Abstract

The utility model discloses an LED (Light Emitting Diode) bulb lamp which comprises a lamp shell, a driving power supply arranged in the lamp shell, a substrate and LED lamp beads arranged on the substrate. The upper end of the lamp shell is connected with a lamp head, and the lower end of the lamp shell is connected with a lamp shade; the lamp head is electrically connected to the substrate through the driving power supply; a heat conducting and stamping part is sleeved at the middle part of the inner wall of the lamp shell and is in interference fit with the inner wall of the lamp shell; a heat radiating and connecting piece is arranged in the lamp shell in an injection molding manner in the circumferential direction and is connected with the lower end of the heat conducting and stamping part; the substrate is sleeved in the heat-radiating and connecting piece and is in interference fit with the heat-radiating and connecting piece. The LED bulb lamp has the beneficial effects that heat generated by the LED lamp beads during the work is transmitted to the heat radiating and connecting piece through the substrate, then is transmitted to the heat conducting and stamping part and the lamp shell through the heat-radiating and connecting piece and finally is discharged by the lamp shell, the heat radiation area is larger, and the heat is prevented from being accumulated in the lamp shell, so that the heat radiation effect is better, and the service lives of the LED lamp beads are prolonged.

Description

A kind of LED bulb lamp
Technical field
The utility model relates to bulb lamp technical field, particularly a kind of LED bulb lamp.
Background technology
Bulb lamp is a kind of Novel energy-saving lamp of alternative conventional incandescent bulb, and wherein LED bulb lamp is widely used in daily life because of its energy-saving and environmental protection.Existing LED bulb lamp generally includes lamp housing, be located at driving power and substrate in lamp housing, be located at LED lamp pearl and heat abstractor on substrate, described lamp housing upper end is connected with lamp holder, described lamp housing lower end is connected with lampshade, and described lamp holder is electrically connected to described substrate by driving power.In the time of the operating illumination of LED bulb lamp, the heat that LED lamp pearl produces reaches heat abstractor through substrate, distributed by radiation by heat abstractor again, limit owing to being subject to lamp housing inner space, the heat loss through radiation area of adding heat abstractor is limited, cause heat to discharge in time, and then cause the reduction of LED light source lumen number, light decay quickening or reduction of service life etc., affect the quality of LED bulb lamp.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of simple and reasonable, area of dissipation large, the LED bulb lamp of good heat dispersion performance.
For achieving the above object, the utility model is by the following technical solutions:
A kind of LED bulb lamp described in the utility model, comprise lamp housing, be located at the driving power in lamp housing, substrate and be located at the LED lamp pearl on substrate, described lamp housing upper end is connected with lamp holder, described lamp housing lower end is connected with lampshade, described lamp holder is electrically connected to described substrate by driving power, described envelope inner wall middle part is arranged with heat conduction stamping parts, described heat conduction stamping parts and envelope inner wall interference fit, in described lamp housing, be provided with heat radiation brace along circumferential injection moulding, described heat radiation brace is connected at the lower end of described heat conduction stamping parts, described substrate be sheathed on heat radiation brace in and with described heat radiation brace interference fit.
Further, described envelope inner wall top is provided with draw-in groove, and described driving power is provided with the fixture block corresponding with draw-in groove, and described driving power coordinates with draw-in groove by described fixture block and is arranged in described envelope inner wall top.
Further, described lampshade is arranged in described lamp housing lower end.
The beneficial effects of the utility model are: compared with prior art, the utility model is by being arranged with heat conduction stamping parts at envelope inner wall middle part, described heat conduction stamping parts and envelope inner wall interference fit, in described lamp housing, be provided with heat radiation brace along circumferential injection moulding, heat radiation brace is connected at the lower end of described heat conduction stamping parts, and described substrate is sheathed in heat radiation brace and described heat radiation brace interference fit.The heat that the work of LED lamp pearl produces reaches heat radiation brace through substrate, reaches heat conduction stamping parts and lamp housing, and discharged by lamp housing through heat radiation brace, area of dissipation is larger, avoid heat to hoard in lamp housing, made radiating effect better, extended the service life of LED lamp pearl.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure:
1, lamp housing; 2, driving power; 3, substrate; 4, LED lamp pearl; 5, lamp holder; 6, lampshade; 7, heat conduction stamping parts; 8, heat radiation brace.
