Abstract
The utility model provides an LED (Light Emitting Diode) lamp temperature control device, mainly comprising a temperature control circuit unit, an LED lamp set and a temperature inductive element; when the temperature inductive element detects that the temperature of the LED lamp set is excessively high, a signal is sent to the temperature control circuit unit, and the temperature control circuit unit can reduce the voltage supplied for the LED lamp set; and the temperature of the LED lamp set is controlled by properly adjusting the voltage, thereby avoiding light decay or burn-out due to excessively high temperature of components of the LED lamp set.
Description
Technical field
The utility model relates to a kind of attemperating unit, relates in particular to a kind of LED light fixture attemperating unit.
Background technology
Since LED (light emitting diode) appearance, lighting apparatus has begun the revolution second time after Edison.LED has every advantages such as power saving, volume is little, efficient is high, plasticity is big, and present all kinds of industries there's no one who doesn't or isn't are devoted to utilize LED, make self more power saving of product, volume littler.
Yet LED is intact no all roses, and its maximum shortcoming is exactly that the operating temperature of LED light fixture group is higher than the critical-temperature that its part can bear.The operating temperature of LED bulb itself is very low in fact, but because the LED light fixture needs the configuration driven device can operate as normal, and chip and other parts that described driver includes can constantly heat up in working order; So LED light fixture group be in the higher environment of temperature, and its thermal source is mainly from driver when work.Yet the working environment of high temperature, meeting directly influence the life-span of every part in the LED light fixture group; Especially the chip in the driver, if work under the condition of high temperature continuously, described chip will soon damage, burn.Moreover, the too high light decay disappearance that also can cause brightness to reduce of operating temperature.
For solving the too high problem of temperature, in the streets many modes with LED light fixture group finned solve; Though finned helps to reduce temperature, but effect is still limited; Use for a long time or use in the place of improper ventilation, the fin effect that more seems is clear.
Summary of the invention
The utility model main purpose is to provide LED light fixture attemperating unit, controls the operating temperature of LED light fixture with regulation voltage.
For reaching above-mentioned purpose, the utility model provides a kind of LED light fixture attemperating unit, and it mainly comprises temperature sensitive member, temperature-control circuit unit and LED light fixture group, and described temperature-control circuit unit output power uses for described LED light fixture group; Described temperature sensitive member is used to detect the temperature of LED light fixture group, and sends a signal to described temperature-control circuit unit.
Compared with prior art, LED light fixture attemperating unit described in the utility model, with alternating current (as civil power) input rectification circuit unit, the rectification circuit unit exports the temperature-control circuit unit to after converting alternating current to direct current; The temperature-control circuit unit exports direct current to LED light fixture group again, makes LED light fixture group operate as normal; Temperature begins to rise after LED light fixture group work a period of time; When this moment, temperature sensitive member detected the critical value of its temperature arrival setting, just send a signal to the temperature-control circuit unit, voltage by temperature-control circuit unit reduction output power make LED light fixture group be able to low voltage work, and its temperature also can drop to safe range.By above-mentioned temperature sensor and then adjust the mode of voltage, can protect chip in the LED light fixture group and other parts can Yin Gaowen and damage, burn.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model.
Description of reference numerals: 11-rectification circuit unit; 12-temperature-control circuit unit; 13-LED light fixture group 131-temperature sensitive member; The input of 14-alternating current; The input of 15-direct current.
The specific embodiment
Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the utility model is above-mentioned.
Head sees also shown in Figure 1, LED light fixture attemperating unit described in the utility model mainly is made up of rectification circuit unit 11, temperature-control circuit unit 12, LED light fixture group 13 and temperature sensitive member 131, and its configuration mode is: rectification circuit unit 11 is connected to temperature-control circuit unit 12, temperature-control circuit unit 12 then is connected to LED light fixture group 13, and LED light fixture group 13 can in have temperature sensitive member 131, temperature sensitive member 131 more is linked to temperature control unit 12 to transmit signal in addition.
Main effect of the present utility model is: import 14 input rectification circuit unit 11 with alternating current and convert direct current to, and export direct current to temperature-control circuit unit 12; In addition, also can obstructed over commutation circuit unit 11, directly direct current is imported 15 temperature-control circuit unit 12.Then according to the demand of LED light fixture group 13, the electric power of output appropriate voltage uses for LED light fixture group 13 in temperature-control circuit unit 12; Yet, after LED light fixture group 13 is started working, each part and organism temperature are risen, temperature sensitive member 131 is responsible for the temperature of monitoring LED light fixture groups 13 at this moment; When reaching critical value, temperature sensitive member 131 just sends a signal to the voltage that temperature-control circuit unit 12 reduces supply when temperature is too high; And LED light fixture group 13 is worked under the electric power after the suitable step-down, and temperature also and then lowers.By aforementioned effect, the utility model can be protected LED light fixture group 13, its each part can not caused because of operating temperature is too high damage or light decay; Especially the chip that includes of LED light fixture group 13 very easily at high temperature burns, and controls temperature immediately by the mode of monitor temperature fit adjustment voltage, more can protect chip unlikely impaired.So the utility model can reach the concrete effect of monitoring temperature, protection part really.
In this case, when temperature sensitive member detects the temperature arrival capping value of LED light fixture group, will make the temperature-control circuit unit suitably reduce voltage; Otherwise, when temperature sensitive member detects the temperature arrival preset lower limit of LED light fixture group, can make the suitable booster tension in temperature-control circuit unit.
More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
