Problems solved by technology

[0002] At present, LED lighting is widely used in various lighting fields. Among the existing LED lighting products, high-power LED lights above 30W, medium-power LED lights between 10W-30W and low-power LED lights below 10W, among which high-power LED lights above 30W and Mid-power LED lamps between 10W-30W have metal or alloy radiators. Although these radiators can reduce the temperature of the light source and improve the power and reliability of the lamps, because metals are conductive and opaque, metal heat dissipation The electrical isolation of the device and the design of the light emission angle lead to large volume, poor safety, small light emission angle, inability to emit light all around, low luminous efficiency, uneven light color distribution, poor designability of appearance, and not wide application environment and scope, etc. ;

[0003] For low-power lighting, filament lamps are mostly used in the market at present. Although it can solve the problem that the current high-power LED lamps cannot emit light all the time, because the current LED filament lamps only rely on inflating the bulb, relying on the gas flow inside the bulb to The heat is transferred to the bulb and then rely on the surface of the glass bulb to dissipate the heat into the air. In this way, the heat conduction is slow and the heat dissipation is poor. There is gas between the LED filament and the glass bulb, the thermal resistance is relatively large, and the reliability is also poor. Therefore, it is difficult to increase the power and increase the luminous flux, so the power of LED filament lamps is basically below 10W. They are mostly used for decorative lighting, and it is difficult to popularize them in the lighting field that requires higher brightness.

If you want to increase the power, you need to increase the filament and glass bulb. There are many problems with the large volume of LED filament lamps. If the glass bulb is too large, the safety will be poor. Large-scale sealing and inflating equipment should be used to seal the lamp. Difficult, low yield, difficult to transport, fragile, and the current LED filament lamp manufacturing process is complex, requiring more production equipment, filament phosphor is not easy to coat evenly, prone to problems and shortcomings such as blue leakage and uneven light output

[0004] Other methods of setting LED illuminants such as LED filaments or LED light sheets on the light-transmitting strips or sheets, because the LED chips are directly fixed to the transparent strips or transparent sheets through the adhesive layer, and then coated or Molded phosphor glue Because the chips, adhesives and phosphor adhesives are exposed in the air, the chips, phosphor adhesives, and adhesives will absorb moisture, quickly oxidize and yellow, leak electricity, swell, peel off and die. Safety and reliability issues such as uneven light output, narrow application range
