By using technique scheme, the storage tank energy shadow arranged on lamp door hides light guide plate, diffuser plate, reflecting element, PE Foam and backboard, the degree of depth of storage tank is about the thickness of whole panel light, can transport more convenient with installation process, light LED lamp bead being sent due to the minimizing of thickness can be relatively easy to be irradiated on each light guide member, beats bright whole panel light.

As preferably, described reflecting element is reflective sheeting.

By using technique scheme, due to the lighter in weight of reflective sheeting, cost is relatively low, it is adaptable to large batch of production and convenient installation.

As preferably, described reflective sheeting just one side to PE Foam is provided with sandblasting layer, and the one side back to PE Foam is provided with reflecting layer.

By using technique scheme, reflective sheeting can reduce the consumption of energy, and reflecting layer just to diffuser plate, is used for partly appearing the light line reflection of diffuser plate as bright finish, and the setting of sandblasting layer is avoided that reflective sheeting surface is sent out due to folding and produced folding line on surface, affect reflecting effect.

As preferably, described lamp door is arranged at intervals with multiple first heat sink strip along the short transverse of lateral wall.

By using technique scheme, the heat dispersion arranged in raising panel light sidewall direction of multiple first heat sink strips.

As preferably, the end face of described lamp door is provided with the second heat sink strip that multiple rectangular and territory, face reduces successively.

By using technique scheme, the heat dispersion arranged on raising panel light end face of multiple second heat sink strips.

In sum, this utility model has the advantages that

1, the PE Foam arranged between reflecting element with backboard avoids and relative slip occurs between reflecting element and backboard, improves the lighting effect of panel light；

What 2, diffuser plate both ends of the surface were special arranges diffusion effect and the light transmission improving light；

3, heat dispersion is improved while the convenient installation of the particular design of lamp door.
