Abstract

The utility model relates to an intelligent LED street lamp which comprises a lamp post and a lamp fixed onto the lamp post. The lamp is provided with a PCB (printed circuit board) substrate, an LED lamp is mounted on the PCB substrate, a temperature sensor is fixedly mounted in the lamp post, the PCB substrate is provided with an LED control circuit, and the temperature sensor and the LED lamp are electrically connected with the LED control circuit. The temperature sensor is used for detecting environment temperature, and the LED control circuit controls lighting colors of the LED street lamp according to variation of the environment temperature to indicate environment temperature variation. The LED street lamp gives out warm-color lights in cold season to enable people to feel comfortable and gives out cool-color lights in hot season to enable people to feel cool, so that the intelligent LED street lamp is more humanized and intelligent. Further, the service life of the LED street lamp can be doubled, and the intelligent LED street lamp can be applied widely.

Description

A kind of intelligent LED street lamp

Technical field

The utility model relates to a kind of LED light fixture, is specifically related to a kind of intelligent LED street lamp.

Background technology

Street lamp is the important component part of city illumination, and traditional street lamp often adopts high-pressure mercury lamp, and high-pressure mercury lamp 360 degree are luminous, and the shortcoming that light loss is big has caused the huge waste of the energy.Current, global environment is going from bad to worse, and each state is all at the development clean energy resource.And along with the rapid growth of national economy, China's energy supply and demand contradiction is outstanding day by day, the coming into existence situation of critical shortage of supply of electric power, and energy-conservation is present institute urgent problem.Therefore, development of new is efficient, energy-conservation, the life-span is long, colour rendering index is high, the LED street lamp of environmental protection has a crucial meaning to city illumination is energy-conservation.Existing LED street lamp glow color is generally fixing monochromatic light, its function singleness, not enough hommization and intellectuality.

The utility model content

To the deficiency of prior art, the utility model provides a kind of street lamp to change color with the variation of environment temperature, has hommization and intelligentized LED street lamp.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of intelligent LED street lamp; Comprise lamppost, be fixed on the light fixture on the lamppost; Said light fixture is provided with the PCB substrate, on the said PCB substrate LED lamp is installed, and is installed with temperature sensor in the said lamppost; The PCB substrate is provided with a LED control circuit, and said temperature sensor and LED lamp electrically connect with the LED control circuit respectively.

As improvement, said LED lamp comprises cool colour LED lamp and warm colour LED lamp, and said cool colour LED lamp and warm colour LED lamp all electrically connect with the LED control circuit.

As improvement; Said LED control circuit comprises governor circuit, cool colour LED lamp drive circuit, warm colour LED lamp drive circuit; The input of said cool colour LED lamp drive circuit and warm colour LED lamp drive circuit all electrically connects with the output of governor circuit; The output of cool colour LED lamp drive circuit and warm colour LED lamp drive circuit electrically connects with cool colour LED lamp and warm colour LED lamp respectively, and temperature sensor and governor circuit electrically connect.

The intelligent LED street lamp that the utility model is set forth; Compared with prior art; Its beneficial effect is: the utility model is through temperature sensor acquisition environment temperature; Control the glow color of LED street lamp according to the variation of environment temperature through the LED control circuit, to represent the variation of this environment temperature.The utility model is a warm colour light at the lower LED street lamp glow color in season of environment temperature, makes the people feel comfortable; Equally, the season of sweltering heat LED street lamp glow color be the cool colour light time, can make people's feeling cool, than hommization and intellectuality, and can make prolong one times the service life of LED street lamp, can be widely used.

Description of drawings

Accompanying drawing 1 is the structural representation of a kind of intelligent LED street lamp of the utility model;

Accompanying drawing 2 is the schematic block circuit diagram of a kind of intelligent LED street lamp of the utility model.

The specific embodiment

Below, in conjunction with the accompanying drawing and the specific embodiment, a kind of intelligent LED street lamp of the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.

Like Fig. 1, shown in Figure 2, a kind of intelligent LED street lamp, it comprises lamppost 5, is fixed on the light fixture 6 on the lamppost, and light fixture 6 is provided with a PCB substrate (figure does not show), on this PCB substrate LED lamp 3 is installed.For the variation with environment temperature of the glow color of realizing the utility model LED street lamp changes; Compare hommization and intelligentized LED road lamp device; LED lamp 3 includes cool colour LED lamp and warm colour LED lamp, and this cool colour LED lamp and warm colour LED lamp can certainly be one for a plurality of all.Be installed with temperature sensor 4 in the electric door 8 of lamppost 5 downsides, the PCB substrate is provided with a LED control circuit 2, and temperature sensor 4 all electrically connects with LED control circuit 2 with LED lamp 3.

Concrete operation principle is: LED control circuit 2 comprises governor circuit 21, cool colour LED lamp drive circuit 22 and warm colour LED lamp drive circuit 23; The input of cool colour LED lamp drive circuit 22 and warm colour LED lamp drive circuit 23 all with the output electric connection of governor circuit 21; The output of cool colour LED lamp drive circuit 22 is electrically connected to cool colour LED lamp, and the output of warm colour LED lamp drive circuit 23 is electrically connected to warm colour LED lamp.External ac power source links to each other through the LED power subsystem 1 in the installing mechanism 7 at lead and same laying temperature sensor 4 places; Via delivering to governor circuit 21 after LED power subsystem 1 transformation, rectification, the filtering; Temperature sensor 4 electrically connects with governor circuit 21; Temperature sensor 4 acquisition environment temperature convert this environment temperature one control voltage to and send into governor circuit 21.Governor circuit 21 is controlled the break-make of cool colour LED lamp drive circuit 22 and warm colour LED lamp drive circuit 23 according to the difference of this control voltage, promptly realizes the glow color of LED control circuit 2 control LED lamps under the different environment temperature.In the utility model preferred version, in environment temperature lower season, 23 conductings of governor circuit 21 control warm colour LED lamp drive circuits, warm colour LED lamp work this moment, LED lamp 3 glow colors are warm colour light, make the people feel warm, comfortable; In like manner, in the season of sweltering heat, 22 conductings of governor circuit 21 control cool colour LED lamp drive circuits, cool colour LED lamp work this moment, LED lamp 3 glow colors are cool colour light, can make people's feeling cool, make environment hommization more, product is functionalization more also, intellectuality.Simultaneously, cool colour LED lamp and the alternation of warm colour LED lamp can make also to prolong one times the service life of LED street lamp.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
