Abstract
The utility model relates to a solar charged desk lamp or a portable lamp. A circuit of the utility model is composed of a charging circuit and a light emitting circuit, wherein the charging circuit is composed of an external connection solar charger, a charging socket PJ1, a protective diode D0 and a rechargeable battery BT1, and a plurality of LED white light spherical lamps and a current limiting resistor are connected in series and then are connected in parallel to form the light emitting circuit. The charging socket PJ1 is externally connected with the solar charger. The resistor has a function of current limiting protection. The utility model utilizes solar light to charge the rechargeable battery of the desk lamp or the portable lamp in a photoelectric conversion mode and provide energy for the luminescence of the LED white light spherical lamps. Therefore, during day, the desk lamp or the portable lamp is charged, and at night, the desk lamp or the portable lamp can provide light. The utility model provides an ideal illuminating lamp for users who are in areas with power shortage, or work in the field, or are not near an electric network. The utility model adopts the rechargeable battery (including a storage battery) as a power supply, no electromagnetic interference happens, no pollution of radiation of electromagnetic waves appears, the LED white light spherical lamps emit light in a constant mode, the stroboflash can be thoroughly eliminated, and the vision is protected.
Description
Technical field
The utility model relates to a kind of solar recharging desk lamp or hand lamp, particularly a kind of solar recharging desk lamp or hand lamp that uses with the solar charger charging.
Background technology
At present, known charge desk lamp or hand lamp all are to use with the charging of electric energy charger, are unwell to power-shortage area, field work or keep clear of the place of electrical network.
Summary of the invention
The purpose of this utility model provides a kind of solar recharging desk lamp or hand lamp that uses with the solar charger charging.
The technical solution of the utility model is: solar recharging desk lamp or hand lamp circuit are by external solar charger and charging socket PJ1, protection diode D
0, the illuminating circuit that then composes in parallel of rechargeable battery BT1 charging circuit, several LED white light globe lamps and the current-limiting resistance series connection formed forms.Solar recharging desk lamp parts comprise lamp socket (including battery case or battery compartment), lampshade, lamp plate, reflex reflector lens etc.
The utility model is owing to be to utilize sunlight to give the rechargeable battery charging of desk lamp or hand lamp by opto-electronic conversion, the luminous energy that provides of LED white light globe lamp is provided, the night illumination of charging daytime like this, the user who can be power-shortage area, field work or keep clear of electrical network provides desirable lighting.The utility model adopts rechargeable battery (containing storage battery) as power supply, does not therefore have electromagnetic interference, does not have electromagenetic wave radiation to pollute, and can protect user's brain, and LED white light globe lamp is constant luminous, can thoroughly remove stroboscopic, vision protection.
Description of drawings
Fig. 1 is the circuit theory diagrams of a kind of embodiment of the utility model.
Specific embodiments
According to shown in Figure 1, solar recharging desk lamp or hand lamp circuit are by external solar charger (1) and charging socket PJ1 (2), protection diode D
0(3); the charging circuit that rechargeable battery BT1 (4) forms; the illuminating circuit that several LED white light globe lamps (5) and current-limiting resistance R (6) series connection then compose in parallel is formed; the external solar charger of charging socket PJ1 (2) (1); the power supply that solar charger (1) provides is by charging socket PJ1 (2); charge to chargeable rechargeable battery BT1 (4) through protection diode D0 (3); protection diode D0 (3) adopts Schottky diode; pressure drop is less; can guarantee higher charging voltage; can play the effect of rechargeable battery BT1 (4) that prevent in addition to external solar charger (1) discharge; each resistance R (6) resistance unanimity; LED white light globe lamp (5) is played the current-limiting protection effect, and protection LED white light globe lamp (5) also makes the luminous unanimity of several LED white light globe lamps (5).Open desk lamp switch (7) during use, rechargeable battery BT1 (4) makes LED white light globe lamp (5) shinny to the illuminating circuit discharge, and electric current flows to battery cathode through current-limiting resistance R (6).
Claims (1)
1, a kind of with solar recharging desk lamp or hand lamp, it is characterized in that by external solar charger (1) and charging socket PJ1 (2), protection diode D
0(3), the illuminating circuit composition that then composes in parallel of rechargeable battery BT1 (4) charging circuit, several LED white light globe lamps (5) and current-limiting resistance R (6) series connection formed, the external solar charger of charging socket PJ1 (2) (1).
