Abstract
The utility model discloses a polarization LED support which comprises an anode pin and a cathode pin. An inner reflector is arranged on the upper portion of the cathode pin and is bowl-shaped, and the diameter of a bowl opening of the inner reflector is larger than that of a bowl bottom of the inner reflector. The polarization LED support is characterized in that the surface of the bowl opening of the inner reflector is an oblique plane relative to the bowl bottom, a relatively low end of the bowl opening is close to the anode pin, and a relatively high end of the bowl opening is far away from the anode pin. The inner reflector of the LED support is bowl-shaped, the surface of the bowl opening of the inner reflector is the oblique plane, the inner reflector is asymmetrical, accordingly, an emergent direction of emergent light can be changed to realize a certain polarization effect by the inner reflector with the special structure, a polarization design for a packaged lens is facilitated, and polarization lamp beads meeting requirements of different illumination places can be produced.
Description
Technical field
The utility model relates to the LED technical field, especially a kind of polarized light type LED support and polarisation LED lamp pearl.
Background technology
LED uses more and more extensive, the LED light fixture is also favored by people gradually, the design of led support is the important step that improves the light utilization efficiency of LED lamp pearl, and unique supporting structure can make LED lamp pearl have unique optical effect, thereby makes its application at some lighting field have more advantage.Simultaneously, the utilization rate of raising light also means the reduction of energy consumption.
The led support structure has certain influence to luminous intensity and lighting angle.For example the patent No. is that " 201120060407.5 ", patent name disclose a kind of led support for the Chinese utility model patent of " led support ", comprise anode pin, negative electrode pin, negative electrode pin top is fixed with inner reflector, inner reflector is tapered, the diameter of the diameter of inner reflector rim of a cup at the bottom of greater than the inner reflector cup; The utility model adopts the inner reflector of truncated conical shape.The luminous flux when although this structure can improve LED work, but for some occasion, such as outdoor lighting or road lighting, there is certain defective in the LED lamp of this structure, such as because inner reflector is symmetrical centered by cup-shaped, distribution curve flux is symmetrically distributed and without polarisation, this will cause most of light not shine directly into the effective lighting zone, thereby has reduced the effective rate of utilization of light.Especially in energy-intensive today, needing badly provides a kind of led support that is applicable to the special lighting occasion, so that above-mentioned situation is improved.
The utility model content
The purpose of this utility model provides a kind of led support, can realize polarisation and improve the utilization rate of light with respect to prior art, makes it be adapted to special illumination occasion.
The utility model is realized by the following technical solutions: the polarisation led support, comprise anode pin, negative electrode pin, negative electrode pin top is provided with inner reflector, it is bowl-shape that inner reflector is, the diameter of the diameter of inner reflector the rim of a bowl at the bottom of greater than the inner reflector bowl is characterized in that, a bowl end is an inclined-plane to described inner reflector the rim of a bowl place face relatively, the relatively low end of described the rim of a bowl is near the anode pin, and the relatively high end of the rim of a bowl is away from the anode pin.
Wherein, described negative electrode pin anode pin elongation moulding has protuberance, and inner reflector is fixed in the top of protuberance.
For addressing the above problem, the utility model also discloses a kind of polarisation LED lamp pearl, comprise led support, led chip and package lens, described led chip is packaged on the described led support by package lens, it is characterized in that described led support has the described led support structure of above-mentioned middle any one.
Beneficial effect: because the inner reflector of led support of the present utility model is bowl-shape, the bowl end is an inclined-plane to inner reflector the rim of a bowl place face relatively, inner reflector is asymmetrical shape, so the exit direction of utilizing this special inner reflector structure can change emergent light realizes certain polarisation, and then provide convenience for the design of the polarisation of package lens, meet the required polarized lamp pearls in different illumination places to produce.

The specific embodiment
See also Fig. 1 ~ Fig. 2, polarisation led support 1 of the present utility model, comprise anode pin 10, negative electrode pin 11, negative electrode pin 11 upper punches are pressed with the inner reflector 12 of unsymmetric structure, and inner reflector 12 is bowl-shape, the diameter of the diameter of inner reflector 12 the rims of a bowl at the bottom of greater than bowl, the bowl end is an inclined-plane to inner reflector 12 the rim of a bowl place faces relatively, the relatively low end of the rim of a bowl is near the anode pin, and the relatively high end of the rim of a bowl is away from the anode pin, and chip 2 is fixed at the bottom of 12 bowls of the inner reflectors.The inwall of described inner reflector 12 is cambered surfaces, and described negative electrode pin 11 anode pins 10 elongation mouldings have protuberance 13, and inner reflector 12 is fixed in the top of protuberance 13.
With reference to figure 3, be the utility model polarisation support schematic diagram, be the structure on inclined-plane by inner reflector 12 the rim of a bowl place faces, the light that the led chip 2 of inner reflector 12 bottoms sends is via the reflection of inwall, final so that light is propagated towards roughly the same direction, thereby realizes polarisation, and improves the LED luminous flux, simple in structure, improved the utilization rate of light.
With reference to figure 4, be polarisation LED lamp pearl perspective view.Polarisation LED lamp pearl 3, comprise led support 1, led chip 2 and package lens, utilize package lens led chip 2 to be packaged in the inner reflector bottom of support 1, package lens can be that symmetrical structure also can be unsymmetric structure, wherein, led support 1 comprises anode pin 10, negative electrode pin 11, negative electrode pin 11 upper punches are pressed with the inner reflector 12 of unsymmetric structure, inner reflector 12 is bowl-shape, the diameter of the diameter of inner reflector 12 the rims of a bowl at the bottom of greater than bowl, inner reflector 12 the rim of a bowl place faces relatively a bowl end be an inclined-plane, the relatively low end of the rim of a bowl is near anode, the relatively high end of the rim of a bowl is away from anode, and chip 2 is fixed at the bottom of the inner reflector bowl.As a preferred embodiment, the inwall of described inner reflector 12 is cambered surfaces, and described negative electrode pin 11 anode pins 10 elongation mouldings have protuberance 13, and inner reflector 12 is fixed in the top of protuberance 13.
