Description
—种 LED灯具结构 技术领域 —LED LED lamp structure Technical field
本发明涉及一种灯具结构, 特别涉及一种采用 LED发光二极管作为光源 的投射式 LED灯具结构。 The invention relates to a lamp structure, in particular to a projection type LED lamp structure using an LED light-emitting diode as a light source.
背景技术 Background technique
目前利用光源的投射亮度来凸现出被照射物品, 或利用光线来改善室 内、 外的空间感, 或者利用光线提供照明(如车辆的照明灯)、警示作用等, 而投射式灯具正是上述用途中最常被使用的光源。 At present, the projection brightness of the light source is used to highlight the illuminated object, or the light is used to improve the sense of space inside and outside, or the light is used to provide illumination (such as the illumination of the vehicle), the warning function, etc., and the projection type lamp is used for the above purposes. The most commonly used light source.
现今一般的投射式光源, 大多都要考虑亮度和成本, 而使用卤素灯泡作 为发光源, 虽然卤素灯泡有足够的亮度, 但相对的瓦数也较高, 使得耗电量 也相对提高, 更有过热的现象产生, 在目前追求环保及省电的社会下, 用卤 素灯泡作为发光源即是一种浪费能源的光源。 因此, 近几年来针对易过热和 耗电量大的问题, 人们以 LED ( Light Emitting Diode,发光二级管) 来代 替卤素灯泡而作为光源。 如台湾实用新型 M314300号 (申请号 95222835 ) 专利公开了一种 LED投射灯, 该投射灯包括一个管座体、 发光管组、 散热鳍 片及灯盖组; 其中, 发光管组由多个 LED发光管及发光管驱动电路板组成, 管座体用以放置驱动电路板, 散热鳍片设置于管座体顶端处, 灯盖组则用以 罩住 LED, 上述结构构成一 LED投射灯, 上述结构的灯具使用多个 LED发光 管作为发光源虽然可以提供较高的亮度,但数量上使用的越多则相对就提高 了制造厂商的制造成本, 并且每一个 LED都要搭配使用一光学镜头(或称光 学透镜, lens )用以实现 LED的聚光或散光的功效, 如此就更加使制造成本 提高, 并且上述结构的灯具较复杂, 组装费时费力。 In today's general projection light sources, most of them must consider the brightness and cost, and use halogen bulbs as the light source. Although the halogen bulbs have sufficient brightness, the relative wattage is also higher, which leads to a relatively higher power consumption. The phenomenon of overheating occurs. In the current society of pursuing environmental protection and power saving, using a halogen bulb as a light source is a source of energy waste. Therefore, in recent years, LEDs (Light Emitting Diodes) have been used as light sources instead of halogen bulbs for problems such as overheating and high power consumption. For example, Taiwan Utility Model No. M314300 (Application No. 95222835) discloses an LED projection lamp, which includes a tube holder body, an illumination tube group, a heat dissipation fin and a lamp cover group; wherein, the illumination tube group consists of a plurality of LEDs The light-emitting tube and the light-emitting tube drive circuit board are composed, the tube seat body is for placing the driving circuit board, the heat-dissipating fin is disposed at the top end of the tube seat body, and the lamp cover group is for covering the LED, the above structure constitutes an LED projection lamp, the above The structure of the luminaire uses a plurality of LED illuminating tubes as the illuminating source, although it can provide higher brightness, but the more the quantity is used, the higher the manufacturing cost of the manufacturer, and the use of an optical lens for each LED ( Or optical lens (lens) is used to achieve the effect of concentrating or astigmatizing the LED, which further increases the manufacturing cost, and the luminaire of the above structure is complicated, and the assembly is time consuming and laborious.
