Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the main organigram in the vertical section of an embodiment of the present utility model;
Fig. 2 is the part of the circuit theory diagrams of an embodiment of the utility model.
Fig. 3 is another part of the circuit theory diagrams of an embodiment of the utility model.
The specific embodiment
As shown in Figure 1, be the main organigram in the vertical section of a preferred embodiment of the present utility model.Having adopted a kind of insulation crust that can adapt to outdoor severe weather conditions is light fixture outer cover 4, in this light fixture outer cover 4, be provided with one or a few square circuit board 5 (can be other shapes), the light emitting diode 3 of welding some is installed according to certain rules on these circuit board 5; The circuit elements device portions of the promising light emitting diode 3 normal low-voltage dc voltages that show bright and provide also is provided on the circuit board 5, comprise dividing potential drop constant current driving unit (also can be arranged on the decompression filter unit on this circuit board), make the last current stabilization of light emitting diode 3 of passing through about 20 milliamperes.Transformer 7 step-downs are partly adopted in step-down, and this transformer 7 is to be fixed on the light fitting body 1 with card and screw.Circuit board 5 is to be fixed on the special purpose copper post 2 that is positioned at the lamp body body interior or on the features/components of similar copper post by securing members such as screw or bolts.The light emitting diode 3 of some has just constituted light-emitting area by the one side that certain arrangement regulation is installed in circuit board 5.
The arranged distribution that key character is a light emitting diode 3 on the light-emitting area that the utility model relates to, the mode of arranged distribution can be varied, thereby the light manifestation mode of its light fixture is also varied thereupon.The selection of the light emitting diode of monochromatic white light River bank lamp has dual mode: a kind of mode is for adopting white light-emitting diode; Red for adopting, green, the blue three kinds of light emitting diodes of another kind of mode.The mode that adopts three kinds of light emitting diodes of second kind of regular arrangement is being enriched manyly than first kind aspect the light performance, and the white light that the three primary colours colour mixture is come out seems more competitive at aspects such as colour temperature, the soft degree of light.The used light emitting diode of the River bank lamp of colorful conversion is red light emitting diodes, green LED and blue LED, these light emitting diodes drive by the drive circuit that has programmable chip, thus the staggered apparent bright lighting effects of utilizing the colour mixture principle to present colorful conversion.
Having programmable drive circuit in the utility model can design on the circuit board 5 that is mounted with light emitting diode 3, also can design separately on the little circuit board of another piece, utilize parts such as screw or bolt this drive circuit board to be fixed on the locating hole of light fitting body 1 inside, by data wire control signal is transferred to the internal wiring of the circuit board 5 that is mounted with light emitting diode 3 again.
Light fixture outer cover 4 is pressed on the locating slot of light fitting body 1, by screw and painting water-proof adhesive sealing, guarantees that the dustproof and waterproof performance of light fixture can satisfy outdoor abominable instructions for use.One end of copper post 2 is fixed in the suitable positioning screw hole in light fitting body 1 inside, and the other end of copper post 2 is fixing with circuit board 5 by nut, and by certain arrangement mode light emitting diode 3 is installed on the circuit board 5.Transformer 7 is fixed on light fitting body 1 inside by card 6 and screw.External power source enters light fitting body 1 inside by the waterproof bayonet socket of light fitting body 1, connects transformer 7, and the output of transformer 7 is connected on the circuit board 5 by power line.The arrangement mode of light emitting diode 3 on circuit board 5 can be rectangular array, if adopt three kinds of light emitting diodes of red, green, blue to carry out colour mixture, these three kinds of light emitting diodes clocklike are staggered according to a definite sequence so.
Fig. 2 and the circuit theory diagrams that Figure 3 shows that a preferred embodiment of the present utility model, the DC voltage of+15V is to carry out step-down, carry out exporting after rectification (the bridge heap among Fig. 2) and the filtering (the capacitor C2 among Fig. 2) again by transformer unit (J1 among Fig. 2), should+15V voltage provides stable trouble free service voltage and current for through current-limiting resistance each light emitting diode 3 among Fig. 3, and this electric current is about 20 milliamperes.The change that changes the resistance of resistance and take to adapt is by the additive method of the electric current of light emitting diode 3, can change the i.e. optical effect such as the luminous intensity of this light fixture and colour temperature of light emitting diode 3 integral body.Light emitting diode in parallel and series connection according to several a group has as shown in the figure been gone bad one or two light emitting diode, all right operate as normal of other light emitting diode if make.Circuit theory diagrams among Fig. 2 and Fig. 3 are not partly described out driving the circuit theory that the control light emitting diode carries out the lighting effects of colorful conversion, realize colorful conversion lighting effects, can insert programmable chip in the design of the back of step-down filter unit, programme-control by chip makes the circuit that connects different light emitting diodes clocklike disconnect and connects, thereby just manifested versicolor effect by the difference of the three primary colours colour mixture of arranging in pairs or groups.
