In the figure: 1. the lamp comprises a shell, 101, a substrate, 102, packaging adhesive, 2, a lamp strip, 3, a lamp bead, 4, a bridge pile, 5 and a power line.

The objects, features and advantages of the present invention will be further described with reference to the accompanying drawings.

Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-4, an embodiment of the present invention is provided, which is a non-polar light strip, including a closed housing 1, the housing 1 includes a substrate 101 with a groove formed on a surface thereof, the substrate 101 may be an aluminum profile, the substrate 101 is provided with an encapsulation adhesive 102 for sealing the opening surface of the groove, and a cavity is formed on the surface of the substrate 101.

The inner cavity of the shell 1 is provided with a lamp strip 2, the lamp strip 2 is located in a cavity formed by the packaging adhesive 102 and the substrate 101, the light emitting surface of the lamp strip 2 faces the packaging adhesive 102, the packaging adhesive 2 is made of a light-permeable material, and light emitted by the lamp beads 3 can be transmitted out. The lamp strip 2 comprises a plurality of lamp beads 3, the lamp beads 3 are connected to form a passage, and the lamp beads 3 in the lamp strip 2 can be connected in series in sequence, can also be connected in parallel with each other, and can also be connected in series and in parallel for sharing.

One end of the inner cavity of the shell 1 is provided with a bridge rectifier 4, the model of the bridge rectifier 4 is MB10F, the bridge rectifier has the function of converting alternating current with the level floating up and down at the zero point into unidirectional direct current through the unidirectional conduction characteristic of the diode, and the function is rectification. The positive pole of 4 output ends of bridge rectifier is connected with the positive pole electricity of lamp strip 2, and the negative pole of 4 output ends of bridge rectifier is connected with the negative pole electricity of lamp strip 2.

The inner cavity of the shell 1 is provided with two power lines 5 which are insulated from each other, and the two power lines 5 are insulated from the shell 1. Two wiring contacts at the input end of the bridge rectifier 4 are respectively and electrically connected with a power line 5.
