Description
Technical field
The utility model relates to a kind of LED line construction, particularly a kind of LED line construction that adopts flexible circuit board.
Background technology
At present, the taillight that uses on the automobile all is to use bulb, use bulb bigger with respect to the brightness ratio of LED lamp, but also there are a lot of weak points in it, though bigger brightness is arranged such as bulb, but can produce very high heat when producing high brightness, long-term work can be quickened the loss of part in the higher environment of heat, directly influences the service life of bulb; Because the service life of this class bulb is shorter, can produce a lot of abandons, causes the pollution of environment and cost very big.Simultaneously, the electric energy of the required consumption of bulb is bigger, greatly is unfavorable for automobile to integrated, the miniaturization development; And characteristics such as that the LED light fixture has is energy-conservation, the life-span is long, almost can cover the life-span of car, and volume is little, and light fitting shape is easy.
Simultaneously, use the steering indicating light circuit all to be arranged on the hard circuit board on the existing automobile, need bigger space when mounted, install also very inconveniently, can't satisfy the vehicle configuration designing requirement.
The utility model content
The purpose of this utility model is to provide a kind of LED line construction that adopts the flex circuit plate, remedies the deficiency of using tail lamp circuit on the existing automobile, adopts flexible circuit board, saves the space of installing, and it is more convenient to install.
The technical problem that the utility model solved can realize by the following technical solutions:
A kind of LED line construction that adopts the flex circuit plate is characterized in that, it comprises a control panel and a LED display board, is electrically connected between described control panel and the described LED display board, and one of described at least control panel and LED display board adopt flexible circuit board to constitute.
Described LED display board is provided with some LED luminescence chips and resistance.
For described LED luminescence chip can firmly be installed on the described LED display board, described LED luminescence chip is fixed on the described LED display board by installing plate.
At least be provided with the led drive circuit that is used to drive described LED display board on the described control panel.
Described control panel is provided with first installing hole of tape welding dish, be provided with second installing hole corresponding to described first installing hole at described LED display board, first installing hole of described control panel firmly is connected by electrically connecting part with second installing hole of described LED display board.
In order to guarantee to keep path between described control panel and the described LED display board, guarantee the reliability of conducting, at the junction scolding tin of described control panel and described LED display board.
A kind of LED line construction that adopts the flex circuit plate of the present utility model adopts flexible circuit board to make control panel and LED display board, reduces control panel and LED display board greatly, very is convenient to simultaneously install, and realizes the purpose of this utility model.
Description of drawings
Fig. 1 is the structural representation of the LED line construction of employing flex circuit plate of the present utility model;
Fig. 2 is the circuit theory diagrams of control panel of the present utility model;
Fig. 3 is the structural representation of LED display board of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment
As shown in Figure 1, a kind of LED line construction that adopts the flex circuit plate, it comprises a control panel 10 and a LED display board 20, is electrically connected between control panel 10 and the LED display board 20, one of control panel 10 and LED display board 20 adopt flexible circuit board to constitute at least.
In the present embodiment, control panel 10 adopts the hard circuit board to constitute, and LED display board 20 adopts flexible circuit board to constitute.
As described in Figure 2, control panel 10 is provided with chip U1 and is the led drive circuit of core and is the clock circuit of core with chip U2.
In control panel 10, be the led drive circuit of core and be that the clock circuit of core is more common circuit with chip U1 with chip U2, just do not given unnecessary details at this.
In the control panel 10, interface P2-1, P2-2, P2-3, P2-4 are connected with automobile BCM controller respectively, and interface P1-1, P1-2 are connected with LED display board 20, send signal by interface P2-1, P2-2, P2-3, P2-4 to chip U1 by the BCM controller; Wherein, the signal of interface P2-1 input is the Brake lamp power supply signal, the signal of interface P2-2 input is the driving lamp power supply signal, the signal of interface P2-3 is the fault feedback signal, when native system breaks down, send signal by interface P2-3 to the BCM controller, interface P2-4 is a ground wire, thus 20 work of driving LED display board.
The clock circuit that with chip U2 is core is for being that the led drive circuit of core provides clock signal with chip U1, in the present embodiment, is that the clock circuit of core is that circuit, DIMMING during for driving lamp take place PWM with chip U2.
As shown in Figure 3, LED display board 20 is provided with LED luminescence chip D1～D14 and resistance R 1, R2, second installing hole 21 that is provided with on the LED display board 20 is used for being connected with control panel 10, certainly, the quantity of LED luminescence chip and resistance and arranged evenly can the adjustment according to the needs of design on the LED display board 20, these do not influence the utility model and realize its purpose.
For described LED luminescence chip can firmly be installed on the LED display board 20, each described LED luminescence chip is fixed on the LED display board 20 by an installing plate 22.(referring to Fig. 1)
More than showing and described basic principle of the present utility model and principal character and advantage of the present utility model. the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
