LED red and blue plant lights use the ratio of red and blue lamp beads, mainly because a single LED chip cannot maturely "integrate" light of different bands on the same chip. Since 2013, LED chips and packaging processes have become more and more mature, and full-spectrum LED plant growth lamps have begun to appear on the market, but the market’s response has been tepid, due to expensive lamp costs, electricity costs and crop yields. The proportion and the limited level of my country's agricultural modernization development, LED plant growth lights are less acceptable in China, and the use of LED plant lights abroad is also mostly used in modern vertical farms for vegetable and fruit planting.

The turning point appears from 2018 to 2020. The industrial hemp market is gradually liberalized in North America, and some other countries will also put on the agenda whether to liberalize industrial hemp cultivation. Industrial hemp, such as high economic value-added crops, "gives" plant growth lights. With the new life, industrial hemp planting lights have become hot, and many domestic lighting companies have entered the market.

TPO company is the FIuence company acquired by Osram. Through repeated experiments and comparisons, it came up with the most effective lamp bead ratio for cannabis cultivation-Osram's red (660nm) and Samsung's high-efficiency white (301B). Gradually, such a spectrum scheme is accepted in the market, and the general lighting company that enters the market thinks that the use of such a scheme is a cannabis lamp. Is this actually the case?

The information gap, slow response, and the undeniable gap between Chinese companies and the top technology. The extension and chip are not meticulous enough, the research investment is insufficient, and the research on targeted programs is lacking. Due to such and other problems, even Weizhao The first batch of companies that developed and produced plant lights in mainland China did not slow down, and now they can only work hard to catch up with the plans of Osram and Samsung.

Is it that we really can't make good plant growth lights?
