Russia- Installation and training for Integrating Sphere Test System

Recently, there is a Russian customer who purchased the LPCE-2 (LMS-9000A) High Precision Spectroradiometer Integrating Sphere System from LISUN. This customer is a relatively large local luminaries manufacturer, just built a new laboratory and was perfecting the test equipment.

The installation & training lasted one day. Before our engineer arrive there, they had already connected the lines according to the user’s manual. Below is a picture of customer training:

Waterproof Test Equipment Analysis in China Market

Waterproof Test Equipment Analysis in China Market

Waterproof grade reflects the ability of moisture-proof of products. Especially for outdoor activities, it is unavoidable to be in the harsh environment of high humidity. The sealing and water-proof ability of the instrument is very important to ensure the safe of operation and life of the instrument.

At present, there are many manufacturers producing waterproofing equipment on the market. What are the advantages of LISUN waterproof equipment compared with other manufacturers? There are some advantages for LISUN waterproof in below:

1. On the side of excellent cost performance, In test equipment market, the quality of LISUN waterproof equipment is good than the waterproof equipment of most of suppliers. Please kindly see Figure 1 and Figure 2. Besides, the price of LISUN waterproof test equipment is very competitive in market. Right price with good quality is cost-effective products for our customer to make a good choice for test equipment. Compare to Figure 2, visibly, the surface of material of LISUN waterproof equipment in Figure 1 (LISUN Model:JL-34) has high gloss. And the surface of material in Figure 2 (Other supplier’s Model) have poor gloss. Good material with high gloss makes the equipment more beautiful visually. Regarding to choosing material, LISUN use SUS304 stainless steel as raw material. One more, the regulator in Figure 1 (LISUN Model JL-34) is much better than the regulator in Figure 2.

[caption id="attachment_11190" align="alignnone" width="300"] Figure 1: Surface of IPX3-IPX4 (LISUN Model:JL-34)[/caption]

[caption id="attachment_11191" align="alignnone" width="329"] Figure 2: Surface of IPX3-IPX4 (Other Supplier’s Model)[/caption]

2. Speaking of structure of IPX3-IPX4, please kindly see Figure 3 and Figure 4 in below. The waterproof test equipment in Figure 3 (Other supplier’s Model) is Wall-Hanging Split Type, but the waterproof test equipment in Figure 4 (LISUN Mode: JL-34) is Two Cabinets Type. Compare to Wall-Hanging Split Type, two cabinets type is easy to carry. Besides, the cabinets of LISUN model JL-34 can be mounted wheels at the bottom, which is more easier for operator to carry and adjust placement.

[caption id="attachment_11192" align="alignnone" width="296"] Figure 3: Wall-Hanging Split Type IPX3-IPX4 test equipment (Other supplier’s Model)[/caption]

[caption id="attachment_11193" align="alignnone" width="197"] Figure 4: Two Cabinets Type IPX3-IPX4 test equipment (LISUN Model:JL-34)[/caption]

3. With the view of production details for waterproof test equipment, we can see many welded junctions in Figure 5 and Figure 6(Other supplier’s Model), which not only affects appearance, but also makes it easier for water to erode equipment. please kindly see Figure 5 & Figure 6 & Figure 7 in below. In Figure 7(LISUN Model: JL-34), we can see that the surface of the equipment is clean and glossy, and there is no welded junction.

[caption id="attachment_11194" align="alignnone" width="316"] Figure 5: Production details (Other supplier’s Model)[/caption]

[caption id="attachment_11195" align="alignnone" width="323"] Figure 6: Production details (Other supplier’s Model)[/caption]

[caption id="attachment_11196" align="alignnone" width="231"] Figure 7: Production details (LISUN Model:JL-34)[/caption]

4. Speaking of turntable, we can easily judge the good or bad quality of turntable by through below Figure 8 and Figure 9. After waterproof test equipment is used for a long time, in below Figure 8 (Other supplier’s Model), we can find many rust spots on the machine. In below Figure 9(LISUN Model:JL-34), there is no rust spot on that machine. Thus it can be seen good material can make machine have good corrosion resistance and durability. The turntable of LISUN model JL-34 also mounted wheels at the bottom. This is also more convenient for the operator to move the turntable.

[caption id="attachment_11198" align="alignnone" width="220"] Figure 9: Turntable of IPX3-IPX4 (LISUN Model:JL-34)[/caption]

5. For swing pipe and spray nozzle for IPX3 and IPX4, compare to Figure 10, the quality of swing pipe and spray nozzle in Figure 11 is better and more elaborate .which also make operator control water flow accurately, and Good parts can make the equipment be used for long term.

[caption id="attachment_11199" align="alignnone" width="260"] Figure 10: IPX3-IPX4 Swing pipe and spray nozzle (Other supplier’s Model)[/caption]

[caption id="attachment_11200" align="alignnone" width="268"] Figure 11: IPX3-IPX4 Swing pipe and spray nozzle (LISUN Model:JL-34)[/caption]

6. Regarding to wire of waterproof, please kindly see Figure 12 and Figure 13 in below. Wire is exposing outside of equipment in Figure 12 (Other supplier’s Model). If operator use the machine for a long time in damp environment, that will be easy to make safety issue. So such design for waterproof equipment is not safe for operator. In Figure 13 (LISUN Model: JL-34), Wires are wrapped in plastic pipes, in that way, it can protect operator when operator use equipment. From a safety point of view, LISUN Model is also much better.

[caption id="attachment_11201" align="alignnone" width="293"] Figure 12: Wire of IPX3-IPX4 (Other supplier’s Model)[/caption]

[caption id="attachment_11202" align="alignnone" width="181"] Figure 13: Wire of IPX3-IPX4 (LISUN Model:JL-34)[/caption]

In all, before purchasing waterproof test equipment, please consider from different sides. Through the above comparisons, we believe that LISUN waterproof test equipment will be your best choice.

 

Photoelectric color performance detection of LED lights

 Photoelectric color performance detection of LED lights

The main parameters of the photoelectric color performance of LED lamps include: lamp power, power factor, luminous flux, output luminous efficiency, luminous flux maintenance rate, correlated color temperature, color rendering index, chromaticity tolerance, color coordinates, and beam of reflective cup MR16 or PAR lamp. Angle, light intensity and light intensity maintenance rate.

(1) The integrating sphere system with auxiliary lamps can quickly measure all of these photoelectric color performance parameters of the LED lamp. First place the LED light in the center of the integrating sphere, and test it with the illuminated auxiliary light when the LED is not lit. The auxiliary lamp is turned off and the LED lamp under test is turned on. After the test is stabilized, the color characteristic parameter of the lamp to be tested is obtained, and the luminous flux of the LED lamp under test is automatically calculated by software. If the auxiliary ball is not equipped with an auxiliary lamp, the LED lamp body itself will absorb part of the reflected light, and there will be some error in the luminous flux value. At the same time, the inner wall of the integrating sphere should also have a high reflectivity: 90%~98%. At present, most of the detection mechanism of the integrating sphere system has no auxiliary lamps, and the reflectivity of the inner wall of the integrating sphere is less than 90%. These integrating sphere systems cannot accurately measure the luminous flux of the LED lamps.

(2) The luminous flux of the LED lamp can also be measured by a distributed photometer. When testing, the γ angle range should be 180°, and the center of the lamp coincides with the center of the mechanical axis. The downside is that the test time is too long.

(3) The beam angle and light intensity of the reflector type MR16 or PAR lamp can be measured by a small bedroom distribution photometer. When testing, the mechanical and optical axes must be the same. The disadvantage is that the test posture is abnormal, and the test results need to be corrected.
