Let the light bulb become a wireless router

Due to the serious “upswing” phenomenon in the industry, the LED industry has excess capacity, and fierce competition will also allow the market to welcome an opportunity to quickly reshuffle. In the future, it is expected that more small companies will withdraw from the market. With the development of LED technology, in the future, the industry will no longer only focus on the traditional lighting field, but will develop towards plant lighting and Internet of things technologies.

The three-day 2014 China (Jiangmen) Green Light Exposition closed on the 21st. For the troubled LED industry, what is the current market situation, where is the industrial development goal of Jiangmen, and what new trends will the industry develop in the future?

The reporter learned that due to the industry's “high pull-up phenomenon”, leading to excess capacity in the LED industry, and fierce competition will also allow the market will usher in the opportunity to quickly reshuffle, in the future is expected to have more small businesses out of the market. With the development of LED technology, in the future, the industry will no longer only focus on the traditional lighting field, but will develop towards plant lighting and Internet of things technologies.

Will usher in the "big fish eat fish" game

On October 19, at the "China Lighting Industry Upgrade Summit Forum", famous financial person Ye Tan (blog) said in an address to the LED industry entrepreneurs attending the forum that the LED industry will also usher in the era of mergers and acquisitions, and in the Which grow and develop.

Ye Tan said that the data she has learned shows that there were hundreds of companies in the country that had achieved mergers and acquisitions and reorganizations in the past year, and that the next few years will be a key year for mergers and acquisitions of Chinese companies.

Referring to the LED industry, Ye Tan believes that if companies want to develop, they cannot escape this economic phenomenon. Although there are many LED companies, they will surely usher in a fierce reshuffle. "Little Fish" game, I believe the future LED industry will also leave dozens of companies like Foxconn.

High-tech will be the development trend

In this light exhibition held in Jiangmen, some manufacturers have begun to display the latest cutting-edge technologies in the development of the LED industry, including the future use of LED lighting in plant lighting, and the "Lifi" network in the Internet of Things era.

In addition to the traditional lighting, the LED industry will also transition to new technologies in the future, including plant lighting. According to reports, at present, enterprises in Jiangmen have begun the application of this new technology, and they have begun to use plant lighting to grow rare medicinal materials in Yunnan.

According to reports, the sunlight is a colorful light, but different plants need different wavelengths of light. Many light is wasted, and plant lighting is based on the light waves that different plants most need, and the corresponding light is selected for irradiation to promote its growth. With the breakthrough of technology, plant lighting will be produced in the future and become a new development trend of LED lighting.

The "Lifi" network is another new area in the LED industry. "Lifi", also known as visible light communication, utilizes LED bulb lighting to transmit information. As long as the light is shining, there are Lifi signals for free Internet access. Lifi is the same as WiFi, but it is more convenient and faster than WiFi. As long as there are LED bulbs, it is equivalent to a router sending information.

During the mid 1970s, researchers developed a maintenance-free lead-acid Battery that can operate in any position. The liquid electrolyte is gelled into moistened separators and the enclosure is sealed. Safety valves allow venting during charge, discharge and atmospheric pressure changes.

 Driven by different market needs, two lead-acid systems emerged: The small sealed lead-acid (SLA), also known under the brand name of Gelcell, and the larger Valve-regulated-lead-acid (VRLA). Both batteries are similar. Engineers may argue that the word 'sealed lead-acid' is a misnomer because no rechargeable battery can be totally sealed.

 Unlike the flooded lead-acid battery, both SLA and VRLA are designed with a low over-voltage potential to prohibit the battery from reaching its gas-generating potential during charge because excess charging would cause gassing and water depletion. Consequently, these batteries can never be charged to their full potential. To reduce dry-out, sealed lead-acid batteries use lead-calcium instead of the lead-antimony.

 The optimum operating temperature for the lead-acid battery is 25°C (77°F). Elevated temperature reduces longevity. As a guideline, every 8°C (15°F) rise in temperature cuts the battery life in half. A VRLA, which would last for 10 years at 25°C (77°F), would only be good for 5 years if operated at 33°C (92°F). The same battery would desist after 2½ years if kept at a constant desert temperature of 41°C (106°F).

 The sealed lead-acid battery is rated at a 5-hour (0.2) and 20-hour (0.05C) discharge. Longer discharge times produce higher capacity readings because of lower losses. The lead-acid performs well on high load currents.
