Description
technical field:
The utility model is relevant with classroom lamp.
background technology:
The combined type classroom lamp lamp body two ends of existing band diffuser and installing plate 3 clamping, part and reflecting plate 2 clamping between lamp body two ends, be connected with involute reflecting surface 1 on the left of lamp body, be connected with involute reflecting surface 1 on the right side of lamp body, installing plate 3 is connected with lamp socket 11, and lamp socket 11 is connected with fluorescent tube 12, and diffuser 7 is u shape, above it, the tongue of both sides snaps in the caulking groove 18 of reflecting plate 2 both sides, and fluorescent tube 12 is positioned at diffuser 7.Fluorescent tube becomes 90o angle with blackboard.Diffuser 7 can not block the direct light of 40o view directions, and type unified glare exponential quantity can not be made lower than 16.
utility model content:
The purpose of this utility model is to provide a kind of direct light that can block 40o view directions, and type unified glare exponential quantity is lower than the band diffuser of 16 and the combined type classroom lamp of shadow shield.
The utility model is achieved in that
With the combined type classroom lamp of diffuser and shadow shield, lamp body two ends and installing plate 3 clamping, part and reflecting plate 2 clamping between lamp body two ends, the left and right sides of lamp body is connected with symmetrical involute reflecting surface 1, installing plate 3 is connected with lamp socket 11, lamp socket 11 is connected with fluorescent tube 12, the U-shaped cover that diffuser 7 is made for transparent material, above diffuser, the tongue of both sides snaps in the caulking groove 18 of reflecting plate 2 both sides, fluorescent tube 12 is positioned at diffuser 7, there is inside O shape groove the lower end of the involute reflecting surface 1 of the fluorescent tube section side of lamp body, shadow shield 6 is vertical dull and stereotyped, shadow shield and fluorescent tube isometric, there is outside flanging its upper end, flanging end is cylinder 19, the cylinder 19 of flanging end is positioned at the O shape groove 20 of the lower end of reflecting surface 1, the tangent line of the lower end of the connection shadow shield 6 of diffuser 7 and horizontal angle are 40o.
Lamp body is divided into upper and lower cavity by dividing plate 14, and epicoele is connected with upper cover 5, and lower chamber is connected with installing plate 3, reflecting plate 2, and upper cavity is outside line cable tray, and lower chamber is interior lines cable tray; The both sides of the chest 15 of dividing plate clamp binding post 16.
Lamp body is connected with suspender member 9, and suspender member is connected with suspension rod 10.
Advantage of the present utility model:
O shape groove 20 is had on the downside of lamp body, shadow shield 6(only fluorescent tube section is inserted) at O shape groove 20, the angle that shadow shield and diffuser tangent line are formed is 40o, in order to stop the direct light of the 40o view directions that fluorescent tube sends, now put into practice in engineering, type unified glare exponential quantity reaches 15.7 after tested, lower than 16.
accompanying drawing illustrates:
Fig. 1 is the utility model structure chart.
Fig. 2 is A-A sectional view of Fig. 1.
Fig. 3 is B-B sectional view of Fig. 1.
detailed description of the invention:
With the combined type classroom lamp of diffuser and shadow shield, lamp body two ends and installing plate 3 clamping, part and reflecting plate 2 clamping between lamp body two ends, the left and right sides of lamp body is connected with symmetrical involute reflecting surface 1, installing plate 3 is connected with lamp socket 11, lamp socket 11 is connected with fluorescent tube 12, the U-shaped cover that diffuser 7 is made for transparent material, above diffuser, the tongue of both sides snaps in the caulking groove 18 of reflecting plate 2 both sides, fluorescent tube 12 is positioned at diffuser 7, there is inside O shape groove the lower end of the involute reflecting surface 1 of the fluorescent tube section side of lamp body, shadow shield 6 is vertical dull and stereotyped, shadow shield and fluorescent tube isometric, there is outside flanging its upper end, flanging end is cylinder 19, the cylinder 19 of flanging end is positioned at the O shape groove 20 of the lower end of reflecting surface 1, the tangent line of the lower end of the connection shadow shield 6 of diffuser 7 and horizontal angle are 40o.
Lamp body is divided into upper and lower cavity by dividing plate 14, and epicoele is connected with upper cover 5, and lower chamber is connected with installing plate 3, reflecting plate 2, and upper cavity is outside line cable tray, and lower chamber is interior lines cable tray, and the both sides of the chest 15 of dividing plate clamp binding post 16.
Lamp body is connected with suspender member 9, and suspender member is connected with suspension rod 10.
The utility model has following features:
1. integral combination type structure: the integrated fabricated structure of combined type classroom lamp of band diffuser and shadow shield, lamp body may be combined with into any long o, and fluorescent tube is 2-4.
