Abstract
The utility model discloses an LED bulb. The LED bulb comprises a lampshade, a lamp body, a lamp holder and LED light source modules. The upper half portion of the lamp body is a frustum of a prism, and the lower half portion of the lamp body is a cylinder. Aluminum heat dissipation fins are arranged on the side face of the cylinder in the mode of outwards extending radially, and the LED light source modules are arranged on the side face and the upper bottom surface of the frustum of a prism. Due to the fact that the LED light source modules are installed and distributed on the side face and the upper bottom surface of the frustum of a prism of the lamp body to form three-dimensional light emission, the utilization rate of emitted light is improved, heat generated by light sources can rapidly pass through the side face and the bottom surface of the frustum of a prism to be transmitted to the aluminum heat dissipation fins to be dissipated, the heat dissipation effect is excellent, and the service life of LEDs is prolonged.
Description
Technical field
The utility model relates to a kind of lamp, relates in particular to a kind of LED bulb lamp.
Background technology
LED is the abbreviation of (light emitting diode), and the advantage of LED lamp maximum is exactly energy-conserving and environment-protective.More than the luminous efficiency of light reaches 100 lumens/watt, common incandescent lamp can only reach 40 lumens/watt, and electricity-saving lamp is also just hovered in 70 lumens/watt left and right.So, same wattage, LED lamp effect can be bright more a lot of than incandescent lamp and electricity-saving lamp.The brightness of 1 watt of LED lamp is equivalent to the electricity-saving lamp of 2 watts of left and right, and the power consumption 5 in 1000 hours of 5 watts of LED lamps is spent, and the LED lamp life-span can reach 50,000 hours, and LED lamp is radiationless.Along with the enforcement of the new energy-conserving and environment-protective standard of China, LED electricity-saving lamp will become new light source.But LED lamp in the market is normally arranged on LED light source chip on the two dimensional surface of lamp body, therefore luminous utilization rate deficiency, poor radiation, has shortened service life of LED.
Summary of the invention
In view of this, technical problem to be solved in the utility model is: the utility model provides a kind of LED bulb lamp, has reached luminous utilization rate high, and thermal diffusivity is good, the object of long service life.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of LED bulb lamp, comprises lampshade, lamp body, lamp holder and LED light source module composition, it is characterized in that: the first half of described lamp body is terrace with edge, and the latter half is cylinder; On described cylindrical side, extend and be provided with aluminium radiating fin to external radiation; Described LED light source module is located on the side and upper bottom surface of terrace with edge.
The first half terrace with edge and the latter half cylinder of described lamp body are formed in one.
Described LED light source module is made up of LED light source chip and fin.
Described LED light source chip is installed on fin in the mode of serial or parallel connection.
The beneficial effects of the utility model: due to lamp body disposal molding of the present utility model, LED light source module is installed to be distributed in and on the side of terrace with edge of lamp body and upper bottom surface, form that 3 D stereo is luminous has improved luminous utilization rate, the heat that light source produces can be rapidly delivered on aluminium radiating fin and be dissipated by the side of terrace with edge and upper bottom surface, and radiating effect is splendid.The long service life of the LED improving.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of LED bulb lamp, comprise lampshade 1, lamp body 2, lamp holder 3 and LED light source module composition 4, the first half of lamp body is terrace with edge 21, the latter half is cylinder 22, the first half terrace with edge and the latter half cylinder are one-body molded, on cylindrical side, extend and are provided with aluminium radiating fin 23 to external radiation, and wherein lampshade is enclosed within on the first half terrace with edge of lamp body, lampshade bottom is installed on one end of the latter half cylinder of lamp body, and the other end of lamp body cylinder is fixedly connected with lamp holder.LED light source module is located on the side and upper bottom surface of terrace with edge, LED light source module is made up of LED light source chip 41 and fin 42, LED light source chip 41 is installed on fin 42 in the mode of serial or parallel connection, and LED light source module 4 is connected with lamp holder 3 by light source controller (not indicating in figure).
But the foregoing is only better possible embodiments of the present utility model, not in order to limit to this scope of the claims of the present utility model, therefore the equivalent structure that all utilization the utility model descriptions and accompanying drawing content are done changes, and is all in like manner included in scope of the present utility model.
