Engineered for extreme environments, delivering high luminous efficacy, robust IP protection, and customized optics for global installations.
In the rapidly transforming solid-state lighting (SSL) industry, global B2B buyers—ranging from electrical engineering firms and distribution conglomerates to architectural specifiers—face the critical task of choosing the right partners. It is no longer just about procuring hardware; it is about establishing a highly integrated OEM/ODM partnership that can manage thermal dissipation, maximize lumen-per-watt efficiency, customize optical distributions, and ensure global compliance.

A reliable OEM/ODM process relies on advanced hardware and strict manufacturing controls. Zhejiang Lili Light Co., Ltd. has built an integrated production system that runs from raw Surface Mount Technology (SMT) assembly to simulated environmental testing and automated packaging. By keeping these critical processes in-house, we maintain full control over quality and minimize defects.
In mature markets, commodity lighting products often struggle with fast lumen depreciation, premature driver failure, and poor color consistency. To counter these issues, we focus our custom LED projector engineering on four key technical principles:
The lifetime of an LED chip is directly tied to its junction temperature ($T_j$). If heat builds up, the luminous output drops and color shifts occur. We address this by using copper-clad, metal-core printed circuit boards (MCPCBs) along with 6063-T5 die-cast aluminum heat sinks. These heat sinks feature optimized cooling fin layouts that maximize airflow, keeping the junction temperature well below 75°C when operating at a 25°C ambient temperature. This ensures our projectors maintain their L70 rating for over 50,000 hours.
Depending on the application, LED projectors require specific light distributions. Our engineering team designs custom PMMA and polycarbonate lenses with light transmission rates exceeding 93%. We offer various symmetric and asymmetric beam angles (ranging from narrow 15° spot lights to 120° flood patterns). These lenses minimize stray light and glare while maximizing lux levels within target areas, making them ideal for architectural facades and industrial projects.
The driver is often the first component to fail in an LED system. We equip our systems with constant-current drivers featuring active Power Factor Correction (PFC > 0.95) and low total harmonic distortion (THD < 10%). Our drivers also include built-in surge protection (typically 4kV to 10kV) to safeguard the light from voltage fluctuations in industrial and outdoor settings.
China is the global center for LED lighting manufacturing, housing a highly integrated supply chain ecosystem. Partnering with a manufacturer like Zhejiang Lili Light Co., Ltd. in Zhejiang offers clear strategic advantages:
We modify mechanical, electrical, and optical properties to match the exact requirements of your target market.
Custom drivers configured for regional electrical standards, including universal 90-305V inputs, 347-480V high-voltage systems, and 12V/24V/48V DC inputs for solar networks.
Design of custom lens matrices to achieve specific spot, medium, flood, or oval light distributions. Perfect for architectural highlights and targeted industrial illumination.
We apply robust protective finishes, use marine-grade anti-corrosive coatings, and utilize high-grade silicone gaskets. This guarantees dustproof and waterproof performance in IP65, IP66, and IP67 environments.
B2B lighting buyers operate in a strict regulatory landscape. Importing LED light projectors requires verification of certifications that vary by region. At Zhejiang Lili Light Co., Ltd., we build compliance directly into our engineering and manufacturing processes.
For European Union projects, products must meet CE Directives (specifically the Low Voltage Directive 2014/35/EU and electromagnetic compatibility directive 2014/30/EU). Additionally, compliance with RoHS (Restriction of Hazardous Substances) is required to verify the absence of lead, mercury, and other toxic chemicals. Our materials are fully pre-screened to ensure smooth entry into the EU and Middle Eastern markets.
North American projects demand listing under safety standards like UL 1598 (for luminaires) or UL 8750 (for light-emitting diode equipment). Additionally, commercial projects often require energy efficiency approval from the DLC (DesignLights Consortium) to qualify for utility rebates. We work closely with leading labs to secure UL/ETL listings and DLC qualifications for our OEM partners.
Outdoor floodlights, vapor-tight fixtures, and park wall sconces need reliable ingress protection. We design our housings to meet IP65, IP66, or IP67 standards. They undergo pressurized water-jet tests to ensure dust, humidity, and rain cannot bypass the silicone sealing systems and damage the internal electronics.
The global LED projector market is evolving rapidly, driven by two main technological shifts:
Standard on-off lights are shifting toward smart systems. Modern installations rely on 0-10V analog dimming, DALI-2 (Digital Addressable Lighting Interface), and wireless protocols like Zigbee, Bluetooth Mesh, and Tuya. Our engineering team designs custom driver compartments that accommodate RF modules and smart sensors, allowing fixtures to dim, harvest daylight, and integrate into central building management systems.
In municipal and remote settings, grid power can be expensive or unavailable. Combining LED technology with high-efficiency solar cells, MPPT (Maximum Power Point Tracking) controllers, and LiFePO4 batteries is now a key trend. Our solar street lights and anti-vandal solar wall lights are designed to optimize power consumption, providing steady light output even during multi-day periods of overcast weather.

For new custom designs, the optical and thermal simulation takes 7 to 14 working days. Once the 3D drawings are approved, tooling and prototyping require another 25 to 30 days. Mass production is typically completed within 30 to 45 days after prototype sign-off.
We purchase chips from single-bin selections and maintain color consistency within a 3-step or 5-step MacAdam Ellipse (SDCM < 3 or SDCM < 5 depending on customer requirements). This prevents visible color variations across multi-fixture installations.
Yes. We offer standard finishes in black, white, and grey, and can apply custom RAL colors. For coastal or highly corrosive environments, we use marine-grade anodization and specialized powder coatings.
Every production batch undergoes a 100% burn-in aging test. We run the fixtures continuously for 24 to 48 hours at elevated temperatures, performing rapid on-off switching to identify potential driver or chip failures before packaging.
We offer standard warranties of 3 to 5 years. In the rare event of a component failure, we request operating data, photo diagnostics, and occasionally the return of the failed part for analysis. We then provide replacement drivers, LED boards, or complete fixtures.
Yes, we work with testing laboratories such as TÜV, SGS, and Intertek to help our clients secure CE, RoHS, UL, or ETL listings for their customized fixtures.
