The upper portion of radiator is equipped with the sliding tray, the top of sliding tray is equipped with the jib mount, the jib mount passes through bolt and nut fixed connection with the sliding tray, the fixed jib that is equipped with on the jib mount, the upper portion of jib is fixed on the mount of ceiling or eminence.
The upper part of the suspender is provided with a protective cover which is in a bowl shape of an upper buckle.
The protective cover is fixed on the upper part of the hanging rod through threads or fixed on a ceiling or a high fixing frame through bolts.
The suspender is a telescopic suspender, and an adjustable nut is arranged on the telescopic suspender.
The lower end of the suspender is provided with threads, the suspender fixing frame is provided with a round hole, and the lower end of the suspender passes through the round hole on the suspender fixing frame and is fixed on the suspender fixing frame through two nuts respectively arranged above and below the suspender fixing frame.
The lower end part of the suspension rod and the body part of the suspension rod are designed in a split mode, and the lower end part of the suspension rod and the body part of the suspension rod are fixedly connected through a connecting nut or a rotatable joint.
And plugs are arranged at the front end and the rear end of the heat radiation body.
And a power supply is arranged in the cavity at the right part of the heat radiation body and is fixed in the cavity at the right part of the heat radiation body through a power supply fixing support.
The material of polarized lens is ya keli or PC, and its lower part is for going out the plain noodles, polarized lens's inside adopts irregular polarisation design, it designs for the plane to go out the plain noodles.
The utility model has the advantages that: the heat radiation body is designed into an integrated hollow strip shape, so that the heat radiation body is light, simple and firm, and is quick and convenient to install; the hanger rod is in a telescopic design, so that the height of the blackboard lamp can be conveniently adjusted, and the angle of the lamp body irradiating the blackboard can be further adjusted by the rotary joint, so that light on the blackboard is more comfortable and softer; because the inside of the polarized lens adopts the irregular polarized light design, and the light-emitting surface is designed to be a plane, the polarized lens can effectively irradiate light on the blackboard, can well prevent glare while ensuring that the illumination of the blackboard reaches 500lx and the uniformity is more than 0.8, and can effectively reduce the input power of the lamp, thereby achieving the purposes of saving energy and electricity.
