Description

Bulb with omnidirectional illumination

The present invention relates to a bulb lamp, and more particularly to a bulb lamp that uses an LED as an omnidirectional illumination.

Most of the lighting fixtures used are fluorescent lamps. The life of fluorescent lamps is short, and the brightness during illumination is not very good. Therefore, it is often necessary to use a higher wattage fluorescent lamp or increase the number of fluorescent lamps to increase the illumination. The brightness makes the overall power consumption increase. The industry has developed another kind of energy-saving light bulb, which has environmental protection features such as power saving and long life, and has been widely used. However, the commercially available power-saving bulbs are distinguished by a variety of different lighting brightness specifications, and they are not provided with any structure or device that can enhance the brightness of the illumination. Therefore, a power-saving bulb of a brightness specification can only produce a fixed illumination brightness, and the power-saving bulb consumes. The power rate is proportional to the brightness of the illumination. If the user uses a power-saving bulb with a high illumination level, the power consumption rate will be higher.

The circuit device 16 receives an external power through the metal lamp holder 18 to control the LED module 14 Glowing. Although the LED bulb structure saves electricity compared with the traditional bulb, it can meet the advantages of green energy and environmental protection. However, the illumination of the LED is emitted in one direction, and the illumination angle is limited, so the illumination direction will be concentrated in a predetermined area; Designed as a semi-spherical sphere, the light-emitting range is small, focusing only on the top of the lampshade 10, so that the two sides and the lower part emit less light, and the opposite lateral illumination is very weak, which cannot achieve the omnidirectional illumination of the general bulb or the lamp.

In view of the above, the present invention has been directed to the absence of the above prior art, and proposes a bulb having omnidirectional illumination to effectively overcome the above problems.

A light lamp circuit 30 and a ball lamp cover 32. In order to facilitate the user to use the lamp holder of the conventional lighting device, the bulb lamp 20 can be loaded and unloaded to the lamp holder to directly replace the conventional light bulb, so the conductive of the present invention The lamp holder 22 can be of international standard, for example, the E-type metal lamp holder is E27, E14, or the Japanese Industrial Specification (JIS) specifications, for example, the E26 metal lamp holder is for 60W incandescent light bulb installation, and the E17 metal lamp holder is E17 metal lamp holder. For 40W incandescent bulb installation. The conductive lamp holder 22 is provided with a lighting circuit 30. The conductive lamp holder 22 is provided with a spiral 34. The mounting assembly 24 includes a base 36 and a horn mounted member 38 disposed on the base 36. The outer surface of the seat 36 is provided with a screw thread 40 corresponding to the spiral pattern. The base 36 can be screwed and fixed to the conductive lamp holder 22 by the corresponding spiral pattern 34 of the screw 36, and the lighting circuit 30 is interposed between the conductive lamp holder 22 And between the bases 36.

The first light-emitting module 26 is disposed above the base 36 and includes a substrate 46 and a plurality of substrates 46. The first light-emitting diode element 48 has a through-hole 50 corresponding to the first connecting portion 42 at an intermediate portion of the substrate 46. The horn-shaped mounting member 38 has a narrow to wide configuration, and the narrow end has a second connecting portion 44, such as an internal thread.

The material of the spherical lamp cover 32 can be transparent. Light plastic or glass. The lighting circuit 30 can electrically connect the first lighting module 26, the second lighting module 28 and the conductive socket 22 by using a polarity power line, and the lighting circuit 30 drives the first light through the electric power provided by the conductive socket 22. The module 26 and the second lighting module 28 emit light.

Since most users connect a 110 volt or 220 volt commercial power source as a power source for the lighting device, when the bulb lamp 20 is mounted on the socket of the lighting device, the lighting circuit 30 can be AC to DC (A/D). The converter can convert the AC power of the mains into a DC power that can be electrically connected to the light-emitting diode components within 1-10W, thereby driving the first light-emitting module and the second light-emitting module to emit light.

Please also refer to FIG. 4 , which is a schematic diagram of the illumination distribution of the present invention. Since the spherical lamp cover 32 is a spherical surface body, the irradiation area can be increased and a light source diffusion angle is better. When the first light emitting module 26 and the second light emitting unit are used, When the module 28 is simultaneously illuminated, the front end of the bulb 42 covers the range of the light projection angle of the second illumination module 28, and the second illumination module 28 projects a light source directly through the front end of the bulb 32 to Form a forward illumination state. It should be noted that the second light-emitting module 28 is disposed in the groove 52 having an inclined surface above the wide end of the horn-shaped mounting member 38. Therefore, the second light-emitting module 28 can directly transmit the light source and can pass through the concave portion. The inclined surface in the groove 52 changes the light path, so that the light coverage range can be increased, thereby increasing the light source diffusion angle, and the illumination performance of the second light-emitting module 28 can be more fully utilized.

The first light-emitting module 26 is located between the horn-shaped mounting member 38 and the pedestal 36. The wide-end diameter of the horn-shaped mounting member 38 is less than or equal to the diameter of the pedestal 36. It is worth noting that when the first illuminating module 26 projects When a light source is used, the light source will have a narrow to wide side curved surface along with the horn-shaped mounting member 38, and the side curved surface can change the light path, so that the light source of different paths can be reflected to the outside of the spherical lamp cover 32. This allows the light source to be illuminated towards the periphery, and the light source expands at a wider angle to form a lateral illumination state.

It can be seen from the above that the present invention utilizes the special structural design of the configuration and the mounting component mounted with the light-emitting module, so that the light expanding angle is wider and the lighting effect is more evenly spread, thereby achieving the full range of forward illumination and lateral illumination. The effect of directional lighting.
