Particularly, if the area with respect to substrate 110, the shared ratio of contact area of support unit 180 and substrate 110 is more than 5%, can will be the substrate 110 of bending state, to exist the state of the part not contacting with support unit 180 to be installed to support unit 180.

Accordingly, the heat occurring for LED module 129, can maintain the radiating effect of the regulation of being undertaken by support unit 180, and, for example can improve the second interarea 110b towards the free degree.That is, can make the second interarea 110b towards becoming, for example than the state shown in Figure 11 toward the outer side and towards inner side.

Therefore the bulb-shaped lamp 1 that, possesses LED module 129 is the illumination light source with good light distribution characteristic.

[light distribution characteristic]

Then, utilize the mode of relatively giving an example to describe the light distribution characteristic of the related illumination light source of the utility model.Figure 12 is the front elevation of the bulb-shaped lamp 200 of example as a comparison.

Bulb-shaped lamp 200 shown in Figure 12 possesses: enclosed globe shade 210, LED module 220 and at the support unit 240 of enclosed globe shade 210 internal support LED modules 220.

LED module 220 has substrate 221 and four light-emitting components 222.Light-emitting component 222 is identical with above-mentioned light-emitting component 22, is SMD type LED element.And four light-emitting components 222 are configured in the interarea 221a of substrate 221, the back side 221b of substrate 221 does not configure light-emitting component 222.Figure 13 is the distribution curve flux figure that the light distribution characteristic of the bulb-shaped lamp 200 shown in Figure 12 is shown.

Distribution curve flux shown in Figure 13 illustrates for the size of luminosity of all directions of 360 ° that comprises the above-below direction of bulb-shaped lamp 200.In this distribution curve flux figure, the direction of the upper side of the lamp axle J of the bulb-shaped lamp in Figure 12 200 is made as to 0 °, along the direction of lamp axle J lower side, be made as 180 ° (180 °), at the scale interval clockwise and counterclockwise, be 10 °.

Scale in the footpath direction of distribution curve flux figure (0 to 100cd (candela)) represents luminosity.

At this, " luminous intensity distribution angle " represents, the size of the angular range that the luminosity peaked over half of the luminosity in illumination light source penetrates.That is, in the distribution curve flux figure shown in Figure 13, the angular range size at luminous intensity distribution angle is, more than 50% (more than about 30cd) of the maximum of luminosity (about 60cd).

Particularly, in the distribution curve flux shown in Figure 13, the shown light distribution characteristic in luminous intensity distribution angle is, the central shaft of bulb-shaped lamp 200 of take is benchmark, the scope of approximately-40 ° to approximately+40 °.That is, the luminous intensity distribution angle of bulb-shaped lamp 200 is approximately 80 °.And, by the related illumination light source of the utility model, can realize larger luminous intensity distribution angle.

As an example of the light distribution characteristic of the related illumination light source of the utility model, show the light distribution characteristic of the bulb-shaped lamp 1 that possesses the related LED module of above-mentioned variation 1 120.

Figure 14 is the distribution curve flux figure that the light distribution characteristic of the bulb-shaped lamp 1 that possesses the related LED module of variation 1 120 is shown.

Distribution curve flux figure shown in Figure 14 represents, for the size of luminosity of all directions of 360 ° that comprises the above-below direction of bulb-shaped lamp 1.In this distribution curve flux figure, the direction of upper side (with reference to Fig. 1) of lamp axle J along possessing the bulb-shaped lamp 1 of LED module 120 is made as to 0 °, along the direction of lamp axle J lower side, is made as 180 ° (180 °), is 10 ° at the scale interval clockwise and counterclockwise.

Scale in the footpath direction of distribution curve flux figure (0 to 50cd (candela)) represents luminosity.

That is,, in the distribution curve flux figure shown in Figure 14, luminosity is that more than 50% size of the angular range of (more than about 25cd) of maximum (about 50cd) is the luminous intensity distribution angle of bulb-shaped lamp 1.

Particularly, in the distribution curve flux figure shown in Figure 14, the shown light distribution characteristic in luminous intensity distribution angle is, the central shaft of bulb-shaped lamp 1 of take is benchmark, the scope of approximately-150 ° to approximately+150 °.That is the luminous intensity distribution angle that, possesses the bulb-shaped lamp 1 of LED module 120 is approximately 300 °.

Like this, by the related illumination light source of the utility model (bulb-shaped lamp 1), illumination light source (for example, the bulb-shaped lamp 200 shown in Figure 12) compared with only possessing a plurality of light-emitting components facing one direction, can access large luminous intensity distribution angle.

[radiating effect of support unit]

Then, the radiating effect of the related support unit of the utility model is described.Figure 15 shows the area with respect to substrate, the shared ratio (hereinafter referred to as " contact area rate ") of the contact area of support unit and substrate, with the relation of the temperature of light-emitting component.

Particularly, the chart shown in Figure 15 shows, in the related LED module 122 of above-mentioned variation 3, and the relation of the junction temperature of contact area rate and light-emitting component 22 temperature of junction surface substrate 27 (light-emitting component 22 with).

As shown in Figure 15, along with the increase of contact area rate, the junction temperature of light-emitting component 22 reduces.This be because, when the area change of the end face 175 (with reference to Fig. 6 (a) and Fig. 6 (b)) of the support unit 170 contact with substrate 21, the cause of the amount of thermal conduction increase of the time per unit from substrate 27 to support unit 170.

And, known when inquiring into the chart shown in Figure 15 in detail, along with the increase of contact area rate, the reduced rate of the junction temperature of light-emitting component 22 decline (the negative inclination of chart diminishes).That is,, along with the increase of contact area rate, the effect that the temperature of the light-emitting component 22 causing because of the increase of contact area rate reduces diminishes.

Invention personnel of the present utility model notice the variation of junction temperature of this light-emitting component 22 and the variation of the reduced rate of junction temperature, and the conclusion drawing is that contact area rate is preferably in more than 5%.Particularly, as the following description.

In the drive circuit 80 possessing at bulb-shaped lamp 1, there are various electronic units, for example, as this parts that need to avoid hot environment of electrolytic capacitor.

And, as the light-emitting component 22 of SMD type LED element as previously discussed, there is the seal member 22c comprising for the fluorophor particle of wavelength conversion.The efficiency of being carried out wavelength conversion by this fluorophor particle can reduce under the environment of high temperature, for seal member 22c, is also same, and it is important not becoming as much as possible high temperature.

Therefore, the quality of considering electronic unit maintain and the situation such as maintain of light wavelength conversion efficiency under, the junction temperature of light-emitting component 22 is for example preferably lower than 120 ℃.

In addition, the increase of contact area rate can cause the minimizing in the region that can configure light-emitting component 22 at the back side of substrate (can installation region).That is, routine LED module 20 described above and 120 to 122, considering to possess in the situation that all configure the two-sided installation base plate of more than one light-emitting component 22 on interarea and the back side, has the situation that can not make contact area rate become excessive.

Therefore, invention personnel of the present utility model, for 120 ℃ of the upper limits of the junction temperature of light-emitting component 22, consider and reserve 10 ℃ of above leeway, and in order to obtain than 120 ℃ low 10 ℃ above values, thereby the conclusion drawing is that the preferred lower limit value of contact area rate is 5%.

; the formation adopting in each of above-mentioned embodiment 1 and each variation is; the area of the substrate having with respect to LED module, the shared ratio (contact area rate) of contact area of support unit and substrate is more than 5% (0.05).

Consequently, can either make a plurality of light-emitting components 22 with this LED module realize large luminous intensity distribution angle, can suppress again the reduction of the luminous efficiency that causes because of heat that the plurality of light-emitting component 22 produces when luminous.

And, such as in the situation that the two-sided installation base plates such as substrate 21 shown in Fig. 1, according to number and the position of light-emitting component 22 (or 23) that should be installed to the back side of substrate, carry out the upper limit of regulation contact area rate.

For example, as shown in FIG. 1, in the situation that two light-emitting components 22 of the back side 21b of substrate 21 configuration, with each of this two light-emitting components 22, do not contact the scope of support unit 40, carry out the upper limit of regulation contact area rate.

That is, the value of the upper limit of contact area rate is, is compared to the 5% (0.05) large of lower limit, and, be the value corresponding with being installed to the number of light-emitting component at the back side of substrate and position.

And the lower limit of contact area rate can be also for example to make the junction temperature of light-emitting component 22 become 10% below 100 degree.That is to say, more preferred contact area rate is more than 10%.

And the lower limit of contact area rate can be also, for example can make the junction temperature of light-emitting component 22 further reduce, and the effect that the temperature of light-emitting component 22 reduces along with the increase of contact area rate reduce gradually 25%.That is to say, the contact area rate being more preferably is more than 25%.

And, contact area rate can be for more than 5%, also can be preferably more than 10%, but also can be more preferably 25%, for this feature of contact area rate, not only go for the related bulb-shaped lamp of embodiment 11, and go for bulb-shaped lamp related in variation 1 to 81.
