Known lamp cooling structure has a radiating shell, when using, the light-emitting device that is provided with several light emitting diode bulbs closely is attached at the medial surface of radiating shell, when light emitting diode bulb is luminous, the heat that light emitting diode bulb produced can conduct to radiating shell, reaches the effect of heat radiation by radiating shell.
Yet known radiator structure still has shortcoming to exist, because radiating shell is all the aluminium casting, so weight is heavier, and radiating shell only is single hull, and its area of dissipation is limited, causes the heat-sinking capability deficiency.
Therefore, the utility model designer improves thoughts on above-mentioned defective, is that the spy concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
The utility model content
In view of above problem, main purpose of the present utility model provides a kind of lighting device with radiator structure, and it has preferable heat-sinking capability, so as to avoiding because overheated and cause the damage of lighting device.
To achieve the above object, the utility model provides a kind of lighting device with radiator structure, comprising: a led lamp; One radiating fin group, this radiating fin group has a plurality of radiating fins, and this radiating fin group is fixed in this led lamp; And a radiator fan, this radiator fan is fixed in this radiating fin group, and this radiating fin is mounted between this led lamp and this radiator fan.
The utlity model has following useful effect: the heat that is produced when led lamp is luminous, can conduct to the radiating fin group, because the radiating fin group has a plurality of radiating fins,, have preferable radiating effect so area of dissipation is enough.And the radiator fan of arranging in pairs or groups again, via the effect of thermal convection current, radiating effect more promotes again.Thus, can avoid led lamp because overheated and produce damage.
