Abstract

The utility model relates to a safe heat radiation structure for a light emitting diode (LED) bulb lamp. The safe heat radiation structure comprises the LED bulb lamp, an aluminum heat radiator 4 and a connecting seat 6, wherein a high-temperature fire-resistance plastic cement case 5 is sheathed outside the aluminum heat radiator 4, a hollow design is adopted in the middle of the aluminum heat radiator 4, and a plurality of heat conduction grooves matched with the hollow design are arranged in the plastic cement case 5. The safe heat radiation structure belongs to the device capable of enhancing the safety of the LED bulb lamp and organically combining the conduction heat radiation with the convection between the internal heat radiator of the LED bulb lamp and the case.

Description

A kind of LED bulb lamp safety radiator structure

Technical field

The utility model relates to a kind of bulb, specifically is the device that a kind of LED bulb lamp Inner heat sink and shell form convection current and heat loss through conduction combination.

Backgroundfield

The LED illumination aluminium shell that bulb lamp adopted disclosed sale and that use is directly to expose outside on the market, and the input voltage of bulb lamp is the AC230V high pressure, and the aluminium shell directly exposes the danger that electric shock is arranged when installing;, the aluminium skin temperature also can scald one's hand when raising; Have certain insecurity, and heat-dissipating casing is whole shuts, because of cross safety require that shell is directly exposed outside can not hollow out; Can not form the radiating effect of convection current; Reduced heat dispersion,, must improve this structure based on above reason.

The utility model content

The purpose of the utility model is fundamentally to solve to exist dangerous in the structure of existing LED bulb lamp and improve technical problem such as heat dispersion; A kind of LED bulb lamp safety radiator structure that provides; Strengthen the security of LED bulb lamp, can make the formation convection current of LED bulb lamp Inner heat sink and shell and the device that heat loss through conduction organically combines again.

The technical scheme of the utility model is achieved in that

A kind of LED bulb lamp safety radiator structure; Comprise LED bulb lamp and aluminium radiator; It is characterized in that: entangle at aluminium radiator external application heat-resistant fireproof plastic shell, leave the gap between aluminium radiator and the plastic shell, on plastic shell, be provided with the some thermal troughs that communicate with above-mentioned gap.

Described aluminium radiator surface hollow-out design makes plastic shell and aluminium radiator form the gap that convection current heat conduction is used.

Described LED bulb lamp comprises Transparent lamp shade, chip and self-tapping screw, and fixedly on the aluminium radiator, Transparent lamp shade all covers chip chip through self-tapping screw.

The utility model forms the structural design of convection current and heat loss through conduction owing to adopted the design of internal heat dissipating equipment hollow out to combine with the numerous thermal trough of plastic shell, makes it possess following advantage:

1, inner aluminium radiator hollow out design combines to form convection effects with the thermal trough of plastic shell, improves the heat dispersion of LED bulb lamp

2, aluminium radiator does not expose outside, and the outside is a plastic shell, not having the danger of getting an electric shock and scalding one's hand, and improves the security performance of LED.

3, because the good one-tenth performance of plastic material more has plastic colloidality, it is more perfect to use outward appearance to do, and feel is more comfortable.

4, owing to be not directly to do shell, but do shell, can reduce the shaping and the surface treatment cost of aluminium shell, thereby reduce the cost of entire product, improved cost performance with plastic material with aluminium.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment:

It is as shown in Figure 1,A kind of LED bulb lamp safety radiator structure; Comprise LED bulb lamp, aluminium radiator 4 and Connection Block 6; Entangle at described aluminium radiator 4 external application heat-resistant fireproof plastic shells 5, hollow out design in the middle of the aluminium radiator 4 is provided with the some thermal troughs that cooperate with the hollow out design on plastic shell 5.

Described LED bulb lamp comprises Transparent lamp shade 1, chip 3 and self-tapping screw 2; The chip 3 that aluminium radiator 4 connects; The heat that chip 3 distributes discharges most heat through aluminium radiator 4; Remaining heat is isolated through plastic shell 5, does not so just have the danger of getting an electric shock and scalding one's hand, and improves the security performance of LED; Inner aluminium radiator 4 and the device that plastic shell 5 formation convection current and heat loss through conduction organically combine are the insulation heat-proof quality that prerequisite increases plastic cement not influencing the radiating equipment thermal diffusivity, have so promptly increased security of products and plasticity.
