Longman Photoelectric Stage and Entertainment Product Line Introduction
Longman's brand theme is "Shaping Stunning Visuals with True Colors and Smart Lighting." The product line includes:
- Moving Head Color Series: Utilizes LED four-in-one RGBW light sources, meeting both regular and zoom angle requirements. Features limitless rotation technology for broader applications, covering professional stages and bars.
- Moving Head Pattern Series: Primarily uses a 150W LED light source, replacing traditional 250W pattern lights and competing with 575W moving head pattern lights.
- Moving Head Beam Series: Employs short-arc discharge light sources like 2R/5R/15R, achieving angles within 4 degrees. Axial luminous intensity exceeds 2 million cd, combining pattern light functionality.
- Auditorium Series: Uses high-color rendering light sources with Ra>90, R9>50, offering soft focus, color temperature adjustment, catering to large area illumination and specific focal lighting.
- Battery and Wireless Professional Rental Series: Meets needs in places inconvenient for power and signal wires. Uses 2.4GHz WIFI, compatible with LM-DMXA1 and W-DMX systems, providing wireless control for a full 10 hours at full load.
- Matrix Background and Audience Light Series: Suits stage backgrounds, backlighting, and high axial luminous intensity screen effects. Compatible with Artnet system, introducing variable white light screens for playing colorful and variable white light videos on a single screen.
- Commercial Color Series: Includes embedded installed spotlights, track lights, pendant lights, and high-ceiling installations. DMX system controlled, offering vibrant colors, variable color temperature, meeting a wide range of color needs.
- Indoor PAR Light Series: Covers RGBAWUV full-color range with high saturation and fluorescent effects. Incorporates white light for a continuous spectrum, adding amber to achieve light colors similar to tungsten lamps. Uses direct heat dissipation housing, avoiding noise, suitable for noise-controlled environments like music halls.
- Indoor Professional Color Light: Meets internal frame lighting, floor and ceiling lighting, and large-area color output requirements.
- Outdoor PAR Light: Meets IP66 protection level for outdoor performance in beam and color. Features zoom functionality for different height stage rental performances, using stainless steel large tension lock for various harsh operations during rental assembly.
- Outdoor Professional Color Light: Equipped with a breathable valve, keeping the glass surface free from oil mist, maintaining brightness without attenuation. No black zones in close-range wall washing, and no color aliasing.
- Private Room Lighting Series: Outputs patterns, lasers, various gradients, chasing colors, flashing, and effects beams in a mini size.
Longman holds multiple appearance patents, utility model patents, and three invention patents, including various nonlinear imaging optical patents, linear imaging optical patents, and product structure design patents.
All Longman series comply with the Chinese standard "WH/T 32—2008 DMX512-A" and the global standard "E1.11 - 2004 USITT DMX512-A." They support 2.4GHz WIFI control, expandable to global industry protocols like Artnet and RDM, and backward compatible with controllable silicon dimming.
Longman products feature five dimming curves (Dim0-Dim4), including advanced DIM4 power function smooth curve dimming technology and HIS dimming mode favored by lighting designers.
Optically, Longman provides products with colors from 380nm UV to 660nm deep red and white light in the range of 1700-10000K. Strictly controlled parameters include BIN for white light, high Ra, R9 values, and SDCM<5 color deviation between multiple batches. Multi-chip LEDs, such as three-in-one, four-in-one, five-in-one, and six-in-one, ensure uniform color mixing inside the lens, enhancing the beauty of the light output surface.
For beam shaping, Longman uses free-form lenses, PMMA lenses, aluminum reflectors, K9 plano-convex mirrors, and other optical components, providing extremely uniform beam shaping. The color standard deviation of the beam is less than 0.005 SDC, offering first and second-generation color-changing zooms from 8-52 degrees and linear imaging zooms from 12-40 degrees. Special beam shaping includes narrow-angle 1.5-degree beams, square beams of 1515 degrees, elliptical beams of 6015 degrees, and 120*10 degrees.
Longman focuses on independent design of appearance and structure, offering more than 20 die-casting molds and 20 stretching molds. All products are durable, passing IR infrared imaging tests and aging tests under full load heat dissipation. Various surface processes are customizable, and IP65, IP66 lamps undergo spray tests before leaving the factory to ensure waterproof performance.
Longman uses automated welding lines, mainly using pick-and-place machines and low-temperature reflow soldering, with wave soldering as auxiliary. This setup accommodates large-scale production without LED thermal conductivity issues. It meets the high-precision welding of 64-pin MCUs, well-executed welding of mainboards, constant current drive boards, and display boards. It uses professional-grade constant current ICs, with a refresh rate greater than 1500Hz, eliminating flickering for camera applications.
Longman employs well-known brand switch power supplies, complying with safety regulations in various countries. They withstand high voltage shocks and rapid full-load and no-load flicker switching at 20 times per second. All products pass basic certifications such as CE, Rohs, and several products pass UL153, ETL1573, and CQC certifications.
Longman's products consider construction needs, featuring a display DMX signal function for easy circuit debugging. Some products have an automatic DMX address allocation function, reducing on-site debugging workload. The display screen also automatically turns off after 2 minutes of inactivity, ensuring darker stage ceilings and better-hidden lights.
Longman has established a global design support center, providing comprehensive, innovative, and reliable solution support throughout the project cycle for design and engineering companies. Longman will continue to work tirelessly with colleagues from all walks of life to create beauty with light.
