Abstract
The utility model belongs to the systems such as braking automobile field, in particular to a kind of brake, more specifically refers to a kind of brake lamp system applied on automobile.Including induction system, the induction system is connected with intelligent controller, and the intelligent controller is connect with LED drive system, and the LED drive system is connected with LED module.For the utility model by setting the size of LED and determining that the number of LED flashing and frequency can be effectively prevented dazzle according to rear car distance, the effect for providing warning is more obvious.
Description
Technical field
The utility model belongs to the systems such as braking automobile field, in particular to a kind of brake, more specifically refers to that one kind is answered
Brake lamp system on automobile.
Background technique
Currently marketed brake form is to step on brake pedal brake lamp to light immediately, i.e. touch brake pedal just lights
Taillight reaches timely warning effect, but display lamp is in permanent bright state always, that is, tramples braking vane, brake lamp can light.
Someone devised a brake lamp with dynamic change again later, and after braking automobile, LED light can show various dynamic images,
The effect of warning rear car driver is mentioned, for example, patent 201020291259.3 just discloses a kind of " locomotive LED tail lamp ",
A kind of locomotive back light in brake can show the LED light of different pattern, make more eye-catching to stop to locomotive during locomotive driving
Vehicle, driving carry out effective prompt
Unquestionably, when running at high speed, the recognition capability of driver is limited, etc. rear cars driver identification, generally come not
And meanwhile, it is easy the energy of dispersion rear car driver when the pattern of the device is more, is easy to increase driving thing instead
Therefore.A kind of patent " automotive high position brake lamp device " CN201320492064.9, discloses a kind of brake lamp of strap brake amount.But
It is that braking amount is big, brightness is high, and human eye will appear dazzle, and when especially the ambient brightness such as evening are small, dazzle is easy to increase and drive
Sail accident.To sum up, the brake lamp which kind of form no matter used at present does not all account for human eye dazzle harm, can not protect rear car
The vision of driver；It does not account for providing warning according to rear car distance, it is therefore necessary to improve existing technology yet.
Summary of the invention
In view of the above problems, the purpose of the utility model is to provide a kind of based on human-eye visual characteristic with warning function
Brake lamp system.
In order to achieve the goal above, the technical solution of the utility model is：
A kind of brake lamp system, the systems such as described brake include induction system, and the induction system is connected with intelligent control
Device, the intelligent controller are connect with LED drive system, and the LED drive system is connected with LED module.
Further, the induction system includes ambient light sensor, rear car range sensor and brake signal line.
Further, the LED module size is 30~35cm.
Further, for the LED module when rear car range-sensor data is 50~100m, flashing times are 3~4
It is secondary, flicker frequency 2Hz；When rear car range-sensor data is 20~50m, flashing times are 3~4 times, and flicker frequency is
5Hz；
According to theories of vision：
LaC2a2=const (1)
La is the brightness of brake lamp, and C is environmental Comparison degree, and a is visual angle.C=La/Lb, Lb are ambient brightness.
Car light size is designed as 30 centimetres, and 200 meters of rear car of design can identify brake lamp, and visual angle obtains 5 points).Const can be taken
=1000, it is obtained by formula (1):
L3a/L2b<400. (2)
According to the theory of lighting glare index UGR, in order not to generate dazzle harm, i.e. dazzle can receive, UGR<16,
La, Lb be respectively brake lamp brightness and environment it is good, w is visual angle, takes 2 points, P is location constant, for vehicle
Lamp takes 1. to obtain:
L2a/Lb<25。 (4)
Combine (2), (4) can obtain：
La/Lb<16 (5)
Brake lamp, La/Lb are identified for clarity>4 (6)
Ambient light sensor measures ambient brightness Lb, according to (5) (6), obtains the range of La.The utility model passes through survey
Examination sets the size of LED and determines that the number of LED flashing and frequency can be effectively prevented dazzle according to rear car distance, mentions
It is more obvious for the effect of warning, there is progress outstanding.
A kind of application of any of the above-described brake lamp system, specifically, the brake lamp system is arranged on automobile,
Ambient light sensor, the setting of rear car range sensor are under automobile tail, the setting of brake signal line and brake pedal bracket
Side.
Detailed description of the invention
Fig. 1 is a kind of circuit structure block diagram of brake lamp system of the utility model.
Specific embodiment
The utility model is described further below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of brake lamp system, the systems such as described brake include induction system, and induction system includes environment
Luminance sensor, rear car range sensor and brake signal line, the induction system are connected with intelligent controller, the intelligence control
Device processed is connect with LED drive system, and the LED drive system is connected with LED module, and LED module size is 30~35cm, by
The LED composition of 10 1W, for the LED module when rear car range-sensor data is 50~100m, flashing times are 3~4
It is secondary, flicker frequency 2Hz；When rear car range-sensor data is 20~50m, flashing times are 3~4 times, and flicker frequency is
5Hz；The brake lamp system is arranged on automobile, ambient light sensor, rear car range sensor are arranged in automobile tail,
The lower section of brake signal line setting and brake pedal bracket.
Above-described embodiment is merely examples for clearly illustrating the present invention, and is not to the utility model
Embodiment restriction.For those of ordinary skill in the art, it can also make on the basis of the above description
Other various forms of variations or variation.There is no necessity and possibility to exhaust all the enbodiments.And these belong to this
The obvious changes or variations that the spirit of utility model is extended out still in the protection scope of the utility model among.
