However, with its efforts in the domestic market, its domestic sales reached 279 million yuan in 2017, accounting for 28.31%, an increase of 4 percentage points compared to last year. Contrary to Golden Wright, Ocean King is based on domestic sales. According to its annual report, Ocean Wang's domestic sales reached 1.051 billion yuan, accounting for 95.84% of total revenue; overseas sales were 406 million yuan, accounting for 4.16%.

For the future development of mobile lighting, the three listed companies have expressed optimism. Jin Laite said that the industry development of rechargeable emergency products will tend to pursue miniaturization and integration, and the downstream applications of products will become more extensive and product functions will become more diversified. The company will continue to explore the development, production and sales of rechargeable backup lighting and related products. Ocean King shows that although the competition in the special environmental lighting industry is becoming increasingly fierce, the company is also facing many new development opportunities. For example, the reform of state-owned enterprises will release many reform dividends, and the construction of the maritime powers and the strategy of the Belt and Road will drive fixed assets. The substantial increase in investment, the 13th Five-Year Plan, China Manufacturing 2025, and the Energy Development Action Plan 2016-2020 will bring opportunities to the company. Kang Mingsheng also bluntly said that the company will seize the market opportunities brought about by the transformation and upgrading of LED lighting consumption, continue to focus on the main business of LED mobile lighting products, take market demand as the guide, take technological innovation as the driving force, take brand management as the core, and do well Products, improve efficiency, optimize the diversified layout and output of sales channels, strengthen the investment and construction of e-commerce and overseas channels while strengthening and deepening the advantages of the company's distribution channels, and comprehensively enhance the company's operational quality and sustainable development capabilities. In summary, with the continuous improvement of the LED market penetration rate and the guidance of relevant national strategies, the prospects of the mobile lighting market are generally optimistic.
