Abstract
The utility model discloses a telescopic type light-emitting diode (LED) light source which comprises a circuit board and a light head fixed on the circuit board. The circuit board is provided with at least one LED, a connecting piece is arranged between the circuit board and the light head, and the connecting piece is of a telescopic structure. By adopting the connecting piece of the telescopic structure, the telescopic type LED light source solves the technical problems that in the prior art, the light head and the circuit board cannot move after being fixed through the connecting piece and using is inconvenient, is simple in method and low in cost, can prevent the light head from being pressed and damaged, and is obvious in using effect.
Description
Technical field
The utility model relates to decorating lighting lamp, particularly relates to a kind of led light source with Telescopic.
Background technology
Raising along with people's living standard, energy savings is the major issue that we face now, at lighting field, the application of LED luminous product more and more comes into one's own, LED has the many merits such as light efficiency height, long service life, energy-saving and environmental protection, more and more is widely used in various fields, such as room lighting, outdoor lighting, backlight, medical treatment, traffic and special lighting etc.
For example, application number is CN200620127436.8, and publication number is the Chinese patent " a kind of led light source " of CN2677741, a kind of led light source is disclosed, comprise circuit board, be fixed in the lamp holder of circuit board below, the circuit board front arranges a LED at least, and back of circuit board arranges a LED at least.The product weak point of this patent is that lamp holder and circuit board can't move after adopting connector fixing, uses inconvenient.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that prior art exists, and proposes a kind of telescopic led light source.The utility model adopts the connector of stretching structure, has overcome can't move after prior art exists lamp holder and circuit board to adopt connector fixing, causes using inconvenient technical problem, method is simple, with low cost, but also can prevent the lamp holder fail in compression, result of use is remarkable.
The utility model is realized by the following technical solutions:
A kind of telescopic led light source comprises circuit board and the lamp holder that is fixed on the circuit board, is provided with at least a LED on the described circuit board, is provided with connector between described circuit board and the lamp holder, and it is characterized in that: described connector is stretching structure.
Described connector is telescoping tube or expansion link.
Described lamp holder is fixed on the center of circuit board by connector, LED be four be symmetrically distributed in lamp holder around.
Control circuit on the described circuit board is bridge rectifier.
The utility model compared with prior art, its advantage is:
1, the utility model adopts the connector of stretching structure, has overcome can't move after prior art exists lamp holder and circuit board to adopt connector fixing, causes using inconvenient technical problem, method is simple, with low cost, but also can prevent the lamp holder fail in compression, result of use is remarkable.
2, the utility model adopts telescoping tube or expansion link, and is simple in structure, easy to use, and cost is low.
3, the utility model adopts lamp holder to be fixed on the center of circuit board by connector, and LED is four and is symmetrically distributed in around the lamp holder; Improve LED light efficiency and colour rendering index, the led light source colour consistency is good.
4, to adopt the control circuit on the circuit board be bridge rectifier to the utility model, the output of bridge rectifier some the LED lamps of can connecting.
