Abstract
The utility model relates to a touch type light-adjustable desk lamp, which includes a base (1), a connecting unit (2), a cover body (3) and an LED lamp (4); the desk lamp further includes a light-adjustable device (5) arranged on the base (1); the connecting unit (2) is used for connecting the base (1) and the cover body (3); and the LED lamp (4) is arranged in the cover body (3). Through the light-adjustable device arranged on the base of the desk lamp, people's different requirements on light intensity can be met, and the desk lamp saves electricity and protects environment.
Description
Technical field
The utility model relates to a kind of desk lamp, and particularly relating to a kind of light intensity can be by the touch tunable optical desk lamp of the tunable optical device flexible modulation on the pedestal.
Background technology
Illuminating ray, the illuminating ray when especially reading too by force or that eyes are produced is tired, cause that easily eyesight descends, particularly to students in middle and primary schools.Existing lamp dimmer mostly is that irradiation brightness is adjusted in the moving light modulation of armrest, and can only reaches certain fixedly light intensity.When this when fixedly light intensity is too strong, this mode also can consume the too much energy when may destroying people's eyesight; When this when fixedly light intensity is too weak, this mode may influence people's eyesight, people may reach the purpose that light intensity strengthens by changing more powerful bulb simultaneously, and because people constantly may be to the requirement difference of light intensity, so improve along with the raising of people's living standard for the requirement meeting that changes a little less than the light intensity in difference.
More common on the market desk lamp mainly be divided into utilize CCFL and incandescent lamp desk lamp form, the characteristic of this kind desk lamp to be with low cost for light emitting source and color rendering good etc.; But shortcoming is the long-time high heat that is produced of using can shorten its life-span, and therefore life cycle also reduces.The environmental issue that has more in the waste treatment in addition to be produced.
(Light Emitting Diode is LED) because characteristics such as its reaction speed is fast, volume is little, low power consumption, low in calories, long service life replace traditional lighting light fixtures such as incandescent lamp bulb and Halogen lamp LED to light emitting diode gradually.
The LED desk lamp of commercially available employing direct current supply, its power supply are general dry battery or rechargeable battery, are saves energy, and the effective amount of LED is few, and brightness is limited can't be regulated, and can not satisfy the needs of highlight illumination requirement.The LED desk lamp of commercially available employing Alternating Current Power Supply, adopt civil power to supply with for saving its power supply of cost through the resistance-capacitance depressurization circuit, the effective amount of LED is many, brightness is big, but can't regulate when needing the low-light level illumination, not only reactive loss is big for this step-down mode, and line-to-earth voltage is still the 220V civil power in galvanization simultaneously, can bring certain hidden danger to the personal safety meeting when damaging if any fluorescent tube.
The utility model content
At the problems referred to above, main purpose of the present utility model is to provide a kind of light intensity can be by the touch tunable optical desk lamp of the tunable optical device flexible modulation on the pedestal.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of touch tunable optical desk lamp, described desk lamp comprises pedestal, linkage unit, cover body, LED lamp, described desk lamp also comprise a tunable optical device, and the tunable optical device is located on the described pedestal, described linkage unit connects described pedestal and cover body, and described LED lamp is arranged in the cover body.
In specific embodiment of the present utility model, described tunable optical device is a rotary switch.
In specific embodiment of the present utility model, described tunable optical device is a switching switch.
In specific embodiment of the present utility model, described tunable optical device is a multisection type change-over switch.
Positive progressive effect of the present utility model is: the tangibly tunable optical desk lamp that the utility model provides has the following advantages: the utility model can overcome following defective by the tunable optical device that is installed on the desk lamp pedestal: the illuminating ray when reading, too by force or that eyes are produced is tired, cause that easily eyesight descends, particularly to students in middle and primary schools, and existing lamp dimmer, mostly be that irradiation brightness is adjusted in the moving light modulation of armrest, and can only reach certain fixedly light intensity, when this when fixedly light intensity is too strong, this mode also can consume the too much energy when may destroying people's eyesight; When this when fixedly light intensity is too weak, this mode may influence people's eyesight, people may reach the purpose that light intensity strengthens by changing more powerful bulb simultaneously, and because people constantly may be to the requirement difference of light intensity in difference.
Description of drawings
Fig. 1 is one of structural representation of the present utility model.
Fig. 2 is two of a structural representation of the present utility model.
Fig. 3 is three of a structural representation of the present utility model.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Fig. 1 is one of structural representation of the present utility model, the utility model comprises pedestal 1, linkage unit 2, cover body 3, LED lamp 4, described desk lamp also comprise a tunable optical device 5, and tunable optical device 5 is located on the described pedestal 1, described linkage unit 2 connects described pedestal 1 and cover body 3, and described LED lamp 4 is arranged in the cover body 3.Illuminating ray when reading, too by force or that eyes are produced is tired, cause that easily eyesight descends, particularly to students in middle and primary schools, and existing lamp dimmer mostly is that irradiation brightness is adjusted in the moving light modulation of armrest, and can only reach certain fixedly light intensity, when this when fixedly light intensity is too strong, this mode also can consume the too much energy when may destroying people's eyesight; When this when fixedly light intensity is too weak, this mode may influence people's eyesight, people may reach the purpose that light intensity strengthens by changing more powerful bulb simultaneously, and because people constantly may be to the requirement difference of light intensity in difference.
In first specific embodiment of the present utility model, described tunable optical device 5 is a rotary switch.Fig. 2 is two of a structural representation of the present utility model, and in this specific embodiment of the present utility model, tunable optical device 5 is a switching switch.
Fig. 3 is three of a structural representation of the present utility model, and in this specific embodiment of the present utility model, tunable optical device 5 is a multisection type change-over switch.
Compare with preceding two examples of implementation of the present utility model, the 3rd examples of implementation are optimum examples of implementation, can regulate tunable optical device 5 and reach different light intensity and more select.
