Abstract

The utility model discloses a radiator for a light-emitting diode (LED) bulb lamp. The radiator for the LED bulb lamp comprises a radiator body, wherein the radiator body comprises a metal barrel body and heat conducting plastic wrapped on an outer surface of the metal barrel body. A cavity is arranged inside the metal barrel body, and a plurality of chimney-type heat radiating pipelines are evenly distributed at the periphery of the heat conducting plastic in a surrounding mode along the longitudinal direction. A layer of modified nylon with a high heat conductivity coefficient is wrapped on the outer surface of the aluminum barrel body. The modified nylon with the high heat conductivity coefficient not only does not affect heat dissipation effect, but also has good insulation performance and effectively solves the problem that an original radiator for the LED bulb lamp can not be insulated so that security risks exist. Furthermore, the chimney-type heat radiating pipelines which are distributed at the periphery of the heat conducting plastic in the surrounding mode along the longitudinal direction takes advantage of convection heat dissipation effect of chimneys, and therefore the radiator of the LED bulb lamp has good heat dissipation effect and is simple in structure and easy to achieve.

Description

The LED bulb lamp is used radiator
Technical field
The utility model relates to a kind of radiator, relates in particular to a kind of LED bulb lamp and uses radiator.
Background technology
Characteristics such as led light source occupies more and more important position as a kind of new type light source in lighting field, it has, and volume is little, life-span length, high brightness, low in calories, environmental protection and energy saving, low, sturdy and durable, the photochromic variation of power consumption are many.At present, if the LED bulb lamp on the market with the radiator Aluminium Radiator, generally there are a lot of radiating ribs on the surface.Though this radiator can satisfy the heat radiation requirement of LED light fixture,, therefore in the high voltage environment for use, there is certain potential safety hazard because metal heat sink is on-insulated; And when LED light fixture producer is 4000V and plays Hi-pot test, adopt the light fixture of metal heat sink very easily breakdown.
The utility model content
The purpose of the utility model is to provide a kind of LED bulb lamp to use radiator to the problems referred to above, adopts the metal heat sink structure on-insulated to solve original LED bulb lamp with radiator, has the problem of certain potential safety hazard.
The purpose of the utility model is to realize through following technical scheme:
A kind of LED bulb lamp is used radiator; Comprise radiator body; Said radiator body comprises a metal cylinder and is coated on the heat-conducting plastic of metal cylinder outer surface, and said metal cylinder inside is a cavity, the periphery of said heat-conducting plastic several funnel-shaped hot channels that vertically have been periphery uniformly.
Preferably, said heat-conducting plastic is the modification of nylon with high thermal conductivity coefficient.
Preferably, the periphery of said heat-conducting plastic 12 the funnel-shaped hot channels that vertically have been periphery uniformly.
Preferably, be evenly equipped with 4 installing holes that are used to install bulb lamp bottom the said metal cylinder.
Preferably, said metal cylinder is an aluminum cylinder.
The beneficial effect of the utility model does; Said LED bulb lamp coats the modification of nylon that one deck has high thermal conductivity coefficient with radiator at the aluminum cylinder outer surface; Not only do not influence radiating effect; And modification of nylon has the good insulation performance performance, and it is on-insulated with radiator to efficiently solve original LED bulb lamp, has the problem of potential safety hazard; In addition, the funnel-shaped hot channel that the periphery of heat-conducting plastic vertically is periphery has been used chimney heat loss through convection effect, has better heat radiating effect, and is simple in structure, be easy to realize.
Description of drawings
Fig. 1 is the structural representation of the utility model LED bulb lamp with radiator.
Among the figure:
1, installing hole; 2, aluminum cylinder; 3, funnel-shaped hot channel; 4, modification of nylon.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through the specific embodiment.
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of the utility model LED bulb lamp with radiator; In present embodiment; A kind of LED bulb lamp is used radiator; Comprise radiator body, said radiator body comprises an aluminum cylinder 2 and the modification of nylon 4 that is coated on aluminum cylinder 2 outer surfaces, and said aluminum cylinder 2 inside are a cavity; Its bottom is evenly equipped with four installing holes 1 that are used to install bulb lamp, the periphery of said modification of nylon 4 12 the funnel-shaped hot channels 3 that vertically have been periphery uniformly.
Said LED bulb lamp coats the modification of nylon 4 that one deck has high thermal conductivity coefficient with radiator at aluminum cylinder 2 outer surfaces; Not only do not influence radiating effect; And modification of nylon 4 has the good insulation performance performance, and it is on-insulated with radiator to efficiently solve original LED bulb lamp, has the problem of potential safety hazard; In addition, the periphery of modification of nylon 4 12 the funnel-shaped hot channels 3 that vertically have been periphery have uniformly been used chimney heat loss through convection effect; During work, radiator makes surrounding air heat up, so atmospheric density reduces and moves upward; So negative pressure occurs in the funnel-shaped hot channel 3; Its bottom absorbs outside cold air, has realized the cold and hot exchange of air, has improved radiating efficiency.
Above embodiment has just set forth the basic principle and the characteristic of the utility model; The utility model is not limited by the foregoing description; Under the prerequisite that does not break away from the utility model spirit and scope; The utility model also has various variations and change, and these variations and change all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
