The vacuum packaging machine uses plastic or plastic aluminum foil film as a packaging material to vacuum liquid, solid, powdery paste food, grain, fruit, pickles, preserves, chemicals, medicinal materials, electronic components, precision instruments, rare metals, etc. Packaging, vacuum-packed items can prevent oxidation, mildew, insects, decay, moisture, and extend the shelf life. It is especially suitable for tea, food, medicine, shops, research institutions and other industries. It has the advantages of beautiful appearance, compact structure, high efficiency, easy operation, seat wheel at the bottom, convenient movement and so on.

Domestically, it is expected that in the next three to five years, with the development of upstream chips, the proportion of indoor lighting products occupying 40 semiconductor lighting applications is very optimistic.
First, the LED application product heat dissipation structure design accounts for about 20 in the lamps and lanterns. The Chinese industrious people have always been very low in price. The 20 cost is considered very reasonable. The biggest problem is how to be more innovative and more reasonable in design.
The cost of heat dissipation should be maintained at 5, the actual heat dissipation design is very simple, and the two directions are kept: First, the shorter the path between the LED chip and the external heat sink, the shorter the heat dissipation design is. The second is the heat dissipation resistance. It is necessary to have enough heat to pass to the path and also have enough heat dissipation roads. This part of the cost is mainly in the structure, and the cost for heat dissipation is not much.
Second, LED application power weak power supply is the weakest link of led lamps, serious delay led lamps development, quality needs to be improved. Now the design accounts for about 20 of the cost of the lamp, and some are high. With the development of technology, the power supply is probably at 5-10.
The high cost of LEDs is actually compared with other current light sources. As the LED industry that invented blue LEDs in the 1990s, which led to the realization of LED white light, the current cost is not high. In particular, LED is environmentally friendly, energy efficient, and contains no mercury. Moreover, the price of LED lamps is declining every quarter. It is believed that it will reach a level acceptable to people in a short period of time.
Third, domestic enterprises have no core technology. Most of the core patents in the upstream of the LED industry are in the hands of foreigners. We do not master the core technology, even though our LED application product manufacturing capacity accounts for 50% of the world, the share accounts for 50, but the profit. It is indeed the lowest link.
LED chips adopt a larger size wafer manufacturing process with the increase of process and quantity, which will continuously reduce the cost. In recent years, the speed of 20 is reduced every year, and the price factor of LED chip is also included in the price reduction. Buy a better product at the same price. The cost of LED lighting is mainly in the LED chip. As long as the price of the chip is lowered, the lumen price of the LED can be reduced to the equivalent of the current energy-saving lamp, and the indoor lighting will naturally bloom everywhere. LED chips also have a lot of room for price cuts.
Domestically, it is expected that in the next three to five years, with the development of upstream chips, the proportion of indoor lighting products occupying 40 semiconductor lighting applications is very optimistic.
