The LED tube lamp is simple in structure, low in product weight and suitable for mass production; and the LED tube lamp is further good in heat dissipation effect, even in light emission and long in service life.
Description
Technical field
The utility model relates to a kind of LED Down lamp.
Background technology
The LED Down lamp is a kind of lighting that is embedded into light down-ejection type in the ceiling, and its light is more concentrated, and the light and shade contrast is strong, outstanding more illuminated object, and the lumen degree is higher, sets off out quiet ambiance more.Simultaneously, the LED Down lamp also has low-carbon (LC), energy-saving and environmental protection, economic dispatch advantage, thereby the LED Down lamp is widely used in public places such as market, hotel.
Yet the power supply cover and the lamp tube of present LED Down lamp adopt die cast, its complex manufacturing mostly; Cycle is long; Be easy to generate the shortcoming of inner loose or bad order, and product weight is big, complex structure, packaging technology are loaded down with trivial details, makes troubles to production in enormous quantities.In addition, in order to play better radiating effect, existing LED Down lamp has increased fin in the power supply cover; Though can play better radiating effect; But its quality is big, many with the attachment of lamp tube, and packaging technology is loaded down with trivial details, has increased the difficulty of producing in enormous quantities more.Moreover; The lamp tube inside of existing LED Down lamp does not add reflective sheeting or adopts increase reflection shield parts to realize effective utilization of light or make lighting effect more excellent; The former makes light can not maximize application and makes that the light diffusion is inhomogeneous that the latter need increase parts and bring problems such as corresponding structure is complicated, assembling is loaded down with trivial details when then existing power supply to be connected with the lamp tube.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of LED Down lamp of simple in structure, simple and convenient, the good heat dissipation effect of assembling is provided.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of LED Down lamp; Comprise aluminium lamp tube, be connected the aluminium power supply cover at said aluminium lamp tube top; The top of said aluminium lamp tube is provided with aluminium and closes substrate and be fixed on said aluminium and close the LED lamp on the substrate, and the bottom of said aluminium lamp tube is provided with diffuser plate, is provided with power supply in the said aluminium power supply cover.
Preferably, said aluminium power supply cover is fixed on said aluminium lamp tube top through screw.
Preferably, the middle part of said aluminium lamp tube is an arcwall face.
Preferably, also be provided with reflective sheeting in the said aluminium lamp tube.
Preferably, ring reflection shield in the bottom of said aluminium lamp tube also is provided with, said diffuser plate place said interior ring reflection shield top.
Preferably, said aluminium power supply is covered with the heat radiation window.
Preferably, also comprise the terminal box that is fixed on said aluminium power supply cover top.
The beneficial effect of the utility model is: 1, adopt the aluminium power supply cover of aluminium sheet moulding in light weight with aluminium lamp tube, both are fixedly connected through simple screw, assembling is simple, and the compact conformation of whole Down lamp, suitable production in enormous quantities; 2, aluminium power supply cover is offered the heat radiation window temperature of power supply can be shed in a large number, thereby power supply can not broken down because temperature is too high, prolongs the service life of product; 3, aluminium lamp tube middle part is long-pending for arcwall face can increase aluminium lamp tube outer surface, and the heat that makes the LED lamp send closes substrate from aluminium and strengthens to the diffusion area of aluminium lamp tube, has strengthened radiating effect; 4, establish reflective sheeting in the aluminium lamp tube, the light that LED sends to the diffuser plate diffusion, makes whole Down lamp reflective evenly through the reflective sheeting reflection; 5, be fixed with terminal box on the aluminium power supply cover, make external power supply insert leakproof in the Down lamp.
Description of drawings
Fig. 1 is the structural representation of a kind of LED Down lamp of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and practical implementation example a kind of LED Down lamp of the utility model is done further explain.
Please with reference to accompanying drawing, the LED Down lamp of the utility model comprises aluminium power supply cover 1 and aluminium lamp tube 2.Said aluminium power supply cover 1 all adopts the aluminium sheet moulding with aluminium lamp tube 2.Side at the top of aluminium lamp tube 2 is provided with connecting hole; The end of aluminium power supply cover 1 is provided with fixing hole; Aluminium power supply cover 1 is placed aluminium lamp tube 2 tops, make fixing hole and connecting hole overlapping, pass fixing hole and connecting hole with screw 14 and make aluminium power supply cover be fixed on aluminium lamp tube top.
In order to make the external power supply that is connected with power supply 1 not produce the electric leakage accident, ensure the safe in utilization of product, in aluminium power supply cover 1 upper fixed one terminal box 12.
The top of said aluminium lamp tube 2 is provided with aluminium and closes substrate 21, closes at aluminium and lays LED lamp 22 on the substrate 21.Aluminium closes substrate 22 and before being fixed to aluminium lamp tube 2, coats heat-conducting silicone grease in the bottom earlier, then aluminium is closed substrate 22 and is close to aluminium lamp tube 2 bottoms.Ring reflection shield 24 in the bottom of aluminium lamp tube 2 also is provided with.Likewise, interior ring reflection shield 24 is coated heat-conducting silicone grease in interior ring reflection shield 24 bottoms earlier before being fixed to aluminium lamp tube 2, interior ring reflection shield 24 is close to aluminium lamp tube 2 bottoms.On interior ring reflection shield 24, be provided with diffuser plate 23.
For the heat that makes LED lamp 22 send spreads quickly, the middle part of said aluminium lamp tube 2 is an arcwall face, and the heat that the LED lamp sends closes substrate 21 when aluminium lamp tube 2 spreads by aluminium, and diffusion area increases, rapid heat dissipation, good heat dissipation effect.
Penetrate on whole Down lamp for the luminous energy that LED lamp 22 is sent expands equably, also be provided with reflective sheeting 25.Said reflective sheeting 25 places aluminium lamp tube 2 inside, and an end places on the diffuser plate 23, and the other end places aluminium to close on the substrate 21.After all diffusions of the light that LED lamp 22 emits through reflective sheeting 25, be reflected on the diffuser plate, illuminate whole Down lamp equably.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
