Confirm the specifications of the luminaire before installing the luminaire. (1) Confirm that the specified voltage of the luminaire matches the power supply voltage. For example, a 110V luminaire uses 220V voltage, which will burn the built-in ballast. (2) Fluorescent lamp HID lamps use the specified voltage within the allowable range
A) The power supply and voltage are too high, which will reduce the life of the ballast and the lamp.
B) The power supply and voltage are too low, which will make the bulb not light or reduce the life. Lamp allowable voltage range
Fluorescent lamp + - less than 6%
HID lamps + - 6% or less (but within + -5% when using metal lamps)
2. Confirmation of selected lamps
The choice of lamps for various places, the place of use and the applicable lamps. Environmentally applicable lighting environment
Rain-proof places (rises on the eaves, wind and rain outside the house) Rain-proof lamps that produce flammable gases (oil, chemical plants) pressure-proof explosion-proof lamps
Moisture-proof lamps (bathrooms, basements, underpasses, etc.) Corrosion-resistant lamps (chemical plants, hot springs) Corrosion-resistant lamps
A low-temperature place (freezer, etc.), a place where the lamps in the freezer are shaken (factory, gymnasium, etc.)
For places with moisture and moisture outside the bathroom, please use waterproof lamps. Waterproof lamps can be divided into (moisture-proof) (rain-proof) and (rain-proof and moisture-proof) depending on the waterproof performance. When using, please choose suitable for use. The luminaires of the place. ‧In the wet and wet places such as eaves and house side passages, the lamps are poorly insulated due to humidity, and the reflectors are rusted. Please use moisture-proof and rain-proof lamps.
III. About the installation of lamps
A) The installation distance between the luminaire and the luminaire should not be too close. When the luminaire is installed too densely, the temperature of the luminaire will increase.
B) If the temperature of the lamp is too high, the temperature rise of the ballast will exceed the allowable range, resulting in shortened life of the ballast and the bulb, burning and the cracking of the lamp holder or the internal space of the lamp.
C) The factors that increase the temperature of the luminaire are affected by the internal space of the luminaire, the size of the luminaire and the luminaire, as well as the construction and materials. Please refer to the following correct installation methods:
(1) Appropriate fixture installation intervals.
(2) Increase the internal space of the lamp.
(3) A heat dissipation hole is provided around the lamp body.
(4) The ballast is not placed.
(5) The interior of the ceiling is well ventilated. D) Fix the installation position of the lamp to avoid contact with flammable objects such as curtains.
E) The upper temperature of gas appliances is very high, and the lamps should be kept at an appropriate distance from the heat source. For example, in the kitchen, the installation position of the lamps should be more than 1 meter away from the heat source.
F) The installation direction of the rainproof luminaires has a specified direction and must be installed in the specified direction to prevent rainwater from entering.
G) When installing moisture-proof and rain-proof luminaires, the following points should be noted:
(1) The rubber gasket on the mounting surface and the lamp mounting part must be tight.
(2) If there is unevenness on the mounting surface, fill the circumference of the lamp mounting position and install the lamp.
(3) Pay attention to whether the outlet of the power supply lead is immersed in water.
H) When the reinforced concrete surface device is used, the concrete surface must be dried before the luminaire can be installed. If the luminaire is not confirmed to be dry, the moisture of the concrete will be absorbed by the luminaire after the installation of the luminaire, resulting in lower insulation and lamp coating. Surface shedding.
Precision Optical Flats are ideal for a variety of applications including interferometry, imaging systems, laser applications, optical path folding, and autocollimation. These mirrors are available in a variety of coating and substrate options, along with surface flatness options of λ/10 and λ/20. Fused Silica, is optically clear and features excellent resistance to abrasion and high durability, making it the best choice for applications in harsh environments.
Silicon features a Knoop Hardness of 1150 and low density, making it tougher than germanium substrates and suitable for weight-sensitive applications, respectively. Diamond-Like Carbon (DLC) Coated Silicon Windows are engineered for 3 to 5µm, making them ideal for infrared defense applications such as thermal imaging.
Diamond-Like Carbon (DLC) Coated Silicon Windows provide anti-reflection coating on one surface and a specially designed DLC coating on the other surface, making these windows highly durable and ideal for harsh environments.
