the first embodiment

Fig. 4 is according to the stereogram of the lighting device 1A of the first embodiment, Fig. 5 represents according to the stereogram in the cross section of the lighting device 1A of the first embodiment, Fig. 6 is according to the sectional view of the lighting device 1A of the first embodiment, Fig. 7 is according to the exploded perspective view of the lighting device 1A of the first embodiment, Fig. 8 is according to the sectional view of two housings 100 of the lighting device 1A of the 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 the first single lighting module 10A; Two power control parts 20, the space 170 between two the first single lighting module 10A; Bracket 30, combines two the first single lighting module 10A, in addition, may further include side lid 40.With reference to Fig. 1, the first single lighting module 10A using in the first embodiment comprises: housing 100; Illuminating part, is contained in 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, comprise two the first single lighting module 10A at the first embodiment, still, also can differently use two the second single lighting module 10B to form the first embodiment with it.Because the second single lighting module 10B has the first bracket joint portion 151 in the end of both sides shield 130, even so two the second single lighting module 10B are combined in order to form the overall appearance of the first embodiment, compared with the outward appearance combining with two the first single lighting module 10A and function also without big-difference too.

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 arrange and be to be formed with in two the first single lighting module 10A in the shield 130 of the first bracket joint portion 151 and space 170 that coupled sidewall 120 forms.Now, do not form the configuration of vertical direction below because power control part 20 is layered in base plate 110, and configure with horizontal direction on base plate 110, so the thickness of lighting device 1 will become thin than common lighting device.

The ceiling of building of ceiling flush type illumination can be set, conventionally have the ceiling of concrete body, on this ceiling, be provided with M type bar or T-shaped 's works towards room base plate face, on this M type bar or T-shaped, be attached with TEX plate etc.Conventionally the power control part 20 that is arranged on the vertical-type lighting device on the ceiling of Indoor environment is laminated in base plate 110 and is set up in vertical direction below, so its thickness exceedes 70mm conventionally.But, conventionally between the ceiling of concrete body and M type bar or T-shaped, dispose electric wire, air conditioning pipe etc., so it is narrow that the space of lighting device can be set in a lot of situation.Therefore, be subject to the restriction in space, common vertical-type lighting device imbedded to ceiling and while arranging, can cut off part M type bar and arrange difficultly, or helplessly its lighting position is arranged on the position that is not oneself to want to install.

In contrast, be about 45mm according to the lighting device 1A preferred thickness of the first embodiment, so narrow even if space is set, also can on ceiling, freely configure lighting device, have advantages of arrange easy.Certainly, the size of so-called 45mm is example relative with existing lighting device and that enumerate, so can, 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 the first embodiment.

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

For the light that makes to launch from illuminating part 200 is launched with required light distribution angle and in order to relax dazzle (glare), tilts with respect to the face of diffuser plate 300 at the shield 130 of illuminating part 200 both sides with obtuse angle.Cannot determine the angle with diffuser plate 300 benchmark if do not comprise diffuser plate, shield 130 can be extended and be determined to the inclination of sidewall 120 outside expansions by the end from sidewall 120.

With reference to Fig. 5, the direction that diffuser plate 300 irradiates from LED210 at light, separate with illuminating part 200 and configure, transmitting realizes area source from the light of the LED210 that is equivalent to each spot light by diffuser plate 300, makes thus the utilizing emitted light of illuminating part 200 on the face of diffuser plate 300, have uniform briliancy.

Illuminating part 200 be not formed on lighting device 1 before, and be formed on the base plate 110 of housing 100.Therefore, even if use in the situation of LED210 of equal number, compared with the situation of the LED210 before being also configured in lighting device with LED210, can make the interval between LED210 narrow, can reduce the use amount of substrate 220.

On the other hand, pass through diffuser plate 300 forming surface light sources from the light of launching as the LED210 of spot light, launch from the light of adjacent LED210 and need on the surface of diffuser plate 300, have overlapping region, for this reason, LED210 and diffuser plate 300 need fully spaced apart.But, be greatly that the thickness that means lighting device 1 becomes large 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 be not formed on lighting device 1 before, and be configured on the base plate 110 of housing 100, so the substrate 220 of illuminating part 200 is also defined on the width of the base plate 110 of housing 100.Its result, the interval that is configured in the LED210 on substrate 220 also naturally and understandably diminishes, and also diminishes for the interval between required LED210 and the diffuser plate 300 of forming surface light source.

Thus, due to structural advantage as above, can provide the lighting device 1 of elongated (slim).

In addition, if do not had under the state of diffuser plate 300, if transmitting is irradiated towards shadow surface from the light of each LED, can there is hot spot.If the shape of light source self shines directly on shadow surface, obviously have any different in the region that light-struck region is not irradiated with respect to light, and the region being now irradiated by light is called hot spot, with around form obvious boundary compared with dark-part.Be in the situation of the outdoor lightings such as common room lighting or street lamp if do not need centralized lighting, if occur hot spot, can reduce shadow surface all once, so not ideal.If as embodiment uses surface illuminator, can reduce the generation of hot spot compared with common some lighting device, so can make the Illumination Distribution of shadow surface even, there is the advantage that reduces eye fatigue.

< housing 100>

The structure of housing 100 is illustrated in the first embodiment to the six embodiment, therefore omits the explanation to this part.

With reference to Fig. 6 and Fig. 8.If single lighting module is with adjacent mode combination, power control part 20 is disposed in the space 170 of being divided by shield 130 and sidewall 120 and form, and the second protuberance 22 of the lower end that is formed on power control part 20 is inserted in the power control part engagement groove 152 that is formed at the sidewall 120 of housing 100 and the interface on floor 110 in the mode of sliding, 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 the first direction a shown in Fig. 7 and the length difference of housing 100 are few, but there is no need to take such shape, also can there is for development length is extremely short the thin plate of letter " C " or " 0 " shape.In addition, also can not form power control part engagement groove 152, but by boring on the sidewall at housing 100 and hole with on the relative position of putting, hole of sidewall 120 in power control part 20, and utilize screw or locate and slightly housing 100 and power control part 20 are carried out to combination.In addition, owing to by extrusion molding, power control part engagement groove 152 being formed on housing 100, therefore be conducive to produce and slightly also can carry out combination to housing 100 and power control part 20 even without additional screw or location, therefore also can be described as the associated methods of plain mode.

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

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

In addition, although shield 130 is mainly to cover dazzle in purposes, but except to the surperficial surface treatment of shield 130 reflecting well, reflection part is adhered to from the teeth outwards to prevent, the mode of dazzle, also playing the effect of reflecting plate, therefore can improve optical efficiency.

Housing 100 can form by manufacturing respectively after base plate 110, sidewall 120, shield 130 mode of assembling again, also can by integrally formed go out the mode of whole housing 100 form, for example can form by the mode of extrusion molding.Integrally formed go out when housing 100, preferably not only integrally formed go out base plate 110, sidewall 120, shield 130, diffuser plate engagement groove 180, first, second bracket 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 by the modes such as extruding integrally formed go out housing 100, housing 100 vertical cross-section is in the longitudinal direction deleted and is had more identical shape in this direction.For example, cut off the cross section of mid portion of housing 100 identical with the shape in cut-out cross section of the part close to from end face.If integrally formed go out housing 100, can reduce assembling all parts trouble, and reduce manufacturing process.

When Shaped shell 100, the diffuser plate engagement groove 180 of above-mentioned explanation, first, second bracket 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 in the time of Shaped shell 100.For example, as required, can be shaped as the housing 100 that is only formed with base plate 110, sidewall 120, shield 130 and diffuser plate engagement groove 180, also can be shaped as the housing 100 that is only formed with base plate 110, sidewall 120, shield 130 and first, second bracket joint portion 151,153.

With reference to Fig. 8, diffuser plate engagement groove 180 can be formed on the medial surface of sidewall 120 and the interface of shield 130 upper surfaces.With reference to Figure 11 and Figure 12, comprise in the situation of the upper plate 140 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 lateral surface of sidewall 120 of housing 100 or the lower surface of shield 130, can be formed with at least one in first, second bracket joint portion 151,153, power control part engagement groove 152, side lid engagement groove 154.With reference to Figure 11 and Figure 12, comprise in the situation of the upper plate 140 for replacing shield 130, be formed with at least one in first, second bracket joint portion 151,153, power control part engagement groove 152, side lid engagement groove 154 at the lateral surface of sidewall 120 of housing 100 or the lower surface of upper plate 140.

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

If described in detail further, form all parts of housing 100 and carry out combination in the case of manufacturing respectively, between parts, cannot realize complete face contact, but the contact of the point of part.Therefore, the heat that is delivered to base plate 110 from illuminating part 200 cannot be passed to sidewall 120 fully, and the hydrothermal solution of sidewall 120 cannot be passed to shield 130 fully, therefore cannot fully the parts of whole housing 100 be used as radiator body.In contrast to this, by extrusion molding integrally formed go out in the situation of 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 additional information for exothermal effect.As described in the 5th embodiment, can form the optional feature that forms housing 100 in the lower end of outermost shield 130, the object that forms optional feature is that the surface area that increases housing 100 is to improve exothermal effect, therefore can take the surface area that can increase housing 100 to improve any shape of exothermal effect.Therefore optional feature can form closed surface together with shield 130, sidewall 120, can also form louver forming in closed surface, and can on shield 130 or sidewall 120, form concavo-convex and play the effect of heat release pin.

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

The lighting device that is formed with shield 130 has specific shield and limits angle θ, and therefore in this shield limits angle θ, diffuser plate 300 can directly not enter in the visual field, is its main purpose owing to covering dazzle, therefore has suitable shield restriction 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 from the shield 130 of Figure 41 is, for reduce dazzle make shield 130 according to sidewall 120 almost mode in line form, shield limits that angle θ can reduce and shield angle α can increase, and this means in the angle that is greater than shield and limits angle θ and does not have dazzle.Therefore, as long as leave a little lighting device and just can reduce the fatigue of the eyes that cause because of dazzle.

On the contrary, different from the shield 130 of Figure 41 is, if form shield 130 according to the mode that is almost parallel to sidewall 120, shield limits angle θ can increase and shield angle α can reduce, although meaning in the angle that is greater than shield restriction angle θ, this there is not dazzle, but to limit angle θ excessive due to shield, though therefore from lighting device again away from, also can produce dazzle and make eye fatigue.But, because the range of scatter of light can fully broaden, therefore have advantages of that the shadow surface of making broadens.

Thus, need increase shield around the lighting device that increases irradiation field area and limit angle θ, limit angle θ and need reduce shield around the lighting device that prevents dazzle.

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

On the base plate 110 of housing 100, must dispose illuminating part 200, therefore base plate 100 has width and the length that can configure illuminating part 20, on the position that sidewall 120 and shield 130 contact, can form diffuser plate engagement groove 180, in diffuser plate engagement groove 180, can accompany the fixed projection 430 of diffuser plate 300 and/or reflecting plate 400.Diffuser plate engagement groove 180 can be the shape of extending along first direction a shown in Fig. 7, Figure 13 and Figure 19.

In diffuser plate engagement groove 180, insert the fixed projection 430 of diffuser plate 300 and/or reflecting plate 400 in the mode of sliding, if at least one end of housing 100 in conjunction with side lid 40, diffuser plate 300 and/or reflecting plate 400 are fully firmly fixed.Therefore, arrange after lighting device, no matter be in use or in transit, can not worry that diffuser plate 300 and/or reflecting plate 400 are separated from lighting device.

In Fig. 1 to Fig. 3, the sidewall 120 of housing 100 and base plate 110 are vertical direction and extend, but and do not require must be vertical, in fact with subvertical mode extend also cannot, and also can form according to the mode of launching more outward to tilt away from more from base plate 110.

In addition, although not shown, be formed with concavo-convexly at the lower surface of housing 100, therefore make the surface area of above-mentioned housing 100 increase, can improve the exothermic character of lighting device.
