[0002] During the construction of a building with an underground garage, a light well is often set up on the roof of the garage to improve the natural lighting effect and ventilation capacity of the garage. Existing underground garage light wells mostly use conventional fiberglass as a protective cover to achieve the purpose of lighting and rain protection.

[0003] The existing underground garage roof often needs to be backfilled to meet the requirements of greening and insulation. Therefore, the upper edge of the existing light well needs to be a certain distance higher than the roof of the basement. The light well is deep and the lighting range is relatively limited. It is bright only directly below the light well. In order to meet the ventilation requirements, the sides of the existing light well protective cover cannot be closed. The existing light well cannot solve the contradictory problem of both closing for insulation and opening for ventilation.

[0050] The specific implementation of this embodiment is as follows:

[0051] During the construction of the garage roof, the light shaft body 1 is constructed and formed simultaneously. After the structure is demolded, the installers install the light guide tubes 2 and the energy-saving hoods 3 on the light shaft body 1. The installers first assemble the light guide tubes 2. After assembling all the light guide tubes 2 in the order of light hoods 21, standard risers 22, bent pipes 23 and diffusers 24 from top to bottom, the light guide tubes 2 are fixed to the inner wall of the light shaft body, and the lower ends of the bent pipes 23 are pointed to various directions around the bottom of the light shaft body 1. The energy-saving hood 3 is then fixed as a whole on the upper wall of the light shaft body 1. After the equipment is installed, it enters the operating state. The light guide tubes 2 collect the light above the light shaft body 1 and transmit it to each diffuser 24, thereby forming multi-directional light diffusion below the light shaft body 1, which significantly improves the lighting range and lighting effect.

[0052] In winter, the kerosene inside the temperature-sensitive expansion tank 331 contracts due to the low temperature, so that the hydraulic sliding rod 3321 slides along the inner wall of the temperature-variable switching tube 332 toward the temperature-sensitive expansion tank 331, so that the air hole 3322 is aligned with the first air outlet pipe 3324, and the light-transmitting photovoltaic panel 321 generates electricity under the sunlight and stores the electricity in the battery 322. The vacuum heat collecting tube 342 generates heat energy exchange under the sunlight, so that the tap water inside it is heated up. The water bodies inside the heat storage tank 341 and the vacuum heat collecting tube 342 realize a cycle in which hot water automatically rises and cold water automatically falls under the action of the thermal cycle, so that the storage The water inside the heat box 341 and the vacuum heat collecting tube 342 heats up as a whole, thereby heating the heating coil 3411. After the electric energy is stored in the battery 322, the ventilator 333 starts to run. The ventilator 333 drives the cold air flow outside the energy-saving cover 3 into the strip air inlet groove 3323, and enters the first air outlet pipe 3324 through the air hole 3322, and then enters the heating coil 3411. The heating coil 3411 heats the air flow to increase the temperature of the air flow. The heated warm air flow is discharged from the hot air pipe 3412 into the garage space below the light shaft body 1, thereby realizing ventilation and purification of the garage air under the premise of heat preservation.

[0053] In summer, the kerosene inside the temperature-sensitive expansion tank 331 expands due to the high temperature, so that the hydraulic sliding rod 3321 slides along the inner wall of the temperature-changing switching tube 332 away from the temperature-sensitive expansion tank 331, so that the air hole 3322 is aligned with the second air outlet pipe 3325, the photovoltaic power generation device 32 continues to generate electricity and store electric energy, the ventilator 333 and the heat dissipation fan 3514 continue to operate, and the ventilator 333 drives the hot air flow outside the energy-saving cover 3 to enter the strip air inlet slot 3323, and enter the second air outlet pipe 3325 through the air hole 3322, and then enter the condensing coil 351 1. The condensing coil 3511 cools down the hot air flow, and the cooled air flow enters the throttle valve 352. The throttle valve 352 cools down the air flow again, thereby significantly reducing the temperature of the air flow. The cold air pipe 3512 transports the cooled air flow to the garage space below the light shaft body 1, thereby achieving ventilation and purification of the garage air under the premise of heat preservation. During this process, the heat dissipation fan 3514 runs and blows on the condensing coil 3511, and the heat inside the condensation heat dissipation box 351 and the heat accumulated inside the double-layer isolation and thermal insulation protective cover 31 are discharged through the heat dissipation pipe 3513.
