Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

as shown in fig. 1 to 3, the present embodiment provides an LED lamp with asymmetric light distribution, including an LED light source 10 and a lamp holder 20, where the LED light source has a plurality of LED lamp modules 11, light emitting surfaces of the LED lamp modules 11 are on the same plane and have the same light emitting direction, and light distribution is obtained in an irradiation area, the LED light source 10 is installed on the lamp holder 20, the lamp holder 20 includes a back plate 21 and a connecting member 22, the LED light source 10 is installed on one surface of the back plate 21, the other surface of the back plate 21 is connected to the connecting member 22, the back plate 21 is used for bearing the LED light source 10, and the connecting member 22 is used for installing the LED lamp with asymmetric light distribution to a corresponding position, so that emitted light is asymmetrically distributed, and illumination is uniform in the angle range for a certain area that needs illumination.

In the shape, the shape of the LED lamp module 11 is a long strip, the LED lamp module can be a module formed by arranging a plurality of LED chips along the length direction of the lamp body, the LED lamp module can be installed and the like through the long strip in a better arrangement, the light efficiency can be increased by controlling the length, and the LED lamp module is applied to different scenes. The mode of a plurality of LED lamp modules is used the flexibility high, and lamps and lanterns suitability is more extensive.

In this embodiment, the connecting member 21 includes a connecting portion and an installation portion, the connecting portion with backplate fixed connection, the installation portion rotatable with the connecting portion are connected, and the installation portion can be used to install it on other mounting structure, that is to say, the connection that connecting portion is relatively fixed is on the backplate, can link together the installation portion with connecting portion pivoted mode to the adjustment of illumination direction position can be realized.

Specifically, the shape of installation department is rectangular shape, the one end or both ends of installation department pass through the axis of rotation with connecting portion connect, realize the adjustment of LED light source towards the position through the axis of rotation respectively at the both ends of installation department in this embodiment, and the installation department of rectangular shape can be buckled and install corresponding position with the cooperation, and rectangular shape also can correspond to change to other appearances certainly, realizes its corresponding function equally.

In this embodiment, the number of the LED lamp modules 11 is three, four or five, which can better satisfy the requirement of illumination.

In order to use more conveniently, be provided with the adaptor on backplate 21, LED lamp module group passes through adaptor detachable installs on the backplate, the adaptor can be buckle or anchor clamps etc. and the deformation and the bounce-back of accessible fastener realize, and its material comprises the plastic material that has certain pliability usually, can block LED lamp module group or clip, carries out embedded connection or locks LED lamp module group, can accomplish the instrument-free dismantlement to make things convenient for the installation and the maintenance work of LED light source.

The existing lighting lamp determines how many lamps are needed by using lighting facilities (such as a high pole, a large equipment cantilever and the like) according to a required light distribution scheme by reasonably calculating the illumination requirement so as to meet the required lighting effect. However, in the updating and upgrading of the existing lighting projects, the lighting facilities usually have large differences and cannot meet the required effect, the expected lighting effect can be realized only by selecting lamps with different light distribution for mixed use, and the construction cost and the maintenance cost are increased.

Correspondingly, the embodiment also provides a lighting lamp, which comprises an installation structure and the asymmetric light distribution LED lamp, wherein the asymmetric light distribution LED lamp is installed on the installation structure, the lighting lamp is only subjected to light distribution by using one-way polarized light, all lamps in all needs of the same place are met, and meanwhile, the lighting power of the lamp can be changed in a mode of increasing or decreasing the light source module, so that the asymmetric light distribution LED lamp has wide applicability and low construction and maintenance cost, can adjust the lighting range along with the difference of lighting facilities, has variable shapes, has excellent application effect on other lighting lamps in the same industry, can be directly fixed on the installation structure (such as an installation hole of a high-pole lamp body, a cantilever of large equipment or an installation surface), and can also be fixed on a required installation position through a building structure.
