"In our company, outdoor lighting products are the focus. In order to open up a bigger market, continuous development of new products is the direction of the company's efforts." Ms. Yan, the person in charge of Sanma Electric, told reporters that the LED emergency lights exhibited this time and LED floodlights are the company's new products.
It is understood that Sanma Electric has deep technical advantages in the optical design of led lighting, the structure of lamps, and the research and development of LED driving power. Sanma Electric has a number of invention and utility model patents, the main products include LED bulbs, fluorescent lamps, panel lights, street lamps and so on.
The appearance of the LED emergency light looks like a beautiful flashlight, and it doesn't have much appeal. But as soon as the flashlight is turned on, it contains a mystery. The flashlight can be used to adjust the color of the light, and the brightness of the light is also variable. The key is that the screw of the lamp can be removed, and the screw is equivalent to the bulb of the E27 screw, which can be replaced with each other. In addition, the power consumption of the lamp is 3w, which is very energy efficient. 
The LED floodlight can be composed of three lamps of 10w according to the customer's needs. It can adjust the light in various colors and has a long service life. At present, the products are mostly used in outdoor industrial and mining production.
It is reported that Sanma Electric's high-life LED high-power street light benefits from its other two independent inventions: high-life aluminum electrolytic capacitors and high-life drive power supplies.
In LED high-power street lamp products, more than 90% of the faults come from power supply equipment, and 90% of the faults of the power supply are subject to the existence of electrolyte in the electrolytic capacitor. Once the electrolyte is reduced or dried, its capacitance will change or even Complete failure, and traditional electrolytic capacitors are unlikely to solve this problem. 
As far as the power supply is concerned, the traditional LED street lamp generally uses the switching power supply as the driving power source. In principle, its power factor and efficiency are relatively high, but the switching power supply has its own weakness: the system reliability is difficult to guarantee. It consists of hundreds of electronic components. As long as one component has a problem, the whole system will not work properly, causing the LED street light to flash or go out (especially the LED street light, its working environment is poor, and the switching power supply is extremely vulnerable.
The LED drive power developed by Sanma Electric has bypassed the R&D routine of traditional switching power supply. It is simple, sturdy and durable. It is suitable for long-term work in harsh environments and can ensure that it is not bad for more than 10 years.
