Abstract

The utility model relates to an LED (Light Emitting Diode) sharp bulb with a power supply insulation cover. The LED sharp bulb with the power supply insulation cover comprises a lamp cover, an LED light emitting part, a heat dissipation block, a circuit board, a lamp holder, a cylindrical sealing box and a rear side insulation sealing cover, wherein the circuit board is provided with a power supply functional circuit, the center of the heat dissipation block is provided with a round containing hole, the cylindrical sealing box is made of insulation material and is used for containing the circuit board, the cylindrical sealing box is sleeved outside the circuit board and is positioned in the containing hole, the front end and the rear end of the cylindrical sealing box are respectively, mutually and fixedly connected with the LED light emitting part and the rear side insulation sealing cover, the lamp cover is sleeved on the LED light emitting part and is fixedly connected with the heat dissipation block, the front part of the lamp holder is mutually and fixedly connected with the tail end of the rear side insulation sealing cover, and the cylindrical sealing box and the rear side insulation sealing cover are made of heat-resisting PP (Polypropylene) plastic or bakelite. Due to the structure, the situation of breakage of the cylindrical sealing box or the rear side insulation sealing cover is not easily caused, electronic components on the circuit board are enabled not to be damaged, and in addition, electric shock phenomenon can be prevented from happening.

Description

The LED point bulb that has the mains isolation cover

Technical field

This area relates to a kind of LED point bulb, relates in particular to a kind of LED point bulb that has the mains isolation cover that is provided with insulating boot in the power module outside mask.

Background technology

LED point bulb is a kind of broad-spectrum family expenses novel energy-conserving lamp, LED point bulb can provide bigger for the power of lamp at present, the power module of LED and the consideration that the illuminating LED lamp module is in heat radiation at present, basically all be to use insulating materials such as insulating tape or heat-shrink tube that the power supply of LED point bulb is wrapped, insert then in the aluminum alloy casing of LED and insulate, because insulating tape or heat-shrink tube are damaged easily, therefore this mode dielectric strength is not high, particularly the power that generated heat at work of power unit is higher, when therefore long-term, heat-shrink tube or insulating tape can bear high temperature always, heat-shrink tube or insulating tape meeting deliquescing after long-term the use, if shake or working environment relatively poor, the situation that insulating materials destroys takes place easily, this will be easy to cause the damage of power supply to lose efficacy, even can cause safe addiction to suffer to personnel, how to avoid the generation of this situation effectively, be that people need the conscientiously problem of solution, in addition, because the power module of at present common various LED, usually all be arranged in the space in the radiating block of heat transmission, to reduce the volume of LED point bulb, but when power module in when work, the temperature of radiating block can be higher, high temperature can influence the stability of power module for a long time, even the performance of reduction insulating materials and electrical equipment, for LED point bulb, avoid the direct radiation of radiating module to power module, also often become the key that improves the power module job stability.

The utility model content

The utility model is in order to overcome the shortcoming of prior art, a kind of LED point bulb that has the mains isolation cover with good insulation performance function to be provided.

For achieving the above object, the LED point bulb that has the mains isolation cover of the present utility model has adopted following technical scheme: the LED point bulb that has the mains isolation cover of the present utility model, comprise lampshade, the LED illuminating part, radiating block, be provided with the circuit board of power supply function circuit, lamp holder, radiating block central authorities are provided with circular containing hole, this LED point bulb that has the mains isolation cover also includes cylindric seal box and the rear side insulated enclosure lid that the insulation material is made ccontaining circuit board, the sealing box is sheathed on the circuit board outside, place in the described containing hole, before the seal box, back two ends respectively with the LED illuminating part, rear side insulated enclosure lid is mutually permanently connected, lampshade is sheathed on the LED illuminating part fixedlys connected with radiating block, and the tail end of the front portion of lamp holder and rear side insulated enclosure lid is mutually permanently connected.

In the LED point bulb that has a mains isolation cover of the present utility model, the material of described seal box and back insulated enclosure lid is heat-resisting PP plastics.

In the LED point bulb that has a mains isolation cover of the present utility model, the material of described seal box and back insulated enclosure lid is a bakelite.

Beneficial effect: the LED point bulb that has the mains isolation cover of the present utility model that has adopted above-mentioned technical scheme, can guarantee in the process of work, wiring board can directly not contact with radiating block, can also reduce the temperature of circuit board effectively, and because seal box can provide good obstruct and insulation effect, even therefore on the wiring board exposed electrode is arranged, yet can not contact simultaneously and be short-circuited because of bare electrode with radiating block, the damage of electronic component on the wiring board not only can be avoided, and the phenomenon of getting an electric shock can be avoided.

Below in conjunction with accompanying drawing the utility model is described in detail, so that above-mentioned advantage of the present utility model is clearer and more definite.
