A kind of LED lamp affixed to the ceiling that changes light emitting region
Technical field
The utility model relates to a kind of LED lamp, relates in particular to a kind of LED lamp affixed to the ceiling that changes light emitting region.
Background technology
Along with the development of technology, the LED solid light source is used increasingly extensive, and it is also more and more as lighting source.Because the requirement of optically focused when LED itself has the limitation of beam angle and Lighting Design, the range of exposures of existing LED lamp affixed to the ceiling is all fixed, and can't adjust its light direction, and is inconvenient when installing and use.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of LED lamp affixed to the ceiling of changed light emitting region of easy to install, capable of regulating starting direction is provided.
The technical scheme that the utility model adopts is: the utility model comprises framework and at least one LED luminescence unit, described LED luminescence unit comprises the light source board assembly with several LED, be positioned at the radiator at the described light source board assembly back side, the described LED lamp affixed to the ceiling that changes light emitting region also comprises ball-end part, ball-and-socket spare, the ball-and-socket fixture, the afterbody of described ball-end part and described radiator are fixedly connected, the head of described ball-end part is that bulb and the ball-and-socket that is positioned at described ball-and-socket spare are connected with the ball-and-socket phase universal rotational of described ball-and-socket spare, and described ball-and-socket fixture and described ball-and-socket spare are fixedly connected and are clamped and fastened on the described framework.
Described LED luminescence unit also comprises the lens module that is positioned at described light source board assembly bright dipping the place ahead.
Described LED luminescence unit also comprises dull and stereotyped transmission element, with periphery and the seal cover that gets up of described light source board component sealing of described dull and stereotyped transmission element.
Described lens module comprises the suitable lens of quantity and position of several and described LED.
The afterbody of described ball-end part and described radiator are fixedly connected by screw thread, and described ball-and-socket fixture and described ball-and-socket spare are fixedly connected by screw thread.
The described LED lamp affixed to the ceiling that changes light emitting region comprises at least two LED luminescence units, the described LED lamp affixed to the ceiling that changes light emitting region also comprises mounting plate, described mounting plate is fixed in terrace by at least two screw class securing members, described mounting plate is fixedly connected with a bolt, and described bolt passes described framework and a hold-down nut fixes that described framework is fixed.
Described mounting plate is provided with at least one slotted hole that is used for passing described screw class securing member.
The beneficial effects of the utility model are: because afterbody and the described radiator of ball-end part described in the utility model are fixedly connected, the head of described ball-end part is that bulb and the ball-and-socket that is positioned at described ball-and-socket spare are connected with the ball-and-socket phase universal rotational of described ball-and-socket spare, described ball-and-socket fixture and described ball-and-socket spare are fixedly connected and are clamped and fastened on the described framework, head by described ball-end part is that bulb and the ball-and-socket that is positioned at described ball-and-socket spare are connected with the ball-and-socket phase universal rotational of described ball-and-socket spare, but so that the described radiator and the described light source board assembly universal rotational that are fixedly connected with described ball-end part, thereby be easy to install and adjust light direction, therefore the utility model is easy to install, the capable of regulating starting direction can change light emitting region.

The specific embodiment
Such as Fig. 1~shown in Figure 3, the LED lamp affixed to the ceiling of the changed light emitting region of the present embodiment comprises this framework 1, mounting plate 10, and four LED luminescence units, each described LED luminescence unit comprises the light source board assembly 2 with several LED, be positioned at the lens module 3 in described light source board assembly 2 bright dipping the place aheads, be positioned at the radiator 4 at described light source board assembly 2 back sides, ball-end part 5, ball-and-socket spare 6, ball-and-socket fixture 7, dull and stereotyped transmission element 8, periphery and the seal cover 9 that seals of described light source board assembly 2 with described dull and stereotyped transmission element 8, the afterbody of described ball-end part 5 and described radiator 4 are fixedly connected by screw thread, the head of described ball-end part 5 is that bulb and the ball-and-socket that is positioned at described ball-and-socket spare 6 are connected with the ball-and-socket phase universal rotational of described ball-and-socket spare 6, described ball-and-socket fixture 7 is fixedly connected by screw thread with described ball-and-socket spare 6 and is clamped and fastened on the described framework 1, described lens module 3 comprises the suitable lens of quantity and position of several and described LED, by described lens module 3, light-configuration mode with LED in narrow space changes optically focused into by floodlight, realized the variation of lamp luminescence mode, the user demand of the different occasions that are content with very little, can realize spotlighting, have multiple illumination and decorative effect, described mounting plate 10 is fixed in terrace by two screw class securing members 11, described mounting plate 10 is fixedly connected with a bolt 12, described bolt 12 passes described framework 1 and a hold-down nut 13 fixes that described framework 1 is fixed, described mounting plate 10 is provided with a slotted hole 15 that is used for passing described screw class securing member 11, so that adjust described mounting plate 10 is installed.
Certainly, the quantity of described LED luminescence unit is minimum can be one, realizes changing too the effect of light emitting region, and above embodiment is the usefulness for illustrating only, is not the restriction to the utility model protection domain.
The utility model is that bulb and the ball-and-socket that is positioned at described ball-and-socket spare 6 are connected with the ball-and-socket phase universal rotational of described ball-and-socket spare 6 by the head of described ball-end part 5, but so that the described radiator 4 and described light source board assembly 2 universal rotationals that are fixedly connected with described ball-end part 5, thereby be easy to install and adjust light direction, therefore the utility model is easy to install, the capable of regulating starting direction can change light emitting region.
The utility model can be widely used in the LED lighting field.
