Low-cost high-efficient radiating device of long-service-life LED energy-saving lamp

Abstract

The invention discloses a low-cost high-efficient radiating device of 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, complex in processing technology, large in material consumption, high in manufacturing cost and the like. At least three radiating fins are arranged between a lamp holder connecting mechanism and a core board connecting mechanism, a radiating passage penetrated from one side to the other side is reserved between every two radiating fins, an integral radiating mechanism is provided with the radiating passages penetrated from one side to the other side, end portions of the radiating fins are mutually connected to form an integral end face, and LED chips are mounted on the integral end face. The low-cost high-efficient radiating device as the radiating device of an LED lighting lamp is good in radiating, 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, 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 a low-cost and high-efficiency heat dissipation device for 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 the driving power supply (transformer) assembly, the surrounding wall of the middle cavity is sealed, and the surrounding wall of the airtight middle cavity has several shapes. The heat sinks arranged radially, the whole heat sink has no transparent heat dissipation channel (hot air convection channel) from one...

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 the driving power supply (transformer) assembly, the surrounding wall of the middle cavity is sealed, and the surrounding wall of the airtight middle cavity has several shapes. The heat sinks arranged radially, the whole heat sink has no transparent heat dissipation channel (hot air convection channel) from one side to the other side, the air cannot be convected horizontally, the heat dissipation effect is poor, and the temperature of the cavity reaches above 80 degrees Celsius, which is easy to burn out Its driving power supply (transformation) components, LED chips and other components shorten the service life and greatly increase the use cost of LED energy-saving lamps. Due to the problem of heat dissipation technology, the actual service life of LED lamps is generally not as good as the theoretical value, and the cost performance is lower than Traditional lamps; 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
