Abstract
The utility model discloses an LED (light emitting diode) high-pole lamp. The LED high-pole lamp comprises a substrate for supporting LED light sources, and conducting electricity and heat; a plurality of LED light sources arranged on the substrate; and a secondary lens, wherein the substrate is divided into an upper region and a lower region; and the secondary lens is arranged on the upper region and used for subjecting the LED light sources to secondary optical distribution so as to control the beam angle of the LED light sources. The LED high-pole lamp has the advantages of long-distance projection and short-distance uniform irradiation in the illumination application by using the secondary lens for regional beam control of the LED light sources, thereby realizing long-distance projection of a narrow-angle high-pole lamp and obviating the occurrence of dark areas near the lamp pole.
Description
Technical field
The utility model relates to a kind of lighting, and specifically a kind of LED High-Pole Lamp belongs to field of illuminating lamps.
Background technology
Existing LED High-Pole Lamp limits its beam angle through Beam Control, is 90 degree, 60 degree, 30 degree, 15 degree etc. like beam angle, thereby makes High-Pole Lamp satisfy the requirement of flood lighting.Dark beam angle according to the type High-Pole Lamp is less, is generally 30 degree or 15 degree, and this is in order to reach the requirement of farther distance projection; Wide beam angle according to the type High-Pole Lamp is bigger, is generally 60 degree or 90 degree, mainly is in order to satisfy the illumination requirement of lamp stand near zone.Under the condition of comparable applications environment and lamp installation mode; Dark far away according to type High-Pole Lamp projection distance; But its defective is lower at lamp stand near zone brightness value, and it is higher extensively to shine the brightness value of lamp stand near zone of type High-Pole Lamp, but defective be projection distance not as good as dark according to the type High-Pole Lamp; Therefore, existing LED High-Pole Lamp still can not be realized projection and closely uniform irradiation at a distance.
The utility model content
In order to address the above problem; The utility model has designed a kind of LED High-Pole Lamp, and this High-Pole Lamp is used secondary lens, and Beam Control is carried out in the led light source subregion; Take into account the remote projection and the characteristics of uniform irradiation closely, not only can throw at a distance but also uniform irradiation closely.
The technical scheme of the utility model is:
A kind of LED High-Pole Lamp comprises: substrate, be used for support, conduction and heat conduction to led light source, and said substrate is provided with some led light sources;
Described substrate is divided into two zones up and down, and upper area is provided with secondary lens, and said secondary lens is used for carrying out the secondary optics luminous intensity distribution to led light source, controls its beam angle.
Further, the beam angle of the led light source of described substrate lower area is 60 degree; The beam angle of the led light source of described substrate upper area is 30 degree.
Further, described led light source is evenly arranged on the substrate.
Further, the upper area on the described substrate is provided with 238 LEDs light sources, and lower area is provided with 84 LEDs light sources.
Further, described substrate is an aluminium base.
Further, described LED High-Pole Lamp also comprises lamp housing, is used for the supporting light sources system and the integral heat sink facility is provided, and described substrate is fixed in the lamp housing.
Further, described LED High-Pole Lamp also comprises Transparent lamp shade, as the light-emitting area of this High-Pole Lamp.
The advantage of the utility model is: through utilizing secondary lens; Beam Control is carried out in the led light source subregion; Make the LED High-Pole Lamp in illumination application, take into account remote projection and reach the closely characteristics of uniform irradiation; Promptly can realize shining deeply the remote projection of type High-Pole Lamp, can avoid the lamp stand near zone dark space to occur again than low-light (level).
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
