Embodiment 1

[0033] In a lamp with a light direction correction function according to the present invention, since the lamps used in practice have various shapes, the specific structures of the lamp lens and the installation cavity are determined according to the actual situation. As a preferred embodiment, such as figure 2 and image 3 As shown, the lamp lens 2a of the lamp 1a has a flat mounting surface 7, the mounting cavity 3a is a dome-shaped structure raised from the mounting surface, the light source 5 is installed in the center of the mounting cavity 3a, the The mounting plate 6 is installed on the mounting surface 7 , and the reflective plate 4 a is connected to the mounting plate 6 . Preferably, the reflective plate 4 a is detachably connected to the mounting plate 6 . Lamp lens 2a of this structure is often used in street lamps. The so-called dome-shaped structure is a structure with a raised center similar to the inner roof of a yurt. The shape of the inner surface of the mou...

Embodiment 2

[0035] As a preferred embodiment, such as Figure 5 and Figure 6 As shown, the lamp lens 2b of the lamp 1b is a columnar structure extending left and right, the mounting cavity 3b is a columnar cavity extending left and right, and a reflector 4b is provided on the left and right sides of the light source 5 respectively. In this way, the reflectors 4b on the left and right sides of the light source 5 can reflect the light scattered to the left and right sides of the lamp lens 2b to a position close to the middle of the lamp lens 2b, so as to block the light from scattering to the position that does not need to be illuminated. Concentrate on where light is needed. More preferably, the reflectors 4 b on the left and right sides of the light source are arranged symmetrically with respect to the mid-section plane of the light source 5 .

[0036] A lamp with illumination direction correction function of the present invention can be applied in various lamps that need to correct th...

Abstract

The invention relates to a lamp with the lighting direction correction function. According to the lamp with the lighting direction correction function, because a reflector is arranged on one side of alight source, the reflector is used for receiving part of the light rays given out by the light source and reflecting the received light rays to the outer side of a lens. Therefore, the reflector canbe arranged on the side needing no light as needed so that the light rays given out by the light source can be reflected to the side needing light, and then the lighting direction can be corrected; and the requirement for application can be met, and furthermore, the use efficiency of lighting can be improved. Thus it can be seen that the lamp with the lighting direction correction function can correct the lighting direction of itself as needed, and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a lamp with the function of correcting the direction of illumination, in particular to an LED street lamp capable of correcting the direction of illumination. Background technique [0002] Street lamps are used for road lighting, and there are different lighting requirements in different road environments. For example, on secondary roads with many pedestrians and non-motor vehicles, the light emitted by road lamps is required not only to illuminate the road surface, but also to illuminate part of the light. On the sidewalk; and the lighting of the urban elevated expressway, the rear light not only does not serve the lighting service, but also may cause light pollution. [0003] At present, the LED secondary optical lens used for street lighting mainly has two structures: free-form surface lens and total internal reflection. The free-form surface lens is suitable for uniform illumination of the motorway, but it is difficult to ...
