As shown in fig. 1, in example 1, an integrated device for air purification and illumination of an elevator based on an excimer light source is provided, which comprises an excimer light source module and an illumination device which are arranged on a ceiling 1 of a car of the elevator, wherein in example 1, the number of the excimer light source modules is 1, the excimer light source module is arranged in the middle of the ceiling 1, and the illumination devices 4 are four, and the excimer light source module is arranged on the ceiling 1 and positioned around the excimer light source module.

As shown in fig. 2, 3 and 4, in the present embodiment 1, the excimer light source assembly includes a mounting box 2 mounted on the ceiling 1, and an excimer light source 3 is mounted in the mounting box 2.

As shown in fig. 2 and 3, in the present embodiment 1, the entire excimer light source module is located outside the car and mounted on the ceiling. The mounting box 2 comprises a mounting frame 5 and a housing 6 on the mounting frame 5, as shown in fig. 4, two opposite sides of the housing 6 are provided with mounting holes 18 for mounting the excimer light source 3, and the excimer light source 3 is disposed on the housing 6 through the mounting holes.

A plate type filter cover 7 is arranged between the installation frame 5 and the ceiling 1, corresponding through holes 9 are arranged on the plate type filter cover 7, the installation frame 5 and the ceiling 1, and bolts 14 pass through the through holes 9 to install the installation frame 5 and the plate type filter cover 7 on the ceiling 1 together.

In this embodiment 1, the excimer light source 3 includes a tubular electrode 15 and a rod-shaped electrode 16 inserted into the tubular electrode 15, krypton chloride gas is provided in the space of the tubular electrode 15, as shown in fig. 4, 3 pairs of opposite mounting bearing holes 18 are provided on the outer cover 6, so that 3 excimer light sources 3 are mounted, a power line through hole 17 is further provided on the outer cover 6, and a driving power supply lead of the excimer light source 3 is introduced into the mounting box through the power line through hole 17 and connected to two electrodes of the excimer light source 3.

In practical application, the number of the pairs of the mounting bearing holes 18 formed in the outer cover 6 can be determined according to the size of the elevator space and the number of the required excimer light sources, the number of the mounting bearing holes is not limited by the number of the excimer light sources, and the number of the mounting bearing holes is selected by a person skilled in the art according to the appropriate disinfection irradiation energy of the car area.

In this embodiment 1, the excimer light source 3 is driven by a Dielectric Barrier Discharge (DBD) mode, which is an unbalanced gas Discharge with an insulating Dielectric inserted into a Discharge space, and is also called a Dielectric Barrier corona Discharge or a silent Discharge. The dielectric barrier discharge can work in a high air pressure and a wide frequency range, and the common working air pressure is 10-10000. The power supply frequency may be from 50Hz to 1 MHz.

Dielectric barrier discharge is usually driven by an Alternating Current (AC) high voltage power supply of a sinusoidal waveform (sinusoidal), and as the supply voltage increases, the state of the reaction gas in the system undergoes three-stage changes, i.e., breakdown gradually occurs from an insulating state to a discharging state. When the supplied voltage is relatively low, although some gases may have some ionization and free diffusion, the current is too small because of too small a content, and is insufficient to cause plasma reaction of the gases in the reaction region, and the current is zero. However, when the voltage applied to the reaction gas is not high enough to provide sufficient energy for the electrons to undergo inelastic collisions, the number of electrons cannot be increased so much as a result of the lack of inelastic collisions, and therefore the reaction gas remains in an insulating state and discharge cannot occur, and the current at this time slightly increases but is almost zero as the voltage applied to the electrodes increases. If the supply voltage is further increased, when the electric field between the two electrodes is large enough to cause inelastic collisions of gas molecules, the gas will increase greatly due to the inelastic collisions of ionization, and when the electron density in space is higher than a critical value and Paschen breakdown voltage, many microdischarges (microdischarges) are conducted between the two electrodes, and at the same time, the phenomenon of luminescence (luminescence) is observed in the system, and the current will increase rapidly with the increase of the applied voltage.

In dielectric barrier discharge, when the breakdown voltage exceeds the Paschen breakdown voltage, a large number of randomly distributed microdischarges occur in the gap, and the discharges are uniform, diffuse and stable as long as the air gap between the electrodes is uniform. The microdischarges are composed of a plurality of fast pulsed current filaments, each of which is randomly distributed in discharge space and time, and the discharge channel is substantially cylindrical, each of which is a microdischarge that spreads as a surface discharge on the surface of the medium and appears as a bright spot. These macroscopic features will vary with the power, frequency and medium applied between the electrodes. If a dual dielectric is used and sufficient power is applied, the corona discharge will exhibit a "filamentless," uniform blue discharge that appears like a glow discharge but is not a glow discharge. This macroscopic effect can be observed directly in the experiment through the transparent electrodes or the air gap between the electrodes.

As shown in fig. 4, the central portion of the ceiling 1 is provided with a hole 8, the hole 8 is used for embedding a protruding portion of the plate-type filter mask 7, and the plate-type filter mask 7 is used for adjusting light color and eliminating glare and is generally made of transparent material.
