Light emitting angle-adjustable bulb lamp

Abstract

The invention discloses a light emitting angle-adjustable bulb lamp, comprising a lamp cap and a lamp holder, wherein a centre shaft downwards extends out of the lamp holder, the lower end of the centre shaft is connected with a base structure with an illuminating effect, the bulb lamp further comprises a lamp body structure sleeving the centre shaft in a cylinder shape, the lamp body structure isdefined by a plurality of lamp bodies and set as a high-power illuminant, each lamp body comprises a heat dissipation plate connected to the base structure through a rotating shaft mechanism so as toswing to adjust the light emitting angle, a first LED light source structure and a light transmission cover covering the first LED light source structure, each rotating shaft mechanism comprises shaft seats which are assembled into a shaft lever, and a swing seat, each heat dissipation plate is fixed on the corresponding swing seat, each swing seat is internally provided with a rotating ring sleeving the corresponding shaft lever, first saw teeth of each rotating ring and second saw teeth on the corresponding shaft seat are mutually engaged so as to have a positioning effect on the rotation of the corresponding swing seat, and when an external force is applied on the swing seats, the first saw teeth rotate relative to the second saw teeth so as to swing and adjust the light emitting angleof the lamp bodies, so that the adjusting flexibility is high, and the bulb lamp is economic, practical and convenient.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a bulb lamp with adjustable light emitting angle. Background technique [0002] Bulb lamps are new energy-saving lamps that replace traditional incandescent bulbs. With the continuous progress and development of LED technology, bulb lamps using LEDs as light sources have been widely used in various lighting places. [0003] Existing bulb lamps generally include a lamp base, a lamp base, a radiator, an LED light source structure, and a light-transmitting cover. A radiator and a single lighting source are fixed on the lamp base. The LED light source structure is arranged on the outer wall of the radiator and faces Side lighting, the lamp body is irradiating to the side, with a single lighting source, and it is easy to appear a dark area directly under the bulb lamp, which brings inconvenience to the personnel working directly under the bulb lamp; and the LED light source structur...

Problems solved by technology

[0003] Existing bulb lamps generally include a lamp base, a lamp base, a radiator, an LED light source structure, and a light-transmitting cover. A radiator and a single lighting source are fixed on the lamp base. The LED light source structure is arranged on the outer wall of the radiator and faces Side lighting, the lamp body is irradiating to the side, with a single lighting source, and it is easy to appear a dark area directly under the bulb lamp, which brings inconvenience to the personnel working directly under the bulb lamp; and the LED light source structure and the radiator are integrated into the lamp body, once it is inside If one LED is damaged, the whole lamp cannot work normally, and the whole lamp needs to be inspected and repaired, which is troublesome to replace and causes waste of resources, which runs counter to the green environmental protection concept advocated by LED; The structure limits that the bulb lamp is difficult to set up as a high-power lighting body, which has certain limitations on the application of the bulb lamp, and uses a co-heating structure to dissipate heat, and the heat dissipation effect is not ideal, which directly affects the luminous effect and use of the bulb lamp In addition, after the radiator with LED light source structure is installed on the lamp base, the whole lamp is fixed and can only irradiate all around, the light angle is fixed, and the light angle cannot be adjusted, so the use flexibility is low , and in specific occasions, especially for large-scale lighting, traditional bulbs are difficult to meet the lighting needs, and can only be replaced with high-bay lights for large-scale lighting. , the production cost is high, but in actual use, the replacement is troublesome, and the purchase cost is increased, the replacement cost is high, it is not economical and practical, and the traditional industrial and mining lamps are very large, with problems such as large packaging volume, high packaging and transportation costs, and storage space.
