Embodiment
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
The technical scheme that the present embodiment adopts is: honeybee whirlpool optical collector is comprised of optical collector and the embedded miter angle reverberator that a plurality of (4-12) whirlpool formula helical structure path forms funnel type, access structure is made of the coated reflection material, the miter angle transmitter also adopts the coated reflection material to consist of, and is 45 degree with each path exit portal angle simultaneously.A plurality of identical paths adopt identical angle to form optical collector in the counterclockwise direction.Luminous energy is transferred to luminous energy on the optical collector of honeybee whirlpool by the dome skylight transmission, light is by a plurality of paths of optical collector, adopt the method for reflection, utilize the whirlpool formula helical structure of passage, guarantee that light can only focus on lane exit to luminous energy along path as the principle of black hole, utilize the miter angle principle of reflection to change again optic path luminous energy is transmitted.
In Fig. 1, dome skylight is taked light source and is prevented sealing, dirt; Optical collector profile angle 60 degree are spent into funnel type with ground level normal angle 30.1 is whirlpool formula helical structure path, and 2 is the miter angle reverberator.
In Fig. 2, honeybee whirlpool optical collector is divided into eight identical paths, transmission luminous energy.
Adopt the rotation of turbine structure path to compile to dwindle in each path shown in Figure 3 downwards light is compiled, first surface 3 and the second curved surface 4 are 60 for radian, and are rotated down in the counterclockwise direction the irregular curved surface of 90 degree; The 3rd curved surface 5 is a conical side part; The angle of first surface 3 and the second curved surface 4 is less than 15 degree, and the 3rd curved surface 5 forms a turbine structure path, path from the lighting surface to the outgoing before the path 90-degree rotation compile downwards.The turbine structure path adopts reflectivity more than or equal to 95% plated film minute surface, utilize the reflection of light principle to make light come together in convergence point 6 along path, and light path is for being parallel to ground or angle is very little, utilize miter angle light path principle of reflection so that emergent light is parallel or angle is very little in transmission channel, improve the shooting angle of light, improve the efficient of light in transmission channel.
