Description

The LED bulb

Technical field

The utility model is a kind of LED bulb, especially a kind of pedestal that is used in of finger is set up a protruding seat, and be attached at this protruding seat by the heat radiation adhesive tape by the LED module, with assembling speed and then the lifting productive rate of promoting the LED bulb, more increase LED bulb irradiation angle, then enlarge the illumination zone of LED bulb, and this protruding seat is formed in one with pedestal, makes and take into account radiating efficiency.

Background technology

The LED technical development is day by day flourishing, make LED be divided into different ray structures such as OLED and PLED, make LED more polynary and generally be applicable to illumination and purposes such as plane display interface, and the LED light fixture volume that is used to throw light on is little and consume the lower effect of wattage, compared to incandescent lamp bulb and Electricity-saving lamp bulb, efficiency value (lumens/watt) is maximum with LED, for example, the efficiency value of incandescent lamp bulb is about 15, longevity express contract 1000 hours; The efficiency value of Electricity-saving lamp bulb is about 65, about 10000 hours of life-span; The LED efficiency value of cold white is about 75-80, about 40000 hours of life-span; Anticipate promptly, LED power consumption is minimum and luminous efficiency is the highest, and its service life is also longer, also meets most the notion of environmental protection, and therefore, LED generally is used for flashlight and lighting.

See also shown in Figure 1, known LED bulb is established an aluminium seat 201 in conductive part 101 1 ends, this aluminium seat 201 has an accommodation space 2011, again a plurality of LED light-emitting component snap-in lock are fixed in the accommodation space 2011 of this aluminium seat 201, be sleeved on this aluminium seat 201 with semicircle lampshade 301 more at last, and become the LED bulb, only this, because LED belongs to direct light, its irradiating angle is about 20 degree, if when being used for wide-angle illumination, its illuminating effect can not show a candle to incandescent lamp bulb and Electricity-saving lamp bulb, for example, when wide-angle illumination, 100 watts of incandescent lamp bulbs on average can reach 1300 lumens; 20 watts Electricity-saving lamp bulb can reach the 1000-1200 lumen approximately; 8 watts LED bulb on average but has only the 500-600 lumen, because of LED is subject to overcoming of heat dissipation technology, make quantity rareness and the price of higher-wattage LED very expensive, if according to known construction installing LED bulb, its range of exposures as shown in Figure 1, it is unfavorable for room lighting, moreover, the LED light-emitting component is arranged in this accommodation space 2011, this aluminium seat 201 occupies the LED light-emitting component near 1/2 light emitting region, make irradiating angle only limit to semicircle lampshade, this LED bulb efficient is significantly reduced, light emitting region also can not show a candle to incandescent lamp bulb and Electricity-saving lamp bulb, make numerous consumers reduce purchase intention because of its room lighting weak effect, therefore, when being used for room lighting, the LED bulb is difficult for replacing incandescent lamp bulb and Electricity-saving lamp bulb, then make compared to incandescent lamp bulb and Electricity-saving lamp bulb more the LED bulb of power saving and environmental protection be not easy to promote, moreover, known LED bulb, its pedestal and LED light-emitting component separate to be assembled in the mode that engage locking after making again, and so assembling mode is comparatively consuming time, the throughput rate of reduction LED bulb.

In sum, known LED bulb has some problems has to be overcome:

1. many LED light-emitting component snap-in lock are fixed in the accommodation space of this pedestal, make light emitting region only be semi-circular lampshade, cause LED bulb irradiation angle too narrow and small.

2. pedestal and LED light-emitting component separate and assemble in the mode that engage locking after making again, and this assembling mode is comparatively consuming time, the throughput rate of reduction LED bulb.

In view of this, this creator is specially studied and is improved at the structure of known LED bulb, and the phase is improved the problems referred to above with a preferred configuration, and after reaching constantly test through long-term research and development, there is appearance of the present utility model the beginning.

Summary of the invention
