This year, the market demand for LED garden lamp manufacturers is very large, and it has replaced the traditional garden lights. However, many people have found that LED garden lights have a series of technical problems. Need to understand, today my company explains in detail how to make LED garden lights brighter. Everyone knows that LED is to adjust the lighting effect according to the control light angle. In other words, the light angle is a big factor that determines the brightness of the LED. The general cell or garden light is 3.5 meters or 4 meters. According to the geometric two solution relationship, A general angle of illumination of 140 degrees is calculated as a good angle.
In order to improve the utilization of street lamps in road lighting, the center of the illuminating light intensity of the luminaire is inclined at a certain angle to the road direction. Ideally, the center of the light intensity falls on the center line of the road. Considering that the street light fixture itself will have about 10 in the horizontal direction. The elevation angle can be calculated according to the geometric two-angle relationship. ~20. . The lens is mounted on an LED bracket that holds a high power LED chip. The surface of the lens may be coated with an anti-reflection film, and the cavity between the lens and the chip is potted with a high temperature resistant silicone to reduce the multiple reflection of the light in the cavity and directly refract through the lens.
This lens acts as a polarizing light for conventional LED lenses, which is equivalent to the integration of a secondary optical lens with a primary lens. A large feature of LED garden lights for lighting is the directional emission characteristics, since high power LEDs are equipped with reflectors, and the efficiency of such reflectors is significantly higher than that of luminaire reflectors. In addition, the efficiency of the self-reflector has been included in the LED efficacy detection.
The use of garden lights should take advantage of the directional emission characteristics of LEDs as much as possible, so that each LED in the road luminaire directly directs the light to each area of the road surface to be illuminated, and then uses the auxiliary light distribution of the luminaire reflector to achieve reasonable Integrated light distribution. It should be said that the road lamps should meet the illuminance and illuminance uniformity requirements of CJJ 45--2006 and CIE 31 and CIE 115 standards, and the lamp should contain 3 times of light distribution. An LED with a reflector and a reasonable beam output angle has a good primary light distribution. In the luminaire, a good secondary secondary light distribution function can be realized by designing the mounting position of each I, ED and the direction of the emitted light according to the height of the street lamp and the width of the road surface.
The price of the European garden lamp mentioned in the market refers to a kind of garden lamp whose design style adopts some European art elements of European countries and abstract expressions. Such as the common crown garden lights. Its design concept is unique, the European courtyard can basically be said to be a regular classical courtyard, it is very solemn and majestic, and contains a wealth of imagination. Its origins can be traced back to the Roman era. At the time, the courtyard designed by the French and the Italians was famous for its return to the classical horn. Although France and Italy are different, the similarities between them are obvious. Manicured shrubs and memorial fountains are the main elements of this type of garden: in addition, the garden still has enough space to build some decorations, such as the sundial, the gods, the pedestal for the birds, the flowers and plants, etc. It is also one of the markers.
