The popularity of led line lights is a problem. At present, the led line lamp is in the development stage and continuously improves the luminous efficiency. However, some technical problems need to be solved to make the led in the field of lighting widely available.

1. Low power. The single led power on the market is generally below 5W, and there is no more powerful led, which is the biggest bottleneck of the current led.

2. Strict control of temperature is required. Led is a semiconductor material, as well as ordinary diode has a p-n junction, due to highlight the power of diode is opposite bigger, so the same as the power semiconductor devices, the need to consider the heat dissipation problem, junction temperature is too high will directly affect the service life of the led, and increases the led light failure, severe cases will led burn out.

3. High price. Besides power is low, the price is led to become an important factor of the main light source, led is now most people know, although also favored by the majority of people, but its high price is difficult to accepted by consumers, currently the yellow led is about 0.6 yuan/a single, single green and blue leds is about 1.8 yuan/a. If you combine a dozen single leds, the cost will increase dramatically. If you put an led in a lawn lamp, the unit price is several times the average lawn lamp. Led to become the mainstream light source of future lighting, it must be developed in the direction of high luminous flux, the cost can be reduced, and the market can break through.

Glow in solid physics, led line lights of luminous efficiency is close to 100%, so the led as lighting source will be following the incandescent lamp, fluorescent lamp, high intensity discharge lamp after the fourth generation of light source, led lamp line will also be widely used.

1. The soft led lamp is made of FPC to assemble the circuit board, which is welded and assembled with the led patch. The thickness of the product is only one 1MM thick, which does not take up space; There are 30 lamps/meters, 48 lamps/meters 60 lamps/meters, etc. Different users have different specifications. And it can be cut at will, can be lengthened arbitrarily and the light will not be affected. The FPC is soft and can be bent, folded and coiled freely, and can be moved and expanded in three dimensions without breaking. Suitable for irregular place and small space use, also because it can any bending and winding, suitable for any combination of patterns in advertising decoration. It is worth mentioning that the FPC itself is also divided into many kinds.

2. The led hard light bar is mainly made of PCB hardboard for assembling circuit board, which needs different, so different components are adopted. The advantages of the hard lamp strip are easy to fix, the heat dissipation is good, and the processing and installation are convenient. The disadvantage is that you can't bend at will, not suitable for irregular places.
