Abstract

The utility model relates to a lighting device which is composed of a frame, a plane fixed mirror, a movable mirror, etc. The lighting device is fixed under the outer part of a window of a building for reflecting outdoor rays into a room, so the sufficient light irradiation is obtained in the room. The angle and the intensity of the reflected rays into the room can be changed by adjusting a reflecting angle of the movable mirror.

Description

Lighting device

The utility model what lighting for buildings.

Residential housing at present develops to high stratification, and the spacing between the Lou Yulou also heals and becomes intensive, the floor natural daylight illumination trend that tapers off from top to bottom.Stay in below the building which floor user, though the window daylighting area that is provided with by construction standards is arranged since around the blocking of building, often feel the illumination deficiency, the daytime illumination of still need turning on light, this not only wastes electric power, has also increased user's spending.

The purpose of this utility model is with a simple device, under the condition that does not change building structure, increases the natural daylight flux in the inlet chamber.

This device profile is as a drawer, and base plate has an aperture so that leak.The one side is below the window of bolt installation what house, and it is outdoor to expose what.Above the device is mirror, uses the what reflection ray; Mirror is made up of two parts, and a part is fixed, is called fixed mirror, and another part is movable, can adjust reflection angle, is called flexible mirror.Outdoor light is through the reflection of mirror, in the window inlet chamber by building.

Be described further with accompanying drawing below

The cutaway view of Fig. 1 device, (dotted line is depicted as flexible mirror change angle)

The vertical view of Fig. 2 device,

The cutaway view that Fig. 3 device is fixed below window,

1 framework, 2 preceding fixed mirrors, 3,4 flexible mirrors, 5 steady pins, 6 parallel-crank mechanisms, 7 back fixed mirrors, 8 bolts, 9 base plates among the figure.

The oblique drawer of framework (1) shape picture, its rear portion is with bolt (8) fixedly below the what building window, preceding fixed mirror (2) and back fixed mirror (7) be the top of what framework (1) fixedly, there is flexible mirror (3) at the position therebetween. and (4), (3). (4) connect on the galianconism of what parallel-crank mechanism (6), galianconism can be around fixedly steady pin (5) swing of what framework (1), between the long-armed and galianconism of parallel-crank mechanism (6) is hinged, when parallel-crank mechanism (6) when steady pin (5) is swung, flexible mirror (3). (4) are both swings thereupon also, and pendulum angle is consistent.The light of outdoor scattering is through the reflection of the fixed mirror and the flexible mirror of this device, and the window that sees through building is injected on indoor ceiling and the wall.

This apparatus structure is simple, and cost of manufacture is cheap, and the light of entering the room through reflection is through the scattering of ceiling, and light is soft, the illumination abundance.

Claims (1)

1. A kind of lighting device, by framework (1), fixed mirror (2). (7), flexible mirror (3). (4), etc. form, it is characterized in that, install below the what building window, flexible mirror (3). (4) can make flexible mirror (3) by parallel-crank mechanism (6) around steady pin (5) swing. (4) interlock.
