What is an Lighting Equipment?

A semiconductor device that emits light by running current

LED

  • LIGHT

  • EMITTING

  • DIODE

Features of LED

  • There is (±) polarity.

  • Rated voltage / current is different depending on the element.

  • Response speed is very quick.

  • High efficiency = low power consumption

  • Long life (some brightness deterioration due to natural heat).

  • Resistant to switching.

  • Resistant to vibration and shock.

  • Element itself is waterproof.

  • Bullet type and chip type are common.

  • Many of LED has the directional light.

Lifetime※Values shown do not represent the estimated life of individual LED elements and are not garanteed.

the lifetime of LED lights is about 40000 hours

Response

LED response time is 1/1000th that of a lightbulb

Power consumption

LED power consumption is 1/5th of a lightbulb

LED lifetime

Due to its very nature, an LED will not completely cease lighting up, unlike an incandescent lamp which will no longer light up once the filament wears out.
However, over time the LED’s light transmission rate will decrease and its light flux will degrade due to the degradation of the LED chip and the resin that seals the chip. Accordingly, the life of an LED is defined as the time it takes for LED luminance to decrease to 50% of initial luminance at an ambient temperature of 25°C; not the time it takes until the LED no longer lights up.

This definition of LED life also applies to LED lights with LED elements mounted.
The LED life time of required brightness is different depends on the customers from what percent of brightness is required compared to the initial. It may be said that it is the “past life”when it is 20% down from the initial brightness for those who think present brightness is just enough.

For the customers satisfied with 50% luminance of the light capacity in the initial stage, luminance decreased to 50% of the initial value may be considered to be still usable since required luminance can be maintained by increasing power supply as the luminance decreases.
Accordingly, we cannot uniformly define the life of light.

LED Brightness

Green (555nm) is good most sensitive, the human eyes are opposite the green in applications such as visual inspection.
However, in the image processing, even lighting that looks bright visually, can be dark in the image of the camera. You also need to consider the compatibility of the illumination wavelength and peak sensitivity characteristics with the individual camera.
The image is brighter when illumination wavelength and peak sensitivity of the camera are close.

Selecting Lighting Equipment.

Selecting lighting by wavelength.

  • Shorter wavelengths have larger scattering ratios, and are suited to surface inspection applications.
  • The contrast will worsten when the object and lighting are the same color.
  • We recommend selecting the low cost red lighting if it is not color processing.

The inspection purpose differs for each peak wavelength※The scattering ratio is inversely proportional to the 4th power of wavelength.
※Described wavelength is for reference only. There are some LEDs which does not fit in the above cases.

Wavelength characteristics

Relative issue intensity per peak wavelength

Comparison of Wavelength and objects

Whereas ordinary lighting is designed to make things brighter, in the field of image processing, lighting plays the key role of emphasizing only the areas of a subject that are of interest and capturing optimal images. Light bulb The color relationship between wavelength (lighting color) and objects, taking into account the relationships of typical complementary colors, is shown in the tables below.

  • color sample
  • red R irradiation
  • green G irradiation
  • blue B irradiation
  • white W irradiation
  • yellow Y irradiation
  • cyan C irradiation
  • magenta M irradiation

※The above tables depict a typical example only and may not be applicable depending on work characteristics (reflection, transmission, and absorption), and camera and lens (optical system).

Selecting Power Supplies for Lighting Equipment.

Pulse Light Control System.

Controlling the brightness by changing the pulse width.

  • Advantage

    • When turning on, the light luminance is relatively uniform because it is unlikely affected by the fluctuation of Vf of the element.
    • It has a longer operating life than contumuous lighting using the voltage light control because it turns on/off at a high speed.
  • Disadvantage

    • A camera with an ultra high-speed shutter may get dark when it synchronizes with the shutter.
    • Noise is likely to occur.

Pulse Light Control System

Voltage Light Control System.

Controlling the brightness by changing the voltage.

  • Advantage

    • It is unlikely that a camera may get dark when it synchronizes with a shutter in the same way as with the puls light control power supply.
  • Disadvantage

    • The light luminamce can not be unirom because the fluctuation of Vf of the element affacts significantly.

Getting the most out of Lighting Equipment

Do not use Lighting Equipment in high-temperature environments as doing so will speed up the rate at which luminance decreases and elements degrade.

LEDs tend to decrease in luminance and undergo accelerated element deterioration due to heat (heat generated by the LED itself). While the typical half-brightness value of an LED element is said to be around about 30,000 hours, an LED element used continuously under high temperatures may degrade in a shorter time and decrease in luminance.

To mitigate loss of luminance and degradation due to heat.

  • Improve the heat dissipative ability of the Lighting Equipment unit.

    It is recommended to install Lighting Equipment units in a structure or environment with good heat-dissipative capabilities, for example by taking steps to ensure adequate cooling.

    • Create air vents.

    • Attach a fan.

    • Attach the unit to a thick bracket or metal plate with good heat dissipative properties.

  • Turn lighting on and off in sync with image capture.

    Lighting Equipment handles switching well.
    Using the ability of Leimac light control power supplies to turn lighting on and off via an external signal, it is possible to extend LED life by only turning them on when required. (Not all power supplies come equipped with this function.)

  • Reduce light modulation volume

    When light is modulated with the volume down, the current flowing through the LED is lowered, and heat generation is suppressed.
    Setting the camera aperture as large as possible when selecting lighting, will allow you to select a lighting unit with more than adequate brightness.
    When using lighting continuously, it is recommended that light modulation volume is set to around 50%. (Even if luminance is reduced due to degradation, the volume can be increased to return to normal luminance.)

Lighting Equipment units should be moved as close to the subject as possible.

  • As LED elements themselves are small, Lighting Equipment units can be made compact and lightweight.

    Illumination is inversely proportional to the square of the distance, so moving the lighting unit close significantly increases light intensity. (We also design lighting solutions to suit various applications.)

  • When using direct lighting,

    Using a diffusing plate or polarizing plate can eliminate reflected lighting in some cases.

Lighting Simulation

We propose appropriate lighting without making a prototype through simple optical simulation.
· Custom / New development
· 3D design lighting etc.
Customized correspondence can be done from one unit.

  • Arrangement of light source (LED element)

    Arrange the LEDs based on the design drawing.
