Description

The desk lamp of adjustable brightness joint
Technical field
The utility model relates to a kind of desk lamp, specifically is a kind of desk lamp of adjustable brightness joint.
Background technology
Desk lamp is as a kind of common illuminations, and is very popular.For satisfying people's user demand, the pattern of desk lamp and function all develop to diversified direction.The desk lamp that the desk lamp that can give the correct time, telescopic desk lamp, the adjustable desk lamp of irradiating angle and adjustable brightness joint are arranged that occurs in the market etc. all is well received by consumers.The intensity adjustable desk lamp of prior art, its structure generally comprises lamp stand, support, lampshade, socket and bulb, described socket live wire is connected with brightness regulating apparatus, transformer positive pole through lead, the socket zero line is connected with negative pole, transformer is connected with power supply wiring, described brightness regulating apparatus is made up of rotary switch and resistance adjustment structure, regulates the brightness of bulb by the resistance value between adjusting bulb and the power supply wiring.Its adjustment structure more complicated of the intensity adjustable desk lamp of this structure, cost is higher.In addition, regulate in the process of the resistance value between bulb and the power supply wiring,, damage bulb easily, shorten the service life of bulb if governing speed is too fast.
The utility model content
The technical problems to be solved in the utility model is to overcome the defective of above prior art, the desk lamp that provides a kind of adjustable brightness simple in structure, long service life to save.
Technical solution of the present utility model is, a kind of desk lamp with adjustable brightness joint of following structure is provided: it comprises bulb, bearing, cylindric lampshade, power supply wiring, the outer wall of described lampshade is provided with lampshade and blocks housing, and described lampshade blocks housing and lampshade is spirally connected.
After adopting above structure, the desk lamp of the utility model adjustable brightness joint compared with prior art, have the following advantages: the outer wall of lampshade is provided with lampshade and blocks housing, when regulating desk lamp brightness, rotary lampshade blocks housing and blocks the brightness of how much regulating desk lamp that housing blocks lampshade by lampshade, thereby realizes the adjustable brightness of desk lamp.It is simple in structure for the desk lamp of this adjustable brightness joint, and cost is lower.When regulating desk lamp brightness in addition, do not need to regulate the resistance value between bulb and the power supply wiring, thereby reduce to bulb the influence when luminous, thereby the desk lamp service life of the adjustable brightness of this structure joint.
Description of drawings
It shown in the figure structural representation of the desk lamp of the utility model adjustable brightness joint.
As shown in the figure:
1, lampshade blocks housing, and 2, bayonet socket, 3, lampshade, 4, bulb, 5, projection, 6, bearing, 7, power supply wiring.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in the figure as can be known, the desk lamp of the utility model adjustable brightness joint, it comprises bulb 4, bearing 6, cylindric lampshade 3, power supply wiring 7, and the outer wall of described lampshade 3 is provided with lampshade and blocks housing 1, and described lampshade blocks housing 1 and is spirally connected with lampshade 3.
Described being spirally connected is meant that the outer wall of described lampshade 3 is provided with screw-like projection 5, and described lampshade blocks housing 1 and is provided with the screw-like bayonet socket 2 that matches with screw-like projection 5, and described protruding 5 width is not more than the height of bayonet socket 2.
Described lampshade blocks housing 1 and blocks housing for light tight lampshade.
The operation principle of the desk lamp of the utility model adjustable brightness joint: when regulating desk lamp brightness, rotary lampshade blocks housing 1 and blocks the brightness of how much regulating desk lamp that housing 1 blocks lampshade 3 by lampshade, thereby realizes the adjustable brightness of desk lamp.
