Description

A kind of new structure LED Down lamp

Technical field

the utility model discloses a kind of new structure LED Down lamp, belong to LED applied technical field.

Technical background

down lamp is a kind of lighting that is embedded into light down-ejection type in ceiling.Its maximum feature is exactly to keep the integral body of building decoration unified and perfect, can not destroy because of the setting of light fixture the perfect unity of furred ceiling art.This hidden the putting property light fixture that is flush-mounted in ceiling inside, all light is projection downwards all, belongs to direct luminous intensity distribution.Can, with different reflectors, eyeglass, shutter, bulb, obtain different light effects.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 hotel, family, coffee shop use more.

down lamp is the product that application Novel LED illuminating light source improve exploitation on traditional Down lamp basis, contrasts and has the following advantages with traditional Down lamp: energy-conservation, low-carbon (LC), longevity, colour rendering are good, fast response time.The design of LED Down lamp is more attractive in appearance light and handy, can reach and keep the integral body of building decoration unified and perfect during installation, does not destroy the setting of light fixture, and it is inner that light source is hidden building decoration, and light source does not expose, free from glare, and people's visual effect is soft, even.Sum up and get up to have following benefit: 1, use LED Down lamp more attractive in appearance by house ornamentation.Down lamp helps the integral body of holding chamber interior trim unified and perfect, does not destroy the setting of the light fixtures such as pendent lamp, and it is inner that light source is hidden in decoration, do not expose, and free from glare, LED light source is more soft, even to people's visual effect.2, the energy saving of LED helps family to reduce electric cost expenditure: 1/4, one LED Down lamp that equal brightness power consumption is common energy-saving lamp can be one family one month can power cost saving dozens of yuan.3, LED Down lamp is non-friable, recyclable, and the feature of environmental protection is strong: the harmful substance such as not mercurous, environmentally safe.And its province electrically, is equivalent to reduce carbon emission amount.Meet the popularization of the life idea of " energy-saving and emission-reduction ".4, the longevity of LED Down lamp: the life-span of LED light fixture is 50,000 hours, is used 12 hours every day, is exactly the life-span of 10 years.This can be family and purchases light fixture and reduced by a considerable cost.

because Down lamp need to combine together with finishing, so require it thinner, because LED light source is point-like, need to make improvements from light efficiency, in addition because LED light source self-radiating is not good, so need the improvement of our cylinder lamp structure to increase its radiating effect.

Summary of the invention

inventor's of the present utility model goal of the invention is, a kind of new structure LED Down lamp is provided, and can effectively reduce the thickness of existing Down lamp, can improve LED light source heat radiation, and make LED light source bright dipping more even.

the utility model LED Down lamp comprises power supply, lamp body, LED light source, cover of upholstery, LGP, reflector plate and diffuser plate, wherein LED light source is arranged on lamp body sidewall, reflector plate is arranged at above the power supply of lamp body bottom, above reflector plate, be followed successively by LGP, diffuser plate and cover of upholstery, the light of LED light source transmitting is entirely via LGP bright dipping, LGP is acryl or the PC sheet material that is selected from optical grade, by Qi bottom surface, with UV screen printing technology, stamp light guiding points, utilize optical grade acryl or PC sheet material to draw the stop at plate surface from LED light source light out, when light is mapped to each light guiding points, reverberation can be toward all angles diffusion, then destroying conditioned reflex penetrates by LGP is positive.By various density, light guiding points not of uniform size, can make LGP uniformly light-emitting.Being provided with effectively of reflector plate returned the light of reflection to import in LGP, for improving the whole light extraction efficiency of LED Down lamp.Secondly by LED light source being arranged to lamp body sidewall, can be conducive to the thermal diffusion of LED light source under in working order, effectively reduce the operating temperature of LED light source, reduced the risk of LED light source fluorescent material because of the too high inactivation of operating temperature, the service life of directly having improved LED light source.Sidewall arranges light source, because it only penetrates by LGP, do not need the bright dipping quality problems of considering that the distance between light source and lampshade is brought, so sidewall arranges the thickness that light source can effectively reduce LED Down lamp on the other hand, during installation, can reach and keep the integral body of building decoration unified, do not destroy the setting of light fixture, it is inner that light source is hidden building decoration, and light source does not expose.

the utility model LED Down lamp sidewall adds reflecting piece, can effectively improve the light extraction efficiency of the LED light source of sidewall setting.

lED light source of the present utility model can be divided into 2 places or 2 places are arranged on the sidewall of Down lamp above, light source between adjacent two places is arranged in lamp body sidewall by uniform distances, each light source is consistent with lamp body sidewall angulation, and make LED light source prolong level to LGP bright dipping, light beam on the limit of LED light source each several part, wherein shine to sidewall reflects sheet on one side, another side prolongs LGP diameter and injects LGP.If the direct at right angle setting of LED light source in sidewall bright dipping design sketch as shown in Figure 4, certainly will there is light and shade region under in working order in light source, and because each LED all points to central authorities, cause middle section excessively bright, so the utility model everywhere light source all arranges by certain angle, and each light source is wherein shone to sidewall reflects sheet on one side, another side prolongs LGP diameter and injects LGP, each Shu Guang comprise by LED light source direct projection, gone out and via reflector plate reflection, can be uniformly distributed in LGP.

for shortening the range of light, reduce the loss of light, light conducting plate structure must with the inner joint match of Down lamp so that light just directly enters LGP after penetrating from LED light source.For improving the light-emitting uniformity of Down lamp, LGP is preferably special-shaped LGP, and in sidewall and the reflection unilateral increase patterned structures (diffusion site) of LGP, LGP is except bottom exiting surface is plane, and other faces all can be patterned structures.
