Summary of the invention

The purpose of this utility model provide a kind of simple in structure, can long-time steady operation, can produce strong visual effect, and the electronic alarm lamp of laying easily.

The utility model comprises face-piece, drain pan, electronic circuit board and battery compartment, electronic circuit board and battery compartment are fixed in the drain pan, it also has leaded light ring, light inlet window and lamp, the leaded light ring is installed between face-piece and the drain pan, light inlet window is installed on the face-piece, and 2 above lamps are installed in the inboard of leaded light ring and the below of light inlet window respectively; Electronic circuit board comprises: pulse oscillation circuit, output pulse triggering signal; Loop counter circuit, carry-out bit selects signal; Lamp drive circuit, it is luminous to drive lamp; Described pulse oscillation circuit output is connected to the trigger end of loop counter circuit, the position of loop counter circuit selects output to be connected with lamp drive circuit more than 2 respectively, when the power supply of input power supply, pulse oscillation circuit work, output triggers frequency to loop counter circuit, make loop counter circuit select signal according to triggering the frequency carry-out bit, connecting different lamp drive circuits, to drive lamp luminous.Telescopic support is equipped with in described drain pan bottom, and magnet is equipped with in the drain pan bottom.Described electronic circuit board also comprises power circuit, power circuit is the DC-to-DC translation circuit, input is battery-powered, press at output output galvanic current by the DC-to-DC conversion, be connected respectively to the power input of pulse oscillation circuit, loop counter circuit and lamp drive circuit.Wherein there is one the lamp that lamp drive circuit drove to be installed on the electronic circuit board of light inlet window below.Described lamp is a light-emitting diode.

The utility model is a light source with the colorful light-emitting diode, with dry cell or small rechargeable pond is power supply, cooperates electronic control circuit to send cyclic flare, flash of light by leaded light ring and light inlet window to around refraction, produce strong visual effect, play effective warning function; Because the utility model is simple in structure, light, have support and magnet, thus can settle easily or be adsorbed on the automobile, also can placement and the place of roadside or field work.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of embodiment of the present utility model;

Fig. 2 is the front schematic view of embodiment;

Fig. 3 is the schematic rear view of embodiment;

Fig. 4 is the electrical schematic diagram of embodiment.

Embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, present embodiment comprises face-piece 1, drain pan 5, electronic circuit board 6, battery compartment 7, leaded light ring 3, light inlet window 2 and lamp 9.Electronic circuit board 6 and battery compartment 7 are fixed in the drain pan 5, and leaded light ring 3 is installed between face-piece 1 and the drain pan 5, and light inlet window 2 is installed on the face-piece 1, and 18 lamps 9 are installed in the inboard of leaded light ring 3, and 10 lamps 9 are installed in the below of light inlet window 2.When lamp 9 was luminous, light can directly penetrate by light inlet window 2, and light can also be by the refraction of leaded light ring 3, by warning lamp disperse ejaculation all around, thereby reach good visual effect, more can quote the attention of dealing people car.

Referring to Fig. 3, telescopic support 8 is equipped with in drain pan 5 bottoms, and magnet 4 is equipped with in drain pan 5 bottoms.After support 8 is pulled out, warning lamp is placed on the object reposefully.Under the state that support 8 is packed up, magnet 4 can make whole warning lamp be adsorbed on very easily on the object of irony, car for example, and plant equipment etc., very convenient in the use.

Referring to Fig. 4, electronic circuit board 6 is made up of power circuit 13, pulse oscillation circuit 10, loop counter circuit 11, lamp drive circuit 12.Power circuit 13 is DC-to-DC translation circuits, present embodiment adopts the booster circuit that MC34063 is connected into DC-to-DC, its input is by the powered battery of battery compartment 7, press at output output galvanic current by the DC-to-DC boosting inverter, be connected respectively to the power input of pulse oscillation circuit 10, loop counter circuit 11 and lamp drive circuit 12.
