Description
本創作係有關於一種發光二極體燈泡，特別是有關於一種具有透光性之塑膠散熱裝置的發光二極體燈泡。The present invention relates to a light-emitting diode bulb, and more particularly to a light-emitting diode bulb having a light-transmissive plastic heat sink.
傳統發光二極體燈泡的散熱裝置，主要係使用金屬材質的散熱裝置，例如常見的鋁製散熱裝置。然而由於鋁擠或壓鑄等一體成型之製作過程複雜，造成生產費時且加工費用高昂，除此之外也容易造成金屬製散熱裝置與電路板之間的短路，必須特別設計以避免短路發生。另外金屬製散熱裝置還具有重量較重之缺點。前述之種種缺點導致傳統發光二極體燈泡無法普及化。The heat sink of the conventional light-emitting diode bulb is mainly made of a metal heat sink, such as a common aluminum heat sink. However, due to the complicated manufacturing process of integral molding such as aluminum extrusion or die casting, the production is time consuming and the processing cost is high, and in addition, it is easy to cause a short circuit between the metal heat sink and the circuit board, and must be specially designed to avoid a short circuit. In addition, the metal heat sink has the disadvantage of being heavy. The aforementioned shortcomings have led to the inability to popularize conventional light-emitting diode bulbs.
最近已有將發光二極體燈泡的散熱裝置改良成塑膠製的做法，此種作法相較上述金屬材質的散熱裝置，具備簡單、快速生產、成本降低及輕量化等眾多優點。一般的做法是以塑膠中加入石墨或陶瓷粉的方式提高此塑膠之導熱係數，使該塑膠具備良好的導熱及散熱能力。然而這種做法將使該塑膠呈現不透光狀態，因此使得以此不透光塑膠製作的散熱裝置的燈泡只有前端透明燈罩的部分可以透光，導致此發光二極體燈泡的出光角度大幅減少，而且也使得發光二極體運作時所產生之紅外線熱能容易被包覆在燈體內而不易散去。Recently, the heat sink of the light-emitting diode bulb has been improved into a plastic system. This method has many advantages such as simple, rapid production, cost reduction, and light weight compared with the above-mentioned metal heat sink. The general practice is to increase the thermal conductivity of the plastic by adding graphite or ceramic powder to the plastic, so that the plastic has good heat conduction and heat dissipation capability. However, this method will make the plastic opaque, so that the bulb of the heat dissipating device made of the opaque plastic can only transmit light to the portion of the front transparent lamp cover, which causes the light-emitting diode of the light-emitting diode to be greatly reduced. Moreover, the infrared heat energy generated when the light-emitting diode is operated is easily covered in the lamp body and is not easily dispersed.
另外在目前常見之發光二極體燈泡，其內部通常包含3至5顆使用電流350mA以上之高功率發光二極體單元。這種使用高功率發光二極體單元之燈泡會使得燈具耗電量較大且產生較高溫度。In addition, in the conventional light-emitting diode bulb, the inside thereof usually contains 3 to 5 high-power light-emitting diode units using a current of 350 mA or more. Such a bulb using a high power light emitting diode unit will result in a larger power consumption and a higher temperature.
有鑑於此，為改善習知發光二極體燈泡之缺點，本創作提出一種發光二極體燈泡，其包括一具透光性之塑膠散熱裝置、 一發光二極體模組、一驅動電路模組、一具透光性之塑膠燈罩、以及一金屬轉接座。上述具透光性之塑膠散熱裝置具有一承載部以及一位於該承載部下方之容置空間。上述發光二極體模組，具有複數個發光二極體單元，該等發光二極體單元呈放射狀排列且承載於該承載部上。上述驅動電路模組，容置於上述容置空間內。上述具透光性之塑膠燈罩，固定於該具透光性之塑膠散熱裝置之上緣。上述金屬轉接座，具有螺紋且配置於具透光性之塑膠散熱裝置之下方。In view of the above, in order to improve the shortcomings of the conventional light-emitting diode bulb, the present invention proposes a light-emitting diode bulb, which comprises a translucent plastic heat sink, A light-emitting diode module, a driving circuit module, a translucent plastic lamp cover, and a metal adapter. The translucent plastic heat sink has a carrying portion and an accommodating space below the carrying portion. The light emitting diode module has a plurality of light emitting diode units, and the light emitting diode units are radially arranged and carried on the carrying portion. The driving circuit module is disposed in the accommodating space. The light transmissive plastic lamp cover is fixed on the upper edge of the translucent plastic heat dissipating device. The metal adapter is threaded and disposed under the translucent plastic heat sink.
根據上述構想，其中該發光二極體燈泡，包含一具有螺紋之連接裝置，該連接裝置容置於該容置空間內，且該金屬轉接座旋接塑膠散熱裝置於連接裝置之螺紋。According to the above concept, the light-emitting diode bulb comprises a threaded connecting device, the connecting device is received in the receiving space, and the metal adapter is screwed to the thread of the connecting device.
根據上述構想，其中該具透光性之塑膠燈罩與該具透光性之塑膠散熱裝置之結合符合A19燈泡之尺寸。According to the above concept, the combination of the translucent plastic lamp cover and the translucent plastic heat dissipating device conforms to the size of the A19 bulb.
根據上述構想，其中該具透光性之塑膠燈罩與該具透光性之塑膠散熱裝置之結合具有介於300度至360度之間之出光角度。According to the above concept, the light transmissive plastic lamp cover and the light transmissive plastic heat sink have a light exit angle of between 300 degrees and 360 degrees.
根據上述構想，其中該具透光性之塑膠散熱裝置之外表面設有複數個散熱鰭片。According to the above concept, the outer surface of the translucent plastic heat sink is provided with a plurality of heat dissipating fins.
根據上述構想，其中該發光二極體單元為一額定電流介於20mA至30mA之低功率發光二極體單元。According to the above concept, the light emitting diode unit is a low power light emitting diode unit with a rated current between 20 mA and 30 mA.
根據上述構想，其中該等發光二極體單元之數量為60至66個。According to the above concept, the number of the light emitting diode units is 60 to 66.
根據上述構想，其中該等發光二極體單元呈三層之放射狀分布。According to the above concept, the light-emitting diode units are radially distributed in three layers.
根據上述構想，其中該具透光性之塑膠燈罩具霧化內面。According to the above concept, the translucent plastic lampshade has an atomized inner surface.
根據上述構想，其中該具透光性之塑膠散熱裝置之透光率介於75%至100%之間。According to the above concept, the transmissive plastic heat sink has a light transmittance of between 75% and 100%.
本創作之發光二極體燈泡，使用了製作光學鏡片等級之具備良好散熱性之透明塑膠聚合物來作為散熱裝置之材料，此透明塑膠散熱裝置可快速地將熱能傳導至散熱鰭片、且發光二極體 模組產生之紅外線熱能更不容易被包覆在燈體內，因此本創作中之塑膠散熱裝置具備透光性之外也具備良好的散熱性。以此具備透光性散熱裝置製作而成之發光二極體燈泡，與目前習知的不透光散熱裝置之發光二極體燈泡相比，本創作之發光二極體燈泡的出光角度大幅增加，改善了習知的塑膠散熱裝置之發光二極體燈泡之照明死角問題。另外與傳統金屬材質散熱裝置之發光二極體燈泡相比，本創作之發光二極體燈泡除了上述出光角度增加之外，更具備簡單、快速生產、成本降低及輕量化等眾多優點。The light-emitting diode bulb of the present invention uses a transparent plastic polymer having a good heat dissipation property for producing an optical lens grade as a material of a heat sink device, and the transparent plastic heat sink device can quickly transfer heat energy to the heat sink fins and emit light. Dipole The infrared heat generated by the module is less likely to be coated in the lamp body. Therefore, the plastic heat sink of the present invention has good light dissipation as well as good heat dissipation. The light-emitting diode bulb made of the light-transmitting heat-dissipating device has a greatly increased light-emitting angle of the light-emitting diode bulb of the present invention compared with the conventional light-emitting diode bulb of the opaque heat-dissipating device. The problem of the illumination dead angle of the light-emitting diode bulb of the conventional plastic heat sink is improved. In addition, compared with the light-emitting diode bulb of the conventional metal heat sink, the light-emitting diode bulb of the present invention has many advantages such as simple, rapid production, low cost and light weight, in addition to the above-mentioned light-emitting angle.
另外，由於本創作之發光二極體燈泡使用電流介於20mA至30mA之低功率發光二極體單元，經過最佳化15串4並、30或33串2並，一共60至66顆低功率發光二極體單元之設計，相較習知高功率發光二極體燈泡之每小時6至8瓦的耗電量，本創作能以較低之每小時5至6瓦之耗電量達成相同之光通量，一般而言此光通量介於400至550流明之間；習知高功率發光二極體燈泡之產生溫度約85至100度，相較之下本創作之發光二極體燈泡平均產生溫度僅60至75度；另外本創作之發光二極體燈泡具有超過0.95PF(Power Factor，功率因數)之高電力運用效率。由以上可知本創作之發光二極體燈泡具備較低溫、降電壓幅度較小，電源轉換效率較高之優點。In addition, since the light-emitting diode bulb of the present invention uses a low-power light-emitting diode unit with a current between 20 mA and 30 mA, it is optimized to have 15 strings of 4, 30 or 33 strings of 2, and a total of 60 to 66 low powers. The LED unit is designed to achieve the same power consumption of 5 to 6 watts per hour compared to the current 6 to 8 watts of power consumption of a conventional high power LED bulb. The luminous flux generally ranges from 400 to 550 lumens; the conventional high-power light-emitting diode bulb produces a temperature of about 85 to 100 degrees, compared to the average temperature of the light-emitting diode bulb of the present invention. Only 60 to 75 degrees; in addition, the light-emitting diode bulb of the present invention has a high power utilization efficiency of more than 0.95 PF (Power Factor). It can be seen from the above that the light-emitting diode bulb of the present invention has the advantages of lower temperature, lower voltage drop amplitude and higher power conversion efficiency.
