Moving Mirror Goniophotometer Introduction

Moving Mirror Goniophotometer Introduction

Lisun LSG-2000 Moving Mirror Goniophotometer System adapts the solution of rotating mirror in the center, it is widely applied in road lamp, room lamp, spot lights, stage lights, Mining lamp, Automobile lamp, traffic signal lamp and LED lamp etc. all kinds of luminaries for light distribution performance(light distribution curve) measurement, it can also test total flux, luminaries efficiency for all types of lighting sources. It can realize CIEA-α，CIEB-β，CIEC-γ measurement solution with different software. The test result can be directly used as the input data of the international lighting design software, and comply with the requirements of CIE, IESNA and other international and domestic standards.

 

Lisun LSG-2000 Moving Mirror Goniophotometer System can test spatial luminous intensity distribution, luminance intensity data, zonal luminance flux, luminance efficiency, coefficient of Utilization, luminance limitation curves glare, maximum ratio of distance to height, efficient luminescence angle, upper luminous flux, lower luminous flux, available average illuminance curve, Isocandela diagrams etc. photometry parameters, and voltage, current, power, power factor etc. electrical parameters.

Accuracy of angle: Class A.f1’<3% (Standard Class) or Class L.f1’<1.5%.

C angle：1) Rotating Range: 0°~360°; 2) Angle accuracy: 0.1°; 3) Angular Resolution: 0.001°.

γ angle: 1) Rotating Range: -180°～180°; 2) Angle accuracy: 0.1°; 3) Angular Resolution: 0.001°.

 

This system has 3 rotating axis. Main axis drives the reflective mirror rotate around the center point, reflect the light of the lamp to the detector. At the same time, auxiliary axis reverse rotates synchronously, always keeps the lamp bracket in the vertical position, to ensure the test lamp in normal ignite position in the measurement process, and achieve the lamp in the main axis direction measurement.

 

Lisun LSG-2000 Moving Mirror Goniophotometer System can work with a CCD spectroradiometer with USB interface to test spatial CCT distribution and other spectral color parameters. The rotation motor is from Japan MITSUBISHI MOTORS to make the system rotate very smoothly and stably. And it uses Germanic Angle decode system to ensure the system accuracy. It adapts RS-232 standard interface, it can be connected to PC.

 

Lisun LSG-2000 Moving Mirror Goniophotometer System is widely applied to Luminaries manufacturing enterprise and lab, such as Sharp Electronics in Memphis TN(USA), CS TECH MEXICO, S.A. DE C.V. (Mexico), DORADO Praha s.r.o. (Poland) etc. The reason why Lisun can win some many customers is because we always practice the motto of right products, right price and right service. Lisun will continue feedback good quality products and superior service in the feature.

 

IP Waterproof and Dustproof Rating Test

IP Waterproof and Dustproof Rating Test

 

Purpose of the test: to assess the ability of the material to prevent solids and liquids from entering the external shell

Detection range: electrical and electronic equipment, automotive aircraft and other parts

 

IP level (waterproof and dustproof) definition

IP waterproof and dustproof, refers to the protection level of electrical equipment, in accordance with its ability of preventing external objects intrusion, waterproof, moisture-proof and dustproof characteristics to be graded. The external objects include tools, human fingers, etc. which are not accessible to the live parts of the lamp to avoid electric shock. IP protection level is composed of two figures, the first number represents the level of dustproof ability for lamps, and the ability of preventing foreign objects intrusion; the second number represents the level of anti moisture and water for lamps. The larger the number is, the higher the degree of protection is. For example, IPXX.

 

The IP rating system provides a method for classifying products by the levels of waterproof, dustproof and anti-collision for electrical equipment and packaging. This system is approved by most European countries and was announced in IED529 (BS EN 60529: 1992) External Packing Protection level (IP code).

 

The degree of protection is mostly followed IP by two numbers, and the numbers are used to clarify the level of protection. The first figure indicates the extent of the equipment against the dust, or the extent to which people are protected from harm in a sealed environment. The second figure indicates the waterproof level of the device.

 

0 No protection

1 Can withstand solid material with length is more than 50mm. For example, hands accidentally touch; can withstand the vertical drop of water.

2 Can withstand solid material with diameter is more than 12mm, and length is no longer than 80mm. For example, fingers; can withstand a direct injection of water at a vertical angle of 15 °.

3 Can withstand solid material with diameter is more than 2.5mm. For example, tools or wires; can withstand direct jetting of water at a vertical angle of 60 °.

4 Can withstand solid material with a diameter is more than 1.0mm. For example, small wires; can withstand water spray from any direction- allowing limited access.

5 Dustproof, limited access (no harmful deposits). Can withstand low pressure water jet from any direction - allowing limited access.

6 Dust is difficult to enter, completely dustproof. Can withstand strong water column jet from any direction - allowing limited access.

7 Allowing for putting into 0.15m-1m depth water for a short time which can be up to 30 minutes.

8 Can withstand long-term soaking under pressure.

High and low temperature test

In natural environment, temperature and humidity are two indivisible natural factors. Due to different geographical locations in different regions, the temperature and humidity effects generated are also different. This test is used to confirm the products’ adaptability during storage, transportation and usage in the climate of some certain temperature and humidity. Severe levels depend on the high / low temperature, humidity and the time of exposure.

High temperature test is introduced in detail: this test is used to determine the adaptability of the products to store, transport and use under the conditions of high temperature and climate. The severity of the test depends on the temperature of the high temperature and the duration of the exposure. Reference test standards: GB/T 2423.2, IEC 60068-2-2, IEIA 364, MIL-STD-810F and so on.

Low Temperature Test: This test is used to confirm the products’ adaptability of storage, transportation and usage in the climate of the low temperature and humidity. Severe levels depend on the low temperature, humidity and the time of exposure.

Reference standards: GB/T 2423.1, IEC60068-2-1, EIA 364, MIL-STD-810F, etc..

Temperature shock test: This test is used to confirm the products’ adaptability during storage, transportation and usage in the climate of abrupt temperature change. Severe levels depend on the high/low temperature, dwell time and cycle number. Reference standard: IEC60068-2-14, GB2423.22, GJB150.5, etc..

High and low temperature test chamber is mainly aimed at the electrical, electronic products, components, and other materials’ adaptability during storage, transportation and usage in the high/low temperature.

The test equipment is mainly used for the products in accordance with national standards or user requirements, in low temperature, high temperature, conditions, the physical and other related characteristics of the environment simulation testing, testing, to determine the performance of the product, whether it is still able to meet the predetermined requirements, so as to provide product design, improvement, identification and factory inspection.

High and low temperature test box to prohibit the test items: 1) Explosive; 2) Combustible; 3)Tinder.
