Abstract
Description
- This lighting device relates to the field of lighting technology and intended for utilizing as light-emitting diode lighting equipment easily adaptable and suitable for outdoor operation.
- It is known that modular makeup devices are featured with a number of benefits. Particularly, with this kind of embodiment applied, it is possible to shorten the period of designing, reduce production costs and simplify operating and upgrading functions ("Polytechnic Dictionary" under the editorship of A.Yu. Ishlinskiy, Moscow, "Soviet Encyclopedia", 1989, p. 311)
- A number of solutions describing the modular structure of lighting devices including the first lighting module equipped with emitting sources, which end section is fitted with attachment for mating the end section of the second lighting module, which is also fitted with attachment for mating the end section of the third module, which is also designed for attaching the following module, are currently in use (patent
US2006050505 issued on 09.03.2010, IPC F21S4/00; patentEP 1433997 issued on 30.06.2004 , IPC F21S4/00). - The CYC-2-50 (70) outdoor LED lighting fixture containing two LED modules spaced at the angle of 50 (70)º is currently in use (http://www.energonovo.ru/production/led.teh/s.u.o.3.h tm). No information concerning the method of LED module inter-mating is provided, but one thing is clear enough that the both units are fixed on a supporting pole.
- The LED modular lighting device containing a base module fixed on the supporting pole and fitted with attaching means for connecting an additional mating module and designed as a rotating pair that runs around its axis, is currently in use. The mating module is also fitted with similar elements connected to the following module. The axes of all serially connected modules lie in vertical plain passing through the axis of a support. The known solution makes it possible to adapt close alignment of the lighting device modules by means of combining fixing elements with module connecting elements. But due to integration of specific module holders and fixing elements, the module connecting elements have rather complicated design. Thus, the time spent on lighting fixture assembly and maintenance is extended and product costs goes up (patent
KR 101027101 (B1 - As applied by both the functionality and design, Patent
KR 101027101 - The claimed solution causes to diversification of outdoor-adaptable LED lighting devices and allows simplifying their modification. Since the lighting fixtures may be thoroughly mated less fixing elements, their assembly and maintenance time, as well as production costs may be reduced.
- The claimed solution may be characterized by the features as follows:
- The lighting device containing a basic LED module designed for fixing on a separate supporting pole and, at least, one mating LED module and housing attachment, characterized by the extrusion-molded housing to have internal and external radial surfaces and for the interconnection element designed as a sliding pair, where the first sliding pair link is produced on the surface of the fixed module housing and the second sliding pair link - on the surface of the mating module housing.
- Optionally, the lighting device may be completed with two mating LED modules fixed symmetrically relative to the basic LED module.
- If enhanced, the lighting device may be additionally completed with short-length LED modules.
- The sliding pair link contours may be molded and shaped along with the housings under extrusion and integrated both inside the body, and on the body surface.
- The module housings have specific sliding radial surfaces suitable for connection of angular-configured modules.
- The lighting device is explained by the following drawings:
- The lighting device perspective drawing is given in
Fig.1 ; - Cross-sectional view of the fixed lighting device LED module case, as specified by
Fig. 1 , is given inFig. 2 ; - Cross-sectional view of the lighting device mating LED module case, as specified by
Fig. 1 , is given inFig. 3 . - The lighting device contains
base LED module 1, fixed on aseparate pole 2 and comprisesemitting sources 3 integrated inhousing 4 with itsradial surface 9.Mating module 6 comprisesemitting sources 7 andhousing 8 with itsradial surface 9. Connection element ofhousings link 10 integrated inbasic module housing 10 and withlink 11 integrated inhousing 8 ofmating module 6. - Originally,
link 10 is designed as a tee-slot made onhousing 4 ofbasic module 1. In this case,link 11 is designed as a lug made onhousing 9 ofmating module 8. To mate lighting device modules, it is necessary to slide a lug ofhousing 8 inside the tee-slot ofhousing 4 till the mating housings are fully aligned relative to each other. - When mating the lighting device LED modules, no additional fixing elements are required, but reliable alignment and positioning is provided. This kind of a modular lighting fixture is simple in operation and service.
- The required configurations of the modular lighting fixture are obtained due to employment of specific molded housing shape. In addition to, the flat light-emitting surface may face both outwards and inwards.
- The alternative designs of the elements described may be optionally extended. Some equivalent structural solutions may have various embodiments adaptable in scope of specific applications. The embodiment components have production-friendly shape and may be duly employed along with a number of known automatic control facilities.
