Flexible Led lamp net and Led lamp coil

Abstract

The invention relates to a flexible Led lamp net and an Led lamp coil. The flexible Led lamp net comprises a plurality of high-power Led lamps and a radiating net, wherein the high-power Led lamps adopt an SMT (Surface Mount Technology) packaging manner or a COB (Chip On Board) packaging manner; and the radiating net is used for fixing the Led lamps, serves as a radiating body for the Led lamps, is formed by high-density weaving of heat conducting filaments, and is fixed through the manners of welding and gluing. The Led lamp coil comprises the flexible Led lamp net, an upper diffusing plate, a lower diffusing plate and a total reflection plate, wherein the upper diffusing plate is arranged on the light-emitting sides of the Led lamps; the lower diffusing plate is arranged on the backlight sides of the Led lamps; and the total reflection plate is arranged on one side, far away from the Led lamps, of the upper diffusing plate. The Led lamp net, the upper diffusing plate, the lower diffusing plate and the total reflection plate are all flexible and can be tightly stuck mutually and rolled into a coil to be convenient for transportation. The Led lamp net solves the radiating problem of the Led lamps, the Led lamp coil solves the dazzling problem of the Led lamps, and the Led lamp net and the Led lamp coil are low in cost, convenient to mount, and can be used for design of novel lamps and transform of light sources of conventional lamps.

Description

technical field [0001] The invention relates to an Led lamp, in particular to an Led flexible surface light source component. Background technique [0002] Due to its high luminous efficiency and no heavy metals, LED lamps have an obvious tendency to replace incandescent lamps and fluorescent lamps. However, there are three obvious problems in the promotion of LED lamps. The first is heat dissipation. The lifespan of the guarantee period is 100,000 hours (the light decay is less than 30%); the second is the glare problem, because the LED is a point light source, the center brightness is very large, it will be very dazzling when people look directly at it; the third is the installation of the LED lamp, because of the high power Most of the packaging methods of Led are patch (SMT) or core-on-board (COB), which cannot be used directly like light bulbs and lamp tubes.

Problems solved by technology

[0002] Due to its high luminous efficiency and no heavy metals, LED lamps have an obvious tendency to replace incandescent lamps and fluorescent lamps. However, there are three obvious problems in the promotion of LED lamps. The first is heat dissipation. The lifespan of the guarantee period is 100,000 hours (the light decay is less than 30%); the second is the glare problem, because the LED is a point light source, the center brightness is very large, it will be very dazzling when people look directly at it; the third is the installation of the LED lamp, because of the high power Most of the packaging methods of Led are patch (SMT) or core-on-board (COB), which cannot be used directly like light bulbs and lamp tubes.

[0003] In the prior art, a Led surface light source has been proposed. The Led is welded on the aluminum substrate, a heat sink is arranged behind the aluminum substrate, and a light guide plate and an optical anti-reflection film are arranged in front of the Led. The Led surface light source of this structure solves the problem to a certain extent. LED heat dissipation and glare problems, but the lamps are thicker (more than 20 cm), use a lot of metal materials, and the cost is high

There is also a kind of LED surface light source that uses low-power LED lamps (0.1-0.2 watts) to install on the PCB. The light is input from the side of the light guide plate. Diffusion plate, all components are packaged in a metal shell. It is difficult to make a large-area light source for a lamp with this structure, and the lighting range is small. It is generally used in the kitchen

There are still many LED light bulbs and light tubes on the market now, and the existing light bulb and light tube interfaces can be used, which is convenient for installation, but the dense distribution of LEDs makes it difficult to dissipate heat, and the problem of glare is even more difficult to solve

[0004] It can be seen that the above-mentioned existing Led surface light source obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
