Referring to fig. 1 to 2, the arbitrary cutting lamp according to the embodiment of the present invention includes a substrate 100, a plurality of light emitting units 200 and a sleeve 300, where the light emitting units 200 include at most two LED light sources 210 and a voltage stabilizing resistor 220, the LED light sources 210 and the voltage stabilizing resistor 220 are connected in series, and the LED light sources 210 and the voltage stabilizing resistor 220 are disposed on the substrate 100; in the light emitting unit 200 of the embodiment of the present invention, one or two LED light sources 210 may be provided, and a small number of LED light sources 210 are provided in a single light emitting unit 200, so that the area of the single light emitting unit 200 is small, which is convenient for cutting, and on the other hand, the sleeve 300 is sleeved outside the substrate 100 and wraps the light emitting unit 200; wherein, the plurality of light emitting units 200 are connected in parallel.

Two adjacent light-emitting units 200 are connected in parallel, and when cutting is needed, the two light-emitting units 200 are directly cut off, so that the normal operation of a part of the light-emitting units 200 which are connected with the power supply cannot be influenced.

Each light-emitting unit 200 has at most two LED light sources 210, so that the size of the whole light-emitting unit 200 is small, cutting at any position can be realized, and the effect that a large segment of lamp strip cannot be used normally cannot be caused.

It is to be mentioned that the substrate 100 is provided with a wiring; in the single light emitting unit 200, the LED light source 210 and the voltage stabilizing resistor 220 are connected in series through a line. The substrate 100 is processed by a process such as imprinting to form a circuit on the substrate 100, wherein the circuit is designed to be completed from the beginning, and the circuit is a conventional processing means in the art and is not described herein. The LED light source 210 and the voltage stabilizing resistor 220 in the same light emitting unit 200 are connected in series through a processed circuit on the substrate 100.

In any of the cutting lamps according to the embodiments of the present invention, the voltage borne by each of the light emitting units 200 is the same, and the voltage of the common LED light source 210 is too large, so that the voltage stabilizing resistor 220 is connected in series in each of the light emitting units 200, thereby stabilizing the voltage input to the LED light source 210, ensuring the power of the LED light source 210, and avoiding the influence on the life of the LED light source 210 due to heat generation caused by the too large power of the LED light source 210.

In general, the LED light source 210 may be selected to be a patch light bead.

It should be noted that two power lines 400 extending along the length direction of the substrate 100 are disposed on two sides of the substrate 100, and the plurality of light emitting units 200 are connected in parallel between the two power lines 400. The two power lines 400 are connected to a driver (not shown) and to an external power source to directly supply voltage to the LED light source 210.

In the above embodiment, in order to avoid damaging the power cord 400 during use, the sleeve 300 is provided with a mounting groove 310 for disposing the substrate 100, and two sides of the mounting groove 310 are provided with grooves 320 for embedding the power cord 400. The power cord 400 is separately disposed in the groove 320, which can improve the protection effect.

The lamp strip is cut in the manner that the cutting comprises the following two conditions:

1. the cutting position is positioned between two adjacent light-emitting units 200, the lamp strip is directly cut off, so that the two light-emitting units 200 are separated, the light-emitting units 200 on the two sides of the cutting position are kept complete, and the light-emitting units 200 on one part of the lamp strip which is connected with the power supply keep emitting light normally;

2. the cutting position is in the light-emitting unit 200, and the circuit in the light-emitting unit 200 can be cut off during cutting, so that the power supply of the LED light source 210 in the light-emitting unit 200 is lost, and after cutting, the part of the light-emitting unit 200, which is remained on one section of lamp strip connected with the power supply, can not emit light, but because the area of the light-emitting unit 200 is small, the light-emitting unit can be directly ignored, and the whole attractiveness and normal work are not influenced.

It should be mentioned that the sleeve 300 is transparent. The transparent sleeve 300 facilitates the LED light source 210 to emit light and emit into the environment to illuminate the environment.

It should be mentioned that the substrate 100 is a flexible circuit board. Make whole lamp area form the flexible lamp area, in order to cooperate the flexible circuit board, this sleeve pipe 300 generally adopts transparent plastic, and through moulding plastics and process into whole flexible lamp area in the processing.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
