Description

本発明は、灯具に関するもので、特に天井板に埋設して室内または室外の照明を提供することができる灯具に係るものである。   The present invention relates to a lamp, and particularly relates to a lamp that can be embedded in a ceiling plate to provide indoor or outdoor illumination.

従来の埋込み型の灯具としては、例えば中華民国公告第Ｍ３５９６４４号の「灯具の放熱装置」（特許文献１を参照）を参照すると、従来の灯具には一個の基板、一個の環状放熱座、一個のファンと一個のケース蓋が含まれる。基板には二個の表面が含まれ、その内の一個の表面には複数個の発光部材が設けられ、もう一個の表面は環状放熱座を結合することができ、そして基板の二個の表面の間には複数個の気孔が貫穿される。ファンは環状放熱座の上に設けられ、ケース蓋はカバーとして環状放熱座とファンの外部に設けられ、そして基板と結合し、基板に発光部材が設けられた表面は外へ向くように形成される。ケース蓋の上に複数個の通気溝が設けられるため、ファンが回転する時に気流を駆動し、そしてそれぞれの通気溝を経由してケース蓋の内部に進入し、さらに環状放熱座のそれぞれの放熱フィンの周辺を通過した後、再び基板のそれぞれの気孔を経由して吹き出すことにより、それぞれの発光部材に対して放熱を行うという目的を達成することができるようにしたものがある。   As a conventional embedded lamp, for example, referring to the “radiating device for a lamp” (refer to Patent Document 1) of the Republic of China notification No. M359644, the conventional lamp includes one substrate, one annular heat dissipating seat, one Includes a fan and one case lid. The substrate includes two surfaces, one of which is provided with a plurality of light emitting members, the other surface can be coupled with an annular heat dissipating seat, and the two surfaces of the substrate A plurality of pores are penetrated between them. The fan is provided on the annular heat dissipating seat, the case lid is provided as a cover outside the annular heat dissipating seat and the fan, and is connected to the substrate, and the surface on which the light emitting member is provided on the substrate is formed to face outward. The Since a plurality of ventilation grooves are provided on the case lid, the airflow is driven when the fan rotates, and then enters the inside of the case lid via the respective ventilation grooves, and further each heat radiation of the annular heat dissipating seat After passing through the periphery of the fin, there is one that can achieve the purpose of radiating heat to each light emitting member by blowing out again through each pore of the substrate.

中華民国公告第Ｍ３５９６４４号Republic of China Notice No. M359644

従来の埋込み型の灯具においては、灯具は軽量鉄骨または木造装飾の天井板に埋設され、そしてそのケース蓋は天井板の上方に埋め込まれ、基板に発光部材が設けられた表面だけが天井板の表面から露出するように形成されるため、従来の構造のケース蓋のそれぞれの通気溝は天井板の上方に位置するように形成されている。しかし、天井板の上方と建物そのもののセメント製の床の間の空間は一般的に密閉された空間からなるため、その密閉空間は外部の空気と循環でき難い。またその密閉空間には他にその他の物品（例えば管路、線路または断熱材）が設けられるため、気流の流通の効果と放熱効果に影響を及ぼしてしまうという問題点があった。   In a conventional embedded lamp, the lamp is embedded in a lightweight steel frame or wooden decoration ceiling plate, and its case lid is embedded above the ceiling plate, and only the surface on which the light emitting member is provided on the substrate is the ceiling plate. Since it is formed so as to be exposed from the surface, each ventilation groove of the case lid having the conventional structure is formed so as to be positioned above the ceiling plate. However, since the space between the ceiling plate and the cement floor of the building itself is generally a sealed space, it is difficult to circulate the sealed space with external air. In addition, since other articles (for example, pipes, tracks, or heat insulating materials) are provided in the sealed space, there is a problem in that the effect of the air flow and the heat dissipation effect are affected.

上述したように、従来の構造では放熱効果が悪く、そして環状放熱座には熱が溜まり易く、しかもそれぞれの発光部材から生じる熱量をスムーズに排出することができないため、それぞれの発光部材とそのチップが長時間高温の環境に置かれると、その使用寿命に惡影響が生じてしまうという問題点があった。さらに、それぞれの発光部材のチップが熱くなり過ぎると、発光減衰が生じるため、それぞれの発光部材の発光効果に影響を及ぼしてしまうという問題点があった。このように、上記のような従来の灯具をさらに改良しなければならないものであった。   As described above, the heat dissipation effect is poor in the conventional structure, and heat is easily accumulated in the annular heat dissipating seat, and the amount of heat generated from each light emitting member cannot be discharged smoothly. However, if the product is left in a high temperature environment for a long time, there is a problem in that the service life of the product is adversely affected. Furthermore, if the chip of each light emitting member becomes too hot, the light emission is attenuated, which affects the light emitting effect of each light emitting member. Thus, the conventional lamp as described above has to be further improved.

本発明はこのような問題点に鑑みて発明されたものであって、その主な目的とするところは、放熱効果を高めることができる灯具を提供することである。   The present invention has been invented in view of such problems, and a main object thereof is to provide a lamp capable of enhancing the heat dissipation effect.

本発明の第二の目的は、使用寿命を延ばすことができる灯具を提供することである。   The second object of the present invention is to provide a lamp capable of extending the service life.

再び図２を参照すると、本発明の実施例１の灯具を実施する時、外カバー１は天井板９の上方に埋め込まれ、外カバー１の第一フランジ１３は天井板９の表面に貼接するように形成される。ファン３が回転する時、気流は通孔２４を経由して気流通路Ａと第二収容室２１の間において流通すると同時に、気流は放熱器４の周辺を通過し、補助的に発光部材５から生じる熱エネルギーを拡散することができる。そして、本発明においてはファン３の正方向または反対方向への回転の方向を制御することにより、気流の流通の方向を変えることができる。例えば、ファン３が正方向へ回転する時、気流は通気口Ｂと気流通路Ａから吸入され、そして通孔２４を経由して第二収容室２１の放熱器４の周辺に向かって流れ、再びカバー板２５のそれぞれの貫穿孔２５１から排出される。それに反して、ファン３が反対方向へ回転する時、気流はカバー板２５の貫穿孔２５１からそれぞれ吸入され、そして第二収容室２１の放熱器４の周辺を通過した後、順序よく通孔２４を経由して気流通路Ａと通気口Ｂから排出されることにより、補助的に発光部材５から生じる熱エネルギーを拡散することができる。   Referring to FIG. 2 again, when the lamp according to the first embodiment of the present invention is implemented, the outer cover 1 is embedded above the ceiling plate 9, and the first flange 13 of the outer cover 1 is attached to the surface of the ceiling plate 9. Formed as follows. When the fan 3 rotates, the airflow flows between the airflow passage A and the second storage chamber 21 via the through-hole 24, and at the same time, the airflow passes around the radiator 4 and is supplementarily from the light emitting member 5. The resulting thermal energy can be diffused. In the present invention, the direction of the air flow can be changed by controlling the direction of rotation of the fan 3 in the forward direction or the opposite direction. For example, when the fan 3 rotates in the forward direction, the airflow is sucked from the vent B and the airflow passage A, and flows toward the periphery of the radiator 4 of the second storage chamber 21 via the through hole 24. The cover plate 25 is discharged from each through hole 251. On the other hand, when the fan 3 rotates in the opposite direction, the airflow is sucked from the through holes 251 of the cover plate 25 and passes through the periphery of the radiator 4 of the second storage chamber 21 and then passes through the through holes 24 in order. By being discharged from the airflow passage A and the vent B via the heat energy, the heat energy generated from the light emitting member 5 can be diffused as an auxiliary.

しかし、気流の流通方向は何れの方向であっても、本発明の通気口Ｂとそれぞれの貫穿孔２５１は全て天井板９の表面から露出しているため、外部空気とスムースに循環することができる。また、内ケース２の第二フランジ２３は通気口Ｂとそれぞれの貫穿孔２５１の間に阻隔されることにより、灯具から放出される熱気が直ちに吸引されて灯具の中に進入するのを避けることができるため、よりよい気流の流通効果と放熱効果を提供することができる。   However, regardless of the flow direction of the airflow, the vent B and the through holes 251 of the present invention are all exposed from the surface of the ceiling plate 9, so that they can circulate smoothly with the external air. it can. Further, the second flange 23 of the inner case 2 is blocked between the vent B and the respective through-holes 251, thereby preventing the hot air released from the lamp from being immediately sucked and entering the lamp. Therefore, it is possible to provide a better airflow distribution effect and heat dissipation effect.

図３は本発明の実施例２の灯具の組み立てられた状態の断面図である。図３を参照すると、実施例２の灯具にも一個の外カバー１、一個の内ケース２、一個のファン３、一個の放熱器４および一個の発光部材５が含まれる。その内に、内ケース２の第二開口２２にも一個のカバー板２５’が設けられる。   FIG. 3 is a sectional view of the assembled lamp of the second embodiment of the present invention. Referring to FIG. 3, the lamp according to the second embodiment also includes one outer cover 1, one inner case 2, one fan 3, one radiator 4, and one light emitting member 5. Among them, one cover plate 25 ′ is also provided in the second opening 22 of the inner case 2.

The blocking portion 252 'is preferably formed of a single annular wall, and the through-hole 251' is formed so as to be located outside the range surrounded by the blocking portion 252 '. Further, when the cover plate 25 ′ is assembled to the second opening 22 of the inner case 2, the upper edge of the blocking part 252 ′ is in contact with the substrate 41 of the radiator 4, and the light emitting member 5 is surrounded by the blocking part 252 ′. It is formed so as to be located within the range.

そのため、ファン３が正方向へ回転する時、気流は通気口Ｂと気流通路Ａから吸入され、そして通孔２４を経由して第二収容室２１の放熱器４の周辺に向かって流れ、再びカバー板２５’のそれぞれの貫穿孔２５１’から排出される。ファン３が反対方向へ回転する時、気流はカバー板２５’のそれぞれの貫穿孔２５１’から吸入され、そして第二収容室２１の放熱器４の周辺を通過した後、順序よく通孔２４、気流通路Ａと通気口Ｂを経由して排出される。   Therefore, when the fan 3 rotates in the forward direction, the airflow is sucked from the air vent B and the airflow passage A, and flows toward the periphery of the radiator 4 of the second storage chamber 21 via the through hole 24, and again. It is discharged from each through-hole 251 'of the cover plate 25'. When the fan 3 rotates in the opposite direction, the air flow is sucked from the respective through holes 251 ′ of the cover plate 25 ′, and after passing around the radiator 4 of the second storage chamber 21, the air holes 24, the air flow are arranged in order. It is discharged via passage A and vent B.

しかし、気流の流通の方向は何れの方向であっても、本発明の阻隔部２５２’により、発光部材５の発光体５２またはそのチップが外部の空気と接触するのを阻隔することができるため、塵が積もるのを避けることができる。   However, the flow direction of the airflow can be any direction because the light blocking member 252 ′ of the present invention can block the light emitter 52 of the light emitting member 5 or its chip from coming into contact with external air. , Can avoid the accumulation of dust.
