Explosion-proof LED lighting (LZWA series)

The first domestic industry product with international explosion-proof certification, also obtained explosion-proof testing standards from Europe and China.

New Release of Explosion-Proof LED Lighting (LZWA Series) Seiwa Electric Co., Ltd. is launching the explosion-proof LED lighting fixtures (LZWA series) as a new lineup in the <STARLED★S> series, which will be the first internationally certified explosion-proof product in the domestic industry for base lighting fixtures. The explosion-proof LED lighting fixtures (LZWA series) aim for a compact and lightweight design while ensuring the same illuminance and light distribution as conventional fluorescent fixtures (HF fluorescent 45W x 2 lamps). With dimensions of less than 30 cm in both width and height, and a weight of only 5 kg, this design reduces the burden of installation work and improves safety due to the smaller contact area. As for explosion-proof standards, it has obtained international explosion-proof certification IECEx (IEC60079-0, -1), as well as European explosion-proof certification ATEX (LZWA12041). Models with Chinese explosion-proof certification NEPSI (LZWA14041-CA) are also included in the lineup, achieving numerous international standards (*). * This product is sold only for overseas markets. Domestic explosion-proof certification has not been obtained.

Underpass Flood Warning Display System

Guerrilla rainstorm countermeasure equipment displays flooding information linked to water level sensors.

The flood warning display system for the underpass at Hoshi and Denki is as follows: ○ Flood display linked with water level sensors - By setting the water level, it automatically displays warnings such as "Flood Caution" and "No Entry Due to Flooding," and activates a xenon light to promptly alert underpass users. - The water level sensors allow for real-time monitoring of flood information (water level) in the underpass. ○ E-rule reporting to road administrators (flood information and equipment monitoring) - Using an internet connection, flood information and equipment monitoring information are sent to administrators via email. - Even if the communication system is disrupted due to disasters or power outages, flood warnings can still be issued based on the set water level. Upon recovery, all monitoring information will be sent via email.

Tunnel lighting LED entrance lighting (with initial luminous flux correction function)

Developed high-capacity, high-efficiency tunnel entrance lighting using white LEDs as the light source, achieving whitening similar to existing ceramic metal halide lamps.

By adopting long-life, high-efficiency white LEDs as the light source and incorporating an initial luminous flux correction function, we achieve low maintenance and energy-saving properties. ○ It can reduce power consumption and CO2 emissions. ○ Maintenance work that requires traffic regulation can be minimized. Maintenance tasks that involve traffic regulation, such as lamp replacement, can be reduced. 1. Long lifespan: 20 years, with only one replacement of the LED and control device, lifespan of 75,000 hours. The LED module has a long lifespan of 75,000 hours, allowing for maintenance-free operation for over 20 years with 10 hours of daily (daytime) lighting. 2. Lineup: Available in four types of light source capacities (80W, 160W, 240W, 320W), covering brightness equivalent to existing HID light sources (CMT, NHT, etc.). 3. Initial luminous flux correction function: A timer-based system is used for initial luminous flux correction to adjust for excessive initial luminous flux.

What are the key points to enhance the energy-saving effects of lighting fixtures?

The most reliable way to save electricity is to "turn off the original switch," but ensuring the necessary illumination is important!

The most reliable way to save electricity is to "turn off the original switch." However, it is important to ensure that the necessary illumination is maintained. 【Fluorescent Lamp Lighting Methods】 ■ Starter Type ■ Rapid Start Type ■ Inverter Type When reducing the number of fluorescent lamps in multi-lamp fixtures, for fixtures using two or more lamps, be sure to remove them in pairs. (For three lamps, remove two and one; for four lamps, remove two at a time as one set.) *For more details, please contact us or download the catalog to view.

Lighting fixtures that have been in use for 10 years have an increased risk of failure. The deterioration of lighting fixtures is not visible from their appearance. Fixtures that have been used for 10 years need to be replaced. If you are experiencing an increase in failures, if dirt cannot be removed even after cleaning, or if the socket is discolored, there is a risk of smoke-related accidents, so please consider replacing them early for safety reasons. 【Safety Check Sheet (Excerpt)】 ■ The usage period is over 10 years. ■ There are deformations, looseness, or instability at the fixture mounting part. ■ There are blisters, cracks, or rust on the painted surface. *For more details, please contact us or download the catalog to view.

Waterproof connector (SCHR type) cable gland

Cable entry point with SC lock! The SCHR type is heat-resistant.

Cable Connector, Heat-Resistant Type, SCHR Type ■ While conventional products have a maximum operating temperature of 80°C, this product can be used at temperatures up to 200°C. (Continuous use at 120°C) ■ If a metal component is used in applications requiring heat resistance, this product can serve as a substitute for metal cable glands. ■ Compared to metal cable glands of nearly the same size, the product weight is reduced by about half. ○ Like the conventional series, it ensures an IP67 waterproof structure. ○ It uses PPS (Polyphenylene Sulfide) resin, which has excellent heat and oil resistance. ○ It contains glass fibers, resulting in a rough surface texture. ● Lead-free ● RoHS compliant ● Halogen-free
