Ignition device 17 comprises shown in Fig. 1 (a), Fig. 1 (b): circuit component 17a constitutes the lamp circuit of each LED11a; And circuit substrate 17b, circuit component is installed.Lamp circuit is to constitute as follows: convert alternating voltage 100V to about 24V DC voltage, each LED11a is supplied with the DC current of constant current (constant current).Circuit substrate 17b comprises the glass epoxide material that is criss-cross short strip shape, at single or double electronic component is installed, and make described circuit substrate 17b for vertical, the first half roughly is inserted in the cavity of retention tab 15b1 from the basal part 15a of holder 15, the latter half roughly is disposed in the housing recess 16c of union body 16 and is subjected to supporting (Fig. 2).Circuit substrate 17b also can utilize silicone resin or epoxy resin etc. to have the bonding agent of thermal conductivity, and is bonded in the inner surface of retention tab 15b1, union body 16.

Then, at the lead-out terminal connection electric wire w1 of circuit substrate 17b, described electric wire w1 inserts the slotting logical 15b2 of portion of electric wire of logical holder 15 and is connected with the connector 11c1 of substrate 11c.And, connecting input line (not shown) at the input terminal of circuit substrate 17b, described input line is connected in lamp holder member 14.Moreover ignition device 17 is built in the bulb preferably as mentioned above, constitute and directly to substitute the ordinary incandescent lamp bubble, but as compact (compact) type fluorescent lamp, ignition device also can be arranged at the utensil side that lamp is installed in addition, constitutes and is not built in the bulb side.

Thus, constitute the lamp 10 of the band lamp holder of bulb-shaped, the lamp 10 of described band lamp holder steeps similarly with ordinary incandescent lamp, front face side to side periphery from the top contains the covering member 13 of PS shape, described covering member 13 is formed with lampshade to increase light-emitting area, at another distolateral lamp holder member 14 that the E26 type is set, whole face shaping forms the face shaping roughly the same with the profile of ordinary incandescent lamp bubble integral body.

Secondly, the action of the lamp 10 of the band lamp holder that constitutes as mentioned above is described.When providing power supply to the lamp 10 of being with lamp holder via lamp holder member 14 it being lit a lamp, as shown in Figure 2, from foursquare planar illuminating part radiating light of being of light source portion 11.The light A that radiates radiates and sees through to the inner surface of the upside covering 13a of portion, mainly the front face side at top is shone.And the light B of a part towards the reflection of back side direction, and sees through the downside covering 13b of portion by the light diffusing agent of the upside covering 13a of portion and from the side, with light from the side of bulb around going into to the mode of rear side to radiate.At this moment, in radiator 12, be formed with four roomy spatial portion S, the top of described four spatial portion S and outer side are opening, therefore by described spatial portion S, light B from light source portion 11 radiation can be blocked by the thinner radiator 12 of width hardly, and with respect to the side of bulb and the roughly full week of rear side, (in the roughly whole luminous mode of side and rear side) sees through roughly equably.

And, the content of covering member 13 by making the light diffusing agent among the upside covering 13a of portion is more than the content of the light diffusing agent of the downside covering 13b of portion, and the light transmittance that constitutes the upside covering 13a of portion is lower than the light transmittance of the downside covering 13b of portion, therefore become many by the light diffusing agent of the upside covering 13a of portion at the light B of inner surface reflection, on the contrary, the light A that sees through the upside covering 13a of portion reduces.

And, see through the downside covering 13b of portion of high transmission rate at the many light B of the change of inner surface reflection, with light from the side of bulb around going into to the mode of rear side to radiate.Thus, the effect that produces in conjunction with four roomy spatial portion S, namely, light B is roughly seen through to side and the rear side of bulb equably, the roughly radiation equably of whole face that can spread all over covering member 13 from the light of bulb radiation, the whole face of bulb is roughly luminous and can increase light-emitting area equably, thereby can obtain the roughly same light distribution characteristic approximate with the ordinary incandescent lamp bubble.

Simultaneously, after the lamp 10 that makes the band lamp holder was lit a lamp, the temperature of LED11a rose and produces heat.The wiring substrate 11b1 of the self-contained aluminium of described heat is passed to the substrate 11c that similarly contains aluminium, is passed to the radiating fin 12b1 of the radiator that contains aluminium 12 that is bonded with substrate 11c then.The extraneous air that is passed to the heat of radiating fin 12b1 and circulates in blank part 12b2 carries out heat exchange and to the outside heat radiation, described blank part 12b2 forms by radiating fin 12b1.

At this moment, blank part 12b2 comprises two blank parts that are communicated with radiation direction quadrature, an end face 12b3 of extraneous air self-forming blank part imports, and contact to the big plate face of area of the radiating fin 12b1 of heating and carry out heat exchange, emit (arrow A among Fig. 3) through the air of heat exchange to the outside from other end 12b3.Described heat exchange action is carried out simultaneously and is effectively dispelled the heat at two blank part 12b2 of quadrature.Particularly near the central part the nearer and hot optical axis that is easy to accumulate of light source portion because two blank part 12b2 of quadrature intersect, can carry out heat exchange by the extraneous air that imports from two blank part 12b2, so can carry out more effective heat radiation.And near the central part optical axis is formed with the broad space that section assumes diamond in shape, thereby can carry out more effective heat exchange.

In addition, owing to the end face 12b3 of the radiating fin 12b1 that exposes from covering member 13 is mutually continuous and integrated with the outer peripheral face of covering member 13, as a whole, outward appearance constitutes the shape of the contour approximation of the neck shape portion of steeping with ordinary incandescent lamp, therefore as among Fig. 3 with shown in the arrow B, extraneous air can be directed and be sucked into blank part 12b2 along the inclination of the bending of neck shape portion, therefore more extraneous air can be directed into blank part, and carry out more effective heat radiation.By these effective thermolysis, the temperature of LED11a rises and is inhibited.This is the stack effect (chimney effect) that utilizes the long blank part 12b2 of the little and depth of width to produce, extraneous air is continuously sucked from an end face 12b3, and continuously emit from other end 12b3, thereby can in the process of lighting a lamp, carry out heat exchange constantly and the heat radiation that continues always.

And, the retention tab 15b1 of holder 15 that is inserted with the circuit substrate 17b of ignition device 17 simultaneously be positioned at blank part 12b2 roughly in the middle of height, so make retention tab 15b1 obtain cooling by the extraneous air that is sucked into blank part, built-in circuit substrate 17b also obtains cooling, so also can suppress the temperature rising of circuit component 17a, thereby also can improve the reliability of electronic component.

Secondly, the formation of ligthing paraphernalia be described, described ligthing paraphernalia be with as mentioned above and the lamp 10 of the band lamp holder of the bulb-shaped of formation as light source.Shown in Fig. 4 (a), the 20th, the existing light fixture of Down lamp formula is embedded in the ceiling surface X in shop etc. and arranges, and is light source with the ordinary incandescent lamp bubble of the lamp holder that comprises the E26 type, comprise: the metal apparatus body 21 that is the case shape comprises peristome 21a at lower surface; Metal reflector 22 is embedded in peristome 21a; And lamp socket 23, can be screwed into the lamp holder of the E26 type of ordinary incandescent lamp bubble.Reflector 22 comprises for example metallic plate of stainless steel etc., at the central portion of the upper surface panel of reflector 22 lamp socket 23 is set.

In the existing light fixture 20 of the ordinary incandescent lamp bubble usefulness that constitutes as mentioned above, for energy-conservation or long lifetime etc., installing above-mentioned is that the lamp 10 of band lamp holder of the bulb-shaped of light source substitutes ordinary incandescent lamp and steeps with LED.That is, the lamp of the band lamp holder of bulb-shaped is that lamp holder member 14 is constituted the E26 type, so can directly be inserted into the lamp socket 23 of the ordinary incandescent lamp bubble usefulness of described ligthing paraphernalia 20.

And, the outward appearance of the lamp 10 of band lamp holder constitutes the shape of the contour approximation of the neck shape portion of steeping with ordinary incandescent lamp, therefore neck shape portion can not touch reflector 22 grades of lamp socket periphery and insert smoothly, thereby the relevance factor of 10 pairs of existing ligthing paraphernalias of lamp of the band lamp holder of bulb-shaped improves.Thus, existing Down lamp can be become simply following energy-saving Down lamp, that is, described energy-saving Down lamp is provided with LED the lamp 10 of band lamp holder of the bulb-shaped that is light source.Certainly, not only have utensil now, the new ligthing paraphernalia that constitutes also can similarly constitute.

Secondly, the action of Down lamp 20 be described, described Down lamp 20 be with as mentioned above and the lamp 10 of the band lamp holder of formation as light source.When with power connection during to the Down lamp that constitutes as mentioned above, the lamp 10 from lamp socket 23 to the band lamp holder provides source power supply via lamp holder member 14, and ignition device 17 carries out work and exports the DC voltage of 24V.Described DC voltage is to be applied to each LED11a from ignition device 17, supplies with the DC current of constant current, and all LED light a lamp simultaneously and radiate white light.

From the white light of each LED11a radiation as mentioned above, spread all over whole of covering member 13 and roughly radiation equably, light, can not reduce from side to the rear side light quantity of bulb around going into to rear side from the side of bulb.This can increase light-emitting area and obtain the roughly same light distribution characteristic approximate with ordinary incandescent lamp bubble, so near the exposure of the light of the reflector 22 lamp socket 23 increases, described lamp socket 23 is to be disposed in the ligthing paraphernalia 20, can obtain as the utensil characteristic as the optical design of reflector 22, described reflector 22 is to constitute as ordinary incandescent lamp bubble purposes, thereby can have the roughly illumination of same light distribution characteristic approximate with the ordinary incandescent lamp bubble.

Simultaneously, after the lamp 10 of the band lamp holder of bulb-shaped is lit a lamp, the temperature of LED11a rises and produces heat, yet can be as mentioned above radiating fin 12b1 by radiator 12 and blank part 12b2 and heat radiation effectively, can suppress the decline of the luminous efficiency of LED, brightness can not descended, and the reliability of electronic component also gets a promotion in addition, thereby long-life ligthing paraphernalia can be provided.

And ligthing paraphernalia is not limited to Down lamp, shown in Fig. 4 (b), also can be made as the bracket-shaped ligthing paraphernalia of formation, and it is arranged on the wall X.Described carriage 20 comprises the Transparent lamp shade 24 that makes the top open, and the lamp 10 of the band lamp holder of present embodiment is arranged towards the top by lamp socket 23.Thus, carrying the light of the lamp 10 of lamp holder can be towards the top, side and below radiation and shine wall etc. equably.And in the lamp 10 of band lamp holder, light, can not reduce from side to the rear side light quantity of bulb around going into to rear side from the side of bulb, so the bracket-shaped ligthing paraphernalia that can provide a kind of brightness that can effectively utilize horizontal direction especially to throw light on.

More than, according to present embodiment, can provide a kind of lamp with lamp holder and ligthing paraphernalia, can improve the heat dispersion of LED, and close with the light distribution characteristic of conventional lighting sources such as ordinary incandescent lamp bubble, can bring into play following action effect simultaneously.

According to present embodiment, covering member 13 is divided into two and constitutes in maximum diameter portion, so it is bigger that the diameter dimension of radiator 12 is configured, till maximum diameter portion roughly, thereby can enlarge the area of radiating fin 12b1, can carry out more effective heat radiation.Moreover covering member 13 can not be divided into two in maximum diameter portion yet, and along optical axis x-x towards vertically being divided into two.At this moment, also can enlarge the diameter of radiator 12, till the roughly maximum diameter portion of covering member 13.And, according to described formation, not only can enlarge the area of radiating fin 12b1, and the size of light source portion 11 also can be configured bigger, thereby also can constitute the lamp of the band lamp holder of higher output.

In addition, radiator 12 is to utilize the sheet material of aluminium to constitute blank part 12b2 and effectively dispel the heat, so can make the weight saving of bulb.Particularly in the present embodiment, do not use the body housing that comprises the thicker aluminium of wooden partition etc., just can carry out the heat radiation of LED, therefore weight is further alleviated, and be conducive to reduce cost yet.And, covering member 13 is formed with opening portion 13b3, be used for making radiating fin 12b1 to expose, also extraneous air can be put into to covering member 13, thereby the temperature that also can suppress covering member 13 rises, even the time standby hand in the back of just turning off the light etc. touches bulb and does not also scald, thereby also can easily operate bulb.This also can emit the heat of covering member 13 by radiating fin 12b1 when the bonding agent that utilizes good silicone resin of thermal conductivity etc. is bonding in addition with the end face 12b3 of opening portion 13b3 and radiating fin 12b1.
