Abstract

The utility model discloses an adjustable desk lamp of colour temperature, include rectangular shape shell, arrange in bar fluorescent tube and cover in the shell are located lamp shade on the shell, a serial communication port, the shell including the end wall that is located the tip, the end wall internal surface is followed shell length direction is equipped with the fluorescent tube, the fluorescent tube cover is equipped with cylinder filter cover, the end wall surface is equipped with steerable filter cover axial rotation's knob. The utility model discloses an adjustable desk lamp of colour temperature is through establishing cylindric filter cover at the fluorescent tube overcoat to set up the knob and be used for rotatory filter cover, make lamps and lanterns through presenting different colour temperature effects.

Description

A kind of adjustable color desk lamp

Technical field

This utility model belongs to field of light fittings, relates to a kind of adjustable color desk lamp.

Background technology

The light source of the conventional light fixture of great majority is unique, so light fixture is typically only capable to the light beam of a kind of colour temperature of outgoing, and along with living standard improves, people propose further demand to light fixture colour temperature, as in Same Scene, different time or different application scene need different light fixture colour temperatures to meet diversified demand, it is clear that conventional monochromatic temperature light fixture cannot meet this demand.

For this phenomenon, occur in that the adjustable light fixture of different-colour on the market, common practice is to preset the light source of multiple color temperatures in the light source part of light fixture, as LED lamp presets multiple LED particle cold, warm-toned, the even LED particle of different colours, by controlling the LED particle time-sharing work of different-colour, thus realize the light beam of the same lamp tool outgoing different-colour, use more convenient.But the light source and the increase control system that arrange multiple granule in such scheme will increase whole lamp cost, and increase system complexity thus will increase light fixture fault rate, generally use Digiplex such as control method, increase is controlled fault rate by this control mode relative mechanical switch.

Utility model content

Utility model proposes a kind of adjustable color desk lamp for technical problem present in prior art, and concrete scheme is as follows:

A kind of adjustable color desk lamp, the bar shaped fluorescent tube that including strip shell, is placed in described shell and cover at the lampshade on described shell, it is characterized in that, described shell includes the end wall being positioned at end, described end wall inner surface is provided with fluorescent tube along described outer cover length direction, described light tube jacket is provided with cylindrical shape shade, and described end wall outer surface is provided with the knob that can control described shade axial-rotation.

In such scheme, fluorescent tube is fixed on the arcuate groove on shell end wall, arcuate groove with end wall outside knob fixing is connected, the arcuate groove on fluorescent tube and end wall is fixing connect after, the knob i.e. rotatable lamp tubes outside rotation end wall.Fluorescent tube goes out light and light towards outer casing inner wall and goes out light towards lampshade and make light fixture present different light-out effect on the whole: when fluorescent tube light direction is towards outer casing inner wall, and light beam is reflective through outer casing inner wall and reflexes to lampshade and transmits light；When fluorescent tube light direction is towards lampshade, light beam first passes around the shade below fluorescent tube, light beam filtered cover optical filtering transmits light after processing, the light beam of outgoing different-colour after the filtered process of light beam can be made by selecting the shade of different-effect during Gai, thus reach the purpose of adjustable color.

As preferably, described shade is provided with several ray filtering material.In the different angles of the circular cross-section that ray filtering material is distributed in tubular shade, be distributed in striated, i.e. shade does not rotates an angle, and the most convertible once optical filtering of fluorescent tube outgoing beam processes, thus it is adjustable to realize multiple color temperatures.

Compared with prior art, this utility model has the advantage that a kind of adjustable color desk lamp of the present utility model, by sheathed tubular shade outside fluorescent tube, and arranges knob for rotating filtering cover so that light fixture is by presenting different colour temperature effects.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of a kind of adjustable color desk lamp of this utility model embodiment；

Fig. 2 is fluorescent tube and the shade attachment structure schematic diagram of a kind of adjustable color desk lamp of this utility model embodiment.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in further detail.

A kind of adjustable color desk lamp of this utility model embodiment, the bar shaped fluorescent tube 2 that including strip shell 1, is placed in shell 1 and cover at the lampshade 3 on shell 1, shell 1 includes the end wall 11 being positioned at end, end wall 11 inner surface is provided with fluorescent tube 2 along shell 1 length direction, fluorescent tube 2 is arranged with cylindrical shape shade 4, and end wall 11 outer surface is provided with the knob 5 that can control shade 4 axial-rotation.Wherein, shade 4 is provided with several ray filtering material.

Above-mentioned a kind of adjustable color desk lamp, the shade 4 in end wall 11 can be driven to rotate by the knob 5 outside rotation end wall 11, and colour temperature changes after filtered cover 4 optical filtering of fluorescent tube 2 outgoing beam processes, and after shade 4 rotates, on the filtered cover of light 2 outgoing beam 4, the ray filtering material optical filtering of zones of different can realize the light beam of desk lamp outgoing different-colour after processing, thus realizes desk lamp adjustable color.

The technical solution of the utility model and beneficial effect have been described in detail by above-described detailed description of the invention; it it should be understood that and the foregoing is only most preferred embodiment of the present utility model; it is not limited to this utility model; all made in spirit of the present utility model any amendment, supplement and equivalent etc., within should be included in protection domain of the present utility model.

Claims

1. an adjustable color desk lamp, the bar shaped fluorescent tube that including strip shell, is placed in described shell and cover at the lampshade on described shell, it is characterized in that, described shell includes the end wall being positioned at end, described end wall inner surface is provided with fluorescent tube along described outer cover length direction, described light tube jacket is provided with cylindrical shape shade, and described end wall outer surface is provided with the knob that can control described shade axial-rotation.

A kind of adjustable color desk lamp the most according to claim 1, it is characterised in that described shade is provided with several ray filtering material.
