New description: [New technical field] A beam modulating device for a light projector, especially a barrier on the working surface of the emitter, can block unnecessary scattered light, and the working surface of the screen projector is agglomerated by the scattered light beam of each LED. And the interference of the light ray 'to the hidden work and directivity in the demand work angle to cast light, to maintain clear vision of driving. [Prior Art] Regarding the application of the emitter, in addition to the wide-angle illumination, if it is used for long-range projection, its beam must be standardized as a directivity, such as a car headlight or a light projector used in a surveillance system. Recently, due to the development of electro-optical technology, the related light-emitting equipment uses LED crystal ball as the laser element. With its innate design, it can project the generated beam according to the specification angle, and use it in the use of the remote emitter, and its The light wave itself can be modulated at different wavelengths, so the design of the LED crystal ball for the equipment used for light projection is widely used, for example, in a monitoring system, and acts on the basis of the remote light projection. Used in the monitor material, it is applied to the road condition monitor, it will be installed on the roadside of the road, to drive near the lane, to meet the needs of the nearest photography, and to meet its luminosity, the position of the light projection, the front and the car The two fundamental directions of the tail, especially in the headlights, the light beam that occurs in the light projector will affect the driver's vision at night, so its working beam must be angled in such a way that the LED crystal ball used can be utilized. The initial definition of the specification angle, but due to the LED crystal ball its laser wafer body emits light, in addition to the optical mirror specification - effective working beam, in the radial angular position, the scattered light will be reflected through the cover. For the laser working mode of the LED crystal ball, please refer to the figure j of the figure j, which is generated by a laser chip ίο 'after the driving of the current, the laser beam is generated, and the rear side is operated by a mirror 13 'the beam is single - The directional reflection is at the position of the light filament c, and the crystal ball cover η is coupled to an integral lens 12'. The laser light generated by the laser wafer 10 is directionally reflected by the mirror 13, and is modulated by the refraction of the integral lens Ϊ2. After a valid working beam Β〇, the working beam 共 is conjugated by a 3 M441128 yoke axis c to form a working angle of 0. /, the working angle ^. The size of the crucible is achieved by the pre-arrangement arrangement assisted by the mirror 13 or even the integral lens 12. The end of the crystal ball cover 11 is integrally formed with the integral lens 丨2, and the integral lens 12 is required to have a high refractive power. Therefore, the body of the crystal ball cover 11 is also generally transparent, and the light beam emitted by the laser wafer 1 射 is emitted outside through the integral lens 12, except that the integral lens 12 can perform stereotyped auxiliary modulation on the working angle, and also by reflection. The pointing reflection of the mirror 13 causes the light emitted by the laser wafer 1 to be concentrated as much as possible within the working angle range, and the mirror 13 is located at the bottom of the laser wafer H) and has the same ability to reflect at the periphery of the curvature. The reflecting surface of the edge reflects the light beam of the laser wafer 10, and the laser wafer 1 is directly linearly refracted by the crystal ball cover u_, and the two beams form a ring at the periphery of the crystal ball cover u.

It can be punctured by the LED crystal ball 1 specification _ jade angle, and the working mode of the figure ' At the projection work surface of the Guangyi 100, it will be awkward at work. The extra angles other than 2 radiate the unnecessary scattered light Bn 'and the (10) crystals are arranged on the working surface of the projection ϋ 1GG for most of the scales, so that the scattered light Bn generated by most (10) crystals will Form agglomeration, so that in addition to the power angle ❹. If there is no need for the outside, the driver often causes visual interference due to the extra scatter light Bn. If the working surface of the illuminator 100 is a V 4 corner driver, the driver will absorb the same as a square. The lights are more and the light projector is just to avoid the visual interference of the traffic in the daytime, but the light wave of infrared light is often used, but in the LED crystal ball 1, the light car, c can see the red light ball, and the Outside the angle of the angle, the driver will also misjudge the red light due to the scattered light, especially when the working surface of the light projector is circular. S1 thus affects the clear view of the driving field, or the risk of accidental lighting due to the red light, so the generation of the scattered light (10) will cause a variety of inconveniences, and if the application is 6 new light Β _ out of the age is small The device is activated to destroy the m-view function of the monitoring system. 4 M441128 [New Content] This creation is to provide a kind of device that can modulate the beam of the light projector. It is light-emitting and she enters the light-emitting emission working surface of the optical device, and the LED crystal ball of the light projector is provided with a common light. The light aperture, by which the grating blocks additional scattered light, causes the light emitted by the light emitted by the light projector to utilize the light beam. ^ This creation is again - the purpose is that the distance between the grating and the face of the emitter is adjustable by the component. /' The diameter of the mercerized hole of the third purpose of this creation may be equal to or slightly smaller than the cut-off & diameter of the LED crystal ball. The fourth object of the present invention is that the aperture has a longitudinal depth, and the body of the aperture or grating is a light absorbing function of the repairing tool to increase the collection of scattered light. [Embodiment] For the detailed structure and working principle of this creation, please refer to the following description: First, please refer to Figure 3, this creation is to provide a lighter for the working surface, to the internal LED crystal The scattered light of the ball 1 acts as a barrier to prevent the emitter from generating unnecessary interference light', and provides a grating 2, which is a plate body 21, and has a light hole 2〇 on the surface, and the periphery of the plate 21 A connecting hole 21〇 is provided, and the optical hole 2〇 is coaxially aligned with the aperture c′ of the LED crystal ball 1 provided by the positive emitter 1 (as shown in FIG. 4). 2〇, the straight 15 of the optical hole 20 may be equal to or slightly smaller than the cross-sectional diameter of the LED crystal ball 1, and it is arranged in a face-to-face manner for the LED crystal ball 丨 working surface arranged by the positive projection light, the aperture 2 〇 Providing the beam of the LED crystal ball ' The above-mentioned working surface is arranged by a plurality of LED sequences, and its surface shape is a plane or a curved surface, or a step shape.
