Grouping detachable light-emitting diode (LED) lamp

Abstract

The invention discloses a grouping detachable LED lamp. The lamp comprises a lamp holder, a driving power supply, welding-free detachable lamp beads and a radiating lamp casing, wherein screw holes are arranged on positive pole fixing feet of lamp beads and negative pole fixing feet of lamp beads, radiating surfaces at bottoms of lamp beads are attached to a radiating inner plate which is connected with the radiating lamp casing, nuts which correspond with positions of screw holes are arranged on the radiating inner plate, positive pole fixing feet of lamp beads and negative pole fixing feet of lamp beads are connected with the radiating inner plate through screws, the driving power supply comprises a plurality of independent subsidiary driving power supplies, and each of the subsidiary driving power supplies is connected with one lamp bead. According to the lamp, traditional LED lamp structures are changed completely, each of the lamp beads is connected with one of the independent subsidiary driving power supplies, so that the discard of the entire LED lamp, which is caused by the damage of a certain part of the driving power supply or the damage of lamp beads, can be avoided, and the usage cost of the LED lamp is reduced; and an aluminum substrate is omitted, so that the heat radiation is direct, the service life of the LED lamp is prolonged, and the energy consumption and the production cost are reduced.

Description

technical field [0001] The invention relates to a grouped detachable LED lamp. Background technique [0002] At present, the existing LED lamps in the domestic and foreign markets are all composed of a driving power supply connected by wires to several small lamp beads connected in series or parallel to each other as an integral structure, and each small lamp bead on the market is made of a lamp. The positive and negative ends of the beads are directly welded on the front of the aluminum substrate, and the back of the aluminum substrate is in contact with the inner plate of the lamp holder (lamp housing) by coating a thermally conductive paste such as silicone grease. This manufacturing process is not only complicated but also has disadvantages: due to the existing The LED lamp bead uses an aluminum substrate as the electrical substrate and the heat dissipation effect is not ideal by coating heat-conducting silicone grease. The LED lamp is easily affected by high temperature...

[0002] At present, the existing LED lamps in the domestic and foreign markets are all composed of a driving power supply connected by wires to several small lamp beads connected in series or parallel to each other as an integral structure, and each small lamp bead on the market is made of a lamp. The positive and negative ends of the beads are directly welded on the front of the aluminum substrate, and the back of the aluminum substrate is in contact with the inner plate of the lamp holder (lamp housing) by coating a thermally conductive paste such as silicone grease. This manufacturing process is not only complicated but also has disadvantages: due to the existing The LED lamp bead uses an aluminum substrate as the electrical substrate and the heat dissipation effect is not ideal by coating heat-conducting silicone grease. The LED lamp is easily affected by high temperature during use and the efficiency is reduced, which not only wastes power but also shortens the service life of the LED. And if it is due to the damage of any small component of the driving power supply or the damage of any lamp bead, the instantaneous voltage and current change will cause other lamp beads to be damaged one after another, making the whole LED lamp unusable and all scrapped.
