APPLICATIONS:

LED tube parameter test requirements and methods

1. Luminance meter

Luminance meter is an instrument used to measure the brightness of a light source or the surface of an object. Using a luminance meter, you can see through the instrument

The area to be measured, sometimes this area is very small and must be observed from a long distance, so the luminance meter has

Lens and optical system, and use some form of diaphragm to isolate the measured area.

The working principle of the luminance meter is to measure the illuminance produced by the image of the surface to be measured on the surface of the photocell. This is like light

The illuminance generated on the surface of the battery is proportional to the brightness L of the measured surface and the aperture of the lens.

2. Goniophotometer

Goniophotometer is used to measure the light intensity around the luminaire, and draw the measured data in a suitable method for lighting

Engineers use. The equipment required to measure street lighting and indoor lighting fixtures is the same, and they are all polar coordinates

Photometer. What floodlights and airport signal lamps need is special equipment with long light path-angular distribution span meter.

2.1 Polar coordinate photometer

The simplest polar coordinate photometer is composed of a photovoltaic cell placed at one end of a long arm or on an arc track.

The photocell can rotate around the lamp to measure the light intensity at a known angle. The lamp is fixed on a rotating flat

On the stage, readings at any azimuth angle can be obtained. It is extremely important that only the light to be measured shines on

On the photocell. To exclude other stray light, you can add a baffle in front of the photovoltaic cell. Placement of the baffle

The position should be as limited as possible to the field of view to be consistent with the light cone emitted by the luminaire. In order to avoid the influence of stray light,

The polar coordinate photometer should be placed in a dark room.

2.2 Angular Distribution Photometer

Floodlights, translucent lamps, car headlights and other condensing lamps, they are concentrated, so the test distance should be

Much larger than astigmatism lamps. The detector should be far enough to see the entire reflective surface of the reflector. right

The narrow-angle floodlights commonly used in stadium lighting should have a measuring distance of about 33 meters. However, according to the international

It is stipulated that the test distance of car headlights is 25 meters. An important issue with long optical paths is that the photovoltaic cells should be fixed,

The lamp turns.
