Lighting Capacitors Manufacturers

AnHui JuanKuang Electric Co., Ltd. has produced metallized polypropylene film capacitors in Ningguo, Anhui Province, China, since 1995. As Lighting Capacitors Manufacturers, we build power-factor correction capacitors for HID, metal halide, LED and lighting-compensation circuits, with metallized film production, winding, welding, spray coating, assembly and testing carried out inside our own workshops.

A lighting capacitor reduces the reactive power drawn by the luminaire and raises the power factor of the circuit, lowering the current carried through ballasts, wiring and supply panels. Our lamp-use capacitors have been supplied in volumes exceeding 500 million pieces into municipal lighting, stadium lighting and road lighting projects, and the same range is available to luminaire OEMs and project suppliers on an OEM/ODM basis.

Lighting Capacitors We Manufacture

The lighting range sits inside our Metallized Film Capacitors family and is organised by case format, temperature class and compensation duty so that each product maps to a defined luminaire application.

Matching Capacitor Type to the Luminaire

Materials and Construction

Every lighting capacitor is wound from metallized polypropylene film produced on our own metallizing line, which gives us control over film thickness, metallization pattern and the self-healing behaviour that protects the element after a local dielectric breakdown.

• Metallized polypropylene dielectric with self-healing properties and stable performance across the luminaire temperature range.
• Cylinder and oval aluminum cases, selected by the space and mounting method inside the fixture.
• End-face spray coating after winding to bond the metallized layers to the terminals, followed by welding and assembly.
• Terminal and lead configurations confirmed against the ballast wiring, including tab size and spacing.

Our production base covers 53,000 m² of workshops with a 2,000 m² research and testing centre, German metallizing coating equipment and Swiss automatic winding machines.

Specifications We Confirm Before Winding

Capacitor For Led Lights are specified as a working point rather than a single part number. We fix the following values with you before a production run is released, because each one changes the element, case or test regime.

• Capacitance and tolerance derived from lamp wattage, ballast impedance and the target power factor.
• Rated AC voltage and frequency for the supply the luminaire will see, including 50 Hz and 60 Hz markets.
• Temperature class of 100 °C or 110 °C, set by measured ambient inside the fixture rather than the outdoor climate.
• Case format and envelope — cylinder or oval, overall height and diameter or width against the available cavity.
• Terminals, leads and mounting, including bracket type, stud or clamp fixing and cable exit direction.
• Safety construction for compensation products, Class A or Class B mechanical anti-explosion.
• Discharge resistor where the luminaire design requires defined discharge behaviour after switch-off.

Quality Control and Acceptance Evidence

We operate ISO9001 and ISO14001 management systems and hold UL, VDE, CE and CQC certification across the capacitor range, supporting market access in North America and Europe. Our Capacitor For Led Lights have also been recognised through provincial and national new-product programmes, and the company took part in drafting the GB/T 3667.1 national standard for AC motor capacitors.

Production follows a documented sequence from incoming film inspection through winding parameter control, in-line checks, semi-finished testing, finished-product inspection and pre-shipment control. Finished lighting capacitors are inspected 100% against the agreed specification before packing, and automated test stations in our testing centre cover the routine electrical checks on each batch.

Installation, Replacement and Service Life

Lighting capacitors are connected in parallel with the ballast circuit, so correct terminal identification and a sound mechanical fixing matter as much as the rating itself. The notes below reflect the conditions that most often shorten service life in the field.

• Discharge the capacitor through its resistor before handling; never touch terminals on a capacitor removed from a live fixture.
• Keep the case clear of ballast heat sources and leave the ventilation path inside the housing unobstructed.
• Match the replacement to the original capacitance, voltage and temperature class — a lower class raises internal temperature and shortens life.
• Tighten terminal connections to the fixture manufacturer's torque and check for case swelling or discoloration during maintenance.
• On project installations, periodic capacitance checks identify drift before power factor falls below the contractual level.

Information We Use to Configure Your Solution

We prepare a lighting capacitor proposal from the working point, the mechanical envelope and the acceptance requirements of the project. Sending these inputs together shortens the path from enquiry to a confirmed sample.

Frequently Asked Questions

What does a lighting capacitor do inside a luminaire?

It compensates the inductive reactive power of the ballast, raising the power factor of the fixture and reducing the current drawn through supply cables and switchgear. Municipal and road lighting schemes specify it to keep the installation within the power factor required by the network operator.

Which lighting capacitor fits HID and metal halide fixtures?

CBB65 in cylinder aluminum case is the standard choice for HID high-bay, road and flood luminaires, available in 110 °C for restricted ventilation. CBB66A in oval aluminum case serves the same lamp types where the housing is too slim for a cylinder, and the 100 °C versions cover metal halide luminaires with moderate internal temperature.

Can capacitance, case size and terminals be customised?

Yes. Capacitance, voltage, dimensions, terminal arrangement and packaging are all customisable, and we develop parts from customer drawings or samples under OEM and ODM arrangements. Custom work starts from the electrical duty and the mechanical envelope of your fixture.

Which certifications support export orders?

The range is covered by UL, VDE, CE and CQC certification, and the company operates ISO9001 and ISO14001 systems. These certificates support market access in North America, Europe and other regulated markets, and copies are provided with the quotation package.

How is quality controlled on a lighting capacitor order?

Full-process management applies from incoming metallized film inspection to winding parameter control, in-line checks, semi-finished testing and 100% final inspection of finished capacitors before shipment. Test records are retained per batch and can be issued with the delivery documentation.

What is needed to receive a quotation?

Send the capacitance and tolerance, rated voltage and frequency, temperature class, case format with space limits, terminal and mounting requirements, annual volume and any certification or marking needs. Our proposal is based on that working point and states the case dimensions, test scope and packaging for confirmation.
