The adjustable for height shot-light of a kind of bulb socket inner chamber
The utility model relates to a kind of light fixture, especially a kind of shot-light.
Present prior art, traditional P AR38 shot-light comprises bulb socket, LED driving power, radiating shell, LED lamp group, lens subassembly. there is installing hole at the center of said radiator, and a brace table is arranged in the installing hole, and the wiring board of LED lamp group cooperates with brace table; Lens are attached on the lamp pearl, and lens carrier and radiating shell pass through screw. and bulb socket is fixed on the radiating shell through screw.LED driving power input wires is connected with bulb socket; The wiring board welding of the other end and LED illuminator.Existing problems are: the LED driving power contacts with radiating shell, has potential safety hazard.Whole assembling is inconvenient, and work efficiency is low.
Summary of the invention.
The purpose of the utility model is: provide a kind of bulb socket inner chamber adjustable for height shot-light; It not only can be fit to the LED power supply of different size; And make the LED driving power isolate fully with radiator casing and insulate. prevent to contact electric leakage, eliminated potential safety hazard.
The utility model is achieved in that the adjustable for height shot-light of a kind of bulb socket inner chamber; Comprise bulb socket, LED driving power, finned radiator, LED lamp group and lens subassembly; There is installing hole at the center of said finned radiator; One brace table is arranged, ring platform in having in the installing hole on brace table top in the installing hole; The pcb board lower surface of LED lamp group and brace table are fitted; The pcb board upper surface of LED lamp group cooperates with the bottom of the lens retainer plate of lens subassembly; The hole that the lamp pearl of LED lamp group passes the bottom of lens retainer plate is positioned at the lens retainer plate, and screw passes the pcb board of brace table and LED lamp group from the brace table back side and the lens retainer plate of lens subassembly screws togather; The LED driving power is fixed in the convex cutting ferrule of bulb socket; It is characterized in that: also comprise lamp holder lid, the upper shed that said lamp holder lid covers the convex cutting ferrule of bulb socket.
The shot-light of described a kind of bulb socket adjustment height, its special character is: also comprise a lamp sleeve, lamp sleeve has upper and lower opening;
The upper shed of the convex cutting ferrule of the lower end of lamp sleeve and bulb socket removably connects, the upper shed that the lamp holder lid covers lamp sleeve.
The adjustable for height shot-light of a kind of bulb socket inner chamber of the utility model owing to adopt this spline structure, can be fit to the LED power supply of different size, and LED driving power and radiator are isolated in being provided with of lamp holder lid, have prevented electric leakage, have eliminated potential safety hazard; And the insulation of lamp holder lid, integral body can not influence the heat radiation of LED driving power.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in Figure 2; The adjustable for height shot-light of a kind of bulb socket inner chamber; Comprise bulb socket 1, LED driving power 2, finned radiator 3, LED lamp group 4, lens subassembly 5; There is installing hole 31 at the center of said finned radiator 3, have in the installing hole 31 have in the installing hole 31 on a brace table 32, brace table 32 tops in ring platform 33; Fit in pcb board 41 upper surfaces of LED lamp group 4 and lens retainer plate 51 bottoms in the lens subassembly 5; The hole that the lamp pearl 42 of LED lamp group 4 passes the bottom of lens retainer plate 5 is positioned at lens retainer plate 51, and screw passes the pcb board 41 of brace table 32 and LED lamp group 4 from brace table 32 back sides and the lens retainer plate 51 of lens subassembly 5 screws togather; Lens 52 removably connect with lens retainer plate 51; LED driving power 2 is arranged in the convex cutting ferrule 11 on the bulb socket 1;
Also comprise lamp holder lid 6, said lamp holder lid 6 covers the upper shed of convex cutting ferrule 11 and removably connects with upper shed, and the block tongue 61 on the lamp holder lid 6 cooperates with the hole clipping on the convex cutting ferrule 11.Convex cutting ferrule 11 inserts in the installing hole 31 of finned radiator 3, and screw passes bulb socket 1 and screws togather with finned radiator 3; The support tube 12 of bulb socket 1 is pegged graft with the interface of the bottom of finned radiator 3 34, and the end of support tube 12 and finned radiator 3 are fitted.
As further improvement: also comprise a lamp sleeve 7, lamp sleeve 7 has upper and lower opening;
The upper shed of the lower end of lamp sleeve 7 and convex cutting ferrule 11 removably connects, the upper shed that lamp holder lid 6 covers lamp sleeve 7.Lamp sleeve 7 is positioned at the installing hole 31 of finned radiator 3;
Lamp holder lid 6 week block tongue 61 is arranged upwards, hole clipping 71 is arranged on the lamp sleeve 7, block tongue 61 cooperates with hole clipping 71.
Adopt such structure, can be as requiredThe size of LED driving power 2 profiles increases or cancellation lamp sleeve 7.
Above-described only is the preferential embodiment of the utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is regarded as the protection domain of the utility model.
