Strength of directivity is about 20 to 30 m apart, it becomes a strong spot of circular shape of about 2.5 m.

Strength of directivity is about 20 to 30 m apart, it becomes a circular white strong spot of about 2.5 m. Compared to the 48 light infrared lights, this one light only has sensibly brightness of 3 to 4 vehicles or more and one car is 1000 mA consumption, so it is energy saving, resulting in total purchase price Then it seems to be cheap. This is excellent Excellent When compared with the 48 LED type I bought before, the enclosure is one size larger, the stay is also fascinating. It seems that the light intensity is also quite strong and the directivity is strong. Several screws for fixing are attached. Although it seems to be somewhat disappointing here other people are also told, there seems to be no treatment of a waterproof seal on the front glass, but if you check well, white silicone rubber twists to the front of the glass, It protrudes a little, is it for waterproof also for the screw part? It seems that silicone grease is also applied. As the products that are sent are rattling inside, when looking closely, one of the four black reflectors was off. The power supply cable is slightly thicker than the product of 48 LED, there is also a packing of white silicone rubber for waterproofing at the rear passage opening. please note! Infrared rays do not penetrate or penetrate usual windowpanes or car glasses. When installing this infrared projector from indoor to outdoor, infrared light will be reflected on the glass surface, so please be careful as it can not be used. When the packing of the front glass portion protrudes, it will not fulfill the function of waterproofing, so if there is no tool, cross the two thin flathead screwdrivers and insert it into the groove and turn it to the left Yukkuri left, white Since the packing fits into the slack groove, turn it to the right again and tighten it suddenly. "Reference materials" There are generally two types of infrared wavelengths, 850 nm and 940 nm. This product seems to be a product of 850 nm. · 850 nm system Normally commercially available night vision (LED looks light red in cameras with infrared mode, but the photographs are good at photographing and the amount of light is strong) · 940 nm type digital night vision (military model, etc., the amount of light is small and the picture is bad) In particular, in urban areas, the lower limit of darkness detection increases due to outdoor lighting or the like, and the reaching distance may be slightly shortened. Also, because it is high power at close range, the amount of infrared light will be over and there may be a white jump in level over. Looking directly at the IR beam with the naked eye will damage our eyes. (It can be prevented with ordinary glass eyeglasses.) When infrared light is on, do not look into the LED for a long time. It can not be used for devices that do not emit light when receiving infrared rays (matte black paint etc.). Although it can be used for dedicated night vision and CCD system etc. (It reacts particularly well to detergent bleaching agent used for human clothing), there are models that can not be used with CMOS method which does not detect infrared rays. If you want to know with a normal video camera etc, please check with the manufacturer of your equipment. However, even if it is a CMOS method, it can be used if it is a type of infrared detection method or the like. Removing the four internal reflectors will sacrifice the directivity, but it seems that the light diffuses well around the surroundings. (Reflector can easily come off)

You can use

To monitor joint waste storage space. Since the output was insufficient with the infrared ray of the surveillance camera, I added this. It is a wonderful help.

Infrared gland lighting

Looking at it, it got much brighter, and then the place where light is absorbed is still dark.

Reflecting

Although I bought 48 fine LEDs side by side, I failed but this is reflected clearly. If you place the place you want to copy in the horizontal direction instead of arranging it in the vertical direction, it illuminates widely up to far. Power supply adapter is sold separately (12 V 1 A) * Additional note ☆ 5 → ☆ 4 As the rain fell, the inside became cloudy. It is useless to use it in a place not hitting the rain or waterproof treatment. I can not help it because I have not written waterproofing into the explanation.

It is bright enough

When I first turned on I thought that it is broken thinking that something lights up when I say infrared. But when I looked at the surveillance camera at night, I found it usefully.

Use 1 year

Purchase, using more than one year passes, all LED lights up. No abnormality.

Strong Infrared Irradiation

The structure is solid, but it is not waterproof for outdoor use, so it is necessary to seal. It uses four high-power LEDs but is more noticeable because the red color is clearer than the type using many LEDs. Each LED has a reflector with a lens, so the beam is throttled and it is good to irradiate far. The LED mounting board of this instrument is made of metal, considering heat dissipation, and since the control section is a separate board, it is designed to be suitable for high power irradiation. Postscript 1: Sealed with bonds, but rain has gotten in due to typhoon rain. The front glass seems to be attached firmly to the aluminum frame, but I do not know if it can withstand high pressure water. Try to strengthen the seal of the front glass and the seal of the screwed part. Additional note 2: Since the power supply voltage is 12 V, since the irradiation amount can be changed by changing the voltage, the power consumption is measured by changing the voltage. It was constant at 4 W at 12 V to 10 V, turned off at 5.2 W at 9.2 V and below 6 V. Since this instrument is powerful, it lowered to 7 V to suppress saturation at a distance of about 6 m, but the infrared image was sufficient, and the red color was also not noticeable.

4 element type is nice feeling

In cameras without night vision mode, there is hardly any luminance even though it has high brightness, but in cameras with night vision mode the infrared filter goes off, so it gets brighter as illuminated with headlight, When it is lighted, since the irradiation range is narrow, we use 2 element lenses and wind the aluminum tape around the center ambient light sensor so as not to be influenced, but it is compact, easy to install and well priced I think that it is quite easy to use
