Abstract

The invention provides a PNP pixel lamp convenient to disassemble and maintain. The PNP pixel lamp is characterized in that the PNP pixel lamp comprises a base, a light source module and a locking ring; the base is provided with a cable opening allowing a cable to penetrate, a circuit board connected with the cable is arranged in the cable opening, the base and the circuit board in the base are integrally formed in a sealing manner, and first electrodes making contact with the light source module are exposed outside the base; a light source substrate with LED beads is formed in a full-filling and packaging manner, and second electrodes making contact with the base are exposed outside the bottom face of the light source module; the locking ring is matched with the base to fasten the light source module to the base. According to the PNP pixel lamp, separated independent packaging design and a rotating clamping buckle structure are adopted, field maintenance of an LED light source dot matrix is facilitated, and the maintenance time and the maintenance cost are reduced; and meanwhile, the special multi-sealing waterproof technology is adopted to make up for the defect that the waterproof performance is lowered due to the separation design, so that products have excellent sealing performance and waterproof performance, and the PNP pixel lamp is a product with practicality, technicality and economical efficiency considered.

Description

technical field [0001] The invention belongs to an energy-saving decorative lamp, in particular to a PNP pixel lamp which is convenient for disassembly and maintenance. Background technique [0002] LED point light source is a new type of energy-saving and environmentally friendly decorative lamp. It uses LED cold light source to emit light, with built-in microcomputer chip, which can be programmed and controlled arbitrarily. Effect; multiple LED point light sources can also be formed into a dot matrix screen, which can be controlled by a computer to change various pictures, text and animation effects. It is an ideal decoration for buildings, bridge outlines, billboards, curtain walls and night lighting. [0003] In view of the fact that the use environment of LED point light sources is mostly outdoors, which is seriously affected by rainwater and stagnant water, etc., general LED point light sources will be sealed with glue after assembly, or simply made into a non-detachab...
