The led light bar is assembled by PCB hard board and low-power led light bead patch. Generally, 72 light beads or 60 light beads are evenly arranged within one meter. This material generally consists of aluminum substrate and glass brazing plate. The aluminum substrate is characterized by rapid heat dissipation. Under normal circumstances, the lamp beads will not appear large light attenuation and lamp death because of high temperature. Generally, the thicker the aluminum substrate of the light bar, the better the overall heat dissipation effect of the light bar. The disadvantage of aluminum substrate is that improper cutting of aluminum substrate can easily lead to short circuit. Shenzhen Feideli Lighting Technology Co., Ltd. has developed the fourth generation of spliced led light bars to solve this problem. It is a complete light bar with different lengths, and terminals are welded at both ends, so it can be freely spliced and assembled without secondary cutting and welding in the showcase factory, thus avoiding slight short circuit caused by virtual welding.

The carrier of led soft light bar is FPC board, which is assembled by patch led beads. Small and slim, 3M glue is used for installation, and there are terminal wires at both ends. It is a multi-purpose horizontal flexible light bar. Soft glossy products are generally the thickness of a coin, while conventional and hard glossy products are 60 beads and 72 beads per meter.

Another material of led hard light bar is glass brazing plate, not metal material, which can avoid short circuit, but the heat dissipation effect is poor. Lighting the light bar for a long time will lead to the phenomenon that the headlights are not lit because of the high temperature. The installation of hard light bar needs aluminum groove for installation and fixation. There are conventional gold, silver and aluminum tanks in the market. The aluminum tanks independently developed by our company are gold, silver, rose gold, champagne gold and black light, which can meet the needs of various occasions and decoration styles. Hard light bars are widely used in jewelry counters, mobile phone cabinets, cosmetics cabinets, clocks, shoe cabinets and light display cabinets, and are mostly used in display cabinet factories and jewelry companies.

An important point that distinguishes the soft light bar from the hard light bar is that it is flexible and can be freely placed in three-dimensional space to achieve the modeling effect, for example, it can be placed in advertising lights and pasted into various shapes. LED soft light strips can be cut short between units according to the trial length, and are mostly used in showcase factories, mobile phone counters, advertising light boxes, ceiling decoration, car modification, cabinet lights, wardrobe lights and night garden lighting.

The core technology of LED light bar is the life-span light decay of light beads and the overall heat dissipation of light bar. Compared with traditional fluorescent lamps, incandescent lamps and metal halide lamps, LED light strips are more energy-saving, better in heat dissipation and longer in service life.
