Accompanying drawing explanation

Fig. 1 is the LED lamp affixed to the ceiling decomposing schematic representation of uniformly light-emitting;

Fig. 2 is the LED lamp affixed to the ceiling profile of uniformly light-emitting;

Fig. 3 is driver fixing LED lamp affixed to the ceiling indirectly;

Fig. 4 is directly fixing LED lamp affixed to the ceiling of driver.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.

Because LED lamp affixed to the ceiling mainly comprises lampshade, chassis, driver and LED lamp plate, do the volume that will certainly increase driver under the prerequisite that large or wish realizes the functions such as intelligent dimming toning at the power of LED lamp affixed to the ceiling, because driver majority is fixed on center chassis position, and LED lamp pearl becomes many group donuts to be evenly arranged on LED lamp plate, due to the cause of driver volume increase, cause the light that is transmitted into lampshade central area near the LED lamp pearl of center chassis position to be absorbed by drive enclosure sidewall, this just causes lampshade non-uniform light and the low result of light fixture optics utilization rate.

In view of the drawback of above-mentioned Design of Luminaires, the utility model adopts driver is arranged on to the LED lamp pearl that do not stop on the chassis surface LED substrate position to emission of light on lampshade, so just avoids being originally transmitted into the light emission of lampshade central area to the situation generation of drive enclosure sidewall.This kind of improvement scheme is the preferred plan that can meet lampshade uniformly light-emitting on the basis that does not increase light fixture cost.

embodiment 1

As depicted in figs. 1 and 2, the LED lamp affixed to the ceiling of uniformly light-emitting comprises installation mounting seat 1 on the wall, be connected to the chassis 2 in mounting seat 1, be arranged on the LED substrate 3 on 2 surfaces, chassis, be arranged on LED substrate 3 optical lens 4 above, 2 central areas, chassis have a groove that can hold driver 5.Lampshade 7 is connected on chassis 2 by lampshade buckle 6, by lampshade 7, LED substrate 3, optical lens 4, driver 5 is covered in to lampshade and chassis 2 engages in the rear space forming.

The groove size that chassis sinks need to guarantee 60 ° of the minimum angle > of LED lamp pearl central point and driver edge point line and vertical direction, so just makes LED lamp pearl major part light all be transmitted into above lampshade.
