Description
Technical field
The utility model relates to a kind of lighting, particularly a kind of LED desk lamp.
Background technology
Desk lamp is that working and studying is indispensable lighting, particularly be in the student of middle school period, usually under desk lamp, learn, the light emitting source of existing desk lamp adopts common bulb or energy-saving bulb usually, because these desk lamps all use alternating current as power supply, so, light instability when bulb is luminous, have stroboscopic, bigger to people's eyesight influence, study or work are easy to cause myopia under this light for a long time.Though there are some desk lamps to adopt the LED light emitting diode as light source,, the light that directly sends with the LED light emitting diode throws light on often, because the LED light-emitting diode luminance is higher, the light that sends is more dazzling, and is therefore, also influential to people's eyesight.
Summary of the invention
The purpose of this utility model be at the existing desk lamp described in the background technology exist to the influential problem of people's eyesight, a kind of LED desk lamp that can solve foregoing problems is provided.
The technical scheme that realizes goal of the invention of the present utility model is as follows:
A kind of LED desk lamp, it comprises lamp socket, constant-current source processor, lamp holder and the bracing frame that is used to connect lamp holder and lamp socket, lamp holder comprises the fixed frame that is connected with bracing frame, the aluminium base circuit board that is provided with the LED diode chip for backlight unit and the aluminium alloy heat-dissipating casing that is connected with aluminium base circuit board, between aluminium base circuit board and fixed frame, be provided with reflector, position corresponding with the LED diode chip for backlight unit on the reflector is provided with reflective hole, is provided with the floodlight plate of PC material between reflector and the fixed frame.
Can regulate within the specific limits for the bracing frame that makes desk lamp and the angle of lamp socket, described bracing frame lower end and lamp socket flexibly connect.
In order to prevent toppling over of desk lamp, be provided with the body of casting that is used to increase lamp socket weight in the described lamp socket.
In order to prevent lamp socket bottom and desktop friction, with the desktop wearing and tearing, described lamp socket bottom is provided with cushion.
For make lamp holder axially and the footpath upwards can both rotate, make things convenient for the user to regulate the direction of light and illuminate scope, described fixed frame and bracing frame flexibly connect by cradle head.
The switching manipulation of desk lamp for convenience, and can regulate the brightness of desk lamp, described lamp socket is provided with touch-screen, and touch-screen is provided with switch bit and several brightness gears, is provided with the control chip that is connected with touch-screen in the lamp socket.
In order to improve the heat-conducting effect of LED diode chip for backlight unit, be provided with high thermal conductive silicon fat sheet between described LED diode chip for backlight unit and the aluminium base circuit board.
Flow over for convenience replacing of processor, described constant-current source processor is connected with the wiring fracture of lamp socket.
The beneficial effects of the utility model are because a kind of LED desk lamp of the present utility model, it comprises lamp socket, lamp holder and the bracing frame that is used to connect lamp holder and lamp socket, and lamp holder comprises the fixed frame that is connected with bracing frame, the aluminium base circuit board that is provided with the LED diode chip for backlight unit and the aluminium alloy heat-dissipating casing that is connected with aluminium base circuit board.When constant-current source is provided by its power connection that provides, the LED diode chip for backlight unit is luminous, the heat that produces conducts on the aluminium base circuit board, because aluminium base circuit board thermal conductivity is good, therefore can be fast with the LED diode chip for backlight unit when luminous the heat of generation conduct to the aluminium alloy heat-dissipating casing, be delivered in the surrounding air by the aluminium alloy heat-dissipating casing.Be provided with reflector between aluminium base circuit board and fixed frame, position corresponding with the LED diode chip for backlight unit on the reflector is provided with reflective hole, is provided with the floodlight plate of PC material between reflector and the fixed frame.When the LED diode chip for backlight unit was luminous, light shone on the floodlight plate by the effect of reflective hole, and through the scattering of floodlight plate, radiation direction changes, and makes light become soft not dazzling.
