December 24, 2015 at 13:17Light pulse meter LUPIN
When I first heard the name Lupin, I immediately remembered the anime about the merry aristocrat-thief, although there the main character was called Lupine and this is just a coincidence. In any case, the name for the measuring device is not trivial and it’s good that it wasn’t named, for example, as LUX-3418 or something like that. So what is hidden in the box and how will it be useful? Let's get a look.
The device is packed quite modern well, except that the packaging design does not reach the “great” mark a little, but already under the top cover there is a box decorated in a minimalist style and it already looks quite stylish.
Inside, everything lies in individual cells cut out in a foam base, for this a big plus.
In general, the packaging experience is only positive. The box is even covered with a matte lamination which creates a pleasant tactile sensation. And the equipment, in addition to the instructions, also contains a micro-USB cord and a charger, plus a bonus is a cord around the neck, for those who will do a lot of measurements, but more on that later.
We take out the light pulse meter and meet him by his clothes. Visually, it is quite simple, in the design it is clearly adapted to the development engineers, and not vice versa. But everything is tactile on top. Lupine is covered with a soft-touch coating and lies perfectly in the hand, I think that due to the velvety surface, he will not want to fall out of his hands, even if they are wet.
The device itself is quite ascetic, it has only 3 control keys, one hole for a micro-USB plug, a rotating eye with a sensor, and a pair of attachment ears for the cord.
Controlling the device is as simple as pressing a button. Actually, when you press any button, it turns on, when you press another, it switches to the mode corresponding to the key.
There are only 3 buttons, as noted earlier, and they correspond to 3 modes:
- brightness measurement in cd / m2
- illumination measurement in lux (lx)
- and light source ripple measurement in%.
The last one corresponding to the “P” key is the most interesting. I immediately tested my working monitor and compared the result with the recommended indicators in the table in the instructions. My monitor turned out to be normal (well, still, a monitor for that kind of money would be bad). But colleagues were not lucky. With a pulsation rate for monitors up to 5%, my colleague showed 110 - 119%. I don’t know how this is possible, but a colleague said that his eyes really often get tired.
In general, having measured all the monitors in the district and identifying a couple of dysfunctional ones, my friend went to IT specialists to demand a replacement, referring to my device :) I honestly thought that IT specialists would ignore him, but they became interested in lupine and even went to measure all of their own. And they even managed to reveal an interesting pattern that when the brightness of the monitor is increased, the ripple returns to normal. If it weren’t, it would be even more uncomfortable to work with the brightness turned to maximum. In general, the monitor was replaced, and I concluded that the ripple arose from a worn monitor backlight. And I have a more modern monitor with LED backlighting from here, and low ripple and the disappearance of ripple on an ordinary lamp when the brightness is raised - in fact, a higher voltage was applied to it, which equalized the ripple of the light.
And here, by the way, the pulsation on my old Galaxy S3 is already much higher than normal, it’s good that I don’t watch movies on it, although I read the books and you know why I had red eyes at that time 8) We
pulled off the monitors, although In fairness, I also measured the old aimak of 2009 at home, the indicators were normal.
I also measured the pulsation of home LED lamps in various modes and the German WOLTA lamps showed themselves best. Even dimmers in various modes from minimum to maximum showed ripple within normal limits. But ECOLA lamps pulsate more. Well, I rarely use them, although they shine in my type in my office (on the balcony ...).
Ripple in the bathroom:
At maximum brightness:
At minimum:
But what are we all about pulsation and pulsation, because the device is primarily a light pulser and everything is much more interesting here ...
Measurements on the balcony:
Measurements in the bathroom:
Measurement of a daylight table lamp:
And ordinary room wall lamps
Sunlight, and in principle light in general, influences us quite strongly. I think it is very important that the lighting is comfortable enough - not dim and not very bright. Although dim light is also useful, it is rather a specific application. With the proper selection of lighting, you can work quite productively, I remember in Soviet times there was a number of recommendations on how to illuminate a student’s place :) And it’s not only people who need the right lighting. In principle, this is vital for plants. For example, for many types of plants it is important what brightness the light hits them on the leaves and in this case this device will be very useful when setting up lighting, for example, in a greenhouse.
At my home, almost all light sources have dimmable controls and the lighting can be configured most comfortably in a given time period. But what’s interesting in the bathroom is the mirror illumination, and it looks like it doesn’t shine very brightly outward - the light is white, even with a slight blue. But when measuring it turned out that the brightness is not so small, but it can be seen much worse.
I immediately remembered the discussion of LED backlighting and an example with an LED spotlight in someone in the yard. I did not understand how this is possible, that it shines brightly, my eyes get tired, but I see worse. In the bathroom mirror, I thought the light was just dim, but it turns out that he is an example, very close. Well, in addition to brightness, it is also not very good with ripple, but apparently the power supply is to blame, which was replaced by negligent repairmen who burned their own during installation.
Balcony spotlights, and what else, with such brightness :) shine excessively bright. Something got excited when I installed 4 pieces on each loggia. A total of 240 watts came out equivalent to incandescent lamps and in suites it is 224 cd / m2. I rarely turn them on :)
In general, having measured all the parameters at home and in the office and comparing them with the table, I came to the conclusion that almost everything is normal and, in principle, you can determine the parameters that are comfortable for yourself. But this is about comfort and is more about home. At work, if the lighting goes beyond the standards and you feel uncomfortable, this device will help to clearly argue the request to do something with the lighting and most likely they will listen to you. The work environment is often a common cause and concerns more than one person.
With regards to professional use, where a lace and a necklace would be useful ... Definitely with the help of the LUPIN Light Pulsemeter you can determine the backlight lamps of monitors that are on the verge of their lifespan. You can measure the brightness of the car headlights before and after restyling. I’m just dealing with this issue for myself, since the standard light on my car is generally slag. Those who collect flashlights can safely recommend this device to confirm the manufacturer’s declared lumens :) For myself, I will use the light pulse meter in difficultly lit scenes during video and photography. For example, in bright sunny weather on snow, a technique may incorrectly expose a scene and it’s good if the scene turns out to be less illuminated than it really is, but if there is overexposure it will be difficult to correct it and white holes will appear at the overexposure sites. And if you can still draw something on the photo, then with the video work will be added incredibly and it will be easier to reshoot or leave it as it is.
As a bonus, the
functionality of the device can be expanded if you connect it to a computer and receive data through a proprietary application. Then it will be possible not only to look at the data in the moment, but to observe the graph and the change in parameters over time.
This is what the information display in the program looks like:
At the end, I attach a link where you can purchase the LUPIN Light Pulse Meter
