Regeneration type LED bulb lamp

Abstract

The invention discloses a regeneration type LED bulb lamp. The LED bulb lamp can be replaced only through a screw driver and is composed of a light emitting lamp board, a direct current power source, a lamp holder, a radiator and a lampshade. The radiator looks like a big-end-down inversed cup. Internal threads are formed on the inner circle of the large end to be matched with external threads in a port of the hemispherical lampshade, an annular end face is arranged on the upper portion of the internal threads at the large end of the radiator, and an inner hole in the annular end face just allows the direct current power source to penetrate. The light emitting lamp board is fixed to the annular end face, and heat of the light emitting lamp board is transferred to the whole radiator to be radiated through the annular end face tightly attached to the light emitting lamp board. The lamp holder is in circuit connection with the input end of the direct current power source through a quick-change connector, and the quick-change connector can be led out of the annular end face. The output end of the direct current power source is provided with two pin type plugs sleeved with insulation tubes with positive electrode and negative electrode identifications, and the two pin type plugs penetrate through a via hole in the light emitting lamp board to be in circuit connection with lockable pin type jacks, with positive electrode and negative electrode identifications, in the light emitting lamp board. A direct current power source detection circuit on the light emitting lamp board can detect whether the direct current power source breaks down or not.

Description

technical field [0001] The invention relates to an LED lighting lamp, in particular to an LED bulb lamp. Background technique [0002] The remarkable power-saving effect and long life of LED lamps are recognized, but their price is 3-5 times higher than that of energy-saving lamps, which hinders the promotion of LED lamps. It is urgent to reduce the production cost of LED lamps technically. LED bulb lamps are the most widely used lamp type. The LED bulb lamps in the prior art are interchangeable, but due to structural and process defects, the disassembly of broken lamps is cumbersome and requires professional tools such as multimeters and electric soldering irons. If you don’t have this kind of condition, please ask someone to repair it. I’m afraid the labor is more expensive than the lamp. Repairing the lamp is not as good as buying a lamp. Trouble!

AI Technical Summary

Problems solved by technology

LED bulb lamps are the most widely used lamp type. The LED bulb lamps in the prior art are interchangeable. However, due to structural and process defects, the disassembly of broken lamps is cumbersome and requires professional tools such as multimeters and electric soldering irons. If you don’t have this kind of condition, please ask someone to repair it. I’m afraid the labor is more expensive than the lamp. Repairing the lamp is not as good as buying a lamp. Trouble! The lamp is broken and I have to throw it away

The light-emitting lamp board and DC power supply of LED bulb lamps are vulnerable parts, but the lamp holder, aluminum radiator, and lampshade are all durable parts, and the cost accounts for half of the LED bulb lamp. It is too wasteful to "throw it away"
