Description

A lamp structure using light-emitting diodes as light sources

technical field

The utility model relates to a lamp structure, in particular to a lamp structure using a light emitting diode as a light source.

Background technique

Please refer to Fig. 1 and Fig. 2 for the structure of the existing light-emitting diode as the light source, which is a three-dimensional exploded view of the structure of the light-emitting diode bulb structure of the new No. M301984 (application No. 095220939) approved and announced And combined cross-sectional schematic diagram, its structure mainly includes:

A lamp cup 2 is made of metal and is trumpet-shaped and includes a narrowed end 23 and an enlarged end 24. The enlarged end 24 is also concavely provided with an accommodating groove 21, and is placed on the ring wall 22 of the lamp cup 2 Diffuse holes 221 are arranged around the ring;

A base 1 is assembled on the narrowing end 23 of the lamp cup 2, and the base 1 also includes two power contacts 11;

A light-emitting diode light source 3 is assembled in the recessed part 211 of the accommodating groove 21 of the lamp cup 2, and is locked on the base 1 by passing through the lamp cup 2 with a screw 31;

A light source driving circuit board 4 is assembled in the accommodating groove 21 of the lamp cup 2 through bolts 41, and the light source driving circuit board 4 is electrically connected to the LED light source 4 and the light source respectively. The two power contacts 11 of the base 1 include a central opening 42 , the LED light source 4 is located in the central opening 42 and emits light through the central opening 42 .

A lens 5 is assembled in the accommodating groove 21 of the lamp cup 2 and located above the LED light source 4; and

A lampshade 6 is made of plastic and tightly fitted to cover the enlarged end 24 of the lamp cup 2 .

And then through above-mentioned composition, make its structure because the light source driving circuit board 4 is set in the lamp cup 2 to have a larger space, so each electronic part on the light source driving circuit board 4 can adopt normal size design and can be convenient to assemble, and has The relatively good heat dissipation effect will not cause damage to other parts, which can improve the service life of the overall structure. The light emitting diode light source 3 with larger luminous brightness, or energy saving, or longer service life can be selected for use.

Yet because of its overall structure must be made up of components such as lamp cup 2, base 1, light-emitting diode light source 3, light source drive circuit board 4, lens 5 and lampshade 6 etc., therefore, make components seem quite numerous and diverse, relatively make each of them When the component is initially produced, relatively more molds need to be opened, which virtually increases its production cost. In particular, in order to reduce the operating temperature of the light source driving circuit board 4, it needs to be formed on the ring wall 22 of the lamp cup 2. Many heat dissipation holes 221 are arranged on the top of the lampshade 6, and many ventilation holes 61 must be arranged on the upper ring of the lampshade 6. Relatively, when the lamp cup 2 and the lampshade 6 are initially molded, it is necessary to spend a higher mold manufacturing cost; Secondly, because of the large number of components, relatively more time is spent on assembly during the assembly process, which virtually increases the assembly cost; furthermore, in particular, the LED light source 3 needs additional screws 31 One of the screws 31 is locked and assembled in the accommodating groove 21 of the lamp cup 2 by a locking tool (such as a screwdriver), and another screw 31 needs to pass through the lamp cup 2 to be locked in on the base 1; and the light source driving circuit board 4 also needs to use screws 41 to lock and set it in the accommodation groove 21 of the lamp cup 2 through a locking tool, so that the assembly process is more comparable. Troublesome, but all could be improved.

Detailed ways

The above-mentioned and other technical features and advantages of the present utility model will be described in more detail below in conjunction with the accompanying drawings.

Please refer to Fig. 3 to Fig. 9, the lamp structure of the present utility model is mainly aimed at improving the structure of lamps with light-emitting diodes as light sources, which includes:

The lamp body 7 is integrally made of a light-transmitting or light-guiding or light-gathering material (such as plastic, glass, and other light-transmitting materials), so that the lamp body 7 forms a concave space 71, and the concave shape A tapered light concentrator 72 is provided directly upward at the center of the bottom end of the space portion 71, and an accommodating groove 721 is provided at the center of the top of the light concentrator 72. A positioning flange 73 is provided around the ring, and a clamping ring groove 74 and a circuit groove 75 are provided on the periphery of the top section of the recessed space part 71 of the 7-position recessed lamp body.

The lighting group 8 at least includes a light emitting diode 81 as a light source and a light source circuit board 82 for fixing the light emitting diode. The light emitting diode 81 is accommodated in the receiving groove 721 provided on the top of the light collector 72 of the lamp body 7 .

The radiator 9 reduces the working temperature of the lighting and light-emitting group 8 due to the work and light emission through conduction, and fixes its cover at the clamping ring groove 74 set on the top periphery of the concave space part 71 of the recessed light body 7. The surface can be further provided with protrusions 91 of various geometric shapes to increase the heat dissipation area in contact with the air.
