Description
Technical field
The utility model belongs to field of illumination lamp technology, is specifically related to a kind of mirror spotlight.
Background technology
LED is widely used as a kind of high efficiency light source in the lighting, and all big enterprises of illuminating industry also design and produced a lot of LED optically focused, Flood lamps and lanterns.When LED uses as the light source of spotlight lamp, in most cases be reflector of a LED coupling.Common LED spotlight structure is that paraboloid combines with the simple of LED, the opening direction of the primary optical axis orientating reflex device of LED.The light of reflector reflects only is to intersect 30 degree or 45 with the LED primary optical axis to spend the light of thinking in the LED concentration structure commonly used; This a part of luminous flux only is 1/3 effect of LED total light flux; The stronger light in center can't obtain utilizing, and causes central light strength low, and spotlight effect is poor.
The utility model content
To the shortcoming of prior art, the purpose of the utility model provides the mirror spotlight that a kind of spotlight effect is good and central light strength is high.
For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of mirror spotlight; It comprises radiator, be located at LED aluminium base on the radiator, be located on the LED aluminium base and a plurality of LED lamps of arranging in the form of a ring, be located at the first oblique reflecting plate on the LED lamp light direction and be located at the second oblique reflecting plate of center in the first oblique reflecting plate; Radiator, LED aluminium base, the first oblique reflecting plate, the second oblique reflecting plate are by a frame fixation; Framework is provided with light-emitting window on the light direction of the second oblique reflecting plate, the LED aluminium base is electrically connected to control circuit.
In this programme, the light of the LED lamp outgoing that annular is arranged can be fully light effectively be focused to outgoing after the light-emitting window central authorities, thereby have improved spotlight effect greatly, and central light strength also can effectively improve after the reflection of twice oblique reflecting plate.
The angle that the first oblique reflecting plate, the second oblique reflecting plate and LED lamp go out optical plane is 40 °-50 °.
The optimum angle that the first oblique reflecting plate, the second oblique reflecting plate and LED lamp go out optical plane is 45 °.
Further, the said second oblique reflecting plate comprises the higher order reflection face, and the stepped structure of higher order reflection face, makes emergent ray can be divided into the spotlight effect of multilayer level.
In order effectively to reduce the loss of light in transmission, said light-emitting window place also is provided with lens.
Further, said framework comprises the interior ring that is used for fixing LED aluminium base, the first oblique reflecting plate, the second oblique reflecting plate, the outer shroud that is used for fixing interior ring and radiator.
Said control circuit is external control circuit structure, the influence that can avoid the heat on the LED aluminium base that control circuit is caused, the service life of effectively improving circuit.
Ring is provided with anti-pull-up structure in said, and the electric connection line of LED aluminium base is connected to external control circuit structure through anti-pull-up structure.
Said outer shroud is through buckle or be tightly fixed on radiator; Said radiator is column structure, and its end is fixed through bonnet.In this programme; Fix radiator through outer shroud and bonnet, do not re-use that existing shell is whole to be coated and fixed, make the most area of radiator directly contact with air; That is to say the direct shell of radiator, improved radiating efficiency greatly as whole lamp.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 mirror spotlight;
Fig. 2 is the structural representation of embodiment 2 mirror spotlights.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is carried out detailed description.
As shown in Figure 1; The utility model discloses a kind of mirror spotlight; It comprises radiator 1, be located at LED aluminium base 2 on the radiator 1, be located on the LED aluminium base 2 and a plurality of LED lamps 3 of arranging in the form of a ring, be located at the first oblique reflecting plate 4 on LED lamp 3 light directions and be located at the second oblique reflecting plate 5 of centers in the first oblique reflecting plate 4; Radiator 1, LED aluminium base 2, first oblique reflecting plate 4, the second oblique reflecting plate 5 are by a frame fixation; Framework is provided with light-emitting window 6 on the light direction of the second oblique reflecting plate 5; LED aluminium base 2 is electrically connected to control circuit, and said light-emitting window 6 places also are provided with lens 7, and said control circuit is external control circuit structure.
The angle that the first oblique reflecting plate, the second oblique reflecting plate and LED lamp go out optical plane is 40 °-50 °.The optimum angle that the first oblique reflecting plate, the second oblique reflecting plate and LED lamp go out optical plane is 45 °.LED lamp wiring level after first oblique reflecting plate 4 reflections is mapped on the second oblique reflecting plate 5, and light vertically penetrates after second oblique reflecting plate 5 reflections again.
Said framework comprises the interior ring 8 that is used for fixing LED aluminium base 2, first oblique reflecting plate 4, the second oblique reflecting plate 5, the outer shroud 9 that is used for fixing interior ring 8 and radiator 1.In order to prevent that the electric connection line on the LED aluminium base 2 is torn easily, said interior ring 8 is provided with anti-pull-up structure 10, and the electric connection line of LED aluminium base 2 is connected to external control circuit structure through anti-pull-up structure 10.Further, said outer shroud 9 is through buckle or be tightly fixed on radiator 1.
Said radiator 1 is column structure, and it is terminal fixing through bonnet 11.
The structural similarity of present embodiment and embodiment 1, its difference are that the said second oblique reflecting plate 5 comprises the higher order reflection face, and the stepped structure of higher order reflection face, makes emergent ray can be divided into the spotlight effect of multilayer level.
