Example Embodiment

[0016] Example 1
[0017] A side-removable bulb projector of the present invention includes a bulb cover 1, a cover screw 2, a bulb component 3, a handle 4, a component fixing screw 5, a bulb power socket 6, a projector 7, and the side of the projector 7 has The side opening 8 is equipped with a light bulb power socket 6; there is a side opening 8 inside the bulb assembly 3, which can be inserted or pulled out; the bulb assembly 3 and the projector 7 are connected with the assembly fixing screw 5, the bulb assembly 3 There are heat dissipation holes 9, positioning posts 13, power plugs and handles 4; there is a bulb in the bulb assembly 3. After the bulb assembly 3 is inserted into the side opening 8, the power plug is simultaneously inserted into the bulb power socket 6; there is a bulb on the side opening 8 Cover 1, the lamp cover 1 has a buckle 10, the buckle 10 clamps the lamp cover 1 on the projector and fixes it with the cover screw 2.

Example Embodiment

[0018] Example 2
[0019] According to a side-removable bulb projector described in embodiment 1, a safety switch 11 is provided on the projector 7, and a safety switch lever 12 is provided on the bulb cover 1. The switch is turned on when the bulb assembly 3 is inserted, and the projection The projector can work normally. When the lamp assembly 3 is pulled out, the switch is disconnected, and all the power in the projector is cut off to prevent electric shock accidents.

Example Embodiment

[0020] Example 3
[0021] Attached image 3 It is a schematic structural diagram of Embodiment 3 of the present invention. According to the above-mentioned side-removable lamp projector, the projector 7 and the lamp cover 1 are connected by a hinge 14; this can prevent the lamp cover from being dropped or lost after being removed problem.
[0022] To sum up, the lamp opening of the present invention is placed on the side of the projector, maintenance personnel can stand on the side to perform disassembly and assembly operations, conveniently realize the maintenance of the lamp assembly and lamp replacement, and avoid the hazards of lamp debris and foreign objects. Maintenance personnel.
