技术领域 FIELD

本发明是有关于将例如发光二极管(light-emitting diode)般的半导体元件用作光源的灯,特别是有关于在灯点灯时可将光源发出的热高效率地散发到灯外部的灯。 The present invention relates to a lamp element such as a semiconductor light-emitting diode (light-emitting diode) as a light source like, particularly to a high thermal efficiency at the time of lighting the lamp can be dissipated to the outside of the light source lamp lights.

背景技术 Background technique

作为可替代白炽灯的灯用光源,已知有发光二极管。 As an alternative incandescent lamp light source, there is known a light emitting diode. 发光二极管伴随其温度上升时,其光输出将会下降并且寿命亦将变短。 When the temperature rise accompanied by a light emitting diode, the light output will also be lowered and the lifetime is shortened. 故而,以发光二极管作为光源的灯必须能够抑制发光二极管的温度上升。 Therefore, a light emitting diode lamp as a light source must be able to suppress the temperature rise of the light emitting diode.

例如,在曰本专利特开2001 - 243809号公报中揭示有LED电灯,此LED 电灯通过提高发光二极管的散热性而防止发光二极管过热。 For example, in said Patent Laid-Open present 2001-- Publication No. 243,809 discloses an LED lamp, the LED lamp by improving the heat dissipation of the light emitting diode and a light emitting diode to prevent overheating. 先前的LED电灯包括灯体、金属基板以及多个发光二极管。 Previous LED lamp comprising a lamp body, a metal substrate, and a plurality of light emitting diodes. 灯体由以下构成:在一端具有灯座(base)并且在另一端设置具有开口的金属制散热部,并且在金属制散热部另一端设置有透明罩。 Lamp body constituted by: a socket (base) and a heat radiating portion provided at the other end of the cover is provided with a transparent portion having a metal radiator opening, and at the other end made of metal at one end. 金属制散热部是从一端朝向另一端呈喇叭状扩展的形状。 Metal radiator other end portion is flared shape extended from one end. ' '

金属基板通过具有电绝缘性的高热传导构件,而固定在金属制散热部的开口。 A metal substrate having a high heat conductive member is electrically insulating, the heat dissipation portion fixed to an opening made in metal. 发光二极管由金属基板支撑并且被透明罩覆盖。 And a light emitting diode is covered by a transparent cover supported by a metal substrate.

在LED电灯进行照明时,发光二极管所发出的热从金属基板通过高热传导构件而传递到金属制散热部。 When the LED lighting lamp, the light emitting diode of heat transmitted from the metal substrate by a conductive member to heat the metal radiator portion. 传递到金属制散热部的热,会从金属制散热部的外周面散发至大气中。 Transferred to the heat radiating portion of the metal, the metal will be radiated from the outer peripheral portion of the surface of the heat to the atmosphere. 由此,可抑制发光二极管过热,且可提高LED电灯的发光效率(luminous efficacy )。 Accordingly, overheating of the light emitting diode can be suppressed, and can improve the light emission efficiency of the LED lamp (luminous efficacy).

根据日本公开专利公报所揭示的LED电灯,散发发光二极管所发出的热的金属制散热部与安装有发光二极管的金属基板为不同的构成要素。 Metal radiator portion of the metal substrate according to the LED lamp disclosed in Japanese Laid-Open Patent Publication, distribution of heat emitted from the light emitting diode is mounted with light emitting diodes of different components. 如此结构中,金属基板与金属制散热部通过高热传导构件而结合在一起,但是无法避免在金属基板与金属制散热部的结合部分产生热阻(thermal resistance)。 In such a structure, the metal substrate and the metal heat radiating portion are bonded together by high thermal conduction member, but can not avoid thermal resistance (thermal resistance) on the metal substrate and the metal binding portion of the radiating portion. 因此,会影响在金属基板与金属制散热部之间进行的热传导,且无法将发光二极管的热高效率地从金属基板传递到金属制散热部。 Thus, the metal can affect the thermal conductivity between the substrate and the metal be made of the heat radiating portion, and light emitting diodes can not be highly efficient heat transfer from the metal substrate to metal radiator portion. 因此, 在抑制发光二极管的温度上升方面尚待进一步改善。 Thus, yet further improved to suppress the temperature rise of the light emitting diode aspects.

进而,上述LED电灯中使发光二极管点灯的点灯电路为必要构成要素。 Furthermore, manipulation of the LED lamp lighting circuit for lighting the light emitting diode as an essential constituent element. 当将点灯电路装入LED电灯时,必须做到不会因为存在有点灯电路而导致LED电灯变大。 When the LED lamp lighting circuit load, because there must be done without resulting LED lamp lighting circuit becomes large. 同时众所周知,如果点灯电路平时温度过高,则电路动作的可靠性将会下降,并且寿命将会受到损害。 Meanwhile it is well known, if the temperature is too high normal lighting circuit, the reliability of the circuit operation will be reduced, and the lifetime will suffer. 故而,当将点灯电路装入LED 电灯时,不可或缺的是抑制点灯电路过热。 Therefore, when the charged LED lamp lighting circuit, the lighting circuit is indispensable to suppress overheating. 然而,在上述日本的公开专利公报中没有关于点灯电路的揭示。 However, no disclosure in the above regarding lighting circuit disclosed in Japanese Patent Publication. 由此,在上述公开专利公报中揭示的LED 电灯中,无法满足抑制LED电灯大型化及点灯电路过热的要求。 Thus, LED lamp disclosed in the above Patent Publication, the LED lamp can not satisfy suppressed and the lighting circuit size requirements overheating.

绝缘构件6从收容部12的开口端12a嵌入收容部12内。 An insulating member 6 from the open end of the housing portion 12 fitted into the housing portion 12 12a. 由此,绝缘构件6的周壁部32a覆盖外层构件2周壁8的内周面,并且绝缘构件6的封闭壁部32b覆盖外层构件2的端壁9的内面。 Accordingly, the insulating member 32a of the peripheral wall portion 6 covers the inner circumferential surface of the outer peripheral wall 8 of the member 2, and the closing wall portion 32b of the insulating member 6 covers the inner surface of the end wall of the outer member 2 9. 因此,绝缘构件6将外层构件2和点灯电i?各5隔开。 Accordingly, the insulating member 6 to the outer member 2 and the lighting circuit I? 5 spaced apart from each.

灯座7用于将电流供给到点灯电路5。 The socket 7 for supplying current to the lighting circuit 5. 灯座7包括金属制灯座外壳35 和固定在灯座外壳35的连接构件36。 The socket 7 comprises a base housing 35 made of a metal and fixed in the base member 3635 is connected to the housing. 灯座外壳35以可拆除的方式拧入未图示的照明器具的灯插座。 The base housing 35 in a removable manner (not shown) is screwed into a lamp socket of a lighting fixture. 连接构件36是使用有例如聚对笨二甲酸丁二酯般合成树脂材料的成型品,且具有电绝缘性。 Connecting member 36 is used for example poly stupid acid polybutylene terephthalate resin molded article as synthetic material, and having electrical insulation property. 连接构件36形成为中空圆筒状,并且包括圓弧状弯曲的外周面36a。 Connecting member 36 is formed into a hollow cylindrical shape, and includes a curved arc-shaped outer circumferential surface 36a.

如图2所示,连接构件36包括嵌入收容部12的开口端12a内侧的前端部37。 2, the connector receiving member 36 includes a fitted portion 12a inside the open end 37 of distal portion 12. 在前端部37的外周面形成扣合突起38。 Engaging projection 38 is formed on the outer circumferential surface of the distal end portion 37. 扣合突起38在将前端部37嵌入到开口端12a内侧时与扣止槽8a扣合。 Engaging projection 38 with the locking button when the distal end portion 37 fitted into the open end 12a engaging the inner groove 8a. 通过此扣合,外层构件2和灯座7以同轴状连接。 By this engagement, the outer member 2 and the socket 7 are connected coaxially. 进而,连接构件36介于灯座外壳35与外层构件2 之间,且上述两者之间电绝缘且热绝缘。 Further, the connecting member 35 and base housing 36 is interposed between the outer member 2, and the above-described electrically insulating and thermally insulating therebetween.

在连接构件36连接于外层构件2的状态下,连接构件36外周面36a 与外层构件2的散热面10连接。 In the state of the connection member 36 is connected to the outer member 2, an outer circumferential surface of the connecting member 36 and outer member 36a radiating surface 10 of the second connector. 进而,在前端部37的根部部分形成阶差部39。 Further, the step portion 39 is formed at the distal end portion 37 of the root portion. 阶差部39包括扁平面,其在连接构件36圆周方向延续,并且在连接构件36的直径方向延伸。 Stepped portion 39 includes a flat surface which continues in the circumferential direction of the connection member 36, and extends in the diameter direction of the connecting member 36. 当将连接构件36的前端部37插入到收容部12 的开口端12a时,阶差部39会4妾触到开口端12a。 When the distal end portion of the connecting member 36 is inserted into the open end 37 of housing portion 12 when 12a, the stepped portions 39 will touch the open end 4 concubine 12a. 由此,对收容部12而言, 连接构件36的前端部37的插入量会受到限制。 Thus, portions of the housing 12, the insertion amount of the distal end portion 37 of the connecting member 36 is restricted.

同时,限制前端部37的插入量,由此将会在此连接构件36的前端部37和绝缘构件6的周壁部32a之间产生空隙S。 At the same time, limiting the amount of insertion of the distal end portion 37, whereby the distal end portion of the connection will be of the member 36 and the insulating member 37 to produce a gap between the peripheral wall portion 32a 6 of S. 由于存在有空隙S,例如当扣合突起38与扣止槽8a扣合前,可消除前端部37对绝缘构件6产生干扰这一不良情形。 Because there is a gap S, for example, when the engaging projection 38 with the front hitching engaging groove 8a, distal portion 37 may eliminate the insulating member 6 interfere with this negative situation. 换言之,可防止伴随连接构件36以及外层构件2的尺寸公差(dimensional tolerance)产生扣合突起38和扣止槽8a的扣合不良。 In other words, prevented from accompanying the dimensional tolerance (dimensional tolerance) connected to the outer member 36 and the engaging member 2 is generated and the hitching projection 38 engaging groove 8a failure. 由此,可将灯座7牢固地连接在收容部12的开口端12a。 Thereby, the socket 7 may be firmly connected at the opening end 12a of the housing portion 12.

在第1实施形态的灯1中,如果使灯1点灯,则发光二极管18将会发热。 In the first embodiment of the lamp 1, when the lamp 1 is lit, the LED 18 will generate heat. 发光二极管18除可通过在透明罩4内产生的空气对流而加以冷却外, 还可通过以下方式进行冷却。 In addition to the light emitting diode 18 may be cooled by air convection inside the transparent cover 4, but also cooling in the following manner.

发光二极管18所发出的热,通过配线板19传递到外层构件2的光源支撑部11。 Heat emitted by the light emitting diode 18, is transmitted to the light source supporting portion 11 of the outer member 2 through the wiring board 19. 传递到光源支撑部11的热,从端壁9通过周壁8传递到散热面10,且通过散热面IO散发到灯1外部。 The heat transferred to the supporting portion 11 of the light source 9 is transmitted through the peripheral wall from the end wall 8 to the heat dissipation surface 10, and emitted to the outside of the lamp 1 through the heat dissipation surface IO.

接受发光二极管18所发出的热的光源支撑部11,其是与具有散热面10的周壁8成形为一体。 The light source support portion receives heat emitted from the light emitting diode 18, 11, which is a peripheral wall 8 having a heat radiating surface 10 formed integrally. 故而,在从光源支撑部11到散热面10的热传导路径上不会存在有防碍热传导的接合部分,从而可将热传导路径的热阻抑制为较小。 Therefore, it will not be present in the heat conduction path from the light source 11 to the supporting portion 10 of the heat dissipation surface with an engaging portion hinder thermal conduction, whereby the thermal resistance of the heat conduction path can be suppressed to be small. 因此,可将传递到光源支撑部11的发光二极管18的热高效率地散发到散热面10。 Thus, the light emitting diode may be transmitted to the light source supporting portion 11 is efficiently thermally dissipated to the heat sink 18 of the surface 10.

此外,第1实施形态中,在外层构件2的端壁9形成包围光源支撑部11的环状的凹部14,此凹部14在外层构件2的外方开口。 Further, in the first embodiment, the concave portion 14 is formed to surround the annular light source supporting portion 11 of the outer member 2 of the end wall 9, this recess 14 in the outer member 2 of the outer opening. 由此,通过存在有凹部14而可增大外层构件2的表面积,尽管从灯1的外观要求而需限 Accordingly, by the presence of the concave portions 14 can increase the surface area of ​​the outer member 2, despite the appearance of the lamp in claim 1 and need limit

制外层构件2的形状,但是仍可增大外层构件2的散热量。 The outer member 2 made of a shape, but may still increase the amount of heat the outer member 2.

此结果,可提高发光二极管18的冷却性能,且可防止发光二极管18 过热。 This result, can improve the cooling performance of the light emitting diode 18, light emitting diode 18 and prevents overheating. 因此,可抑制发光二极管18的发光效率下降并且可使发光二极管18 的寿命延长。 Thus, the efficiency of light emitting diode 18 is suppressed decrease in the life and light emitting diode 18 can extend.

此外,因为发光二极管18安装在具有热扩散层23的配线板19上,所以发光二极管18所发出的热将会通过配线板19的热扩散层23而扩散到配线板19的各个角落。 Further, since the light emitting diode 18 is mounted on the wiring board having the thermal diffusion layer 23 is 19, the heat emitted by the light emitting diode 18 will be diffused to every corner of the wiring board 19 by the thermal diffusion layer 23 of the wiring board 19 . 因此,可将发光二极管18所发出的热从配线板19的较广范围传递到光源支撑部11。 Thus, the heat emitted by the light emitting diode 18 can be passed from a wide range of wiring board 19 to the light source supporting portion 11. 因此,热将会良好地从发光二极管18传导到光源支撑部11,且可使发光二极管18的冷却性能进一步提高。 Accordingly, the heat will be well conducted from the LED 18 to the light source supporting portion 11, and the cooling performance of the light emitting diode 18 can be further improved.

另外,第1实施形态的灯1在外层构件2内侧具有收容点灯电路5的收容部12。 Further, the first embodiment of the lamp 1 has a housing portion 12 accommodating the lighting circuit 5 in the inner side of the outer member 2. 由此,无须将外层构件2与点灯电3各5相互并列配置在灯1的轴向上。 Thus, without the outer member 2 and the lighting circuit 3 of each 5 parallel to each other in the axial direction of the lamp 1. 因此,可使灯l的轴向长度变短,且可提供小型的灯l。 Thus, the axial length l, the lamp can be shortened, and may provide a small lamp l.

与此同时,收容在收容部12的点灯电路5,通过绝缘构件6与外层构件2电绝缘。 At the same time, the lighting circuit 5 accommodated in the accommodating portion 12, 6 and 2 are electrically insulated by an insulating member outer member. 由此,可通过用金属制造的外层构件2而提高散热性能,并且可将点灯电路6装入外层构件2内部。 Accordingly, the heat dissipation performance can be increased through the outer member 2 made of metal, the lighting circuit 6 and may be loaded inside the outer member 2.

使外层构件2与点灯电路5之间电绝缘的杯形绝缘构件6是合成树脂材料的成型品,导热性低于外层构件2。 An electrically insulating member between the outer layer 52 and the lighting circuit 6 is cup-shaped insulating member molded article, thermally conductive synthetic resin material than the outer member 2. 因此,可从外层部材2热遮蔽点灯电路5,且抑制发光二极管18所发出的热从外层构件2传递到点灯电路5。 Accordingly, the shielding member 2 from the outer heat lighting circuit 5, and suppress the heat emitted from the light emitting diode 18 from the outer member 2 is transmitted to the lighting circuit 5. 其结果,可保护点灯电路5使其与从发光二极管18所发出的热隔开。 As a result, the lighting circuit 5 so as to protect spaced heat emitted from the light emitting diode 18. 由此, 可防止点灯电路5的错误操作,并且可使点灯电路5的寿命延长。 This prevents erroneous operation of the lighting circuit 5, and can extend the life of the lighting circuit 5.

收容点灯电路5的收容部12,由外层构件2、周壁8和端壁9包围,并且收容部12的开口端12a被灯座7封闭。 An accommodating part accommodating the lighting circuit 5 of 12, 2, the peripheral wall 8 and the end wall surrounded by an outer member 9, housing portion 12 and the opening end 12a of the socket 7 is closed. 换言之,点灯电路5收容在由外层构件2和灯座7所隔开的空间内,且灯1外部的空气流不会流经此空间。 In other words, the lighting circuit 5 is accommodated in the space formed by the outer member 2 spaced apart and the socket 7, and the external light does not flow through this air flow space. 由此,可避免导致产生漏电现象(tracking)的空气中灰尘附着在点灯电路5上。 Thereby, resulting in leakage phenomenon can be avoided (Tracking) air dust adhering to the lighting circuit 5.

图6以及图7揭示本发明第2实施形态。 6 and 7 discloses a second embodiment of the present invention.

此第2实施形态,关于外层构件2以及透明罩4的事项与上述第1实施形态不同。 This second embodiment, on matters of the outer member 2 and the transparent cover 4 of the first embodiment is different. 此外,灯1的结构以及由此结构所获得的有益技术效果与第1 实施形态相同。 Further, the structure of the lamp 1 structure, and thereby the advantageous technical effects obtained with the same as the first embodiment. 因此,第2实施形态中,对与第1实施形态同一结构部分付与同一参照符号,且省略其说明。 Thus, the second embodiment, the same pay moiety of the first embodiment and the same reference numerals, and description thereof is omitted.

如图6以及图7所示,第2实施形态的灯1中,外层构件2的周壁8 的外径,除了与外层构件2的收容部12的开口端12a邻接的端部以外,周壁8的外径都是固定的。 6 and 7, in the second embodiment of the lamp 1, the outer diameter of the peripheral wall 8 of the outer member 2, except for the end portion of the outer member 2 and the accommodating portion of the open end 12a of the adjacent peripheral wall 8 are fixed outside diameter. 因此外层构件2形成为直圆筒状。 Thus the outer member 2 is formed as a straight cylindrical shape.

再者,作为透明罩4的球状体包括反射部41a和投射光部41b。 Further, the transparent cover 4 comprises a spherical reflecting portion 41a and a light projection part 41b. 反射部41a包括朝向光源支撑部11开口的开口42a及决定此开口42a的缘部42b。 Reflecting portion 41a includes an opening 11 opening toward the light source support portion 42a, and this determines the opening edge portions 42a 42b. 缘部42b嵌入外层构件2的凹部14中。 Edge portion 42b fitted in the recess portion 14 of the outer member 2. 反射部41a形成为以从缘部42b开始直径逐次增加的方式扩展开的锥形。 Reflecting portion 41a is formed to start from the diameter of the edge portion 42b extend sequentially increased apart tapered manner. 在此反射部41a的内面层叠有光反射膜43。 The reflecting surface 41a of the inner light reflection film 43 is laminated.

投射光部41b以与反射部4ia连接的方式和反射部41a形成为一休。 Light projection part 41b to 41a is formed with the reflective portion mode and connected to the reflective portion is a break 4ia. 投射光部41b与光反射膜43及发光二极管18相对。 Light projection part 41b and the light reflection film 43 and the light emitting diode 18 opposite.

可通过如此形状的透明罩4,使用光反射膜43使从发光二极管18放射的部分光向投射光部41b反射。 4 can, using the light reflection film reflects the light emitted from the light emitting diode 18 to the projection portion of the light portion 41b through the transparent cover 43 of such a shape. 因此,利用投射光部41b使从发光二极管18放射的大部分光线进行聚光,并将其投射到灯1的外部。 Thus, with the projection portion 41b so that the light condenses most of the light from the light emitting diode 18 is radiated, and it is projected to the outside of the lamp 1.

如图7所示,外层构件2在由周壁8和端壁9所决定的角部设置有止动部45。 7, the outer member 2 is provided with a stopper portion 45 at the corner portion 9 is determined by the peripheral wall 8 and the end wall. 止动部45形成为从周壁8的内周面突出,并且与周壁8的圓周方向连接的环状。 An annular stopper portion 45 is formed to protrude from the inner peripheral surface of the peripheral wall 8 and is connected to the circumferential direction of the peripheral wall 8. 止动部45并非限定于环状。 The stopper 45 is not limited to the annular portion. 例如,可将从周壁8内周面突出的多个止动部以隔开间隔的方式配置在周壁8的圆周方向。 For example, a plurality of peripheral walls from the stopper portion 8 of the circumferential surface of the protrusion arranged in a manner spaced apart in the circumferential direction of the peripheral wall 8.

止动部45内径小于绝缘构件6的封闭壁部32b的外径。 45 the inner diameter of the stopper portion 32b is smaller than the outer diameter of the closure wall portion 6 of the insulating member. 因此,即使在将绝缘构件6嵌入外层构件2的收容部12的状态下,止动部45亦介于端壁9与绝缘构件6的封闭壁部32b之间。 Thus, even in a state where the insulating member 6 embedded in the outer member 2 of the housing member 12, the stopper portion 45 is also interposed between the end closure wall portion 32b and the wall 9 of the insulating member 6. 其结果,端壁9上的光源支撑部11与绝缘构件6相互隔开,且在上述两者之间存在有空隙46。 As a result, the light source supporting portion 9 on the end wall 11 spaced from each other and the insulating member 6, and between them there is a gap 46 above.

根据第2实施形态的灯1,由于存在有空隙46,可将接受到发光二极管18的热的光源支撑部11保持在与绝缘构件6为非接触的状态。 According to the second embodiment of the lamp 1, due to the presence of voids 46, you may receive the light emitting diode 18 of the heat source supporting portion 11 and the insulating member 6 held in a non-contact state. 因此,空隙46将会作为防碍热从光源支撑部11传递到绝缘构件6的隔热用空间而发挥作用,发光二极管18所发出的热将会难以直接从光源支撑部11传递到绝缘构件6。 Thus, the gap 46 will interfere with heat transfer from the light source as the support portion 11 to the heat insulating member 6 with a space to function, the heat emitted by the light emitting diode 18 would be unlikely to be transmitted directly from the light source supporting portion 11 of the insulating member 6 .

因此,尽管外层构件2内部收容的点灯电路5会接受到由发光二极管18所发出的热,仍可将对点灯电路5的热影响抑制为极小。 Thus, although the outer member 2 housed inside the lighting circuit 5 will receive the heat emitted by the light emitting diode 18, the thermal effect is still the lighting circuit 5 will be suppressed to a minimum. 故而,可防止点灯电路5的错误搡作,并且可使点灯电路5的寿命延长。 Therefore, possible to prevent erroneous lighting circuit 5 for shoving, and can extend the life of the lighting circuit 5.

图8揭示本发明第3实施形态。 FIG 8 discloses a third embodiment of the present invention.

此第3实施形态,相对于外层构件2的透明罩4的固定方法不同于上述第1实施形态。 This third embodiment, the transparent cover with respect to the outer member 2 of 4 fixing method different from the first embodiment. 此外,灯1的结构以及由此结构所获得的有益技术效果与第1实施形态同样。 Further, the structure of the lamp 1 structure, and thereby the advantageous technical effects obtained in the first embodiment similarly. 因此,第3实施形态中,对与第1实施形态同一结构部分付与同一参照符号,且省略其说明。 Thus, in the third embodiment, the same pay moiety of the first embodiment and the same reference numerals, and description thereof is omitted.

如图8所示,透明罩4的缘部4b,例如是通过硅系粘接剂51而固定在外层构件2的凹部14。 8, the edge portion of the transparent cover 4b 4, for example, the outer member is secured in the recess 142 by a silicon-based adhesive 51. 粘接剂51填充在凹部14内。 Adhesive 51 is filled in the concave portion 14. 凹部14以包围光源支撑部11的方式形成,且与固定配线板19的支撑面lla相比朝灯座7的方向凹陷。 Recessed portion 14 to surround the light source supporting portion 11 is formed, as compared with the support surface lla and fixing the wiring board 19 in the direction toward the recess 7 of the socket. 故而,与配线板19上的发光二极管18相比,粘接剂51设置在偏向灯座7方向的位置上。 Therefore, the light emitting diode on the wiring board 18 as compared to 19, the adhesive 51 provided at a position offset from the socket 7 direction.

根据第3实施形态的灯1,将透明罩4固定在外层构件2的粘接剂51, 其填充在比光源支撑部11的支撑面lla更加凹陷的凹部14内。 According to the third embodiment of the lamp 1, the transparent cover 4 is fixed to the outer member 2, an adhesive 51 is filled in a concave portion than the support surface lla light source supporting portion 11 of the recess 14 more. 故而,从发光二极管18放射的光将会难以直接射入粘接剂51。 Therefore, the light emitting diode 18 would be difficult to direct radiation incident on the adhesive 51. 因此,即使发光二极管 Thus, even if the light emitting diode

18放射的光中含有紫外线,也可防止粘接剂51的劣化。 Light 18 contains ultraviolet radiation, it can be prevented the deterioration of the adhesive 51. 从而可将透明罩4 长期牢固地保持在外层构件2上。 The transparent cover 4 so as to be firmly held on a long outer member 2.

图9至图11揭示本发明第4实施形态。 9 to FIG. 11 discloses a fourth embodiment of the present invention.

此第4实施形态中,外层构件2的光源支撑部11形状不同于上述第3 实施形态。 In this fourth embodiment, the shape of the light source supporting portion 11 of the outer member 2 is different from the third embodiment. 此外,灯1的结构以及由此结构所获得的有益技术效果与第1 实施形态同样。 Further, the structure of the lamp 1 structure, and thereby the advantageous technical effects obtained in the first embodiment similarly. 因此,第3实施形态中对与第1以及第3实施形态中同一结构部分付与同一参照符号,且省略其说明。 Thus, the third embodiment of the first aspect and the third embodiment in the same moiety imparting the same reference numerals, and description thereof is omitted.

如图9至图11所示,外层构件2的端壁9具有从光源支撑部11朝向透明罩4突出的凸部61。 As shown, the end wall 9 of the outer member 2 has four protruding portions 61 projecting from the support portion 11 toward the light source 9 to the transparent cover 11. 凸部61形成为小于光源支撑部11 一圏的圓盘状。 Projecting portions 61 formed smaller than the source disk-shaped support portion 11 of the rings of a. 凸部61与端壁9形成为一体,并且通过安装有透明罩4的凹部14而包围为同轴状。 Convex portion 61 and the end wall 9 is formed integrally, and mounted through the recessed portion 14 of the transparent cover 4 is surrounded coaxially. 故而,在凸部61与光源支撑部11之间形成一个阶差部62。 Therefore, a step portion 62 is formed between the convex portion 61 and the light source supporting portion 11. 阶差部62形成为于凸部61的圆周方向连续的圓环状。 Stepped portion 62 is formed in the circumferential direction of the convex portion 61 of the continuous annular.

在凸部61的前端形成平坦的支撑面63。 Flat support surface 63 formed at the front end of the convex portion 61. 支撑面63与外层构件2的端壁9相比更进入透明罩4内侧。 End walls 63 and the support surface 9 of the outer member 2 further enters inside the transparent cover 4 compared. 由此,支撑面63 3巨离凹部14的程度与上述凸部61高度相当。 Thus, the support surface 633 from the degree of giant recess 14 with the convex portion 61 highly comparable.

第4实施形态中,安装有发光二极管18的配线板19通过螺丝钉26固定在支撑面63的中央部。 In the fourth embodiment, a wiring board mounted with a light emitting diode 18 through the central portion 19 of the screw 26 is fixed to the support surface 63. 配线板19热连接于支撑面63。 Wiring board 19 is connected thermally to the support surface 63. 进而,螺孔15以及通孔16a、 16b贯穿凸部61而在支撑面63开口。 Further, screw holes 15 and the through holes 16a, 16b through an opening in the convex portion 61 and the supporting surface 63.

根据第4实施形态的灯1,在外层构件2的光源支撑部11形成向透明罩4突出的凸部61,在此凸部61的前端面63固定了具有发光二极管18的配线板19。 According to a fourth aspect of the lamp 1, the front end face of this convex portion 61 is fixed to the projection 63 of the projecting portion 61 is formed in the transparent cover 4 the light source support portion 11 of the outer member 2 a wiring board 19 having the light emitting diode 18. 因此,发光二极管18以与外层构件2的端壁19相比更进入透明罩4内侧的方式而偏移。 Thus, the light emitting diodes 18 enters the transparent cover 4 in a manner more inward of the outer member 2 and the end wall 19 of the offset. 因此,可将从发光二极管18放射的光高效率地导入到透明罩4内侧,进而散发到透明罩4的外部。 Thus, the light emitting diode 18 can be emitted from the light efficiently introduced into the inside of the transparent cover 4, and further radiated to the outside of the transparent cover 4.

再者,由于存在有凸部61,因此光源支撑部11的表面积以及热容量增加。 Furthermore, the presence of the convex portion 61, and therefore the surface area of ​​the light source support portion 11 and the heat capacity increases. 由此,尽管从灯1外观要求而限制了外层构件2的形状,但是仍可增加外层构件2的散热量。 Thus, despite the appearance of the lamp in claim 1 and outer member 2 limit the shape, but the amount of heat may be added by the outer member 2. 其结果可提高发光二极管18的冷却性能,抑制发光效率的下降,并且可使发光二极管18的寿命延长。 As a result, the cooling performance can be improved light emitting diode 18, to suppress a decrease in luminous efficiency and lifetime of the light emitting diode 18 can extend.

与此同时,发光二极管18距离填充在凹部14的粘接剂51的程度与凸部61的突出高度相当。 At the same time, the light emitting diodes 18 protruding from the filling height considerable extent the adhesive portion 51 of the recess 14 and the projecting portion 61. 换言之,从发光二极管18朝向凹部14的光被凸部61的外周部遮断,且从发光二极管18放射的光难以直接入射到粘接剂51。 In other words, the light is blocked by the outer peripheral portion of the convex portion 61 from the LED 18 toward the concave portion 14, and difficult incident from the light emitting diode 18 is directly radiated to the adhesive 51.

因此,即使在从发光二极管18放射的光中含有紫外线,也可防止粘接剂51的劣化。 Thus, even in an ultraviolet light emitted from the light emitting diode 18, it is also possible to prevent deterioration of the adhesive 51. 因此,可将透明罩4长期牢固地保持在外层构件2上。 Accordingly, the transparent cover 4 can be securely held on the long outer member 2.

图12揭示本发明第5实施形态。 FIG 12 discloses a fifth embodiment of the present invention. 实施形态同样。 The same embodiment. 因此第5实施形态中,对与第2实施形态同一结构部分付与同一参照符号,且省略其说明。 Thus the fifth embodiment, the same pay moiety of Embodiment 2 and the same reference numerals, and description thereof is omitted.

如图12所示,外层构件2的端壁9具有从光源支撑部11朝向透明罩4 突出的凸部71。 As shown, the end wall 9 of the outer member 2 has a convex portion 4 protrudes from the support portion 11 toward the light source 7112 transparent cover. 凸部71形成为比光源支撑部11小一圈的圓盘状。 Convex portion 71 formed in a disk shape than the light source supporting portion 11 is slightly smaller. 凸部71 与端壁9形成为一体,并且由嵌入透明罩4的凹部14包围为同轴状。 Convex portion 71 and the end wall 9 is formed integrally, embedded in a transparent cover and a recess portion 144 is surrounded coaxially. 故而, 在凸部71与光源支撑部11之间形成一个阶差部72。 Therefore, a step portion 72 is formed between the convex portion 71 and the light source supporting portion 11. 阶差部72形成为在凸部71的圆周方向上连续的圓环状。 Stepped portion 72 formed as a continuous annular portion in the circumferential direction of the projections 71.

在凸部71前端形成平坦的支撑面73。 Flat support surface 73 formed in the front end of the convex portion 71. 支撑面73与外层构件2的端壁9相比更进入透明罩4的反射部41a的内侧。 73 and the end wall 9 of the outer member 2 enters the transparent cover more reflective compared to the inner portion 41a of the support surface 4. 由此,支撑面73距离凹部14 的程度相当于上述凸部71的高度。 Thus, the extent of the support 73 from the surface of the concave portion 14 corresponds to the height of the convex portion 71.

第5实施形态中,安装有发光二极管18的配线板19,其通过螺丝钉26固定在支撑面73的中央部。 In the fifth embodiment, a wiring board mounted with a light emitting diode 18, 19, which is fixed to the center portion of the support surface 73 by means of screws 26. 配线板19热连4妄于支撑面63。 19 thermal jump wiring board 4 is connected to the support surface 63. 进而,螺孔15以及通孔16a、 16b贯通凸部71且在支撑面73开口。 Further, screw holes 15 and the through holes 16a, 16b through an opening in the protrusion 71 and the support surface 73.

根据第5实施形态的灯1,发光二极管18与外层构件2的端壁19相比更进入透明罩4的反射部41a内侧。 According to a fifth aspect of the lamp 1, the light emitting diode 18 and the end wall 2 of the outer member 19 is more reflective portions 41a enters the transparent cover 4 compared to the inside. 故而,可将从发光二极管18放射的光高效率地导入透明罩4内侧。 Therefore, the light emitting diode 18 can be emitted from the light efficiently introduced into the inside of the transparent cover 4. 由此,可使来自发光二极管18的光通过光反射膜43而反射到透光部41b的方向,且可从透光部41b放射到透明罩4的外部。 Thus, from the outside of the light emitting diode can pass through the light reflection film 43 is reflected in the direction of the light-transmitting portion 41b, and is radiated from the light transmitting portion 41b of the transparent cover 18 to 4.

进而,由于存在有凸部71,故而可增大光源支撑部11的表面积以及热容量。 Furthermore, the presence of the convex portion 71, can therefore increase the surface area and the heat capacity of the support portion 11 of the light source. 因此,尽管考虑到灯1的外观要求,而限制外层构件2的形状,但是仍可增加外层构件2的散热量。 Thus, although the viewpoints of the appearance of the lamp in claim 1, the shape of the outer member 2 is limited, but the amount of heat may be added by the outer member 2. 其结果,可提高发光二极管18的冷却性且抑制发光效率下降,并且可使发光二极管18的寿命延长。 As a result, the cooling performance can be improved light emitting diode 18 is suppressed and the luminous efficiency decreases, and the life of the light emitting diode 18 can extend.

图13至图20揭示了本发明第6实施形态。 13 to FIG. 20 discloses a sixth embodiment of the present invention.

此第6实施形态与上述第1实施形态的不同点主要是,对外层构件2 的收容部12而言,点灯电路5的支撑方法不同。 This sixth embodiment of the first aspect of the embodiment is mainly different from, the lighting circuit 5 of the method for supporting different storage portion 12 in terms of the outer layer 2 of the member. 除此以外,灯1的结构以及由此结构所获得的有益的技术效果皆与第1实施形态同样。 In addition, the structure of a light structure and thus the advantageous technical effects obtained are similar to the first embodiment. 由此,第6 实施形态中,对于与第1实施形态相同的构成部分使用同一参照符号,且省略其it明。 Thus, in the sixth embodiment, the same as those of the first embodiment form of the components with the same reference numerals, and the description thereof is omitted it.

如图17至图19所示,在绝缘构件6的周壁部32a内周面一体形成有一对导向部87a、 87b。 17 to 19, in the inner peripheral surface of the peripheral wall 32a of the insulating member 6 is integrally formed with a pair of guide portions 87a, 87b. 导向部87a、 87b在周壁部32a的直径方向上相对,并且从周壁部32a的内周突出。 The guide portion 87a, 87b diametrically opposite peripheral wall portion 32a, and protrudes from the inner periphery of the peripheral wall portion 32a. 并且,导向部87a、 87b沿周壁部32a的轴向延伸。 Further, the guide portions 87a, 87b extending along the axial direction of the peripheral wall portion 32a.

在各导向部87a、 87b形成扣合槽88。 In each of the guide portions 87a, 87b are formed engagement grooves 88. 扣合槽88中以可滑动的方式嵌合有配线板28的第1以及第2缘部81a、 81b,且一直沿周壁部32a的轴向延伸。 The engagement groove 88 to be slidably fitted into the first and second edge portions 28 of the wiring board 81a, 81b, and extends in the axial direction of the peripheral wall portion 32a. 扣合槽88 —端由绝缘构件6的封闭壁部32b封闭。 Engagement groove 88-- end by a closing wall portion 32b of the insulating member 6 is closed. 扣合槽88的另一端向周壁部32a的另一端开口。 The other end of the engagement groove 88 is open toward the other end of the peripheral wall portion 32a.

为了将点灯电路5装入收容部12,将配线板28的第3缘部81c作为前端,在此状态下将配线板28插入到绝缘构件6的周壁部32a内侧。 In order to mount the lighting circuit 5 receiving portion 12, the third edge portion 81c of the wiring board 28 as a front end, in this state, the wiring board 28 is inserted into the insulating member 32a inside the peripheral wall portion 6. 此配线板28的插入操作,其是将该配线板28的第1以及第2缘部81a、 81b插入到扣合槽88。 This insertion wiring board 28, the first and second edge portions 81a of the wiring board 28, 81b is inserted into the engagement groove 88. 当配线板28插入到周壁部32a内侧后,则配线板28的第3 缘部81c将会接触到绝缘构件6的封闭壁部32b。 When wiring board 28 is inserted into the inside of the peripheral wall portion 32a, the wiring board 28 of the third edge portion 81c of the insulating member will be exposed to the closed portion 6 of the wall 32b. 因此,无需进行特别的考虑而可以决定配线板28对绝缘构件6的插入量。 Therefore, no special considerations may determine the amount of the insulating member 6 inserted into the wiring board 28. 因此,将点灯电路5装入收容部12的操作性较良好。 Accordingly, the lighting circuit 5 is charged with the housing portion 12 relatively good operability.

将配线板28插入到绝缘构件6的周壁部32a内侧之后,将灯座7的连接构件36连接到外层构件2的开口端12a。 After the wiring board 28 is inserted into the insulating member 6 inside the peripheral wall portion 32a of the connection member 36 of the socket 7 to the outer member 2 of the open end 12a. 通过此连接,使得连接构件36 的止动部85a、 85b与配线板28的第1及第2扣合部82a、 82b接触。 By this connection, so that the connecting member 36 of the stopper portion 85a, 85b and the first and second wiring board 2 of the engaging portion 82a 28, 82b in contact. 由此,配线板28可夹在外层构件2的端壁11和止动部85a、 85b之间,且可在周壁8的轴向不移动点灯电路5的方式保持该点灯电路5。 Thus, the wiring board 28 can be sandwiched between the outer member 11 and the end wall of the stopper portion 85a, 85b, and may be no way to move the lighting circuit 5 in the axial direction of the peripheral wall 8 of the lighting circuit 5 is maintained. 与此同时,因为配线板28的第1以及第2缘部81a、 81b嵌合在绝缘构件6的扣合槽88,所以可以在周壁8的圆周方向不移动点灯电踏5的方式而保持该点灯电路5。 At the same time, since the first and second edge portions 28 of the wiring board 81a, 81b is fitted in the insulating member of the engagement groove 886, depression can be electrically turned on without moving the embodiment 5 in the circumferential direction of the circumferential wall 8 while holding the lighting circuit 5. 进而,如果进一步加强配线板28的第1缘部81a和扣合槽88的嵌合,则可仅通过第1缘部28a和扣合槽88的嵌合而以在周壁8的圆周方向上不移动点灯电路5的方式而保持该点灯电路5。 Further, if the further strengthening of the first fitting portion 81a and the engaging edge 88 of the groove 28 of the wiring board, can be fitted to only the first edge portion 28a and the engaging grooves 88 in the circumferential direction of the peripheral wall 8 5 embodiment the lighting circuit is not moved while holding the lighting circuit 5.

从而,点灯电路5以不能移动的方式保持在外层构件2的收容部12中。 Accordingly, the lighting circuit 5 held immovable manner in the receiving portion 12 of the outer member 2.

如图13所示,点灯电路5的配线板28,将绝缘构件6的周壁部32a的内部沿直径方向隔开为两个区域89a、 89b。 As shown, the lighting circuit 5 of the wiring board 28, the inner insulating member 32a of the peripheral wall portion 13 spaced 6 in the diameter direction of the two regions 89a, 89b. 区域89a、 89b向灯座7的内侧空间90开口,并且通过此空间90而相互连通。 Area 89a, 89b toward the inside of the socket opening 90 of the space 7, and by the space 90 communicate with each other.

配线板28的第1以及第2面28a、 28b均不指向接受发光二极管18所发出的热的光源支撑部11,且与绝缘构件6的周壁部32a相对。 First and second wiring board 2 of the surface 28a 28, 28b not point to receive heat emitted from the light emitting diode 18 light source support portion 11, and the insulating member and the peripheral wall portion 32a 6 opposite. 故而,电路零件29的导线端子与配线板28的焊接部分,其可远离与光源支撑部11相接的绝缘构件6的封闭壁部32b,可抑制对焊接部分的热影响。 Therefore, the circuit part is welded portion of the wire terminal 29 and the wiring board 28, which may be remote from the light source supporting unit closure wall portion 11 of the insulating member 6 in contact 32b and suppress thermal influence on the welded portion.

进而,邻接于配线板28的第4缘部81d的电容器83,其进入灯座7内侧空间90,且远离于接受到发光二极管18所发出的热的光源支撑部11。 Further, adjacent to the fourth edge portion 81d of the wiring board 83 of the capacitor 28, the socket 7 into the inner space 90, and the received heat away from the light emitting diode 18 of the light source supporting portion 11. 故而,不耐热的电容器83将会难以受到发光二极管18所发出的热的影响,且可提高电容器83的持久性。 Therefore, the capacitor 83 will not heat is hardly affected by the heat emitted by the light emitting diode 18, and can improve the persistence of capacitor 83.

此外,因为点灯电i?各5的一部分进入灯座7内侧的空间90,故而可使绝缘构件6以及外层构件2的轴向上的长度变短。 Further, since the lighting circuit I? 5 portion of each of the socket 7 into the inner space 90, and therefore allows the axial length of the insulating member 6 and the outer member 2 is shortened. 由此,可有利于实现灯l 的小型化。 Thereby, it may facilitate downsizing of the lamp l. 如果外层部材2的轴向上的长度变短,则将会产生散热面10的面积减少这一弊端。 If the axial length of the outer member 2 is shortened, the heat dissipation surface area 10 will be generated to reduce this shortcoming. 作为其对策,也可通过将外层构件2的外径变大,而弥补此散热面10面积所减少的部分。 As a countermeasure, the outer diameter of the outer layer can also be member 2 increases, and this heat sink 10 to compensate the reduced area of ​​the surface portion.

如图13以及图16所示,安装在配线板28的第1面28a的电路零件29 会高于安装在第2面28b的芯片零件84。 As shown in FIG. 13 and FIG. 16, the circuit components mounted on the wiring board 28 of the first surface 28a is higher than 29 mounted on the second surface 28b of the chip part 84. 由此,本实施形态中所述的配线板28,其以第1面28a与绝缘构件6周壁部32a之间的区域89a大于第2 面28b与绝缘构件6周壁部32a之间的区域89b的方式,而对于灯1中心线XI进行偏移。 Thus, the present embodiment aspect of the wiring board 28, which is the region 89a between the first surface 28a of the insulating member 6 larger than the area of ​​the peripheral wall portion 32a of the wall portion 32a between the six weeks of the second insulating member 28b and the surface 89b manner, while the lamp centerline offset XI.

其结果是,可使较高的电路零件29尽可能地远离外层构件2的周壁8, 电路零件29将会难以受到传递到周壁8的由发光二极管18所发出的热影响。 As a result, it allows higher circuit component 29 away from the outer peripheral wall 8 of member 2 as much as possible, the circuit component 29 is difficult to be affected by the heat transferred to the peripheral wall 8 of the light emitting diode 18 is emitted. 与此同时,即使在第2面28b与外层构件2周壁8之间设有区域89b, 也可于某种程度上确保容积。 At the same time, even in the circumferential wall 2 between the second surface 28b and the outer member 8 has a region 89b, the volume can be ensured to some extent. 由此,即使电路零件29的导线端子从配线板28的第2面28b向区域89b突出,导线端子亦难以受到传递到周壁8的由发光二极管18所发出的热影响。 Accordingly, even if the lead terminals 29 of the circuit part 28b protruding from the second surface of the wiring board 28 to the area 89b, the lead terminal is also affected by the heat transferred to the hard peripheral wall 8 of the light emitting diode 18 is emitted. 从而,可防止导线端子和配线板28的焊4妻部分根据第6实施形态中的灯1,点灯电路5的配线板28是以第1以及第2面28a、 28b分别与绝缘构件6的周壁部32a的内周面相对的状态,而容纳在外层构件2的收容部12中。 Accordingly, the welding portion 4 is prevented wife lead terminals 28 and the wiring board according to a sixth embodiment of a lamp lighting circuit 28 is a wiring board 5 of the first and second surfaces 28a, 28b, respectively, and the insulating member 6 the inner circumferential surface 32a of the peripheral wall portion opposite to, and received in the receiving portion 12 of the outer member 2. 因此,配线板28的第1面28a或者第2 面28b不会与绝缘构件6的封闭壁部32b相对。 Thus, the first surface of the wiring board 28 closing wall portion 32b 28a 28b or the second surface of the insulating member 6 is not opposed.

因此,无需在配线板28与封闭壁部32b之间形成大致密封的空间,点灯电路5所发出的热或从发光二极管18传递到光源支撑部11的热亦难以聚集在邻接于光源支撑部11的收容部12的端部。 Thus, no need to form a substantially sealed space between the wiring board 28 with the closing wall portion 32b, the lighting circuit 5, the heat emitted by a light emitting diode or the heat transmitted from the light source 18 to the support portion 11 also difficult to gather in a portion adjacent to the light source support accommodating portion 11 of the end portion 12. 从而,可防止光源支撑部11过热,且可有利于提高发光二极管18的冷却性能。 Thus, prevented from overheating the light source supporting portion 11, and can help to improve the cooling performance of the light emitting diode 18.

此外,因为配线板28从外层构件2跨过灯座7,所以配线板28的尺寸不会受到绝缘构件6内径的限制。 Further, since the wiring board 7 from the outer layer 28 across the socket member 2, the size of the wiring board 28 is not limited by the inner diameter of the insulating member 6. 由此,可增加决定配线板28的尺寸或者增大将电路零件29布置在配线版28上的自由度,且可易于进行点灯电路5 的电^各设计。 Thus, determine the size of the wiring board 28 can be increased or increasing the degree of freedom of the circuit components 29 disposed on the wiring plate 28, and may be readily electrically lighting circuit 5 ^ each design.

进而,第6实施形态中揭示了防止外层构件2与导线30a、 30b之间产生短^^的结构。 Further, the sixth embodiment discloses prevent the outer member 2 with the wire 30a, is generated between the structural staple ^^ 30b.

如图14以及图15所示,位于光源支撑部11的一对通孔16a、 16b分别具有小径部91、大径部92、以及阶差部93。 As shown in FIG. 14 and FIG. 15, a light source positioned pair of through holes 11 of the supporting portion 16a, 16b each having a small-diameter portion 91, the large-diameter portion 92, and a stepped portion 93. 阶差部93位于小径部91与大径部92的边界。 Stepped portion 93 at a boundary portion 91 and the small-diameter portion 92 of large diameter.

通孔16a、 16b中分别嵌合有绝缘筒94。 The through holes 16a, 16b are fitted in the insulating tube 94. 绝缘筒94例如由聚对苯二甲酸丁二酯这样具有电绝缘性的合成树脂材料制造。 For example polyethylene insulation barrel 94 having such electrically insulative synthetic resin for producing polybutylene terephthalate material. 绝缘筒94跨过小径部91 和大径部92从而覆盖通孔16a、 16b内面。 Across the small-diameter portion 94 of the insulating tube 91 and the large diameter portion 92 so as to cover the through holes 16a, 16b inner surface.

绝缘筒94具有穿过导线30a、 30b的插通孔95。 Insulation barrel 94 having a through wire 30a, 30b of the insertion hole 95. 插通孔95连接于绝缘构件6的贯通孔33a、 33b。 The insertion hole 95 is connected to the through hole 6 of the insulating member 33a, 33b. 如图15所示,与插通孔95的贯通孔33a、 33b 邻接的开口边缘,其利用直径通过切面(chamfering)而得到扩展。 15, the insertion hole of the through hole 95, 33b adjacent the edge of the opening 33a, through which section (Chamfering) obtained using the expanded diameter. 由此, 可在将导线30a、30b从贯通孔33a、33b导入到插通孔95时,防止导线30a、 30b卡在插通孔95的开口边缘。 Thereby, the wire can 30a, 30b is introduced from the through hole 33a, 33b to the insertion hole 95, to prevent the conductors 30a, 30b in the card insertion opening edge of the through hole 95.

绝缘筒94从光源支撑部11的支撑面lla方向嵌入到通孔16a、16b中。 The insulating tube 94 is fitted from the direction of the light source support surface lla of the support portion 11 into the through holes 16a, 16b in. 通过将配线板28固定在支撑面lla上,而使得绝缘筒94夹在该配线板28 与通孔16a、 16b的阶差部93之间。 By wiring board 28 fixed to the support surface lla, so that the insulation barrel 28 and 94 is interposed between the through holes 16a, the stepped portion 93 of the wiring board 16b. 由此,可将绝缘筒94保持在光源支撑部11上。 Thus, the insulating tube 94 may be held on the light source supporting portion 11. 从而,无需将绝缘筒94粘接在光源支撑部11上,且可易于进行灯1的组装操作。 Thus, without the insulating tube 94 is bonded on the light source supporting portion 11 and the assembling operation can be easily performed lamp 1.

导线30a、 30b具有例如使用铜线的芯线96、和覆盖此芯线96的绝缘层97。 Conductors 30a, 30b, for example, a copper wire having a core wire 96, this core wire and the insulating cover layer 97 is 96. 绝缘层97在导线30a、 30b的前端部被去除。 An insulating layer 97 in the wire 30a, 30b of the front end portion is removed. 因此,在导线30a、 30b的前端部,芯线96露出在绝缘层97的外部。 Thus, the wire 30a, 30b of the distal end portion, the core wire 96 exposed to the outside of the insulating layer 97. 露出的芯线96通过焊接等的方法而电性连接于配线板28。 The exposed core wire 96 is electrically connected to the wiring board 28 by means of welding or the like.

在去除绝缘层97时,如果在除去绝缘层97的范围内产生不均,则从绝缘层97露出的芯线96长度将会产生变动。 When removing the insulating layer 97, if unevenness, the insulating layer 96 from the exposed length of core wire 97 in the range of removing the insulating layer 97 will fluctuate. 因此,例如图15所示,在将导线30a从贯通孔33a导入通孔16a时,露出的芯线96可位于通孔16a内侧。 Thus, as shown in FIG. 15, the wire 30a from the through hole 33a introduced into the through hole 16a, the exposed core wire 96 can be positioned inside the through hole 16a. 嵌合在通孔16a中的绝缘筒94介于露出的芯线96和通孔16a之间,且使露出的芯线96和光源支撑部11之间电绝缘。 In the fitting between the through hole 16a of the insulating tube 94 is exposed between core wire 96 and the through holes 16a, and the support and the light source 96 so that the exposed portion of the core wire 11 is electrically insulated.

从而,可利用绝缘筒94防止露出的芯线96与光源支撑部11之间产生短路。 Thus, the insulating tube 94 may be utilized to prevent a short circuit between the core wire 96 and the light source supporting portion 11 is exposed.

露出的芯线96从插通孔95插入向配线板19打开的一对通孔98,并且穿过通孔98导入到配线板19上。 The exposed core wire 96 is inserted from the insertion hole 95 a pair of through holes 19 open to the wiring board 98, and passes through the through-hole 98 into the wiring board 19. 露出的芯线96前端焊接于形成在配线板19上的岛状区域(land)(未图示)。 The exposed core wire 96 is soldered to the distal end is formed in the island regions (Land) on the wiring board 19 (not shown).

点灯电路5的配线板28如上所述,偏移于灯中心线X1。 Lighting circuit 5 of the wiring board 28 as described above, offset from the centerline of the lamp X1. 由此,如图16 所示,可使各通孔98位于热扩散层23的相邻接的区域23a、 23b与23c、 23d之间。 Accordingly, as shown in Figure 16, the through holes 98 can positioned adjacent to the thermal diffusion layer 23 in the contact region 23a, 23b and between 23c, 23d. 由此,尽管通孔98贯穿配线板19,仍不会减少热扩散层23的面积。 Thus, although the through-hole 98 through the wiring board 19, still does not reduce the area of ​​the thermal diffusion layer 23. 从而,可将发光二极管18所发出的热通过扩散层23高效率地传递到光源支撑部11,且可抑制发光二极管18过热。 Thus, heat can be emitted from the light emitting diode 18 through the diffusion layer 23 is efficiently transmitted to the light source supporting portion 11, the light emitting diode 18 is suppressed and overheating.

首先,在外层构件101的收容部11嵌入绝缘构件106,并且在由此绝缘构件106覆盖的收容部116内侧收容点灯电路105。 First, the outer member 101 and the housing portion 11 embedded in the insulating member 106, and thereby the insulating member covering the housing portion 106,116 lighting circuit 105 accommodated inside. 其次,将从点灯电路105引出的两才艮导线162a、 162b/人封闭壁部163b的通孔导入到光源支撑部113的通孔122a、 122b。 Secondly, 162a, 162b / 163b person closing wall portion of the through hole into the through-hole 113 of the light source supporting portions 122a, 122b from only two lighting circuits 105 Gen drawn wire.

此后,将传热板135装载到光源支撑部113的支撑面114上,并且将光源102的底部125重叠在传热板135上。 Thereafter, the transfer plate 135 is loaded onto the support surface 114 of the light source supporting unit 113, the light source 102 and the bottom of the heat transfer plate 125 overlap 135. 此时,将光源支撑部113的凸部123a、 123b通过传热板135的滑动部136c、 136d而嵌入光源102的第l扣合部132a、 132b。 At this time, the projecting portion 113 of the light source supporting portions 123a, 123b and the engaging portion fitted in the first light source 102 l of 132a, 132b by the slide portion 135 of the heat transfer plate 136c, 136d. 由此,决定了光源102与光源支撑部113的相对位置。 Thus, it determines the relative position of the light source 102 and the supporting portion 113. 进而,将导入到通孔122a、 122b的导线162a、 162b通过光源102的导线插通部131a、 131b导入到邻接的两个岛状区域129,且焊接于上述岛状区域129。 Further, introduced into the through holes 122a, 122b of the wires 162a, 162b the light source 102 through the wire insertion portion 131a, 131b into the two adjacent island regions 129 and 129 welded to the island regions. 其次,将光源外罩103装载到光源102的配线板126上。 Next, the light source cover 103 is loaded onto the wiring board 126 of the light source 102. 此时,使从透镜固定器139突出的凸部151a、 151b嵌合到光源102的第2扣合部133a、 133b。 At this time, the convex portion protruding from the lens holder 139 151a, 151b fitted to the second engaging portion 102 of the light sources 133a, 133b. 通过此嵌合,决定了光源102与光源外罩103的相对位置。 By this fitting, determines the relative position of the light source 102 and the housing 103. 从而,透镜138的光轴X2将会和发光元件127的中心相一致,并且透镜固定器139 的接受部150会抵触到配线板126的外周部。 Thus, the optical axis X2 of the lens 138 and the center of the light emitting element 127 will be consistent, the lens holder 139 and the receiving portion 150 would be contrary to the outer peripheral portion 126 of the wiring board.

其次,通过将外罩固定器104的母螺紋部158拧入外层构件102的公螺纹部121,由此将此外罩固定器104以同轴状连接于外层构件101。 Then, by screwing the female screw member outer portion 158 of the housing 104 fixed portion 102 of the male thread 121, whereby this holder cover 104 is connected coaxially to the outer member 101. 伴随外罩固定器104的连接,外罩固定器104的挤压部155将会抵触到透镜固定器139的一端,且将透镜固定器139挤压向光源支撑部113。 Along fixed connector housing 104, the cover pressing portion 155 of the fixture 104 will conflict with one end fixed to the lens 139, a lens holder 139 and the pressing portion 113 to support the light source. 其结果,光源102通过透镜固定器139挤压到光源支撑部113的支撑面114,并且传热板135牢固地夹在支撑面114和光源102的底部125之间。 As a result, the light source 102 is pressed through a lens holder portion 139 to the support surface 114 supporting the light source 113, and the heat transfer plate 135 is firmly sandwiched between the bottom surface 114 of the support 125 and the light source 102.

由于传热板135产生弹性变形,因此将会紧贴于此支撑面114以及底部125。 Since the heat transfer plate 135 is elastically deformed, and therefore will be in close contact thereto, and a bottom surface 114 of support 125. 由此,排除防碍支撑面114与底部125间的热传导的空隙,且可使热在支撑面114与底部125之间进行良好地传导。 Thus, the support surface 114 and the negative hindering thermal conduction at the bottom 125 of the gap, and the heat can be conducted favorably between the support 114 and the bottom surface 125. 换言之,与没有使用传热板135的情形相比,可提高从光源102到光源支撑部113的导热性能。 In other words, compared with the case without the use of heat transfer plate 135 can improve heat transfer performance from the light source 102 to the light source supporting unit 113.

与此同时,通过使传热板135弹性恢复到原来形状的反弹力,使母螺紋部158和公螺紋部121的咬合变得强固。 At the same time, the heat transfer plate 135 by the elastic restoring force of rebound to its original shape, so that the female threaded portion engaging the threaded portion 158 and the male 121 becomes strong. 由此,外罩固定器104将会难以松弛。 Thus, the fixture 104 will be difficult to cover the slack.

例如在支撑面114以及底部125的精度较高的情形时,可省去传热板135。 For example, in the case of higher precision supporting surface 114 and a bottom 125, heat transfer plate 135 can be omitted. 进而,也可使用以例如硅为主成分的导电性油脂代替传热板135。 Further, conductive grease may also be used, for example instead of silicon as a main component of the heat transfer plate 135.

当光源102压向光源支撑部113时,随外罩固定器104的拧入而得的旋转力,将会作用于光源外罩103以及光源102。 When the light source when the light source 102 is pressed against the supporting portion 113, with the fixture 104 is screwed into the housing obtained rotational force will be applied to the light source 103 and a light source cover 102. 光源102如上所述,通过凸部123a、 123b与第l扣合部132a、 132b的嵌合,决定与光源支撑部113 之间的相对位置。 The light source 102 described above,, the relative position between the convex portions 123a 123b 113 and the second engaging portion 132a fitted l 132b, determines the light source support portion. 同样,即使为光源外罩103,也可通过凸部151a、 151b 和第2扣合部133a、 133b的嵌合来决定对光源102的相对位置。 Also, even if the light source cover 103, but also to determine the relative position of the light source 102 via 151a, 151b, and the second fitting engagement portion 133a, 133b of the projecting portion.

因此,光源外罩103以及光源102不会随着外罩固定器104而旋转。 Thus, the light source 103 and a light source cover 102 is not fixed to the housing 104. With the rotation. 从而,导致产生断线及裂缝的过大力量不会施加到光源102的岛状区域129 和导线162a、 162b的焊接部分。 Thereby, resulting in breakage and crack excessively large force is not applied to 162a, 162b of the welded portion 102 of the source region 129 and the island-shaped wire. 从而,不向导线162a、 162b与岛状区域129的焊接部分施加应力,亦可组装此灯IOO。 Thus, not to the wire 162a, 162b and the welded portion 129 of the island-shaped region a stress is applied, also this light assembly IOO.

其次,将灯座107安装在外层构件101。 Next, the socket 107 is mounted in the outer member 101. 安装作业以如下方式进行,即, 将灯座107的前端部169嵌入外层构件101的开口端116,并且使扣合突起170扣合在扣止槽118。 Mounting operation is performed as follows, i.e., the distal end portion 169 of the socket 107 fitted into the opening end 116 of the outer member 101, and the engaging projection 170 engaging locking groove 118 in the buckle.

当将灯座107安装在外层构件101时,点灯电路105有时会受到被灯座107的连接部材168挤压向光源支撑部113方向的力量。 When the socket 107 is mounted on the outer member 101, the lighting circuit 105 is sometimes subject to be pressed toward the direction of the light source supporting portion 113 member connection portion 168 of the power socket 107. 此力通过导线162a、 162b传递到光源102。 This force is transmitted to the light source 102 through a wire 162a, 162b.

光源102夹在光源外罩103与光源支撑部113之间。 The light source cover 102 interposed between the light source 103 and light source supporting portion 113. 因此,即使力通过导线162a、 162b施加到光源102,光源102亦不会脱离光源支撑部113 的支撑面114。 Thus, even if a force 162a, 162b is applied to the wire by a light source 102, light source 102 will not departing from the supporting surface 114 of the supporting portion 113. 因此,可维持光源102与光源支撑部113之间的紧密性,并且也可使透镜138的光轴X2不会偏离发光素子127中心。 Thus, the light source 102 may be maintained close to the light source supporting unit between 113 and 138 also allows the optical axis of the lens may not deviate from X2 emitting sub-pixel center 127.

最后,将隔热外罩108安装并固定在外层构件101以及外罩固定器104 的外侧,且将隔热外罩108的母螺紋部174拧入连接构件168的公螺紋部173。 Finally, the insulation cover 108 is mounted and fixed to the outside of the outer member 101 and a cover 104 is fixed, and the female screw portion 174 of the insulation cover 108 is screwed into the male thread portion 173 connecting member 168. 通过此拧入,隔热外罩108的扣合部175会卡在外罩固定器104的一端。 By this screwing, engaging portion 108 of the insulation cover 175 will be stuck in an end of the housing 104 of the fixture. 其结果,以同轴状包围隔热外罩108的外层部位101以及外罩固定器104的状态连接灯座107,从而完成灯100的组装。 As a result, state coaxially surrounds the outer insulation cover 101 and a cover portion 108 of the fixture 104 is connected to the socket 107, 100 to complete the assembly of the lamp.

在已完成组装灯100的状态下,将位于隔热外罩108内侧的散热通路176通过吸气口178以及排气口177而开放在大气中。 In the assembled state of the lamp 100 has been completed, the cooling passage 108 is located inside the insulation cover 176 and open to the atmosphere through the suction port 178 and the exhaust port 177.

第7实施形态的灯100中,若使灯100进行照明,则发光元件127将会发热。 100 seventh embodiment of the lamp, when the lamp 100 is illuminated, the light emitting element 127 will generate heat. 发光元件127所发出的热,会从光源102的底部125通过传热板135而传递到光源支撑部113。 Heat emitted from the light emitting element 127, 125 will be transmitted to the light source supporting unit 113 through the heat transfer plate 135 from the bottom of the light source 102. 传递到光源支撑部113的热从端壁110通过周壁110而传递到散热面112,且从该散热面112散发到散热通路176。 Heat transfer to the light source supporting portion 113 from the end wall 110 is transferred to the heat radiation surface 112 of the peripheral wall 110, and radiated from the heat radiating surface 112 to passage 176.

因为接受到发光元件127所发出的热的光源支撑部113,其与具有散热面112的周壁IIO成型为一体,故而在从光源支撑部113到散热面112的热传导路径上不存在防碍热传导的接合部分。 Because the received heat source supporting portion emitting component 127 113, with the peripheral wall IIO having a radiating surface 112 molded integrally, and therefore the absence hinder the heat conduction in the heat conduction path from the light source supporting unit 113 to the radiating surface 112 of the engaging portion. 所以,可将热传导路径的热阻抑制为较小,且可高效率地将传递到此光源支撑部113的发光元件127 所发出的热散发到散热面112。 Therefore, the thermal resistance of the heat conduction path can be suppressed to be small, and can be efficiently passed to the heat source supporting portion 113 of the light emitting element 127 is radiated to the emitted heat radiation surface 112. 与此同时,因为散热面112的全部表面皆露出于散热通路176,因此不会防碍从散热面112进行散热。 At the same time, since the entire surface of the heat dissipating surface 112 are exposed to the cooling passage 176, and therefore will not prevent heat radiated from the surface 112. 从而,可提高发光元件127的冷却性能。 Thereby, the cooling performance can be improved in the light emitting element 127.

进而,因为金属制外罩固定器104拧入外层构件101,因此可通过母螺紋部174与公螺紋部173的咬合部分使外层构件101与外罩固定器104热连接。 Further, since the metal housing 104 is screwed into the outer retainer member 101, 104 so that it can heat the holder member 101 and the outer housing by a snap connection portion 174 and the female threaded portion of the male screw portion 173. 故而,外层构件101的热亦会传递到外罩固定器104,且从此外罩固定器104的外周面散发到散热通路176。 Therefore, the heat will be transferred to the outer member 101 is fixed to the housing 104, and an outer peripheral surface of the housing from the fixture 104 for distributing the cooling passage 176. 因此,可利用外罩固定器104增加灯100的散热面积,且可进一步提高此发光元件127的冷却性能。 Thus, the housing holder 104 may be utilized to increase the area of ​​heat lamp 100, and may further improve the cooling performance of the light-emitting element 127.

如图21所示,如杲发光元件127的热在散热通路176上散发,则将会在散热通路176产生上升气流。 21, as the light emitting element 127 Gao heat on the heat distributing passage 176, 176 will generate the updraft cooling passage. 由此,灯IOO外部的空气则通过位于灯100 下端的吸气口178吸入散热通路176。 Thus, the external air through the lamp IOO 100 located in the lower end of the lamp cooling intake port passage 176,178. 吸入散热通3各176的空气,以从下到上的方式流经散热通路176后,从排气口i77排出到大气中。 3 through respective air suction heat 176, to the rear from the lower passage way 176 passing through the heat dissipation, is discharged from the exhaust port to the atmosphere i77.

外罩固定器104的外周面以及外层构件101的散热面112,是露出于散热通路176。 The fixed housing 104 and an outer circumferential surface of the outer member 101 of the heat dissipating surfaces 112, 176 is exposed to the cooling passage. 故而,传递到外罩固定器104以及外层构件101的发光元件127的热,将通过与流经散热通路176的空气进行热交换而散发。 Therefore, the heat transferred to the stationary housing member 104, and an outer layer 101 of the light emitting element 127 will be circulated through heat exchange with the air flowing through the cooling passage 176. 由此,可通过空气使外罩固定器104以及外层构件101冷却,且可抑制此发光元件127过热。 Accordingly, by air to the housing 104 and an outer holder member 101 is cooled, and the light-emitting element 127 is suppressed from overheating. 从而,可抑制发光元件127的发光效率下降,并且可延长发光元件127的寿命。 Thereby, possible to suppress the light emitting element 127 is lowered emission efficiency and extend the life of the light emitting element 127. 覆盖外罩固定器104以及外层构件101的隔热外罩108,是由导热性低 The housing cover 104 and an outer retainer member 108 of the insulation cover 101, by a low thermal conductivity

于外层构件101的合成树脂材料制造。 A synthetic resin material in the outer member 101 is manufactured. 因此,外罩固定器104及外层构件101的热将难以传递到隔热外罩1G8,且使隔热外罩108的溫度低于外层构件101。 Thus, the heat retainer 104 and an outer housing member 101 will be hardly transmitted to the insulation cover 1G8, and that the temperature of the insulation cover 108 than the outer member 101.

根据第7实施形态,拧入到隔热外罩108的连接构件168为合成树脂制成,因此连接构件168在外层构件101与隔热外罩108之间热绝缘。 According to the seventh embodiment, is screwed into the insulation cover 168 connecting member 108 is made of synthetic resin, the connection member 168 between the outer layer 101 and the insulation cover member 108 thermally insulated. 进而, 接触于外罩固定器104的隔热外罩108的扣合部175具有吸气口178。 Further engaging portion, in contact with the housing 104 of the fixture 108 of the insulation cover 175 has a suction port 178. 由此, 即使外罩固定器104的热传递到隔热外罩108的扣合部175,扣合部175也可通过从吸气口178流入散热通路176的空气而进行冷却。 Thus, the cover holder 104 even if the heat is transmitted to the insulation cover engagement portion 175, engaging portion 175 108 may also be cooled by the air 178 flows into the cooling passage 176 from the suction port. 从而,隔热外罩108将难以受到外罩固定器104的热影响,且可抑制隔热外罩108的温度上升。 Thus, the insulation cover 108 is difficult to be thermally affected by the fixed housing 104, and can suppress the temperature rise of the insulation cover 108.

根据第7实施形态的灯100,在例如灯100进行点灯时或者熄灯后立刻进行灯更换的情形时,操作者即使用手抓住隔热外罩108,也不会感觉到焚。 According to the seventh embodiment of the lamp 100, for example after the lamp 100 is turned on or light-off of the lamp replacement performed immediately case, the operator grasps the insulation cover 108, the hand will not feel even burning. 由此,不会产生操作者因为太烫而将使灯100掉落的顾虑,且可安全地进行灯100的更换作业。 Thus, the operator does not occur because of too hot and will fall concerns lamp 100, the lamp 100 and the replacement work can be safely.

图28以及图29揭示本发明第9实施形态。 28 and FIG. 29 discloses a ninth embodiment of the present invention. 第9实施形态是第8实施形态进"T步发展的情况,灯100的结构与第8 实施形态中的相同。由此,第9实施形态中对于与第8实施形态相同的结构部分付与相同参照符号,且省略其说明。 Ninth embodiment is a form feed "where T step of development, the structure of the eighth embodiment of the lamp 100 is the same as the eighth embodiment. Thus, the ninth embodiment attaches the same to the eighth embodiment of the same morphology moiety reference numerals, and description thereof is omitted.

第9实施形态中所述的灯100具有包围第1以及第2散热片200、 201 的外筒220。 In the ninth embodiment having the lamp 100 surrounds the first and second outer tube fins 220,200, 201. 外筒220形成直径大于外层构件101以及外罩固定器104的中空圆筒状。 Outer tube 220 is formed larger than the outer diameter of the hollow cylindrical member 101 and a cover 104 of the fixture. 外筒220具有从外层构件101的周壁110跨越外罩固定器104 的长度。 An outer tube 220 having a length in the circumferential wall 110 across the housing 104 from the outer fixed member 101. 外筒220的内周面与第1以及第2边缘外罩202 、 203相接。 An outer cylinder 220 and the inner circumferential surface of the first cover and the second edge 202, 203 in contact. 由此, 外筒220跨越相邻接的第1以及第2散热片200、 201之间。 Thus, the outer tube 220 across the adjacent first and second fins 200, 201.

换言之,外筒220夹持第1散热片200且与散热面112相对,并且夹持第2散热片201且与外罩固定器104的外周面相对。 In other words, the outer cylinder 220 of the first clamp 200 and the fin 112 and the heat dissipation opposing surface and the outer circumferential surface of the second gripping fins 201 and 104 fixed relative to the housing. 由此,在外层构件101的散热面112和外筒220之间、以及外罩固定器104的外周面和外筒220之间形成散热通路221。 Accordingly, the heat dissipation path 221 is formed between the outer surface of the heat dissipation member 101 and the outer cylinder 220 between 112, and the outer peripheral surface of the outer tubular housing and the fixture 104 220. 散热通路221在灯100的轴向上延续。 Continue cooling passage 221 in the axial direction of the lamp 100. 第l以及第2散热片200、 201露出于散热通路221。 L first and second fins 200, 201 are exposed to the cooling passage 221. 散热通路221具有一端221a 和另一端221b。 Cooling passage 221 has one end 221a and the other end 221b. 当以灯座107朝上的状态使灯100点灯时,散热通路221 的一端22la从第2散热片201的下端而在大气中开口。 When the socket 107 in a state facing upward lighting the lamp 100, one end of cooling passage 221 22la and the opening from the lower end of the second fin 201 in the air. 同样,当以灯座107 朝上的状态使灯100点灯时,散热通路221的另一端221b从第l散热片200 的上端在大气中开口。 Similarly, the socket 107 in a state when the lamp 100 is lit up, the cooling passage 221 from the upper opening of the other end 221b of the fins 200 l in the atmosphere.

外筒220是由导热性低于外层构件101以及外罩固定器104的材料制造。 Outer tube 220 is made of heat conductive material than the outer fixed member 101 and a cover 104. 较理想的是,例如,当使用热收缩性合成树脂材料形成外筒220时,将外筒220安装并固定在外层构件101以及外罩固定器104外侧之后,再加热外筒220并使其热收缩。 It is desirable that, for example, when using a heat-shrinkable synthetic resin material 220 formed in the outer cylinder, the outer cylinder 220 is mounted and secured after the outer layer 101 and a cover fixing member 104, the outer cylinder 220 was heated and allowed to heat shrinkage . 由此,外筒220的内周面将会被挤压到第1以及第2边缘外罩202、 203,且外筒220将会与外层构件101以及外罩固定器104结合为一体。 Accordingly, the inner circumferential surface of the outer tube 220 will be pressed into the first and second edges of the cover 202, 203, and 220 will be an outer cylinder and an outer member 101 and a cover 104 combined into one fixture. 从而,可易于进行外筒220的安装作业。 Thus, mounting work can be easily performed in the outer tube 220.

第9实施形态中所述的灯100中,若发光元件127的热被散发到散热通路221,则将会在散热通路221产生上升气流。 In the ninth embodiment, the lamp 100, the light emitting element 127 when the heat is radiated to cooling passages 221, 221 will generate the updraft cooling passage. 由此,灯100外部的空气将会被散热通路221的一端221a吸入。 Thereby, the external light 100 will be cooling air passage 221 one end 221a of the suction. 吸入到散热通路221中的空气,以由下而上的方式流经散热通路221之后,从散热通路221的另一端221b散发到大气中。 After cooling the intake air passage 221, flows through the bottom-up approach to cooling passages 221, 221 from the other end of the cooling passage 221b emitted to the atmosphere. . .

由此,传递到外罩固定器104以及外层构件101的发光元件127的热, 其通过与流经散热通路221的空气进行热交换而散发。 Thereby, the heat transferred to the stationary housing member 104, and an outer layer 127 of the light emitting element 101, which is circulated through the heat exchange with air flowing through the cooling passage 221. 由此,可通过空气而使具有第l散热片200的外层构件101、以及具有第2散热片201的外罩固定器104冷却,且可抑制发光元件127过热。 Thereby, the air passing through the outer member 101 having a first fin 200 l, and a housing 104 having cooling fins of the second holder 201, and the light emitting element 127 is suppressed from overheating. 从而,可抑制发光元件127 的发光效率下降,并可延长发光元件127的寿命。 Thereby, possible to suppress the light emitting element 127 is lowered emission efficiency and extend the lifetime of the light emitting element 127.

再者,外筒22G为合成树脂制,且其导热性低于外层构件101及外罩固定器104。 Furthermore, the outer cylinder 22G is made of synthetic resin, and its thermal conductivity than the outer fixed member 101 and the housing 104. 故而,外层构件101以及外罩固定器104的热将难以传递到外筒220,且可使外筒220的温度低于外层构件101及外罩固定器104。 Therefore, the outer member 101 and a heat fixing housing 104 will hardly transmitted to the outer tube 220, outer tube 220 and allows the temperature than the outer cover member 101 and the fixture 104.

结果是,在例如灯100进行点灯时或者熄灯后立刻更换灯时,即使操作者用手抓住外筒220,也不会感觉到烫。 As a result, when replacing the lamp immediately after the lamp 100 is turned on when, for example, lights or, even if the operator grasping the outer tube 220, will not feel hot. 由此,不会存在操作者因为太烫而使灯100掉落的顾虑,且可安全地更换灯IOO。 Thus, the presence of an operator is not too hot because the lamp 100 fall concerns, and can safely exchange the lamp IOO.

因此,熟习此项者会了解其他优势及修改,广义而言,本发明并不限定于此处所揭示及描述的具体例及代表例。 Thus, those skilled in the will appreciate other advantages and modifications, broadly speaking, the present invention is not limited to this particular embodiment disclosed and described herein, and representative examples. 所以,在不脱离所附加的权利要求及其相应者的宗旨或范围的情况下可以进行各种修改。 Therefore, in the case without departing from the spirit or scope of the appended claims and their respective ones can be variously modified.
