Description
Technical field
This novel proving installation that relates to a kind of solid-state illumination product efficiency particularly relates to the proving installation of a kind of LED (Light Emitting Diode) lamp or light fixture efficiency.
Background technology
Solid-state illumination (Solid-StateLighting, SSL) as a kind of brand-new lighting engineering, utilize semi-conductor chip as luminescent material, directly convert electrical energy into luminous energy, it is luminous from the tungsten filament of incandescent lamp luminous different with tricolor powder electricity-saving lamp, semiconductor light-emitting-diode (LED) adopts electroluminescence, and photoelectric transformation efficiency is higher.Solid-state illumination has the characteristics such as energy-saving and environmental protection, life-span are long, non-maintaining, easy to control.Therefore, the solid-state illumination product more and more is subject to the welcome in market, and its development is also more flourishing.Along with manufacturer's rapid progress on the lifting led function of light emitting diode (LED), existing illumination scheme is not only paid close attention to economic benefit, also can special concern LED every watt of lumen (Lumen) amount that can produce, the namely light efficiency of lamp.This just need to detect simultaneously to the luminous flux (lm of unit) of solid-state illumination product and the power (W of unit) in the circuit, considers the luminescence efficiency (lm/W) of solid product with their ratio.
Yet, the luminescence efficiency of solid product is detected, prior art mainly contains minute two methods, and a kind of is the use darkroom, utilizes LED lamp distribution Performance Test System that the parameters such as the luminous flux of LED lamp or light fixture and power are tested; Another is that to utilize little integrating sphere (diameter 0.5m) be to carry out photochromic electrical testing to led chip, LED encapsulation.Integration sphere light source system has advantages of that measuring speed is fast and need not the darkroom, and it is minimum that Air Flow reaches, and temperature is not subject to potential airflow influence in the temperature-controlled chamber in the spheroid.But, the second and be not suitable for luminous flux and the isoparametric test of power to LED lamp or light fixture.
The utility model content
The technical problems to be solved in the utility model is for above-mentioned deficiency of the prior art, and a kind of LE light fixture optics and electrical characteristic test device are provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme to realize: a kind of LE light fixture optics and electrical characteristic test device, comprise spectroanalysis instrument and power measuring system, and it is characterized in that, described device also includes integration sphere light source system;
Described integration sphere light source system comprises integrating sphere shell and specimen holder;
Described integrating sphere shell is hollow ball shape, and its diameter is 1.5m;
Described integrating sphere shell is that two hemisphere shells form;
Described spectroanalysis instrument is connected with optical fiber by power lead with integration sphere light source system;
Described power lead is two.
Utilize large integration sphere light source system, can carry out the test of luminous intensity distribution performance, especially luminous flux to most LED lamp or light fixture.And existing photochromic electrical testing system can only carry out photochromic electrical testing to led chip, LED encapsulation.Compared with the LED lamp distribution Performance Test System that uses the darkroom, integration sphere light source system during the use basis is novel then can reduce Air Flow to the impact of test environment temperature, spectral measurement speed is fast, spectral information passes through integral and calculating, its test and record are also more abundant, make the result of its measurement more accurate.

Embodiment
Below in conjunction with specific embodiment the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of LE light fixture optics and electrical characteristic test device comprise spectroanalysis instrument 1, power measuring system 3 and integration sphere light source system 2; Integration sphere light source system 2 includes integrating sphere shell 21 and specimen holder 22; Integrating sphere shell 21 is hollow ball shape, and its diameter is 1.5m; The integrating sphere shell is that two hemisphere shells form; Spectroanalysis instrument and integration sphere light source system are connected with optical fiber by power lead 42 and are connected; Power lead 42 is two.
As shown in Figure 1 and Figure 2, at first, LED lamp or light fixture are put on the specimen holder 22 of integration sphere light source system 2, the power lead of LED lamp or light fixture is drawn out on power lead 42 connection terminals of integrating sphere shell 21 bottoms from integrating sphere shell 21 by optical-fibre channel, the out-put supply line 42 of spectroanalysis instrument 1 is connected on this connection terminal, is connected with the power lead of LED lamp or light fixture.By adjusting the alternating-current measurement supply voltage frequency values on the spectroanalysis instrument 1, lightening LED lamp or the required electrical quantity of light fixture are input on LED lamp or the light fixture by power lead 42, on the power lead 42 of power supply, be linked into the power test system 3 from L, N utmost point leading-out terminal respectively, the LED lamp on the integration sphere light source system 2 interior specimen holders 22 or the consumed power of light fixture are tested.Until LED lamp or light fixture light stable after, use spectroanalysis instrument 1, by optical fiber 41, the LED lamp on the integration sphere light source system 2 interior specimen holders 22 or the parameters such as luminous flux of light fixture are tested and are analyzed.At last, the luminous flux that obtains on the spectroanalysis instrument 1 divided by the consumed power value that shows in the power test system 3, is drawn the efficiency of LED lamp or light fixture.
The above only is the utility model better embodiment, and every any trickle modification, equivalent variations and modification of above embodiment being done according to the technical solution of the utility model all belongs in the scope of technical solutions of the utility model.
