Abstract
The utility model discloses a kind of blackboard light fixture, include the lamp housing that end face takes the shape of the letter U, fasten and be welded on the bottom below lamp housing, fasten and be welded on two end caps at lamp housing both ends, be bolted two Connection Blocks near position, both ends on bottom, the fluorescent tube being plugged on the lamp socket on Connection Block and being arranged between two lamp sockets; In described lamp housing, ballast is installed; Described end cap lower end forms the brace of a L shape, and brace has been connected by screw adjuster, is connected with a lampshade between two adjusters, and described lamp socket stretches within described lampshade, and fluorescent tube is in below described lampshade; Be provided with stepper motor in described adjuster, the output shaft of stepper motor is connected with described lampshade.Rotated by two driving stepper motor lampshades thus irradiating angle is changed, can adjust flexibly according to the light in classroom.Because stepper motor only drives lampshade to rotate, the moment of torsion of needs is little, low in energy consumption.
Description
Technical field
The utility model belongs to field of light fittings, is specifically related to a kind of blackboard lights lamps structure.
Background technology
The lampshade of existing blackboard light fixture is all fixing, and when mounted lamp, lampshade angle is also just decided, and can not regulate, result of use is undesirable.Some can the blackboard light fixture of adjusting angle be then fluorescent tube, control circuit etc. are all integrally rotated, and need the motor that power is larger, cost is high.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, and provide a kind of structure simple, parts are few, easy for installation, are beneficial to the blackboard light fixture of adjustment lampshade angle.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of blackboard light fixture, include the lamp housing that end face takes the shape of the letter U, fasten and be welded on the bottom below lamp housing, fasten and be welded on two end caps at lamp housing both ends, be bolted two Connection Blocks near position, both ends on bottom, the fluorescent tube being plugged on the lamp socket on Connection Block and being arranged between two lamp sockets; In described lamp housing, ballast is installed; Described end cap lower end forms the brace of a L shape, and brace has been connected by screw adjuster, is connected with a lampshade between two adjusters, and described lamp socket stretches within described lampshade, and fluorescent tube is in below described lampshade; Be provided with stepper motor in described adjuster, the output shaft of stepper motor is connected with described lampshade; Described lampshade includes the outer cover of a metal material and is connected to the reflector of the plastic material below outer cover, and the inner surface of reflector is coated with reflective material layer; Described outer cover top is downward opening U-shaped, and the both sides of outer cover are curved, and the both ends of outer cover are welded with two end shields; Described reflector is by integrally moulded, and described reflector end face is curved, forms multiple joint pin above reflector, and joint pin is connected by screw the top at outer cover; Described reflector outer surface forms the reinforcement parallel with reflector end face.
Preferably: described lamp housing upper wall surface forms a strip groove, offers the opening of U-shaped in strip groove, form a link plate in U-shaped opening, link plate has hanging hole; Lamp housing upper wall surface is positioned at strip groove both sides and offers multiple installation connecting hole.Described link plate is convenient to light fixture to hang, described installation connecting hole is convenient to be connected by screw by light fixture on ceiling or body of wall, installation form is available, and during by installing connecting hole mounted lamp, due to the existence of strip groove, even if metope exists upper wall surface and the body of wall good fit that slight out-of-flatness also can ensure lamp housing preferably.
Preferably: the both sides of described end cap and downside bending forming have three grafting walls, grafting wall to insert in lamp housing and is welded and fixed with lamp housing.Described end cap and lamp housing are connected firmly, and are beneficial to the installation of adjuster and lampshade.
Compared with prior art, the beneficial effects of the utility model are: rotated by two driving stepper motor lampshades thus irradiating angle is changed, can adjust flexibly according to the light in classroom.Because stepper motor only drives lampshade to rotate, the moment of torsion of needs is little, low in energy consumption, and use the stepper motor of 5V or 12V to realize, cost is low.Described reflector is plastic material, facilitates one machine-shaping and is convenient to process smooth arcuate shape, being beneficial to the reflection of light.

Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to shown in Fig. 1 to Fig. 5, a kind of blackboard light fixture described in the present embodiment, include the lamp housing 1 that end face takes the shape of the letter U, fasten and be welded on the bottom 14 below lamp housing, fasten and be welded on two end caps 11 at lamp housing both ends, be bolted two Connection Blocks 15 near position, both ends on bottom, the fluorescent tube 4 being plugged on the lamp socket 16 on Connection Block and being arranged between two lamp sockets; Ballast 5 is installed in described lamp housing; Described end cap lower end forms the brace 112 of a L shape, brace has been connected by screw adjuster 2, is connected with a lampshade 3 between two adjusters, and described lamp socket stretches within described lampshade, and fluorescent tube is in below described lampshade; Be provided with stepper motor in described adjuster, the output shaft of stepper motor is connected with described lampshade; Described lampshade includes the outer cover 31 of a metal material and is connected to the reflector 32 of the plastic material below outer cover, and the inner surface of reflector is coated with reflective material layer; Described outer cover top is downward opening U-shaped, and the both sides of outer cover are curved, and the both ends of outer cover are welded with two end shields 311; Described reflector is by integrally moulded, and described reflector end face is curved, and form multiple joint pin 322 above reflector, joint pin is connected by screw the top at outer cover; Described reflector outer surface forms the reinforcement 321 parallel with reflector end face.
