Abstract
The utility model relates to an LED lamp with power supplied through USB, which comprises a lamp head, a lamp socket, a lamp post and a USB plug for supplying power. The lamp head comprises a conical chamber which is provided with a light reflection wall surface at the periphery. The LED lamp is provided at the bottom of the conical chamber. A glass window is provided at the top of the conical chamber. The lamp post can be set to a random shape and direction. The lamp socket is provided with a switch for controlling the switching-on and switching-off of the power supply. An anode of the LED lamp is connected with the switch, and a cathode is connected with a current limiting resistor. The other end of the current limiting resistor is grounded. The other end of the switch is connected with a power source VCC. The LED lamp has the following beneficial effects: adoption of cold light source, high energy utilization rate, power obtainment through the USB port of computer, high convenience, high practicability, simple structure, capacity for being placed at any position, and high suitability for the occasion with partial lighting.
Description
Technical field
The utility model relates to a kind of LED lamp of USB power supply.
Background technology
At present, the development of LED lighting engineering is very fast, and from civilian flashlight, to the monitoring, illumination of industry spot, and auto lamp all extensively adopts the LED lamp.The LED illumination has the energy utilization rate height, and caloric value is little, and the good advantage of luminous directive property.Simultaneously, LED lamp required voltage is low, drives simply, therefore can be used as the computer peripheral auxiliary facility.
Computer related work person or computer amateur can have the needs of continuous operation in evening, but the household has had a rest, if opening lamp this time, be certain to influence the household, and if the work of turning off the light, the light of computer screen will certainly influence vision, the injury eyesight, and do not see keyboard.
Summary of the invention
The utility model purpose is in order to overcome deficiency of the prior art, and a kind of employing USB power supply is provided, the basher of LED lamp illumination, and as the peripheral equipment of computer, the lighting problem that the settlement computer worker works night.
The technical scheme that its technical problem that solves the utility model adopts is:
The LED lamp of USB power supply comprises lamp holder, lamp socket and lamp stand, also comprise the USB plug that power supply is provided, described lamp holder comprises conical cavity, and reflective wall is set around the described conical cavity, the bottom of described conical cavity is provided with the LED lamp, and the top of described conical cavity is provided with windowpane.
Described lamp stand can be provided with shape and direction arbitrarily.
Described lamp socket is provided with the switch of controlling on/off.
Described LED lamp, anode connects described switch, and negative electrode connects current-limiting resistance, described current-limiting resistance other end ground connection, the described switch other end connects power supply VCC.
The beneficial effects of the utility model mainly show: 1, adopt cold light source, energy utilization rate height; 2, utilize the USB port power taking of computer, convenient and practical; 3, structure is small and exquisite, and placement location arbitrarily is highly suitable for the occasion of local lighting.
Description of drawings
Fig. 1 is the front view of the LED lamp of USB power supply;
Fig. 2 is the side view of the LED lamp of USB power supply;
Fig. 3 is the circuit diagram of the LED lamp of USB power supply.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1-3, the LED lamp of USB power supply comprises lamp holder 1, and lamp socket 7 and lamp stand 6 also comprise the USB plug 8 that power supply is provided.
Described lamp holder 1 comprises conical cavity 2, around the described conical cavity 2 reflective wall 4 is set, and the bottom of described conical cavity 2 is provided with LED lamp 3, and the top of described conical cavity 2 is provided with windowpane 5.Produce the utilization rate of illumination in order to improve described LED lamp 3, therefore at described lamp holder 1 described conical cavity 2 is set, described LED lamp 3 is arranged on the bottom of described conical cavity 2, and reflective wall 4 is set around the described conical cavity 2, the illumination meeting that described like this LED lamp 3 produces is most of outwards throws, and has improved the utilization rate of light.Be accumulated at described conical cavity 2 the insides for fear of dust; absorb the light that described LED lamp 3 produces; influence illuminating effect; described windowpane 5 is set at the top of described conical cavity 2; described windowpane 5 is a printing opacity; blocks dust again, and can play the described LED lamp 3 of protection and avoid damaging.
Described lamp stand 6 can adopt the material that shape and direction are set arbitrarily.The user can as required and be accustomed to like this, freely adjusts the zone of illumination.
Described lamp socket 7 is provided with the switch 9 of controlling on/off.By described switch 9, said LED lamp 3 can be set whether power.
Described LED lamp 3, anode connect described switch 9, and negative electrode connects current-limiting resistance 10, described current-limiting resistance 10 other end ground connection GND, and described switch 9 other ends connect power supply VCC.Described power supply VCC and ground GND are provided by described USB plug 8.
When in use, directly described USB plug 8 is inserted on the USB interface of computer, opens described switch 9 then and just can obtain illumination.
In sum, the utility model provides a kind of employing USB power supply, the basher of LED lamp illumination, have the energy utilization rate height, utilize the USB port power taking of computer, convenient and practical, and structure is small and exquisite, and placement location arbitrarily is highly suitable for the occasion of local lighting.
