Conventionally, as shown in FIG. 4, a blackboard light 50 that illuminates a blackboard surface has a large amount of chalk attached to the lamp 54 and reflector 56 inside the device body 52 due to its intended use, resulting in a significant decrease in device efficiency. was causing Therefore, in order to maintain the brightness of the blackboard surface, frequent cleaning is required. However, blackboard light 50
are installed in high places, and students in elementary and junior high schools had to climb on desks and chairs to remove chalk powder from the lamps 54 and reflectors 56. in this way,
The work of removing chalk powder that had entered the inside of the equipment was extremely troublesome. Note that FIG. 5 is a side view of the main body of the blackboard lamp.

The blackboard 10 is provided in front of a wall 12 via a mounting base 14. Further, the blackboard light is composed of a power supply section 16 provided on the back surface of the blackboard 10, and a lamp section 20 installed in front and above the blackboard 10 via an arm 18. A ballast and a terminal block are housed in the power supply unit 16, and the arm 18 is connected to the blackboard 10.

上げても眩しくない角度に保たれている。 Further, the lamp section 20 is configured as shown in FIG. In the figure, 22 is a front end portion 22a.
The main body of the lamp has an illumination opening 24 which is sharply pointed and opened at an angle facing the blackboard 10. A lamp socket 32 supported by a support 34 is provided inside the lamp body 22, and the lamp socket 32 is supported by a support 34.
A lamp 30 is attached to 2. Further, a reflecting plate 28 is disposed closer to the front end 22a than the lamp socket 32, and the reflecting plate 28 is installed between the supporting protrusion 26 and the front end 22a.
Further, mounting grooves 36 and 38 are formed in the lamp body 22 at the upper and lower edges of the illumination opening 24. Both side edges 40a, 4 are attached to the mounting grooves 36, 38.
0b is inserted, and the transparent plate 40 is attached in a diagonally downward position. The transparent plate 40 has an upper side edge 4
Lower side edge 4 after inserting 0a into the mounting groove 36
0b is inserted into the mounting groove 38 for installation. The angle of inclination of the light-transmitting plate 40 is maintained at an angle that does not dazzle even if, for example, students in the front row of the classroom look up at the upper end of the blackboard 10.

く、清掃作業が簡単で小学生でも安全に作業でき
る。 According to the blackboard light constructed in this way, since the diagonally downward illumination opening 24 of the lamp body 22 is covered with the transparent plate 40, the lamp 30 and the reflector 28 inside the lamp body 22 are not contaminated. In addition, by arranging the light-transmitting plate 40 in an obliquely downward position, the outer surface 40d of the light-transmitting plate 40 faces downward, making it difficult for chalk powder to adhere to it, and thus reducing the reduction in efficiency of the blackboard lamp. Even if powder is attached,
The chalk powder only electrostatically adheres to the smooth outer surface 40d of the transparent plate 40, and cleaning only needs to remove the chalk powder attached to the outer surface 40d of the transparent plate 40, making the cleaning work easy. Even elementary school students can work safely.
また、透光板４０は上下縁部４０ａ，４０ｂを
取付溝３６，３８に挿入してあるだけなので、簡
単に着脱でき、反射板２８もランプソケツト３２

いるので、ランプソケツト３２にじやまされず簡
単に着脱できる。したがつて、灯具本体２２内の
清掃やランプ交換等のメンテナンスが容易に行え
る。 Further, since the upper and lower edges 40a and 40b of the transparent plate 40 are simply inserted into the mounting grooves 36 and 38, it can be easily attached and detached, and the reflector plate 28 can also be attached to the lamp socket 32.
Since it is disposed closer to the front end 22a of the lamp body 22, it can be easily attached and detached without being hindered by the lamp socket 32. Therefore, maintenance such as cleaning the inside of the lamp body 22 and replacing the lamp can be easily performed.
また、灯具本体２２の前端部２２ａが尖つてい
るので、前方から灯具本体２２を見上げた際に薄
く感じ重圧感がなく、学習意欲が向上する。 In addition, since the front end 22a of the lamp body 22 is sharp, when looking up at the lamp body 22 from the front, it feels thin and does not give a feeling of pressure, which improves the student's motivation to learn.
さらに、電源部１６を灯具部２０から離して黒
板１０の裏側に配置したので、灯具部２０自身が
薄くなる。このため、例えば第３図に示すよう
に、黒板１０の上方の掲示板を見る場合、第５図
に示したような従来の照明器具を取付けた時には
照明器具による死角幅がＬとなるのに対し、本実
施例の黒板灯によるとその死角幅がｌ（≒0.89L）
となり、黒板１０の上方の掲示板が見易くなる。 Furthermore, since the power source section 16 is placed away from the lamp section 20 and on the back side of the blackboard 10, the lamp section 20 itself becomes thinner. For this reason, when looking at the bulletin board above the blackboard 10, as shown in Figure 3, for example, the blind spot width due to the lighting equipment is L, whereas when conventional lighting equipment as shown in Figure 5 is installed, the blind spot width due to the lighting equipment is L. According to the blackboard light of this example, the blind spot width is l (≒0.89L)
Therefore, the bulletin board above the blackboard 10 becomes easier to see.
なお、透光板４０を導電性（比抵抗が10-9Ω・
cm以下）にすると、白墨粉が静電的に付着し難く
なり、器具効率の低下がより一層緩和できる。 Note that the transparent plate 40 is conductive (specific resistance is 10 -9 Ω・
cm), it becomes difficult for chalk powder to adhere electrostatically, and the decrease in instrument efficiency can be further alleviated.
また、透光板４０の内面４０ｃを凸面にして、
黒板１０の全面が均一の明るさになるように配光
制御することにより、より一層黒板１０が見易く
なる。 Moreover, the inner surface 40c of the transparent plate 40 is made a convex surface,
By controlling the light distribution so that the entire surface of the blackboard 10 has uniform brightness, the blackboard 10 becomes easier to see.

According to the blackboard lamp of this invention, the diagonally downward illumination opening of the lamp body is covered with a transparent plate.
Chalk powder does not enter the lamp body, and is also difficult to adhere to the light-transmitting plate in an obliquely downward position, and even if it adheres, it can be easily removed, and the reduction in efficiency of the lamp can be alleviated. In addition, the transparent plate is installed by inserting its upper and lower edges into the mounting grooves of the lamp body, making it easy to attach and remove.Furthermore, the reflective plate is located closer to the front end of the lamp body than the lamp socket. This has the advantage that it can be easily attached and detached without being disturbed by the lamp socket, and that maintenance such as cleaning inside the lamp body and lamp replacement can be easily performed.
