Embodiment Construction
[0023] Such as figure 1 An antique palace lamp for road lighting is shown, including an antique palace lamp housing (1), an LED bulb lamp (3) is installed at the upper end of the housing, and a high-power LED street lamp (2) is installed at the bottom of the housing .
[0024] The structure of the high-power LED street lamp (2) is as follows figure 2 Shown in order from top to bottom includes: LED drive power supply 24, heat sink 21, high-power LED light source 22, LED circuit board 23, light reflector 25, transparent cover 26, silicone sealing ring 27, lamp fixing panel 28.
[0025] figure 2 There are four LED light reflectors in total, and each light reflector is used as an independent unit to distribute light independently, forming a fixed strip-shaped irradiation area on the illuminated road surface. The power of lamps, the number and arrangement of reflectors can be determined according to the customer's requirements for illumination. The length-to-width ratio of th...

The invention discloses an optical reflector for a road-lighting LED antique-modeled palace lantern. The optical reflector is mainly of a slot structure. The reflecting faces of the optical reflector include a main reflecting face and a auxiliary reflecting face. The main reflecting face comprises a front wall reflecting face and a rear wall reflecting face. A front wall stretching bus is straight and form a 35-degree included angle with a light source positioning hole axis. A rear wall stretching bus is a composite secondary curve which includes 12 straight lines. The front six straight lines and the rear six straight lines are in mirror symmetry. The included angle between the first straight line and the light source positioning hole axis is 3 degrees, the included angle between the second straight line and the light source positioning hole axis is 8 degrees, and the included angle between each of the fourth, the fifth and the sixth straight line and the light source positioning hole axis is 75 degrees. The optical reflector adopting non-imaging optics and a polarized reflecting structure has the advantages that the contour of the reflecting mirror faces are designed into column faces formed by the composite secondary curves and a plurality of slopes, light distribution curves of the lantern is polarized towards road width by 20-25 degrees, and the lantern elevation angle problem is solved effectively.
Description
technical field [0001] The invention belongs to the field of LED lighting, in particular to a light reflector of an LED lamp. Background technique [0002] Antique palace lanterns have a history of thousands of years in China and have become a symbol of Chinese traditional culture. Antique palace lanterns are special handicrafts made by handicrafts in my country. In ancient times, candles could only be used as light sources, so they could only play a decorative role in some luxurious palaces and residences. Due to the emergence of electric lights in modern times, classical palace lanterns are also used as street decoration and road lighting on the streets of some historical and cultural ancient cities. Commonly used light sources include incandescent lamps and fluorescent lamps. The structural material of the lamp body has also developed from the ancient wooden frame and gauze to today's steel frame and plexiglass mask, which is strong and durable. [0003] At present, th...
