Description

A kind of LED particle arragement construction of polychrome heavy wall light guide

Technical field

The utility model relates to automobile lamp technical field, in particular to the LED particle of a kind of polychrome heavy wall light guide is arranged Structure.

Background technique

LED in the car using more and more extensive, especially on lamps and lanterns, LED particle color abundant and small Volume makes automobile appearance increasingly have modern sense.A kind of conventional design LED particle arragement construction as depicted in figs. 1 and 2 In, the second LED particle 202' is one in the second reflector 301' and the second LED module 201' on the second heavy wall light guide 300' One is corresponding, so in use, because the second reflector and the second LED particle correspond, when the second LED particle is lighted only It is photochromic that one kind can be issued, cause heavy wall light guide item that can only realize simple function, to realize two kinds of functions of turn signal and back-up lamp, It just needs to match using the second pcb board 200' of two second heavy wall light guide items and large area and just be able to achieve, consider further that and dissipate Heat problem allows for lamp interior and needs very big installation space, so just makes the own wt of lamps and lanterns and volume all can be very Greatly, lamps and lanterns are in turn resulted in very high manufacturing cost.

Therefore, the LED particle arragement construction in existing automobile lamp, exist have a single function, volume is larger and manufacture The problem of higher cost.

Utility model content

The utility model is asked to solve above-mentioned technology present in the LED particle arragement construction in existing automobile lamp Topic, provides a kind of LED particle arragement construction of polychrome heavy wall light guide, it has feature-rich, small volume and the manufacturing The characteristics of cost is relatively low.

The technical solution of the utility model includes: a kind of LED particle arragement construction of polychrome heavy wall light guide, including lamp housing, setting Pcb board in lamp housing and the heavy wall light guide item being arranged in lamp housing, the pcb board is equipped with several LED modules, the LED Mould group is made of a LED particle and a LED particle with back-up lamp function with turn signal function, the heavy wall light Conducting bar is equipped with several reflectors, and the reflector and LED module are to correspond, the center of the reflector with have The center of the LED particle of back-up lamp function is corresponding.The utility model is by the way that reflector and LED module to be established as one by one LED module is designed as LED particle by one with turn signal function and one with back-up lamp function by corresponding structure The structure of LED particle composition, the LED particle of corresponding two different function in each reflector, so that needing heavy wall light guide originally The effect that item and greater area of pcb board are just able to achieve passes through a heavy wall light guide item and can be real compared with the pcb board of small area It is existing, while having the characteristics that feature-rich, space and the cost of lamps and lanterns is also greatly saved, ensure that the lesser body of lamps and lanterns Product, also provides more design spaces for other shape-designings of lamps and lanterns；The utility model fully takes into account back-up lamp function It is larger to light distribution intensity requirement, so by the center of the center of reflector and the LED particle with back-up lamp function Corresponding setting guarantees that its luminous energy is used effectively, it is contemplated that turn signal is smaller to luminous flux requirement, even if placing it in reflective The slightly inclined position of bowl is also able to satisfy the requirement with luminous intensity, so set the LED particle with turn signal function to slightly partially Center from reflector, the entire LED particle with back-up lamp function, the LED particle with turn signal function and reflector it Between position corresponding relationship it is ingenious in design, reasonable.

Preferably, the LED particle with turn signal function is sodium yellow LED particle, it is described that there is back-up lamp function The LED particle of energy is white light LED particle.Different function corresponds to the LED particle of different colours, is to meet automotive field Industry requirement achievees the purpose that convenient for personal identification.

Preferably, the LED particle with turn signal function in the LED module and LED with back-up lamp function Spacing between grain is 0.3~1mm.The design of spacing is while guaranteeing that good light function is realized, so that production technology can Row.

Preferably, the LED particle with turn signal function in the LED module and LED with back-up lamp function Spacing between grain is 0.5mm.

The utility model has the following beneficial effects:

By the way that reflector and LED module are established as one-to-one structure, LED module is designed as being had by one turns There is the structure of the LED particle composition of back-up lamp function to the LED particle of lamp function and one, correspond to two in each reflector The LED particle of different function, so that the effect for needing heavy wall light guide item and greater area of pcb board to be just able to achieve originally passes through one It root heavy wall light guide item and can realize compared with the pcb board of small area, while having the characteristics that feature-rich, also greatly save The space of lamps and lanterns and cost, ensure that the lesser volume of lamps and lanterns, also provide for other shape-designings of lamps and lanterns and more set Count space；It is larger to light distribution intensity requirement to fully take into account back-up lamp function, so by the center of reflector and have The corresponding setting in the center of the LED particle of car light function guarantees that its luminous energy is used effectively, it is contemplated that turn signal is logical to light Amount requires smaller, is able to satisfy the requirement with luminous intensity placing it in reflector slightly inclined position, so will have steering The LED particle of lamp function is set as being offset slightly from the center of reflector, entirely LED particle with back-up lamp function, have turn It is ingenious in design, reasonable to the position corresponding relationship between the LED particle and reflector of lamp function.
