Description
Technical field
The utility model relates to a kind of light fixture, relates in particular to a kind of Down lamp.
Background technology
Down lamp is on the market done the in the majority of shell with die casting aluminium, face ring die casting aluminium, and radiator die casting aluminium, casting forming need be done multiple tracks postprocessing working procedures just can obtain final part, so cost is very high.Yet small-power SMD is quite ripe, and caloric value is very little, moderate if lamp pearl is arranged, and can realize the radiator that does not need die-casting die completely.Down lamp need be done embedded installation, and jump ring fixture is installed need bear twisting resistance, must accomplish sufficient intensity, to strong structure part is too much, causes assembling complicated herein on the market.Down lamp radiator is handware, in order to guarantee to install, needs ground connection, but a lot of Down lamp all not have processing so on the market, possesses certain potential safety hazard.In addition, Down lamp light-emitting area is larger, and Down lamp on the market does not form enough attention to dustproof, thereby causes Down lamp easily to enter ash, affects visual effect.
Utility model content
Technical problem underlying to be solved in the utility model is to provide a kind of Down lamp, when having guaranteed radiating effect and intensity, has saved metal consumption, and Down lamp is prevented dust and grounding.
In order to solve above-mentioned technical problem, the utility model provides a kind of Down lamp, comprising:
Face ring, has an installation portion on described ring, and on described installation portion, draw-in groove is installed in rotation; The side that draw-in groove is installed in described rotation is equipped with reinforcement;
Fixture, described fixture is by injection moulding integrated molding process Installation in the side of described installation portion, and described fixture is provided with spring clip away from one end of described ring;
Radiator, the side of described radiator is provided with installation salient point, and the position of described installation salient point and size are corresponding with described rotation installation draw-in groove; On described radiator, there is an earth terminal;
Power pack, described power pack is arranged on the top of described radiator, and makes described earth terminal ground connection;
The interior ring of described ring is provided with dust ring with the part that described radiator bottom contacts.
In a preferred embodiment: have at least one mould filling hole on described fixture, described mould filling hole, when injection moulding integrated molding technique, can make described fixture and described ring bonding strength higher.
In a preferred embodiment: described mould filling hole is three, be located at respectively both sides and the bottom of described fixture.
In a preferred embodiment: described radiator is spinning part.
In a preferred embodiment: the side of described power pack is recessed moulding with respect to the top of power pack.
Compared to prior art, the utility model possesses following beneficial effect:
1. a ring adopts plastic material, the loss of having saved aluminium.Fixture and face ring adopt injection moulding integrated molding technique, have guaranteed the bonding strength of fixture and face ring.In fixture, offer mould filling hole, further strengthened the bonding strength of fixture and face ring.
2. radiator adopts spinning part, compared to traditional die casting, and the thin thickness of spinning part, good heat dissipation effect.
3. radiator is provided with ground hole, has increased the safe class of Down lamp.
4. a ring and radiator contact portion are provided with dust ring, have avoided Down lamp because entering ash, to affect visual effect and illumination effect.
Accompanying drawing explanation
Fig. 1 is the overall appearance figure of the utility model preferred embodiment;
Fig. 2 is the structural representation of face ring and radiator during the utility model is preferably implemented;
Fig. 3 is the scheme of installation of face ring and radiator in the utility model preferred embodiment;
Fig. 4 is the schematic diagram of fixture in the utility model preferred embodiment.
The specific embodiment
Below in conjunction with the accompanying drawings and embodiments the utility model is described further.
With reference to figure 1-3, a kind of Down lamp, comprising:
Face ring 1, has an installation portion 11 on described ring 1, and on described installation portion 11, draw-in groove 111 is installed in rotation; The side that draw-in groove 111 is installed in described rotation is equipped with reinforcement 112;
Fixture 12, described fixture 12 is by injection moulding integrated molding process Installation in the side of described installation portion 11, and described fixture 12 is provided with spring clip 121 away from one end of described ring 1;
Radiator 2, the side of described radiator 2 is provided with installs salient point 21, and the position of described installation salient point 21 and size are corresponding with described rotation installation draw-in groove 111; On described radiator 2, there is an earth terminal 22;
Power pack 3, described power pack 3 is arranged on the top of described radiator 2, and makes described earth terminal 22 ground connection;
The interior ring of described ring 1 is provided with dust ring 13 with the part that described radiator 2 bottoms contact.
In the present embodiment, fixture 12 adopts the technique of injection moulding integrated molding to fix with face ring 1, makes fixture 12 very high with the bonding strength of face ring 1, in traditional Down lamp, fixture and face ring is adopted to the mode being screwed, the scheme bonding strength of the present embodiment is high, and technique is simple.
Face ring 1 has adopted plastic material, having guaranteed, under the prerequisite of working strength, to have saved metal materials, has reduced cost.
Radiator 2 is fixedly connected with the mode of installation portion 11 by pivoting latch, the mode of screw locking for contrast tradition, and the present embodiment connected mode is simple, dismantles also very convenient.Radiator 2 is provided with earth terminal 22, the potential safety hazard of having avoided metal heat sink 2 to exist.
Add dust ring 13, effectively avoided dust to enter into Down lamp inside.
With reference to figure 4, this enforcement also possesses following characteristics: on described fixture 12, have at least one mould filling hole 122, be preferably 3, and be distributed in two sides and the bottom of described fixture 12.Described mould filling hole 122, when injection moulding integrated molding technique, can make described fixture 12 higher with described ring 1 bonding strength.
Described radiator 2 is spinning part, and thickness is 0.8mm, according to hot propagation formula:
By upper formula, can be drawn: shed speed and the heat conduction thickness of heat are inversely proportional to, and the spinning part thickness that the present embodiment adopts is only 0.8mm, compares the 2mm of traditional die casting, can make undoubtedly heat shed as early as possible.
The side of described power pack 3 is recessed moulding with respect to the top of power pack.Can increase like this plastic cement intensity of power pack, thereby by shock-testing.
The above, it is only utility model preferred embodiment, not the technical scope of utility model is imposed any restrictions, therefore any trickle modification that every foundation technical spirit of the present utility model is done above example, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
