Abstract

The invention discloses an LED street lamp superheat protecting method. The method involves providing a lamp body, a heat conducting substrate, an LED bulb on the heat conducting substrate, a power supply equipment and a control circuit. A temperature sensor is provided inside the lamp body of the LED street lamp. The electric current supply is reduced to a proper degree by the control circuit when the temperature of the lamp body reaches a pre-set temperature value, and a normal electric current supply is resumed by the control circuit when the temperature of the lamp body recovers below the pre-set value.

Description

technical field [0001] The invention relates to LED street lamps, in particular to an overheat protection method for LED street lamps. Background technique [0002] The current street lamps mostly use high-pressure sodium lamps, and their lifespan is generally about 5000 hours. LED street lamps have the characteristics of good chromaticity, maintenance-free, and more energy-saving than traditional street lamps. The theoretical life of LED bulbs is generally more than 100,000 hours, which is 20 times that of high-pressure sodium lamps. However, the theoretical service life of LED bulbs is test data within a certain temperature range. When overheating occurs, LED bulbs are prone to sudden damage. Although the industry has made many breakthroughs in heat dissipation materials and lamp body structure, overheating is still inevitable due to the different working occasions of LED street lamps, which actually reduces the service life of LED street lamps.
