Recently went to a company specializing in the production of LED lighting bulb radiator company, got the company's quotation, generally 3 --- 5W radiator kit bulk price (500 sets and above) at 14 yuan, the kit contains : E27 mouth lamp holder and connecting plastic parts, two 8cm long wires. A conical radial radiator with a radial shape, a semispherical semi-transparent glass shade, and a 42mm diameter aluminum base plate. Retail price: (within dozens of sets) RMB 16 per set.
The following is a price analysis of the bulb kit:
The current spot price of aluminum ingots is approximately RMB 15,200/ton. Aluminum ingots are made of aluminum alloy 6063 aviation aluminum rods that are made of alloy materials added to the profile plant. The molds are used to extrude heat-dissipating profiles. The ex-factory price is about 23,500 yuan/ton. After the profile is processed and matched with other accessories, it becomes a LED bulb kit, and each set costs 14 yuan. Subdivided parts price: Aluminium substrate Ф 42mm (1 yuan), E27 mouth lamp holder plus plastic connector one, 8cm plastic stranded cable two (1 yuan), sandblasted hemisphere milky glass bubble one (1 yuan), aluminum Alloy radiator (11 yuan), weighing an average of 65.5 grams each aluminum alloy radiator, the price per gram of aluminum alloy radiator is 11 yuan / 65.5 grams = 0.168 yuan / gram, that is 168 yuan / kg, 168,000 / Ton.
The gross profit of the aluminum alloy radiator is: 168,000 - 23,500 = 14,500/ton, which is 145,500/23,500 = 7.15 times the price of aluminum. Such a high gross profit is amazing.
The price from aluminum ingots to aluminum alloy profiles increased by 23,500/15,200 = 1,546 times. It can be seen that this price increase is reasonable.
From the aluminum alloy profiles to the finished LED radiator price increase is 7.15 times the price of the material, it is obvious that this is not normal, if it is 2-3 times the price increase in the past, but more than 7 times the price is outrageous. Now the price of LED chips has fallen a lot compared to the previous two years. The price of ultra-high brightness and high brightness chips for illumination (small size chips: 10 mil x 23 mil) is 130 yuan/K, and 5 watt bulb LED lamp chips are used. Grain × 0.13 yuan / grain = 10.4 yuan, and aluminum alloy radiator price is quite. If the price of aluminum alloy radiators does not drop, LED lighting prices will remain high, no doubt LED aluminum radiator is the second obstacle to the development of LED lighting.
Only by introducing a competition mechanism can the prices of LED aluminum alloy radiators be reduced, otherwise the prices of LED lighting fixtures cannot be reduced, which will also hinder the popularization and use of LED lamps. This is something that we do not want to see. A gross profit margin of an industry is an unhealthy and immature performance of the industry. Only the gross margin is in a reasonable range, and the industry can develop in a healthy and long-term manner.
At the same time also welcome friends who are interested to explore the price of LED aluminum alloy radiator, analyze the cost of aluminum alloy radiator, make this price more transparent, but also can play a supervisory role.
