New Description: [New Technology Area] This creation is about a Light Emitting Diode (LED) luminaire, especially a module that can be used indoors and outdoors without being separately packaged in a lampshade. Luminous LED lamps. [Prior Art] Since the conventional tungsten filament bulb has a short life span, the industry has been actively developing new alternatives, and LED lamps have been proposed. Even though newly developed LED lamps have the advantages of low power consumption, long component life, and fast response, LED components are more sensitive to heat. Under long-term continuous use, its heat dissipation requirements cannot be ignored. Circle 1 is a conventional street lamp construction. Because the outdoor application lamp is waterproof and dustproof, the bulb 1 is sealed in a closed casing 2, and a closed space is constructed, so that the heat sink 3 for the bulb 1 is trapped inside and cannot be discharged and dissipated to the outside. Environment β It can be seen that since the lamps used in outdoor applications must take into account the stricter waterproof and dustproof standards, such as the commonly used (7)^ specification, if LED components are used as the illumination source of outdoor lamps, it often leads to heat dissipation problems that are difficult to solve. A variety of techniques to enhance heat dissipation are applied to outdoor LED street lights, such as with a fan for forced convection, or with heat pipe components. Regardless of which of the above solutions, the root problem is still encountered: the LEC> module is completely sealed, that is, the heat sink responsible for heat dissipation is sealed in a sealed enclosure by the 3 M428303, and the heat is concentrated in the confined space. [New Content] The main purpose of this creation is to provide a modular light-emitting diode lamp that can be used in both indoor and outdoor applications to avoid the problem of poor water and liquid intrusion. In order to achieve the above object, the modular light-emitting diode lamp of the present invention comprises a heat sink, a light-emitting unit, a light-transmitting plate and a waterproof sealing ring. The heat sink includes a first side and a second side, wherein the first side is recessed with an accommodating space, and the second side is provided with at least one venting hole connected to the accommodating space ′ and each venting hole is covered There is a breathable patch, so it has a venting function to allow the hot gas inside the accommodating space to be discharged at the right time to avoid fogging of the glass due to internal moisture. The light-emitting unit is housed in the accommodating space and includes a circuit board and a plurality of light-emitting diodes disposed on the circuit board. The waterproof sealing ring is sandwiched between the light-transmitting plate and the first side of the heat-dissipating seat, wherein the light-transmitting plate covers the accommodating space. With the above modular lamp structure design, since the heat sink is exposed to the external environment, it not only has the advantages of low power consumption and long life of the LED lamp, but also solves the heat dissipation problem sensitive to the LED component. The special waterproof and dustproof design also allows the luminaires of this creation to comply with the IP65 specification. The modular luminaires of this creation can also be applied to indoor hanging or wall-mounted luminaires through additional mechanisms. 8 The waterproof sealing ring can be made of rubber or SBR foam. The venting holes in this creation can be overlapped. On the board and / or off the circuit M428303 board. A fin structure may be formed on the second side of the heat sink. The light-emitting unit may further include a plurality of lens-corresponding configurations adjacent to the plurality of light-emitting diodes for achieving a specific light-emitting purpose. The first side of the heat sink can be further formed with an arc-shaped positioning surface and a plurality of screw holes on both sides of the curved positioning surface, so that the arc-shaped light rod can be directly pressed against the curved positioning surface by a fixing piece, and the screw is screwed The screw hole that passes through the fixing piece and locks into the heat sink becomes a standard street light. [Embodiment] Referring to Figures 2 to 5', respectively, an exploded view of a modular LED lamp of a preferred embodiment, a plan view and a cross-sectional view viewed from different angles of view. The LED modular LED lamp shown in the figure mainly comprises a heat sink 1〇, a light emitting unit 20, a waterproof sealing ring 3〇, a light transmitting plate 31, a lens holder, a fixing frame 33 and a buffer. Unit 34. The heat sink 10 includes a first side 1 〇丨 and a second side 102, and has a substantially quadrilateral profile as viewed from either side. The first side 101 is recessed to define an accommodating space. 1 〇 3, the second side 1 〇 2 is formed with a fin structure 106 for helping to dissipate heat. The illuminating unit 20 includes a circuit board 21 and a plurality of LEDs 22 disposed on the circuit board 21. The illuminating unit 2 〇 further includes a plurality of lenses 23, Corresponding to the plurality of LEDs 22. The plurality of lenses 23 are disposed adjacent to the plurality of pixels 22 to enable the LEDs 22 to emit light in a specific manner. In this embodiment, the plurality of bolts 41 are used to lock the circuit board to the heat sink, ensuring 5 M428303 lens holder 32 is used to support the positioning of the above complex lens 23, and thus is spaced apart from the circuit board 21 by a distance of about the height of the lens 23. Here, bolts 42 can also be used simultaneously through the lens holder 32 and the circuit board 21. And locked into the heat sink 10, The fixing effect of the lens holder 32 is achieved. The present invention covers the accommodating space 103 with a light-transmitting plate 31 such as a light-transmitting plate made of glass, so that the light-emitting unit 20 and the lens holder 32 are sealed in the accommodating space 103. In order to take into account the waterproof requirement of the light-emitting unit 20, the waterproof sealing ring 30 is sandwiched between the light-transmitting plate 31 and the first side 1〇1 of the heat sink 10. The waterproof sealing ring 30 is made of rubber material in this example, and is implemented in other embodiments. In the example, the styrene-butadiene rubber (SBR) foamed cotton material may be used. The fixing frame 33 is used for pressing the light-transmitting plate 31 to the heat-dissipating block 1 , which is substantially rectangular, and is also The bolt 43 passes through the fixing frame 33 and is locked into the heat sink 10 for a fixed purpose. In order to prevent such a pressing force from causing damage to the light-transmitting plate 31, it may be additionally sandwiched between the fixing frame 33 and the light-transmitting plate 31. A buffer unit 34 is provided. In the embodiment, the buffer unit 34 is formed by a plurality of elastic strips 341 and distributed along a rectangular outline of the fixed frame 33. In addition, the heat sink 10 is further provided with two vent holes on the second side 102. 1〇4,105 and an outlet hole 36. The venting holes 1〇41〇5 and the outlet holes 36 are all communicated with the accommodating space 103, and in particular, each venting hole ι〇4,1〇5 is covered with a gas permeable patch 35 in the outlet hole. 36. A waterproof joint 37 is installed. The use of the above-mentioned ventilating patch 35 achieves a waterproof effect on the one hand, and mainly allows air to circulate to promote heat exchange on the other hand, and avoids water droplets in the accommodating space 1 〇 3 due to high temperature. The breathable patch 35 is a product provided by the company, but is of course not limited thereto. The external power transmission line (not shown) on the circuit board 21 of the M428303 is concentrated by the outlet hole 36, and The use of the waterproof joint 37 also ensures that the liquid does not intrude into the accommodating space 103 from the outside. Referring to Figures 2 and 6, Figure 6 is a schematic illustration of the application of a modular LED luminaire to a street light. It is shown that when the modular LED lamp of the present invention is applied to an outdoor occasion such as a street lamp, the arc lamp bar 44 is only required to abut against the arc-shaped positioning surface 1〇7 of the second side 102 of the heat sink 10, and the other is matched. The mounting step of the lamp is completed by using a fixing piece 45 and a plurality of bolts 46' to pass the bolts 46 through the fixing piece 45 to lock the lamp post 44 and the screw holes 108 of the second side 102 of the heat sink 10. It can be seen from the above that the creative feature is that the modular luminaire is used to expose the heat sink directly to the external environment. Compared with the conventional one, it must be cooled slowly by the sealed casing. Moreover, the light pole can be directly clamped to the heat sink without separately providing a mechanism. In terms of waterproofing, the modular LED luminaire of this creation achieves waterproof effect by waterproof sealing ring and breathable patch, and the high-heat gas inside the accommodating space is timely discharged by the venting function of the venting patch. The gas causes the glass to fog. The luminaire design of this creation can be verified to meet the IP65 standard, and it is not only suitable for outdoor use, but also can be applied to indoor hanging or wall-mounted luminaires through additional mechanisms. The above embodiments are only examples for convenience of explanation. The scope of the claims claimed herein is based on the scope of the patent application, and is not limited to the above embodiments.
