One optical element, this optical element be incorporated into LED wafer above.

The edge of described Lamp cup groove is provided with second electrode that is used to introduce first electrode of power supply and is used to draw power supply.

In the great power LED lamp of described two same structures, first electrode of a light fixture cooperates with second electrode of second light fixture to be realized being electrically connected.

In the described light emitting diode module, a plurality of LED wafers are electrically connected in series, and are provided with lighting of high voltage and constant current IC these a plurality of light-emitting diode chip for backlight unit of chip drives.

In the described light emitting diode module, a plurality of LED wafers are divided into two groups, first group and second group of wafer are electrically connected in series respectively, two groups of wafers after the series connection are in parallel to be electrically connected, and is provided with two high voltage and constant current IC chips and drives lighting of first group and second group wafer being electrically connected in series respectively.

Described optical element is funnelform reflector, this reflector be arranged on LED wafer above, and have first opening and second opening, first opening combines with the Lamp cup groove, second opening is big away from Lamp cup groove and relative aperture first opening.

Described optical element is a collector lens.

Described optical element is a fluorescent glue.

Described optical element is any two kinds combination among reflector, collector lens and the fluorescent glue three.

The utility model compared with prior art its beneficial effect is: owing to adopt light emitting diode module as light emitting source, wherein said light emitting diode module is to be arranged in a combination according to certain order by a plurality of LED wafers, and on LED wafer, be provided with the optical element of concentrating light, thereby make emergent ray intensity height, the directionality that light penetrates is stronger, and more concentrated; Because described a plurality of LED wafers all are powerful wafers, after combining, be easy to obtain the led lamp or the module light fixture of high-power (surpassing 50W) again, and make simple, easy to use, practicality is stronger.

The specific embodiment

Is the function and benefit of further understanding architectural feature of the present utility model in depth and can reach, now enumerates specific embodiment, and detailed introduction of conjunction with figs. is described as follows:

Great power LED lamp as shown in Figure 1, comprises the metal substrate of being made by aluminium (Al) or aluminium (Al) alloy 10, and this substrate 10 is formed with at least one Lamp cup groove 101, is formed with the boss 101a of a plurality of arrangements in its Lamp cup groove 101; Light emitting diode module comprises a plurality of LED wafer 101b, and is placed on the boss 101a corresponding in the Lamp cup groove 101; And the edge of Lamp cup groove 101 is provided with second electrode 104 that is used to introduce first electrode 103 of power supply and is used to draw power supply.And on its LED wafer 101b in conjunction with an optical element, this optical element can be fluorescent glue, reflector, collector lens and other optical element that can reach same effect.

With reference to Fig. 2, this figure is the cutaway view at A-A place among Fig. 1.As can be seen from Figure, be provided with fluorescent glue 101c above the described LED wafer 101b, this fluorescent glue 101c covers whole Lamp cup groove 101, and a little more than substrate 10.
