Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of constant-voltage light bars, in particular to a constant-voltage light bar that is easy to cut. Background Art
[0002] Constant voltage light strip is a kind of LED lighting product, which works by constant voltage power supply. As a semiconductor light-emitting device, LED (Light Emitting Diode) needs appropriate current and voltage to drive. The traditional constant current drive method uses current to drive LED lighting products, that is, the current size is controlled according to the current characteristics of the LED to achieve stable light emission. The traditional constant voltage light strip has the following problems:
[0003] 1. The light strips need to be cut in groups of three. In practical applications, the size of the light strips should be fixed, resulting in high losses and low energy conversion, which cannot achieve the effect of energy saving and consumption reduction.
[0004] 2. The resistor must not only reduce the voltage but also limit the current, so a larger resistance value should be selected. As a result, there will be a lot of energy loss and poor conversion effect, which cannot achieve the effect of energy saving and consumption reduction.
[0005] In order to solve the above technical problems, a constant voltage light strip that is easy to cut is proposed. Utility Model Content
[0006] 1. Technical issues to be resolved
[0007] In view of the shortcomings of the prior art, the utility model provides a constant voltage light strip that is easy to cut, which solves the technical problem that traditional constant voltage light strips need to be cut in groups of three, and in actual applications they must be cut to fixed sizes, resulting in high losses, low energy conversion, and failure to achieve the effect of energy saving and consumption reduction.
[0008] (II) Technical solution
[0009] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:
[0010] A constant voltage light bar which is easy to cut comprises a light emitting diode and a voltage-dropping and current-limiting resistor, wherein four light emitting diodes and one voltage-dropping and current-limiting resistor form a light emitting unit group.
[0011] Preferably: compensation circuits are added to both the head and tail of the electronic circuit of the constant voltage light strip.
[0012] Preferably: four light emitting diodes form a multi-point parallel circuit, and the number of light emitting unit groups composed of light emitting diodes and step-down current limiting resistors is unlimited.
[0013] (III) Beneficial effects
[0014] 1. Four light-emitting diodes and a step-down current-limiting resistor form a light-emitting unit group, which can work normally as a single group after cutting. Compensation circuits are added to the head and tail of the constant-voltage light strip electronic circuit. Four light-emitting diodes form a multi-point parallel circuit. After one light-emitting diode is cut off, another diode can be used for circuit compensation. Therefore, other light-emitting diodes will not be affected by one light-emitting diode being cut off. There is no limit to the number of light-emitting unit groups composed of light-emitting diodes and step-down current-limiting resistors.
[0015] 2. The step-down current-limiting resistor mainly plays the role of current limiting in the circuit, so the energy loss is small. When one of the light-emitting diodes is cut, the other light-emitting diodes can also use the compensation circuit to emit light normally to prevent a single light-emitting diode from not emitting light normally. In practical applications, it can greatly reduce the waste of materials, better save energy, and improve work efficiency, thereby achieving the effects of energy saving, environmental protection, and consumption reduction.

[0020] Example
[0021] The overall idea of the technical solution in the embodiment of the present application is as follows:
[0022] In view of the problems existing in the prior art, the utility model provides a constant voltage light bar that is easy to cut, including a light emitting diode 1 and a step-down current limiting resistor 2, wherein four light emitting diodes 1 and one step-down current limiting resistor 2 form a light emitting unit group, which can work normally as a single group after cutting, and a compensation circuit 3 is added to the head and tail of the electronic circuit of the constant voltage light bar, and the four light emitting diodes 1 form a multi-point parallel circuit. After one light emitting diode 1 is cut off, the circuit can be compensated by another diode, so that the other light emitting diodes 1 will not be affected by the cutting of one light emitting diode 1, and the number of light emitting unit groups composed of the light emitting diode 1 and the step-down current limiting resistor 2 is unlimited;
[0023] The step-down current-limiting resistor 2 mainly plays a current-limiting role in the circuit, so the energy loss is relatively small.
[0024] Working principle: when one of the light-emitting diodes 1 is cut, the other light-emitting diodes 1 can also use the compensation circuit to emit light normally to prevent a single light-emitting diode 1 from not emitting light normally. In practical applications, it can greatly reduce the waste of materials, better save energy, and improve work efficiency, thereby achieving the effects of energy saving, environmental protection, and consumption reduction.
