The net profit attributable to owners of the parent company was 12,228.36. Ten thousand yuan, a loss of 6,551,700 in the same period last year, an increase of 1962.60%.

According to the announcement, during the reporting period, the company's main business income increased significantly compared with the same period of last year, which was caused by the newly added PV power plant EPC project revenue and photovoltaic power generation business revenue after Huayuan New Energy consolidated. The increase in these incomes is the main reason driving income changes. Huayuan New Energy achieved a net profit of RMB 137,102,100 in the first half of the year.

Since the completion of Huayuan New Energy's acquisition in August last year, the company's main business involves “photovoltaic, lighting, photovoltaic + lighting” business, and PV is mainly EPC business and photovoltaic power generation business of solar photovoltaic power station; “Lighting, The photovoltaic + lighting aspect is mainly the research and development, production and sales of traditional solar photovoltaic lighting products, high-efficiency LED light sources, solar consumer electronic products and the provision of various LED lighting sources.

In addition, during the reporting period, LED lighting revenue also increased compared with the same period of last year. The company optimized the existing LED business, highlighted the advantageous business, and strengthened the steadily improved LED lawn lamp business and LED lighting business in the North American market.

Main business composition:


Ultrasonic Sensor

Yuhai Company is engaged to research and development of piezoelectric products and related piezoelectric products, the related piezoelectric products includes the piezo sensors and transducer.


The ultrasonic transducer is a kind of transducer that converts the ultrasonic signal into electric signal, or vice versa. Ultrasound transmitter and receiver is a transducer that can transmit and receive ultrasound. Ultrasound sensor is a kind of sensor, in essence, it is also a transmitter and receiver. The working principle of this kind of equipment is similar to that of radar and sonar. Active ultrasonic sensors can emit and receive reflected waves, and determine the distance of the target by measuring the time interval between transmission and reception. Passive ultrasonic sensor is actually a microphone that can convert ultrasonic signal into electrical signal.

According to the working principle and materials used, the ultrasonic transducer has piezoelectric transducer, electrostatic transducer (capacitive transducer), magnetostrictive transducer, electromagnetic acoustic transducer, mechanical transducer and other types [1].
