E-cig as a substitute of tobacco mainly reminds people of its potential benefits for health. Four ingredients contain in the e-liquid : propylene glycol, glycerin vegetable, nicotine and food grade essence. Nevertheless, smoke from cigarette contains carbon monoxide, tar, arsenic, ammonia, and many other cyanide and acetone.

Liquid immersion heat management package solves problems of light decay, heat dissipation and light type
Since LED lighting is most afraid of light decay, it will enter a state where the luminous efficiency becomes weak after using for a period of time. The degree of decline varies from product to product, but the key is also related to the heat dissipation of the LED. If the heat dissipation is not good, The more serious the LED light decay, the faster it will happen. Jiang said that through the heat-dissipation technology of liquid and metal film, the heat generated by the LED light will pass the heat to the metal through the heat-dissipating film. The metal is a material that can be easily heated and heated, and can quickly turn the LED. The heat is transferred out of the chip, and when the metal sheet hits the liquid, it continues to conduct heat to the liquid. The characteristic of the liquid is that heating is not easy. To give a lot of heat, the temperature will rise by one degree, and the heat will spread out. The liquid in the bulb will convect and the heat will be evenly transmitted, so the combination of the two has a complementary effect.
As for the luminous efficiency, the cooling and heat dissipation design of the special liquid, together with the high refractive index factor of the liquid, can reduce the internal reflection of the LED light, so that the overall light extraction efficiency of the LED bulb can reach 70% or more, and the sustainable progress In the middle, 50~55% LED lamps are better than the square. The light type is also a medium-sized medium. The light type is more uniform. In addition to the wide light design, it can also design a narrow-angle light type, which creates more applications.
According to Jiang Zong, the company has cooperated with manufacturers to develop a new AC LED street light scheme. It can arrange 40~100 4W AC LED bulbs to create AC LED streetlights. The light from each other will not be flooded and will not spread between each other. Cooling, and independent power supply lights up. If the AC LED bulb is replaced by a solid fault, there is no need to go back and forth to the factory for maintenance like a conventional LED street lamp, so that the maintenance cost and the replacement cost are greatly reduced.
Have obtained safety regulations and multi-national patents, and look forward to the popularization of LED lighting at a reasonable price to help global energy conservation
As for the LED bulbs that are asked to contain special liquids, whether the weight can be applied to the commonly used lamp holders, Mr. Jiang pointed out that the energy-saving lamp or the general bulb E26/E27 can bear the weight specification of up to 2 kg, currently the company 4W The AC LED bulb weighs 95 grams, and the 2W AC LED bulb weighs 65 grams, so it definitely meets the market specifications. When you want to do more power, the weight of the LED bulb will still be controlled within the specifications. No problem.
In the application of AC LED bulbs that require heat dissipation and must expand the illumination angle, the "liquid immersion heat management solution" safety certification is relatively possible, and it has successfully obtained UL/CUL and other national safety certifications. He summed up several advantages of this series of AC LED bulbs, including the cost of heat dissipation, the risk of electric shock, safety certification, the closest to traditional incandescent bulbs, automated mass production, and good weather resistance. Dust-capable, and has a long-term anti-aging glass bulb material, just like a normal daylight bulb, even after one or two decades of storage, it can still be lit.
He also stressed that the company has developed a number of related technologies, including the structure of the heat sink, the special formulation of the liquid, the special packaging technology, the special process of the LED bulb, etc., and has applied for more than 8 industrial countries. The patent rights are confident in the future global AC LED lighting market.
At present, liquid-state solid-state lighting has been cooperating and contacting with many companies. It is expected that more practical and reasonably priced AC LED lamps can be implemented in daily households, and AC LEDs cannot be made into noble energy-saving lighting products. A more prosperous and cheaper way to make it popular in thousands of towns.
