It is between 31 and in parallel with an at least LEDs 31 respectively, and each institute of switch module 41 is simultaneously
The quantity of LED 31 of connection is different.Switch module 41 can be respectively by control in a closure
(closed) switch between state and open circuit (open) state, when one of switches set
When part 41 switches to the closure state by control, the driver 5 puts on the illuminating circuit list
The electric current of unit 3 can flow through the switch module 41 in the closure state so that in the closure
All LED 31 that the switch module 41 of state is in parallel are powered off and are stopped lighting.
In the present embodiment, the illuminating circuit unit 3 has been arranged in series six LEDs 31, should
Switch element 4 includes two switch modules 41, and switch module 41 is to be respectively used to be parallel to neighbour
Three LED 31 of the nearly negative pole end 33, and adjacent to five LEDs 31 of the negative pole end 33.
When LED car lamp device of the present invention is implemented, the illuminating circuit unit 3 may be disposed at one
In lamp housing, and single car light is constituted, and the switch element 4 can be integrated in one of vehicle
Car light controller (not shown), can be by operating the car light controller come controlling switch component 41
Switch between the closure state and open-circuit condition, and then may be selected to control the illuminating circuit unit 3
The quantity of LED 31 to be lighted, and the brightness of the relation control car light.
Additionally, when implementing, (figure is not the illuminating circuit unit 3 can be laid in into multiple lamp housings yet
Show) in, to constitute various car lights, for example, it is laid in daytime portable lighter 903, lampet 902 and headlight
In 901 lamp housing, that is to say, that be used for the part LED 31 of the illuminating circuit unit 3
Daytime portable lighter 903, part LED 31 are used for lampet 902, and part LED 31 is used for headlight
901, and the switch element 4 is integrated in the car light controller, it is convenient to be controlled by the car light
Device operation-control switch component 41 switches between the closure state and open-circuit condition, and then selects
The control car light to be opened and closed.
Hereinafter it is laid in multiple lamp housings with the illuminating circuit unit 3, as daytime portable lighter
903rd, lampet 902 is illustrated with the application as a example by headlight 901.
The illuminating circuit unit 3 has been arranged in series six LEDs 31, wherein, the neighbouring positive pole
One LEDs 31 at end 32 are for use as daytime portable lighter 903, and the three of the neighbouring negative pole end 33
LEDs 31 are for use as headlight 901, and remaining two LEDs 31 be for use as it is small

Under normal state, switch module 41 is in the closure state, after vehicle launch, uses
Can be started by the driver 5 in the LED 31 as daytime portable lighter 903 luminous.When needs are opened
When opening lampet 902, the switch module 41 that can will be parallel to five LEDs 31 switches to the open circuit
State, now, for the LED 31 as daytime portable lighter 903, and for as lampet
902 LED 31 can be started luminous by the driver 5.When further starting headlight 901
When, can will be parallel to and switch to this as the switch module 41 of the LED 31 of headlight 901 and open
Line state, now, the electric current that the driver 5 puts on the illuminating circuit unit 3 can flow through institute
There is LED 31, and it is luminous daytime portable lighter 903, lampet 902 and headlight 901 is all started.
Coordinate and refer to Fig. 2, in the above-described embodiments, the illuminating circuit unit 3 has six strings
The LED 31 of connection, the switch element 4 has two switch modules 41, but when implementing, LED
31 with the quantity of switch module 41, and the parallel connection of switch module 41 the quantity of LED 31 not with
The above-mentioned type is limited, and can increase and decrease according to use demand, for example, can also use structure design shown in Fig. 2,
The switch element 4 is provided with five switch modules 41, and switch module 41 is designed into difference
With one, two, three, four it is in parallel with five LED 31.
By above-mentioned design, whole illuminating circuit unit 3 need to only be driven with a driver 5
It is luminous, and because LED 31 is to be arranged in series, so the luminosity of LED 31 can be made uniform, and
It is convenient that the LED 31 to be opened is selected by the switch element 4, and conveniently select to control brightness,
Or the keying of multiple car lights that selection control 3 cloth of the illuminating circuit unit are made to, even
One of LED 31 is damaged, and can also be switched by controlling the switch module 41 connected in parallel
To the mode of the closure state, whole circuit is set to bypass the LED 31 of damage, remaining LED 31
Still can normal luminous, can be greatly reduced and cause whole group car because single LEDs 31 are damaged
The probability that lamp does not work, is a kind of quite convenient and practical LED car lamp device design.
As shown in figure 3, the second embodiment and first embodiment of LED car lamp device of the present invention
It is at difference：The switch element 4 is electrically connected to the structure design of the illuminating circuit unit 3.
For convenience of description, below will be just for being retouched at the present embodiment and the first embodiment difference
State.
