Abstract
The utility model relates to an LED (Light-emitting Diode) bulb lamp, which comprises a radiator, an LED luminous plate, a fixing ring, a light-transmitting shade, a driving power supply module, a connector and a lamp cap, wherein the radiator is externally provided with radiating fins, so that the radiating area can be greatly increased, the LED luminous plate and the fixing ring are sequentially fixed on the large circle end surface of the radiator, the light-transmitting shade is fixed on the fixing ring and wraps the LED luminous plate, the radiator is internally provided with the driving power supply model, the connector is used for connecting the radiator and the lamp cap, and leads are arranged among the LED luminous plate, the driving power supply model and the connector. When the LED bulb lamp is used, the waste heat emitted during the working of the LED luminous plate can be quickly radiated by the radiator and the radiating fins, so that the radiating efficiency of the LED bulb lamp can be effectively improved, and the service life of an LED luminous body can be ensured.
Description
Technical field
The utility model relates to field of semiconductor photoelectron technique, specifically a kind of LED bulb lamp.
Background technology
We know that at present, the LED lamp is progressively applied; But because the restriction of LED luminous characteristics, the radiating effect of light fixture is generally not good, especially for the LED bulb lamp; Radiating effect is all undesirable, if the used heat that the LED bulb lamp in use produces can't effectively shed, then can cause the luminous efficiency decay of illuminator; Directly the life-span to the LED bulb lamp makes a big impact, and therefore, the heat dissipation problem of LED bulb lamp needs to be resolved hurrily.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes above-mentioned prior art, and a kind of LED bulb lamp of high heat dispersion is provided.
The utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of LED bulb lamp; Comprise: radiator, LED luminous plaque, retainer ring, diffuser, driving power module, connector, lamp holder; It is characterized in that: fixed L ED luminous plaque on the large round end surface of radiator; The lower surface of retainer ring is installed on the cylindrical of radiator large round end surface, and the upper surface installs and fixes diffuser, and diffuser wraps the LED luminous plaque; Radiator inside is mounted with the driving power module; One end of connector is fixed on the roundlet end face of radiator, and the other end and lamp holder cooperatively interact and assemble, and is connected to lead-in wire between LED luminous plaque, driving power module and the company's machine.
The said LED luminous plaque of the utility model is assembled by reflection device and several LED illuminators.
The said radiator inner hollow of the utility model, external belt has outward extending heat-dissipating fin.
The utility model is owing to adopt said structure; Radiator is provided with external belt has outward extending heat-dissipating fin; And use the high-efficiency heat conduction silicone grease between LED luminous plaque and the radiator; The entire heat dissipation area of scatterer is increased considerably, improved the radiating efficiency of fluorescent tube, efficiently solve the heat dissipation problem of LED fluorescent tube.
Description of drawings
Fig. 1 is the schematic appearance of the utility model;
Fig. 2 is the member assembling sketch map of the utility model;
Fig. 3 is the radiator cross sectional representation of the utility model.
Be labeled as among the figure: 1. diffuser, the 2.LED luminous plaque, 3. retainer ring, 4. radiator, 5. the driving power module 6. connects machine, 7. lamp holder.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, the utility model relates to a kind of LED bulb lamp, comprising: radiator 4, LED luminous plaque 2, retainer ring 3, diffuser 1, driving power module 5, connector 6, lamp holder 7; Radiator 4 inner hollow; External belt has the heat-dissipating fin of outside stretching, extension, can strengthen radiating effect greatly, on the large round end surface of radiator 4 with high thermal conductive silicon fat fixed L ED luminous plaque 2; LED luminous plaque 2 is assembled by reflection device and several LED illuminators; The lower surface of retainer ring 3 is installed on the cylindrical of radiator 4 large round end surface, and the upper surface is used to install and fix diffuser 1, in after diffuser 1 installs the LED luminous plaque being wrapped in; Radiator 4 inside are equipped with driving power module 5; One end of connector 6 is fixed on the roundlet end face of radiator 4, and the other end and lamp holder 7 cooperatively interact and assemble, and is connected to lead-in wire between LED luminous plaque 2, driving power module 5 and the company's machine 6.
When the utility model used, the used heat that produces during the work of LED luminous plaque can shed rapidly through radiator and heat-dissipating fin, thereby had effectively improved the radiating efficiency and the heat dispersion of LED bulb lamp, had guaranteed the service life of LED illuminator.
