Abstract

The invention relates to a split type LED (light emitting diode) streetlamp, comprising an illuminant part which is arranged in a lamp body and serves as a light source. The streetlamp provided by the invention is characterized in that the illuminant part further comprises an LGP (light guide plate) for heat dissipation, a plurality of light plates connected with the LGP and an outer cover sleeved on the light plates and the LGP; and the outer cover and the LGP are respectively connected with the lamp body. Compared with the split type LED streetlamp in the prior art, the split type LED streetlamp provided by the invention has the advantages that the LGP has an angle of 114 degrees, and through the illumination of the LEDs on the two light plates with 90-degree parallel beams, the illumination requirement of the streetlamp can be satisfied; and the illuminant part which can be separated from the lamp body is arranged, so that the light plates and the LGP can be independently disassembled and maintained, thus reducing the maintenance and replacement cost and prolonging the service life of the whole streetlamp.

Description

technical field

[0001] The invention relates to a light-emitting diode street lamp, in particular to a split-type light-emitting diode street lamp. Background technique

[0002] Existing light-emitting diode (LED) street lamps are usually provided with a power supply component to supply power to the light-emitting part, and dissipate heat for it through a lamp body part connected to the light-emitting part. The core component of the light-emitting part is a light-emitting diode (LED) chip, which converts electrical energy into light energy to make the LED street light emit light. At present, in the design and production of LED street lamps, in order to help heat dissipation, several LED chips are usually fixedly connected with the lamp body components directly to form an integral LED street lamp. Although theoretically speaking, the life of LED chips can generally reach tens of thousands of hours, but when one of the LED chips is damaged or an open circuit fault occurs at t...
