Intelligently controlled forced convection radiation LED streetlamp system

Abstract

The invention relates to an intelligently controlled forced convection radiation LED streetlamp system, which comprises a lamppost, a lamppost cantilever, a high-power LED streetlamp cap, a radiating fin, a radiating fan and an intelligent drive controller. A radiating substrate of a high-power LED is fixed on the radiating fin; the radiating fan is fixed at one end of the radiating fin; the air intake surface of the radiating fan faces an air outlet of the lamppost cantilever; required airflow enters from air inlets on the upper and lower parts of the hollow lamppost; even if the streetlamp is turned on when the temperature of the substrate of the high-power LED is within a set safety range, the fan does not work and heat is radiated by passive natural convection; and when the temperature of the substrate of the high-power LED exceeds a set safety temperature upper limit 60 DEG C, the fan works and adopts active forced radiation. If the radiating fan fails, excessive dust is accumulated on the air passage and the radiating fin, or the temperature of the LED substrate exceeds a set limit failure temperature 80 DEG C, the circuit of the LED lamp is disconnected, and the controller sends an alarm signal for check and maintenance at the same time.

Description

Technical field: [0001] The invention relates to an LED street lamp, in particular to an intelligently controlled forced convection cooling LED street lamp system. Background technique: [0002] At present, low-power LED lamps are cold light sources and do not require special heat dissipation devices. However, with the increasingly tense energy sources, the use of LEDs as lighting sources has been accepted by people. Low-power LED lamps can no longer meet people's needs. High-power LED light sources It has gradually been developed and applied to the field of lighting, especially in street lighting, which has attracted widespread attention. However, high-power LED lights are different from low-power LED lights. When high-power LEDs emit light, the chip will generate a lot of heat. If the heat cannot be dissipated in time, it will directly affect the luminous efficiency of the LED. According to the test, the high-power LED street light source can work normally when the surface...
