Detailed Description
In order to solve the invasion of the unable steam of avoiding of general adoption fan convection heat dissipation's projecting lamp, the problem of the internal component risk of damaging that wets exists, provides lid behind the dampproofing projecting lamp.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, this embodiment provides lid behind dampproofing projecting lamp, including lid 1, drive power supply 2 and terminal box 3, 2 electric connection terminal boxes of drive power supply 3, the 1 outside of lid is provided with leads rain groove 4, and 1 central authorities of lid are provided with louvre 5, louvre 5 below is provided with logical groove 6, it has storage check 7 to slide in logical groove 6 to cup joint, be provided with hygroscopic agent 8 in the storage check 7, still be provided with the screw 9 that is used for fixed drive power supply 2 on the lid 1 and be used for installing the wiring bayonet 10 of terminal box 3. The driving power supply 2 may be an LED power supply on the market such as a bright weft switch power supply LPV-60-24 (relevant link: https:// detail.tm. all.com/item. htm. The storage compartment 7 is of a drawer-type design and can be pulled out of the through slot 6 in order to replace the moisture absorbent 8 therein. The moisture absorbent 8 may be a relatively durable moisture absorbent such as a high-density quicklime block (relevant link: https:// item. taobao.com/item. htm.
The top of the cover body 1 is provided with a rain shielding sheet 11, and the top of the rain shielding sheet 11 is provided with a second rain guiding groove 41 communicated with the rain guiding groove 4. The rain-shielding sheet 11 can prevent water drops above the cover 1 from entering the heat dissipation holes through the heat dissipation holes 5, and the second rain guiding groove 41 can guide most of the water drops on the surface of the rain-shielding sheet to the rain guiding groove 4 for discharging.
The openings of the rain guide grooves 4 are arranged at the left side and the right side of the cover body 1. Because the rain guide grooves 4 are arranged on the two sides of the cover body 1, water flows mainly flow out from the two sides of the cover body 1, and water can be prevented from flowing down from the front surface of the cover body 1.
The inner side of the heat dissipation hole 5 is provided with a heat dissipation fan 12, and the air outlet of the heat dissipation fan 12 is arranged corresponding to the heat dissipation hole 5. The heat dissipation fan 12 blows air out of the heat dissipation holes 5, so that the heat inside the cover 1 can be rapidly discharged.
The screw hole 9 is arranged below the through groove 6, and one end of the screw hole 9 corresponding to the outer side of the cover body 1 is sealed. A connection hole corresponding to the screw hole 9 is generally reserved on the driving power supply 2 so as to fix the driving power supply 2. Because drive power supply 2 is located logical 6 belows, the outside air that gets into through louvre 5 contacts with drive power supply 2 again behind moisture absorbent 8, can effectively avoid drive power supply 2 to wet.
The inner side of the wiring bayonet 10 is connected with a butt joint groove 14, and the junction box 3 is sleeved on the inner side of the butt joint groove 14. The design that the junction box 3 is sleeved in the butt joint groove 14 can improve air tightness and prevent water vapor from entering the interior of the equipment.
The foregoing is a more detailed description of the present invention, and it is not intended that the present invention be limited to the specific details, since modifications and variations will be apparent to those skilled in the art.
