particular to a kind of light emitting module, back lighting device and image display system.
Background technology
Back lighting device is as the image display system important component part, and development in recent years is rapid.Yet existing back lighting device versatility is not strong, and the back lighting device that need develop a kind of specification such as a class display screen is strictly supporting with it.Particularly in New Product Development Process, more because of the type of developing, each type is equipped with a kind of back lighting device, so causes the resource serious waste.In addition, because of backlight when causing the display system fault, maintenance after needing will whole back lighting device to split, the inconvenience of display system follow-up maintenance.
The utility model content
The back lighting device that the purpose of the utility model embodiment is to provide a kind of light emitting module and uses this light emitting module is intended to solve the existing poor problem of back lighting device versatility.
The utility model embodiment is achieved in that a kind of light emitting module, comprises that light source and a plurality of optical axis along described light source set gradually, and mobile adjustable lens.
Another purpose of the utility model embodiment is to provide a kind of back lighting device, and described back lighting device comprises above-mentioned light emitting module and movement power supply.
Another purpose of the utility model embodiment is to provide a kind of image display system, and described image display system adopts above-mentioned back lighting device.
Light emitting module in the utility model embodiment back lighting device sets gradually a plurality of lens along the optical axis of light source, and make it mobile adjustable, change thus the distance between each lens, the light that sends of light source is adjustable via the angle of each lens outgoing like this, the display screen of itself and different size is adapted, and versatility is extremely strong.Thereby this back lighting device can be widely used in various image display systems, and cost is extremely low.
Description of drawings
Fig. 1 is the structure chart of the light emitting module that provides of the utility model embodiment;
Fig. 2 is the structure chart of the image display system that provides of the utility model embodiment.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The light emitting module of the utility model embodiment sets gradually a plurality of lens along the optical axis of light source, and makes it mobile adjustable, change thus the distance between each lens, the light that sends of light source is adjustable via the angle of each lens outgoing like this, and the display screen of itself and different size is adapted, and versatility is extremely strong.
Below in conjunction with specific embodiment realization of the present utility model is described in detail.
As shown in Figure 1, the light emitting module in the back lighting device that the utility model embodiment provides comprises that light source 1 and three optical axises along described light source 1 set gradually, and mobile adjustable lens 2.Can change thus the distance between each lens 2, the light that sends of light source 1 is adjustable through the angle of each lens 2 outgoing like this, and the display screen of itself and different size is adapted, and versatility is extremely strong.Particularly in New Product Development Process, by regulating the distance between each lens 2 in this light emitting module, make back lighting device and different type of machines supporting, can save ample resources.
Usually, each lens 2 size is different, and along the light direction of described light source 1, described lens 2 are regularly arranged from small to large, are beneficial to the optimization distribution curve flux.Wherein, described lens 2 are preferably concavees lens, so that even back.For ease of adjusting backlight luminance, described light source 1 is preferably the adjustable LED of drive current.In addition, can be in the plane of incidence and the exit facet plating anti-reflection film of each lens 2, to strengthen backlight illumination.
The back lighting device that the utility model embodiment provides also comprises the movement power supply, thereby realizes modularized design, designs more flexible.Described back lighting device is provided with to regulate the adjusting knob of distance between each lens, is used for regulating size backlight.
As shown in Figure 2, the image display system that the utility model embodiment provides adopts above-mentioned back lighting device, bright dipping side in described back lighting device is provided with the display screen 3 that adapts with its rising angle and brightness, can regulate the distance of 2 on described light emitting module 4 interior each lens this moment, the light that sends of light source 1 is adjustable via the angle of each lens 2 outgoing like this, and then make the area that is projected to display screen 3 adjustable, namely the size of back lighting device emergent light area and display screen adapts.Display screen described herein 3 is for being independent of the LCDs of back lighting device, this back lighting device and LCDs 3 can separate carrying during volume production like this, can sell after assembling in the sales field, and saving is stored in a warehouse and cost of transportation.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
