Problems solved by technology

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 the connection point, it is inconvenient to disassemble and repair the light-emitting components, and the entire street lamp can only be replaced, which increases maintenance cost

Embodiment Construction

[0022] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0023] The split-type LED street lamp provided by the present invention includes a light-emitting part arranged in the lamp body 40 and powered by a power source. The light emitting part includes a light guide plate 20 , two light plates 10 fixed on the light guide plate 20 , and an outer cover 30 sleeved on the light guide plate 10 and the light guide plate 20 .

[0024] See figure 1 As shown, the light board 10 is provided with 30 light-emitting chips 111, which are the light sources of street lamps. Every 10 light-emitting chips 111 are connected in series to form a chipset 11, and three chipsets 11 are arranged in parallel. The above-mentioned light-emitting chip 111 is an LED (light-emitting diode) chip with 90° optical focus, so it can form a 90° parallel light beam perpendicular to the surface of the light plate 10 . Several first connecti...

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...
