Scheme is known thus, pass through thermovent, convection current is formed with outside inside Lamp cup, a large amount of heats is distributed in air, fin directly contacts with Lamp cup, a large amount of heats directly reaches Lamp cup from fin, and Lamp cup reaches in air again, and heat is reached the external world by the heat dissipation channel that fin and reflector are formed.Therefore, the heat that many heat dissipation channels LED spotlight produces can reach the external world by multiple channel, adds the radiating effect of many heat dissipation channels LED spotlight.
A kind of preferred version is the heat conduction cylinder table that many heat dissipation channels LED spotlight also comprises for fixed light source.
Scheme is known thus, and heat conduction cylinder table adds the radiating effect of light source, extends the service life of light source.
A kind of preferred version is the cross section of heat conduction cylinder table is " convex " font.
A kind of preferred version is that the quantity of thermovent is two and is symmetrically distributed in Lamp cup sidewall.
A kind of preferred version is that thermovent is positioned near heat conduction cylinder table side.
Scheme is known thus, and the heat major part produced due to light source reaches heat conduction cylinder table, and thermovent is more conducive to forming convection current with outside near heat conduction cylinder table.
Preferred version is the buckle that light source is provided with L shape, and reflector is provided with the draw-in groove of the L shape of matching with the buckle of L shape, and buckle snaps in draw-in groove and after rotation, light source and reflector are fixed.
Scheme is known thus, and buckle snaps in draw-in groove and after rotation, light source and reflector are fixed, and are convenient to the installation and removal of reflector and light source.
A kind of preferred version is light source is LED.
Scheme is known thus, and LED is a kind of energy-efficient light source.
Comprehensive technique scheme is known, and the utility model has following beneficial effect: heat radiation channel is many, good heat dissipation effect, long service life.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of description, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is exploded view of the present utility model.
Fig. 2 is schematic diagram of the present utility model.
Fig. 3 is the sectional view of Lamp cup in the utility model.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figures 1 to 3, a kind of many heat dissipation channels LED spotlight 1, comprises Lamp cup 10, is located at the reflector 30 inside Lamp cup 10 and light source 20, and Lamp cup 10 sidewall is provided with thermovent 101; Lamp cup 10 inwall axial direction is located at fin 102, forms heat dissipation channel 103 between fin 102 and reflector 30, and logical 103 roads of heat radiation are through to rear side on front side of Lamp cup 10.
Hot-air inside Lamp cup 10 forms convection current by thermovent 101 with extraneous, is distributed in air by a large amount of heats; Fin 102 directly contacts with Lamp cup 30, and a large amount of heats directly reaches Lamp cup 30 from fin 102, and Lamp cup 30 reaches in air again, and heat is reached the external world by the heat dissipation channel 103 that fin 102 and reflector 30 are formed.Therefore, the heat that many heat dissipation channels LED spotlight 1 produces can reach the external world by multiple channel, adds the radiating effect of many heat dissipation channels LED spotlight 1 lamp.
Particularly, many heat dissipation channels LED spotlight 1 also comprises the heat conduction cylinder table 105 for fixed light source 20.The cross section of heat conduction cylinder table 105 is " convex " font.Light source 20 directly contacts with heat conduction cylinder table 105, and heat conduction cylinder table 105 adds the radiating effect of light source 20, extends the service life of light source.The quantity of thermovent 101 is two and is symmetrically distributed in Lamp cup 10 sidewall.Thermovent 101 is positioned near heat conduction cylinder table 105 side.The heat major part that light source 20 produces reaches heat conduction cylinder table 105, and thermovent 101 is more conducive to forming convection current with outside near heat conduction cylinder table 105.Light source 20 is provided with the buckle 201 of L shape, and reflector 30 is provided with the draw-in groove 301 of the L shape of matching with the buckle 201 of L shape, and buckle 201 snaps in draw-in groove 301 and rotates rear light source 20 and fixes with reflector 30.Buckle 201 snaps in draw-in groove 301 and after rotation, light source 20 is fixed with reflector 30, is convenient to the installation and removal of reflector 30 and light source 20.The outboard end of reflector 30 is also provided with louvre 308, and heat can flow to the external world from louvre 308, further increases the radiating effect of reflector 30.Lamp cup 10 inwall is also provided with for fixing reflector 30 holddown groove 104, and the outboard end of reflector 30 is also provided with the clip 302 matched with holddown groove 104, and after clip 302 inserts holddown groove 104, reflector 30 and Lamp cup 10 are just fixed.Light source 20 is LED.
