The prior art has a defect of the inaccurate measurement. The utility model comprises an LED excitation source, the phosphor powder arranged on the light path of the excitation source, and an optical receiver used for receiving the optical line sent out by the phosphor powder, wherein, a collector lens and a narrow bandpass filter are arranged between the LED excitation source and the phosphor powder. The utility model has the advantages of the accurate imitation of the lighting LED user mode, guaranteeing the accurate measurement of the phosphor powder, and easy operation.
Description
[technical field]
The utility model belongs to the optical radiation measurement technical field, is specially a kind of exciting and receiving trap of light emitting diode (LED) fluorescent powder test that be used for.
[background technology]
LED (white light LEDs) is widely used in lighting field, and the method that existing white light LEDs generally adopts blue-ray LED to add LED fluorescent powder is made, and the quality of fluorescent powder directly has influence on the quality of illumination LED product.Therefore, to the accurate measurement and the evaluation of LED fluorescent powder performance and quality, very important for control illumination LED product quality.
Also be not specifically designed at present exciting and receiving trap of LED fluorescent powder test, have only and adopt the fluorescent powder proving installation (such as luminous as the excitaton source excitated fluorescent powder) of conventional fluorescent that LED fluorescent powder is tested with the ultraviolet low pressure mercury lamp.But because that the luminescence mechanism of white light LEDs and conventional fluorescent exist is very big different, therefore this device is tested inapplicablely to LED fluorescent powder, and measuring result error is very big.
[utility model content]
In order to overcome the above-mentioned defective that exists in the prior art, the utility model provides a kind of exciting and receiving trap of fluorescent powders of light emitting diode test that be used for, and to be applicable to the test of LED fluorescent powder, improves measuring accuracy.
For this reason, the utility model is by the following technical solutions:
Be used for exciting and receiving trap of fluorescent powders of light emitting diode test, it is characterized in that: it comprises the LDD excitaton source, be located on the excitaton source light path fluorescent powder and in order to receive the optics receiving element of fluorescent powder emitted light, be provided with collector lens and narrow band pass filter between described LED excitaton source and the fluorescent powder.The light that the LED excitaton source is sent shines on the fluorescent powder after assembling through collector lens, excitated fluorescent powder is luminous, the optics receiving element receives the light that fluorescent powder sends, to record related data, the LED excitaton source can accurately be simulated the light source luminescent situation under the normal operating condition, guarantees that test result is accurate.Because the luminous peak wavelength of LED changes with factors vary such as its working current, junction temperatures, the direct optical excitation fluorescent powder that uses LED to send, the light that fluorescent powder sends is with instability, but test result lacks comparative, narrow band pass filter can become exciting light the light of the narrow wave band of spectrum, its peak wavelength is more stable, and test result is more accurate.The position of collector lens and narrow band pass filter can be changed according to actual needs.
As the further of technique scheme improved and replenish, the utility model adopts following technical measures: described LED excitaton source is a blue-ray LED, and blue-ray LED is widely used, and versatility is good.
Described excitaton source emergent light is vertical with the fluorescent powder upper surface, and the angle of described optics receiving element optical axis and excitaton source emergent light optical axis is 45 °, so that the compare test result.
The beneficial effects of the utility model are: can accurately simulate the user mode of illumination LED, guarantee that the fluorescent powder performance test is accurate, and easy to operate.
[description of drawings]
Fig. 1 is a structure principle chart of the present utility model.
[embodiment]
As shown in Figure 1 be used for exciting and receiving trap of fluorescent powders of light emitting diode test, be provided with collector lens 2 and narrow band pass filter 3 between LED excitaton source 1 and the fluorescent powder 5, the adjustable positions of collector lens 2 and narrow band pass filter 3 is changed.It is the blue-ray LED of 460nm that LED excitaton source 1 can adopt peak wavelength, its exciting light that sends is by after being placed on the collector lens collimation under the LED, narrow band pass filter by the below (also can be earlier by behind the narrow band pass filter again through the collector lens collimation) again, form the directional light of the narrow wave band of spectrum, on the upper surface of the tested fluorescent powder 5 of directional light vertical irradiation, thereby excitated fluorescent powder is luminous.Fluorescent powder 5 can place one to have in the measuring seat 4 of cavity and evenly flatten.Oblique 5 tops of fluorescent powder are placed with a collector lens as fluorescent optics receiving element 6, and the angle α of its optical axis and excitation beam optical axis is 45 °, and the light that fluorescent powder sends receives the optics inlet that optics is transferred to testing tool by fluorescence.
Wherein the half-peak value bandwidth of narrow band pass filter is less than 15nm, and the absolute value of the difference of the peak wavelength of its printing opacity peak wavelength and LED excitaton source is less than 10nm.
