Description

View desk lamp

Technical field

The utility model relates to a kind of putting provides micro-landscape, sand table model to appreciate and the device of LED illumination functions on the table, refers in particular to the micro-landscape lamp decoration with glass protecting cover.

Background technology

At present, market can be seen some ornaments inner microlandscape with low-power LED lamp decorations function or sand table model product on the table, the miniatures such as house furniture, machine installation, personage animal, flowers, plants and trees, chain of mountains river are arranged in the inside, major function appreciates as displaying, inside does not possess substantial light photograph, can not use as light fixture.Separately there are some desk lamps, miniatures is put as lamp decoration below lamp body light source, the deficiency that they exist is, effect is overlooked in the light source part impact covering larger area above view, and the model of view area the inside less than normal is single, scenery can appreciating and overall visual effect poor, though there is illumination functions can not embody the perfect view of similar sand table model.

Summary of the invention

Interior lighting function is lacked for solving the small-sized sand table landscape model of existing desktop, and effect is overlooked in the light source part impact that the desk lamp with microlandscape exists larger area, and the single problem that can not show the perfect landscape effect that sand table model has of the general scenery less than normal of view area, the utility model can provide again enough brightness illumination functions can not stop the view desk lamp overlooking sight line by providing a kind of sand table model possessing more complete micro-landscape simultaneously.

The technical solution adopted in the utility model is: one by cylindrical base, the micro scenery of submounts, transparent glass cover, the view desk lamp that the LED light source at top and power supply unit are formed, wherein, transparent glass cover is hemispherical shape, multiple pit is had in cloche top underside, having its Metal Substrate seat surface of two groups of LED chip of warm white and the encapsulation of cold white light miniature patch to be mounted in each pit makes plane of illumination down, the positive and negative electrode often organizing LED chip connects to form LED array by the thin copper conductor be laid on glass surface, two groups of LED array are connected to the light drive output of a controller of cylindrical base inside equally with thin copper conductor, one piece of liquid crystal digital display cylindrical base side is equipped with, and be electrically connected to the display driver port of one piece of clock circuit of chassis interior, the timing output of clock circuit is connected with the time signal input of controller, the one group of control button panel be arranged on cylindrical base side is electrically connected the control input end of clock circuit and controller, the sound driver output of a loudspeaker connection control device on cylindrical base, power supply unit connects clock circuit and controller provides voltage.LED light source provides required light for landscape model and surrounding environment, and colour temperature and the brightness of LED is regulated by control button panel, liquid crystal digital display provides time calendar display and control to arrange display under clock circuit drives, being arranged by the adjustment of control button panel makes clock circuit allow controller carry out timing controlled to LED light source or loudspeaker when needed, driving LED light source works or loudspeaker send alarm clock and animal and the sound such as to pipe, and simulate the natural landscape under some microlandschafts.

Owing to adopting hemisphere bodily form transparent glass cover as scenery dustproof protecting cover, LED chip and wire are hidden in cloche top, almost can't see light source part, so both can not affect and overlook scenery, four-way sight line is open, appearance and modeling is graceful, and keeping light, irradiate downwards from top can not be dazzling, the well-balanced nature of light shadow surface brightness, enough brightness of illuminations can be provided for surrounding environment, desk lamp is provided with the sand table model micro-landscape appreciation effect of larger area simultaneously, the brightness of light adjustable color temperature, start by set date can also be provided or close light source, quarter-bell and other audio function.

Detailed description of the invention

As shown in Figure 1, on a cylindrical base 1 large by the diameter 50 centimetres of plastic shaping, the micro scenery 2 be made up of some houses, trees, river, meadow etc., the cloche 3 that hemisphere bodily form is transparent cover micro scenery 2 is installed with cylindrical base 1 fixing, cloche 3 top is installed with LED light source 4, cylindrical base 1 side is filled with one piece of liquid crystal digital display 6 and one group of control button panel 7.LED light source is arranged on the cross-sectional configuration at cloche top as shown in Figure 2, cloche 3 inner face has the diameter about pit 31 of several millimeters, the paster LED of each pit 31 correspondence dress subsides micro volume 0.5W power, here for warm white LED chip 41, by paste adhesive excellent for the metal base heat conductivility of its chip bottom in pit 31 bottom surface, each LED chip 41 electrode is connected in series by the good thin copper conductor 5 of electric conductivity, and thin copper conductor 5 is laid on cloche 3 inner face with gluing the connecing of conductive, transparent, the resistance that can reduce wire like this improves electric conductivity, the heat produced during LED work simultaneously then carries out heat conduction by large-area cloche 3 and disperses.The warm white that whole LED light source connects to form and cold white light two groups of configurations of light sources are as shown in Figure 3, here always have 12 LED chip 41,42 and surround circular distribution at cloche top, wherein the array of six warm white LED chip 41 compositions and the array of six cold White-light LED chip 42 compositions are by being laid on thin copper conductor 5 packet concatenation on glass surface, form two groups of each light sources of three watts, thus the brightness of illumination reached needed for desk lamp, two groups of LED chip 41,42 arrays are connected to controller with the thin copper conductor 5 be laid on glass surface equally.Fig. 4 describes the circuit principle of compositionality of the present embodiment view desk lamp, the light drive output of controller 9 connects warm white and cold white light two groups of LED chip 41, 42 arrays, the sound driver output of a loudspeaker 11 connection control device 9, the display driver output of clock circuit 8 connects liquid crystal digital display 6, there is a timing signal to export the time signal input connecing controller 9 simultaneously, the control input end of control button panel 7 connection control device 9 and clock circuit 8, realize the adjustment to time and LED light source 4, power supply unit 10 voltage circuit connection control device 9 and clock circuit 8, power to each circuit.Wherein clock circuit 8, controller 9, power supply unit 10 and loudspeaker 11 are arranged on cylindrical base inside.
