Description
Technical field
The utility model relates to a kind of hot spot that throws light on and is circular high-brightness LED circular light spot lighting energy saving flashlight, belongs to the LED electricity-saving lamp and makes the field.
Background technology
Granted publication CN 2924279Y, title " a kind of structure of high brightness LED lighting lamp ", this high-brightness LED comprises the knot support of lamp housing, a plurality of high-brightness LED lamp group, illuminating lamp, the number of steps that described LED lamp group is arranged on the described boss structure support of boss structure support respectively is 1～5, and the number of the high-brightness LED of described each high-brightness LED lamp group is 1～100.The structure of described high brightness LED lighting lamp is with the fixing lens of scioptics support respectively on described each high-brightness LED.Its weak point: the one, can't be used to make screw socket lamp, bayonet socket lamp, Down lamp light source and other illuminating lamp; The 2nd, can't produce the rounded hot spot of illumination hot spot, its illumination is that astigmatism irradiation and illuminance are inhomogeneous.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of high-brightness LED circular light spot lighting energy saving flashlight that can either produce the uniform circular illumination hot spot of illuminance.
Design: in order to realize above-mentioned purpose of design.1, led chip is positioned at the design that housing and collector lens are positioned at the below of led chip, is one of feature of the present utility model.The purpose of doing like this is: convex lens are the thicker lens of middle body.Convex lens are divided into biconvex, plano-convex and concavo-convex forms such as (or positive falcates), and thin convex lens have converging action so claim collector lens, thicker convex lens then to look in the distance, disperse or effect such as convergence again, and this thickness with lens is relevant.The utility model is beneficial to the above-mentioned technical characterictic of convex lens just, collector lens is designed to convex lens sheet, and be located at the below of led chip, the light that led chip sends is assembled, make the illumination of led chip be focused on the collector lens and reflex to by collector lens on the minute surface of circular light spot shaping eyeglass, through circular light spot shaping eyeglass, make light be formed uniformly orderly illumination ray.2, circular light spot shaping eyeglass is positioned at the design of collector lens below, is two of feature of the present utility model.The purpose of doing like this is: because circular light spot shaping eyeglass is the convex surface convex lens for plane minute surface, another side simultaneously, the plane minute surface reflects away received light beam by the refraction angle that its lens itself are set by convex lens, form to have the uniform circular light photograph of hot spot.
Technical scheme 1: high-brightness LED circular light spot lighting energy saving flashlight, the input of DC power convertor connects battery by switch, the output termination led chip of DC power convertor, or battery connects led chip by switch, led chip is positioned at housing, collector lens is positioned at the below of led chip, and circular light spot shaping eyeglass is positioned at the below of collector lens.
Technical scheme 2: high-brightness LED circular light spot lighting energy saving flashlight, the input of DC power convertor connects battery by switch, the output termination led chip of DC power convertor, or battery connects led chip by switch, led chip is positioned at housing, collector lens is positioned at the below of led chip, and circular light spot shaping eyeglass is positioned at the below of collector lens, and secondary hot spot shaping eyeglass is positioned at the below of circular light spot shaping eyeglass.
The utility model is compared with background technology, and the one, the logical enough light that high brightness LED chip is produced forms even, the orderly circular light spot of illumination; The 2nd, because led chip is a cold light source, light but not heats can produce heat hardly, can not produce harmful effect to photoenvironment, and energy-saving effect is remarkable; The 3rd, owing to be the space cavity design between led chip in the utility model and collector lens, help the LED thermal resistance and reduce, the light efficiency conversion ratio of LED is improved significantly, improved light efficiency and the power output of LED; The 4th, because led chip is free of contamination solid luminescence source, there is not the pollution to environment in light emitting source itself, is the environmental protection and energy saving products; The 5th, the life-span is long, can reach 100,000 hours in theory.
