Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.It should be noted that, if do not conflicted, each feature in the utility model embodiment and embodiment can be combined with each other, all within protection domain of the present utility model.
Embodiment 1
Refer to Fig. 1, Fig. 1 is the structural representation of the LED photovoltaic module of the LED lamp of the utility model preferred embodiment.As shown in Figure 1, the LED photovoltaic module 1 of the utility model preferred embodiment comprises: circular substrate 2, be located at LED drive circuit and the plurality of LEDs lamp 3A on described circular substrate 2 surface, 3B, 3C, 3D, wherein, described circular substrate 2 surface is provided with multiple concentric annular regions, in each described concentric annular regions, some described LED distribute with preset space length circular array, the center of circle of described multiple concentric annular regions overlaps with the center of circle (namely circular substrate is provided with the central point on the surface of LED drive circuit and LED) of described circular substrate, the described LED 3A of described multiple donut, 3B, 3C, 3D is linearly arranged on the diameter line through the described center of circle in the same direction.For example, as in Fig. 1, the LED linearly proper alignment of distribution separately on diameter line MN and AB, six LED lamp on same diameter line MN or AB are distributed on three donuts varied in size, each donut comprises two LED lamp, and the center of circle about place donut is symmetrical.And all LED circular array distributions be positioned on same donut.
The LED of LED photovoltaic module of the present utility model is distributed on circular substrate has arrangement as elucidated before, and structure is simple not to the utmost, and through experimental verification even light mixing, heat radiation is good.
In a specific embodiment, the center of described circular substrate 2 is provided with power line through hole 7, and described LED drive circuit comprises at least two LED drive chip 4,8, described at least two LED drive chip 4,8 points be clipped to described power line lead to 7 distance equal.
In a specific embodiment, on described circular substrate surface orthogonal two to be provided with the described LED quantity that the described diameter line of described LED distributes identical.Such as, the quantity of the LED quantity of distribution on diameter line MN and the upper LED distributed of diameter line AB is all six, and the diameter line on the clockwise 45 degree of directions of diameter line MN is provided with 4 LED lamp, and the diameter line on the clockwise 45 degree of directions of diameter line AB is also provided with 4 LED lamp, the diameter line that the diameter line also namely on the clockwise 45 degree of directions of this diameter line MN is vertical is provided with 4 LED lamp equally.
