Description
Technical field
The invention belongs to the LED lighting technical field, particularly relate to a kind of LED Down lamp.
Background technology
Down lamp is a kind of lighting that is embedded into light down-ejection type in the ceiling.Its maximum characteristics are exactly to keep the integral body of building decoration unified and perfect, can not destroy the perfect unity of furred ceiling art because of the setting of light fixture.This latent the putting property light fixture that is flush-mounted in ceiling inside, all light be projection downwards all, belongs to direct luminous intensity distribution.Can obtain different light effects with different reflectors, eyeglass, shutter, bulb.Down lamp does not take up space, and can increase the soft atmosphere in space, if want to build warm sensation, can try to install many Down lamps, alleviates space constriction.Generally in the hotel, family, coffee shop use more.
LED Down lamp of the prior art, its light source arrangement mode is mostly continued to use conventional incandescent Down lamp form, and promptly the employing center is the form that the light direct beam light hole of reflecting surface, LED lamp around led light source, light source are set.But, such light source arrangement mode only is fit to big, the uniform conventional light source of light intensity distributions of exiting surface, and be not suitable for led light source, led light source has that exiting surface is little, light intensity distributions is concentrated, directive property is strong, need characteristics such as good heat radiating, and adopt above-mentioned conventional light source arrangement, can cause the illumination light intensity distributions non-uniform illumination scope of LED Down lamp little, brightness concentrations decorative effect is poor, light source is assembled problems such as radiating effect difference.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of LED Down lamp, change the light source arrangement mode, make that its illumination light intensity distributions is even, illumination zone is big, brightness is not concentrated, visual effect is soft, thereby has good decorative lighting effect, and, can effectively improve its heat dissipating state.
To achieve the above object, the present invention has adopted following technical scheme:
A kind of LED Down lamp, comprise mask plate, in the middle of the described mask plate is light hole, be fixed with reverberation bowl and a plurality of LED lamp on the mask plate, the bowl inwall of described reverberation bowl is a reflecting surface, the rim of a bowl bore of reverberation bowl is greater than the light hole aperture of mask plate, and described LED lamp is fixed on the mask plate in the face of reverberation bowl the rim of a bowl, and the light direction of described LED lamp is in the face of the reflecting surface of reverberation bowl.
This programme is broken through tradition and is concentrated the light source arrangement mode, led light source is arranged in employing around reverberation bowl the rim of a bowl, the light direction of led light source is in the face of the reflecting surface of reverberation bowl, like this, make the light of LED lamp outgoing in reverberation bowl, penetrate from light hole through reflection back repeatedly, though optical energy utilization efficiency slightly reduce,, the light that led light source directive property is strong, luminous intensity is concentrated makes that through repeatedly reflecting to form diffuse scattering the brightness of illumination of light hole is even more, the illumination and decoration better effects if; And, adopt led light source arranged around structure, avoided led light source centralized arrangement in the traditional design to cause the shortcoming that fully to dispel the heat in the confined space, make radiator structure that bigger design space and better heat radiating effect be arranged, for example, mask plate adopts heat-conducting metal material (aluminium matter), and the LED aluminium base directly contacts by mask plate with mask plate heat conduction and dispels the heat.
Above-mentioned mask plate is a mask plate annular one or that be spliced into annular, the described mask plate side of being annular, annular or oval ring, the rim of a bowl shape and the mask plate shape of described reverberation bowl are complementary, described a plurality of LED lamp is distributed on the LED substrate that is complementary with the mask plate shape, this LED substrate be annular one or be spliced into annular.
Above-mentioned LED substrate comprises line layer and aluminium base flaggy.
As preferably, the corresponding light hole of above-mentioned mask plate position is provided with light-passing board, and preferred again, light-passing board is a pulverizer plate.Adopt light-passing board can avoid outside contamination and infringement, especially pulverizer plate can further improve the illumination and decoration effect.
As preferably, above-mentioned mask plate is provided with the aluminium matter mask plate of heat transmission groove or projection for the surface.Can increase area of dissipation like this and further improve radiating effect.
As preferably, the reflecting surface of above-mentioned reverberation bowl is the minute surface or the atomizing face of coating white paint.The coating white paint can reduce the luminous energy absorption and improve the efficiency of light energy utilization, according to using needs, makes brightness of illumination improve thereby adopt minute surface can improve light reflectivity, further improves the illumination and decoration effect thereby employing atomizing face can increase the light diffuse scattering.
The fixed form of mask plate and reverberation bowl has multiple, one of preferred be: be fixed with the lamp tube on the described mask plate, be fixed reverberation bowl by gland in the lamp tube, convenient like this installation made, and clamp button of the spring can be set to fix with the ceiling furred ceiling in lamp tube both sides; Preferred two are: described reverberation bowl is fixed on the mask plate by screw, and is simple in structure like this, save cost.
As preferably, the reflecting surface of above-mentioned reverberation bowl is hemisphere face, parabola or ellipsoid; Certainly, reflecting surface can also be made a plurality of planes and the formation of curved surface mixed transition according to concrete structure and luminous intensity distribution needs.
As preferably, above-mentioned LED lamp light direction is to the centroclinal setting of the reflecting surface of reverberation bowl.Help improving the reflection condition of light in reverberation bowl like this and improve the efficiency of light energy utilization, preferably adopt the center line of LED lamp light direction to become 5 °～20 ° angles of intersection with the center line of reflecting surface.
The present invention is owing to adopted above technical scheme, led light source is arranged in employing around reverberation bowl the rim of a bowl, the light direction of led light source is in the face of the reflecting surface of reverberation bowl, make that illumination light intensity distributions of the present invention is even, illumination zone big, brightness is not concentrated, visual effect is soft, thereby has good decorative lighting effect, and, can effectively improve its heat dissipating state.
