Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] An LED street lamp includes a lamp body 1, an LED light source 2, a power supply unit 3, a control circuit 4, and a circuit board 5. A temperature sensor 6 is installed in the lamp body, and the temperature sensor 6, the control circuit 4 and the power supply unit 3 are connected in series. The LED light source 2 is installed on the circuit board 5, and the control circuit is fixedly connected to the lamp body.

[0013] The lamp body of the LED street lamp includes an upper casing 8 and a lower casing 9, both of which are made of aluminum. The lower casing has a concave reflector 10, and the LED light source 2 is installed in the reflector 10. The design of the reflector 10 can enhance the light-gathering effect of the LED street lamp.

[0014] A cooling fan 7 is installed in the LED street lamp to be connected with the temperature sensor 6 . When the temperature s...

Abstract

The invention discloses an LED (Light Emitting Diode) street lamp which comprises a lamp body, an LED light source, a power supply device, a control circuit and a circuit board, wherein the lamp body is internally provided with a temperature sensor, and the temperature sensor, the control circuit and the power supply device are connected in series. The LED street lamp is internally provided with the temperature sensor and a heat radiating fan, thus the temperature of the ELD light source in the street lamp can be timely and intelligently controlled and reduced, which is helpful to reduce the light attenuation of the LED light source; and meanwhile, the shell of the LED street lamp is made of aluminum material, thus the weight of the street lamp is reduced, and the heat radiating effect is better. The invention has the advantages that the LED street lamp is convenient to mount, the temperature of the street lamp can be effectively controlled, and the service life of the LED street lamp is prolonged.

Description

technical field [0001] The invention relates to an outdoor lighting device, in particular to an energy-saving street lamp device with the function of adjusting the internal temperature. Background technique [0002] Existing outdoor street lamps often have problems such as short service life and high maintenance rate due to high internal temperature during long-term use. On the one hand, it is due to the technical bottleneck of the heat dissipation of the LED itself, and on the other hand, due to the fact that the outdoor street lamps are turned on for a long time, the street lamps lack an early warning device for intelligent temperature control. Therefore, it is necessary to make corresponding improvements to the internal devices of the street lamp in order to prolong its service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an LED street lamp with a temperature protection device in view of the shortene...
