Description

The LED Down lamp

Technical field

The utility model relates to lighting, relates in particular to the LED cylinder lamp structure.

Background technology

Down lamp is a kind of lighting that is embedded into light down-ejection type in the ceiling.Its maximum characteristics are exactly to keep the integral body of building decoration unified and perfect, can not destroy the perfect unity of furred ceiling art because of the setting of light fixture.This latent the putting property light fixture that is flush-mounted in ceiling inside, all light be projection downwards all, belongs to direct luminous intensity distribution.Down lamp does not take up space, and can increase the soft atmosphere in space, if want to build warm sensation, can try to install many Down lamps, alleviates space constriction, generally in the hotel, family, coffee shop use more.

Existing Down lamp generally is the lamp lighting that adopts incandescent lamp or electricity-saving lamp.Along with the LED(light emitting diode) development of technology, LED also is applied to the Down lamp illumination.Energy-efficient, robust advantage that LED has adopts the LED Down lamp can avoid the inconvenience of often changing.The weak point that existing LED Down lamp has is:

(1) the LED lamp plate directly is arranged on the lamp tube face, and spotlight effect is not good, influences the projection illumination effect;

(2) light that sends of LED lamp plate is concentrated inadequately, shines the waste into luminous energy;

(3) LED cylinder lamp structure complexity and radiating effect are not good, and installation and maintenance all is difficult for.

The utility model content

Therefore, the utility model is at the weak point of existing LED Down lamp, proposes that a kind of LED is efficiently luminous, optically focused projection effect is better and the LED Down lamp simple and easy, that radiating effect is good is installed.

The technical solution of the utility model is:

The LED Down lamp comprises:

One cylindrical shell is made up of nozzle and the barrel of centre and the fixed cover of lower end of upper end, and the inner surface of fixed cover is provided with screw thread;

One base plate which is provided with a plurality of through holes;

One connects foundation, and the upper end that connects foundation is that the fixed bolt that outer surface is provided with screw thread partly should have concave space on connection foundation;

One LED lamp plate which is provided with a plurality of LED lamp holders, and the LED lamp plate is fixed in the following concave space of above-mentioned connection foundation;

Wherein, above-mentioned base plate is located at and is connected foundation and LED lamp plate top, and the position corresponding to the LED lamp holder on the LED lamp plate of the through hole on the base plate, and the fixed bolt of above-mentioned connection foundation upper end partly screws the fixed cover that is fixed in the cylindrical shell lower end.

Preferably, the surface of the barrel of described cylindrical shell and base plate is the frosted shape.The barrel of cylindrical shell and the surface of base plate adopt the frosted shape can increase the diffuse reflection of light, can make light softer.

Preferably, the distribution mode of the LED lamp holder on the described LED lamp plate is middle LED lamp holder, equidistant 5 the LED lamp holders that evenly distribute of its periphery.The LED lamp holder distribution mode of " plum blossom " shape can make the light-illuminating effect of LED more even like this.

Preferably, the top of the LED lamp holder on the described LED lamp plate also is provided with collector lens.By the setting of collector lens, the light of LED lamp holder better can be assembled, thereby be avoided the waste of luminous energy.

The utility model adopts as above technical scheme, fixes by the screw thread mode of screwing of cylindrical shell, base plate, connection foundation and LED lamp plate, and is simple and reliable for structure, is convenient to installation and maintenance.The utility model throws after utilizing the light diffuse reflection of barrel with the LED lamp plate of cylindrical shell, and illuminating effect is excellent.And the LED lamp plate, top of the present utility model also is provided with collector lens.By the setting of collector lens, the light of LED lamp holder better can be assembled, thereby be avoided the waste of luminous energy.In addition, cylindrical shell of the present utility model, base plate, connection foundation all are to adopt aluminum material to make, and be not only sturdy and durable and heat transfer efficiency is better.

The specific embodiment

Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.

Consult Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, LED Down lamp of the present utility model comprises:

One cylindrical shell 1 is made up of nozzle 11 and the barrel 12 of centre and the fixed cover 13 of lower end of upper end, and the inner surface of fixed cover 13 is provided with screw thread;

One base plate 2 which is provided with a plurality of through holes 2;

One connects foundation 3, and the upper end that connects foundation 3 is that fixed bolt part 31 these connection foundation 3 upper ends that outer surface is provided with screw thread have concave space 32;

One LED lamp plate 4 which is provided with a plurality of LED lamp holders 5, and LED lamp plate 4 is fixed in the following concave space 32 of above-mentioned connection foundation 3;

Wherein, above-mentioned base plate 2 is located at and is connected foundation 3 and LED lamp plate 4 tops, and the position corresponding to the LED lamp holder 5 on the LED lamp plate 4 of the through hole on the base plate 22, the fixed bolt part 31 of above-mentioned connection foundation 3 upper ends screws the fixed cover 13 that is fixed in cylindrical shell 1 lower end.
