2. Enhanced Energy Efficiency: Nichia LED modules are known for their high-energy efficiency, converting more electricity into light and less into heat. This efficiency maximizes energy savings and reduces operational costs, making high-quality LEDs a cost-effective choice for signage backlighting.

4. Wayfinding Signs: Wayfinding signs in transportation hubs, hospitals, and large complexes benefit from Nichia LED modules' clear and uniform lighting. This improves the readability and effectiveness of directional information.

Although the unit cost of laser-based illuminators is higher than LED illuminators, their use in appropriate situations can bring significant cost savings. Because of their high efficiency (four to fives times that of LEDs and greater than 20 times that of incandescent illuminators), laser-based systems can put out far more power per unit cost than other systems. For example, a single 40-W illuminator can light up an area of more than 15 acres with excellent image quality using a monochromatic CCD camera with good IR sensitivity. It would require multiple conventional illuminators with individual mounting structures and increased maintenance costs to accomplish the same effect. When portable or remote installations are being considered, the higher efficiencies translate into dramatic reductions in the size and cost of the power sources, whether battery, solar, or other.

2. Indoor Signage: For indoor signage in malls, airports, and other commercial spaces, Nichia LED modules offer efficient and attractive lighting solutions. They enhance the visibility of signs, making it easier for customers to navigate and locate businesses.

Signage backlight lighting refers to the illumination of signs from behind, using light sources to make the displayed content visible, vibrant, and readable both day and night. This type of lighting ensures that signs are eye-catching and can attract attention in various lighting conditions. High-quality backlighting is essential for achieving uniform brightness and color consistency across the entire surface of the sign.

With the introduction of lower-cost thermal cameras, an increasing number of applications may potentially change over to the use of thermal cameras. There are many advantages to thermal imaging for security monitoring and defense-surveillance-related applications. Thermal imaging is totally passive, provides very high contrast (under most environmental conditions), and is effective in detecting intruder movement, even at the limits of the camera's range. However, for the vast security marketplace, installing illuminators is likely more cost-effective and extends existing camera infrastructure and will even improve daytime camera performance under difficult lighting conditions. In addition, visible/near-IR CCD cameras provide higher resolution and mate up with a wide range of low-cost zoom lenses that can capture details such as license-plate numbers, ship and plane registration markings, and identifiable images of people for potential use in criminal prosecutions at ranges from a few meters to 1000 m.

Eye-safety considerationsEye safety of laser devices is determined by comparing the radiation intensity with maximum permissible exposure (MPE) levels. These MPE values are a function of exposure duration, wavelength, and other factors. The limits are determined by extensive testing under the supervision of a number of national and international agencies.The output of a near-IR sheet-optic laser illuminator has been compared to the applicable MPE by a Ford team.3 Using the same methods, the outputs of the Electrophysics illuminators were compared to the MPE and found to be about an order of magnitude below the danger level under the worst conditions (constant staring at about 8 in. from the output surface). This means that they can be classified as Class 1 laser devices that can be used with no restrictions on mounting and handling.Performance benefitsThe high output power of the laser illuminator makes it possible to effectively image at ranges in excess of 1000 m. Specific range performance is determined by a number of factors including the path length, the power of the illuminator, the field of emission of the illuminator beam, the transmissivity of the atmosphere, the IR sensitivity of the camera, the f-number of the lens, and the effective reflectivity of the illuminated object.As described by the inverse-square law, as the luminous flux travels away from the light source, the power of the beam decreases by the square of the distance. The reflected energy is also subject to the same effect, leading to a reduction in effectiveness that decreases roughly as the fourth power of distance. Imaging at such long distances is thus a significant achievement. In comparison, LED-based illuminators typically provide a maximum range of 100 m (see Fig. 2).

The pitch of the LEDs, or the distance between individual LED modules, plays a critical role in achieving uniform, hotspot-free illumination in backlit signage. The optimal LED pitch is closely related to the distance between the LEDs and the sign surface. By finding the right balance between LED pitch and distance, you can ensure smooth, even lighting across the entire sign surface.

The output of a near-IR sheet-optic laser illuminator has been compared to the applicable MPE by a Ford team.3 Using the same methods, the outputs of the Electrophysics illuminators were compared to the MPE and found to be about an order of magnitude below the danger level under the worst conditions (constant staring at about 8 in. from the output surface). This means that they can be classified as Class 1 laser devices that can be used with no restrictions on mounting and handling.

Illuminators operating at 810 nm emit a slight red glow that may be seen under conditions of total darkness and in which the illuminator's diffuser is directly visible. Using an indirect lighting setup will eliminate any observable light signature. For applications requiring totally covert operation, longer-wavelength laser illuminators can be used. Although the laser-illuminator optics will work with lasers over a wide spectrum, the quantum efficiency of CCD cameras falls off significantly as the wavelength approaches 1000 nm. For example, the range performance of a 900-nm laser illuminator/CCD camera setup is reduced to approximately 75% to 80% of the illumination range of an 800-nm system when the scene is in total darkness. In cases in which the illuminator is being used to optimize the illumination of a scene where other light is present, however, there is no reduction in performance because the camera's response to the ambient light is reduced by the same factor. For most public area surveillance monitoring, the need for covert operation is not required.

Increased demand for 24-hour surveillance of public, government, and military areas such as borders, airports, bridges, industrial facilities, ports, military bases, reservoirs, and large public facilities like sports stadiums is placing ever-increasing demands on security-systems professionals. Concerns about leveraging installed camera systems, the impact of light pollution on neighboring areas, and long-term service issues need to be met with reliable solutions that make economic sense. A new class of high-power, eye-safe infrared (IR) laser illuminators is now available that extends the use of low-cost visible cameras into nighttime and low-light operation under a wide range of lighting conditions.

3. Longevity: High-quality Nichia LED modules are designed to last longer, with superior materials and construction that withstand the test of time. This durability means fewer replacements and lower maintenance costs, enhancing the return on investment.

The optimum distance between the LED backlight modules and the sign surface to achieve smooth, hotspot-free illumination can vary based on several factors, including the type of LED modules used, the brightness and beam angle of the LEDs, the material and opacity of the sign surface, and the specific application requirements. However, general guidelines can help determine an effective distance.

4. Sign Surface Material The material and translucency of the sign surface play a critical role in light diffusion. More translucent materials may require LEDs to be positioned further away to avoid seeing individual light points, while more opaque materials can allow closer placement.

Though active-IR illumination systems have been fielded for several years, limitations existed. Infrared illuminators based on light-emitting-diode (LED) bundles are limited to short-range applications. Infrared-filtered incandescent systems suffer from low efficiency and short service life.

The high output power of the laser illuminator makes it possible to effectively image at ranges in excess of 1000 m. Specific range performance is determined by a number of factors including the path length, the power of the illuminator, the field of emission of the illuminator beam, the transmissivity of the atmosphere, the IR sensitivity of the camera, the f-number of the lens, and the effective reflectivity of the illuminated object.

LED modules are the recommended choice for backlighting signs. They consist of an array of LEDs mounted on a circuit board, often combined with optical elements to shape and direct the light. The quality and design of these modules significantly impact the overall performance and reliability of the final product.

Although laser illuminators have previously been used, their applications have been limited in power levels and/or wavelengths because of hazards to the eyes of users and bystanders. The concepts developed for automotive applications overcome this problem by expanding the laser beam to the point at which its power density no longer is in the hazard regime. The beam expansion is carried out by a class of optics called sheet optics, which can be implemented in various ways.1, 2 Concepts based on refraction, reflection, diffraction, and geodesic optical elements have been developed.

Camera and lens selection are important when considering the use of IR illuminators. Today's color cameras are designed to precisely capture irradiance in the visible spectrum between 380 and 760 nm using filters, which limits the cameras' sensitivity to IR light. Security cameras are typically monochromatic since they provide increased resolution, significantly higher low-light sensitivity (typically below 0.001 lux), and spectral response out to 1000 nm. Electrophysics has conducted most of its testing with a charge-coupled-device (CCD) camera with a variety of f1.4 lenses with different focal lengths and an IR 10-nm-bandpass filter centered at 810 nm. The use of the filter minimizes the influence of light sources in the field of view on the camera gain setting while still providing adequate daylight sensitivity.

Technology Integration Group (Carlisle, MA) and Ford Motor Company (Dearborn, MI) developed an IR laser illuminator for automotive night vision using an 808-nm-emitting laser diode integrated with a thin-sheet optic and holographic diffuser. The Office of Naval Research (Arlington, MA) and Qualume (Alton, NH) carried out development of IR illuminators for nonautomotive applications in 2002. These developments led to illuminators now being commercially produced by Electrophysics that contain a sealed laser diode and potted electronics for outdoor use and operate at power levels of 5, 20, or 40 W. Advances in optics resulted in a reduction in size; for example, a 40-W version with beam patterns between 10° and 80° has a light-source aperture of less than 80 sq in.

1. Outdoor Signage: Nichia LED modules are ideal for outdoor signage, providing bright and uniform illumination that enhances the visibility and impact of signs. Their reliability and durability ensure consistent performance in all weather conditions.

There are a significant number of advantages to using IR illuminators in security monitoring systems. The ability to see in total darkness is obvious; however, video security scenarios typically include light sources, which potentially impact the effectiveness of closed-circuit-camera performance. Illuminators provide even light throughout the beam pattern, eliminating shadows or areas adjacent to bright light sources where someone might go undetected within the blooming artifact of the camera. Most camera systems use some type of automatic gain control (AGC), which may not provide optimal image quality under lighting conditions typically found in areas monitored by camera systems. Any location where lighting levels are uneven—such as under the decks of bridges, parking lots, or tunnels—can be effectively illuminated 24 hours a day using laser illumination (see photo at top of this page).

5. Environmental Impact: Quality Nichia LED modules are manufactured using environmentally friendly processes and materials. By opting for high-quality LED modules, manufacturers contribute to sustainability efforts, reducing waste and minimizing the environmental footprint of their products.
