Abstract
The invention provides an LED (Light-Emitting Diode) illuminating device with a rotary light source. An LED luminous body is rotationally arranged on a fixed base, and comprises a shell and a circuit board which is positioned in the shell and is fixed to control dynamic light change; the circuit board is connected with a power supply through an electric wire; the lower part of the shell is connected with a conical rotary bump; a plurality of smooth hemispheres I are uniformly distributed on the conical rotary bump; rotary recesses are fixed to the fixed base, and are matched with the conical rotary bumps; a plurality of smooth hemispheres II are uniformly distributed on the concave surfaces of the rotary recesses; the smooth hemispheres II and the smooth hemispheres I are arranged in a staggered way, so that the LED luminous body can rotate optionally relative to the rotary recesses. By adopting the LED illuminating device, the illumination strength can be concentrated effectively in a larger angle range, and the illumination range can be flattened.
Description
Technical field
The present invention relates to a kind of LED lighting device, especially about a kind of LED lighting device with rotation light source.
Background technology
LED has that volume is little, lightweight, power consumption less, the advantage such as the life-span is long, the response time is short and anti-seismic performance is good.Therefore, the application of LED has been not limited only to signal designation light source, progressively from outdoor applications such as indoor trend such as traffic lights, car light, outdoor-screens.One of essential annex when camera flash lamp is camera shooting, especially for on-the-spot light, compared with news rambunctious, take or the shooting of on-the-spot insufficient light for, need flash lamp to carry out light filling to reference object, thereby flash lamp is the key factor that guarantees to take image quality.Existing flash lamp for shooting is that luminous body is arranged on a fixed pedestal, by this fixed pedestal, obtains electric weight, in flash lamp top, is provided with a reflector, reaches the object of optically focused by this reflector.
Flash lamp has certain lighting angle, and this lighting angle should match with camera lens visual angle, is at least equal to or greater than camera lens visual angle, otherwise photo edge part branch is because not having polishing dimmed, thereby reduce, takes quality; Take at present flash lamp used and mostly adopt LED, yet, the light angle of departure of LED is larger, only by a reflector, be difficult to reach the object of centralized lighting intensity, thereby can cause illumination range larger, if reach desirable luminous intensity, need to increase luminous power, but can cause like this power consumption larger.
The illuminating lamp that at present automobile uses, when night running, its brightness of illumination only have distance and power minute, if when two cars meet, both sides driver is with dazzling feeling, and the side of light a little less than is relatively even more serious; And because the sight line of automobile is unclear, the traffic accident that often can cause generation should not occur; In the adverse circumstances such as mountain area and detour, travel, due to light direct projection, thereby driver's driving difficulty is increased; When the harsh weather such as greasy weather, also can be difficult to drive.Provide a kind of can be in polarizers of big angle scope more all illumination intensity and LED lighting device that can flattening illumination range in active set.
Summary of the invention
The object of the present invention is to provide a kind of can active set in illumination intensity and LED lighting device that can flattening illumination range.
In order to realize object of the present invention, the invention provides a kind of LED lighting device with rotation light source, comprise fixed pedestal, built-in portion and LED illuminator, described LED illuminator is placed on described fixed pedestal, described built-in portion covers in the top of described fixed pedestal and accommodates described LED illuminator, this LED lighting device also comprises a set of lenses, and described set of lenses is comprised of spherical lens and cylindrical lens, and described cylindrical lens is positioned at the top of spherical lens, described set of lenses be set on the madial wall of described built-in portion and be positioned at described LED illuminator directly over, and the vertical curvature of described set of lenses is greater than its horizontal curvature, described built-in portion is the cylinder of a upper and lower opening, the curved surface of described cylindrical lens is positioned at vertical direction, described LED illuminator is placed on described fixed pedestal rotationally, described LED illuminator comprises shell, and be positioned at described shell and be fixed on the circuit board of controlling dynamic light change, described circuit board is connected with power supply by electric wire, in the bottom of shell, be connected with the prominent body of conical rotation, on the prominent body of described conical rotation, there is the some round and smooth shape hemisphere one of evenly arranging, on described fixed pedestal, be fixed with rotation concave volume, described rotation concave volume mates with the prominent body of described conical rotation, on the concave surface of described rotation concave volume, be placed with some round and smooth shape hemispheres two, round and smooth shape hemisphere two is staggered with round and smooth shape hemisphere one, described LED illuminator can be rotated arbitrarily with respect to described rotation concave volume.
Preferred described fixed pedestal is made by epoxy resin.
LED lighting device of the present invention can be in compared with polarizers of big angle scope illumination intensity and can flattening illumination range in active set.
Accompanying drawing explanation
Fig. 1 is the cutaway view of LED lighting device embodiment of the present invention;
LED lighting device of the present invention is applicable to take the flash lamp using, the light-emitting devices such as car lighting lamp.
Please refer to Fig. 1, the LED lighting device of band rotation light source of the present invention, comprise fixed pedestal 100, built-in portion 200 and LED illuminator 1000, described LED illuminator 1000 is placed on described fixed pedestal 100, described built-in portion 200 covers in the top of described fixed pedestal 100 and accommodates described LED illuminator 1000, this LED lighting device also comprises a set of lenses, and described set of lenses is comprised of spherical lens 400 and cylindrical lens 420, and described cylindrical lens 420 is positioned at the top of spherical lens 400, described set of lenses be set on the madial wall of described built-in portion 200 and be positioned at described LED illuminator 1000 directly over, and the vertical curvature of described set of lenses is greater than its horizontal curvature, described built-in portion 200 is the cylinder of a upper and lower opening, the curved surface of described cylindrical lens 420 is positioned at vertical direction, described LED illuminator 1000 is placed on described fixed pedestal 100 rotationally, described LED illuminator 1000 comprises shell 800, and be positioned at described shell 800 and be fixed on the circuit board 900 of controlling dynamic light change, described circuit board 900 is connected with power supply by electric wire 500, in the bottom of shell 800, be connected with the prominent body 801 of conical rotation, on the prominent body 801 of described conical rotation, there is the some round and smooth shape hemisphere 1 of evenly arranging, on described fixed pedestal 100, be fixed with rotation concave volume 600, described rotation concave volume 600 mates with the prominent body 801 of described conical rotation, on the concave surface of described rotation concave volume 600, be placed with some round and smooth shape hemispheres 2 803, round and smooth shape hemisphere 2 803 is staggered with round and smooth shape hemisphere 1, described LED illuminator 1000 can be rotated arbitrarily with respect to described rotation concave volume 600, described fixed pedestal (100) is made by epoxy resin.
