Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-2, a kind of device stablizing LED light source energy, including galvanic couple the 1, first power supply 2, fixed resistance 3,
The two ends of galvanic couple 1 it are connected to after second source 4 and variable resistance 5, described first power supply 2 and fixed resistance 3 series connection, described second
The two ends of galvanic couple 1, the electricity that described galvanic couple 1 is made up of it is connected to two kinds of semi-conducting materials after power supply 4 and variable resistance 5 series connection
Even.
Use the method that the described device stablizing LED light source energy stablizes LED light source energy, be in outside based on LED
The principle that under conditions of temperature constant, energy of light source tends towards stability, utilizes semi-conducting material along with the change of size of current and heat absorption
The principle being directly proportional with exothermal efficiency, adjusts the big of electric current by galvanic couple 1 by the resistance sizes adjusting variable resistance 5
Little, and then adjust the heat absorption of semi-conducting material and the power of heat release, make the energy constant through semi-conducting material, so that partly leading
Body material constant temperature, then LED 6 is wrapped in the semi-conducting material of constant temperature, under conditions of making LED 6 be operated in constant temperature, thus
The energy making LED 6 tends towards stability.
When being provided without the present invention, as it is shown in figure 1, the voltage U2 of second source 4 is constant, the resistance R2 of fixed resistance 3 is constant,
LED 6 is started working, and light intensity detector 7 detects energy of light source and shows in display screen 8, and now, light intensity can be with
The change of temperature residing for LED 6 and change；After using the present invention, as in figure 2 it is shown, LED 6 is wrapped in semi-conducting material
In, adjust the resistance R1 of variable resistance 5, until the temperature stabilization of semi-conducting material is to temperature required, now, even if temperature becomes
Changing, the energy hunting of LED 6 is the most little.
The present invention, by adjusting the variable resistance 5 in circuit, utilizes the Peltier effect of semi-conducting material to make quasiconductor material
The temperature constant of material, is wrapped in the LED 6 in work in the quasiconductor of constant temperature, makes LED 6 working temperature constant finally reach
To the function of LED 6 energy stabilization, described LED 6 energy stabilization, the LED 6 referring to utilize light intensity detector 7 to record
It is little that light intensity elapses change over time, it is adaptable to uses the metering of LED, colorimetric module, or on-line checking instrument.
The present invention uses semi-conducting material as temp-controlling element to control the temperature of LED 6, the work of regulation semi-conducting material
Making electric current, it is achieved that the temperature constant of LED 6, the stability composing temperature control effect and LED carries out test and shows, thermostatic control
Method can effectively overcome the variation of ambient temperature impact on the temperature of LED 6, under identical testing conditions with without constant temperature phase
Ratio, the LED light source residual noise with temperature incubation function is the most on the low side, especially ensure that the stability of on-line checking instrument, meets
National environmental protection authentication requesting.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment party
