Description
Technical field
The utility model relates to a kind of led lamp, especially has the reflection unit that produces the side direction astigmatism.
Background technology
In fashion day by day along with the environmental protection agitation of carbon reduction, led lamp is applied to field of illuminating device widely, and progressively replaces traditional lighting, such as incandescent lamp.For the needs sidelight but not direct radiative specific application area; Such as park Lamp for public place of entertainment or dining table lamp; Because light emitting diode is originally as spot light; Therefore prior art generally need increase extra light distribution device to strengthen sidelight, cooperates the direct irradiation light of lampshade stop portions simultaneously, to satisfy the requirement to sidelight.
Yet; The shortcoming of prior art is that light distribution device has complicated geometrical construction; Use producing required sidelight,, therefore not only increase material such as multilayer shape reflecting surface structure with special reflecting layer; But also need to increase extra manufacturing process, influence the yield of product and the reliability that practical operation is used.Therefore, need a kind of led lamp of tool reflection unit, utilize simply constructed reflection unit, to solve above-mentioned prior art problems.
The utility model content
The main purpose of the utility model is to provide a kind of led lamp of tool reflection unit, comprises substrate, at least one light-emitting diode chip for backlight unit, reflection unit, lampshade, lamp housing and joint, and wherein at least one light-emitting diode chip for backlight unit and reflection unit are placed on the substrate; And reflection unit near or be positioned at the central authorities of substrate; Light-emitting diode chip for backlight unit is evenly distributed on around the reflection unit, lampshade covered substrate, light-emitting diode chip for backlight unit and reflection unit, and the edge of lampshade links the outer rim of substrate; Use the formation enclosure space; Isolated protective effect is provided, and the edge of lampshade further links lamp housing, and lamp housing further links joint.
Reflection unit has the reflecting surface under oblique; Such as single concave surface or plane or a plurality of concave surface or plane with different reflection angles; And the original transmitted light that light-emitting diode chip for backlight unit is launched can form oblique sidelight down after the reflecting surface reflection of reflection unit, and penetrates lampshade.Therefore; But the led lamp mat reflection unit of the utility model provides oblique sidelight down; Do not need to be fit to very much up direct irradiation light and the application of oblique time sidelight of needs only, such as utilizing top barrier to block the park Lamp for public place of entertainment or the indoor situation lamp of direct irradiation light up.
Description of drawings
Fig. 1 shows the sketch map of the led lamp of the utility model tool reflection unit; And
Fig. 2 shows the sketch map of the led lamp of another embodiment tool reflection unit of the utility model.
The specific embodiment
Those skilled in the art below cooperate Figure of description that the embodiment of the utility model is done more detailed explanation, so that can implement after studying this specification carefully according to this.
With reference to figure 1, Fig. 1 is the sketch map of the led lamp of the utility model tool reflection unit.As shown in Figure 1, the led lamp of the utility model comprises substrate 10, at least one light emitting diode (LED) chip 20, reflection unit 30, lampshade 40, lamp housing and joint (wherein lamp housing and joint not are shown among the figure).Led chip 20 and reflection unit 30 are to be placed on the substrate 10, and reflection unit 30 near or be positioned at the central authorities of substrate 10, and led chip 20 is evenly distributed on around the reflection unit 30.
Lampshade 40 tool light transmissions and covered substrate 10, led chip 20 and reflection unit 30, and the outer rim of the edge of lampshade 40 binding substrate 10 are used the formation enclosure space, and isolated protective effect is provided.In addition, the edge of lampshade 40 further links lamp housing, and lamp housing further links joint again, and joint and lampshade 40 be the two relative surfaces sides that are positioned at lamp housing, and its center tap is electrically connected to the led chip 20 on the substrate 10.Therefore, lampshade 40, lamp housing and joint form overall appearance.
Joint connects the external power source (not shown), in order to driving LED chip 20, and produces original transmitted light L1.The surperficial tool reflecting layer of reflection unit 30; In order to reflection ray, and reflection unit 30 has the reflecting surface under oblique, such as the reflective concave surface among the figure; And the original transmitted light L1 that led chip 20 is launched can form oblique sidelight L2 down after the reflecting surface reflection of reflection unit 30, and penetrates lampshade 40.The reflecting surface of reflection unit 30 can further have a plurality of recessed round holes or a plurality of pyramid concave surface, uses and strengthens oblique function of reflecting down.In addition, the reflection unit 30 of Fig. 1 also can have a plurality of reflecting surface (not shown), uses the oblique angular range of sidelight L2 down of flexible adjustment.
In addition; But the top area mat coating reflection layer (not shown) of lampshade 40; And led chip 20 original transmitted light L1 is up reflected downwards, thereby stop original transmitted light L1 up, and have only the oblique penetrable lampshade 40 of sidelight L2 down through reflection unit 30.
With reference to figure 2, Fig. 2 is the sketch map of another embodiment of the utility model.As shown in Figure 2, the led lamp of present embodiment is similar to the embodiment of Fig. 1, and its main discrepancy is that the reflection unit 32 of Fig. 2 has the plane reflecting surface of a plurality of different reflection angles, but not concave surface, remaining component is identical, therefore repeats no more.In addition, each above-mentioned reflecting surface can further have a plurality of recessed round holes or a plurality of pyramid concave surface.
Therefore; The characteristics of the utility model LED light lamp are; Reflection unit capable of using provides oblique sidelight down; Do not need to be fit to very much up direct irradiation light and the application of oblique time sidelight of needs only, such as utilizing top barrier to block park Lamp for public place of entertainment, indoor situation lamp or the lamp decoration of direct irradiation light up.
The above is merely in order to explain the preferred embodiment of the utility model; Be not that attempt is done any pro forma restriction to the utility model according to this; Therefore; All have in following any modification or change of making relevant the utility model of identical creation spirit, all must be included in the category of the utility model intention protection.
