Detailed description of the invention
In order to make the object of invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.
As shown in Figures 1 to 4, a kind of LED lamp of even bright dipping, comprises and to irradiate and by the upper LED module of ceiling reflection light to ceiling, and the lower LED module irradiated downwards.LED lamp of the present invention is made up of the lower LED module of the upper LED module upwards irradiated and irradiation downwards, the light that upper LED module upwards irradiates can by ceiling reflection out, the light penetrated with lower LED module mixes, define good surround lighting, the excessively strong contours of the face shade of softening, decreases dazzle.The light of downward irradiation can give prominence to desktop, object and face etc., and make space seem more obvious, build vision excitement, this LED lamp is particularly suitable for office lighting, is conducive to the development and application of LED lamp.
Wherein, described upper LED module is 1:2 with the number ratio of lower LED module, and each upper LED module is between two lower LED modules.Light fixture adopts the mode of upper three times seven, namely to ceiling irradiate light about 30%, directly to the light of lower irradiation about 70%, this proportion composite considers utilization rate and the result of use of light source, adopts this ratio can reach preferably light-out effect, and has saved electric energy.
Wherein, the light diffusing sheet 2 that described lower LED module comprises strip-shaped bracket 1 and is installed in strip-shaped bracket 1, light diffusing sheet 2 is installed on the bottom of strip-shaped bracket 1, and the end face of strip-shaped bracket 1 is arc top surface, and the two sides of strip-shaped bracket 1 are rectangular surfaces; The cross section of described lower LED module is covering of the fan, and this covering of the fan is remove the center of circle fan-shaped, convenient splicing, and has mild radian, good looking appearance after splicing; Described upper LED module is inverted lower LED module; The joint face of described lower LED module and upper LED module is the side of strip-shaped bracket 1.The module of this LED lamp can splice according to the demand of user, and autgmentability is better, and ease of assembly becomes the light fixture of different capacity and specification.
Wherein, the forward and backward two ends of the strip-shaped bracket 1 of described LED lamp are respectively equipped with module fixed head 3, and lower LED module and upper LED module are fixed by module fixed head 3.The size of module fixed head 3 is decided by the number of required lower LED module and upper LED module, and the mode adopting two ends fixing, and structure is simple, stable connection.
Wherein, be provided with two pieces of aluminium bases be obliquely installed 4 in described strip-shaped bracket 1, every block aluminium base 4 is provided with the elongated surfaces intersecting angle of multiple LED light sources 5, two pieces of aluminium bases 4 in obtuse angle; Described light diffusing sheet 2 is located at outside LED light source 5.The two pieces of aluminium bases 4 being provided with multiple LED light source 5 are obliquely installed by this LED lamp, light source can be penetrated through light diffusing sheet 2 equably, and can not produce dark space, make LED lamp light out soft comfortable.
Wherein, the elongated surfaces intersecting angle of two pieces of aluminium bases 4 is 150 ° ~ 175 °.Best angle is 165 °.165 ° of best angles being through many experiments and drawing, adopt this angle to make the uniform in light emission of light fixture, can not produce dark space.
Wherein, be provided with two pieces of light source installing plates 11 be obliquely installed between the end face of described strip-shaped bracket 1 and light diffusing sheet 2, described aluminium base 4 is installed on light source installing plate 11.Light source installing plate 11 1 aspect plays the effect of the aluminium base 4 being fixed with LED light source 5, is conducive to the heat radiation of LED light source 5 on the other hand.
Wherein, described light diffusing sheet 2 is that PC that is transparent, arc covers, and the radian of PC cover is 70 ° ~ 80 °.The best radian of PC cover is 76 °.Light diffusing sheet 2 adopts the PC of arc to cover, and coordinates the angle of inclination of aluminium base 4, makes the light of light fixture directive all angles more even; Adopt radian to be that the PC cover of 76 ° matches with the aluminium base 4 at 165 ° of angles of inclination, meet arrangement height that LED light source 5 and PC cover evenly, go out the uniform state that light reaches the best, light is more soft comfortable.
Wherein, the special-shaped aluminium section that is formed in one of the end face of described strip-shaped bracket 1 and two sides, light source installing plate 11.This different in nature aluminium profile is simple, and can meet the uniform in light emission of LED module and the sliceable performance of LED module, function is more, is conducive to the development and application of LED lamp simultaneously.
Wherein, described LED lamp also comprises the erecting by overhang 6 for hanging, and the height of described erecting by overhang 6 is 0.7 meter ~ 1.3 meters.The height of erecting by overhang 6 is preferably designed to 1 meter, such reverberation and direct light syncretizing effect better, this is not highly absolute certainly, and user can adjust according to concrete conditions such as the height of ceiling, and flexibility is stronger.
Above content is only preferred embodiment of the present invention, and for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, this description should not be construed as limitation of the present invention.
