The characteristics of high power LED lamp
Application of high-power LED lamp products, is a multi-disciplinary integration, many factors affect the product, including high-power LED LED lamp performance and participation
Number of industrial design, optical design, thermal design, circuit design, structural design, process technology, production technology and other sectors. In the design and production process must take full account of relevant factors, the deviation of any one link will affect the product performance and effectiveness. 1 is a typical high-power LED LED green lighting products, as the country promoting the use of green lighting products, high-power white LED light source is an inevitable choice. The product features are as follows: ◎ High efficiency: High Power LED luminous efficiency of over 45 lm / W, but also because almost all the spectrum LED concentrated in the visible light spectrum, far more efficient than incandescent light and is catching up with energy-saving lamps and fluorescent lamps. See Figure 1 white LED spectrum, daylight, incandescent, fluorescent spectra shown in Figure 2. ◎ high quality of light: not as ultraviolet and infrared spectra, there is no heat, no radiation, the eye does not give a burden for a long time to read or work will not have sore eyes swollen phenomenon. ◎ color is good: Compared with fluorescent lamps, high power LED lamp with high color rendering index, usually in the 80 or so. This helps to reduce the human eye fatigue, eye protection is very helpful. ◎ Low maintenance costs: LED, long life, luminous flux life of more than 50,000 hours half-life of more than 30 years of normal use. Shock and vibration capability, there is no tungsten wire, glass and other fragile components, non-normal "retirement" is unlikely. ◎ Small size: can make the lamps are compact, more suitable for the use of different places. ◎ cooperation with the battery, it is easy to make emergency lamp light. When the power failure or emergency situations, to help people evacuate and lighting. ◎ Green: Waste recycling and pollution; unlike fluorescent lamps contain mercury components. 2 Power LED driver selection and requirements of different ways, in the products we use low-voltage lamp constant current drive. Constant current drive mode is an ideal way of LED drivers, it can avoid the LED forward voltage changes caused by current changes, while a constant current to LED brightness stability. AC-driven light source commonly used with a stroboscopic effect will be changing the visual nerve stimulation intensity, fatigue, constant current drive of the LED to a steady light, completely flicker-free, thus making a visual feel very comfortable. Lamp with low voltage input for safety, to avoid the general lighting circuit failure caused by accidents. 3 high-performance lighting a good lighting optical system to have high-performance optical system, and high-performance optical reflector is one of the components of technical content. It is highly reflective, well-controlled optical angle and uniformity of reflected light. Through computer simulation to design the lighting of the optical system, making the light emitted from the LED through the reflector and lens and other optical devices to re-allocate, with reasonable light, fully meet the design requirements. Anodized reflector, reflective, high efficiency, durability; mixed with high transmittance of light material of the lens. Optical system that maintains high efficiency, and reduced glare. In study and work as usual to buy lamp lighting equipment, we should pay special attention to the problem of glare lighting, do not let the light line projected onto the eye. A direct result of light projected onto the eyes, the eyes have sensitivity to light and easy sense of fatigue, and restlessness and feeling around the dark, which led to blurred. Long glare lighting environment in which reading, writing, vision will be greatly impaired. With eye health, the first high-quality lighting from the beginning, which requires us to buy more when you pay attention to LED lamp quality. 4 lamp cooling system using cooling is the main factor of LED lamp, high power LED lighting applications in the process of cooling devices and appeared to be very important. We are LED packaging and full design of the second heat, the use of hollow metal with cooling fins and the metal material of the shade body heat, reducing the thermal resistance of LED light source, the overall good thermal characteristics. The overall structure of the 5 best lighting design not only high quality LED, high-quality electrical components, high performance reflector, reasonable structure, but also have a good product design. High Power LED desk lamp product we designed to take full advantage of the features and advantages of high power LED, to meet the practical needs and to maximize the effectiveness of light under the premise of the compact design of the lighting, the fixtures will be designed as small and delicate to the overall for the use of different places. Appearance on the lamps in a beautiful, comfortable, durable and aesthetic results but also to the environment. Lamps used in all metal structure, giving strong and durable and high-end features, reflecting the high-end products, and modern features. As the advantages of LED itself, and high-grade lighting structure, we will high-power LED lamp table lamp is positioned as high-end products, widely used in office and learn. Lamp shape see Figure 3. Energy-saving functions and features ◎ 6: light source power LED, low energy consumption and high efficiency. Power: 3W/4W. ◎ environmental protection: pollution, ultraviolet, infrared and thermal radiation. ◎ Health Eye: The low-voltage constant current power supply, no flicker, no glare, light a wide area, uniform brightness, the visual effect is good. Truly a light and soft, smooth, continuous, close to natural light, is really the ideal source. ◎ durable: LED lamp life of 50,000 hours. Metal structures, metal feel strong, strong and durable. ◎ adequate illumination: light-emitting parts of the lamp from the desktop, under the conditions of 350-400mm, the desktop more than 500 lx illumination can be achieved.
Edit this paragraph the reason LED lamp does not light
First, the LED lamp 1 rechargeable battery damage without electricity, power can not be recharged? 2, the charge line fault? 3, the charge turned on the light, resulting in LED burn out? Second, only the battery LED lamp 1, the printed circuit looks good, but can not see the breaks in? 2, the battery is dead or can not supply (eg, bad) 3, due to excessive current (manufacturers in order to light brighter, the LED's current design is too large, leading to greatly shorten the life of LED, LED dimming is often the situation The process that does not light), resulting in LED burn?
