Abstract

The utility model relates to a lighting device which is mainly composed of a lighting structure and a base, wherein the lighting structure is a hemispherical honeycomb-shaped structure composed of lighting channels which are evenly distributed from the spherical surface to the spherical center. The lighting channel is a funnel-shaped regular polyhedron channel. The outer part of the lighting channel expands, and the inner part of the lighting channel retracts. The inner wall of the channel is a reflection wall surface. The concourse position of an inner opening of the lighting channel is connected with a cone-shaped general spotlight funnel, a lower opening of which is connected with transmission optical fibers. A lighting structure is fixed to the base. The hemispherical honeycomb lighting device has the advantages of long lighting time of all day lighting from sun rise to sun fall and no requirement of a tracking device. The utility model has the advantages of energy saving, simple structure, firmness, durability, small volume, low manufacture cost, easy installation, beautiful and elegant appearance, independent or combined utilization and high safety.

Description

A kind of lighting device

Technical field

The utility model relates to a kind of lighting device, particularly a kind of sunlight collecting device.

Background technology

Sunlight collecting device technology generally adopts parabolic reflector and autotracker in conjunction with coming daylighting at present, and complex structure, power consumption, cost height are difficult to promote, and are out of order easily, and often the someone goes to safeguard, and is very inconvenient.

The utility model content

The utility model purpose is to provide a kind of simple in structure, practical lighting device.

To achieve these goals, the utility model adopts following technical scheme: lighting device mainly is made up of lighting structure and base, the hemispherical alveolate texture that lighting structure is made up of daylighting passage equally distributed, from the sphere to the centre of sphere, the daylighting passage is the infundibulate regular polygon passage of receiving in extending out, the daylighting passage internal orifice place of converging is connected with total optically focused funnel of a taper, total optically focused funnel end opening is connected with Transmission Fibers, and lighting structure is fixed on the base.

Also extend between the internal orifice place of converging of described daylighting passage and the total optically focused funnel and be provided with a little optically focused funnel that coaxial inside and outside wall is all reflective.

Described regular polygon passage is the regular hexahedron passage.

Described lighting device outside also is provided with the printing opacity dust cover.

Described dust cover and lighting structure are fixed on the supporting plate, and pallet is fixed on the base by carriage, seal with glass cement between dust cover and the supporting plate.

Adopted this hemispherical honeycomb lighting device that advantage is once arranged: the daylighting time is long, can be from sun to sun before whole day daylighting; Do not need extra tracking means and relevant power-driven system, saved the energy, and simple in structure, firm and durable; Volume is little, and cost is low, and is easy for installation, gracefulness handsome in appearance; Can be used alone or in combination, safe.

The specific embodiment

Embodiment: the lighting device shown in Fig. 1-4 mainly is made up of lighting structure 2 and base, the hemispherical alveolate texture that lighting structure 2 is made up of daylighting path 10 equally distributed, from the sphere to the centre of sphere, the daylighting path 10 is the infundibulate regular polygon path 10 of receiving in extending out, the path 10 inwall is reflective wall, the daylighting path 10 internal orifice place of converging is connected with total optically focused funnel 3 of a taper, and total optically focused funnel 3 end openings are connected with Transmission Fibers 8.

Also extend between the end opening place of converging of daylighting path 10 and the total optically focused funnel 3 and be provided with a little optically focused funnel 9 that coaxial inside and outside wall is all reflective, effect be when the angle on incident ray and ground hour, prevent that light is reflected away because of injecting near level.For keeping the cleaning of lighting device, make hemispheric dust cover 1 with glass or plastics that printing opacity is good, be arranged on the lighting device outside.

Dust cover 1 and lighting structure 2 are fixed on the supporting plate 4, and pallet 4 is fixed on the base 6 by carriage 5, seal with glass cement between dust cover 1 and the supporting plate 4.Connect with bolt between supporting plate 4, carriage 5 and the base 6.Connect with nut between total optically focused funnel 3 and the optical fiber 8.

Supporting plate 4 centers are provided with groove, and dust cover 1 is buckled on the supporting plate 4, with the enclosed slot between glass cement closed dust cover 1 and the supporting plate 4, total optically focused funnel 3 is put in the groove at supporting plate 4 centers, be fixed on nut 7 and take off on the plate 4, supporting plate 4 is fixed on the carriage 5, and carriage is fixed on the base 6.Optical fiber 8 one ends are connected total optically focused funnel 3 end openings, and the other end is connected the place that needs light source.

Sunshine passes the daylighting path 10 that dust cover 1 enters cellular lighting structure 2, and light enters total optically focused funnel 3 through repeatedly reflecting to converge, and by the optical fiber 8 that total optically focused funnel 3 end openings connect, the polymerization sunshine is delivered to the place that needs light source.The hemispherical alveolate texture that cellular lighting structure 2 is made up of daylighting path 10 equally distributed, from the sphere to the centre of sphere, daylighting path 10 are the infundibulate regular polygon passage that collar extension 12 expands, internal orifice 11 is received.

The daylighting path 10 can be the regular hexahedron passage, also can be regular polygon passages such as positive trihedral passage, positive tetrahedron passage; The hemispherical dome structure of lighting structure 2 can be positive hemispherical; it also can be semielliptical shape; can also be the part of ball and by chance be not ball half etc.; these similar variations all are equal to mutually with the technical solution of the utility model; all fall in the protection domain of the present utility model; for example abundant for morning and evening daylighting, lighting structure can adopt semielliptical shape, and the major semiaxis North and South direction of ellipsoid, semi-minor axis east-west direction are provided with.

This lighting device can be used alone or in combination, because it is simple in structure, volume is little, cost is low, flexible, the daylighting time long and do not need electric energy to drag, can be widely used in hotel, exhibit halls, especially can be used for the place of tunnel, some inflammable and explosive equal altitudes safety requirements of mine.
