Reflected illumination device based on laser light excitation of fluorescent powder

Abstract

The invention discloses a reflected illumination device based on laser light excitation of fluorescent powder. The reflected illumination device based on laser light excitation of the fluorescent powder comprises a reflector and an emitting device with a laser, the reflector coated with the fluorescent powder is capable of exciting autologous transition by light emitted by the laser so as to emit light different in color, an illumination device comprises a laser light-emitting module adjustable in light spot and a fixing base used for fixing the laser light-emitting module on a building, the laser light-emitting module is rotatably arranged on the fixing base through a middle support mechanism, and a reflecting surface of the reflector is opposite to a light-emitting end of the illumination device and does not contact with the illumination device. The reflected illumination device based on laser light excitation of the fluorescent powder has the advantages of simple structure, convenience in maintenance, capability of meeting illumination needs of different environments and applicability to any place requiring illumination.

Description

technical field [0001] The invention belongs to the field of lighting, and relates to a lighting device for laser-excited fluorescent powder, in particular to a reflective lighting device based on laser-excited fluorescent powder. Background technique [0002] At present, lighting devices are widely used, whether it is corridor lighting in residents' daily life, parking lot, square lighting, or tunnel lighting in transportation, lighting devices are indispensable. With the continuous development of science and technology, lighting devices are also constantly improving. For example, the wide application of LED lamps basically replaces traditional lighting methods because of their advantages of low power, low energy consumption, long life and high brightness. [0003] Although the lighting device has developed rapidly and has the above-mentioned advantages, the existing lighting device basically relies on the light directly emitted by the light emitting device for lighting.

Problems solved by technology

[0004] (1) Inconvenient installation and maintenance: Since the light-emitting part of the existing lighting device is set above the illuminated building, the lighting device is generally installed at a higher position, such as tunnel lighting and residential corridor lighting , are installed on the top of the tunnel and the top of the floor. When the lighting device is installed or the lighting device fails, the maintenance personnel need to use external force to touch the lighting device to carry out the corresponding installation, maintenance and replacement. For the lighting of the residential corridors, it may Maintenance is relatively simple, but it is quite difficult to install and maintain lighting devices in tunnels or public places such as parking lots;

[0005] (2) Poor lighting effect: Since tunnels and parking lot lighting places are relatively empty, from the perspective of cost, the lighting devices installed are limited, so the lighting effect often does not meet the requirements of customers, and if the lighting effect needs to be strengthened, It can only increase the lighting device, which increases the cost and cannot satisfy the requirements of both parties;

[0006] (3) The lighting cannot be adjusted: the existing lighting devices are directly fixed on the top of the building to be illuminated, the brightness and angle of the lighting cannot be adjusted, and the color is single, which cannot meet the lighting needs of various situations
