Description

  The present invention relates to a streetlight heat dissipation structure using a high power light emitting diode, and more particularly to an improvement made to a streetlight heat dissipation structure.

  A general street lamp is mainly composed of a light bulb, but the disadvantage of the light bulb is that it consumes power and has a short lifetime. High-power light-emitting diodes refer to light-emitting diode products that can normally emit light even when a current of 0.5 watts to 3 watts is applied. Most of these light-emitting diode products are currently light-emitting diode flashlights, high-power light-emitting diodes, and heads. As a backlight light source for LCD screens, there is still room for improvement in terms of luminous efficiency. Therefore, neither upstream crystal particle factories nor downstream package factories have a large shipment volume. Some are still in the experimental research stage.

  After nearly ten years of development, high-power light-emitting diodes are gradually playing an indispensable role in applications in the areas of living, travel, education and music. Due to material properties and packaging technology limitations, light emitting diodes have not yet reached the standard for general lighting lamps in terms of their brightness and service life.

  Among them, the most important cause is that when the light emitting diode package emits light, thermal energy is generated. Therefore, if the heat dissipation design is poor, the brightness and life of the light emitting diode crystal itself decrease at high temperatures, wavelength drift, etc. Invite. Moreover, due to the poor heat dissipation design of current high power light-emitting diode street lamps, the street lamp's breaking speed is accelerated when the street lamps are in a high temperature state.
