Abstract
The utility model discloses an LED advertising lamp capable of changing light distribution, which comprises an advertising lamp main body; the advertising lamp main body is internally provided with a plurality of groups of LED lamp groups which comprise condensing lenses and LED circuit boards; the LED circuit boards are provided with a plurality of LED lamp beads; the condensing lenses are arranged on the LED circuit boards and are provided with a plurality of condensing mirrors; the LED lamp beads are arranged below the condensing mirrors; the light gather of the condensing mirrors on the condensing lenses faces to different directions; the light gather of each group of the LED lamp group faces to the outer side with different angles; and within the lighting range of the advertising lamp, the light quantity of the advertising lamp irradiating remotely is larger than the light quantity of the advertising lamp irradiating nearby, so that the lighting luminance remotely is increased.
Description
Technical field
The utility model relates to the advertising lamp technical field, especially relates to a kind of LED advertising lamp that changes distribution of light.
Background technology
In the prior art, the LED advertising lamp is used to billboard illumination is provided, because the LED light fixture has fixing lighting angle, in the illumination zone of advertising lamp, it is less that advertising lamp shines light amount at a distance, and the light amount that shines nearby is more.The deficiency of prior art is: in the illumination zone of advertising lamp, brightness of illumination nearby is higher, and brightness of illumination is on the low side at a distance, and bigger with brightness of illumination difference at a distance nearby, distribution of light is unreasonable, therefore is necessary to improve.
Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model provides a kind of LED advertising lamp that changes distribution of light, and it increases brightness of illumination at a distance, in the illumination zone of advertising lamp, has essentially identical brightness of illumination at a distance and closely far.
To achieve these goals, the technical scheme that the utility model adopted is.
A kind of LED advertising lamp that changes distribution of light comprises the advertising lamp main body, is provided with some groups of LED lamp groups in the advertising lamp main body; LED lamp group comprises light-collecting lens and led circuit plate; The led circuit plate is provided with some LED lamp pearls, and light-collecting lens is arranged on the led circuit plate, and light-collecting lens is provided with some condensers; LED lamp pearl places the below of condenser, and the light-ray condensing direction of the condenser on the light-collecting lens is towards different directions.
The light-ray condensing direction of the condenser on the light-collecting lens of the same LED lamp group of said advertising lamp main body is identical.
The light-ray condensing direction of the condenser on said each LED lamp group light-collecting lens respectively toward the outer side.
Condenser on said each LED lamp group light-collecting lens is arranged at same plane.
Condenser on said each LED lamp group light-collecting lens angle of direction toward the outer side diminishes by from outside to inside order successively.
The bottom of said light-collecting lens be provided with one supply the LED lamp to insert the LED lamp take in the chamber, the top that the LED lamp is taken in the chamber has an optically focused direction adjusting portion, the radius of curvature of optically focused direction adjusting portion is taken in the radius of curvature of the middle and lower part in chamber much smaller than the LED lamp.
After adopting said structure; The utility model is compared the advantage that is had with prior art: in the advertising lamp of the utility model, under the condenser effect of light-collecting lens, each light-ray condensing direction of organizing LED lamp group respectively with different angles toward the outer side; In the illumination zone of advertising lamp; Advertising lamp is radiated at light amount at a distance and is radiated at light amount nearby greater than advertising lamp, increases brightness of illumination at a distance, has essentially identical brightness of illumination at a distance and closely far.

Fig. 5 is the cutaway view in BB cross section among Fig. 3.
Among the figure: 1, advertising lamp main body 2, light-collecting lens 3, condenser 4, optically focused direction adjusting portion.
The specific embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
Embodiment, see that Fig. 1 is to shown in Figure 5: a kind of LED advertising lamp that changes distribution of light comprises advertising lamp main body 1; The foremost of advertising lamp main body 1 is provided with the printing opacity lid, is used to protect each assembly of LED advertising lamp, is provided with some groups of LED lamp groups in the advertising lamp main body 1; LED lamp group comprises light-collecting lens 2 and led circuit plate; The led circuit plate is provided with some LED lamp pearls, and light-collecting lens 2 is arranged on the led circuit plate, and light-collecting lens 2 is provided with some condensers 3; LED lamp pearl places the below of condenser 3, and the light-ray condensing direction of the condenser 3 on the light-collecting lens 2 is towards different directions.
The light-ray condensing direction of the condenser 3 on the light-collecting lens 2 of the same LED lamp group of advertising lamp main body 1 is identical, and the condenser 3 on each LED lamp group light-collecting lens 2 is arranged at same plane.
The light-ray condensing direction of the condenser 3 on each LED lamp group light-collecting lens 2 respectively toward the outer side, the condenser 3 on each LED lamp group light-collecting lens 2 angle of direction toward the outer side diminishes by from outside to inside order successively.
The bottom of light-collecting lens 2 be provided with one supply the LED lamp to insert the LED lamp take in the chamber, the top that the LED lamp is taken in the chamber has an optically focused direction adjusting portion 4, the radius of curvature of optically focused direction adjusting portion 4 is taken in the radius of curvature of the middle and lower part in chamber much smaller than the LED lamp.
In the advertising lamp of the utility model; Under condenser 3 effects of light-collecting lens 2; Each light-ray condensing direction of organizing LED lamp group respectively toward the outer side with different angles, in the illumination zone of advertising lamp, advertising lamp is radiated at light amount at a distance and is radiated at light amount nearby greater than advertising lamp; Increase brightness of illumination at a distance, have essentially identical brightness of illumination at a distance and closely far.
Above content is merely the preferred embodiment of the utility model; For those of ordinary skill in the art; According to the thought of the utility model, the part that on the specific embodiment and range of application, all can change, this description should not be construed as the restriction to the utility model.
