自從愛迪生發明了電燈之後，人類的夜生活也因為有了照明器具，而開始變得多采多姿。尤其在人類的居住型態朝向大型、集中之集合式建築的演變下，照明器具在人類生活所扮演的角色也相形重要。例如，大樓或廠房內之日間照明，便有賴於各種不同照明器具之輔助，而無法只是取用自然光源，於是，照明器具之需求乃不分晝夜，而人類之活動亦可不受限於日夜之循環。Since Edison invented the electric light, human nightlife has become more colorful because of the lighting equipment. Especially with the evolution of human living style towards large, concentrated collective buildings, the role of lighting appliances in human life is also dwarfed. For example, the daytime lighting in a building or factory depends on the assistance of various lighting fixtures, and cannot use only natural light sources. Therefore, the demand for lighting fixtures is day and night, and human activities are not limited to day and night. cycle.
早期之廠房照明用燈具，通常係使用如水銀燈、複金屬燈等各種不同之燈具，以作為照明之發光源。近來，由於發光二極體(Light Emitting Diode，簡稱LED)等半導體晶片具有體積小、省電與壽命長等優點，乃逐漸取代而成為極受歡迎之發光源。惟因發光二極體之體積極小，且照明用之發光二極體的消耗功率相對較高，其所產生之熱能對於發光二極體之發光效能與壽命，實有極大之影響。為了能將發光二極體所產生之熱源順利散逸，高功率之發光二極體燈具通常均會配置有散熱鰭片，以增進發光二極體之發光效能與壽命。In the early days, various types of lamps, such as mercury lamps and double metal lamps, were used as lighting sources for lighting. Recently, semiconductor wafers such as Light Emitting Diodes (LEDs) have advantages such as small size, power saving, and long life. They have gradually replaced and become a very popular light source. However, because the body of the light-emitting diode is very small, and the power consumption of the light-emitting diode used for lighting is relatively high, the heat energy generated by it has a great impact on the light-emitting diode's luminous efficiency and life. In order to dissipate the heat source generated by the light-emitting diode smoothly, high-power light-emitting diode lamps are usually equipped with heat-dissipating fins to improve the light-emitting diode's luminous efficiency and life.
此外，為確保例如是化學工廠、煉油廠等易燃、易爆場所的工作安全，這些場所使用之燈具均須為具有防爆能力之防爆燈具，以符工廠設置之防爆安全規範，避免事故擴大所造成之災害損失。因此，發光二極體防爆燈除了散熱與發光效能的考量外，更應著重在加強燈體的防爆效果。In addition, in order to ensure that flammable and explosive places such as chemical plants, oil refineries, etc.Work safety. The lamps used in these places must be explosion-proof lamps with explosion-proof capability, in accordance with the explosion-proof safety regulations set by the factory to avoid disaster losses caused by the expansion of accidents. Therefore, in addition to the consideration of heat dissipation and luminous efficacy, the light-emitting diode explosion-proof lamp should also focus on strengthening the explosion-proof effect of the lamp body.

However, those skilled in the art should know that when the power of the light-emitting diode used is extremely low, the light-emitting diode The heat dissipation fins 14 of the explosion-proof lamp 10 can be omitted, so that the upper cover sealing plate 16 can be directly fixed to the back of the explosion-proof shell 11, and the light-emitting diode explosion-proof lamp 20 can be replaced without heat dissipation fins 24.The structure of the fins in the figure. In addition, if the heat dissipation efficiency of the cooling fins 14 and 24 is still insufficient, the bottom of the explosion-proof shells 11 and 21 can be covered with a heat-dissipating copper tube or a temperature equalizing plate to assist rapid heat conduction. When the lower cover pressure plates 133 and 233 are of a square structure, the two will be combined in a tight fit or glued manner without a thread design.
再者，前述雖然是以防爆照明燈或緊急照明燈為例，然熟習此藝者應知，類似之結構亦可延伸使用於例如是單面或雙面之緊急出口指示燈或避難方向指示燈等各種不同用途之燈具。另外，發光二極體燈板除了可以是配置有電源驅動電路之DOB(Driver on Board)外，也可以使用表面黏著技術(Surface Mount Technology，簡稱SMT)或COB(Chip on Board)製程技術製造之燈板，外加電源驅動電路來達成。Furthermore, although the foregoing is an example of explosion-proof lighting or emergency lighting, those skilled in the art should know that similar structures can also be extended to, for example, single-sided or double-sided emergency exit indicators or evacuation direction indicators. And other lamps for different purposes. In addition, the light-emitting diode lamp board can be a DOB (Driver on Board) equipped with a power drive circuit, or it can be manufactured using Surface Mount Technology (SMT) or COB (Chip on Board) process technology Lamp board, plus power drive circuit to achieve.
雖然本創作已以較佳實施例揭露如上，然其並非用以限定本創作，任何熟習此技藝者，在不脫離本創作之精神和範圍內所作之各種更動與潤飾，亦屬本創作之範圍。因此，本創作之保護範圍當視後附之申請專利範圍所界定者為準。Although this creation has been disclosed in the preferred embodiment as above, it is not intended to limit this creation. Any changes and retouching made by those skilled in this art without departing from the spirit and scope of this creation are also within the scope of this creation. . Therefore, the scope of protection of this creation shall be determined by the scope of the attached patent application.
