Description
Technical field
This practicality relates to a kind of lighting device, relates in particular to a kind of desk lamp lighting device.
Background technology
Present desk lamp, employed light source is general all to be bulb, electricity-saving lamp, count point source of light or strip light source that LEDs is combined into.Because factors such as restriction of the shape of point source of light or strip light source and light source luminescent are inhomogeneous cause the brightness irregularities of desk lamp irradiation, it is higher to occur local irradiation brightness like this, local irradiation brightness is on the low side, causes the actual illumination effect bad, and vision health is brought adverse effect; Inhomogeneous owing to what shine in addition, cause the loss of more luminous energy, therefore cause the loss of the energy.
For this reason, industry presses for and provides a kind of and can effectively utilize point source of light or strip light source, and makes the uniform desk lamp lighting device of illumination.
Practical content
Based on the deficiencies in the prior art, this practical problem to be solved provides the uniform desk lamp lighting device of a kind of illumination.
For addressing the above problem, this practicality provides a kind of desk lamp lighting device, it comprises lampshade, be arranged at light source in the lampshade, be arranged at optical diaphragm assembly and LGP in the lampshade, the light that described light source sends is processed into the light that is evenly distributed by optical diaphragm assembly again and penetrates behind the LGP mixed light.
Compared with prior art, the light that the light source of this practical a kind of desk lamp lighting device sends is after the LGP reflection, being processed into the light that is evenly distributed by optical diaphragm assembly again penetrates, the light overwhelming majority that light source is sent penetrates by optical diaphragm assembly, and the distribution of light that penetrates is even, thereby the brightness of irradiation is also even.Therefore to have a radiation response good in this practicality, the beneficial effect that the efficiency of light energy utilization is high.
As an embodiment of this practical a kind of desk lamp lighting device, described light source is a point source of light.
As an embodiment of this practical a kind of desk lamp lighting device, described light source is the strip light source.
As an embodiment of this practical a kind of desk lamp lighting device, described optical diaphragm assembly comprises: diffusion barrier sheet is used for utilizing diffusion to make distribution of light even from the light that LGP penetrates light source; The optically focused diaphragm, the light that the wide-angle that is used for that described diffusion barrier sheet is penetrated is disperseed compiles to irradiation area.Described optical diaphragm assembly also comprises reflection diaphragm, the top that it is arranged on light source, and the light that the departs from reflection that is used for light source is sent is to irradiation area.
As an embodiment of this practical a kind of desk lamp lighting device, described LGP has the micro-structural that can play the mixed light effect to light, and this micro-structural is the transparent configuration that one or more shapes in circular, square, triangle, the polygon constitute.
As an embodiment of this practical a kind of desk lamp lighting device, this device also comprises the power supply access device that inserts power supply and is connected in isolating transformer between power supply access device and the light source.
As an embodiment of this practical a kind of desk lamp lighting device, this device also comprises the lamp stand of base, hollow, and lead one end connects described isolating transformer, and the other end links to each other with power supply by the lamp stand of hollow.
For making this practicality easier to understand, further set forth this practical a kind of desk lamp lighting device below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is that this practical a kind of desk lamp lighting device structure in one embodiment splits schematic diagram.
Fig. 2 is the schematic diagram that light is propagated in the desk lamp lighting device among Fig. 1.
The specific embodiment
Description is described embodiment.
With reference to figure 1, a kind of desk lamp lighting device of present embodiment comprises power connection 1, lamp stand 2, base 3, lamp holder 4, and this lamp holder comprises lampshade 41, LGP 42, optical diaphragm assembly 43 and light source 44.
Described power connection 1 has isolating transformer 11, and this power connection 1 passes through to power to light source 44 after isolating transformer 11 transformations after connecing civil power, and this isolating transformer 11 not only plays transformer action, can also prevent that the user from getting an electric shock.
Described lamp stand 2 is installed on the base 3, and its inner hollow, two ends connect.Connect power connection 1 and pass the lamp stand 2 of this hollow, effectively protected lead so on the one hand, prevent that lead from damaging because of reasons such as wearing and tearing with light source 44 leads; Can make lead not expose the outside on the other hand, solving because of lead is exposed to the outside makes troubles to the user, influences problem attractive in appearance.
Described lamp holder comprises lampshade 41, LGP 42, optical diaphragm assembly 43, light source 44 and housing 45, and described light source 44 can be a point source of light, also can be the strip light source.Described point-like or strip light source are positioned at the top of LGP 42, and near LGP 42, the light that light source sends passes LGP 42, passes through the processing of optical diaphragm assembly 43 then.In lampshade 41 and housing 45 are wrapped in point-like or strip light source, LGP 42, optical diaphragm assembly 43, so that whole luminous component is protected; 45 pairs of optical diaphragm assemblies of housing 43 are protected fixing with LGP 42.
With reference to figure 2, LGP 42 has micro-structural, this micro-structural specifically can be circular, square, triangle, polygon etc. wherein one or more, the transparent configuration that its size and location all can change can draw by mold injection; The effect of micro-structural is propagation law and the propagation path that is used for changing light, reaches the mixed light effect.
Below specify the process of the interior light propagation of desk lamp: the light that light source 44 sends is by the effect of micro-structural on the LGP 42, with original point-like or strip light by scattering, effects such as diffuse reflection, light is evenly distributed in 42 whole of LGPs, to diffusion barrier sheet 433 emissions,, further carry out mixed light then by the diffuse reflection effect, make light luminance be more evenly distributed, light is softer; The light that penetrates from diffusion barrier sheet 433 is directive optically focused diaphragm 432 again, and the light that wide-angle is disperseed concentrates in the small range, with the brightness of the irradiation area that improves certain limit; The light that penetrates from optically focused diaphragm 432 this moment is second diffusion barrier sheet 434 of directive again, makes the last light luminance that penetrates distribute and further become evenly, and light is softer and enlarge irradiated area.In sum, the light of optical diaphragm assembly 43 after with LGP 42 mixed lights is further assembled and scattering, feasible irradiation has bigger brightness and better uniformity, and the desk lamp irradiation unit is become highly evenly and the area source of the reasonable brightness of tool, has significantly reduced light pollutions such as dazzle.Above-mentioned height evenly specifically is expressed as in the whole light-emitting area of LGP, and difference is very little between the brightness maximum of any point and the minimum of a value, such as: maximum is 10, and minimum is about 8.5.
Above disclosed only is this practical preferred embodiment, can not limit the interest field of this practicality certainly with this, and therefore the equivalent variations of being done according to this utility application claim still belongs to the scope that this practicality is contained.
