Description

LED street light

technical field

The utility model belongs to the field of street lamp lighting, in particular to an LED street lamp.

Background technique

In the field of modern lighting, with the research of high-power LED lights, more and more street lights use LEDs as light sources. As a long-life, energy-saving light source, its advantages are self-evident. However, high-power LEDs The price of street lamps is high, and there is one of the biggest problems - heat dissipation is difficult, which brings about a sharp shortening of the LED light decay cycle, resulting in huge economic losses.

Contents of the invention

Aiming at the deficiencies in the prior art, the utility model provides an LED street lamp with good heat dissipation performance.

The utility model is achieved through the following technical solutions:

An LED street lamp, including a lampshade, a bracket, a U-shaped LED module, and a high-brightness LED module, the bracket includes a connecting rod, a fixing piece, and an outer frame, and the fixing piece fixes the connecting rod and the outer frame, The inner side of the outer frame is provided with a base, the lower end of the base is provided with cooling holes and is fixedly connected with a panel, the inner side of the base is embedded with a U-shaped LED module and a reflector, and the reflector is embedded with three sets of bright LEDs module, the back of the bright LED module is provided with a radiator, one side of the radiator is provided with a power controller, the outer side of the radiator is provided with a lampshade, the inner wall of the lampshade is provided with a temperature sensor, and the temperature sensor It is electrically connected with the power controller.

Both the U-shaped LED lamp module and the LED lamp beads of the high-brightness LED module are provided with lenses outside.

The power controller includes a time control switch, a light control switch and a temperature control switch.

The height of the middle cooling fins of the radiator is higher than that of the two sides.

Compared with the prior art, the beneficial effect of the utility model is: the utility model is provided with a U-shaped LED module and a high-brightness LED module, and the U-shaped LED module can provide lighting at night and when the light is bad in bad weather, and the high The bright LED module can be automatically adjusted and selected according to the time control switch and the internal temperature of the lamp cavity. The modular design, sub-regional work and heat dissipation can greatly reduce the pearlescent decay speed of LED lamps, thereby reducing maintenance costs and improving economic benefits.

detailed description

Below in conjunction with accompanying drawing, the utility model will be further described:

Referring to Figures 1 and 2, an LED street lamp includes a lampshade 2, a bracket 3, a U-shaped LED module 4, and a bright LED module 5. The bracket 3 includes a connecting rod 31, a fixing part 32, an outer frame 33, and the fixing part 32. Fix the connecting rod 31 and the outer frame 33. The inner side of the outer frame 33 is provided with a base 9. The lower end of the base 9 is provided with a cooling hole 91 and is fixedly connected to the panel 8. The inner side of the base is embedded with a U-shaped LED module 4 and a reflector 6. The reflector 6 is embedded with three sets of high-brightness LED modules 5. The back of the high-brightness LED module 5 is provided with a radiator 7. A lampshade 2 is arranged on the outer side of the radiator 1 and the radiator 7, and a temperature sensor 11 is arranged on the inner wall of the lampshade 2, and the temperature sensor 11 is electrically connected with the power controller 1.

Lenses are provided outside the LED beads of the U-shaped LED module 4 and the high-brightness LED module 5 to diverge the light source and reduce the impact of glare on the line of sight.

Referring to Fig. 3, the power controller 1 adopted in the utility model includes a light control switch S1, a time control switch S2, and a temperature control switch S3, wherein the light control switch S1 is arranged on the main output line of the power supply. The LED module 4 can be turned on separately, and the time control switch S2 is arranged on the main line of the high-brightness LED module 5. After a preset time, a group of LED lights G1 in the high-brightness LED module 5 remains on. The other two LED lamp groups G2 and LED lamp group G3 work under the control of the temperature control switch S3. When the temperature sensor 11 senses the set temperature, the temperature control switch S3 is used alternately or chooses to turn off the LED lamp group G2 and the LED lamp group. G3.
