In terms of optical design of LED lighting fixtures, compared with traditional lighting fixtures, directional and point light sources are the most typical characteristics of LEDs and the key to the optical design of lighting fixtures. Through the dual optical design of LED, LED lamps can achieve a better light distribution curve. Just as the light of indoor lighting, which is currently the largest in the development and application market of LED lighting fixtures, needs to be very bright, a high light transmittance lampshade can be used to improve the light extraction efficiency. Or the light guide plate technology is applied to the lamps, and the LED lighting changes the LED point light source into a surface light source, which can not only improve the light distribution uniformity of the lamps, but also prevent glare. It can also be used with some condensing lenses or reflectors to highlight the condensing effect of illuminated objects to achieve ideal optical effects.
Technical challenges of high-power LED lighting, even though LEDs have performed satisfactorily in indoor accent lighting and decorative lighting applications, there are still many challenges in general lighting and ambient lighting applications, including initial cost, low color temperature of light efficiency, color rendering index and system reliability. Cost is a relatively sensitive factor in indoor lighting, especially in home lighting applications. Although there are more and more types of LED lamps and the luminous efficiency is constantly improving, the problem of high price still exists. However, when the price of LED light sources is reduced and the overall system design is optimized, the total cost will inevitably decrease.
LED lamps improve light efficiency at low color temperature. Low color temperature below 4,000K is usually the first choice for indoor home lighting. Warm white light makes the whole environment more warm and relaxing; while cool white light gives a clean, efficient and bright feeling, which is more suitable for office and outdoor lighting. Extend the service life of LED lamps and improve system reliability. In general lighting applications, the overall efficiency, lifetime and reliability of LEDs must be improved through system optimization. LED light source: compact, efficient and available in a variety of colors and output power. Power Conversion: Efficiently convert alternating current, batteries and other power sources into safe low voltage, constant current power sources. Control and Drive: Use electronic circuits to achieve constant current drive and control of LEDs. Thermal Management: Controlling the temperature of the LED node is very important to achieve a longer lifetime, and thermal analysis is also essential. Optical Elements: Lenses, reflectors or light guide materials are the optical elements necessary to focus light on the target area.
With the rapid development of LED technology and the gradual improvement of LED light efficiency, the application of LED lighting will become more and more extensive; especially with the increasingly serious global energy shortage problem, people are paying more and more attention to the development prospects of LED in the lighting market , LED will be a potential light source to replace incandescent, tungsten and fluorescent lamps. In addition, in terms of interior lighting design, LED will tend to be energy-saving, humanized and artistic.
