Embodiment 1

[0018] Example 1. as attached figure 1 As shown, it includes a lamp body 1 and LED luminous tubes 2 , and a reflector 3 is installed on each LED luminous tube 2 . Wherein the structure of reflective cup 3 is as attached figure 2 As shown, it is a quadrangular conical shell structure with a narrow top and a wide bottom. The top surface has no cover, the bottom surface is rectangular, and the bottom opening is inclined 30 degrees to the left or right. The LED light-emitting tube 2 is installed on the top surface of the reflector 3. The length direction of the rectangular bottom surface of the reflector 3 extends along the road surface, and the reflected light overlaps with the road surface. In practical applications, according to the needs of use, multiple sets of reflective cups with the bottom opening tilted 30 degrees to the left and the bottom surface tilted 30 degrees to the right can be installed in the same lamp body at the same time, so that the scattered light emitte...

Embodiment 2

[0019] Example 2. It includes a lamp body 1 and LED luminous tubes 2 , and a reflector 3 is installed on each LED luminous tube 2 . Wherein the reflective cup 3 is a quadrangular conical shell structure with a narrow top and a wide bottom, with no cover on the top surface and an opening on the bottom surface inclined 60 degrees to the left or right. In practical applications, according to the needs of use, multiple sets of reflective cups with the bottom opening tilted 60 degrees to the left and the bottom surface tilted 60 degrees to the right can be installed in the same lamp body at the same time, so that the scattered light emitted by the luminous tube 2 can be concentrated and projected at the same time after being reflected. On the road on the left side of the street lamp and the right side of the street lamp, it is also possible to install only multiple sets of reflector cups with the bottom opening inclined 60 degrees to the left in the same lamp body, or only install ...

Embodiment 3

[0020] Example 3. It includes a lamp body 1 and LED luminous tubes 2 , and a reflector 3 is installed on each LED luminous tube 2 . Wherein the reflective cup 3 is a quadrangular conical shell structure with a narrow top and a wide bottom, with no cover on the top surface and an opening on the bottom surface inclined 15 degrees to the left or right. In practical applications, according to the needs of use, multiple sets of reflective cups with the bottom opening tilted 15 degrees to the left and the bottom surface tilted 15 degrees to the right can be installed in the same lamp body at the same time, so that the scattered light emitted by the luminous tube 2 can be concentrated and projected at the same time after being reflected. On the road on the left side of the street lamp and the right side of the street lamp, it is also possible to install only multiple sets of reflector cups with the bottom opening tilted 15 degrees to the left in the same lamp body, or only install mu...

Abstract

The invention discloses an LED road lamp and an illuminating light-regulating method therefor. The LED road lamp comprises a lamp body (1) and an LED luminescent tube (2). A light-reflecting cup (3) is arranged on the LED luminescent tube (2). The light emergent from the LED luminescent tube is reflected by the light-reflecting cup and then focused to the road surface in need of illumination. The LED road lamp has optimum light intensity distribution, thereby broadening the illumination range and increasing the illumination brightness, providing LED light uniformly to light the road surface uniformly, meeting the requirements for road lighting, reducing glare to improve the safety of driving on the road at the same time, and overcoming the problem of light waste in the 'bright-under-lamp' phenomenon of the prior light source.

Description

technical field [0001] The invention relates to a structure of an LED street lamp and a method for adjusting the irradiation light of the LED street lamp. Background technique [0002] LED street lamps have been widely used due to their high luminous efficiency, energy saving (nearly 80% power saving), no need for high voltage, and high safety. Their performance has now surpassed that of commonly used fluorescent lamps. In addition to saving energy, LED street lights also have a much longer service life than traditional light bulbs (up to 80,000 hours or more), and because they do not use mercury, mercury, lead and other harmful substances commonly found in ordinary light bulbs, LED street lights are also more environmentally friendly. However, there are also shortcomings in LED street lights, that is, the lighting angle is small and the light irradiation surface is uneven. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
