Description

A kind of LED lamp

[technical field]

The utility model relates to a kind of lighting device, especially refers to a kind of LED lamp.

[background technology]

In recent years, long service life, the energy consumption of light-emittingdiode (light emitting diode, LED) are low, the saving energy is remarkable, and LED is widely used in daily life as light source.For example at present developed the LED lamp that can be directly installed in common bulb socket, to replace existing bulb lamp.The LED bulb lamp of selling on market substantially all comprises lamp holder, lampshade, aluminium base and is installed on the LED light source on aluminium base.The bottom of aluminium base is provided with heat abstractor, and lamp holder is fixed on the bottom of heat abstractor, and lamp holder and LED light source are electrically connected, and lampshade is mounted on aluminium base, for covering LED light source.

Yet, the characteristic of LED lamp and traditional bulb lamp (such as osram lamp etc.) are very different, because LED lantern festival produces a large amount of heats, so LED light source need to be fixed on to aluminium base or other have on the substrate of thermolysis, then by aluminium base, heat is delivered to heat abstractor, thereby by instant the shedding of the heat of LED light source.LED lamp ability normal operation like this, otherwise be exactly to cause shorten the service life of light-emittingdiode, even burn out.In addition, LED light source needs DC driven, and general electric main is driving LED light source directly, and therefore, LED lamp need to add power supply changeover device AC power is converted to dc source.

Current LED lamp is normally arranged at LED light source and power supply changeover device respectively on different substrates, be made with like this two benefits, the one, cost is lower, because aluminium base etc. have the price of substrate of thermolysis higher, power supply changeover device is arranged to another substrate, escapable cost; The mechanism design of the 2nd, LED lamp is easier to, because the volume of LED bulb lamp is little, is divided into comparatively elasticity of design that two less substrates easily put ，Qie external form mechanism than a large substrate.Yet be divided into the problem of two substrates with regard to considering to connect, general way is to weld two wires to connect LED substrate and drive circuit board, but due to aluminium base good heat dissipation effect, wire will pass heat abstractor and aluminium base, relatively trouble, welds location and waits also inconvenient.On the other hand, in modern science and technology, demand small-sized, frivolous, cost degradation that LED bulb lamp also has, utilizes cable to weld to be electrically connected the structure of LED substrate and drive circuit board, is unfavorable for the Miniaturization Design of LED bulb lamp.

Therefore,, in order to overcome above-mentioned defect, be necessary to provide a kind of improved LED lamp.

[specific embodiment]

Please refer to shown in Fig. 1 to Fig. 2, the utility model LED lamp 100, comprises substrate 1, is fixed on LED light source 11 and the drive circuit board 2 of substrate 1.Substrate 1 has fluting 12, and drive circuit board 2 has linking arm 21, and the linking arm 21 of drive circuit board 2 inserts fluting 12 and is electrically connected to substrate 1.Fluting 12 is positioned at substrate 1 side makes the edge of substrate 1 form breach.

In the present embodiment, linking arm 21 has two, and it is parallel to each other that 2 liang of side direction substrates of self-driven circuit board, 1 direction is extended 2, two linking arms 21, and the position of slot 12 position and linking arm 21 is corresponding makes linking arm 21 can insert fluting 12 and through slotting 12.Thereby drive circuit board 2 needs a positive pole, a negative pole to be electrically connected to driving LED light source 11 with substrate 1 respectively conventionally, and therefore two linking arms 21 are negative pole of a positive pole.Each linking arm 21 has electrical junction (not shown), and electrical junction is for being electrically connected with substrate 1.In the present embodiment, 12 sides that are positioned at substrate 1 of slotting form breach, thereby need to perforate in the middle of substrate 1.Due to light source 11 being installed on substrate 1, and thereby perforate side need to arrange the conductive part (not shown) being electrically connected with corresponding linking arm be electrically connected to drive circuit board 2.Owing to needing the certain distance in interval between conductive part and light source 11, therefore, if fluting 12 is arranged in the middle of substrate 1 or other are not the parts of side, can make substrate 1 need larger space to hold light source 11, slot 12, conductive part etc.Fluting 12 positions of the present embodiment are more conducive to the miniaturization of substrate 1.In other fact Examples, the in the situation that of permission in substrate 1 space, 12 other the non-lateral sections that also can be arranged at substrate 1 of slotting.

In the present embodiment, linking arm 21 is welded to connect with substrate 1.Concrete, the electrical junction of the conductive part of substrate 1 and linking arm 21 is electrically connected.Conductive part and LED light source 11 are positioned at the homonymy of substrate 1, on linking arm 21, have electrical junction, and linking arm 21 makes part electrical junction be exposed to substrate 1 top through fluting 12.Thereby electrical junction is connected and is realized electrical connection by the mode of welding with the conductive part on substrate 1.Conductive part and LED light source 11 are positioned at the homonymy of substrate 1, make substrate 1 need to not realize and being electrically connected to drive circuit board 2 at the opposing another side in LED light source 11, thereby facilitate the fixing of substrate 1 and install.In other embodiment, also can realize being by other means connected of the electrical junction of linking arm 21 and the conductive part of substrate 1.As long as can make the conductive part of electrical junction and substrate 1 be electrically connected.
