The technical scheme of the utility model is achieved in that it comprises radiator, PCB circuit board and driving power; Wherein, Said PCB circuit board is installed on the radiator and with driving power and electrically connects; The LED luminescence chip of a plurality of formation matrixes is installed on the PCB circuit board, on the PCB circuit board, be equipped with one with the suitable lens of LED luminescence chip of said matrix, radiator is provided with a power shelf; The two ends of power shelf and said radiator flexibly connect, and said driving power is fixed on the power shelf; Be connected with a corner support on the said power shelf, on the corner support through securing member be connected with one be used for fixing universal projecting lamp fixed muffle.

In the said structure; Said radiator comprises that heat-radiating substrate reaches and the integrated radiating ribs of radiator base plate; Radiating ribs is arranged at the back side of heat-radiating substrate, and said PCB circuit board is installed on the front of heat-radiating substrate, and the last lower limb of said heat-radiating substrate also is provided with radiator frame body.

In the said structure, said fixed muffle comprises the first semicircle sleeve and the second semicircle sleeve, and the said first semicircle sleeve and the second semicircle sleeve are connected to form circular sleeve shape structure through bolt, and the said first semicircle sleeve is connected with the corner support through bolt.

In the said structure, be provided with sealing ring between said PCB circuit board and the lens.

In the said structure, the two ends of said power shelf and said radiator are rotationally connected.

In the said structure, the two ends and the power shelf of said corner support are rotationally connected.

The beneficial effect of the utility model is: one of which, the utility model connect a corner support on power shelf; Can relatively rotate between corner support and the power shelf; And radiator flexibly connects with power shelf, thus, can on the X axle, freely adjust the angle of inclination of radiator; In addition, be rotationally connected through bolt between fixed muffle and the corner support, therefore, the integral body that radiator and power shelf etc. are formed can be on Y direction free angle of inclination; Simultaneously, in use, fixed muffle is sheathed on again on the vertical fixed bar; Whole universal projecting lamp can rotate freely on the Z axle, and by this, the universal projecting lamp of the utility model can be realized the universal adjustment of light projecting direction; And it is simple in structure, and is easy to adjust; Two, radiator is the radiator structure of being made up of substrate and radiating ribs, and its good heat dissipation effect can derive the heat of assembling on the heat-radiating substrate fast, has guaranteed the service life of LED luminescence chip; Three, between said PCB circuit board and lens, be provided with sealing ring, the sealing circle makes projecting lamp have favorable waterproof property, avoids water or dust impurity to get into the serviceability that lens influence projecting lamp.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.

Referring to figs. 1 through shown in Figure 2; The utility model has disclosed a kind of universal projecting lamp, and this universal projecting lamp can be adjusted projecting direction arbitrarily, and it comprises radiator, PCB circuit board 11 and driving power 3; Wherein, Said PCB circuit board 11 is fixedly installed on the radiator through screw and electrically connects with driving power 3, and the LED luminescence chip of a plurality of formation matrixes is installed on the PCB circuit board 11, on PCB circuit board 11, be equipped with one with the suitable lens 8 of LED luminescence chip of said matrix; The edge of lens 8 is provided with through hole; In through hole, be fixedly connected with PCB circuit board 11, be provided with sealing ring 10 between said PCB circuit board 11 and the lens 3, guarantee that internal circuit and LED luminescence chip do not receive external environment influence through screw 9; Radiator is provided with a power shelf 5, and the two ends of power shelf 5 and said radiator flexibly connect, and be preferable, and the two ends of power shelf 5 are rotationally connected through bolt 4 and said radiator both sides, and said driving power 3 is fixed on the power shelf 5; Be connected with a corner support 13 on the said power shelf 5, the two ends of corner support 13 and power shelf 5 are rotationally connected through bolt 4, on the corner support 13 through bolt 2 be connected with one be used for fixing universal projecting lamp fixed muffle.

Radiator comprises that heat-radiating substrate 7 reaches and radiator base plate 7 integrated radiating ribs 6; Radiating ribs 6 is arranged at the back side of heat-radiating substrate 7; Said PCB circuit board 11 is installed on the front of heat-radiating substrate 7, and the last lower limb of said heat-radiating substrate 7 also is provided with radiator frame body 12.Fixed muffle comprises the first semicircle sleeve 14 and the second semicircle sleeve 15, and the said first semicircle sleeve 14 and the second semicircle sleeve 15 are connected to form circular sleeve shape structure through
