Abstract
The utility model provides a radium -shine device based on wave lens, radium -shine device includes a laser diode LD subassembly, a laser diode LD drive circuit and an integration ya keli leaded light subassembly, laser diode LD drive circuit is connected with the laser diode LD subassembly, integration ya keli leaded light subassembly includes: two wave lenses and a semi -reflector, two vertical symmetries of wave lens set up, the tip of two wave lenses is connected and integrated into one piece, semi -reflector sets up between the tip of two wave lenses, the laser diode LD subassembly lies in integrated ya keli leaded light subassembly one side. The utility model discloses a stray light yield of radium -shine device is little, and device thickness is little, like this can be easy to assemble on the blank on narrow limit, and can not shelter from projection light, and can not form the shade on the blank, improved the installation convenience of radium -shine module like this.
Description
Technical field
The utility model relates to projector's technical field, particularly a kind of laser apparatus based on wave eyeglass.
Background technology
In electronic whiteboard, radium-shine module is all arranged at above electronic whiteboard, exhale laser light by radium-shine module like this and form laser light curtain, user uses hand or pen can block laser light curtain when the enterprising line operate of blank, the position of the laser light curtain be now blocked can reflect IR light, this luminous point is caught by interactive projector and after extract location information, can realize drawing function alternately.
When but existing radium-shine module is arranged on blank, need with projection image edge the distance reserving 5-10cm, cause projection image to maximize like this.And existing radium-shine module is too thick, be unfavorable for being installed on the blank on narrow limit, and if due to the thicker too close picture of radium-shine module, will throw light be blocked, blank formed shade, be unfavorable for the normal display of screen on blank; In addition, existing radium-shine module parasitic light is too strong, if too close projection image, will cause user's misoperation.Therefore, existing radium-shine module needs to be modified.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of laser apparatus based on wave eyeglass, and this laser apparatus parasitic light exports little, device thickness is little, on such blank that can be easily installed in narrow limit, and can not throw light be blocked, shade can not be formed on blank.
The utility model is achieved in that a kind of laser apparatus based on wave eyeglass, described laser apparatus comprises a laser diode LD assembly, a laser diode LD driving circuit and an integrated acrylic leaded light component, and described laser diode LD driving circuit is connected with laser diode LD assembly; Described integrated acrylic leaded light component comprises: two wave eyeglasses and a half-reflecting mirror; Described two wave eyeglasses are vertically symmetrical arranged, and the end of described two wave eyeglasses is connected and one-body molded; Described half-reflecting mirror is arranged between the end of two wave eyeglasses; Described laser diode LD assembly is positioned at integrated acrylic leaded light component side.
Further, the angle of described two one-body molded formation of wave eyeglass is 80 ~ 100 degree.
Further, described wave eyeglass is a wordline wave eyeglass.
The utility model has the advantage of: this laser apparatus comprises a laser diode LD assembly, a laser diode LD driving circuit and an integrated acrylic leaded light component; Because these parts are little, the laser apparatus of formation is less than existing radium-shine module, thus can be easily installed on the blank on narrow limit, and can not block throw light, can not form shade on blank.Laser apparatus of the present utility model is that the light sent by laser diode LD assembly is exhaled by wave eyeglass, and the parasitic light exported like this is little, and uniform light.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is overlooked.
Fig. 2 is the utility model using state structural representation.
Embodiment
Refer to shown in Fig. 1 and Fig. 2, a kind of laser apparatus based on wave eyeglass of the present utility model, described laser apparatus comprises laser diode LD assembly 1, laser diode LD driving circuit 2 and an integrated acrylic leaded light component 3, and described laser diode LD driving circuit 2 is connected with laser diode LD assembly 1; Described integrated acrylic leaded light component 3 comprises: two wave eyeglasses 31 and a half-reflecting mirror 32; Described two wave eyeglasses 31 are vertically symmetrical arranged, and the end of described two wave eyeglasses 31 is connected and one-body molded; Described half-reflecting mirror 32 is arranged between the end of two wave eyeglasses 31; Described laser diode LD assembly 1 is positioned at integrated acrylic leaded light component 3 side.(this laser diode LD assembly 1 can be positioned at the left side of integrated acrylic leaded light component, or right side).The light source that this laser diode LD assembly 1 sends impinges upon on a wave eyeglass 31 through half-reflecting mirror 32 later half light source, impinges upon on another wave eyeglass after the reflection of half light source.A laser diode LD assembly 1 and a laser diode LD driving circuit 2 is so only needed to greatly reduce manufacturing cost.Wave eyeglass 31 described in this is a wordline wave eyeglass.
In the utility model, the included angle A of described two one-body molded formation of wave eyeglass 31 is 80 ~ 100 degree.This angle is preferably 90 degree.
In a word, the utility model shortens the distance at laser apparatus and projection image edge, thus can not affect the display of the screen of blank; It is eliminated, weaken the parasitic light exported, and thickness is little, the uniform light sent.
Although the foregoing describe embodiment of the present utility model; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present utility model; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present utility model and change, should be encompassed in scope that claim of the present utility model protects.
