Description

A kind of LED light fixture

Affiliated technical field

The utility model relates to a kind of LED light fixture, is to the enhancing and the improvement of existing LED light fixture, belongs to LED decorative lighting field.

Background technology

Along with LED optical semiconductor source technology progressively improve and ripe, and the popularizing of energy-conserving and environment-protective low-carbon (LC) notion, led light source will progressively replace the conventional light source such as neon light that bulb, electricity-saving lamp, fluorescent lamp and advertisement are used.

L E D light source has that volume is little, optically focused directive property, fast, the characteristics such as the life-span grow, does not glimmer of lighting a lamp, especially because volume is little, and compound mode that must the many luminous points of employing.Reach uniform illumination, reduce dazzle, all must dispose L E D lamp from different perspectives.

Some LED lamp pearls on traditional LED light fixture substantially all are to be serially connected by circuit board in the mode that constant current drives, and the monoblock circuit board is fixed in the lamp housing then.The light-emitting area that this special structure must define light fixture is necessary for plane (because circuit board must be flat), but be main lighting many times as functional and sight, the light-emitting area of light fixture need be curved surface or other nonplanar structures, and this also is a critical defect of traditional LED light fixture.Secondly, traditional LED light fixture makes that light fixture optically focused is strong because some LED lamp pearls are concentrated in together, and allows the people feel dazzle and dazzling.Can not get good guarantee as its astigmatism of lighting.Secondly, the distribution that the lamp pearl is too concentrated makes the heat dispersion of whole light fixture have a greatly reduced quality, thereby influences the anti-light decay performance of light fixture, causes lamp life to reduce.

Summary of the invention

Single in order to overcome existing LED lamp luminescence face, the pattern dullness, manufacturing procedure is loaded down with trivial details and material cost and the high shortcoming of processing cost, can more convenient, more succinct Development and Production go out more cost performances light fixture higher, more Suresh Kumar and structure and be applied in the every field, the spy provides a kind of improved Novel LED lamp.

The concrete scheme that this utility model adopted is: light fixture is made up of face-piece and LED unit and electric power driving module.Wherein, face-piece is made of basic shell and some buckles unit, and basic shell is the carrier of buckle unit and LED unit, and basic shell can be made different shape, size and arbitrary surface; Each buckle unit is made up of at least one penetrating hole and some buckles of being centered around around the penetrating hole.The LED unit can be single LED lamp pearl, also can be single or the plurality of LEDs lamp pearl of welding or being fixed on the circuit carrier plate (comprising circuit board, aluminium base etc.).Make the penetrating hole of each LED unit by the face-piece back side LED lamp pearl light head expose front (light-emitting area) at face-piece, each LED unit is by firm being fixed together with face-piece in corresponding buckle unit, and all LED unit are connected on the corresponding electric power driving module with the mode that combines in parallel according to serial or parallel connection or series connection by LED pin or lead.

The shape and size in described penetrating hole are exposed head and are advisable can not make the LED unit pass completely through lamp pearl that face-piece can make the LED unit again.

Described buckle unit and basic shell are made of one, and perhaps the buckle unit is independent separating component with respect to basic shell.When buckle unit and basic shell were made of one, the LED unit was directly embedded in the buckle unit, and the lamp pearl exposes front at face-piece by penetrating hole, makes firm being assembled together of LED unit and face-piece.When the buckle unit is independent separating component, the buckle unit is made of interior buckle, outer buckle and penetrating hole, the base shell is provided with a shape and sizeable installing hole in the position of each assembling buckle unit, be used for making the buckle unit to see through this hole and be fixed together by himself outer buckle and basic shell, again the LED unit is embedded in the buckle unit, LED lamp pearl also exposes front at face-piece by penetrating hole, just interior buckle and firm being assembled together of face-piece by the buckle unit of LED unit like this.

LED lamp pearl in the described LED unit is direct insertion LED lamp pearl or adopting surface mounted LED lamp pearl or the large-power LED light bead that has two pins.All connect by lead between the LED unit, lead can be the pin of LED lamp pearl, also can be electric wire.

Can be according to concrete needs, can on the face-piece of light fixture, install a little diffuser additional in each luminous point place, LED unit, perhaps each LED cell enclosure can be the LED cell enclosure that has little diffuser, also can cover on whole face-piece outside with a big astigmatic lampshade with the face-piece coupling; Light fixture can add the lamp holder of casing and standard at the face-piece periphery; Circuit board (the comprising aluminium base) back side of welding LED lamp pearl can install radiating module additional in the LED unit.

Good effect of the present utility model is as follows: at first, can solve present LED light fixture outward appearance single, of low grade, the design circumscribed drawback is arranged: by design to the light fixture face-piece, can be processed into different shape and arbitrary surface and virtually any size to the light-emitting area of light fixture, make the outward appearance intention of light fixture unlimited, outside satisfying the most basic lighting demand, can add various fashion elements, make the LED light fixture have artistry more, satisfy the illumination or the decoration demand of all kinds of occasions.Secondly, no matter be one face-piece or with the buckle unit of basic shell separate design, its special construction can pass through the large batch of depanning of automatic injection machine fully, promotes production efficiency greatly.Moreover, by the buckle unit that designs on the light fixture face-piece and the special construction of LED unit, can make the LED unit under the situation of need not any securing member (such as screw) or not sticking with glue, can be fixed on the face-piece of light fixture easily, and need not or use circuit board (minimum can be less with 70% circuit board) fully less, like this, when having saved material cost, on the production and processing link, also save several roads manufacturing procedure, thereby the whole cost reduction of light fixture is also enhanced productivity greatly; The modular type open architecture of last this particular design of the present invention makes the LED light fixture can use up distribution density, heat-delivery surface and the heat-dissipating space that may disperse and enlarge LED or LED unit greatly, makes light fixture can improve the performance of anti-light decay greatly; Because the processing of circuit board belongs to heavy polluted industry, the present invention makes the environmental protection notion of led light source more outstanding by without circuit board or use circuit board, whole light fixture to reuse to greatest extent less or the ratio of salvage material improves.With light fixture of the present invention and method can produce more energy-conserving and environment-protective fully, cost is lower, the various application lights that light efficiency is better, cost performance is higher are applied to each lighting fields such as domestic lighting, advertising lighting, commercial illumination.
