Abstract
The utility model discloses an LED (Light-Emitting Diode) down lamp. The LED down lamp consists of a lampshade, an LED lamp panel, an aluminum shell, a driving power supply, a plastic shell, a lamp cup and a lamp holder, wherein the upper end of the lamp cup is provided with an annular clamping groove which is matched with the lampshade; the lampshade is arranged on the lamp cup through the clamping groove; the outer wall of the lamp cup is further provided with small holes through which heat in the lamp cup is dissipated; the aluminum shell, the plastic shell, the LED lamp panel and the driving power supply are arranged in the lamp cup; the plastic shell is made of a thermoplastic material; the aluminum shell is jointed on the inner surface of the plastic shell; the LED lamp panel is arranged above the aluminum shell, and is connected with the driving power supply; the lamp holder is arranged at the lower end of the outer side of the lamp cup; the lamp holder is connected with the driving power supply. The LED down lamp disclosed by the utility model is provided with a small number of parts and is simple in structure, and the cost of the LED down lamp is reduced; moreover, by adopting the aluminum shell and the plastic shell made of the thermoplastic material, the weather resistance of the lamp is enhanced; through the small holes in the lamp cap, the heat-dissipating effect of the lamp is improved, and the service life of the LED down lamp is prolonged.
Description
Technical field
The utility model relates to a kind of LED Down lamp.
Background technology
LED Down lamp is a kind of lighting that is embedded into light down-ejection type in ceiling.With the contrast of traditional Down lamp, that LED Down lamp has advantages of is energy-conservation, low-carbon (LC), longevity, colour rendering are good, fast response time.Along with the development and progress of LED technology, the LED Down lamp performance advantage on market is very outstanding, and development prospect is considerable.But in prior art, LED cylinder lamp structure is complicated, and heat dissipation capacity is large, and weatherability is poor, and cost is high, and service life is short.
Therefore, the structure of improving LED Down lamp has great importance, and the inventor has researched and developed a kind of LED Down lamp specially, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of LED Down lamp, makes it simple in structure, and weatherability is strong, and radiating effect is remarkable, longer service life.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of LED Down lamp, by lampshade, LED lamp plate, aluminum hull, driving power, mould shell, Lamp cup and lamp holder and form, Lamp cup upper end is provided with the annular slot with lampshade adaptation, lampshade is arranged on Lamp cup by draw-in groove, on Lamp cup outer wall, be also provided with the aperture shedding for heat in Lamp cup, in Lamp cup, be provided with aluminum hull, mould shell, LED lamp plate and driving power, moulding shell is made by thermoplastic, aluminum hull is fitted in the inner surface of moulding shell, LED lamp plate is placed in aluminum hull top, and be connected with driving power, the lower end in Lamp cup outside is provided with lamp holder, and lamp holder is connected with driving power.
Described thermoplastic is polybutylene terephthalate (PBT) PBT or polycarbonate.
Adopt after such scheme, the part that the utility model not only adopts is less, simple in structure, reduced the cost of device, and adopt aluminum hull and by thermoplastic, made mould shell, strengthened the weatherability of light fixture, and by the aperture on Lamp cup, strengthened the radiating effect of light fixture, also made the longer service life of device.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is three-dimensional exploded view of the present utility model;
Fig. 2 is front view of the present utility model.
Label declaration
Lampshade 1, LED lamp plate 2, LED light emitting diode 21, aluminum hull 3, driving power 4, moulds shell 5, Lamp cup 6, draw-in groove 61, aperture 62, lamp holder 7.
The specific embodiment
A kind of LED Down lamp as shown in Figure 1, by lampshade 1, LED lamp plate 2, aluminum hull 3, driving power 4, mould shell 5, Lamp cup 6 and lamp holder 7 and form.
Lamp cup 6 is trumpet-shaped hollow structure, and its upper end is provided with the annular slot 61 with lampshade adaptation, and lampshade is arranged on Lamp cup 6 by draw-in groove 61.On Lamp cup 6 outer walls, be also provided with the aperture 62 shedding for the interior heat of Lamp cup 6.In Lamp cup 6, be provided with aluminum hull 3, mould shell 5, LED lamp plate 2 and driving power 4.Aluminum hull 3 is all horn-like with the shape of moulding shell 5, and is fitted in the inner surface of moulding shell 5.Mould shell 5 and made by thermoplastic, thermoplastic has the advantages such as resistance to ag(e)ing, temperature limit are wide, environmental protection, thereby strengthens the weatherability of light fixture.Thermoplastic is polybutylene terephthalate (PBT) PBT or polycarbonate.
The heat that LED lamp plate 2 produces can shed through aluminum hull 3.The LED lamp plate 2 of this embodiment is placed in aluminum hull 3 tops.On LED lamp plate 2, form several ringwise and symmetrical LED light emitting diode 21, and be connected with the driving power 4 in moulding shell 5, specifically can realize electrical connection by modes such as wires.Lamp holder 7 by the screw thread on its outer wall with mould shell 5 and coordinate, make lamp holder 7 be arranged on the lower end in Lamp cup 6 outsides.Lamp holder 7 is connected with driving power 4 again.
The part that the utility model not only adopts is less, simple in structure, has reduced the cost of device, and adopt aluminum hull 3 and by thermoplastic, made mould shell 5, strengthened the weatherability of light fixture, and by the aperture 62 on Lamp cup 6, strengthened the radiating effect of light fixture, also made the longer service life of device.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
