Abstract

The utility model discloses a lighting device, in particular to a portable LED (light-emitting diode) rechargeable lamp. The portable LED rechargeable lamp comprises LED lamps arranged on a shell, an LED component controlling the LED lamps, and a solar cell panel, wherein the solar cell panel is connected with the LED component controlling the LED lamps through a power supply lead. With the adoption of the structure, the solar cell panel can charge a lithium cell directly through a voltage reduction and stabilizing circuit; the lithium cell of the LED component can store electricity to achieve lighting for a long time; in addition, the designed structure of the portable LED rechargeable lamp is simple; compared with the traditional light sources, the adopted LED rechargeable lamp has the advantages of few parts, small size, light weight, long service life, low energy consumption, no pollution and the like, thereby meeting requirements of environmental protection, safety and easiness in carrying; an adopted change-over switch capable of switching output power of an output control circuit can switch rapidly according to actual demands; and the one-time lighting time of the LED lamp is prolonged. Therefore, the portable LED rechargeable lamp meets use requirements of people.

Description

The Portable LED rechargeable lamp

Technical field

The utility model relates to a kind of lighting device, and specifically a kind of Portable LED rechargeable lamp belongs to field of illumination lamp technology.

Background technology

Illumination under the condition out of doors has demand widely.Also do not have electrical network to cover for some remote mountain areas and more external island especially, the local resident can only use kerosene or timber to light a fire as light source, lacks the effective lighting instrument, causes life inconvenience.The area that does not have covering traditionally for outdoor conditioned disjunction electric power networks; Usually use the power supply of common rechargeable battery as ligthing paraphernalia; Along with science and technology development,, also be used for the daily life illumination and use though solar energy has obtained using comparatively widely as a kind of novel energy; Can address this problem to a certain extent; But the technology that the electric energy that utilizes conversion of solar energy that exists in the prior art throws light on is still not mature enough, has satisfied not the needs of people's daily lifes, therefore still need improve.

Summary of the invention

The technical problem that the utility model will solve provides a kind ofly can utilize solar recharging and the environmental protection that can throw light on for a long time, Portable LED rechargeable lamp safe, easy to carry.

In order to solve the problems of the technologies described above; The Portable LED rechargeable lamp of the utility model; Comprise being installed in LED lamp and a LED assembly of control LED lamp on the housing that also comprise solar panel, said solar panel is connected with the LED assembly of controlling the LED lamp through power supply lead wire.

Decompression voltage regulator, overload protecting circuit, lithium battery that said LED assembly comprises; Said solar panel successively through behind the decompression voltage regulator, overload protecting circuit to lithium cell charging, said lithium battery is through output control circuit control LED lamp.

Said housing is provided with the change-over switch that can switch the size of output control circuit power output.

Said solar panel is the non-crystal silicon solar cell plate.

After adopting above-mentioned structure; Solar panel can be realized lithium battery is directly charged through decompression voltage regulator, and the lithium battery of LED assembly can be stored electric weight to obtain long illumination, and its project organization is simple simultaneously; The LED lamp that adopts has with respect to conventional light source that parts are few, volume is little, in light weight, the life-span is long, energy consumption is little, advantage such as pollution-free; Satisfied Environmental Safety, portable requirement, can the changing fast according to the actual requirements of setting to the change-over switch that the size of output control circuit power output is switched; Prolong lighting hours of LED lamp, therefore satisfied people's instructions for use.

Fig. 2 is the control circuit sketch map of the utility model Portable LED assembly.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment, the utility model Portable LED rechargeable lamp is done further explain.

As shown in the figure; The Portable LED rechargeable lamp of the utility model, comprise the LED assembly of LED lamp and control LED lamp, LED lamp be set to one group above and be installed in the housing 2; Also comprise the non-crystal silicon solar cell plate; Non-crystal silicon solar cell plate 1 outside is the aluminium frame, and the aluminium frame can and be made according to actual operating position design, can support the various fixed mode; Said non-crystal silicon solar cell plate is connected through the LED assembly of power supply lead wire 3 with control LED lamp, and described power supply lead wire can be connecting line or cable; Be provided with decompression voltage regulator, overload protecting circuit, lithium battery in the LED assembly; The function of said overload protecting circuit can comprise over-charge protective, cross the protection of putting protection and three kinds of forms of short-circuit protection; The non-crystal silicon solar cell plate successively through behind the decompression voltage regulator, overload protecting circuit to lithium cell charging; Concrete charging process is: through lowering and stabilizing blood pressure magnitude of voltage is reduced to lithium battery energising voltage earlier; Lithium battery is charged; After lithium cell charging was accomplished, overload protecting circuit carried out over-charge protective to lithium battery, and overload protecting circuit also can carry out putting protection and short-circuit protection to lithium battery; Said lithium battery is through output control circuit control LED lamp; The side of housing 2 is provided with charging input interface 5; Charged state indicator lamp 6 and the change-over switch 4 that can switch the size of output control circuit power output; Light change-over switch 4 has low light level position, three positions in closed position and high light position, and the user can freely select in use, so the LED lamp can provide the way of output of the low light level and high light.

During use, the non-crystal silicon solar cell plate of the utility model Portable LED rechargeable lamp is placed on house roof or open air etc. can receives the sunshine place, connect the LED rechargeable lamp through connecting line; When solar irradiation is mapped on the non-crystal silicon solar cell plate; The non-crystal silicon solar cell plate is converted into electric energy to the inner lithium cell charging of LED lamp with luminous energy; Accomplished when the charged state indicator lamp shows charging when green, at this moment removable power line, LED lamp become the portable lighting light source; The LED lamp has by force/low light level change-over switch simultaneously, can change fast according to the actual requirements.
