A solar lighting device

Abstract

The invention discloses a solar illumination device which comprises a natural light collecting device. The top of the natural light collecting device is provided with an automatic cleaning device, a solar battery plate base recombiner is connected with the lower portion of the natural light collecting device in a buckled and sealed mode and is provided with multiple solar luminosity sensors, a reflection grating assembly is arranged on the inner wall of the solar battery plate base recombiner in a buckled mode, the lower end of the reflection grating assembly is fixedly provided with a light guide tube, a dimming device is arranged in the light guide tube, the dimming device is provided with a storage battery and a solar intelligent controller on the outer wall of the light guide tube, the storage battery is connected with a photovoltaic power generation assembly and the solar intelligent controller in the solar battery plate base recombiner through wires, the bottom end of the light guide tube is connected with a solar illumination device base, the bottom of the base is connected with a diffuser, and the base is provided with an LED illumination lamp set provided with an LED radiator in a matched mode. A natural light source is used for lighting and illumination during the day, photovoltaic power is combined with the LED lamp set for illumination at night, and accordingly the illumination requirements of use areas in a building are met.

Description

technical field [0001] The invention relates to a device for architectural lighting, in particular to a green, low-consumption and environment-friendly solar lighting device. Background technique [0002] At present, indoor lighting is generally provided with windows in the building, and external sunlight is introduced into the room through the windows. For buildings that are relatively closed and cannot be directly illuminated, lighting fixtures are generally used for indoor lighting. During the use of lighting lamps, it not only wastes electric energy, but also has potential safety hazards, especially for some processing workshops, shopping malls, underground garages and other environments. In addition, electric lighting can only provide lighting with a single wavelength, while the emission spectrum of sunlight has a wider band, and lighting with sunlight makes people feel more comfortable. [0003] In order to introduce sunlight into buildings that cannot be directly ill...

Problems solved by technology

[0008] In summary, this type of device has the following problems: first, the lighting device only has a lighting surface in one direction, and the lighting efficiency is low; Effective collection, light concentration, and non-concentrated refraction; third, the hemispherical roof is in the open environment for a long time, and in the absence of manual cleaning, the collection efficiency of natural light caused by floating dust or dirt decreases; fourth, there is no optical sensor , can not accurately perceive light lighting to turn on and off the indoor LED light group; fifth, the LED light group is in the light guide tube, which is not conducive to the heat dissipation of the LED light group and the effective supplementary light effect, and it is easy to communicate with the light guide in the daylighting cover. The inner wall of the light tube condenses into water vapor or dew, which makes maintenance inconvenient
