Abstract

The utility model relates to a brake light comprising a casing, a light passing board, an EL device and a connecting socket of the EL device, wherein, the EL device is installed on the connecting socket of the EL device. The light passing board is installed on the EL device and is arranged in the casing. The EL device arranged in the casing, under the control of some device, can send out obviously diacritical display signs of decelerating, braking and hard braking to a back automobile according to the braking strength of an automobile, which provides an accurate judging basis for a back automobile driver. Particularly, when the automobile brakes emergently, the brake light can send out a quickly flickering special light beam in a '!'-shaped to remind the back automobile driver to brake emergently so as to avoid the back automobile from a ' rear-end collision accident'.

Description

Brake light

The utility model stoplight stop lamp belongs to the automobile brake lamp device, especially has the high-mount stop lamp device of indicative symbol.

The circuit of common stoplight stop lamp and common high-mount stop lamp links to each other with brake pedal, and is bright when brake pedal is depressed; The releasing of brake pedal does not promptly work.This mode, stoplight stop lamp has only bright, dark two states can only show whether the driver brakes, and how (as sudden stop, brake, three kinds of states of deceleration) can't show to the brake degree, particularly in the driving at night, the driver can only rely on the car light signal of preceding vehicle to judge.When the front truck sudden stop, back car is thought to slow down and is failed sudden stop, and back car just is easy to knock front truck, the generation rear-end collision.When the front truck deceleration, when back car is thought sudden stop, back car sudden stop, rear-end collision also takes place in the car of back car back most probably.Therefore, deceleration, brake, anxious the stopping of distinguishing in the vehicle traveling process is very important.

The purpose of this invention is to provide the new brake signalling apparatus that a kind of car backward sends obvious distinguishing signal, especially have the brake read out instrument of deceleration, brake, three kinds of unlike signals of sudden stop.

For achieving the above object, the present invention has adopted a kind of new brake lamp that comprises shell, electroluminescent device and electroluminescent device Connection Block.Electroluminescent device is installed on the electroluminescent device Connection Block, and the electroluminescent device Connection Block is installed in the enclosure, electroluminescent device be arranged in profile be exclamation mark "! " caution symbol.The exclamation mark of being arranged "! " caution symbol in, electroluminescent device can also be transversely arranged, composition form be " " caution symbol, or form be " " caution symbol, or "

" caution symbol, or form be "

" caution symbol.Electroluminescent device in the stoplight stop lamp is under certain device control, the luminous symbol different according to the braking strength conversion, as big and strong stimulation danger alarm signal flicker, flicker or do not glimmer and have irritating dangerous tip symbol, Chang Liang has tell-tale prompting symbol.Utilize the different of the shape of these symbols and flicker frequency and distinguish different braking strengths.For example: when automobile is in sudden stop, the light composition that electroluminescent device sends "! " exclamation mark; When automobile is in when brake, the light that electroluminescent device sends for "

" shape, perhaps be "

" shape; When automobile is in when slowing down, the light that electroluminescent device sends for "

" shape or " two " or with "

" shape is luminous or not luminous.Like this vehicle in motion, back car can be understood the braking strength of front truck according to the front truck shown symbol of stoplight stop lamp in the process of moving, takes suitable measure, avoids taking place " rear-end collision ".

The comparatively ideal arrangement mode of above-mentioned electroluminescent device be "

".Utilize this arrangement mode and certain control setup, can make automobile when sudden stop, demonstrate the sudden stop danger alarm signal "! ", brake the time demonstrate noticeable brake cue "

" or "

", when slowing down, demonstrate " two " or "

" or "

" etc. the deceleration cue of form,

For further improving the caution effect of stoplight stop lamp, electroluminescent device is except demonstrating different outer symbols according to braking automobile intensity, can also be according to the difference of braking automobile intensity and with different frequency scintillations, during as sudden stop with higher frequency show exclamation mark "! ", during brake with general frequency demonstrate the water droplet shape "

" or "

", demonstrate two strigulas " two " during deceleration, or with "

" luminous demonstration, or with "

" luminous demonstration.

Certainly when sudden stop, brake and deceleration, the symbol that electroluminescent device was combined into not necessarily is confined within above-mentioned several examples of having described, also can be under this thinking and method, concrete spread pattern has certain variation, the utility model electroluminescent device, can be light-emitting diode, can be bulb or fluorescent lamp.

Above-mentioned solution, make automobile in " sudden stop-brake-deceleration " three kinds of braking states, stoplight stop lamp sends shape and the visibly different alarm signal of frequency respectively, make the back car can understand the braking strength of front truck in motion immediately according to the shown symbol of stoplight stop lamp in the front truck driving process, take suitable measure, avoid taking place rear-end collision.
