Problems solved by technology

[0003] Under the existing technology, LED has been used as a lighting source, and in-line LEDs are generally used. In-line LEDs need to be installed on a larger-sized circuit board during its production process, but the larger the size of the circuit board, the larger the size of the circuit board. The more difficult it is to manufacture, the higher the cost; in addition, the simple splicing and design make the internal structure of the lighting products made of in-line LEDs unreasonable, and it has been unable to solve the problem of light decay. The brightness of LEDs was very bright when they were first used. , After using it for a period of time, it began to darken. The important reason for the light decay is that the in-line type is packaged with resin, and the heat insulation is not good, which leads to poor heat dissipation when the LED emits light, resulting in excessive aging and damage to the internal components; LED As a new generation of lighting sources, lighting products using LEDs should also have good appearance and performance, and LED lighting devices made of in-line LEDs and the aforementioned methods will gradually be eliminated

The invention solves problems in the prior art and provides an LED lighting device with the advantages of good heat radiating performance and flexible structure.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device using an LED as a light source. Background technique [0002] Compared with traditional light sources, LEDs (Light Emitting Diodes) have high luminous efficiency, energy saving, small size, mercury-free solid state, and environmental protection; in addition, LEDs do not need starters and ballasts to light up, fast start, no flicker, It is not easy to look tired; the service life of the LED light source with excellent performance is also several times longer than that of the traditional light source, which can reach 50,000 to 80,000 hours; it is one of the key development products of the national green energy-saving lighting project, so LED has become a substitute for existing fluorescent lamps, energy-saving The main product of traditional lighting sources such as lamps. [0003] Under the existing technology, LED has been used as a lighting source, and in-line LE...
