Here, the heat transmission conductor 34 for covering a part of 35 flange 352 and the 1st face 301 of circuit substrate 30 contacts (ginseng
According to Fig. 7).That is, cover 35 and 34 thermal of heat transmission conductor.Therefore, what heating part 33 was issued is hot from circuit substrate
30 conduct via heat transmission conductor 34 to cover 35, shed from cover 35 into atmosphere.So being dissipated in power supply device 3 with not having
Heat is compared with conductor 34 with the case where cover 35 (radiating component), and the heat that heating part 33 can be promoted to be issued sheds.As a result,
It is possible to realize the thermal diffusivities for improving the heat that heating part 33 is issued for power supply device 3.In addition, in power supply device 3, due to cover 35
Flange 352 and 34 thermal of heat transmission conductor, therefore can between cover 35 and heat transmission conductor 34 efficiently conduction heat.
In addition, cover 35 covers the 1st part 31 on the 1st face 301 of circuit substrate 30 in power supply device 3, so as to
The 1st part 31 is protected using cover 35.
In lighting unit 2, since LED20 to be installed on to the circuit substrate 30 of power supply device 3, LED20 is not needed
Dedicated substrate can cut down parts count.In addition, the ratio in the 1st face 301 of circuit substrate 30 is installed in lighting unit 2
There is the 1st region 303 of the 1st part 31 that LED20 is installed close to the 2nd region 304 of the periphery of circuit substrate 30.As a result, lighting

Through hole 309 is nearby (referring to Fig. 4).Therefore, the heat that heating part 33 is issued is transferred to installation spiral shell by heat transmission conductor 34
Nail 22, rises the temperature of mounting screw 22.In the case where the temperature of mounting screw 22 excessively rises, with mounting screw 22
The temperature of the light distributing cap 21 of contact also can excessively rise, and may make the convex edge 210 of plastic light distributing cap 21 is equal to become
Shape.Thus, in the lighting unit 2 with light distributing cap 21, preferably, reduces from heat transmission conductor 34 to mounting screw 22 and transmit
Heat amount, excessively increase the temperature of light distributing cap 21.Then, heat transmission conductor 34 is formed as the 1st of circuit substrate 30
On face 301, make from the part Chong Die with heating part 33 of heat transmission conductor 34 to heat transmission conductor 34 near installation spiral shell
The distance X1 along heat transmission conductor 34 of the part of nail 22 (referring to Fig. 4) longer than shortest distance X0.Wherein, shortest distance X0 is
The shortest distance of the part Chong Die with heating part 33 slave heat transmission conductor 34 on 1st face 301 to mounting screw 22.Specifically
For, in heat transmission conductor 34, from the thickness direction (up and down direction) of circuit substrate 30, in 33 (diode of heating part
Electric bridge 42) and it is formed between the through hole 309 away from the nearest position of heating part 33 part (the slot there is no conductor
340).That is, the heat that diode bridge 42 is issued is conducted around slot 340 to the position for being located most closely to through hole 309
The end for the heat transmission conductor 34 set, therefore compared with the case where slot 340 are not present, it can reduce from heat transmission conductor 34 to peace
The amount for the heat that cartridge screw 22 transmits.As a result, lighting unit 2 is able to suppress the excessive rising by the temperature of mounting screw 22 and causes
Light distributing cap 21 deformation etc..In addition, heat transmission conductor 34 can also form 1 or more hole to substitute slot 340.In addition, excellent
Choosing is the heat resisting temperature etc. of the heat issued according to heating part 33 and the material for forming light distributing cap 21, by the length of slot 340
Degree, width and the number in hole are set as optimal length, width and number.
In addition, cover 35 has for reflecting the reflecting surface 3500 from the LED20 light radiated (referring to Fig. 2 and Fig. 6).Reflecting surface
3500 be the surface (outer surface) of the incorporating section 350 of cover 35.Wherein, preferably, in the incorporating section 350 as reflecting surface 3500
Surface is coated with the coating of white color system.In lighting unit 2, the light radiated from LED20 is reflected using the reflecting surface 3500 of cover 35,
Therefore it is possible to realize the utilization efficiency improved from the LED20 light radiated.
