Description

The LED lighting device that a kind of angle is adjustable
Technical field
The utility model relates to the adjustable LED lighting device of a kind of angle, belongs to technical field of lighting fixtures.
Background technology
Colourity is good, non-maintaining, the life-span long, save the features such as the energy because it has for LED light source, and in China, lighting field is used widely.Tradition LED lighting device, its light direction only has two kinds, and one is that fixed-direction irradiates, for example LED street lamp; Another kind of common LED bulb or lamp rod, do not have fixing direction of illumination.No matter be above-mentioned which kind of LED light source, all cannot realize the adjustment of lighting angle and scope, and in the each field of daily productive life, often appearance need to be adjusted the situation of light-source angle and scope, these are all that prior art cannot realize.
Summary of the invention
Technical problem to be solved in the utility model is to provide the adjustable LED lighting device of a kind of angle, has the features such as rising angle is adjustable, the saving energy, with low cost, application is extensive.
The utility model is achieved by the following technical solution:
The LED lighting device that a kind of angle is adjustable, comprise LED light source, constant-current source, substrate, fin, substrate comprises a bottom surface and side, two of left and right, substrate bottom surface is fixedly connected with LED light source with the inner side of two sides, fin is fixed on substrate bottom surface and outside, two sides, LED light source connects constant-current source, special feature is: substrate bottom surface lower limb is provided with two articulated joints, substrate side surfaces lower limb is respectively provided with an articulated joint, and substrate bottom surface articulated joint is hinged by expansion link with side articulated joint respectively.
The LED lighting device that a kind of angle as above is adjustable, LED light source is made up of LED compound lens, LED lamp pearl and aluminium base, and LED lamp pearl is series on aluminium base, and LED compound lens is located at LED lamp pearl top, and the aluminium base back side scribbles heat-conducting silicone grease.
The LED lighting device that a kind of angle as above is adjustable, substrate bottom surface and substrate side surfaces inner side are at least respectively fixed with one group of LED light source.
The LED lighting device that a kind of angle as above is adjustable, wherein substrate material is the metallic plate that inner side can reflection ray.
The LED lighting device that a kind of angle as above is adjustable, wherein substrate bottom surface and substrate side surfaces side are connected through the hinge.
Adopt the LED lighting device of this kind of structure, can be according to different lighting demands, adjust expansion link and reach the change of substrate bottom surface and substrate side surfaces angle by cooperation, realize the variation of light angle and scope with this, simultaneously, due to adding of side light source in substrate bottom surface, greatly strengthen the exposure intensity perpendicular to substrate bottom surface direction, inside substrate, good reflective function can reflex to road surface to greatest extent by the light of LED light source transmitting, the advantage such as have the energy of saving, with low cost, illumination zone is adjustable, application is extensive.
