Abstract
The utility model discloses a blackboard illuminating lamp, which is mounted on a side frame of the upper edge of the blackboard, the outside of a lamp hood is connected with a fixing rack, the upper part in the lamp hood is provided with a circuit board, the lower part thereof is provided with a transparent plate, the circuit board is placed on a lug boss, the transparent plate is inserted in a slot, an M-shaped focusing groove is mounted between the circuit board and the transparent plate, the circuit board is provided with two parallel rows of LED lamps, and two ends of the lamp hood are mounted with side covers. The blackboard illuminating lamp is mounted on a side frame of the upper edge of the blackboard, which is divided into a plurality of sections. When in use, each section can move up and down by rotating shafts, thereby the installation and the maintenance are very convenient. The blackboard illuminating lamp has the advantages of centralized illuminating beams, high utilization rate, safety and energy saving, and small volume, and can move with the blackboard.
Description
Technical field
The utility model relates to the lighting apparatus in a kind of teaching, refers in particular to the blackboard illuminating lamp.
Technical background
Because blackboard and multimedia be in teaching and with can improving the quality of teaching to a great extent, so no matter teaching unit now is colleges and universities or middle and primary schools, the utilization rate that nanometer blackboard and multimedia are combined is more and more higher.
Multimedia teaching requires the classroom darker.Because a little less than the nanometer blackboard reflective light, desire to see clearly the brightness that writing on the blackboard is just had relatively high expectations, both environments for use have just produced conflict like this, cause both being used in combination to be subjected to certain restriction.Open blackboard lights during with blackboard, the time spent is not turned off blackboard lights, certainly solves this contradiction, but very big weak point is arranged like this:
1, troublesome poeration because the switch of blackboard lights is far away from Faculty and Students, last class hour at any time the switch blackboard lights just produced a lot of inconvenience, influence teaching efficiency.
2, waste energy, now the blackboard lights that uses of classroom all is a fluorescent lamp, because fluorescent start can consume much electricity, frequent switch blackboard lights has increased blackboard lights to the consumption of the energy and shortened service life of lamp.
3, in school now, especially in the colleges and universities, do not teach though recurrent thing is the teacher, the blackboard lights in the classroom is still being opened in the same old way, has so also wasted power supply.
The utility model content
The technical problems to be solved in the utility model provides a kind of blackboard illuminating lamp, and this blackboard illuminating lamp is installed on the blackboard frame, not only can well solve the disadvantage that existing teaching illuminating lamp uses, but also very attractive in appearance, energy-conservation.
Problem to be solved in the utility model is realized by following scheme: the blackboard illuminating lamp, be installed on the frame of blackboard upper edge and form by more piece, comprise LED lamp, lampshade, circuit board, it is characterized in that: the described lampshade outside is connected with fixed mount, and the top is provided with circuit board in the lampshade; The below is provided with light-passing board, circuit board is shelved on the lampshade inner convex platform, and light-passing board is inserted in the slot, and M shape condenser groove is housed between circuit board and the light-passing board, the parallel two row LED lamps that are equipped with of described circuit board, side cover is installed in the described outside that is positioned at more piece blackboard illuminating lamp both ends.
The utility model also comprises following scheme: described fixed mount top is provided with the perforation that is connected with the frame of blackboard upper edge.Described M shape condenser groove top is provided with the two row LED lamp corresponding matching of installing on two row holes and the described circuit board.
The utility model has the advantages that: this blackboard illuminating lamp is installed on the frame of blackboard upper edge, is divided into more piece, and the structure of every joint all as mentioned above.During use, every joint can rotate up and down by turning cylinder, and installation, maintenance is very convenient.This blackboard illuminating lamp light is concentrated, utilization rate is high, energy-saving safe, and volume is little, can move with blackboard.

The specific embodiment
As Fig. 1-shown in Figure 4, this blackboard illuminating lamp is installed on the frame of blackboard upper edge, totally 10 joints (2 joints only draw among Fig. 1), and side cover 1 is installed in the outsides that are positioned at 10 joint blackboard illuminating lamp both ends.10 joint blackboard illuminating lamps can illuminate the long whole blackboard of 5m.Every joint lamp can rotate up and down by turning cylinder.Lampshade 2 outsides are connected with triangle fixed mount 3, and triangle fixed mount 3 tops are provided with the perforation 4 that is connected with the frame of blackboard upper edge.The top is provided with circuit board 5 in the lampshade 2; The below is provided with light-passing board 6, and circuit board 5 is shelved on the boss 7, and light-passing board 6 is inserted in the slot 8, and M shape condenser groove 9 is housed between circuit board 5 and the light-passing board 6, the circuit board 5 parallel two row LED lamps 10 that are equipped with.M shape condenser groove 9 tops are provided with two row LED lamps, 10 corresponding matching of installing on two row holes 11 and the circuit board 5.As shown in Figure 7, most of light is fallen the higher middle hypomere of blackboard utilization rate, and the blackboard epimere is because nearer from light source, thus also brighter, so not only guarantee the brightness and the bright uniformity of full blackboard, and do not lost light.This blackboard illuminating lamp to the utilization rate of light source more than 90%.
As Fig. 5, shown in Figure 6, every joint blackboard illuminating lamp is formed (other arranges 4 for two row LED lamps, 5 of rows) by 9 LED lamps 10, and length is 50cm.The 10cm of being separated by between per two lamps among the same row apart from 4cm, can make full use of all light that each LED lamp 10 sends between two bank lights like this.
Claims (3)
