According to a person from the quality control department of the main engine factory, because of the high speed of the high-speed rail and the complicated wiring, the technical requirements for the shock resistance of the lamp are relatively high, and the price will be higher than that of the ordinary civilian lamp. The lamp is different.
However, another manufacturer that also supplies high-speed rail is quoted as “half-meter 1000-2000 yuanâ€. According to this calculation, the price of the 1.4-meter long lamp is 2800 yuan-5600 yuan, which is 6669.99. Yuan is still a lot cheaper.
The price of a 12-watt reading light from Hengzhiyuan to CRH2 is 1416 yuan, and the highest price in the market is only 500-600 yuan. Hengzhiyuan explained that the reading lamp is embedded with integrated control of TV frequency modulation, and the special energy-saving control board for reading lamps. The designated suppliers of Sifang must concentrate on purchasing the products of Beijing Yicheng Company, and the cost is as high as 700-800 yuan.
Hengzhiyuan 20W single-tube overhead light is sold at CRH2 for a pre-tax sales price of 2039.01 yuan. The highest specification price of Germany Osram 20W single-tube overhead lamp is about 1,400 yuan.
LED lights for light boxes are used for indicating lighting in rail cars and motor cars, such as toilet instructions and direction indications. Because of their control system, the market price is around 600 yuan, and the same product used on CRH2 reaches 5784 yuan/piece. .
Shenzhen Hengzhiyuan Electric Co., Ltd. (hereinafter referred to as Hengzhiyuan) is located in the third floor of Zhongyi Building, the first industrial zone of Xili Guanlong, Nanshan, Shenzhen. It is difficult to compare it with the China High Speed ​​Rail Project. The main supplier of the cabin lighting is linked.
A Hengzhiyuan executive told reporters that in the current production of high-speed rail CRH380 100 column lighting equipment orders, Xiaoyan Jinchuang got 80 columns, 10 sources of Hengzhiyuan, 10 columns of Zhejiang Lanpu. In addition, most of the lighting products of Shenzhen Metro Lines 2 and 3 are provided by Hengzhiyuan.
Like Wei Han’s Sun Hanben, Xiao Jin’s founder Yu Jinkun is also a supplier that has been publicly praised by Zhang Shuguang. In contrast, the background of Hengzhiyuan is even more mysterious. It is certain that this is a company founded by a number of Shanxi people. Frequently replaced directors and shareholders are also born in Shanxi.
The above-mentioned Hengzhiyuan executives said that more than 50 train compartment lighting products have been delivered, although Xiaoyu Jinchuang Jincheng has a large share, but the auxiliary lighting products are basically provided by Hengzhiyuan. Xiaoyan Jinchuang, and then sold to the Quartet, Xiaoyu Jinchuang from the "earning a certain price difference."
“Xiaoyu Jinchuang has done a good job in the market, but the technology still depends on us.†He revealed that Hengzhiyuan currently owns 65% of the national railway railcar lighting and supplies the North and South vehicles. "We mainly do power and light source, lampshade, and die. We bring together the elites in the industry to serve us."
The reporter saw in Hengzhiyuan that the three-storey factory building of about 3,000 square meters, except for one layer of storage, three-tier office area, has limited space for production and research and development. The head of a department that provides car lighting for high-speed rail is said to be the same as Xiaoyan Jinchuang. The production of Hengzhiyuan products also relies on “outsourcingâ€. The aforementioned Hengzhiyuan executives said that Hengyuan's outsourcing ratio accounted for about 15%, but a staff member of Hengzhiyuan's product research and development department said that 70% of the products were outsourced, and the company mainly assembled. 
Hengzhiyuan is one of the major suppliers of CRH2 lighting equipment. On November 25, 2009, it obtained patents related to flat light source ceiling lamps. According to the senior technical staff in the industry, this patent is a utility model patent and does not involve technological innovation. On the CRH2 purchase order, Hengzhiyuan's LED flat light source dome lamp is priced at 6669.99 yuan and the lamp length is about 1.4 meters. The price of the same type of product Hengzhiyuan to the subway customers is 1,200 yuan.
