Description

Rotary type LED bulb lamp

Technical field

The present invention relates to a kind of lighting, particularly rotary type LED bulb lamp.

Background technology

Because long service life, the energy consumption of LED lamp are low, energy savings is remarkable, so the LED lamp has been widely used in the daily life as light source, such as the LED bulb lamp.

Common LED bulb lamp, its LED lamp plate is parallel fixedly shape with radiator so that the light angle of LED bulb lamp is more even, but it often is not suitable for the occasion that those will throw light on to certain particular range, such as hospital or night the public place of entertainment.

For the problems referred to above, the LED bulb lamp that a kind of LED lamp plate and radiator are installed has at an angle appearred in the market, in order to realize forming certain angle between LED lamp plate and the radiator, often the LED lamp plate stationary plane of radiator is designed to an inclined-plane in its structure, after being installed to the LED lamp plate on the radiator like this, the lighting angle of its LED lamp plate just just with the radiator inclined-plane towards consistent, realized carrying out at indoor or outdoors the illumination of particular range.But in concrete the use, itself or Shortcomings point, its specific illumination zone can not be regulated, and uses randomness poor, has produced certain use limitation.

Summary of the invention

The objective of the invention is provides a kind of rotary type LED bulb lamp that can regulate the specific illumination scope in order to solve above-mentioned the deficiencies in the prior art.

To achieve these goals, the rotary type LED bulb lamp that the present invention is designed, comprise lamp holder, plastic feet, power supply module, radiator, LED lamp plate and lampshade, lamp holder is connected with the lamp holder link of plastic feet, the lamp plate installed surface of described radiator is the inclined-plane, the LED lamp plate is fixed on the above-mentioned lamp plate installed surface, lampshade is connected with the lamp plate installed surface, the other end of described plastic feet is provided with the button pin, described radiator is provided with the base accommodating cavity, and the inwall of described base accommodating cavity is provided with scrobicular ring, and plastic feet is plugged on and forms the power supply accommodating cavity in the above-mentioned base accommodating cavity, the button pin cooperates with scrobicular ring, and power supply module places in the above-mentioned power supply accommodating cavity.

Plastic feet is to be plugged in the base accommodating cavity of radiator in the said structure, so can relatively rotate between radiator and the plastic feet, therefore can change LED lamp plate on the radiator towards, thereby the particular light scope of regulating the LED lamp plate.

For the rotational stabilization between heat radiation body and the plastic feet, plastic feet described in the present invention is provided with the rotary stopper groove, described rotary stopper groove is near the setting of button pin, and be parallel shape with the button pin, lead to gathering sill on the described rotary stopper groove, the opening's edge that the button pin of the other end of described gathering sill and plastic feet arranges end connects; Be provided with salient point in the base accommodating cavity of described radiator, described salient point is between the opening of scrobicular ring and base accommodating cavity, the width of salient point is less than the width of gathering sill, its length is less than the width of rotary stopper groove, and salient point equates to the distance of detaining pin with the rotary stopper groove with distance between the groove simultaneously.

Excessive toward a direction rotation in order to prevent radiator, the line on the power supply module to be given around disconnected, the groove of rotary stopper described in the present invention is the segmentation shape.

When rotated, break away from the rotary stopper groove in order to prevent salient point, the surface of described rotary stopper groove is provided with friction teeth.

Because radiator and plastic feet are rotation snapping shape, necessarily there is rotary gap between the inwall of base accommodating cavity and the outer wall of plastic feet, therefore enter above-mentioned gap for the trifle in the world in can outside air, affect service life of the present invention, also be provided with the sealing ring mounting groove described in the present invention on the plastic feet, described sealing ring mounting groove is embedded with sealing ring in the sealing ring mounting groove between the lamp holder link of rotary stopper groove and plastic feet.

The rotary type LED bulb lamp that the present invention obtains, it can regulate the specific illumination scope of LED lamp plate, uses random relatively good; Job stability simultaneously of the present invention is high, long service life.
