LED Lighting Use Examples

Precautions for Mounting

(1) Installation Location
As the instrument generates heat, mount it on a metal wall surface with efficient heat dissipation.

(2) Mounting Conditions
Make sure the back surface of the instrument fits closely against the wall surface.
This will increase the heat dissipation effect.

(3) Cable Mounting
After mounting the instrument, pay attention to the bending radius when fixing cables.
Confirm with the specifications of each product.

If the cable sags, fix it with cable clips or similar.

Cable Terminal Diagram The cable terminal is semi-stripped. (excluding LED bulbs)

LZ10 Mounting Method

The body and the mounting bracket (accessory) are separate

(1) Fit the mounting bracket to both ends of the body

(2) With the mounting bracket fit in

(3) Mount to control panel interior or wall

LZ10 Dedicated Bracket

(1) Mount body in dedicated bracket

Control Panel Mounting Example

Aluminum Frame Mounting Example

Aluminum Frame Mounting Method

(1) Insert retrofit nut into aluminum frame

(2) Screw-fasten body and retrofit nut

LED Lighting Before Use

Warning

Do not connect to devices or power supplies with dimmer function. (Otherwise damage or smoke emission may result)
Always turn power OFF before mounting, removing, or cleaning the instrument. (Otherwise, electric shock may result)
Do not drape paper or cloth, etc., over the instrument. (Otherwise, fire may result)
Never disassemble or modify the instrument. (Otherwise, fire or electric shock may result)

For the light bulb type

Never use for emergency lighting instruments, guidance lighting instruments, or mercury lighting instruments, etc. (Otherwise damage or smoke emission may result)

Caution

Do not touch while lit or immediately after turning off, as it is hot. (Otherwise, burns may result)
Do not look directly at the light emitting area while lit. (Otherwise, eye injury may result)
Do not hit it with objects or scratch it. (Otherwise, damage may result)
Use in a location with suitable environment. (Otherwise, damage may result)
Make sure the instrument mounting is secure. (Otherwise, a fall may result)
When dirty, wipe with a dry cloth. Do not use volatile organic solvents such as thinner, alcohol, or benzine.
(Otherwise, damage or discoloration may result)
Do not use in an environment exposed to volatile organic solvents or corrosive gases, etc. (Otherwise, damage may result)
If the power line is affected by inductive noise etc., isolate the power line. (Otherwise, damage may result)

For the light bulb type

Use a lamp at or below the instrument's specified wattage. (shortens lifetime)
Make sure it is mounted securely in the socket. (Otherwise, a fall may result)
Do not use where exposed to dripping water or high humidity. (Otherwise, damage may result)

Usage Precautions

Since the LED elements vary in emission color and brightness, these properties may slightly differ even in the same model.
Instrument illuminance, total luminous flux, and illuminance distribution are actual measured values and are not guaranteed.
Use as guidelines (reference values).
Use the color temperature value as a guideline (reference value).
When mounting the instrument, fix it to a metal surface (aluminum frame or steel wall) with efficient heat dissipation.
When wiring, always turn the power OFF first and make sure all wiring is correct.
The power source has polarity (+ and -), so connect it correctly. The white cable is for the + side and the black one for the - side.
Use voltage and current within the ranges indicated in the specifications.
Use in an environment within the temperature and humidity ranges indicated in the specifications.

For the light bulb type

Do not use a DC power supply.
Do not use with a sealed or nearly sealed instrument, as it will lead to temperature increase and shortened lifetime.
Do not use in a place where the lamp ambient temperature will exceed 40°C.

LED Lighting Terminology

LED

LED (Light Emitting Diode) means a semiconductor element which emits light when a current is run through it.
In recent years, LEDs have come to be used in traffic lights, large televisions, illuminations and so on. Compared to incandescent bulbs, they use approximately 1/3 to 1/10 power and have lifetimes approximately 10 to 20 times as long, making them ideal for power-saving and reducing replacement work.
Acronym for Light Emitting Diode

Illuminance

This refers to the brightness of the surface illuminated by the light source.
Larger values indicate brighter illumination.
Illuminance values change according to mounting height. The catalog uses measurements at mounting height 0.5 m and 1.0 m for use as guidelines.
Units are measured in lux (lx).

Total Flux

This refers to the amount of light emitted from the light source in all directions.
Larger values indicate a brighter light source.
Units are measured in lumens (lm).

Color Temperature

This is a measure for expressing the color of the light emitting by the light source as quantitative values.
Use it as a guideline for expressing light color matches.
Units are measured in Kelvin (K).

Light Distribution Angle

This refers to the angle at which the light is emitted from the light source.
Larger values indicate a wider illuminated range.
Smaller values indicate a narrower illuminated range, but with higher illuminance.
A light source with a narrow light distribution angle is ideal as a spotlight on tool blade edges.

Illuminance Distribution

This refers to the brightness spread over the surface illuminated by the light source.
Use this as a guideline for brightness spread, bright immediately below the light source and growing darker further away.
It may differ from visual brightness depending on mounting height and use conditions.

Emission Spectrum

This refers to the wavelength components and light strength emitted from the light source.
Refer to emission spectrum data for details.

Lifetime

Unlike incandescent bulbs, LEDs do not fail to light due to broken filaments; however, the quantity of light produced gradually decreases due to deterioration of the materials used, etc.
Lifetime is considered to be the time until the total luminous flux decreases to 70% of the initial total luminous flux.

Color Temperature Figure

The emission spectrum diagram shows the wavelength components and light strength emitted from the light source. Peak wavelength differs according to LED color.
LED lighting does not contain ultraviolet harmful to substances and humans (400 nm or less).
As well, yellow LEDs, with a 595 nm main component optimal for semiconductor manufacturing equipment etc., do not contain wavelength regions of 500 nm or less.
Select the LED colors appropriate to your application.
Note: LED elements have varying color and brightness, causing the emission spectrum to vary to some extent. Use as guidelines (reference values).
