Description

A recharging decoder, car LED lamp recharging decoder and car LED lamp lighting system

technical field

The invention relates to a recharging decoder, a car LED lamp recharging decoder and a car LED lamp lighting system, and belongs to the technical field of car alarms.

Background technique

At present, the original headlights of most automobiles still use halogen tungsten wire H7 lamps as low beam lights. H7 bulbs are the headlight bulb models of GB15766 standard. The problem of short life, now there are various H7 LED rear lights in the aftermarket, and more car owners choose H7 LED rear lights because it has the characteristics of high efficiency and long life.

However, because the car's alarm system will detect the power consumption of the car lights, when the replaced H7 LED rear lights are less than the original car lights H7 halogen lights, then the car's alarm system will always report errors, which will make the driver feel irritable. affect safe driving.

The original headlight H7 halogen lamp = 45W, (in the case of car lamp supply voltage = 13.2V), so the system will detect that the power consumption of the headlight is in the range of 40~50W, and the display will be normal, and the alarm system will not be activated.

However, the power consumption of H7 LED rear lights is about 27W, which is far lower than the 45W of the original lights, so the car's light alarm system will always report errors.

In order to solve the problem of system error reporting, a large number of decoders have appeared in the market, and basically all decoders use one method: resistive decoder. as shown in picture 2.

Since the resistance decoder adopts the method of connecting the resistance to the output terminal of the body controller in parallel, it generates 18W power consumption, plus the 27W power consumption of H7 LED rear lights, which is exactly the same as the 45W of the original lights. As shown in Figure 4. Thereby solving the problem that the car alarm system reports an error. However, since the decoder generates 18W of power consumption, it will affect the heat dissipation of the system, and may burn the mechanism attached to it. If the heat dissipation is not good, it may cause the resistor itself to burn out, and even cause a safety hazard. And practical applications In the case of installing a radiator, the above situation still exists.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

As shown in Figure 5, taking the rear LED lights of a car as an example, a complete lighting system consists of a car battery 1, a body controller 2, a recharge decoder 3, and an H7 LED rear light 4, of which the car battery 1 supplies power To the body controller 2, the voltage = 12V, the body controller 2 has two functions, the first function is the power supply function, responsible for supplying power to the car H7LED low beam, lighting the low beam at night, illuminating the road, convenient and safe driving, power supply voltage = About 13.2V; the second function is power consumption detection and alarm function. When it detects that the power consumption of the low beam function exceeds the set power consumption by 40~50W, it will activate the alarm function and it will not disappear, which will affect the driving mood of the driver. The power consumption of the new H7 LED rear lamp 4 is 27W, which cannot reach the detection setting power consumption of 40~50W. This is due to the combination of light distribution requirements and the current power consumption of LED chips that cannot reach 45W.

The present invention adopts the method that the body controller 2 supplies power to the H7 LED new-style rear mount lamp 4 and simultaneously over-powers the back-flush decoder 3 to solve the car body controller alarm problem, and the battery back-flush decoder 3 adopts the charger principle, specifically Taking a charger circuit shown in Figure 6 as an example (Figure 6 is only one of the circuit structures realized by the present invention, and cannot be used to limit the scope of protection of the present invention), the battery backflush decoder 3 is limited by resistor R6 Input current = 1.4A, and the output voltage is 14~16V controlled by the resistor R13, the power supply current of the body controller 2 = 3.4A, the power supply voltage = 13.2V, reaching a power consumption of 45W, and the power consumption of the new H7LED rear lamp 4 =27W, power supply current=2A, and the remaining 1.4A current is charged back to the car battery 1 through the battery backcharge decoder 3. In this way, the problem of the alarm of the body controller can be solved and the decoding effect can be achieved. And the biggest advantage of using this decoding method is that while the power consumption of recharging is well controlled, the power consumption of the decoder itself is very low, which can optimize the heat of the system and ensure that the temperature inside the lamp cavity will not be too high, and Attached to the plastic shell structure, will not cause overheating of plastic parts, safe and reliable. And through the way of recharging, it can play a real role in energy saving.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should also be regarded as the protection scope of the present invention.
