The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (hi) and object height (ho). The magnification equation is stated as follows:

2. Determine the image distance and image height for a 5-cm tall object placed 30.0 cm from a double convex lens having a focal length of 15.0 cm.

Evolved high-intensity transmission illumination. A chip-type transmissive lighting solution that delivers high output at an affordable price in a lightweight package.

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.)

The magnification of an image is both the hi / ho ratio and the -di / do ratio. Setting the -di / do ratio equal to -2 allows one to determine the image distance:

These two equations can be combined to yield information about the image distance and image height if the object distance, object height, and focal length are known.

※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).

The negative values for image height indicate that the image is an inverted image. As is often the case in physics, a negative or positive sign in front of the numerical value for a physical quantity represents information about direction. In the case of the image height, a negative value always indicates an inverted image.

As the origin of “Manufacturing,” we engage in the continuous improvment of minimizing the burden on the global environment, the social responsibilities.

The numerical values in the solution above were rounded when written down, yet unrounded numbers were used in all calculations. The final answer is rounded to the third significant digit.

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.

1. Determine the image distance and image height for a 5-cm tall object placed 45.0 cm from a double convex lens having a focal length of 15.0 cm.

As a demonstration of the effectiveness of the lens equation and magnification equation, consider the following sample problem and its solution.

From the calculations in the second sample problem it can be concluded that if a 4.00-cm tall object is placed 8.30 cm from a double convex lens having a focal length of 15.2 cm, then the image will be enlarged, upright, 8.81-cm tall and located 18.3 cm from the lens on the object's side. The results of this calculation agree with the principles discussed earlier in this lesson. In this case, the object is located in front of the focal point (i.e., the object distance is less than the focal length) and the image is located behind the lens. This falls into the category of Case 5: The object is located in front of F (for a converging lens).

The numerical values in the solution above were rounded when written down, yet unrounded numbers were used in all calculations. The final answer is rounded to the third significant digit.

As a restriction on the use of chemical substances related to the supply of environmentally friendly products, the revised RoHS Directive(2011/65/EU), which originally restricted the use of 6 hazardous substances such as lead, has been expanded to restrict 10 substances by adding 4 phthalates stipulated in Addendum (EU)2015/863. (The LED lighting, controllers, etc., of our company, Leimac, are compliant as of July 22, 2021 as they are categorized as monitoring and control equipment.)

Lighting Equipment handles switching well.Using the ability of Leimac light control controllers 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 controllers come equipped with this function.)

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.

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.

Secondary disasters (damage to equipment, lost opportunity, lost profit, and similar) incurred by the customer as a result of the malfunction of or damage to an Leimac product and any damages whatsoever shall not be subject to compensation.

In order to implement and continue this environmental policy, we engage in making all employees, suppliers and contractors aware of the policy. Moreover, we make it public and raise their awareness of environment.

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.

4. Determine the image distance and image height for a 5-cm tall object placed 10.0 cm from a double convex lens having a focal length of 15.0 cm.

Uniform illumination of objects with glossy/irregular surfaces. It is an indirect lighting that implement the LED around the ring-shaped light guide plate.

To determine the image height, the magnification equation is needed. Since three of the four quantities in the equation (disregarding the M) are known, the fourth quantity can be calculated. The solution is shown below.

The negative value for image distance indicates that the image is a virtual image located on the object's side of the lens. Again, a negative or positive sign in front of the numerical value for a physical quantity represents information about direction. In the case of the image distance, a negative value always means the image is located on the object's side of the lens. Note also that the image height is a positive value, meaning an upright image. Any image that is upright and located on the object's side of the lens is considered to be a virtual image.

The numerical values in the solution above were rounded when written down, yet unrounded numbers were used in all calculations. The final answer is rounded to the third significant digit.

When used in accordance with the instruction manual under usage conditions specified by Leimac, in the event of a product malfunction within the warranty period, Leimac shall repair the product free of charge or provide a replacement product.

The negative values for image distance indicate that the image is located on the object's side of the lens. As mentioned, a negative or positive sign in front of the numerical value for a physical quantity represents information about direction. In the case of the image distance, a negative value always indicates the existence of a virtual image located on the object's side of the lens. In the case of the image height, a positive value indicates an upright image.

From the calculations in this problem it can be concluded that if a 4.00-cm tall object is placed 35.5 cm from a diverging lens having a focal length of 12.2 cm, then the image will be upright, 1.02-cm tall and located 9.08 cm from the lens on the object's side. The results of this calculation agree with the principles discussed earlier in this lesson. Diverging lenses always produce images that are upright, virtual, reduced in size, and located on the object's side of the lens.

To determine the image height, the magnification equation is needed. Since three of the four quantities in the equation (disregarding the M) are known, the fourth quantity can be calculated. The solution is shown below.

Used in everything from oblique to back lighting application. It is a direct-type surface-emitting lighting that implements a high density on a plane bullet-type LED elements.

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

From the calculations in this problem it can be concluded that if a 4.00-cm tall object is placed 45.7 cm from a double convex lens having a focal length of 15.2 cm, then the image will be inverted, 1.99-cm tall and located 22.8 cm from the lens. The results of this calculation agree with the principles discussed earlier in this lesson. In this case, the object is located beyond the 2F point (which would be two focal lengths from the lens) and the image is located between the 2F point and the focal point. This falls into the category of Case 1: The object is located beyond 2F for a converging lens.

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 controller as the luminance decreases.Accordingly, we cannot uniformly define the life of light.

We have judged that our Lighting Equipment and extension cables are not covered by US safety standard, the Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use-UL61010-1, 6.3.1 a, due to their use of voltage under DC 48V.
