The specific embodiment
Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be elaborated.
As shown in Figure 2 and Figure 3, the LED warning lamp 20 of first embodiment of the invention includes: one first circuit 21, one end are established one first positive contact 22; One first light emitting diode 23 is serially connected on the first circuit 21; One second circuit 24, one end are established one second positive contact 25, and the other end is connected with the other end of the first circuit 21, and contact is A; One second light emitting diode 26 is serially connected on the second circuit 24; One tertiary circuit 27, one end are established a negative contacts 28, and the other end is connected with the contact A of first and second circuit; One protective resistance 29 is serially connected on tertiary circuit 27; Wherein, the resistance value on the first circuit 21 is greater than the resistance value on the second circuit 24.The present embodiment is to make the driving voltage V1 of the first light emitting diode 23 greater than the driving voltage V2 of the second light emitting diode 26, and namely the resistance of the first light emitting diode 23 is greater than the second light emitting diode 26.
The LED warning lamp 20 of the present embodiment includes in addition: a pedestal 31, make with conducting metal, and be tubular, its bottom is provided with an insulation board 32; One cover body 33 is made with the material of printing opacity or leaded light, is located at the end face of pedestal 31; This first, second and tertiary circuit 21,24,27 all be contained in pedestal 31, wherein first and second positive contact 22,25 is divided on the insulation board 32 of pedestal 31 bottoms, be outer dewiness, negative contacts 28 is connected with pedestal 31, make pedestal 31 form negative contacts that expose, two light emitting diodes 23,26 light-emitting area are all towards cover body 33.The LED warning lamp 20 that makes thus the present embodiment in shape with tungsten filament warning lamp 10 striking resemblances of commonly using, reach compatible purpose.
In use, can use on automobile or the brake taillight of locomotive, when lighting lampet or headlight, the first positive contact 22 energisings, electric current is flowed out by negative contacts 28 through tertiary circuit 27 by the first circuit 21, forms a loop, and this moment, the first light emitting diode 23 was luminous, and the second circuit 24 is not switched on, and therefore the second light emitting diode 26 is failure to actuate.When brake, the second positive contact 25 energisings, electric current is flowed out by negative contacts 28 through tertiary circuit 27 by the second circuit 24, forms another loop, and this moment, the second light emitting diode 26 was luminous.What need be illustrated especially is, protective resistance 29 on tertiary circuit 27 is for the protection of light emitting diode, avoid voltage too large, cause light emitting diode to burn, effect with decompression, for example use the powered battery of a 12V, the driving voltage of the first light emitting diode 23 is 3.6V, the voltage of protective resistance 29 is 8.4V, minimum because of the current sinking of light emitting diode again, protective resistance 29 and the first light emitting diode 23 are connected in series again, and its current value is identical, so protective resistance 29 must select suitable size just can make the circuit normal operation; And the second circuit 24 and the first circuit 21 are to be connected in parallel, during the simultaneously conducting of two circuits when touching on the brake (big light opening and), electric current so far is shunting, driving voltage less (resistance is less) (for example using the light emitting diode of 3.2V) due to the second light emitting diode 26, therefore electric current must flow to the second circuit 24, cause the electric current (voltage) on the first circuit 21 too small, can't drive the first light emitting diode 23 actions, the first circuit 21 is formed open circuit; That is to say when the second light emitting diode 26 when luminous, the first light emitting diode 23 can automatic distinguishings, and this is characteristic of the present invention.Therefore can select the light emitting diode collocation of different colours to use, for example select the light emitting diode that emits white light as the first light emitting diode 23, and select the light emitting diode that glows as the second light emitting diode 26, the white light caution is just arranged when driving lampet or headlight like this, and just there is the ruddiness caution in when brake, and warning function is perfectly clear clearly.
Moreover, the present invention is except using the afterbody brake lamp of vapour, locomotive, also can be used on the steering indicating light of the left and right sides, for example some car type is provided with indicator on the rearview mirror of car both sides recently, if use the present invention, just can form the warning lamp at night on the rearview mirror of both sides, also have simultaneously the effect of indicator concurrently, for example warn when night with white light, turn to indication and work as with gold-tinted, promoted greatly the security of driving.Again, above-mentioned protective resistance 29 also can use bulb as resistor assembly except the resistor assembly of commonly using, or uses (series connection) resistor assembly and bulb simultaneously.
As shown in Figure 4, be the LED warning lamp 40 of second embodiment of the invention, it also includes: one first circuit 41, one end are established one first positive contact 42; One first light emitting diode 43 is serially connected on the first circuit 41; One second circuit 44, one end are established one second positive contact 45, and the other end is connected with the other end of the first circuit 41, and contact is B; One second light emitting diode 46 is serially connected on the second circuit 44; One tertiary circuit 47, one end are established a negative contacts 48, and the other end and first and second circuit 41,44 contact B are connected; One protective resistance 49 is serially connected on tertiary circuit 47; Wherein, the first light emitting diode 43 equates with the driving voltage of the second light emitting diode 46, greater than the second circuit 44, serial connection one small resistor 50 on the first circuit 41, so can reach the effect identical with the first embodiment in addition for the resistance value that makes the first circuit 41.In addition, the bulb 51 of connecting in addition on tertiary circuit 47 utilizes the tungsten filament of bulb 51 to form impedance, if the electric current surging is arranged, forms photo-thermal and dissipates, and the effect of more protection is arranged.
