Abstract
The utility model relates to the technical field of illumination lamps and aims to provide a table lamp with an adjustable color temperature, wherein the table lamp with the adjustable color temperature is simple and reasonable in structure and capable of lowering production cost. The table lamp with the adjustable color temperature comprises a supporting base which is provided with a substrate and a control circuit. The substrate is provided with at least two kinds of white light LED chips with different color temperatures. The white light LED chips are controlled by the control circuit respectively. According to the table lamp with the adjustable color temperature, at least two kinds of the white light LED chips with the different color temperatures are arranged and controlled by the control circuit respectively, and white light with the different color temperatures is synthesized through driving currents of the control circuit. Therefore, the table lamp with the adjustable color temperature is simple and reasonable in structure and low in production cost, and has broader use adaptability; the different color temperatures can be obtained by the same table lamp through adjustment, so that convenience is brought to use by a user.
Description
Technical field
The utility model relates to field of illumination lamp technology, more specifically, relates to a kind of desk lamp of adjustable color temperature.
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 is to be the desk lamp of light emitting diode as light source take LED (Light Emitting Diode), compares traditional incandescent lamp, fluorescent lamp etc. and has energy-saving and environmental protection, safe and reliable characteristics.
In prior art, colour temperature means the yardstick that light source is photochromic, means the most general index of light source light spectrum quality.Light source color temperature is different, and photochromic different, the sensation of bringing is not identical yet yet.Therefore, sometimes need the colour temperature of light source is regulated.Yet due to concerning single white light LEDs, its colour temperature is changeless, and therefore present LED desk lamp scarcely can be regulated colour temperature.
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 simple and reasonable, the desk lamp of the adjustable color temperature that reduces production costs.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of desk lamp of adjustable color temperature, comprise supporting seat, described supporting seat is provided with substrate and control circuit, described substrate is provided with the White-light LED chip of at least two kinds of different-colours, and described White-light LED chip is controlled by control circuit respectively.
The utility model is provided with the White-light LED chip of at least two kinds of different-colours, controlled by control circuit respectively, the white light that synthesizes different-colour by the drive current of control circuit, simple and reasonable, production cost is low, and have wider using adaptability, same desk lamp can obtain different-colour by adjusting, is user-friendly to.
In one embodiment, described White-light LED chip comprises the White-light LED chip of at least a high color temperature and the White-light LED chip of at least a low colour temperature, thereby can increase the adjustable range of colour temperature in the utility model, and then has wider using adaptability.Preferably, described White-light LED chip is array distribution on substrate, arrange neat, and luminous concentrating evenly.Certainly, in other embodiments, described White-light LED chip can also be other Central Symmetries and distribute on substrate, such as annular spread etc.
In an embodiment of the present utility model, in the middle of the White-light LED chip of described low colour temperature was located at, the White-light LED chip of described high color temperature was located at both sides.In another embodiment of the present utility model, the White-light LED chip of described low colour temperature and the White-light LED chip of high color temperature are alternately arranged successively.
In a preferred embodiment, a described White-light LED chip side of substrate dorsad is provided with diffusion sheet.The light that diffusion sheet can make White-light LED chip send evenly appears.
In one embodiment, the structure of described supporting seat for folding.For example supporting seat is formed by hinged by some gripper shoes, thereby can fold or partially folded.Can supporting seat is fully folding when not using, dwindle shape.Also can regulate by folding as required in use, be user-friendly to.
The beneficial effects of the utility model are: the utility model is provided with the White-light LED chip of at least two kinds of different-colours, controlled by control circuit respectively, the white light that synthesizes different-colour by the drive current of control circuit, simple and reasonable, production cost is low, and have wider using adaptability, same desk lamp can obtain different-colour by adjusting, is user-friendly to.
