Therefore, the underground illumination of the coal mine in China is seen in the development direction of the safety production and energy-saving technology of the coal mine in China, the environment of the underground illumination place of the coal mine in China is severe, complex and changeable, the underground illumination is still one of the bottlenecks which restrict the modernization, automation and intelligent development of the coal mine, and the quality of the illumination equipment is also a direct hidden danger of the safety production. Most of underground coal mines in China are underground mining without natural light sources, the lighting environment needs to be supplied by lighting lamps, and a mine lighting system is an indispensable component of underground production operation of the coal mines. Moreover, the underground illumination of coal mines in China has the characteristics of large area and wide range, and because the total length of the roadway is generally different from 20m to 30km, the roadway is longer or even longer, and the roadway path is complex and has different widths. Because of using the low-efficiency lighting lamp that easily breaks down, in order to guarantee mine workman's operation safety, lighting apparatus installs closely in the tunnel, generally every 20m or so installs a mine light, and the lighting apparatus configuration of main haulage tunnel is mostly fluorescent lamp or white fabric lamp, and the lamps and lanterns specification is mostly 20W, and the fluorescent lamp electric power consumption of a 20W is as shown in figure 1 about 25W. According to data statistics, the annual accumulated illumination time needs more than 8 thousands of hours, compared with industrial enterprises on the ground, the time for illuminating and using electricity under a coal mine is doubled, and the illuminating and using electricity under the coal mine accounts for 8-10% of the total electricity used in the coal mine. The roadway illumination not only has large power consumption, but also has short service life of a light source, small light-emitting area and uneven illumination.
The concept of green lighting was proposed in the early nineties of the last century and rapidly received the recognition of the international society, which was widely spread after the proposal.

In recent years, governments actively guide, promote and build a 'conservation-oriented' society, and 'green, low-carbon, energy-saving and emission-reduction' society increasingly receives attention of the whole society.
Although the problems of short service life, small light emitting area and the like of the traditional light source are solved by the OLED roadway lamp used in recent years, the quality of the light source is influenced by high glare and high blue light of the OLED light source, and the light is dazzling and harmful to human eyes; meanwhile, the problems of complex lamp structure, difficult heat dissipation of the lamp structure and the like are also generated.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The utility model provides a mine roadway lighting device based on an OLED light source as shown in figures 1-3, which comprises an OLED light source 1 and a light source cavity shell 3 and is characterized in that the OLED light source 1 is arranged in the light source cavity shell 3, an OLED heat dissipation plate 4 fixedly connected with the light source cavity shell 3 is arranged above the OLED light source 1, an adhesive explosion-proof surface 5 is arranged at the joint of the light source cavity shell 3 and the OLED light source 1, an explosion-proof junction surface 6 is arranged at the top of the light source cavity shell 3, a cable lead-in nut 7 is arranged in the light source cavity shell 3, a power supply is installed in a built-in manner, a wiring terminal installation position and an input cable fixing mechanism are designed in a power supply cavity, an internal grounding screw L is designed and reserved, and insulating explosion-proof wiring terminals 8 are arranged on two sides in the light source cavity shell 3;

The working principle of the utility model is as follows: the power design adopts 127VAC to exchange wide voltage input, through rectification, filtering and PFC circuit, adopts modern switching power supply technique in principle, and the drive power supply of explosion-proof lamp must have high reliability, and the high efficiency drive has high power factor: the OLED explosion-proof lamp is used for a long time underground, and is difficult to maintain; reliability must be ensured. The high power efficiency and the low power consumption naturally reduce the temperature rise of the lamp. Providing a synchronous assistance to delay the light decay of the OLED light source 1, as shown in fig. 2;
wide range input voltage, the circuit should have surge protection: due to large underground voltage fluctuation, the lamp can normally work within the range of 85-255V; the capability of the OLED light source 1 to withstand surges is relatively poor, in particular to withstand reverse voltages. This aspect of protection is also important in circuit design. Due to frequent start-ups of the grid load and the induction of lightning strikes, various surges from the grid system may be intruded, some of which may lead to damage of the OLED light source 1. Therefore, the OLED light source 1 driving power supply has the capability of inhibiting the invasion of surge and protecting the OLED light source 1 from being damaged. Besides the conventional protection function, the power supply preferably adds the temperature negative feedback of the OLED light source 1 in the constant current output to prevent the temperature of the OLED light source 1 from being too high.
The OLED light source 1 is an "ultra-thin" technology, consisting of several layers of organic molecules that can emit a beam of light when activated by an electrical current. OLEDs are power-saving (mercury-saving) over conventional bulbs or LEDs, are soft, more daylight-like, and can be bent into new shapes. It is a "whole new form of light". And the OLED light source 1 is light and thin surface emitting: the light distribution is uniform and soft, and the thickness of the light source is 1.4 mm.
Meanwhile, the OLED has good light quality, smooth and continuous spectrum, no ultraviolet and infrared radiation, no stroboflash and glare, and high color rendering index (CRI >92 and R9>50), and the evaluation result of the photobiological safety is exemption level (highest level). And the paint is green and environment-friendly, and does not contain toxic and harmful substances such as mercury and the like. Meanwhile, the OLED light source 1 has high energy efficiency, and the energy efficiency of mass production products reaches more than 70 m/W. The OLED light source 1 has a small temperature rise: the temperature is below 30 ℃ at normal lighting (ambient temperature 20 ℃).
At present, the power of the OLED light source 1 is low, so that in order to make a high-power lighting lamp, a plurality of low-power OLED light source 1 chips must be combined in series and parallel to form a flat panel module to achieve the effect of overall surface light emission, and the internal electrical schematic diagram of the OLED light source 1 is shown in fig. 3.
