The high-power LED fluorescent lamp comprises a radiating body, LED lamps, a print circuit board (PCB), a lamp shade, drive power sources, lamp caps and lamp holders, wherein, the LED lamps are welded on the PCB to form an LED array; the PCB is bonded on the radiating body through an insulating heat conducting pad layer; the radiating body and the lamp shade form a hollow lamp tube through a clamping structure; the drive power sources are arranged in the lamp holder and are electrically connected with the PCB; and the lamp holders are fixedly sleeved on the two ends of the radiating body; and the lamp caps are sleeved on the outer ends of the lamp holders. The high-power LED fluorescent lamp provided by the utility model has simple structure; and through the additionally arranged insulating heat conducting pad layer below the PCB, heat quantity emitted by the LED lamps can be conducted to the radiating body fast, which greatly improves radiating effect, and ensures that the luminous performance is stable and the service life is long.

Description

A kind of high-power LED daylight lamp

Technical field

The utility model relates to lighting technical field, and a kind of high-power LED daylight lamp is provided.

Background technology

Led light source has long characteristics of luminous efficiency height, power saving and life-span, and it is used more and more widely.The LED fluorescent lamp is to adopt the led light source technology, compare with common fluorescent lamp, the LED fluorescent lamp with of fine quality, durable, energy-conservation be main feature, and it is almost non-maintaining, need not often to change fluorescent tube, ballast and starter, have advantages such as the crevice projection angle adjustable range is big, brightness big, high temperature resistance, be widely used in room lightings such as office building, factory, market, school, house.Because the luminous quantity of single LEDs is limited, need adopt intensive setting of a plurality of LED to concentrate use during as the LED fluorescent lamp.And the heat that the intensive use of LED can cause LED to produce accumulates in the less space in a large number, can not in time distribute, and causes the LED temperature to raise, especially high-powered LED lamp, can cause LED luminescent properties instability, the meeting light decay that works long hours is and aging rapidly, and reduce service life greatly.

The utility model content

At above the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high-power LED daylight lamp, and it is simple in structure, good heat dissipation effect, stable luminescent property, long service life.

The technical scheme that the utility model adopted is: a kind of high-power LED daylight lamp, comprise radiator, LED lamp, PCB circuit board, lampshade, driving power, lamp cap and lamp holder, wherein, described LED lamp is welded on the PCB circuit board and forms led array, described PCB circuit board is bonded on the radiator by the insulating heat-conductive bed course, described radiator and lampshade form the fluorescent tube of hollow by snap-in structure, described driving power is arranged in the lamp socket and with the PCB circuit board and electrically connects, described lamp socket fixedly is placed in the two ends of radiator, and lamp holder is placed in the lamp socket outer end.Wherein, described insulating heat-conductive pad is a silicone insulation heat conduction pad.

Further, the lateral surface of described radiator is provided with a plurality of grooves, forms heat radiating fin structure.The both sides of radiator are the groove edge of projection, and the edge of opening of described lampshade is provided with draw-in groove, and the formation snap-in structure matches with radiator groove edge.

Further, described lampshade has light scattering structure, and its inner surface has light scattering layer.

The high-power LED daylight lamp that the utility model provides, simple in structure, by below the PCB circuit board, setting up the insulating heat-conductive bed course, the heat that LED can be sent is transmitted on the radiator rapidly, improved radiating effect widely, made stable luminescent property, long service life.
