The utility model proposes a kind of light-emitting diode (light emitting diode, LED) lamp bar, LED lamp bar comprises bar shaped support, at least one LED chip and at least one fluorescent glue.Described at least one LED chip is arranged on the side of described bar shaped support.Each fluorescent glue corresponds respectively to a corresponding LED chip to seal the LED chip of described correspondence.Wherein, the minimum point of described fluorescent glue is lower than the side of described bar shaped support.
The utility model also provides a kind of LED lamp bar, and it comprises bar shaped support, multiple LED chip and multiple fluorescent glue.Described multiple LED chip is arranged on the side of described bar shaped support.Each described fluorescent glue respectively a corresponding corresponding LED chip to seal the LED chip of described correspondence.Wherein, the length of the each described LED chip of width coupling of the side of described bar shaped support, and the minimum point of each described fluorescent glue is lower than the side of described bar shaped support.
The beneficial effects of the utility model are that LED lamp bar of the present utility model is arranged on LED chip the side of bar shaped support, and the minimum point of fluorescent glue is lower than the side of bar shaped support, has expanded the lighting angle of LED lamp bar.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technology hand end of the present utility model, and can be implemented according to the content of specification, and for above-mentioned and other objects, features and advantages of the present utility model can be become apparent, below especially exemplified by embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 be the utility model the first embodiment the structural representation of light-emitting diode light bar.
Fig. 2 is the generalized section of the light-emitting diode light bar of the utility model the first embodiment.
Fig. 3 be the utility model the second embodiment the structural representation of light-emitting diode light bar.
Embodiment
Technology hand end and effect of taking for reaching predetermined utility model object for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to embodiment, structure, feature and effect thereof according to the light-emitting diode light bar the utility model proposes, be described in detail as follows:
Fig. 1 is the structural representation of the light-emitting diode light bar 1 of the first embodiment of the present utility model.As shown in Figure 1, light-emitting diode (light emitting diode, LED) lamp bar 1 comprises shown in bar shaped support 10, at least one LED chip 20(figure 4) and at least one fluorescent glue 30(figure shown in 4).
In an execution mode of the present utility model, bar shaped support 10 is strip, and LED chip 20 is cuboid.It will be appreciated by those skilled in the art that, bar shaped support 10 or LED chip 20 can be other shapes such as cylinder.
Wherein, bar shaped support 10 is for example printed circuit board (PCB) of substrate (print circuit board, PCB) of a strip.Bar shaped support 10 comprises upper surface 101, lower surface 102 and side 103.Wherein, side 103 is a plane.At least one LED chip 20 is arranged on the side 103 of bar shaped support 10.Each fluorescent glue 30 corresponds respectively to a corresponding LED chip 20 to seal corresponding LED chip 20, and each fluorescent glue 30 all contacts with upper surface 101 and the lower surface 102 of bar shaped support 10.
In an execution mode of the present utility model, the central point of LED chip 20 is positioned on the symmetry axis of side 103 of bar shaped support 10.The length D of the width H coupling LED chip 20 of the side 103 of bar shaped support 10.Concrete, the width H of the side 103 of bar shaped support 10 is 1～3 times of length D of LED chip 20.
In an execution mode of the present utility model, LED chip 20 is cascaded, thereby forms LED string, luminous to receive driving voltage.
Fig. 2 be light-emitting diode light bar of the present utility model generalized section.As shown in Figure 2, fluorescent glue 30 parcels are positioned at the corresponding LED chip 20 of bar shaped support 10 sides 103, and the minimum point of fluorescent glue 30 is lower than the side 103 of bar shaped support 10, LED chip 20 is when luminous, when getting to the fluorescent material in fluorescent glue 30, light can there is diffuse reflection, part light can penetrate out lower than the position of bar shaped support 10 sides 103 from fluorescent glue 30, thereby makes the lighting angle of LED lamp bar 1 be greater than 180 degree, has expanded the lighting angle of LED lamp bar 1.
In an execution mode of the present utility model, fluorescent glue 30 is hemisphere face shape, certainly it will be appreciated by persons skilled in the art that fluorescent glue 30 also can adopt other shape.
Fig. 3 is the structural representation of the light-emitting diode light bar 2 of the second embodiment of the present utility model.The structure of the light-emitting diode light bar shown in structure and Fig. 1 of light-emitting diode light bar 2 is as shown in Figure 3 roughly the same, and difference is only: the side 103 of bar shaped support 10 ' is serrated face.
