Between form heat dissipation channel.
By using above-mentioned technical proposal, because floodlight is vertically-mounted, the first radiating fin is kept and floodlight
Installation direction it is identical, heat can typically rise, and institute's shape between two the first adjacent radiating fins in heat uphill process
Into heat dissipation channel be similarly and be vertically arranged so that heat can be smoothly passed over more, avoid due to the first radiating fin its
His setting direction causes the situation that heat is blocked, further improving radiating effect.
Preferably, the bonnet also includes setting radiating wall both sides and the curved extension of outline, the expansion
Exhibition portion offers arc groove, and separator sheets are provided with the arc groove.
By using above-mentioned technical proposal, the whole width for widening floodlight of setting of extension, and then improve illumination
Projected area, and extension can equally play radiating effect, same outline is arranged to arc and increases area of dissipation, in addition
The arc groove opened up in extension can reduce material cost and overall weight, and separator sheets are in arc groove in addition
Be provided as the effect of reinforcement, will in the case where reducing weight proof strength.
Preferably, the annular seal groove for installing sealing ring is offered in the end face outer rim of the light source box.
By using above-mentioned technical proposal, bonnet after being fixed with front cover match, due to covered after open up it is annular close
Sealing groove, sealing ring can be embedded in annular seal groove, improve the sealing in both mating surfaces after protecgulum coordinates with bonnet.
Preferably, the bonnet also includes the power pack being connected with light source box, is set on the two sides of the power pack
It is equipped with support frame mounting seat.
By using above-mentioned technical proposal, the setting of support frame mounting seat can facilitate the installation of follow-up support frame, and next subtracts
Lack the contact area of power pack side and support frame surface, improve the installation accuracy of support frame, and then support frame is after adjustment
It is more accurate during lid setting angle.
Preferably, the upper edge of the light source box is provided with two the first mounting blocks, and two are provided with the power pack
Individual second mounting blocks.
By using above-mentioned technical proposal, the setting of the first mounting blocks and the second mounting blocks facilitates the installation of protecgulum.
Preferably, the lower edge of the power pack is provided with two the 3rd mounting blocks.
By using above-mentioned technical proposal, the setting of the 3rd mounting blocks facilitates the installation of power supply cover plate to fix.
In summary, the utility model has the advantages that：
1st, by the way that LED light source module is arranged on the first radiating wall so that heat is straight as caused by LED light source module
Connect and be delivered to the first radiating wall, be incorporated in the first radiating fin set on the first radiating wall and the increase of the second radiating fin
The area of dissipation of first radiating wall improves radiating effect, ensures secondly by the area of dissipation for reducing the second radiating fin two the
There is larger heat-dissipating space between one radiating fin, improve the mobility of air；
2nd, by the synchronous area for increasing reflector of setting of extension, and then the projection scope of illumination is improved, and simultaneously
Area of dissipation further is increased, plays auxiliary heat dissipation effect.
