Price analysis of radiators for semiconductor lighting
Recently, I went to a company specializing in the production of bulb radiators for LED lighting, and got the company's quotation. The general 3---5W radiator kits have a bulk price (500 sets and above) at 14 yuan. The kit contains : E27 ç¯ lamp holder and connecting plastic parts, two 8cm long wires. A conical radial circular aluminum radiator, a hemispherical sandblasted translucent glass lampshade, and a 42mm diameter aluminum substrate. Retail price: (within a few dozen sets) 16 yuan per set.
Below is a price analysis of the bulb kit:
The spot price of aluminum ingot is currently about 15,200 yuan / ton. The aluminum ingot is made of aluminum alloy 6063 aviation aluminum rod which is made of heat-dissipating aluminum alloy in the profile factory. The ex-factory price is about 23,500 yuan/ton, and the ex-factory price is about 23,500 yuan/ton. The profile is processed and then matched with other accessories to form an LED bulb kit, which is 14 yuan per set. Subdivided parts price: aluminum substrate Ф 42mm piece (1 yuan), E27 mouth lamp head plus plastic connector, 8cm plastic multi-strand connection line two (1 yuan), sandblasted hemisphere milky glass bubble one (1 yuan), aluminum Alloy radiator (11 yuan), after weighing average 65.5 grams per 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: 168,000 - 23,500 = 14,500 / ton, is the price of the aluminum profile of 144,500 / 23,500 = 7.15 times, such a high gross profit is amazing.
The price from aluminum ingots to aluminum alloy profiles increased by 2.35 million/1.52 million = 1.546 times. It can be seen that this price increase is more reasonable.
From aluminum alloy profiles to finished LED radiators, the price increase is 7.15 times of the purchase price. It can be seen that this is not normal. If it is 2-3 times the price increase, it is said in the past, but the price of 7 times is outrageous. Now the price of LED chips has dropped a lot from the previous two years. The price of ultra-high brightness and high-brightness chips for lighting (small size chip 10mil×23mil) is 130 yuan/K, and the chip for 80W bulb LED lamp is 80. Grain × 0.13 yuan / grain = 10.4 yuan, equivalent to the price of aluminum alloy radiator. If the price of aluminum alloy radiators does not fall, the price of LED lamps will remain high. Undoubtedly, LED aluminum alloy radiators are the second roadblocks that hinder the development of LED lighting.
Only by introducing a competitive mechanism can the price of LED aluminum alloy radiator be flattened, otherwise the price of LED lighting fixtures cannot be lowered, and it will also hinder the popularization and use of LED lamps, which is unwilling to see. An industry with too high gross profit is an unhealthy and immature performance of this industry. Only in a reasonable range of gross profit, this industry can develop healthily and sustainably.
At the same time, friends who are interested are also welcome to discuss the price of LED aluminum alloy radiators, analyze the cost of aluminum alloy radiators, make this price more transparent, and also play a supervisory role.
