Connector 130 is bars LED module being connected to embedded enclosure.LED module is coupled to embedded enclosure by this connector.LED module is implemented to the coupling of embedded enclosure by the mode of first end and the second end that LED module and embedded enclosure are connected respectively to connector.Connector also can adopt curved shape but not shaft-like.As required, connector 130 and LED module 120 can integratedly with embedded enclosure 110 be formed.
Bracket 140 is in order to be fastened to the bottom of ceiling by the embedded enclosure be arranged in the installation depression of ceiling.For embedded enclosure is reliably fixed to ceiling, there is undesirable from ceiling coming off to prevent the embedded enclosure embedded in the installation depression of ceiling in bracket 140.Bracket can be realized by multiple known method.Such as, bracket 140 can be arranged on connector, and is configured to adjust bracket height by the well-known mode screwing or unscrew bolt.In the case, when screwing bolt after being arranged on by embedded enclosure in installation depression, the bracket 140 being connected to bolt moves along bolt thread 141, and its height (position) is lowered thus.The lower end of bracket 140 that highly (position) is lowered can apply active force to the neighbouring part bottom ceiling.By means of this thrust, embedded enclosure can be more reliably fixed on to be installed in depression.In addition, the bracket embedded enclosure be arranged in installation depression being fastened to the bottom of ceiling can also be realized by other various ways.
Reflector 200 is for reflecting the light launched from LED module.Reflector 200 is configured to removably be coupled to embedded enclosure.For this reason, reflector 200 has conical structure, and the top and bottom of described conical structure are open.That is, reflector 200 is removably coupled to embedded enclosure 100, makes the emitting surface 120a of LED module be arranged in the upper end 240 of the opening of conical structure, and light is launched into outside by open lower end 250.Thus, the light being arranged on the LED module on the upper end 240 of the opening of cone-shaped reflector is after cone-shaped reflector, and the lower end 250 through the opening of cone-shaped reflector is launched into outside.In addition, the reflector that top and bottom open can adopt various shape, comprises corner taper, triangular pyramid, etc.
More specifically, the reflector 200 with conical structure comprises open upper end 240, open lower end 250, connects the upper end 240 of this opening and the sidewall 230 of the lower end 250 of opening, and in flexible and dismountable mode reflector being coupled to the detachable erecting device 210 and 220 in the vertical projections 111 of embedded enclosure.
This detachable erecting device is convenient to reflector 200 be coupled to embedded enclosure 100 or pull down reflector 200 from embedded enclosure 100.For this reason, this detachable erecting device comprises around the frame body 210 of the sidewall of reflector 200 with from the outstanding locking body 220 of frame body 210.Each locking body 220 comprises curved surface 222 and the guidance surface 221 of " L " shape.By the curved surface 222 of locking body is locked onto vertical projections 111, reflector is coupled to embedded enclosure 100.Specifically, when reflector 200 is pushed in embedded enclosure 100, the guidance surface 221 of locking body can move along the sidewall of vertical projections 111, and the curved surface 222 being then positioned at the end of corresponding guidance surface is locked to the upper end of the vertical projections 111 of embedded enclosure.In such a way, reflector 200 can be easily mounted on embedded enclosure 100.Preferably, the angle between curved surface 222 and guidance surface 221 is less than 90 °.Each locking body 220 is made by plastics such as such as Merlon or ABS (acrylonitrile-butadiene-styrene (ABS)) resins, to possess suitable elasticity.In addition, lock body 220 can integratedly with reflector 200 be formed.
The angle that curved surface bends is preferably the angle of non-90 degree, makes when needed, is separated with embedded enclosure 100 even if adopt less power also easily can make to lock by " L " shape the reflector 200 that body 220 is coupled to embedded enclosure.For achieving the above object, curved surface 222 is configured to, and makes the angle of bend from the outstanding curved surface 222 of frame body 210, is the obtuse angle larger than the level angle of the flange surface 112 of flatly giving prominence to from open lower end 250.Thus, by means of the obtuse angle of curved surface, when pulling down reflector with hand, although the locking body 220 of reflector has been locked to the vertical projections 111 of embedded enclosure, can easily reflector be separated with embedded enclosure.
Fig. 5 shows according to embodiments of the invention, by the process that reflector is separated from embedded enclosure.If user uses its (his or her) pronation to pull reflector (as shown in Figure 5 a, this reflector is coupled to embedded enclosure 110 by the curved surface mode locked onto on embedded enclosure 110 of the locking body 220 by reflector), then can slide on embedded enclosure 110 easily with the curved surface of the obtuse angle being greater than 90 °, as shown in Figure 5 b.Thus, as shown in Figure 5 c, reflector can be separated with embedded enclosure easily.
The lower end 250 of the opening of reflector comprises the flange surface 201 of the outward flange horizontal-extending along open lower end 250.When reflector and embedded enclosure are assembled, the flange surface 201 of open lower end 250 forms close contact with the lower surface of the ring body 110 of embedded enclosure.
The emitting surface 120a of LED module is arranged in open upper end 240.The light launched from LED module, before the lower end 250 of opening through cone-shaped reflector is launched, first passes through cone-shaped reflector downwards.At this, from LED module launch light by the internal surface reflection of the sidewall of cone-shaped reflector, be then transmitted to below open lower end 250, simultaneously formed a predetermined light distribution range.Light distribution range refers to the distribution being transmitted into the light of a requisite space from a light source.Light distribution range changes with the curvature of the inner surface of the sidewall of reflector.
Sidewall 230 is the connecting surfaces connecting open upper end and open lower end.The inner surface of sidewall 230 has predetermined curvature.
This curvature represents the degree of crook of the inner surface of the sidewall 230 of reflector.Therefore, increase curvature and mean that the inner surface of sidewall is closer to plane.Reduce curvature and then mean that the degree of crook of side wall inner surfaces increases.
According to the difference of curvature (namely representing the degree of crook of the inner surface of the sidewall 230 of reflector), can change from the distribution situation of the light of emitting surface transmitting.If this curvature is relatively large, the sidewall of reflector will closer to plane, thus make the distribution of light relatively little.In other words, convergence of rays is burnt in a relatively little region, but not scatters on a large scale.On the other hand, if this curvature is relatively little, the degree of crook of the sidewall 230 of reflector can be larger, makes the distribution of light relatively large.In other words, light is scattered more widely, but not is concentrated.
Fig. 6,7 and 8 be according to an embodiment of the invention light distribution range with the schematic diagram of the Curvature varying of the side wall inner surfaces of reflector.In these three kinds of situations, Fig. 6 show curvature maximum time light distribution range, the situation that Fig. 7 is curvature when being second largest, and light distribution range when Figure 8 shows that curvature is minimum.
Fig. 6 show curvature relatively large time light distribution range.The light distribution range of the reflector in Fig. 6 is 20 °.The curvature of the reflector in Fig. 7 is less than the curvature of the reflector in Fig. 6, the light distribution range of the reflector in Fig. 7 is 30 °, be greater than the light distribution range of Fig. 6, because the degree of crook of the side wall inner surfaces of its reflector is larger than the degree of crook of the side wall inner surfaces of the reflector in Fig. 6.The curvature of the reflector in Fig. 8 is less than the curvature of the reflector in Fig. 7, and its light distribution range is 60 °, large than in Fig. 7, because the degree of crook of its reflector side wall inner surface is larger than the degree of crook of the side wall inner surfaces of the reflector in Fig. 7.Thus, can be understood as, along with the reduction of curvature, light distribution range increases; And along with the increase of curvature, light distribution range can reduce.
Thus, according to embodiments of the invention, inner surface can be provided to have some reflectors of different curvature.When needs realize the first light distribution range, only the first reflector had corresponding to the first curvature of the first light distribution range must be coupled with embedded enclosure.When needs change light distribution range, such as, change into the second light distribution range, only the second reflector had corresponding to the torsion of the second light distribution range must be coupled with embedded enclosure.
Figure 10 shows process reflector being coupled to embedded enclosure according to an embodiment of the invention.Being recessed in ceiling after formation in the installation for installing lighting device, embedded enclosure being inserted and installs in depression, as shown in Figure 10 a.Subsequently, as shown in fig. lob, after embedded enclosure has been embedded in installation depression, the bolt being connected to the bracket be arranged on connector has been screwed.Subsequently, the height (position) being connected to the bracket of bolt is lowered, and makes the lower end of bracket can apply active force to the adjacent part that caves in installation in the bottom of ceiling.By means of this thrust, embedded enclosure is fixed on to be installed in depression.Next, as shown in figure l oc, reflector is inserted into and pushes in embedded enclosure, till the curved surface by the locking body by reflector locks onto embedded enclosure thus makes reflector be secured on embedded enclosure.Subsequently, as shown in fig. 10d, the assembling of embedding type illuminator and installation.Preferably, reflector is furnished with the protective cover 91 of the lower end 250 of the opening being attached to reflector.Prevent dust from entering in reflector when protective cover 91 is both for embedding at reflector and being arranged in embedded enclosure, also for preventing fingerprint or electrostatic.Thus, after reflector installation, protective cover 91 can be removed from reflector.For this reason, protective cover 91 is made up of transparent material (such as, PET), it is attached on reflector by a kind of pressure-sensitive cement, and can removes from reflector easily when needed.
In one embodiment, the inner surface of the sidewall of reflector can coated whitewash, and light distribution range can be changed.Such as, if apply whitewash on the inner surface of the sidewall of reflector, although the sidewall curvature of reflector is identical with the sidewall curvature of reflector in Fig. 8, light distribution range can be extended to 75 °, as shown in Figure 9.Whitewash can be the paint for resin (raw materials of plastics).
In one embodiment, predetermined pattern is formed in the inner surface that reflector can be configured such that the sidewall of reflector.The formation of this pattern can change light distribution range.Multiple patterns can be formed in the inner surface of the sidewall of reflector.Such as, as shown in figure 11, the pattern formed in the inner surface of the sidewall of reflector can be honeycomb pattern, to form predetermined Light distribation.
In addition, the reflector with predetermined curvature can have various structures, such as focusing structure, narrow structure, expansion structure etc.According to application target, the reflector with corresponding construction is coupled to embedded enclosure.As a reference, Figure 12 shows the photo of the multiple embedding type illuminator of all kinds of reflectors with different embodiment according to the subject invention.
Meanwhile, although detachable erecting device can separate with reflector formed, it also can integratedly with reflector be formed.As shown in figure 13, reflector and detachable erecting device can adopt same material integration to generate.Such as, reflector and detachable erecting device can correspond to the mould of reflector and detachable installed part by integral injection molding by shape.As a reference, Figure 13 shows a kind of photo of product, and this product comprises the reflector with detachable erecting device of integration.
