Abstract
The utility model provides a desk lamp with uniform and non-glare light, which is suitable for the illumination lamp field. The desk lamp comprises a lamp holder which is provided with a plurality of light-emitting modules which are evenly distributed at the periphery of a central shaft. The light-emitting module is capable of removing the projection of an object to emit uniform light. The light emitted from the luminous source enters from the side surface of a light guide plate, and reflects when passing the screen dots of the light guide plate, and reflects again when passing a reflective film on the top of the light guide plate, and then diffuses when passing a diffuser sheet below the light guide plate. The utility model is advantageous in that the emitted light is soft and uniform without glare.
Description
Technical field
The utility model belongs to field of illuminating lamps, relates in particular to a kind of even free from glare desk lamp.
Background technology
In the daily life, the common table lamp source adopts incandescent lamp or fluorescent tube more, the design of reflection shield or reflecting piece is substantially all adopted in the lamp holder design, such fitting structure makes that common desk lamp brightness may be too concentrated in a certain direction, the light on the desktop can be inhomogeneous when reading, work for people, and because the lamp holder of common desk lamp is open, eyes may be seen luminous light source often, if under the not good situation of surround lighting, human eye is easy to and can produces discomfort because of strong excessively light, forms dazzle.
The utility model content
The purpose of the utility model embodiment is to provide a kind of even free from glare desk lamp, is intended to solve the problem that there is non-uniform light in common desk lamp and dazzle occurs.
The utility model embodiment realizes like this, a kind of even free from glare desk lamp, described desk lamp comprises lamp holder, described lamp holder is provided with a plurality of light emitting modules, described a plurality of light emitting module be evenly distributed on a central shaft around, described each light emitting module comprises pcb board, light emitting source, LGP, reflectance coating and diffusion sheet, described light emitting source is welded on the described pcb board, described pcb board is positioned at by the side of described LGP, the upper surface of described LGP is provided with the site, described reflectance coating is positioned at the top of described LGP, and described diffusion sheet is positioned at the below of described LGP.
In the said structure, described lamp holder is provided with 5 light emitting modules, described 5 light emitting modules be evenly distributed on a central shaft around.
In the said structure, described pcb board is welded with the one side of light emitting source towards described LGP side.
In the said structure, the one side that described pcb board is not welded with light emitting source is provided with fin.
In the said structure, described light emitting source is LED lamp or fluorescent lamp.
In the said structure, described pcb board be positioned at a side of described LGP other or be positioned at the dual-side of described LGP other be positioned at three sides of described LGP other or be positioned at described LGP around.
In the said structure, described site is latticed.
In the said structure, described site is a point-like.
In the said structure, described LGP is a makrolon material.
In the said structure, described LGP is an acrylic material.
In the utility model embodiment, lamp holder is provided with and is evenly distributed on a central shaft a plurality of light emitting modules all around, light emitting module can be eliminated the projection of object, make light emitting module luminous evenly, and the light that light emitting source sends is injected the site reflection on the light process LGP from the side of LGP, and through the reflection of the reflectance coating above the LGP, the diffusion sheet diffusion of the below of process LGP again makes emergent ray soft evenly, reaches the purpose of not dazzle.
