The upper surface of described diffuser is the spherical structure that raises up.
Beneficial effect of the present invention is:
The present invention includes base, be arranged on the light source board of base top, the light source board upper surface is provided with a plurality of led chips, the top of light source board is provided with interior lens mount successively, diffuser, the printing opacity cover cap is located at base top, the upper surface of interior lens mount is convex to be provided with a plurality of interior collector lenses corresponding with led chip, the diffuser inner surface convexes with one or more outer collector lenses downwards, when the light source board operating illumination, the light that led chip sends is through behind the interior collector lens optically focused of interior lens mount, again through the outer collector lens optically focused of diffuser and shine out, the present invention forms two-layer optically focused effect by the interior collector lens of interior lens mount and the outer collector lens of diffuser, illumination effect from light distribution structure aspect control light source, greatly improved the utilization rate of LED light, irradiation distance and the range of exposures of light fixture have been enlarged, be suitable for various abominable conditions of work, can be used for building, view, wait the illumination in place under water, can be as required as Tunnel Lamp, garden lamp, signal lamp, police lamp or mine lamp use.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is cut-away view of the present invention;
Fig. 3 is decomposing schematic representation of the present invention;
Fig. 4 is the structural representation of diffuser of the present invention.
The specific embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing, shown in Fig. 1~4, long-distance spotlight provided by the invention includes base 1, is arranged on the light source board 2 at base 1 top, light source board 2 upper surfaces evenly are provided with a plurality of led chips 3, the top of light source board 2 is provided with interior lens mount 4, diffuser 5 successively, diffuser 5 lids are located at base 1 top, the upper surface of interior lens mount 4 upwards evenly convexes with interior collector lens 41 corresponding to a plurality of and led chip 3, and diffuser 5 inner surfaces convex with one or more outer collector lenses 51 downwards.
Base 1 top offers holding tank 11, and light source board 2 closely is connected to holding tank 11 bottoms, so that the heat of led chip 3 and light source board 2 can in time pass on the base 1, radiator structure is diffused into whole base 1, improves radiating effect.The bottom of base 1 is one-body molded multi-disc fin 12, increased area of dissipation, when led chip 3 operating illumination, the heat that led chip 3 produces reaches on the base 1, fin 12 by base 1 in time promptly distributes, thereby improve the radiating effect of long-distance spotlight, avoid shorten the light decay of the led chip 3 that slows down the service life of led chip 3.
Be hinged with swinging mounting 6 on the base 1, the convenient long-distance spotlight of installing, swinging mounting 6 is rotatable, can make things convenient for adjusting angle.
The middle part of interior lens mount 4 upper surfaces is provided with reflection shield 7, and collector lens 41 is arranged in the reflection shield 7 in one of them, strengthens spotlight effect.The upper surface of interior lens mount 4 is wavy shaped configuration, and the remaining light divergent irradiation of led chip 3 is gone out, and produces closely illuminating effect.
The bottom of interior lens mount 4 is provided with a plurality of joint pins 42, and joint pin 42 bottoms are connected on the base 1, and are easy for installation, and so that interior lens mount 4 keep at intervals with led chip 3.
The upper surface of interior collector lens 41 is spherical, and the lower surface of outer collector lens 51 is spherical, so that light can be assembled better.The optically focused angle of interior collector lens 41 is 3 degree, and the optically focused angle of outer collector lens 51 is 10 degree, improves spotlight effect.
Diffuser 5 inner surfaces convex with the flange collar 52 that is located at interior lens mount 4 outsides, and the medial surface of flange collar 52 is toothed surface.The upper surface of diffuser 5 is the spherical structure that raises up, and improves spotlight effect.The periphery bottom of diffuser 5 offers draw-in groove 53, and the position that base 1 is connected with diffuser 5 is provided with projection 13, and projection 13 is connected in the draw-in groove 53, so that accurate positioning between diffuser 5 and the base 1.
When light source board 2 operating illumination, the light that led chip 3 sends is through behind interior collector lens 41 optically focused of interior lens mount 4, again through outer collector lens 51 optically focused of diffuser 5 and shine out, the present invention forms two-layer optically focused effect by the interior collector lens 41 of interior lens mount 4 and the outer collector lens 51 of diffuser 5, illumination effect from light distribution structure aspect control light source, greatly improved the utilization rate of LED light, irradiation distance and the range of exposures of light fixture have been enlarged, be suitable for various abominable conditions of work, can be used for building, view, wait the illumination in place under water, can be as required as Tunnel Lamp, garden lamp, signal lamp, police lamp or mine lamp use.It is low that long-distance spotlight of the present invention has energy consumption, and the life-span is long, and luminous efficiency is high, uses the characteristics such as safety.
Should be noted that at last; above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although with reference to preferred embodiment the present invention has been done to explain; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement technical scheme of the present invention, and not break away from essence and the scope of technical solution of the present invention.
