Abstract
The utility model discloses a light-emitting diode (LED) lamp bulb with light pipes. The LED lamp bulb comprises a lamp holder (1), a lamp insulating bottom shell (2), a pair of LED chips (5), a driving power supply (4), an LED chip substrate (6), annular flange rib radiators (3) and a non-light tight bulb shell (7), wherein the insulating bottom shell is fixedly connected with the lamp holder; the driving power supply (4) is positioned in the insulating bottom shell (2) and in a cavity formed by the annular flange rib radiators (3), and is electrically connected with the LED chips (5) and the lamp holder (1) respectively; and the non-light tight bulb shell (7) is fixedly connected with the upper edges of the annular flange rib radiators (3). The LED lamp bulb is characterized in that: the visible light pipes (8) are fixed on the LED chip substrate; and the LED chips (5) are positioned inside the light pipes respectively. Compared with the prior art, the LED lamp bulb emits uniform and soft light, and has a larger light-emitting angle; and the light pipes are positioned on the LED chips, and are favorable for exporting the heat of the LED chips, so that the LED lamp bulb has higher radiation performance.
Description
Technical field
The utility model relates to the LED lighting device, in particular, has the LED bulb of light pipe.
Background technology
At present, in miscellaneous artificial light source, maximum with the widest use amount of purposes of incandescent lamp and fluorescent lamp; Because improving constantly of people's standard of living, and the continuous progress of manufacturing technology, light fixture of all kinds and light source are continuous must weed out the old and bring forth the new; Make the user constantly increase, cause electric consumption on lighting amount fast lifting, therefore the demand of light fixture; LED high-efficient electric-saving light source just in response to and give birth to, and along with the development of LED technology with ripe, the performance indications of LED increase substantially day by day; At present, the light efficiency of white light LEDs has has met or exceeded the light efficiency level of ordinary incandescent lamp, and luminous flux is also increasing considerably.
Existing its chip of LED bulb generally is positioned on the LED substrate, and the chip top is guiding device not.Thereby the led chip issued light that makes relatively concentrates near the substrate, can not effectively derive, and have uneven bright spot hot spot.
The LED bulb of therefore be necessary to develop, bright dipping is even, simple in structure, easy to maintenance.
Summary of the invention
The utility model provides a kind of photoconduction to go out the LED bulb that performance is good, bright dipping is even, lighting angle is big.
The utility model technical scheme is: a kind of LED bulb with light pipe; Comprise lamp holder, lamp insulation drain pan, pair of LEDs chip, driving power, led chip substrate, annular protruding rib radiator, printing opacity cell-shell; Said insulation drain pan is fixedly connected with lamp holder; Said driving power is positioned at the cavity inside that insulation drain pan and annular protruding rib radiator are formed, and said driving power is electrically connected with said led chip, said lamp holder respectively, and said printing opacity cell-shell is fixedly connected with annular protruding rib radiator upper edge; It is characterized in that fixing tangible light pipe on the said LED substrate, two chips of described pair of LEDs chip lay respectively at the inside of light pipe.The light that LED sends is derived through light pipe and is formed the light source away from the LED substrate.
The said light pipe of the utility model is that spirality light repeatedly reflects in light pipe inside and reflection makes LED bulb lighting angle more enlarge.
The said spirality light pipe of the utility model cross section is circular, diameter 5-10mm.LED light passes through light pipe to outside space scattering after repeatedly reflecting.Whole LED bulb lighting angle is big, and light is evenly distributed.
The utility model technology is luminous evenly soft with respect to prior art, and lighting angle is bigger, and light pipe is positioned at the heat that also can help led chip on the led chip derives, thereby has better heat dispersion.

The specific embodiment
Consult Fig. 1 the utility model and comprise lamp holder (1), lamp insulation drain pan (2), pair of LEDs chip (5), driving power (4), led chip substrate (6), annular protruding rib radiator (3), printing opacity cell-shell (7); Said insulation drain pan is fixedly connected with lamp holder; Said driving power (4) is positioned at insulation drain pan (2) and the cavity inside formed of annular protruding rib radiator (3); Said driving power (4) is electrically connected with said led chip (5), said lamp holder (1) respectively; Said printing opacity cell-shell (7) is fixedly connected with annular protruding rib radiator (3) upper edge; It is characterized in that fixing tangible light pipe (8) on the said LED substrate, two chips of described pair of LEDs chip (5) lay respectively at the inside of light pipe.Light pipe (8) is a spirality, can certainly be other shapes.Spirality light pipe (8) cross section is circular, diameter 5-10mm.
Certainly the utility model can have other various embodiments under the situation that does not deviate from this practicality design, the utility model simple modification and replacement all to be belonged to the scope that the utility model claim is protected.
