Below will be elaborated for the concrete structure of lighting device:

Consult Fig. 2, Fig. 3, Fig. 4 and Fig. 5, it is one square that framework 1 outward appearance is, framework 1 also comprises and two the second sidewalls 12 that are connected in the first side wall 11 opposition sides, each second sidewall 12 comprises an outer wall 121 and an inner wall 122, each outer wall 121 comprises an internal face 123 and an end face 124, and each inner wall 122 is convexly set in internal face 123 and is adjacent to end face 124.

Blooming piece unit 2 is arranged at two the first side walls 11 of framework 1 and the inside of 2 second sidewalls 12; comprise that optical thin film 22, that the baffle 21, that defines bottom 202 is stacked and placed on baffle 21 tops is stacked and placed on the LGP 23 of optical thin film 22 tops, and one is stacked and placed on LGP 23 tops and defines the reflecting plate 24 on top 201.In this preferred embodiment, baffle 21 is transparence, and optical thin film 22 is diffusion barrier (Diffuser), and the light of injecting optical thin film 22 via LGP 23 can be spread by optical thin film 22 and expose to outside framework 1 via baffle 21.

Support unit 3 comprises four bolster stakes 31, and every two bolster stakes 31 in described bolster stake 31 plug the outer wall 111 of corresponding the first side wall 11 and are supported in the bottom 202 of the baffle 21 of blooming piece unit 2.

The inner wall 112 of each the first side wall 11 forms two bolt apertures 115 that are respectively adjacent to the second sidewall 12, each loading plate 4 forms two through holes 41 corresponding with bolt apertures 115 positions of two the first side walls 11 respectively, each fixed cell 5 comprises two locking screws 51, each locking screw 51 is arranged in corresponding through hole 41 screw lock in the bolt apertures corresponding with through hole 41 115, whereby, loading plate 4 is locked in to the inner wall 112 of two the first side walls 11.The upper surface 42 that the upper supporting part of loading plate 4 is this loading plate, loading plate 4 is formed with a plurality of screws 43 (Fig. 5 only shows one of them) separately, lamp bar 6 comprises that one is resisted against the circuit board 61 of upper surface 42, a plurality of light emitting diode 62 that is arranged at circuit board 61 that is spaced, and a plurality of screws 63.Circuit board 61 forms a plurality of perforation 611 corresponding with described screw 43 positions respectively, each screw 63 is arranged in corresponding perforation 611 screw lock in the screws 43 corresponding with perforation 611, whereby, be locked in loading plate 4 and make circuit board 61 be positioned upper surface 42 with the circuit board 61 by lamp bar 6.

Need first illustrate, the assembling of lighting device and start relation for convenience of description, in the following description, Fig. 4 and Fig. 5 only present the assembled relation of a loading plate 4 and a lamp bar 6.

Consult Fig. 2 and Fig. 5; during wish assembling lighting device; at first blooming piece unit 2 is inserted in framework 1; make the top 201 of reflecting plate 24 be butted on inner wall 112 bottoms of two the first side walls 11 and inner wall 122 bottoms of two the second sidewalls 12; from bottom to top sequentially stacked baffle 21, optical thin film 22 and LGP 23, more every two bolster stakes 31 in described bolster stake 31 are plugged to the outer wall 111 of corresponding the first side wall 11 and be supported in the bottom 202 of the baffle 21 of blooming piece unit 2.

Consult Fig. 4 and Fig. 5, on the other hand, first two lamp bars 6 are assembled in respectively to the upper surface 42 of loading plate 4, by each screw 63, are arranged in the perforation 611 of corresponding circuits plate 61 screw lock in the screw 43 of the loading plate 4 corresponding with perforation 611, make each lamp bar 6 be positioned the upper surface 42 of loading plate 4.Then, will be arranged in by two locking screws 51 of fixed cell 5 through hole 41 of corresponding loading plate 4 screw lock in the bolt apertures 115 of the inner wall 112 of the first side wall corresponding with through hole 41 11, complete the assembling lighting device.Because the light produced from lamp bar 6 is incident to blooming piece unit 2 and the mode through it reflects framework 1 belongs to existing skill, be not described in detail in this.

Consult Fig. 6, when wish is changed one of them of two lamp bars 6 of lighting device, two locking screws 51 of each fixed cell 5 are separated to the bolt apertures 115 of the first side wall 11, now, loading plate 4 and lamp bar 6 can be moved apart to framework 1 simultaneously, then, change one group of new loading plate 4 and lamp bar 6 simultaneously, and, after by locking screw 51, it being locked in to the first side wall 11 again, complete the operation of replacing, can reach the effect that fast assembling-disassembling is changed.Finally, the loading plate 4 changed, together with lamp bar 6, can be taken back to storeroom, then lamp bar 6 is changed to non-defective units in loading plate 4, become spare unit, when changing next time, take out and use.It is worth mentioning that, in the present embodiment, loading plate 4 is made by for example metal material for aluminium, and while making lamp bar 6 be installed on loading plate 4, thermal diffusivity is better.

Consult Fig. 2, it should be noted that, although in the present embodiment, lighting device comprises two loading plates 4, two fixed cells 5, reach two lamp bar 6 assembling cooperations and form, so not as limit, lighting device also can only comprise a loading plate 4, a fixed cell 5, reach lamp bar 6 assembling cooperations and form, also the effect of attainable cost invention.

Consulting Fig. 7 and Fig. 8, is the second preferred embodiment of lighting device of the present invention, with the Main Differences of the first preferred embodiment be the enforcement aspect of the another kind combination kenel of the upper supporting part of loading plate 4 and lamp bar 6.

Upper supporting part is a socket 44, socket 44 forms an opening up slot 45, lamp bar 6 comprises that one is plugged in the circuit board 61 of slot 45, a plurality of light emitting diode 62 that is arranged at circuit board 61, and two keepers 64 that are arranged at respectively circuit board 61 end opposite and removably are engaged in socket 44.In this preferred embodiment, each keeper 64 is made by rubber or plastics.

Assemble the second preferred embodiment and the first preferred embodiment is roughly the same, the difference place is for pulling open two keepers 64 of lamp bar 6 towards export-oriented the first side wall 11, insert and be positioned in the slot 45 of socket 44 with power circuit board 61, then by the inside bonded circuitry plate 61 of two keepers 64.During lamp removal bar 6, according to the abovementioned steps reverse operating.

In sum, lighting device of the present invention, be installed on loading plate 4 by lamp bar 6, and the two-screw by fixed cell removably is fixed in inner wall by loading plate, directly together with lamp bar 6, changes loading plates 4, more efficient, therefore really can reach the object of the invention.

As described above, be only preferred embodiment of the present invention, and when not limiting scope of the invention process with this, i.e. all simple equivalences of doing according to the claims in the present invention content and invention description content change and modify, and all still belong to the scope of patent of the present invention.
