Description

FIELD OF THE INVENTION

[0001] The invention relates to the technical field of LED lighting, and more particularly to an assembled LED luminaire.

BACKGROUND OF THE INVENTION

[0002] LED is known as an environmentally friendly light source and is widely used due to the characteristics of small volume, low power consumption, long service life (ten times that of traditional light sources), high brightness, low heat emission, no toxicity, energy saving, environmental friendliness, etc., and LED is also gradually becoming an emerging light source for replacing traditional light sources.

[0003] With the rapid development of LED technologies, there are various structures and application forms for existing LED luminaires. Generally, a traditional LED luminaire is an integral luminaire in which a lamp body equipped with such components as a transparent lamp shade and an LED light source is directly fixedly connected with a lamp holder. Such LED luminaire can be used after being electrically connected with an external power source via the lamp holder, or a plurality of LED luminaires are fixedly connected with a lamp bracket via the lamp holder and then combined into a high-brightness luminaire. However, it is found that such assembled structure and the service performances thereof have disadvantages during practical use.

[0004] On one hand, for the integral LED luminaire as described above, an LED lighting luminaire with different power need to be constantly replaced or its external shape needs to be re-designed and fabricated due to different requirements on the lighting brightness and lighting luminaire shape, which tends to cause resource waste due to insufficient flexibility as well as time and labor consumption during use. Especially for a decorative LED luminaire, the luminaire is not just a lighting tool and also should have a decorative function, thus the existing LED luminaires which have single shapes and are incapable of arbitrarily changing shapes have unideal and rather monotonous decorative effects in addition to inconvenience and inflexibility in assembly, which affects the popularization and application of LED lighting luminaires. Moreover, when a plurality of the integral LED luminaires as described above are fixedly connected with a lamp bracket mounted on a wall via a lamp holder, it is inconvenient to repair or replace the LED luminaires if desired, thus increasing the complexity in mounting and disassembly between the LED luminaires and the lamp bracket.

[0005] On the other hand, the existing LED luminaires can only illuminate towards one direction or one plane such that the LED luminaires have single illumination and the illumination scope cannot be arbitrarily changed, thus affecting the utility of the LED luminaires. Moreover, the singleness of the illumination angle remains a problem for a lighting manner in which a plurality of the integral LED luminaires as described above are fixed on the lamp bracket. Although there are some LED luminaires with changeable illumination angles at the present stage, the LED luminaires also need to be additionally connected with a power connector during use so as to realize the electrical connection of the LED luminaires, thus not only the convenience in use of the LED luminaires is greatly reduced to allow the complexity of a connection structure, but also multi-component connection will directly affect the space occupied by the LED luminaires during use; in this way, a luminaire formed by combining a plurality of LED luminaires and a lamp bracket will have such problems as a large volume, a complex structure and complex mounting procedures, thereby limiting the application place and scope of the LED luminaires.

[0006] The above disadvantages greatly limit the development, popularization and application of LED luminaires. Accordingly, it is necessary to make corresponding improvements on the structures of LED luminaires such that the LED luminaires facilitate extensive use on the market to meet consumers' demand.

SUMMARY OF THE INVENTION

[0007] An objective of the invention is to overcome the defects and disadvantages in the prior art, and provide an assembled LED luminaire which has a simple and compact structure, is flexible and simple to operate, and facilitates mounting and disassembly; wherein the assembled LED luminaire can be conveniently assembled into different luminaire shapes for different needs, thereby reducing cost and facilitating wide popularization and use. A further objective is to provide an assembled LED luminaire which has an arbitrarily adjustable illumination angle, provides high convenience in use and occupies a small space when in use.To achieve the above objective, the invention is realized by the following technical solution: an assembled LED luminaire is characterized by comprising a lamp cartridge with a built-in accommodating cavity, an electrical connection member and a lamp body; wherein one end of the electrical connection member is detachably connected with the lamp cartridge and the other end of the electrical connection member is detachably connected with the lamp body; the lamp body is a lamp body integrally formed from an LED light source and an LED driver; and the lamp body is electrically connected with an external power source via the electrical connection member, and a conducting wire I electrically connected with the external power source is placed in the accommodating cavity.

[0008] In the above solution, the lamp cartridge, the electrical connection member and the lamp body are connected in a detachable manner such that the LED luminaire can be quickly and conveniently assembled. Meanwhile, the lamp cartridge is designed such that not only the LED luminaire can be conveniently mounted on a wall or a ceiling, but also the accommodating cavity for accommodating the conducting wire I is also arranged, thus the conducting wire I electrically connected with the external power source is not exposed to improve the safety performance. When the LED luminaire is used, a socket of the external power source also can be covered by the accommodating space of the lamp cartridge to improve the practicability of the LED luminaire such that the LED luminaire and the socket form an integral structure. When the assembly efficiency of the LED luminaire is improved, the overall shape and illumination intensity of the LED luminaire also can be arbitrarily changed by changing the shape and power of the lamp body, the shape of the electrical connection member or the shape of the lamp cartridge, thereby enhancing the versatility of the LED luminaire and the diversity of its shape. Moreover, the detachable connection mode of various components can facilitate the maintenance or replacement of the lamp body and the connection member, thereby reducing the assembly and maintenance cost and improving the working efficiency.
