Recently, Shell Wright announced its 2016 financial report. The data showed that the annual operating income was 813 million yuan, up 1.47% over the previous period. The net profit attributable to shareholders of listed companies after deducting non-recurring gains and losses was 34.981 million yuan, a decrease of 29.10% over the previous period. The net cash flow from operating activities was RMB 3,732,200, a decrease of 98.11% from the previous period.

The decline in net profit was mainly due to the continuous increase in the expense ratio and the significant increase in asset impairment losses. The cost increased by 32 million compared with the same period of last year, an increase of 21.31%. As the drone segment continued to increase investment in R&D and market expansion, the expense ratio increased sharply, which affected the profit. At the same time, the asset impairment loss increased by about 11 million compared with the same period of last year. Lead to a decline in profits.

In terms of specific business performance, due to the influence of the development trend of the lighting industry, the fluorescent lamp products on the market have been gradually replaced by LED lamp products, resulting in a decline in sales of fluorescent lamp interior lighting products. The 2016 annual revenue was 77.614 million yuan, a decrease of 36.36% from the previous year.

In 2016, in addition to promoting the old HID car xenon lamp to the market, the company also introduced new LED car lights to the market, and its sales increased significantly. The revenue of the car lighting business in 2016 was 102 million yuan, an increase of 48.53% over the previous year.

Due to the influence of the development trend of the lighting industry, the fluorescent lamp products in the market have been gradually replaced by LED lamp products, and the customer's product orders have also shifted from the original fluorescent lamp products to the LED lamp products. Therefore, the sales of LED indoor lighting series are certain compared with the same period of last year. increase. The LED indoor lighting business revenue was 130 million yuan, an increase of 12.74% over the previous year.

In 2016, the company added the production of charging pile equipment, and the order amount was large, resulting in insufficient production capacity. The company actively adjusted the industrial structure and reduced the output of LED display series products, resulting in a decrease in sales of LED display system series compared with the same period of last year. The LED display system revenue was 88.393 million yuan, a decrease of 31% from the previous year.

Termination of the 472 million yuan additional issuance plan

Recently, Shellett passed the "Proposal on Terminating Non-Public Issuance of Stocks" and agreed to terminate the company's non-public offering of shares. Previously, the total amount of funds to be raised did not exceed 472 million yuan. The funds raised (after deducting the issuance expenses) are intended to be used in the construction and sales service system construction project of the UAV, the construction of the smart street lamp production and sales service system, and the construction project of the LED lighting product marketing system.

Invested 5.1 million yuan to expand overseas markets

In order to integrate the advantageous resources, open up the European and American lighting market, and expand the scale of overseas sales, Xuelaite and Shenzhen Yite Optoelectronics Technology Co., Ltd. (hereinafter referred to as “Yante Optoelectronics”) signed a “Joint Venture Agreement” to jointly establish a joint venture company Shenzhen. City Snowlight Optoelectronics Technology Co., Ltd.

The registered capital of the new company is 10 million yuan, of which Snow Wright invests 5.1 million yuan in cash, accounting for 51% of the registered capital; Yite Optoelectronics contributes 4.9 million yuan in cash, accounting for 49% of the registered capital. The business scope of the joint venture company includes: production, research and development and sales of a full range of dedicated devices for LED small pitch; sales of various lighting products and displays.

Light technology is applied as one of the four major priorities in the future

Recently, at the 2016 annual online performance briefing, the company's chairman Chai Guosheng said that the company is committed to building a high-tech enterprise that is a "light technology application and consumer electronics" industry integration, focusing on "light technology applications" and "smart consumer electronics". , "high-end intelligent manufacturing" and "automobile core components" four areas.


Surge Protection Device SPD

Product Description


SPD Surge Protective Device,Lightning Surge Protector
Surge Protection Device (SPD)

It is a device used to limiting instant surge voltage and discharge surge current, it at least including a non-linear component.

Surge protective Device Model Selection

With the impact of international information flow, the rapid development of microelectronic science and technology, communication, computer and automatic control technology, make the building start to go for high quality, high functional area, formed a new building style-intelligent building. As inside the intelligent building there are lot of information system, <<Building lightning protection design norm>> GB50057-94(2002 vision)(hereafter brief as <<lightning protection norm>>) put forward the relative requirement to install the surge protective device, to ensure the information system safely and stable running.
SPD essentially is a equipotential connection material, its model selection is according to the different lightning protection area, different lightning electromagnetic pulse critical and different equipotential connection position, decide which kind of SPD used in the area, to achieve the equipotential connection with the common earth electrode. Our statement will based on SPD's maximum discharge current Imax, continuous operating voltage Uc, protection voltage Up, alarm mode etc.
As per << Lightning Protection Norm>> item 6.4.4 stipulation "SPD must can withstand the expected lightning current flow and should confirm to the additional two requirements: the maximum clamp voltage during surge across, capable to extinguish the power frequency follow-on current after lightning current across." That is the value of SPD's max. clamp voltage add its induction voltage of two ends should be same with the system's basic insulation level and the equipment allowed max. surge voltage.

SPD for Power Supply System Series Selection Guide

The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity.
The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose.
SPD for power supply system specification selection principle
Max. continuous operating voltage: bigger than protected equipment, the system's max. continuous operating voltage.
TT System: Uc≥1.55Uo (Uo is low voltage system to null line voltage)
TN System: Uc≥1.15Uo
IT System: Uc≥1.15Uo(Uo is low voltage system to line voltage)
Voltage Protection Level: less than the insulation withstand impulse voltage of protected equipment
Rated discharge current: determined as per to the lightning situation of the position installed and lightning protection zone.
