The utility model provides a technical scheme that its technical problem adopted is:

The utility model provides a polycarbonate lighting lamp shade subassembly, is in including luminescent light source and cover the polycarbonate light-passing board of luminescent light source bottom surface, luminescent light source include the aluminum product base plate with set up in a plurality of LED luminescence chip of aluminum product base plate bottom surface, be provided with on the polycarbonate light-passing board with a plurality of the protruding bubble of a plurality of LED luminescence chip position one-to-one, every protruding bubble live one with it position correspondence the LED luminescence chip.

As a further improvement of the technical scheme, the edge of the bottom surface of the aluminum substrate is also provided with an LED light source driver, and the edge of the polycarbonate light-transmitting plate is provided with a driving placing groove for covering the LED light source driver.

As a further improvement of the technical scheme, the bottom surface of the polycarbonate light-transmitting plate is also provided with wavy grains.

As a further improvement of the above technical solution, the LED lamp further comprises a lamp cap base and a polycarbonate light-transmitting cover, wherein the polycarbonate light-transmitting cover is buckled on the bottom surface of the lamp cap base, and the light-emitting light source and the polycarbonate light-transmitting plate are arranged between the lamp cap base and the polycarbonate light-transmitting cover.

As a further improvement of the technical scheme, an n-shaped flanging is arranged at the edge of the polycarbonate light-transmitting cover, and a light-transmitting cover installation groove matched with the n-shaped flanging is arranged on the bottom surface of the lamp holder base.

compared with the prior art, the beneficial effects of the utility model are that:

The utility model provides a polycarbonate lighting lampshade assembly, the protruding bubble of polycarbonate light-passing board has the light scattering effect, and makes the scattered light of a plurality of LED luminescence chips superpose each other, thereby can improve the distribution uniformity of street lamp holder illumination light, makes the illumination scope increase, and avoids the light dazzling; in addition, compared with the traditional glass lampshade, the polycarbonate lampshade is not easy to break, so that the lamp holder base can be detachably and fixedly connected by bolts, the light source is convenient to replace when the light source is damaged, the whole street lamp holder does not need to be replaced, and the use cost of the street lamp holder is reduced; just the utility model provides a polycarbonate light-passing board has great heat radiating surface area, therefore the thermal diffusivity also can satisfy the operation requirement of LED light source.

Detailed Description

Referring to fig. 1 to 3, fig. 1 to 3 are schematic structural views of an embodiment of the present invention.

As shown in fig. 1 to 3, a polycarbonate lighting lampshade assembly comprises a light-emitting source and a polycarbonate light-transmitting plate 1 covered on the bottom surface of the light-emitting source, wherein the light-emitting source comprises an aluminum substrate 2 and a plurality of LED light-emitting chips 3 arranged on the bottom surface of the aluminum substrate 2, the polycarbonate light-transmitting plate 1 is provided with a plurality of protruding bubbles 4 corresponding to the positions of the LED light-emitting chips 3 one by one, and each protruding bubble 4 covers one LED light-emitting chip 3 corresponding to the position of the protruding bubble. Specifically, the edge of the bottom surface of the aluminum substrate 2 is further provided with an LED light source driver 5, and the edge of the polycarbonate light-transmitting plate 1 is provided with a driving placing groove 6 covering the LED light source driver 5. The bottom surface of the polycarbonate light-transmitting plate 1 is also provided with wavy grains 11.

The light rays emitted by the LED light-emitting chips 3 are scattered by the convex bubbles 4 in the positions corresponding to one another and then are superposed with one another, so that the light rays penetrating through the polycarbonate light-transmitting plate 1 are uniform and soft, the light rays are not dazzling, and the illumination range is large; in addition, the polycarbonate light-transmitting plate 1 has a large heat dissipation surface area, so that the heat dissipation performance is good.
