Street light fitting with luminous diode heat radiating device

Abstract

The invention relates to a street lamp which is provided with a LED heat radiator, an outdoor illuminating device applied to streets or public squares. The street lamp comprises a lamp box; an illuminating window is arranged on the lower body of the lamp box; a transparent lamp house is mounted on the illuminating window; the lower box body is connected with an upper box body; an arched framework with a vaulted cross-section is arranged at the lower box body; a plurality of luminescent modules are mounted on the lower surface of the arched framework, and radiating members are mounted on the upper surface of the arched framework. The luminescent LED of the luminescent module is connected with a rapid radiating metal-base printed circuit board in a heat-conducting manner. The invention adopts a rapid radiating metal-base printed circuit board; the structure and material ensure that heat produced during the operation of the LED can be transmitted to the heat radiator rapidly and efficiently. The invention also includes a series of heat radiating members made of solid conducting mediums with sound heat-conducting performance which can transmit the heat directly into outdoor air; and the solid medium can protect the electric apparatus inside the lamp box from being eroded by winds, rains and dusts.

Description

technical field [0001] The invention relates to a street light fixture with a light-emitting diode cooling device, which is a lighting device for outdoor lighting of roads or squares, is a lighting device that combines a plurality of light-emitting diodes into a light source, and is a lighting device for lighting Diodes can effectively dissipate heat from street lights under the premise of waterproof and dustproof. Background technique [0002] Using light-emitting diodes as the lighting light of street lamps will become the mainstream of street lighting sources. How to solve the heat dissipation problem of high-power light-emitting diodes in use is the key to popularizing light-emitting diode street lights. Chinese patent "High Power LED Street Lamp)" (application number: 200710044400.2, application date July 31, 2007) proposes a high-power light-emitting diode street lamp.

Problems solved by technology

Chinese patent "High Power LED Street Lamp)" (application number: 200710044400.2, application date July 31, 2007) proposes a high-power light-emitting diode street lamp. Although the patent has noticed the problem of heat dissipation, there is no special structural solution This problem is simply a description of the use of heat sinks for heat dissipation

Therefore, it is one of the reasons why the prior art light-emitting diode street lamps cannot be popularized not only to dissipate heat but also to prevent dust and water.
