Abstract
The invention relates to the technical field of automobile lamps, in particular to an automobile lamp with a heat dissipation structure. The automobile lamp comprises an injection molding lamp shell, a plurality of luminous bodies arranged in the lamp shell, and a light transmitting panel covering the lamp shell, wherein a circuit board is arranged in the lamp shell; heat transmission plates which are arranged on the circuit board, are electrically connected with circuits on the circuit board and are attached to the circuit board are arranged on the luminous bodies; heat dissipation columns are arranged on the heat transmission plates; heat dissipation through holes running through the lamp shell are formed in the lamp shell; the heat dissipation columns are positioned in the heat dissipation through holes. The automobile lamp can transmit heat generated by the luminous bodies out of the automobile lamp for heat dissipation, so that the influence, which is caused by a fact that the heat generated by the luminous bodies is closed in the lamp shell, on the normal use of the automobile lamp is avoided.
Description
Technical field
The present invention relates to car light technical field, be specifically related to a kind of auto lamp with radiator structure.
Background technology
Auto lamp is assemblied on car body for front or the prompting road in the rear participant of throwing light on, during due to light, a large amount of heats can be produced, illuminator is in lamp housing, heat can not shed, thus the temperature in lamp housing raises, and affects the circuit board of illuminator or installation illuminator, finally may cause the damage of car light.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of auto lamp with radiator structure, the heat that illuminator produces can be delivered to car light outside and dispel the heat by it, and the heat avoiding illuminator to produce is closed in lamp housing, affects the normal use of car light.
Realize technical scheme of the present invention as follows:
Auto lamp, comprise injection moulding lamp housing, be arranged on the multiple illuminators in lamp housing, and covering the light penetrating panel on lamp housing, be provided with circuit board in described lamp housing, above-mentioned illuminator is provided with on circuit boards and is electrically connected with the circuit on circuit board, and the heat transfer plate to fit together with circuit board, heat transfer plate is provided with thermal column, lamp housing offers the thermal vias running through lamp housing, above-mentioned thermal column is in thermal vias.
Further, integrally one-step casting is shaping in order to adopt copper material or aluminum material for described heat transfer plate and thermal column, and be convenient to like this manufacture, processing technology is simple, and production efficiency is high.
Further, be arranged with reflective panel between described lamp housing and light penetrating panel, reflective panel be provided with multiple reflective passage, above-mentioned illuminator is in reflective passage one to one, the light that such illuminator sends is gone out by reflective channel emission, can't disturb other illuminators.
Have employed this programme, the heat that illuminator produces can make the temperature of circuit board raise, and combine in lamp housing, heat on circuit board is delivered in thermal vias by heat transfer plate, thermal column, if need to increase radiating rate, cooling medium can be carried in thermal vias to cool thermal column and heat transfer plate by external equipment; The heat that illuminator produces can be delivered to car light outside and dispel the heat by the present invention, and the heat avoiding illuminator to produce is closed in lamp housing, affects the normal use of car light.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described;
With reference to Fig. 1, auto lamp, comprise injection moulding lamp housing 1, be arranged on the multiple illuminators 2 in lamp housing, and cover the light penetrating panel 3 on lamp housing, circuit board 4 is provided with in lamp housing, above-mentioned illuminator is provided with on circuit boards and is electrically connected with the circuit on circuit board, and with the heat transfer plate 5 that circuit board 4 fits together, heat transfer plate 5 is provided with thermal column 6, lamp housing offers the thermal vias 7 running through lamp housing, and above-mentioned thermal column is in thermal vias.Wherein, integrally one-step casting is shaping in order to adopt copper material or aluminum material for heat transfer plate and thermal column.Be arranged with reflective panel 8 in lamp housing and between light penetrating panel, reflective panel is provided with multiple reflective passage 9, illuminator is in reflective passage one to one.
Upper embodiment is not limitation of the present invention, and the scope of protection of the invention includes but not limited to above embodiment, and any improvement carried out on basis of the present invention all belongs to the scope of protection of the invention.
