First embodiment

Fig. 4 is the stereogram according to the lighting device 1A of first embodiment, Fig. 5 is the stereogram of expression according to the cross section of the lighting device 1A of first embodiment, Fig. 6 is the sectional view according to the lighting device 1A of first embodiment, Fig. 7 is the exploded perspective view according to the lighting device 1A of first embodiment, Fig. 8 is the sectional view according to two housings 100 of the lighting device 1A of first embodiment, Fig. 9 is the stereogram that illuminating part 200 and reflecting plate 400 combine, and Figure 10 is the exploded perspective view of illuminating part 200 and reflecting plate 400.

With reference to Fig. 4 to Fig. 8, lighting device 1 comprises: two first single lighting module 10A; Two power control parts 20, the space 170 between two first single lighting module 10A; Carriage 30 combines two first single lighting module 10A, in addition, may further include side lid 40.With reference to Fig. 1, the first single lighting module 10A that uses in first embodiment comprises: housing 100; Illuminating part is contained in the housing 100; Diffuser plate 300 is spaced apart with illuminating part 200, can also comprise reflecting plate 400.

With reference to Fig. 4 to Fig. 8, in first embodiment, comprise two first single lighting module 10A, still, also can differently use two second single lighting module 10B to form first embodiment with it.Because the second single lighting module 10B has the first carriage joint portion 151 in the end of both sides shield 130, even so for the overall appearance that forms first embodiment two second single lighting module 10B are combined, outward appearance that combines with two first single lighting module 10A and function are compared does not have too big-difference yet.

With reference to Fig. 5 and Fig. 6, illuminating part 200 can be arranged on the base plate 110 of housing 100.Power control part 20 can be provided with in the shield 130 that is to be formed with among two the first single lighting module 10A the first carriage joint portion 151 and the coupled sidewall 120 formed spaces 170.At this moment, do not form the configuration of vertical direction because power control part 20 is layered in below the base plate 110, and on base plate 110 with the horizontal direction configuration, so the thickness of lighting device 1 will become thin than common lighting device.

At the ceiling of the building that the ceiling flush type illumination can be set, the ceiling of concrete body is arranged usually, on this ceiling, be provided with the works of M type bar or T type bar towards room base plate face, on this M type bar or T type bar, be attached with TEX plate etc.Usually the power control part 20 that is arranged on the vertical-type lighting device on the indoor ceiling of building is laminated in below the base plate 110 and is set up in vertical direction, so its thickness surpasses 70mm usually.But, dispose electric wire, air conditioning pipe etc. usually between the ceiling of concrete body and M type bar or the T type bar, so it is narrow that the space of lighting device can be set under a lot of situation.Therefore, be subjected to the restriction in space, common vertical-type lighting device imbedded ceiling and when being provided with, can cut off part M type bar and be provided with difficultly, perhaps helplessly its lighting position is arranged on the position that is not oneself to want to install.

Comparing with it, is about 45mm according to the lighting device 1A preferred thickness of first embodiment, thus narrow even the space is set, also can on ceiling, freely dispose lighting device, have easy advantage is set.Certainly, the size of so-called 45mm is and has the relative and example enumerated of lighting device now, thus can be according to the size of the thickness of power control part 20 and/or housing 100 etc., can change in a variety of forms according to the size of the lighting device 1A of first embodiment.

Lighting device 1 can have the rectangle of extending along first direction a, still, can be according to the position being set or environment is set of lighting device 1, the shape of its lighting device 1 can change in a variety of forms.

In order to make the light launched from illuminating part 200, tilt with the obtuse angle at the shield 130 of illuminating part 200 both sides face with respect to diffuser plate 300 with required luminous intensity distribution angular emission and in order to relax dazzle (glare).Can't determine the angle with diffuser plate 300 benchmark if do not comprise diffuser plate, then shield 130 can be by extending from the end of sidewall 120 and determining to the inclination of sidewall 120 outsides expansion.

The gradient of shield 130 can be various ways according to the design variations of lighting device 1.

With reference to Fig. 9 and Figure 10, illuminating part 200 can comprise LED210, load the substrate 220 of LED210, be configured in the heat release sheet 240 of substrate 220.In addition, substrate 220 can have and is used for the combined hole 230 that combines with housing 100.

In addition, lighting device may further include reflecting plate 400, and reflecting plate 400 is provided with around the inner face of the sidewall of housing 100, is used for emission is reflected towards the outside of lighting device 1 from the light of LED210.Reflecting plate 400 is not only around the inner face of sidewall 120, and the surface of the substrate 220 of preferred illuminating part 200 around the zone except disposing LED210.

Power control part 20 can comprise to lighting device 1 to be provided the power supply unit (PSU) (not shown) of power supply and illuminating part 200 is controlled and to its drive division that drives (not shown).

With reference to Fig. 5, diffuser plate 300 separates with illuminating part 200 on the direction that light irradiates from LED210 and disposes, emission realizes area sourceization from the light of the LED210 that is equivalent to each spot light by diffuser plate 300, makes the emission light of illuminating part 200 have uniform briliancy thus on the face of diffuser plate 300.

Illuminating part 200 is not formed on the front of lighting device 1, and is formed on the base plate 110 of housing 100.Therefore,, also compare, the interval between the LED210 is narrowed down, can reduce the use amount of substrate 220 with the situation that LED210 is configured in the LED210 of lighting device front even use under the situation of LED210 of equal number.

On the other hand, the light of launching from the LED210 as spot light forms area source by diffuser plate 300, need there be overlapping areas in the light of then launching from adjacent LED210 on the surface of diffuser plate 300, for this reason, LED210 and diffuser plate 300 need fully spaced apart.But, be greatly that the thickness that means lighting device 1 becomes big if spacing distance becomes, this is not preferred.In order to reduce spacing distance, need to reduce the distance between LED210.As mentioned above, illuminating part 200 is not formed on the front of lighting device 1, and is configured on the base plate 110 of housing 100, so the substrate 220 of illuminating part 200 also is defined on the width of the base plate 110 of housing 100.Its result, the interval that is configured in the LED210 on the substrate 220 also naturally and understandably diminishes, and also diminishes for forming required LED210 of area source and the interval between the diffuser plate 300.

Thus, owing to aforesaid structural advantage, can provide the lighting device 1 of elongated (slim).

In addition, if do not have under the state of diffuser plate 300, if emission is shone towards shadow surface from the light of each LED, then hot spot can take place.If the shape of light source self shines directly on the shadow surface, then light-struck zone does not have the zone of irradiation obviously to have any different with respect to light, and be called hot spot by light-struck zone this moment, with on every side form obvious limit than dark-part.Be under the situation of outdoor lightings such as common room lighting or street lamp if do not need centralized lighting, if hot spot takes place, then can reduce shadow surface all once, so not ideal.If use surface illuminator as embodiment, then compare the generation that can reduce hot spot with common some lighting device, so can make the Illumination Distribution of shadow surface even, there is the advantage that reduces eye fatigue.

With reference to Fig. 6 and Fig. 8.If single lighting module is with adjacent mode combination, then power control part 20 is disposed in the space 170 of being divided by shield 130 and sidewall 120 and forming, and second protuberance 22 that will be formed on the lower end of power control part 20 is inserted in the mode of sliding in the power control part engagement groove 152 at interface on the sidewall 120 that is formed at housing 100 and floor 110, and housing 100 and power control part 20 can firmly combine thus.

On the other hand, the development length that power control part engagement groove 152 extends along first direction a shown in Figure 7 and the length difference of housing 100 are few, but there is no need to take such shape, also can be the extremely short thin plate of development length with letter " C " or " 0 " shape.In addition, also can not form power control part engagement groove 152, but by in boring on the sidewall of housing 100 and in power control part 20, hole on the relative position of putting with the hole of sidewall 120, and utilize screw or locate and slightly housing 100 and power control part 20 are carried out combination.In addition, owing to power control part engagement groove 152 is formed on the housing 100 by extrusion molding, therefore help producing and slightly also can carrying out combination, therefore also can be described as the associated methods of plain mode housing 100 and power control part 20 even without additional screw or location.

The carriage joint portion has 153 two kinds of the first carriage joint portion 151 and the second carriage joint portions.On housing 100, can be formed with first, second 151,153, the first carriage joint portions 151, carriage joint portion and be connected with carriage 30, so that can firmly combine between the single lighting module with the second carriage joint portion 152.In addition, on housing 100, also can be formed with side lid engagement groove 154.Side lid engagement groove 154 be used for its with side lid 40 between combine, describe in other part for its combination.

The material of housing 100 can be metal material with good exothermic character or resin material etc.In addition, form aluminium or silver-colored oxide-film on the surface of housing 100, can guarantee mar proof, corrosion resistance and the durability of housing 100 thus, and can guarantee the good appearance of lighting device 1.

In addition, though shield 130 mainly is to cover dazzle on purposes, but except to the surface treatment on the surface of shield 130 to reflect well, reflection part is adhered to from the teeth outwards with the mode that prevents dazzle, also play the effect of reflecting plate, therefore can improve optical efficiency.

Housing 100 can the mode of assembling form by making behind base plate 110, sidewall 120, the shield 130 more respectively, also can form by the integrally formed mode that goes out whole housing 100, for example can form by the mode of extrusion molding.Integrally formed when going out housing 100, preferably not only integrally formedly go out base plate 110, sidewall 120, shield 130, diffuser plate engagement groove 180, first, second carriage joint portion 151,153, power control part engagement groove 152, side lid engagement groove 154 also can be integrally formed once.Housing 100 is alongst integrally formed in tall and thin mode on the whole.In addition, if go out housing 100 by modes such as extruding are integrally formed, then housing 100 vertical cross-section is in the longitudinal direction deleted in this direction and is had more identical shape.For example, the cross section of the mid portion of cut-out housing 100 is identical from the shape in the cross section of the nearer part of end face with cut-out.If integrally formedly go out housing 100, then can reduce the trouble of each parts of assembling, and reduce manufacturing process.

During shaping housing 100, the diffuser plate engagement groove 180 of above-mentioned explanation, first, second carriage joint portion 151,153, power control part engagement groove 152, side lid engagement groove 154 etc. might not be leaveed no choice but disposable shaping, and at least one parts can be integrally formed with it when shaping housing 100.For example, as required, can be shaped as the housing 100 that only is formed with base plate 110, sidewall 120, shield 130 and diffuser plate engagement groove 180, also can be shaped as the housing 100 that only is formed with base plate 110, sidewall 120, shield 130 and first, second carriage joint portion 151,153.

With reference to Fig. 8, diffuser plate engagement groove 180 can be formed on the interface of the medial surface of sidewall 120 and shield 130 upper surfaces.With reference to Figure 11 and Figure 12, comprise under the situation of the upper plate 140 that is used for replacing shield 130, the mid portion of the medial surface of sidewall 120 or with the medial surface of the approaching sidewall 120 of upper plate 140 on can be formed with diffuser plate engagement groove 120.

With reference to Fig. 8, on the lower surface of the lateral surface of the sidewall 120 of housing 100 or shield 130, can be formed with at least one in first, second carriage joint portion 151,153, power control part engagement groove 152, the side lid engagement groove 154.With reference to Figure 11 and Figure 12, comprise under the situation of the upper plate 140 that is used for replacing shield 130, be formed with in first, second carriage joint portion 151,153, power control part engagement groove 152, the side lid engagement groove 154 at least one at the lower surface of the lateral surface of the sidewall 120 of housing 100 or upper plate 140.

Owing to integrally formedly go out housing 100, therefore can transmit heat effectively and emit heat, so lighting device can have good exothermic character towards whole housing 100.Certainly, can replace shield 130 according to embodiment upper plate 140.

If describe in detail further, making each parts that constitute housing 100 respectively and carrying out under the situation of combination, can't realize complete face contact between the parts, but the contact of the point of part.Therefore therefore, the heat that is delivered to base plate 110 from illuminating part 200 can't be passed to sidewall 120 fully, and the hydrothermal solution of sidewall 120 can't be passed to shield 130 fully, can't be fully the parts of whole housing 100 be used as radiator body.In contrast to this, by extrusion molding under the integrally formed situation that goes out housing 100, because whole housing is parts, therefore the heat that produces self-luminescent part 200 or power control part 20 is evenly transmitted the process of arrival shield 130 through sidewall 120 from base plate 110, therefore has excellent exothermal effect.

Carry out supplemental instruction for exothermal effect.As described in the 5th embodiment, can form the optional feature that constitutes housing 100 in the lower end of outermost shield 130, therefore the surface area that the purpose that forms optional feature is to increase housing 100 can take to increase the surface area of housing 100 to improve the Any shape of exothermal effect to improve exothermal effect.Therefore optional feature can form closed surface with shield 130, sidewall 120, can also form louver when forming closed surface, and can form concavo-convex on shield 130 or sidewall 120 and play the effect of heat release pin.

Figure 39 is the sectional view with lighting module of another shape shield 130; Figure 40 is the sectional view with lighting module of another shape shield 130.With reference to Figure 39 and Figure 40, the cross section of shield 130 can be straight line, or multiple shape such as parabola or circular arc.But, the more important thing is that having which type of shield on earth limits angle θ compared with the shape of shield 130 self.

The lighting device that is formed with shield 130 has specific shield and limits angle θ, and therefore diffuser plate 300 can directly not enter in the visual field in this shield limits angle θ, is its main purpose owing to cover dazzle, and therefore having suitable shield, to limit angle θ extremely important.

Figure 41 is the key diagram that limits angle θ and shield angle α that covers according to the lighting device of embodiment.With reference to Figure 41, different with the shield 130 of Figure 41 is, for reduce dazzle make shield 130 according to sidewall 120 almost in line mode form, then shield limits that angle θ can reduce and shield angle α can increase, and this means in the angle that limits angle θ greater than shield not have dazzle.Therefore, as long as leave the fatigue that lighting device just can reduce the eyes that cause because of dazzle a little.

On the contrary, different with the shield 130 of Figure 41 is, if form shield 130 according to the mode that almost is parallel to sidewall 120, then shield limits that angle θ can increase and shield angle α can reduce, though meaning in the angle that limits angle θ greater than shield, this does not have dazzle, but,, also can produce dazzle and make eye fatigue even therefore far away again from lighting device because that shield limits angle θ is excessive.Yet,, therefore have the advantage that shadow surface is broadened because the range of scatter of light can fully broaden.

Thus, the lighting device of penetrating the field area around increase illumination need increase shield qualification angle θ, limits angle θ and need reduce shield around the lighting device that prevents dazzle.

Preferred shield limits angle θ and has value between 0 °～90 °, has value in the above-mentioned scope if shield limits angle θ, then is what can't see from the direct sunshine of described diffuser plate in the visual line of sight of another side from a side of diffuser plate 300.
