Abstract
The utility model discloses a parallel light beam LED lamp, belongs to a lighting device, and particularly relates to an LED lamp. The parallel light beam LED lamp comprises an LED light source (1), a lampshade piece (2), a convex lens (3) and a reflection cup (4). The parallel light beam LED lamp is characterized in that the LED light source (1) is located at the central position of the bottom of the reflection cup (4), the front end of the reflection cup (4) is provided with the lampshade piece (2), the central position of the lampshade piece (2) is provided with the convex lens (3), an internal light emitting point (12) of the LED light source (1) is located on the focus point of the convex lens (3), and through the size and position of the convex lens (3), all the directly irradiated divergent light beams (51) from the internal light emitting point (12) of the LED light source (1) penetrate through a body of the convex lens (3) and then are converged to be parallel light beams I(52); through the radian and length of the reflection cup (4), the scattered light beams passing through a curved surface (13) of the front end of the LED light source (1) are irradiated to the reflection cup (4) and then changed to be parallel light beams II (53) to be reflected out of the lampshade piece (2), the parallel light beams II (53) surround the parallel light beams I(52), and light beams emitted from different position points of the LED light source (1) form effective parallel light beams through full range of light distribution.
Description
Technical field
The utility model belongs to lighting device, particularly LED light fixture.
Background technology
The angle of typical LED illuminator outgoing beam and illuminator axis is generally between 0～80 degree, in order to obtain suitable illuminating effect, need to carry out secondary light-distribution design to LED illuminator, existing LED light fixture generally adopts reflector to carry out secondary light-distribution to LED illuminator.And paraxial rays is carried out to luminous intensity distribution, and the degree of depth of reflector will be very dark, cause the volume of light fixture larger, be unfavorable for product miniaturization the light-configuration mode of this dark reflector flashlight design that kicker light requires for there being small size.
Existing Chinese Patent Application No. is a kind of LED light fixture of 200910189869.4, comprises LED light source, lens and reflector, and described LED light source is positioned at the bottom of described reflector, and described lens are positioned at the front of described LED light source; Described LED light source has an axis, and the light that described LED light source sends comprises the light of close axis portion and the light away from axis portion, penetrates after lens luminous intensity distribution near the light of axis portion, penetrates after reflector luminous intensity distribution away from the light of axis portion.
Although foregoing invention technical scheme has been used utilizing lens luminous intensity distribution near axis portion light, but the ray structure of LED light source is not carried out to careful research, the position of having ignored the internal illumination point of LED light source and LED light source front end arc astigmatism face is different, the main of LED light source is to be sent by the internal illumination point of LED light source near axis portion light beam, should use position and the size of convex lens to open luminous intensity distribution for the location positioning of the internal illumination point of LED light source like this.
So should carry out from the position of the luminescence mechanism of LED light source and luminous point the structure of design lamps more meticulously according to foregoing invention scheme.
Utility model content
In order to overcome the deficiency of existing LED light fixture light beam astigmatism, the utility model provides a kind of collimated light beam LED light fixture, and not only light beam is parallel for this collimated light beam LED light fixture, and designs more scientific.
The utility model solves the technical scheme that its technical problem adopts: the utility model discloses a kind of collimated light beam LED light fixture, belong to lighting device, particularly LED light fixture, comprise LED light source, lampshade sheet, convex lens, reflector, it is characterized in that: described LED light source is positioned at the bottom center position of described reflector, reflector front end has lampshade sheet, there are piece convex lens in the middle position of described lampshade sheet, the luminous point of described LED light source inside is positioned in the focus of described convex lens, the size of described convex lens and position make all direct projection divergent beams from LED light source internal illumination point pool collimated light beam I through after described convex lens body, the radian of described reflector and length can make to become collimated light beam II after the scattered beam of LED light source front end arcwall face is irradiated to described reflector and reflect lampshade sheet, make its collimated light beam II around described collimated light beam I, the light that LED light source diverse location point sends forms more effective collimated light beam through gamut luminous intensity distribution.
The beneficial effects of the utility model are that collimated light beam LED light fixture mainly carries out careful research to the ray structure of LED light source, by the lane place of the internal illumination point of LED light source and LED light source front end arc astigmatism face although treat, include in different Position Design structures, such as having piece convex lens in the middle position of described lampshade sheet, the luminous point of described LED light source inside is positioned in the focus of described convex lens, and the size of described convex lens and position make all direct projection divergent beams from LED light source internal illumination point pool collimated light beam I through after described convex lens body; The radian of described reflector and length can make to become collimated light beam II after the scattered beam of LED light source front end arcwall face is irradiated to described reflector and reflect lampshade sheet, make its collimated light beam II around described collimated light beam I, can shorten the degree of depth of described reflector, greatly dwindle the volume of light fixture, be conducive to small size and the miniaturization of the flashlight of kicker light requirement is produced.
