The specific embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

With reference to Fig. 1, show the structural representation of a kind of Solar lamp of the utility model embodiment, comprise with the lower part:

Housing 101;

Be arranged on the solar panel 102 at housing 101 tops;

Be arranged on the controller 103 and the led light source 104 of mid portion in the housing 101;

Be arranged on the battery 105 of housing 101 bases 106;

Described solar panel 102 is used for to battery 105 charging, and described controller 103 is used to protect overcharging and/or overdischarge of battery 105, and, the startup of control led light source 104 and closing.

Solar panel is according to the photovoltaic effect principle, solar energy is converted to the energy converter of electric energy.In the present embodiment, for making solar panel can fully receive solar energy, described solar panel is arranged on case top, preferably, described solar panel is pressed in the glass by heat zone compression technology or other technological layer, thereby the intrusion of block water, mist, moisture, the service life of increase solar panel.For the outward appearance that makes Solar lamp is more apparent soft and graceful, the described solar panel that is arranged on housing is preferably circle, and certainly, it also is feasible adopting the solar panel of square, rhombus or other shape, and the utility model does not limit this.

The effect of controller is the duty of control solar energy system; the control charging and discharging of accumulator plays the effect of additives for overcharge protection, over to battery, thereby prolongs the service life of battery; preferably, control described in the utility model can also have light control functionality.For example, a kind of light-operated circuit of controller as shown in Figure 2, by day, because illumination is stronger, the internal resistance of photo resistance RG is very little, has this moment big electric current to make triode VT saturation conduction by RG, after VT is saturated, the 4. terminal voltage of controller DM is far below 1.6V, so end DM inside, illuminating lamp H can not light.Arrive when night, the light deepening, the luminous flux that is radiated on the RG weakens, and the internal resistance of RG becomes increasing, and controller DM internal circuit is also open-minded gradually, thereby has electric current to make it luminous by illuminating lamp H.Certainly, it also is feasible adopting other light-operated circuit to make controller have light control functionality, and the utility model does not limit this.

In practice, by adopting the solar panel of 2W, give the charge in batteries of 6V/4Ah, during to night, the light control functionality by controller can make the led light source of 1W start automatically and work about 4 hours; If run into (can't charge) overcast and rainy the time, described led light source still can be worked 3 days; And under the situation of illumination deficiency, battery tension lower (when promptly not reaching set under-voltage of controller), led light source still can normally start.Wherein, described LED (Lighting Emitting Diode) light source is a light emitting diode, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, by carrier compound energy of emitting surplus taking place causes photo emissions in semiconductor, directly send red, yellow, blue, green, blue or green, orange, purple, white light, LED be called as the 4th generation lighting source or green light source, have characteristics such as energy-saving and environmental protection, the life-span is long, volume is little.In the present embodiment by using this led light source, can make long, the characteristics such as power consumption is little, luminous quantity is bigger of the life-span that makes Solar lamp that the utlity model has.And described led light source can be for one or more, and for example, it all is feasible adopting the high-power LED light source of 1 1W or adopting the led light source of the integrated 1W of granule light emitting diode of 20 0.05W.Preferably, waterproof lampshade can also be set, thereby prevent that moisture from entering, guarantee the serviceability of led light source, prolong the service life of led light source in described led light source outside.

Certainly, those skilled in the art can be as required or experience other function of controller is set voluntarily, for example,, the temperature compensation function of controller etc. is set in the bigger place of the temperature difference, the utility model does not need this to limit.

Be well known that battery is generally lead-acid battery, in the little microsystem, also available Ni-MH battery, nickel-cadmium cell or lithium battery.Its effect be when illumination is arranged with the electrical power storage that solar panel sent, it's time to needs to discharge again.For battery can be out of shape because of the external force effect or come off, further reduce the possibility that various faults take place, present embodiment can also be in battery outer setting fixture 107.

With reference to figure 3, show the schematic diagram of a kind of housing base of the present utility model, preferably, the housing base is provided with and makes the on-deformable intersection bonding jumper 108 of housing, in this case, described fixture 107 is fixedly mounted on the described intersection bonding jumper 108, specifically, described fixture is a bonding jumper, fixing by using this bonding jumper that battery is intersected, the bonding jumper that intersects with the housing base passes through bolt or otherwise fixing then, thereby effectively fixes battery, and it can be out of shape because of the external force effect or come off.

With reference to figure 4, show the front view of a kind of Solar lamp of the present utility model, described housing is the cube with two cambered surfaces and two rectangular surfaces, in order to make described Solar lamp have better illumination effect, the mid portion of described housing is a diffuser 109, described diffuser 109 is arranged on two cambered surfaces, and described diffuser 109 is made up of a plurality of four diamond blocks.The printing opacity of a plurality of four diamond blocks designs, and can make the light milder of led light source, and is more soft and graceful, and has the effect of the covering that prevents dust.Preferably, the electric wire of described enclosure interior is all gone into controller along a side joint of housing, and is simple to operate, do not influence the aesthetic feeling of outward appearance.

More than a kind of Solar lamp provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
