Description
Technical field
The utility model relates to field of illumination lamp technology, more specifically, relates to a kind of desk lamp of multi-mode illumination.
Background technology
Desk lamp is a kind of household electrical appliance that are used for throwing light on during people live, and its operation principle is mainly that light is concentrated in a pocket, is convenient to working and learning.Wherein, the LED desk lamp be take LED (Light Emitting Diode) be light emitting diode as the desk lamp of light source, compare traditional incandescent lamp, fluorescent lamp etc. and have energy-saving and environmental protection, safe and reliable characteristics.
In prior art, the LED desk lamp partly adopts great power LED to add optical lens, have that volume is little, power consumption is little, heating is little, life-span length, fast response time, safety low-voltage, good weatherability, good directionality, can be to advantages such as non-range of exposures impact, but because light intensity is stronger, illumination range is concentrated, but sometimes more dazzling, and the long-time rear easy fatigue of eyes even is hurt.The part desk lamp adopts many low-power LED array layouts to add the even light of diffuser plate, and it has, and light intensity is weak, illumination range characteristics widely, but also because illumination range is wide, brightness of illumination is lower, easily causes light pollution and the waste of non-irradiation area.Therefore, in sum, at present the light source of LED desk lamp is certain power, and pattern is single, has a larger use restricted, causes using adaptability not enough.
The utility model content
The utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide a kind of raising using adaptability, the desk lamp of multi-mode illumination easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of desk lamp of multi-mode illumination, comprise lampshade, drain pan and control circuit, described drain pan is located on lampshade, described drain pan is provided with substrate, described real estate is provided with radiator to a side of lampshade, a described substrate side of lampshade dorsad is provided with the LED chip of at least two kinds of different capacities, and described LED chip is controlled by control circuit respectively.
Light source of the present utility model has at least two kinds of different power, therefore can carry out model selection according to use occasion.When the needs spotlighting, can select the LED chip of relatively high power to add the mode of operation of optical lens; Otherwise, when the needs floodlighting, can select the LED chip of smaller power to add the mode of operation of diffuser plate.Therefore, the utlity model has wider using adaptability, same desk lamp has different mode, is user-friendly to.
In one embodiment, described LED chip comprises at least a high-power LED chip and at least a low-power LED chip.Because great power LED and low-power LED are the general technical terms of those skilled in the art, here its definition is no longer given unnecessary details.Wherein high-power LED chip is used for the occasion of spotlighting, and being applicable to the reading of fine work or the head of a bed does not affect other people's state such as sleep; The low-power LED chip is used for the occasion of floodlighting, for example generally writes and common duty.
Because the illuminance of great power LED is strong, illumination range is concentrated; The illuminance of low-power LED is weak, illumination range is extensive, and therefore preferably, described high-power LED chip is located at the central authorities of substrate, and described low-power LED chip is arranged around high-power LED chip.
More preferably, a described high-power LED chip side of substrate dorsad is provided with optical lens, and a described low-power LED chip side of substrate dorsad is provided with diffusion sheet.Optical lens is mainly used in the optically focused of LED cold light source series of products, and leaded light can by increasing optical reflection, reduce light loss according to the angle design distribution curve flux of different LED emergent light, improves light efficiency.The light that diffusion sheet can make LED chip send evenly appears.
In one embodiment, be provided with decorative element for lamp between the LED chip of different capacity, work to intercept two kinds of light sources, and improve aesthetic property and the competitiveness of product, more can attract consumer's sight.
The beneficial effects of the utility model are: light source of the present utility model has at least two kinds of different power, therefore can carry out model selection according to use occasion.When the needs spotlighting, can select the LED chip of relatively high power to add the mode of operation of optical lens; Otherwise, when the needs floodlighting, can select the LED chip of smaller power to add the mode of operation of diffuser plate.Therefore, the utlity model has wider using adaptability, same desk lamp has different mode, is user-friendly to.
