Description

A ventilating light guide

technical field

The invention belongs to the field of lighting devices, and in particular relates to a light guide tube capable of exhausting air.

Background technique

The light guide tube is a device that uses a highly reflective light pipe to introduce sunlight from the outdoors into the room, and uses natural light to illuminate the room. It is a green, healthy, environmentally friendly, and energy-free lighting product.

The publication number is CN206131292U, which discloses "a new type of ventilation lighting tube". The "a new type of ventilation and lighting tube" includes the top of the basement, the ground and the fixed wall of the light-conducting ventilation tube, and a plurality of ventilation openings are arranged on the side and bottom of the light-guiding ventilation tube. The wind and air enter the daylighting tube through the vent, and then pass between the daylighting cover and the fixing ring of the daylighting cover, so as to realize the air exchange between the inside and outside of the ventilation lighting tube and improve the air quality in the basement.

However, the above-mentioned "a new type of ventilation lighting tube" still has the following shortcomings:

1. The ventilation effect is poor. The reason is that: through its structure, it can be known that the use of this "a new type of ventilation lighting tube" will make the air in the basement flow through the vent and enter the interior of the lighting tube, and then the lighting The air inside the tube will flow out to the outside (from the gap between the lighting cover and the fixed ring of the lighting cover) under the action of the "chimney effect of the lighting tube". It can be seen that the use of the "a new type of ventilation lighting tube" can only make the air in the basement flow out continuously, which cannot effectively improve the air quality in the basement.

2. Ineffective or poor lighting effect at night, the reason is: the "a new type of ventilation lighting tube" uses natural light directly for lighting, so the lighting effect is directly determined by natural light, and then at night with poor natural light, lighting The effect is naturally very poor, and the use effect is not ideal.

By adopting the above structure, the electric light source installation bin 16 can be quickly plugged into the annular installation groove 142 of the installation cylinder 14 through the plug-in cylinder 161 provided on the outer and lower surface of the electric light source installation bin 16 , thereby realizing the installation of the electric light source installation bin 16 in the installation cylinder 14 . Quick positioning and installation.

Then, by snapping the snap groove 143 of the mounting barrel 14 with a ring of convex rings formed by the inner surface of the lower end of the barrel 1 , the quick assembly between the mounting barrel 14 and the barrel 1 can be quickly realized.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the technical solution. The technical solutions of the above-mentioned modifications and improvements should be regarded as falling into The scope of protection claimed in the claims.
