Description

A kind of modified LED light projector desk lamp
Technical field
The utility model relates to desk lamp technical field, specifically a kind of LED light-projecting type desk lamp.
Background technique
Traditional Table lamp structure is simple, and LED light negligible amounts, intensity of illumination is weaker, and illumination range is smaller, and cannot root According to needing real-time perfoming to adjust, be not able to satisfy each light it is weaker in the case where illumination needs.
Existing LED desk lamp, general structure include lamp holder, lamp bracket and lamp cap.Usual lamp cap can only be swung in above-below direction, Therefore the range of exposures of the light of the light bulb in lamp cap is very limited, must move when user will irradiate specific position whole A desk lamp is just able to achieve or even some angles cannot achieve irradiation, therefore is used very inconvenient.
In addition, current LED light-projecting type desk lamp, generallys use the symmetrical light distribution of wide-angle, desk lamp can only be placed in front Or left front, cause reflective serious, the irradiation light uniformity is poor, it is readily seen that light source, is easy to make eye fatigue.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of modified LED light projector desk lamp.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme:
A kind of modified LED light projector desk lamp, including pedestal, strut and lamp bar, strut lower end is mounted on the base, on strut It is set with bracket, lamp bar and bracket installation connect, and are equipped at least four groups of LED illuminating modules, LED illuminating module in the lamp bar Including LED light emitting source and spreadlight lens, spreadlight lens covers LED light emitting source, and lamp bar is equipped with gland, and gland is equipped with logical Hole, a part of spreadlight lens are caught in the exposed surface for facing LED light emitting source outside, on spreadlight lens in the through-hole of gland and set There is at least one inclined surface, so that four groups of LED illuminating modules form three or more different irradiation sides in the transverse direction of lamp bar To forming more than two different direction of illuminations in the longitudinal direction of lamp bar, the axial direction of lamp bar is longitudinal direction, lamp bar Radial direction is transverse direction.
In at least four groups of LED illuminating modules, whole spreadlight lenses it is parallel with the transverse direction of lamp bar and with longitudinal direction Direction has angle;Or the transverse direction and longitudinal direction of whole spreadlight lenses and lamp bar all have angle.
When more than two inclined surface are arranged on the spreadlight lens, which keeps the same direction Inclination.
In at least four groups of LED illuminating modules, when wherein having, there are two the same transverse direction sides that spreadlight lens is located at lamp bar Xiang Shi, the incorgruous setting in the inclined surface of two spreadlight lenses.
The both ends of the lamp bar are also installed with light cover.
The utility model is designed by using spreadlight lens, and by corresponding structure, so that each group LED illuminating module In the horizontal and vertical upper multiple direction of illuminations of formation of lamp bar, so that reflective less, range of exposures is wider, and the light uniformity is more preferably.
Detailed description of the invention
Attached drawing 1 is the utility model schematic perspective view;
Attached drawing 2 is the utility model decomposition diagram;
Attached drawing 3 is the schematic diagram of spreadlight lens in the utility model.
Specific embodiment
For the feature, technological means and specific purposes achieved, function that can further appreciate that the utility model, below The utility model is described in further detail in conjunction with attached drawing and specific embodiment.
As shown in figure 1 and 2, the utility model discloses a kind of modified LED light projector desk lamp, including pedestal 1, strut 2 With lamp bar 4,2 lower end of strut is mounted on pedestal 1, and bracket 3 is set on strut 2, and lamp bar 4 and the installation of bracket 3 connect, the lamp At least four groups of LED illuminating modules 6 are installed, LED illuminating module 6 includes LED light emitting source 61 and spreadlight lens 62, polarisation in item 4 Lens 62 cover LED light emitting source 61, and lamp bar 4 is equipped with gland 7, and gland is equipped with through-hole, and a part of spreadlight lens is caught in It is exposed in the through-hole of gland that the surface that LED light emitting source 61 is faced on spreadlight lens 62 is equipped at least one inclined surface 8 outside, So that four groups of LED illuminating modules form three or more different direction of illuminations in the transverse direction of lamp bar, in the longitudinal direction side of lamp bar To more than two different direction of illuminations are formed, the axial direction of lamp bar is longitudinal direction, and the radial direction of lamp bar is transverse direction side To.By the way that inclined surface is arranged on spreadlight lens, to LED light emitting source issue light formed folk prescription to irradiation, thus in lamp Item it is horizontal and vertical on be respectively formed multiple direction of illuminations, light distribution is more uniform, and range of exposures is wider.
In at least four groups of LED illuminating modules, whole spreadlight lenses it is parallel with the transverse direction of lamp bar and with longitudinal direction Direction has angle;Or the transverse direction and longitudinal direction of whole spreadlight lenses and lamp bar all have angle.
In addition, in all LED illuminating modules installed in lamp bar, the inclined surface on each spreadlight lens is all protected Hold same direction inclination or different directions inclination.
As shown in Fig. 3, when three inclined surface 8 being arranged on the spreadlight lens 62, which keeps same Direction inclination.Certainly, inclined surface perhaps two or five can be also set on spreadlight lens, and specific quantity has no Specific to limit, listed above is only explanation.
In at least four groups of LED illuminating modules, when wherein having, there are two the same transverse direction sides that spreadlight lens is located at lamp bar Xiang Shi, the incorgruous setting in the inclined surface of two spreadlight lenses.
The both ends of the lamp bar 4 are also installed with light cover 5, and light cover covers in lamp bar both ends, avoid the luminous mould of internal LED Group is by external interference.
In the utility model, by the way that inclined surface is arranged on spreadlight lens, so as to which directly LED illuminating module is mounted on It in lamp bar, does not need by mounting platform, using inclined surface, so that LED light emitting source is radiated at the center of the light on spreadlight lens Line deflecting forms the irradiation of multiple directions.The gland for yet facilitating installation spreadlight lens simultaneously does not need inclination installation, can make The appearance of entire lamps and lanterns is more beautiful, effectively increase light emitting angle.
It should be noted that it is practical new to be not limited to this above is only the preferred embodiment of the utility model Type, although the utility model is described in detail referring to embodiment, for those skilled in the art, still It can modify to technical solution documented by previous embodiment or equivalent replacement of some of the technical features, But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in Within the protection scope of the utility model.
