Light-emitting component 22 is LED, and is the LED encapsulation (package) of surface installing type.This LED encapsulation is the Zhou Fangxiang along a plurality of circular substrates 21, spreads all over multiple row and installs, and be to install spreading all over 3 row different roughly concentrically ringed week of radius in the present embodiment.That is, spread all over the row of the row of row, outer circumferential side of interior all sides and described interior all sides and outer circumferential side row the centre row and install.

The LED encapsulation comprises substantially: led chip (chip) is provided in the cavity (cavity) that is formed by pottery or synthetic resin; And epoxy is the translucent resin of mold (mold) usefulness of resin or silicone (silicone) resin etc., seals this led chip.

The LED that lists encapsulation for the row that are installed in interior all sides and outer circumferential side, use illuminant colour to be the LED encapsulation of bulb look (L) with color of sunshine (D), namely, use the LED encapsulation of so-called white, these LED encapsulation are to open roughly uniformly-spaced and alternately to arrange in concentrically ringed all sky roughly to set.Led chip is the led chip that sends blue light.In translucent resin, sneaked into fluorophor, light for the white color system that can go out lamp bulb look (L), color of sunshine (D), the main red-emitting phosphors that uses yellow fluorophor or be used for replenishing red composition, described yellow fluorophor radiate the light that has the yellow system of complementary color relation with blue light.In addition, described so-called white comprises color of sunshine (D), white in daytime (N), white (W) or bulb look (L) etc.

For the encapsulation of the LED that lists in the middle of being installed in, use the LED encapsulation of sending a plurality of illuminant colours, particularly, use the LED encapsulation of sending redness (R), green (G), blue (B) light.Therefore, led chip is the led chip of difference burn red, green light, blue light, and the translucent resin that these led chips are used by mold seals.

The LED encapsulation of rubescent look (R) light that lists in the middle of being installed in, green (G) light, blueness (B) light be on circumference roughly sequentially with the order of red (R), green (G), blue (B), sky is opened roughly uniformly-spaced and continuously configuration.For the LED encapsulation of these rubescent look (R) light, green (G) light, blueness (B) light, each illuminant colour uses identical quantity, and each plate base 21 of cutting apart is installed the LED encapsulation of 11 each illuminant colours.Therefore, use on the whole the LED encapsulation of each 44 each illuminant colour.

Specifically, as as adding shown in the reference of Fig. 7 and Fig. 8, for the LED encapsulation of different rubescent look (R) light of these illuminant colours, green (G) light, blueness (B) light, every kind of illuminant colour is multiple row (3 row) and is arranged in radius on different roughly concentrically ringed weeks, and staggers and configure in the position of the Zhou Fangxiang of the row that make these in each other.

A slice in the substrate 21 that Fig. 7 represents to cut apart, Fig. 8 represents the part of the Wiring pattern layer 12a of this substrate 21.And, in Fig. 8, in order to represent the position relationship of Wiring pattern layer 12a and light-emitting component 22, be represented by dotted lines the part of light-emitting component 22 in explanation.

As shown in Figure 7, for the LED encapsulation of rubescent look (R) light, green (G) light, blueness (B) light, every kind of illuminant colour is at radius on different roughly concentrically ringed weeks, that is, the LED of rubescent look (R) light is encapsulated on roughly concentrically ringed week that LED is encapsulated in radius r 2, the LED of the look that turns blue (B) light is encapsulated in radius r 3 of radius r 1, green-emitting (G) light respectively sky and opens roughly and uniformly-spaced configure.And, the LED encapsulation row of the row of the LED encapsulation of the row of the LED of these rubescent look (R) light encapsulation, green-emitting (G) light and the look that turns blue (B) light each other in light-emitting component 22 be to stagger (representing with d on the diagram) and be configured in the position that makes Zhou Fangxiang.

In addition, the LED encapsulation is roughly rectangular shape in shape, is provided with the electrode A e of anode (anode) side at a short brink, is provided with the electrode Ce of negative electrode (cathode) side at another short brink.In addition, in explanation, represent the minor face of the electrode Ce side of cathode side with thick line.

As shown in Figure 8, substrate 21 is to be laminated with Wiring pattern layer 21a on the surface with insulating properties, and then is laminated with reflecting layer 21b thereon and forms.And, on substrate 21, the LED encapsulation that a plurality of light-emitting components 22 are installed is surface installing type.

Wiring pattern layer 21a is formed with the pattern of Copper Foil by etching (etching), and forms in the lip-deep mode that spreads all over roughly whole ground covered substrate 21.Wiring pattern layer 21a is divided into a plurality of blocks (block) corresponding to the installation number of light-emitting component 22 by the insulating regions i of wire, and the electrode Ce of the electrode A e of the anode-side of light-emitting component 22 and cathode side stride across the relative narrower between block wire insulating regions i and connect.

Wiring pattern layer 21a is the electricity-led path to light-emitting component 22 supply capabilities, and has the function as radiating component (heat spreader), and described radiating component spreads the heat that produces from light-emitting component 22.Therefore, by guaranteeing large-area Wiring pattern layer 21a, can improve thermal diffusivity.

Reflecting layer 21b is that spreading all over roughly, whole ground forms except the part of the part that each light-emitting component 22 and connecting electrode Ae, Ce are installed and connection connector (connector) Cn.That is, the part of each light-emitting component 22 and connecting electrode Ae, Ce and the part of connection connector are installed becomes the state that Wiring pattern layer 21a exposes on the surface, to connect light-emitting component 22 and connector.

Particularly, reflecting layer 21b be use white photic welding resistance type (photo solder type) etching resisting ink (resist ink) material and form, be the resist layer of the good white of reflection of light rate.

Each light-emitting component 22 is to be divided between a plurality of blocks that form by the insulating regions i of wire, and the insulating regions i that strides across the wire of relative narrower is welded in Wiring pattern layer 21a with the electrode Ce of the electrode A e of the anode-side of light-emitting component 22 and cathode side and connects.

More specifically, the regional Sa of the Wiring pattern layer 21a side that connects compared with the electrode A e of the anode-side of light-emitting component 22, the area of the regional Sc of the Wiring pattern layer 21a side that the electrode Ce of cathode side connects forms greatlyr.That is, in the mode of the relation that becomes Sa＜Sc and form.

This kind light-emitting component 22 mainly produces heat at cathode side when luminous, the temperature of the electrode Ce of cathode side uprises.Therefore, the regional Sc of the Wiring pattern layer 21a side that connects by the electrode Ce that strengthens cathode side can utilize large tracts of land that the heat of generation is spread effectively and distributes, thereby the temperature that can suppress light-emitting component 22 rises.

Therefore, the illuminant colour that lists that is installed on interior all sides be bulb look (L) with the LED of color of sunshine (D) encapsulation in, alternately change electrode towards, the regional Sc of the Wiring pattern layer 21a side that is connected take the electrode Ce that guarantees cathode side for greatly.

On the other hand, be in the LED encapsulation of bulb look (L) and color of sunshine (D) at the illuminant colour that lists that is installed on outer circumferential side, the electrode Ce of cathode side is configured toward the outer side.Owing to existing the radiating effect in the outside than inboard high tendency, therefore the electrode Ce by making cathode side can expect the raising of thermal diffusivity toward the outer side.

Secondly, the LED of rubescent look (R) light that lists in the middle of being installed on, green (G) light, blueness (B) light encapsulates as mentioned above general configuration at radius on different roughly concentrically ringed weeks, and staggers and configure in the position of the Zhou Fangxiang of row in each other that makes at these.Therefore, when with illuminant colour be homochromy LED encapsulation when being connected in series as present embodiment, its connection can be simplified, particularly, the Wiring pattern layer 21a between connecting electrode can be simplified.

Suppose LED package arrangements with rubescent look (R) light, green (G) light, blueness (B) light on same circumference, then distribution is to avoid the LED encapsulation of adjacency agley, and it is intricate that the formation of Wiring pattern layer will become.

But, be disposed at radius on different roughly concentrically ringed weeks by as present embodiment, being staggered in the position of its all direction the LED of each illuminant colour encapsulation, thereby basically can on circumference, namely be the circular-arc homochromy LED encapsulation that connects (roughly linearity), therefore, can simplify its connection, and can make space (space) exist the zone of restriction to possess the enough and to spare of regulation, for example can simultaneously guarantee area as the Wiring pattern layer 21a of fin performance function for large, one side realizes connecting.

In addition, on the whole, the LED of each illuminant colour is encapsulated in the width that has regulation on the radial direction and arranges, and arranges in mode continuous on Zhou Fangxiang, so colour mixture is good and can improve uniformity.And, about radial direction, be the close configuration of LED encapsulation that becomes to the coloured light that turns white that lists of the row that are installed on interior all sides and outer circumferential side, therefore can expect the effect that becomes good with their mixed light.

And then, between the LED that the lists encapsulation of the LED of each illuminant colour encapsulation and the row that are installed on interior all sides and outer circumferential side, produce the zone of guaranteeing the space at radial direction, thereby can configure the part of connector Cn etc. effectively to apply flexibly the space at this area part.

In addition, as long as the regional Sc of the Wiring pattern layer 21a side that the regional Sa of the Wiring pattern layer 21a side that the electrode A e of the anode-side of light-emitting component 22 connects is connected with the electrode Ce of cathode side can become large mode and form with regional Sc, then its shape etc. is not particularly limited.

Fig. 9 represents the wiring state of each light-emitting component 22 on the plate base 21.Particularly, be installed on the row of interior all sides and the light-emitting component that lists 22 of outer circumferential side and comprise 2 lines (line), described 2 lines are that 4 series circuits are formed by connecting, and described 4 series circuits are 6 light-emitting components 22 to be connected in series form.Therefore, connecting at 1 line and adding up to 24 light-emitting components 22.And these series circuits are that to be divided into illuminant colour be that the light-emitting component group of bulb look (L) is connected with the light-emitting component group of color of sunshine (D).That is, in a series circuit, bulb look (L) can not mix existence with the light-emitting component 22 of color of sunshine (D).

On the other hand, the light-emitting component 22 of rubescent look (R) light that lists in the middle of being installed on, green (G) light, blueness (B) light is being connected in series 11 separately.And similarly, in these series circuits, the light-emitting component 22 of red (R), green (G), blue (B) can not mix existence.

The end of this kind connecting circuit is connected in connector Cn, in order to can be connected in the connector of substrate 21 of adjacency or the connector of mains side.

As mentioned above, in light source portion 2, configuring the different a plurality of light-emitting components 22 of illuminant colour, namely configuring the light-emitting component 22 of sending out bulb look (L) light, color of sunshine (D) light, redness (R) light, green (G) light, blueness (B) light, therefore by making these light-emitting component mixed lights, expressible photochromic scope is wide, by adjusting the light output of light-emitting component 22, can mix colours to photochromic.

That is, when development does not possess the lighting device of function of automatic control luminance, can easily omit optical sensor 6 and central component 4 and realize.

Adapter A as shown in Figure 6, by the hook that is located at upper surface side electrically and be connected mechanically to the part of the furred ceiling lamp holder body Cb that is arranged on the ceiling surface C, be roughly cylindric, and in the both sides of perisporium, to be provided with a pair of fastener A1 to the side-prominent mode of periphery all the time by built-in spring (spring).This fastener A1 submerges by the action bars (lever) that is located at lower face side is operated.And, from this adapter A derivation the not shown power line (cord) that is connected to described ignition device 3 is arranged, and be connected with ignition device 3 via connector.

Infra-red remote control transmitter Rc is the specific encoded infra-red remote control control signal of the pulse type of transmission frequency 38kHz for example, such as being provided with pattern (mode) switching push button (button), full luminous point button, light modulation point button, altar lamp button and light-off button etc.By being that infrared remote control signal acceptance division 102 operates towards auxiliary component unit 10 with this remote-controlled transmitter Rc, can control the illumination condition of light source portion 2 and indirect light light source portion 9.

Next, illustrate that with reference to Fig. 6 ligthing paraphernalia is installed on the installment state of ceiling surface C.At first, with adapter A electrically and be connected mechanically to the ceiling lamp holder main body Cb that sets in advance on ceiling surface C.Under the state of the cover member 8 of dismantling ligthing paraphernalia, make on the one hand the snap openings 51 alignment adapter A of adapter guide portion, overcome on the one hand elastic component 36 elastic force and from the below with pushing away on hand device body 1, until the fastener A1 of adapter A positively is sticked in till the snap openings 51 of adapter guide portion, thereby carry out fitting operation.

Next, mounting cup member 8 is with the opening 41 of the central portion of covering and obstruction and ceiling lamp holder main body Cb central component 4 in opposite directions.

And, in dismounting during ligthing paraphernalia, cover removal member 8, the opening 41 by central component 4 operates action bars set among the adapter A, with the engaging of the fastener A1 that removes adapter A, thus detachable.

Be installed at ligthing paraphernalia under the installment state of ceiling surface C, during to ignition device 3 supply capability, to light-emitting component 22 energisings, each light-emitting component 22 is lit a lamp via the substrate 21 in the light source portion 2.From the light transmission light source portion cover 25 of light-emitting component 22 towards the outgoing of front surface side, through lampshade 7 diffusions and through the irradiation of backward foreign side.Therefore, can the regulation the luminous intensity distribution scope in to below throw light on.

Meanwhile, during to indirect light light source portion 9 energising, each light-emitting component 92 is lit a lamp, and from light-emitting component 92 cover 93 of the light transmission light transmission of square outgoing obliquely, and mainly exposes to ceiling surface in the mode of radiation around adapter guide portion 5.Therefore, it is bright that ceiling surface becomes, and can improve the brightness impression in space.
