Where is the tungsten halogen lamp used? It should be used in places with high illumination requirements, good color rendering or dimming, such as gymnasiums, town halls, and banquet halls. Its color temperature is especially suitable for studio lighting of color TVs. Due to its high operating temperature, it is not suitable for dusty, flammable, explosive, corrosive environment, and places with vibration. Quartz concentrating tungsten halogen lamps are used in spotlights or returnlights for film, television and stage lighting.
The lighting is frequently opened and closed, it needs to be quickly lit, and it needs dimming or avoiding high-frequency interference to the test equipment and shielding room.
Tungsten halogen lamps should be used in places where correct color recognition, high illumination requirements, or long-term intense vision work are required.
Halogen Lamps - Halogen Lamps Advantages and Disadvantages Halogen lamps have a small size
High luminous efficiency (up to 17-33 lm/W)
Color temperature is stable (can choose 2500K-3500K)
Low light decay (less than 5%)
Long life (up to 3000 hours to 5000 hours), etc.
These characteristics show that it has a tendency to replace ordinary incandescent lamps. But quartz glass is expensive, and the price of halogen lamps is certainly higher than incandescent lamps.
Like incandescent lamps, tungsten halogen lamps can be divided into many categories depending on the application, structure and shape.
Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.
Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
Angle Valves, Angle Globe Valves, Brass Angle Valve, Zinc Angle Valve
