Description

A kind of low-power LED shot-light module wiring board

Technical field

The utility model relates to lighting field, relates in particular to a kind of low-power LED shot-light module wiring board.

Background technology

At present, commercial shot-light all is to use halogen tungsten lamp to do light source on the market, the advantage of using halogen tungsten lamp to do light source is that brightness ratio is higher, but also there are a lot of weak points in it, though do light source higher brightness is arranged such as halogen tungsten lamp, but when producing high brightness, also can produce very high heat, long-term work can be quickened the loss of part in the environment of high heat, also and then shorten the service life of halogen tungsten lamp, because this class halogen tungsten lamp is short service life, can produce a lot of abandons, cause environmental pollution, long-term calculation comes the cost height.The electric energy that consumes during halogen tungsten lamp work simultaneously is also bigger, has increased user's electricity charge expenditure comparatively speaking.The temperature that produces when working because of halogen tungsten lamp is higher, and long-term irradiated object aging speed is also accelerated.

Therefore, need a kind of new product to replace existing halogen tungsten lamp now especially, do the light source of commercial shot-light, can guarantee to have simultaneously the brightness that equates with halogen tungsten lamp again.

The utility model content

The utility model is at deficiency of the prior art, a kind of low-power LED shot-light module wiring board is provided, and the employing light emitting source is original halogen tungsten lamp light emitting source for the white light LEDs light emitting diode replaces, and has the high brightness of original halogen tungsten lamp simultaneously again, and energy-conserving and environment-protective, long service life.

The utility model is solved the problems referred to above by following technical proposals:

A kind of low-power LED shot-light module wiring board, comprise pcb board and the illuminating circuit of forming by the LED light emitting diode, described pcb board is made of input contact, conductor side, component side, solder side, insulating surfaces, the external electric lead of described input contact is welded on the conductor side of pcb board, be furnished with illuminating circuit on the described conductor side, also be provided with the component position hole on the described component side, the conductive feet of described LED light emitting diode is inserted solder side by the component position hole and is welded.

Low-power LED shot-light module wiring board of the present utility model has energy savings, environmental protection, and the LED module that a plurality of LED lamps of working it out are formed has high brightness, lamp advantage low in calories, low-cost.
