Description

The LED Down lamp

Technical field

The utility model relates to the illumination and decoration field, relates more specifically to a kind of LED Down lamp.

Background technology

Led light source because of it has that volume is little, energy consumption is low, long service life, photochromic pure, brightness is high, heat is low and characteristics such as environmental protection low-carbon (LC), is the 21 century novel green light source of generally acknowledging in the world.Along with the continuous development of science and technology, the application of led light source also more and more widely.In recent years, led light source is also increasing is applied in building indoor and outdoor, urban beautification, the landscape garden to play the effect of decorative lighting.

In numerous LED decorating lighting lamps, the LED Down lamp is more common a kind of.Existing LED Down lamp generally comprises led light source, led driver and shell, and said led light source and led driver all are installed in the said shell, and said led driver connects and drives said led light source.The general spot light that adopts of said led light source part, one one lamp pearl naked eyes are visible, and as accomplishing the high-power of 10w, its light efficiency is relatively poor, and radiating effect is also poor.In addition, said shell generally adopts metal material to make, and makes that the weight of whole LED Down lamp is bigger, is not easy to assembling, dismounting, packing and transportation, makes also that simultaneously the cost cost of whole LED Down lamp is higher.

Therefore, be necessary to provide a kind of improved LED Down lamp to overcome above-mentioned defective.

The utility model content

The purpose of the utility model provides a kind of LED Down lamp, and the bottom and the lamp housing of said LED Down lamp are plastic cement material, makes that the weight of said LED Down lamp is lighter, be convenient to assembling, dismounting, packing and transportation, and the cost cost is lower.

For realizing above-mentioned purpose; The utility model provides a kind of LED Down lamp; Comprise led driver, bottom, radiator, reflector, led light source, reflector, LED gland, diffuser plate and shell; Said led driver is installed in the upper surface of said bottom and is connected with said led light source through cable; Said radiator and reflector are installed in the lower surface of said bottom successively; Said led light source and reflector are installed in the said reflector successively, and said LED gland is installed in the said reflector and further pushes down said reflector, and said diffuser plate is covered in the opening part of said reflector and pushes down said LED gland; Said shell is installed on the said bottom and with said bottom and forms an accommodation space, and said radiator, reflector, led light source, reflector, LED gland and diffuser plate all are placed in the said accommodation space.Wherein, said bottom and shell are the plastic cement structure.

Compared with prior art,, make that the weight of said LED Down lamp is lighter, be convenient to assembling, dismounting, packing and transportation, and the cost cost is lower because the bottom and the shell of the utility model LED Down lamp are the plastic cement structure.

Preferably, said led light source is an area source.The light that said area source sent is even, soft, attractive in appearance, and light efficiency is better than general spot light, thereby has improved the power of whole LED Down lamp.In addition, the use of said area source makes that the radiating effect of whole LED Down lamp is better.

Particularly, said radiator comprises the cylinder of a hollow structure, and said cylindrical outer surface outwards vertically protrudes out complex cooling fin, and complex cooling fin is equidistant arrangement.The radiator structure of sheet has further strengthened the radiating effect of whole LED Down lamp.

Particularly, said reflector is bowl-shape.

Particularly, said reflector and diffuser plate are all rounded.Circular reflector and diffuser plate are to adapt to bowl-shape reflecting cup structure; Like this; Not only saved material, and be convenient to the reflector that fits together, led light source, reflector, LED gland and diffuser plate are assembled in said bottom and the formed accommodation space of shell.

In a preferred embodiment of the utility model, said LED Down lamp also comprises and protects cableties, saidly protects the upper surface that cableties are installed on said bottom, and said cable passes the said cableties that protect.Can adopt cable that said led driver and led light source are linked together so more easily, thereby make things convenient for the assembling of LED Down lamp.

Preferably, said LED Down lamp also comprises two shell fragments, and two said shell fragments are installed on the both sides of said shell respectively.The setting of said shell fragment local more is installed on ceiling etc. with said LED Down lamp.

Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.

Description of drawings

Fig. 1 is the three-dimensional structure diagram of the utility model LED Down lamp.

Fig. 2 is the exploded view of Fig. 1.

The specific embodiment

With reference now to accompanying drawing, describe the embodiment of the utility model, the similar elements label is represented similar elements in the accompanying drawing.As stated, the utility model provides a kind of LED Down lamp, because the bottom and the shell of said LED Down lamp are the plastic cement structure, makes that the weight of said LED Down lamp is lighter, be convenient to assembling, dismounting, packing and transportation, and the cost cost is lower.

Please refer to Fig. 1 and Fig. 2; One embodiment of the utility model LED Down lamp comprises led driver 10, protects cableties 12, bottom 14, radiator 16, reflector 18, led light source 20, reflector 22, LED gland 24, diffuser plate 26, shell 28 and two shell fragments 30; Said led driver 10 with protect the upper surface that cableties 12 are installed in said bottom 14; One end of one cable (figure does not show) connects said led driver 10; The other end of said cable passes and saidly protects cableties 12 and be connected with said led light source; To realize the driving of 10 pairs of said led light sources 20 of said led driver; Said radiator 16 and reflector 18 are installed in the lower surface of said bottom 14 successively, and said led light source 20 is installed in the said reflector 18 with reflector 22 successively, and said LED gland 24 is installed in the said reflector 18 and further pushes down said reflector 22; Said diffuser plate 26 is covered in the opening part of said reflector 18 and pushes down said LED gland 24; Said shell 28 is installed on the said bottom 14 and forms an accommodation space with said bottom 14, and said radiator 16, reflector 18, led light source 20, reflector 22, LED gland 24 and diffuser plate 26 all are placed in the said accommodation space, and two said shell fragments 30 are installed on the both sides of said shell 28.
