Description
Technical field
The utility model belongs to LED automobile lamp technical field, shines in particular to a kind of LED braking Rear Position Lamp
Body.
Background technique
With the gradually decline of the continuous development of LED manufacture technology and maturation and production cost, LED light source has been opened
Beginning is widely used in the fields such as auto lamp, special lighting lamps and lanterns, public illumination, has huge development potentiality, it is considered to be 21
Century light source most with prospects.
As the essential safety component of running car, effect of the automobile lamp in terms of automobile active safety to close weight
It wants.LED is highly reliable, long service life, excitation purity height, fast response time, small in size brings Zhuo convenient for design, to automobile appearance
The advantages that more changing, makes it obtain more and more common application in terms of illumination outside vehicle.Into 21st century, LED car lamp is
Through becoming the new lover of automobile trend, it is widely used on the signal lamps such as turn signal, Brake lamp.In addition in recent years, people couple
The energy-efficient cry of automobile environment-protection is higher and higher, and the advantages of LED energy conservation and environmental protection also results in the extensive concern of people, this is LED
Application on automobile lamp provides great space.
LED automobile lamp Brake lamp on the market and Rear Position Lamp are mostly independently luminous at present, are not associated between the two.
The braking Rear Position Lamp illuminator Rear Position Lamp of LED involved in the utility model is individually lighted when lighting, when Brake lamp is lighted after
Position lamp is lighted simultaneously to increase Brake lamp light-emitting area.
Utility model content
The utility model devises a kind of Rear Position Lamp and lights for the applicable cases of LED braking Rear Position Lamp illuminator
When individually light, when Brake lamp is lighted Rear Position Lamp and meanwhile light with increase the LED of Brake lamp light-emitting area braking Rear Position Lamp
Illuminator.
The technical solution adopted in the utility model is as follows: a kind of LED braking Rear Position Lamp illuminator, including Brake lamp is with after
Position lamp, which is characterized in that the LED braking Rear Position Lamp illuminator Brake lamp and Rear Position Lamp are all made of resistance current limliting
Mode controls respectively LED current used；Added with diode, diode cathode and Brake lamp phase between Brake lamp and Rear Position Lamp
Even, diode cathode is connected with Rear Position Lamp；It is individually lighted when Rear Position Lamp is lighted, Rear Position Lamp same time point when Brake lamp is lighted
It is bright.
The beneficial effects of the utility model are: the mode that Brake lamp and Rear Position Lamp are all made of resistance current limliting controls respective institute
With LED current, Brake lamp and Rear Position Lamp make respective institute by adjusting respectively every paths of LEDs current-limiting resistance size control LED current
Identical with LED current, brightness is consistent, while meeting light distribution light intensity demand.Added with diode between Brake lamp and Rear Position Lamp, two
Pole pipe anode is connected with Brake lamp, and diode cathode is connected with Rear Position Lamp, since diode has unilateral conduction, after guarantee
Brake lamp can not be lighted when position lamp is lighted, and Rear Position Lamp can be lighted simultaneously when Brake lamp is lighted.When Rear Position Lamp is lighted
It individually lights, Rear Position Lamp while being lighted when Brake lamp is lighted, increase Brake lamp light-emitting area, meet light distribution light-emitting area need
It asks.
Detailed description of the invention
Fig. 1 is that the utility model LED brakes Rear Position Lamp luminophor circuit schematic diagram；
Fig. 2 is that the utility model LED brakes Rear Position Lamp illuminator PCB design figure.
Specific embodiment
Specific embodiment of the present utility model is illustrated from circuit and structure with reference to the accompanying drawing.
LED1~LED7 is used the principles of the present invention figure for Brake lamp as shown in Figure 1:, position after LED8~LED19 is supplied
Set lamp use.Resistance R1, R2 and capacitor C1, C2 for filter and when unlatching, shutdown and input voltage float from buffer and make
With.The rectification of diode D1, D2 for circuit play simultaneously as maloperation and caused by positive and negative anodes be reversely connected after protective effect,
Diode D3 is for Brake lamp to be isolated with the circuit of Rear Position Lamp, and anode is connected with Brake lamp, and cathode is connected with Rear Position Lamp,
Due to diode have unilateral conduction, meeting Brake lamp when Rear Position Lamp is lighted can not light, when Brake lamp is lighted after position
Set the requirement that lamp can be lighted simultaneously.Resistance R3, R16 are for controlling Brake lamp LED1, LED2, LED3 electric current；Resistance R4, R11,
R12, R13, R14, R15 are for controlling Brake lamp LED4, LED5, LED6, LED7 electric current；Resistance R5, R6, R7, R8, R9, R10 are used
In control Rear Position Lamp LED8~LED19 electric current.
The PCB design of the utility model is as shown in Fig. 2, wiring board uses surface-mounted device single side fabric swatch, Brake lamp, rear position
LED used in lamp and its control section are all arranged in the front PCB.
