Fig. 9 shows a schematic front view of the projector after the bead 6 in the standby light outlet 42 is removed.

Fig. 10 shows a front schematic view of the projector, in which the lamp beads 6 in the spare light outlet 42 are detached and the light-transmitting plate 5 is provided with a covering area 51.

Alternatively, a light-tight patch may be attached to the outer surface of the covering area 51 on the light-transmitting panel 5, so that during the actual assembly process, when it is not necessary to install the lamp beads 6 in the spare light-emitting opening 42, the patch is attached to the covering area 51 on the light-transmitting panel 5, so that the spare light-emitting opening 42 is covered.

Further alternatively, an opaque oil seal may be attached to the outer surface of the covering area 51 on the light-transmitting plate 5, so that during the actual assembly process, when it is not necessary to install the lamp bead 6 in the spare light-emitting opening 42, the covering area 51 on the light-transmitting plate is covered by the oil seal, so that the spare light-emitting opening 42 is covered.

For example, a painted or frosted layer may be provided on the outer surface of the covering area 51 on the light-transmitting plate 5, and the spare light outlet 42 may be covered by assembling different light-transmitting plates 5.

In some examples, referring to fig. 1, fig. 2, fig. 8 and fig. 10, it can be understood that one or more alignment blank clear areas 52 are disposed on the covering area 51, one or more alignment marks 43 are disposed on the lamp cover 4, the alignment marks 43 correspond to the alignment blank clear areas 52 one to one, and whether the alignment marks 43 are aligned with the alignment blank clear areas 52 is conveniently determined by observing the alignment blank clear areas 52, so that the light-transmitting plate 5 and the lamp cover 4 are quickly aligned, and therefore, the assembly efficiency between the light-transmitting plate 5 and the lamp cover 4 is improved, and the assembly accuracy between the light-transmitting plate 5 and the lamp cover 4 is also improved. Meanwhile, the accuracy of covering the standby light exit 42 by the covering region 51 is improved.

Optionally, with reference to fig. 1, fig. 2 and fig. 6, it can be understood that lenses 44 are disposed in the assembly light outlet 41 and the standby light outlet 42, and the illumination emitted by the lamp beads 6 can be uniformly distributed through the lenses 44, so that the projector emits a uniform illumination effect.

In detail, as shown in fig. 1, 4 and 5, the projector of the present embodiment further includes a mounting plate 7 and a rear cover 8, the mounting plate 7 is disposed on the rear portion of the lamp body 1, the rear cover 8 is connected to the rear portion of the lamp body 1, a receiving cavity for receiving the power supply 3 is formed between the rear cover 8 and the mounting plate 7, and the power supply 3 is disposed on the mounting plate 7. Further protection is carried out to power 3 through 8 cooperation mounting panels 7 in the back, avoids appearing the impaired problem of power 3.

In some embodiments, as shown in fig. 3, 4 and 5, the mounting plate 7 is provided with a wire-passing sheath 9, the wire-passing sheath 9 is provided with at least one first wire-passing hole 91, and the rear cover 8 is provided with an avoiding notch 81 for avoiding the wire-passing sheath 9. In actual assembling process, can cross the first line hole 91 of crossing on the line sheath 9 with power 3's wire earlier, then will cross line sheath 9 and be connected with mounting panel 7 again, be connected back lid 8 and the rear portion of lamp body 1 afterwards, traditional projecting lamp generally will cross the line hole and directly set up on back lid 8, the loading and unloading of back lid 8 of being not convenient for, and this application is dodged breach 81 cooperation through setting up at back lid 8 and is crossed line sheath 9 and assemble, so that the loading and unloading of back lid 8, make the projecting lamp loading and unloading more laborsaving, and cross line hole 91 through crossing on the line sheath 9 first and further fix power 3's wire, make power 3's wire fixed more firm.

For example, as can be understood by referring to fig. 3 and fig. 4, a positioning point 92 is disposed on one side wall of the wire passing sheath 9, a clamping hole corresponding to the positioning point 92 is disposed on the mounting plate 7, and a clamping groove 93 is disposed on another upper side wall of the wire passing sheath 9, in an actual assembly process, the positioning point 92 is clamped in the clamping hole, so that the wire passing sheath 9 is fixed on the mounting plate 7, and the inner side wall of the avoiding notch 81 is clamped in the clamping groove 93, so that the wire passing sheath 9 is connected with the rear cover 8 more stably.

Specifically, as shown in fig. 3 and 4, at least one second wire passing hole 11 is provided on the lamp body 1, and the second wire passing hole 11 is communicated with the mounting recess. The arrangement is such that the conducting wires on the substrate 2 are led out from the second wire through hole 11 and electrically connected with the conducting wires on the power supply 3.

In some examples, a convection groove 12 vertically penetrates through the middle part of the lamp body 1, and the power supply 3 is separated from the substrate 2 through the convection groove 12, so that heat emitted by the lamp beads 6 on the substrate 2 is prevented from being easily transferred to the power supply 3, and the service life of the power supply 3 is prolonged; wherein, interval distribution has a plurality of heat dissipation muscle 13 in the convection current groove 12, increases the area of contact to the chute 12 and air through heat dissipation muscle 13, and the heat that makes lamp pearl 6 send gives off speed faster, improves the life of lamp pearl 6, and the support effect through heat dissipation muscle 13 improves the anti deformability of lamp body 1 simultaneously.

As shown in fig. 4, in a practical production embodiment, the second wire hole 11 is disposed on the sidewall of the convection slot 12, so as to shorten the distance between the first wire hole 91 and the second wire hole 11, thereby shortening the wires electrically connected between the power source 3 and the substrate 2, and further saving the production cost of the projector.

In some examples, as shown in fig. 1 and 6, a rotatable mounting bracket 10 is connected to the lamp body 1, so that the lamp body 1 can be lifted by the mounting bracket 10, thereby improving the overall convenience of use. Meanwhile, the projection angle of the projector lamp can be adjusted by rotating the mounting bracket 10.

Alternatively, through holes are respectively formed at both sides of the mounting bracket 10, and both sides of the mounting bracket 10 are rotatably connected to both sides of the lamp body 1 by rotating pins penetrating through the through holes.

Synthesize above-mentioned, through set up reserve light-emitting window 42 on lamp lid 4, be convenient for install lamp pearl 6 and assemble into the projecting lamp of different illumination scopes on base plate 2, the equipment is nimble. When a projection lamp with a large illumination range needs to be produced, the lamp bead 6 can be installed in the standby light outlet 42, and the lamp bead 6 is electrically connected with the substrate 2; when the projecting lamp that the illumination scope is less is produced to needs, do not join in marriage lamp pearl 6 in the reserve light-emitting window 42, reduced the use quantity of lamp pearl 6, improved the price/performance ratio of projecting lamp. Meanwhile, under the condition that the standby hole is vacant, the covering area 51 is arranged on the light-transmitting plate 5, and the standby light outlet 42 is prevented from influencing the overall attractiveness of the projection lamp.

It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
