Abstract
The utility model discloses a light emitting diode (LED) spot lamp capable of realizing intelligent brightness regulation, which comprises a lens, a heat radiation lamp cup, an aluminum base plate, a plurality of LEDs, a base cover, a lamp head, a power supply supplying device and a patch thermistor, wherein the LEDs are arranged on the aluminum base plate, and the patch thermistor is arranged on the aluminum base plate and is connected in series with the LEDs at the output end of the power supply, so the output current of an LED driving power supply can be controlled, the LED heating quantity is controlled, and the intelligent brightness regulation is carried out; when the work environment temperature is very low and the temperature rises after a period of work of the spot lamp, the temperature detected by the thermistor Rt is very low, at the time, the resistance value of the thermistor becomes small, the current becomes heavy, and the brightness of the LEDs becomes high; and when the work environment temperature is high and the temperature rises at a period of work of the spot lamp, the temperature detected by the thermistor Rt reaches the design value, at the time, the resistance value of the thermistor becomes great, the current becomes small, the brightness of the LEDs becomes low, the temperature of LED lamp pins can also be controlled, so the brightness is automatically regulated, and the LEDs and the spot lamp are protected.
Description
Technical field
The utility model relates to a kind of shot-light, relates in particular to a kind of LED shot-light.
Background technology
The brightness of LED shot-light on the market at present can not be carried out the intelligence adjusting along with environment temperature, the situation that environment temperature is very low or very high, the output current of power supply all is constant, if environment temperature is than higher, after adding the temperature rise of work a period of time of LED shot-light, the lamp base temperature can be very high, can cause the shortening in the life-span of the light decay of LED and shot-light like this.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of LED shot-light of can intelligence adjusting brightness is provided.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of LED shot-light of can intelligence adjusting brightness, comprise a heat radiation Lamp cup, be installed on heat radiation Lamp cup upper end lens, be fixedly connected on the aluminium base of heat radiation Lamp cup and be installed on lamp holder, that a plurality of LED, on the described aluminium base are connected in the bottom of heat radiation Lamp cup lower end and are connected in the bottom lower end and be connected in power supply unit in the bottom, comprise that also one is installed on the paster thermistor of described aluminium base, described thermistor is connected with LED at the output of power supply.
Described LED shot-light also comprises second resistance in parallel with described thermistor.
The beneficial effects of the utility model are: paster thermistor Rt is installed on aluminium base, and thermistor Rt connects with LED at the output of power supply, so just can control the output current of LED driving power, thereby the caloric value of control LED is carried out brightness intelligence and is regulated.When operating ambient temperature is very low, add the temperature rise after shot-light work a period of time after, it is lower that thermistor Rt detects temperature, at this moment will diminish by resistance, it is big that electric current becomes, LED brightness uprises; When operating ambient temperature is very high, after adding the temperature rise after shot-light work a period of time, when thermistor Rt detects temperature arrival design load, at this moment resistance becomes big, electric current diminishes, LED brightness step-down, and LED lamp base temperature also obtains and can control, automatic brightness adjustment like this, thereby protection LED and shot-light; And the parallel connection by two resistance, the better variation of controlling resistance, but also help protecting thermistor Rt.
Description of drawings
Fig. 1 can intelligence adjusts the schematic diagram of the LED shot-light of brightness for the utility model;
Fig. 2 can intelligence adjusts the schematic diagram of the LED shot-light of brightness for the utility model;
Fig. 3 can the intelligent explosive view of adjusting the LED shot-light of brightness for the utility model.
The specific embodiment
Describe the LED shot-light of can intelligence adjusting brightness in detail hereinafter with reference to accompanying drawing according to the utility model embodiment.
As shown in Figure 1, 2, 3, the LED shot-light of can intelligence adjusting brightness of the present utility model comprises lens 1, an aluminium base 2 and is installed on a plurality of LED (being example with LED1, LED2, three of LED3 in the present embodiment), a heat radiation Lamp cup 4, a power supply unit 5, a bottom 6 and a lamp holder on the described aluminium base 4.Wherein, described lens 1 are fixed in heat radiation Lamp cup 4 upper ends by UV glue, aluminium base 2 is fixed in heat radiation Lamp cup 4 by screw 3, and described heat radiation Lamp cup 4 lower ends and bottom 6 upper ends are fixed by heat conductive silica gel, and power supply unit 5 is fixedly connected on bottom 6 by adopting the AB casting glue, in, bottom 6 lower ends are provided with draw-in groove 61 and external screw thread 62, corresponding, inside, lamp holder 6 upper end is provided with stuck point and internal thread (figure does not show), thereby both can be by being threaded, and fix by the stuck point draw-in groove simultaneously.
The utility model can also comprise a paster thermistor Rt by the intelligent LED shot-light of adjusting brightness, described thermistor Rt is installed on aluminium base 2 (because the temperature of aluminium base 2 is consistent with LED lamp base temperature), and connect with LED at the output of power supply, so just can control the output current of LED driving power, thereby the caloric value of control LED is carried out brightness intelligence and is regulated.When operating ambient temperature is very low, add the temperature rise after shot-light work a period of time after, it is lower that thermistor Rt detects temperature, at this moment will diminish by resistance, it is big that electric current becomes, LED brightness uprises; When operating ambient temperature is very high; after adding the temperature rise after shot-light work a period of time; when thermistor Rt detects temperature arrival design load; at this moment resistance becomes big; electric current diminishes, LED brightness step-down, and LED lamp base temperature also obtains and can control; automatic brightness adjustment like this, thereby protection LED and shot-light.
In the present embodiment, also the output of power supply be provided with one with second resistance R 1 of thermistor Rt, the parallel connection by two resistance like this, the better variation of controlling resistance, but also help protecting thermistor Rt.
Above disclosed only is preferred embodiment of the present utility model, can not limit the scope of the utility model right certainly with this, with this equivalent variations of being done according to the utility model claim, still belongs to the scope that the utility model is contained.
