Long-service-life LED energy-saving lamp

Abstract

The invention discloses a long-service-life LED energy-saving lamp, and overcomes the defects that existing LED energy-saving lamps are poor in radiating effect, short in service life, large in material consumption, high in manufacturing cost and the like. Radiating passages penetrated from one sides to the other sides are arranged among radiating fins, an integral radiating mechanism is provided with the radiating passages penetrated from one side to the other side, a driving power supply assembly cavity is arranged on the lower portion of a lamp holder assembly, and cavity radiating holes are reserved on the wall of the driving power supply assembly cavity. The long-service-life LED energy-saving lamp as a lighting lamp is good in radiating, long in service life, simple in structure, small in material consumption, convenient to manufacture, low in processing cost and obviously improved in cost performance of LED energy-saving lamps, and compared with the existing LED energy-saving lamps, the long-service-life LED energy-saving lamp has the advantages that inside and outside temperature accumulation is lowered by more than 50%, consumed materials are saved by 30%, comprehensive cost is reduced by 40%, and the service life of the LED energy-saving lamp can be prolonged by more than one third.

Description

technical field [0001] The invention relates to a lighting lamp, in particular to an LED long-life energy-saving lamp. Background technique [0002] LED energy-saving lamps generate a lot of heat when they work, and their working principle makes the heat dissipation problem very prominent. If the heat dissipation is not smooth, it is easy to burn out its drive power (transformation) components, LED chips and other components. [0003] The disadvantage of existing LED energy-saving lamps is that the heat dissipation mechanism connected to the lamp holder and the LED core board has a middle cavity for installing and placing the driving power supply (transformation) assembly, the surrounding wall of the middle cavity is sealed, and the surrounding wall of the airtight middle cavity has several The heat sinks arranged radially, the whole heat dissipation mechanism has no transparent heat dissipation channel (hot air convection channel) from one side to the other side, the air ca...

Problems solved by technology

[0003] The disadvantage of existing LED energy-saving lamps is that the heat dissipation mechanism connected to the lamp holder and the LED core board has a middle cavity for installing and placing the driving power supply (transformation) assembly, the surrounding wall of the middle cavity is sealed, and the surrounding wall of the airtight middle cavity has several The heat sinks arranged radially, the whole heat dissipation mechanism has no transparent heat dissipation channel (hot air convection channel) from one side to the other side, the air cannot be convected horizontally, and the heat dissipation effect is poor. The temperature of the cavity reaches above 80 degrees Celsius, which is easy to burn Damage to its drive power (transformation) components, LED chips and other components shortens the service life and greatly increases the cost of using LED energy-saving lamps. Due to heat dissipation technology problems, the actual service life of LED lamps is generally far less than the theoretical value, and the cost performance is low. Not only that, but this kind of heat dissipation device with a number of radially arranged heat sinks around the airtight cavity has complicated processing technology, many consumables, and high manufacturing cost.
