Abstract

The utility model relates to an annular LED project lamp, comprising a lamp post and a quadrate LED lamp. The LED project lamp is characterized in that: the upper end of the lamp post is fixedly provided with an annular framework; and the outer circumference of the annular framework is uniformly distributed and articulated with a plurality of quadrate LED lamps. The annular LED project lamp is simple in structure and low in cost; the outside of the annular framework at the upper end of the lamp post is uniformly distributed and articulated with a plurality of quadrate LED lamps; the quadrate LED lamps can be adjusted in terms of angle along the vertical direction to cause an adjustment of the whole lighting area; as the shape of each light reflecting bowl results in more intensive light collection and higher brightness, the radiation range and the area of the lights are correspondingly increased; and the annular LED project lamp is suitable to be used as the square lamp and landscape lamp in different use environments.

Description

The annular LED Projecting Lamp

Technical field

The utility model belongs to the lighting apparatus field, especially a kind of annular LED Projecting Lamp.

Background technology

Lighting is requisite a kind of articles for use during people live, and not only makes people night can better be movable, has also decorateed environment, such as common road lighting, workshop illumination, the illumination of building garden landscape etc.The structure of these illuminating lamps is: comprise lamppost and light fixture, lamp installation is in the upper end of lamppost, light fixture comprises lamp housing, lampshade and bulb, lampshade is inlaid on the lamp housing, bulb is installed in the lamp housing behind the lampshade, and what above-mentioned bulb used is the bulb of common bulb or high brightness, but because the power of these bulbs is very big, its power consumption is also very big, has caused the waste of the energy.For saves energy, people just progressively use the low-power consumption LED lamp pearl of alternative common bulb, and these common square LED Lantern Festivals have economized electric power resource, but its illuminance is not enough, and what promptly can't shine is far, also can't illuminate bigger area.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, with low cost and projection distance is far away, illuminated area is big annular LED Projecting Lamp is provided.

The technical scheme that the utility model is taked is:

A kind of annular LED Projecting Lamp comprises lamppost and square LED lamp, and it is characterized in that: the upper end at lamppost installs annular frame, adorns a plurality of square LED lamps in the uniform hinge of the excircle of annular frame.

And, described annular frame comprises annulus, following annulus, crossbeam and vertical beam, last annulus and following annulus are by the coaxial outer rim that is packed in lamppost of crossbeam, and a plurality of vertical beams of the uniform installation in the outside of last annulus and following annulus all cut with scissors between two adjacent vertical beams and adorn square LED lamp.

And, described square LED lamp comprises lamp housing, lampshade, circuit board and LED lamp pearl, and lampshade is inlaid in an end of lamp housing, mounting circuit boards on the inwall of the lamp housing other end, uniform installation LED lamp pearl all is equipped with an independently reflector on the circuit board between each LED lamp pearl and the lampshade.

And the described lamp housing other end is embedded with and the contacted radiator of circuit board.

And described reflector is made upper shed and under shed, and upper shed is a light-emitting window, and under shed is sleeved on LED lamp pearl outer rim, and the cone angle of the circular cone that line constitutes between upper shed inner periphery and the under shed inner periphery is 40～65 ° or 65～90 °.

And the upper shed outer rim one of described reflector is made the sidewall coaxial with reflector, and assembling and positioning pin and assembling screw hole are made in the bottom of this sidewall.

And the outer surface radial equipartition of described sidewall is made a plurality of grooves.

Advantage of the present utility model and good effect are:

The utility model is simple in structure, with low cost, uniform hinge is adorned a plurality of square LED lamps in the annular frame outside of lamppost upper end, square LED lamp can vertically be adjusted angle, to adjust the area that integral body illuminates, and because that the shape of each reflector makes that light converges is more concentrated, brightness is higher, corresponding range and the area that has increased light is applicable to different environments for use such as Square Lamp, Landscape Lamp.

The specific embodiment

Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.

A kind of annular LED Projecting Lamp shown in Fig. 1～4, comprises lamppost 3 and square LED lamp 1, and innovation of the present utility model is: the upper end at lamppost installs annular frame, adorns a plurality of square LED lamps in the uniform hinge of the excircle of annular frame.Specifically, annular frame comprises annulus 2, following annulus 4, crossbeam 6 and vertical beam 5, last annulus and following annulus are by the coaxial outer rim that is packed in lamppost of crossbeam, the a plurality of vertical beams of the uniform installation in the outside of last annulus and following annulus, all cut with scissors between two adjacent vertical beams and adorn square LED lamp, the hinge dress is realized by hinge 7.

Square LED lamp comprises lamp housing 8, lampshade 11, circuit board 13 and LED lamp pearl 10, lampshade is inlaid in an end of lamp housing, mounting circuit boards on the inwall of the lamp housing other end, uniform installation LED lamp pearl all is equipped with an independently reflector 9 on the circuit board between each LED lamp pearl and the lampshade.Each LED lamp pearl on the circuit board is sleeved on one independently in the reflector, and this reflector upper end contacts with the lampshade inboard, and is separate between each reflector.

The various electric elements owing to gather on the circuit board, long-term use can be gathered a large amount of heats, so be embedded with and the contacted radiator 12 of circuit board bottom surface in the lamp housing other end relative with lampshade.

The structure of aforementioned each reflector is shown in Fig. 5～9: reflector inwall 17 is made for highly reflective material, its upper shed 19 is a light-emitting window, under shed 18 is sleeved on LED lamp pearl outer rim, the cone angle of the circular cone that line constitutes between upper shed inner periphery and the under shed inner periphery is 40～65 ° or 65～90 °, the light that last angle can make LED lamp pearl increases range satisfying under the prerequisite of illuminance, and the light that back one angle can make LED lamp pearl increases irradiated area satisfying under the prerequisite of illuminance.

For the ease of the installation of reflector, make the sidewall 15 coaxial in the upper shed outer rim one of reflector with reflector, assembling and positioning pin 14 and assembling screw hole 20 are made in the bottom of this sidewall.

Because sidewall adopts abundant material to make, and will certainly increase the weight and the production cost of reflector, so make a plurality of grooves 16 at the outer surface radial equipartition of sidewall.
