CN202413598U - Automatic flash electronic bulb - Google Patents

Abstract

The utility model discloses an electronic bulb capable of automatically generating flash signals. A plurality of light-emitting diodes with extremely high brightness are connected in series with one another to form an electronic bulb, and a self-oscillation switching circuit in the tail of the electronic bulb is arranged to drive the electronic bulb to flash so as to form the automatic flash electronic bulb. The automatic flash electronic bulb is mainly used for the steering flash indication of various motor vehicles and can also be used for the signal indication of rear lamps and brake lamps of the motor vehicles, so that the aim of safe driving is fulfilled.

Description

Automatically the electronics bulb glistens

Technical field

The utility model relates to a kind of signal lamp of motor turning flash of light indication, especially can produce the electronics bulb of flashing signal automatically.

Background technology

At present, known automobile-use turning indicator bubble is by glass lamp housing, and filament and lamp tail electrode are formed.To bulb logical go up vdc, light filament, bulb is luminous.But this bulb can not oneself produce flashing signal, must use Der Blink und Abblendschalter to make it produce flashing signal.And be easy to the disintegration of filament, service life is short, and power consumption is big, and not anti-collision is broken easily.If run into drizzle and thick fog, brightness will reduce, and has influenced the safety of driving.

Summary of the invention

The purpose of the utility model provides a kind ofly forms one not with the electronics bulb of filament by several superhigh brightness LEDs.It is long service life not only, and brightness is high, low in energy consumption, anti-collision.When being used for the motor turning indication, can glisten automatically after the energising, form blinker turn signal.Save the Der Blink und Abblendschalter (Der Blink und Abblendschalter also is a consumable accessory) of motor turning indication usefulness, reduced cost, practiced thrift fund, reduced fault rate, guaranteed the safety of driving better.

The purpose of the utility model is achieved in that with 18 orange (because steering lamp for motor vehicle send be orange-colored light) superhigh brightness LEDs, is divided into three groups.Every group with 6 light-emitting diodes, form circuit series, and the negative pole of first light-emitting diode is connected to the positive pole of second luminotron, connects with order.These three groups of circuit series parallel connections, form circuit parallel again.The besieged city semi-spherical shape, profile is the same to bulb.The electronics bulb of so just having formed a withstand voltage 12V power consumption 0.4W.Draw both positive and negative polarity, connect the 12V direct supply and get final product normal luminous work, and brightness is high, low in energy consumption (because the operating voltage of every light-emitting diode is 2.2V, working current is 10mA, power 0.022W, 18 light-emitting diodes just have only 0.4W).

Because the working current of light-emitting diode is little, therefore with two low-power transistors and around self-oscillating switch circuit of element composition, can drive the flash of light work of going out of above-mentioned electronics bulb one bright.(have only two aerotrons because the self-maintained circuit element is few; The electric capacity of two low capacities and three resistance are formed), can pack entire circuit fully in the lamp tail of bulb, so just formed an electronics bulb that glistens automatically; Save Der Blink und Abblendschalter, reached the purpose of automatic flash of light.

Owing to adopt technique scheme; So just formed the indication of can not only glistening automatically, and long service life, high brightness (because light-emitting diode sends is monochromatic light, can penetrate drizzle and thick fog); Der Blink und Abblendschalter is out of use for this reason; Save fund, reduced fault rate, guaranteed the safety of driving better.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the schematic circuit diagram of the utility model.

Fig. 2 is the elevation profile constructional drawing of embodiment of electronics bulb of glistening automatically.

The negative pole of the positive pole 10. lamp tails of the lamp tail 9. lamp tails of mouth 8. bulbs of negative pole 7. self-oscillating switch circuit of positive pole 6. self-oscillating switch circuit of negative pole 4. self-oscillating switch circuit 5. self-oscillating switch circuit of the positive pole 3. electronics bulbs of the electronics bulb 2. electronics bulbs that 1. usefulness light-emitting diodes are formed among the figure.

The specific embodiment

R1=10k Ω R2=10K Ω R3=2.2k Ω C1=16V47 μ F C2=16V47 μ FBG1=9013 BG2=9013 LED=superhigh brightness LED in Fig. 1

In instance shown in Figure 2, the positive pole (2) of electronics bulb (1) is connected to the positive pole (5) of self-oscillating switch circuit (4), and the negative pole (3) of electronics bulb (1) is connected to the mouth (7) of self-oscillating switch circuit (4).The positive pole (5) of self-oscillating switch circuit (4) is connected with the lamp tail anodal (9) of the lamp tail (8) of bulb, and the negative pole (6) of self-oscillating switch circuit (4) is connected with the lamp tail negative pole (10) of lamp bulb tail (8).So just formed an electronics bulb of flash of light automatically.

Claims (1)

1. One kind automatically flash of light electronics bulb form by superhigh brightness LED and flasher circuit, it is characterized in that: be composed in series the electronics bulb of a no filament by several superhigh brightness LEDs, again by self-maintained circuit drive electronics bulb flash of light work.
