Description
Technical field
The present invention relates to the LED lamp radiators in lighting area.
Background technology
LED lamp is with the excellent specific property of their own, nowadays more and more universal.It is well known that fever more is
One major issue of LED lamp, therefore each LED lamp needs to be equipped with suitable radiator, the quality of radiator performance
Directly influence the performance and used life of a LED lamp.And for there is the special LED lamp of outdoor requirement, to it
Heat spreader structures have more special requirement again.、
A kind of existing " sky spindle guide electricity as disclosed in Chinese patent CN103148468B for the outdoor LED lamp used
Modularized LED lamp honeycomb blade radiator and LED light group " discloses a kind of honeycomb gilled radiator in this document, wraps
Include radiator body, the bottom surface of radiator body is equipped with the mounting surface for installing LED light source, in mounting surface on radiator body
Periphery be provided with it is multiple along the vertical direction penetrate through radiator bodies through hole i.e. heat emission holes.Heat emission hole be mainly used for it is ventilative with
The heat of radiator body is set to shed as early as possible, while heat emission hole also has another important function, outdoors when the rainy day, rainwater can
It is gone out through heat emission hole with from top to bottom direct, avoids rainwater from accumulating on radiator body and influence heat dissipation effect, rainwater exists
The heat of radiator body can also be taken away during going out through heat emission hole.
Existing this LED lamp can be adapted for outdoor rainy day and use, but itself there is a problem in that：In order to ensure
In fine day, the great heat radiation effect of radiator is more conducive to cross-ventilation, and each heat emission hole is vertically arranged, this
Structure has reached in the preferable purpose of fine day heat dissipation effect, but when the rainy day, and due to drenching with rain, direction will appear uncertainty, lean on
Water in the heat emission hole of nearly mounting surface may splash in the LED lamp source on mounting surface and influence the service life of LED lamp source.
Invention content
The purpose of the invention is to provide a kind of LED lamp radiators, and to solve, rainwater may in the prior art
The problem on mounting surface is splashed through the heat emission hole near mounting surface.
To achieve the goals above, the technical solution adopted in the present invention is：
LED lamp radiator, including bottom are provided with the radiator body of mounting surface, in mounting surface on radiator body
Periphery be provided with multiple heat emission holes for penetrating through the radiator body along the vertical direction, the heat emission hole adjacent with the mounting surface
Bottom be communicated with splash-proof canister, side of the splash-proof canister far from the mounting surface is hinged and connected with radiator body, and splash-proof canister closes on
The side of the mounting surface is connected by bellows with the radiator body, guiding movement along the vertical direction on radiator body
Be equipped with the water receiving tank of open upper end, be provided with water receiving tank resetting spring between water receiving tank and radiator body, water receiving tank with it is anti-
It splashes between cylinder and is provided with for driving the splash-proof canister towards far from one side oscillation of the mounting surface after water receiving tank water receiving moves down
Transmission mechanism.
Splash-proof canister resetting spring is provided between splash-proof canister and radiator body.
The transmission mechanism is jointed gear unit.
Jointed gear unit includes the kinematic link being hinged and connected with the splash-proof canister, is hinged phase with the radiator body
The bottom of the transmission crank arm of v-shaped structure even, one of transmission crank arm straight-arm and water receiving tank is oriented to and is slidably matched to connect
Transmission crank arm is set to rotate by water receiving tank suppressing action when sink moves down, another straight-arm of transmission crank arm connects with the transmission
Bar is hinged and connected.
Transmission mechanism includes the gear being rotatably dispose on the radiator body and the edge that is fixedly arranged on the water receiving tank
The vertical rack with gear engaged transmission that upper and lower directions extends, transmission mechanism further includes coaxial fixed with the gear
