Problems solved by technology

Since the heat generated by the LED light-emitting diode is relatively high during use, and the LED bulb can only dissipate heat through radiation during use, the heat dissipation efficiency is low, and it is easy to cause the LED bulb to be damaged due to excessive temperature during use, and Existing LED luminous brightness is not high enough to meet the existing needs, even if the brightness is improved, it still needs to consume more energy

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a novel LED light bulb using gallium nitride LED chips. Background technique [0002] LED light-emitting diodes have been used more and more frequently in the field of lighting because of their advantages such as long life, high luminous efficiency, no radiation, and low power consumption. LED bulbs use LED light-emitting diodes as light sources and use incandescent lamp shells. Bulbs are mainly used in common indoor lighting, and the LED bulbs in the prior art include an interface, a bulb, and a plurality of LED light-emitting diodes. Since the heat generated by the LED light-emitting diode is relatively high during use, and the LED bulb can only dissipate heat through radiation during use, the heat dissipation efficiency is low, and it is easy to cause the LED bulb to be damaged due to excessive temperature during use, and Existing LED luminous brightness is not high enough to me...
