first embodiment

Fig. 4 is the stereogram of the lighting device 1A according to the first embodiment, Fig. 5 represents the stereogram according to the cross section of the lighting device 1A of the first embodiment, Fig. 6 is the sectional view of the lighting device 1A according to the first embodiment, Fig. 7 is the exploded perspective view of the lighting device 1A according to the first embodiment, Fig. 8 is the sectional view of two housings 100 of lighting device 1A according to 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, makes two the first single lighting module 10A combine, in addition, may further include side lid 40.With reference to Fig. 1, the use in a first embodiment first single lighting module 10A 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 in a first embodiment, but, also two the second single lighting module 10B differently can be used 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 if so two the second single lighting module 10B are combined in order to the overall appearance forming the first embodiment, also without too big-difference compared with the outward appearance combined with two the first single lighting module 10A and function.

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

The ceiling of the building that ceiling flush type throws light on can be arranged, usually there is the ceiling of concrete body, this ceiling is provided with towards room base surface the works of M type bar or T-shaped bar, this M type bar or T-shaped bar are attached with TEX plate etc.Usually the power control part 20 being 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, so its thickness is usually more than 70mm below.But, be configured with electric wire, air conditioning pipe etc. between the ceiling of usual concrete body and M type bar or T-shaped bar, so the space that can arrange lighting device in a lot of situation is narrow.Therefore, by the restriction in space, when common vertical-type lighting device being imbedded ceiling and arranges, part M type bar can be cut off and struggle with arrange, or helplessly its lighting position is arranged on be not oneself want install position on.

In contrast, the lighting device 1A preferred thickness according to the first embodiment is about 45mm, even if so installation space is narrow, also freely can configure lighting device on the ceiling, have and arrange easy advantage.Certainly, the size of so-called 45mm is relative with existing lighting device and example that is that enumerate, so can according to the size of the thickness of power control part 20 and/or housing 100 etc., the size according to the lighting device 1A of the first embodiment can change in a variety of forms.

Lighting device 1 can have the rectangle extended along first direction a, but according to the setting position of lighting device 1 or can arrange environment, the shape of its lighting device 1 can change in a variety of forms.

To launch with required light distribution angle to make the light launched from illuminating part 200 and in order to relax dazzle (glare), tilt with obtuse angle relative to the face of diffuser plate 300 at the shield 130 of illuminating part 200 both sides.If do not comprise diffuser plate and cannot determine with the angle of diffuser plate 300 benchmark, then shield 130 can be determined in the inclination by extending from the end of sidewall 120 to sidewall 120 outer expandable.

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, loads the substrate 220 of LED210, be configured in the heat release sheet 240 of substrate 220.In addition, substrate 220 can have the combined hole 230 for combining with housing 100.

In addition, lighting device may further include reflecting plate 400, reflecting plate 400 around the sidewall of housing 100 inner face and arrange, be used for by transmitting reflect 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 preferred surface around the substrate 220 of the illuminating part 200 in the region except being configured with LED210.

Power control part 20 can comprise to be provided the power supply unit of power supply (PSU) (not shown) to lighting device 1 and controls illuminating part 200 and the drive division (not shown) driven it.

With reference to Fig. 5, diffuser plate 300 separates with illuminating part 200 at light and configures from the direction that LED210 irradiates, launch and realize area source from the light of the LED210 being equivalent to each spot light by diffuser plate 300, make the utilizing emitted light of illuminating part 200 on the face of diffuser plate 300, have uniform briliancy thus.

Illuminating part 200 is not formed in before lighting device 1, and is formed on the base plate 110 of housing 100.Therefore, even if when using the LED210 of equal number, compared with the situation being also configured in the LED210 before lighting device with LED210, the narrower intervals between LED210 can be made, the use amount of substrate 220 can be reduced.

On the other hand, the light launched from the LED210 as spot light is by diffuser plate 300 forming surface light source, then launch and need on the surface of diffuser plate 300, there is overlapping region from the light of adjacent LED210, for this reason, LED210 and diffuser plate 300 need fully spaced apart.But if it is greatly mean that the thickness of lighting device 1 becomes large that 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 in before lighting device 1, and is 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 being configured in the LED210 on substrate 220 also naturally diminishes, and LED210 needed for forming surface light source and the interval between diffuser plate 300 also diminish.

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

In addition, if under the state not having diffuser plate 300, irradiate towards shadow surface from the light of each LED if launched, then hot spot can occur.If the shape of light source self shines directly on shadow surface, then obviously have any different in the region that light-struck region is not irradiated relative to light, the region be now irradiated by light is called hot spot, to form obvious boundary with the comparatively dark-part of surrounding.If when not needing centralized lighting and be the outdoor lighting such as common room lighting or street lamp, if there is hot spot, then the uniformity of shadow surface can be reduced, so not ideal.If as embodiment uses surface illuminator, then the generation of hot spot can be reduced compared with common some lighting device, so the Illumination Distribution of shadow surface can be made even, there is the advantage reducing eye fatigue.

Below, be described around inscape illumination apparatus 1.

< housing 100>

The structure of housing 100 is illustrated in the first embodiment to the 6th embodiment, therefore omits the explanation to this part.

With reference to Fig. 6 and Fig. 8.If single lighting module combines in adjacent mode, then power control part 20 is configured in the space 170 that divided and formed by shield 130 and sidewall 120, and the second protuberance 22 being formed in the lower end of power control part 20 is inserted in a sliding manner be formed at the sidewall 120 of housing 100 and the interface on floor 110 power control part engagement groove 152 in, 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 few, but there is no need to take such shape, also can for development length is extremely short and have the thin plate of letter " C " or " 0 " shape.In addition, also power control part engagement groove 152 can not be formed, but be relative with the hole of sidewall 120 and hole in the position of putting by boring on the sidewall of housing 100 and in power control part 20, and utilize screw or locate and slightly housing 100 and power control part 20 are combined.In addition, due to molding by extrusion, power control part engagement groove 152 is formed on housing 100, therefore be conducive to producing and slightly also can combine 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 the first bracket joint portion 151 and 153 two kinds, the second bracket joint portion.Housing 100 can be formed first, second bracket joint portion 151, bracket joint portion 151,153, first be connected with bracket 30 with the second bracket joint portion 152, to make can firmly combine between single lighting module.In addition, 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, is described in other part for its combination.

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

In addition, although shield 130 mainly covers dazzle in purposes, but except the surface treatment on the surface to shield 130 to be attached to reflect well, by reflection part on the surface with except the mode preventing dazzle, also play the effect of reflecting plate, therefore, it is possible to improve light efficiency rate.

Housing 100 can by manufacturing base plate 110 respectively, sidewall 120, the mode of assembling again after shield 130 formed, also can by integrally formed go out the mode of whole housing 100 formed, such as, mode by extrusion molding is formed.Integrally formed go out housing 100 time, 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.The mode of housing 100 on the whole alongst with tall and thin is integrally formed.In addition, if by the mode such as extruding integrally formed go out housing 100, then housing 100 vertical cross-section is in the longitudinal direction deleted in this direction and is had more identical shape.Such as, the cross section cutting off the mid portion of housing 100 is identical from the shape in the cross section of the part close to end face with cut-out.If integrally formed go out housing 100, then can reduce assembling all parts trouble, and reduce manufacturing process.

During 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 disposablely be shaped, at least one parts can be integrally formed with it when Shaped shell 100.Such as, as required, can be shaped as the housing 100 being only formed with base plate 110, sidewall 120, shield 130 and diffuser plate engagement groove 180, also can be shaped as the housing 100 being 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 surface.With reference to Figure 11 and Figure 12, when comprising upper plate 140 for replacement shield 130, the mid portion of the medial surface of sidewall 120 or the medial surface of the sidewall 120 close with upper plate 140 can be formed with diffuser plate engagement groove 120.

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

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

If described in detail further, when manufacture all parts that forms housing 100 respectively and in conjunction with, the contact of complete face cannot be realized between parts, but the point cantact of part.Therefore, the heat being 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 be used as radiator body by the parts of whole housing 100 fully.In contrast to this, molding by extrusion and integrally formed go out housing 100 when, because whole housing is parts, therefore the heat producing self-luminescent part 200 or power control part 20 to arrive the process of shield 130 through sidewall 120 from base plate 110 and is evenly transmitted, and therefore has excellent exothermal effect.

Additional information is carried out for exothermal effect.As described in the 5th embodiment, the optional feature forming housing 100 can be formed in the lower end of outermost shield 130, the object forming optional feature is that the surface area increasing 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, also can form louver, and can be formed concavo-convex on shield 130 or sidewall 120 and play the effect of heat release pin while formation closed surface.

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

The lighting device being formed with shield 130 has specific shield and limits angle θ, and therefore limiting diffuser plate 300 in the θ of angle at this shield can not directly 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 covering restriction angle θ and shield angle α of the lighting device according to embodiment.With reference to Figure 41, with the shield 130 of Figure 41 unlike, in order to reduce dazzle make shield 130 according to sidewall 120 almost mode in line formed, then shield limits that angle θ can reduce and shield angle α can increase, and this means to there is not dazzle in the angle being greater than shield and limiting angle θ.Therefore, as long as leave the fatigue that lighting device just can reduce the eyes caused because of dazzle a little.

On the contrary, with the shield 130 of Figure 41 unlike, if form shield 130 according to the mode being almost parallel to sidewall 120, then shield limits angle θ can increase and shield angle α can reduce, although this mean be greater than shield limit angle θ angle in there is not dazzle, but due to shield limit angle θ excessive, even if 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 there is the advantage that shadow surface is broadened.

Thus, the lighting device penetrating field area around increase illumination need increase shield restriction angle θ, and limits angle θ around preventing the lighting device of dazzle from need reduce shield.

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

The base plate 110 of housing 100 must be configured with illuminating part 200, therefore base plate 100 has the width and length that can configure illuminating part 20, the position that sidewall 120 and shield 130 contact can form diffuser plate engagement groove 180, the fixed projection 430 of diffuser plate 300 and/or reflecting plate 400 can be accompanied in diffuser plate engagement groove 180.Diffuser plate engagement groove 180 can be the shape extended 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 a sliding manner, if at least one end of housing 100 in conjunction with side lid 40, then diffuser plate 300 and/or reflecting plate 400 are fully firmly fixed.Therefore, after lighting device is set, is no matter in use or in transit, all can not worries 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 extends in vertical direction with base plate 110, but not requirement must be vertical, in fact with subvertical mode extend also cannot, and also can according to from base plate 110 more away from launch more outward tilt mode formed.

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