Description

The LED auto lamp

Technical field

The utility model relates to a kind of vapour year lamp.Especially establish and relate to a kind of LED auto lamp.

Background technology

Existing T20 auto lamp generally adopts two kinds of forms, and a kind of is to adopt tengsten lamp; Another kind is to adopt LED lamp (light emitting diode).Adopt the T20 auto lamp of tengsten lamp can not have both positive and negative polarity, universal performance is good, but energy consumption is big, the life-span short.And adopt the T20 auto lamp of LED lamp because the characteristic of diode makes the LED auto lamp that both positive and negative polarity be arranged, cause the universal performance of this LED auto lamp bad.

Therefore, the LED auto lamp that a kind of energy consumption of our demand is little, the life-span is long, universal performance is good.

The utility model content

Based on the deficiencies in the prior art, problem to be solved in the utility model provides the LED auto lamp that a kind of energy consumption is little, the life-span is long, universal performance is good.

The LED auto lamp that the utility model provides comprises lamp housing, by the lamp interface circuit that travels that some LED lamps are formed and are arranged at the lamp body in the described lamp housing, the brake lamp interface circuit that is electrically connected with this lamp body and are electrically connected with described lamp body, the described lamp interface circuit that travels is a bridge rectifier.

As a preferred embodiment of the present utility model, described bridge rectifier is the bridge heap, and this bridge heap volume is little, has saved the space effectively.The output of described bridge heap comprises a positive terminal, is electrically connected with resistance between described positive terminal and the described LED lamp, makes the effect of described bridge heap more outstanding.Described positive terminal place is with heat-shrink tube, in order to prevent short circuit.

As a preferred embodiment of the present utility model, described lamp housing comprises the tail shell, and this tail shell is provided with louvre, has good heat sinking function.The LED lamp of described lamp body is set to multilayer, and every layer is provided with circuit board, and described LED lamp is arranged on this circuit board, and multi-level lamp setting has increased the area coverage of described LED auto lamp, has also strengthened the brightness of lamp.The LED lamp of the ground floor of described lamp body is a round end LED lamp, and this round end LED lamp vertically is installed on the circuit board of described ground floor; Other layers are tack LED lamp, and described tack LED lamp is set in parallel on the circuit board of place.The LED lamp of described lamp body is set to four layers, and the circuit board of ground floor is provided with 19 on round end LED lamp, and other layers are respectively equipped with 6 on tack LED lamp.This set has increased area coverage and luminous intensity better.

Compared with prior art, the beneficial effects of the utility model are by external bridge rectifier, make the lamp interface circuit that travels not have the positive and negative terminal interface, thereby make described LED auto lamp have excellent universality, can adapt to different vehicles.

For making the utility model easier to understand, further set forth LED auto lamp of the present utility model below in conjunction with accompanying drawing.

The specific embodiment

With reference now to accompanying drawing, preferred embodiment of the present utility model is described, with reference to figure 1, the LED auto lamp of present embodiment comprises lamp housing 10, is arranged at the lamp body 20 in this lamp housing 10, the lamp interface circuit 30 that travels that is electrically connected with described lamp body 20, the brake lamp interface circuit 40 that is electrically connected with this lamp body 20.Described lamp housing 10 comprises tail shell 11, and described lamp interface circuit 30 and the brake lamp interface circuit 40 of travelling is arranged at (not shown) in the tail shell 11, and this tail shell 11 is provided with louvre 111, is specially four, in order to heat radiation.Described lamp body 20 comprises circuit board and is installed on some LED lamps on this circuit board, and this LED lamp can divide multilayer to arrange, and can increase the area coverage of light and the intensity that strengthens light like this, and present embodiment is set to four layers.With reference to figure 2, the ground floor LED lamp of described lamp body 20 is a round end LED lamp 21, and quantity is 19, and this round end LED lamp 21 vertically is installed on the first circuit board 23, and is electrically connected with circuit on this first circuit board 23.As Fig. 3, three layers of other of described lamp body 20 are as shown in FIG. second layer LED lamp all, this LED lamp is a tack LED lamp 22, quantity is 6, this tack LED lamp 22 parallel being installed on the second circuit board 24, and be electrically connected with the circuit on this second circuit board 24, the tack LED lamp 22 on other are two-layer is arranged at respectively on tertiary circuit plate 25 and the tertiary circuit plate 26 as the second layer.

With reference to figure 4, the brake lamp interface circuit 40 that is electrically connected with described lamp body 20 comprises two Interface Terminals, is respectively the first brake lamp Interface Terminal 41 and the second brake lamp Interface Terminal 42 simultaneously.The described first brake lamp Interface Terminal 41 forward is connected with an end of described lamp body 20 by first resistance 44, first diode 43 successively; The other end of described lamp body 20 forward is connected with the described second brake lamp Interface Terminal 42 by second diode 45.The described lamp interface circuit that travels specifically comprises the bridge rectifier 30 and second resistance 50, is illustrated in figure 5 as the circuit theory diagrams of described bridge rectifier 30.Bridge rectifier 30 in the present embodiment is specially bridge heap, and integrated circuit not only good stability but also volume is little, saves the space.Described bridge heap comprises two input terminals first lamp Interface Terminal 31 and second lamp Interface Terminal 32 that travels that travels, and two lead-out terminal positive terminals 33 and negative terminal 34.Described first lamp the Interface Terminal 31 and second lamp Interface Terminal 32 that travels that travels is connected with external circuit respectively; Described positive terminal 33 correspondingly is connected with the two ends of described lamp body 20 respectively with negative terminal 34.Described second resistance 50 is arranged between described lamp body 20 and the positive terminal 33.When car in normal driving process, external circuit travels lamp Interface Terminal 32 to described lamp body 20 power supplies by the described first lamp Interface Terminal 31 and second that travels; When car brakes, external circuit is also powered to described lamp body 20 by the first brake lamp Interface Terminal 41 and the second brake lamp Interface Terminal 42, and like this, the electric current in the diode of described lamp body 20 increases, the brightness of described lamp body 20 strengthens rapidly, thus expression brake information.
