Embodiment

The utility model is described in detail with reference to specific embodiment.Following examples will be helpful to this area Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that to ability For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made. These belong to the scope of protection of the utility model.

As shown in Figure 1 to Figure 3, bulb lamp provided by the utility model includes lamp body, luminescent device 2 and luminous intensity distribution part, its Middle lamp body includes power supply installed part and radiating piece；Power supply installed part, radiating piece, luminous intensity distribution part are sequentially connected；Power supply installed part then wraps Containing power supply 41, power source cavity 42, power supply chamber lid 43 and lamp holder 44；Radiating piece includes ceramic heat-dissipating body 31 and radiating body support frame 32. Luminescent device 2 is then arranged on ceramic heat-dissipating body 31, and evenly distributed in the circumferential direction.

The luminous intensity distribution part of bulb lamp provided by the utility model includes diffuser 11 and catoptric arrangement, what luminescent device 2 was sent The light of the central area of directive diffuser 11 includes a part of light and another part light, wherein, a part of light quilt The catoptric arrangement reflexes to diffuser outer peripheral areas, and another part light reaches diffuser 11 through the catoptric arrangement Central area, central area are surrounded by outer peripheral areas, such as shown in Fig. 3, region shown in I is central area, and region is shown in II Outer peripheral areas.In embodiment, catoptric arrangement includes the reflector 12 as described in Fig. 4, Fig. 5, between reflector 12 and diffuser 11 It is detachably connected, reflector 12 includes flared structure, and the opening of flared structure is backwards to lamp body；Outside the arc of flared structure Side forms reflecting surface；A part of light that reflecting surface sends luminescent device 2 reflexes to diffuser outer peripheral areas；The printing opacity Cover 11 includes revolving shell, and reflector 12 is arranged on inside the revolving shell.It is provided with the flared structure of reflector 12 logical Hole, in embodiment, the through hole is to turn round the first through hole that contour direction extended along flared structure, and multiple institutes be present Stating first through hole, circumferentially direction is uniformly arranged.Reflector 12 with through hole is set, on the one hand can allow what luminescent device 2 was sent Another part light can irradiate space corresponding to the central area of diffuser 11, on the other hand can also provide extra radiating way Footpath, the temperature of bulb lamp is reduced, in the prior art, the heat that LED chip is sent again will through air transmitted to diffuser, diffuser Heat is transmitted to outside air and radiated, and in the utility model, a part for the heat that LED chip is sent directly passes through reflection Device 12 is transmitted to diffuser, and a part of heat is then directly delivered to air by convection type.Preferably, reflector 12 is high anti- Plastics, in light weight, reflection efficiency is high, in addition, reflector 12 can also be made of metal, but in terms of insulation, and with pottery Assembling heat transfer between porcelain radiator 31, effect is all not as good as high anti-plastics.It is, of course, preferable in example, above-mentioned through hole can also be edge The second through hole that the circumferential direction of flared structure is extended, such as each second through hole extend 45 along the circumferential direction Spend, 4 the second through holes are uniformly distributed on same circumference, and contour direction is turned round along flared structure, there may be multiple The circumference of the second through hole is distributed with；It is further preferred that can also exist simultaneously on flared structure above-mentioned first through hole with Second through hole.Furthermore it is preferred that in example, for first through hole, the big end end up to flared structure is may be extended to, or even wear The big end end for crossing flared structure forms fluting, and reflector 12 is separated into more valves by a kind of situation, and in flared structure Small end is connected with each other；Another situation is then to form through hole in the junction of reflector 12 and diffuser 11.In embodiment, to increase The radiating effect on the surface of strong reflection device 12, is additionally provided with rib on flared structure, and rib is located at the inner side of flared structure On face, its bearing of trend can be the revolution contour direction or circumferentially direction, or above-mentioned two along flared structure The rib of kind bearing of trend has setting.

In change case, catoptric arrangement can not also be reflector 12, but have extension, extension on diffuser 11 On be provided with reflecting layer, such as silver, the metal material layer of chromium are coated with reflecting layer, or posts reflective sheeting, so as to form reflection Luminescent device 2 is sent a part of light and reflexes to diffuser outer peripheral areas by structure, reflecting layer.Preferably, on diffuser 11 Extension also has flared structure, and arc external side of the reflecting layer along flared structure is set, and on flared structure Through hole and rib setting form and reflector 12 it is same or similar, difference is, first through hole extends through tubaeform knot Behind the big end end face of structure, first through hole is still located on diffuser 11.

Not installing the test result of catoptric arrangement, distribution curve flux, the test result for being provided with catoptric arrangement are shown in as shown in Figure 6 Distribution curve flux shown in Fig. 7, it is seen that：The bulb lamp for being provided with catoptric arrangement significantly increases on lighting angle, and light intensity point Cloth is more uniform.

Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, This has no effect on substantive content of the present utility model.
