The technical principle and the beneficial effects of the utility model are as follows:

the lamp pearl is at the inside light that takes place of lateral wall in illumination chamber, then throws light to the below in illumination chamber through reflector layer and scatter plate, because light is through the reflector layer reflection and have the scattering version to filter, consequently the light of projecting the below can be more even soft, can not dazzling very much. Meanwhile, due to the fact that the heat dissipation channel is arranged, the two ends of the heat dissipation channel are located on the top wall and the side wall of the lift car respectively, the lamp post is fixed on the side wall of the lighting cavity, namely the lamp holder is located on the side wall of the lighting cavity, when the lift car moves up and down, air flow enters and exits from the two ends of the heat dissipation channel, heat of the lamp holder is taken away, and damage to the lamp beads due to heating is avoided.

Through above scheme, ingenious utilization the mode that the elevator reciprocated, with the air current drainage to the lamp stand, and then dispel the heat for the lamp pearl, can effectually dispel the heat for the lamp pearl, prolong the life of lamp pearl.

Preferably, the outer surface of the side wall of the lighting cavity is provided with a plurality of radiating fins distributed along the trend of the radiating channel, the radiating fins are connected with the lamp holder of the lamp bead, and the radiating fins can quickly transfer heat from the lamp holder so as to better take away the heat when airflow passes through the radiating channel.

Preferably, a flow guide shutter with an outer end inclined downwards is arranged at a port of the heat dissipation channel, which is located on the side wall of the car body, and the louver is arranged to better bring airflow into the heat dissipation channel from the side wall when the elevator moves downwards.

Preferably, the inner surface of the top wall of the lighting cavity is an inclined surface with a downward convex middle part, and light rays of the peripheral lamp posts can be better reflected to the lower part through the inclined surface.

Preferably, the middle part in illumination chamber is equipped with the spliced pole, the both ends of spliced pole are connected respectively the top and the bottom in illumination chamber can provide the fixed intensity in diffuser plate middle part through setting up the spliced pole.

Preferably, the connecting column is made of transparent materials, so that the brightness of the contact position of the connecting position and the scattering plate is improved.
