Description
Technical field
The utility model be a kind of be applicable to light fixture have a fin type radiating module, refer to that especially the outer rim of a kind of LED of utilization (Light Emitting Diodes) light emitting diode is provided with a plurality of radiating fins, the radiating module that the heat that it produced can be discharged rapidly.
Background technology
In the light fixture miscellaneous on the market, projecting lamp has accounted for quite fixing ratio for a long time always.Especially when various electronics Electricity-saving lamp bulbs replace the traditional fluorescent lamp pipes, projecting lamp is because its special lighting effect that can provide, and still can occupy a tiny space on light fixture market.The not only high and heating easily of power consumption of existing 110 volts halogen projection lamp, the relative life-span is also very short, have only short some months average life, in the surging age of this electricity price, not only very not environmental protection and high heat that it distributed also to cause that electric wire cocks off easily etc. dangerous unexpected.
In view of this, with LED be the projecting lamp of lighting source to replace traditional halogen projection lamp be trend of the times, utilize the characteristics such as low power consumption of LED to improve the disappearance of traditional halogen projection lamp.See also shown in Figure 1ly, Fig. 1 is the schematic appearance of existing LED projection lamp.Wherein, described existing LED projection lamp 1 mainly is made up of shell 11, voltage conversion unit 12 and LED unit 13.Described LED unit 13 and voltage conversion unit 12 are located in the described metal shell 11.By by described voltage conversion unit 12 originally 110 volts alternating current the direct current that can provide LED unit 13 to use is provided to, make the LED unit 13 can be luminous and reach the projection effect.
