Description

Light bulb construction

The present invention relates to an LED lamp, and more particularly to a lamp construction.

Please refer to the Taiwan Patent No. 130702 patent, which discloses a "series-style large Christmas decoration string with improved structure of the bulb and the lamp pedestal and the lamp cap". The bulb mainly includes:
A pillarless light bulb:
The non-card-shaped bulb is located at a lower edge of the bulb body and has a long column tubular shape, and a flat-shaped converging fitting portion extends below the joint edge, and each side of the fitting portion is provided with a bamboo shoot groove.
A lamp pedicle:
The lamp pedicle is provided with flanges on the planes on both sides below the chamber, and is matched with the bamboo shoot groove of the non-card-shaped bulb, and the bottom edge of the bottom of the lamp bud extends downwardly with a hook, and the outer ring surface of the joint portion is two The side is provided with a positioning concave groove in a cone-shaped ladder shape, and the side of the lamp pedestal has a seat hole.
A light cap:
The outer edge of the outer edge of the lamp cap is provided with a bamboo groove flange for holding the hook of the lamp pedestal, and the groove surface of the bamboo groove of the bamboo groove on both sides of the outer wall surface is provided with a rectangular convex block, which can be combined with the lamp pedestal The concave guide grooves are tapered and arranged.
a hanger:
The hanger can cooperate with the seat hole of the lamp pedestal to form a clamp.
In addition to the advantages described in the specification, we find that the light generated by the light bulb is partially transmitted through the upper part of the light cover body, and some light is carried in the light bulb. After at least one reflection, the light is emitted from the upper portion of the lampshade body, so that when the user observes the light bulb, a light-emitting image is seen in the upper portion of the light bulb, and the image is different according to the shape of the light cover body. And make changes.
However, under the thinking of modern people who emphasize energy conservation and carbon reduction, the construction of such a bulb consumes more energy when used. If LEDs are used to make such a bulb, the light emitted by the LED will advance in a straight line. When the user views the light bulb, the image of the light inside the light bulb cannot be seen. In addition, the large amount of light emitted by the LED will cause the illumination on the side of the bulb to be low. Therefore, the creator believes that there should be a light bulb that can not only have the advantages of the LED, but also allows the user to see the inside of the bulb. Imaging.

In order to solve the deficiencies of the bulbs described in the prior art, the inventors have invented a bulb construction comprising:
a base:
The top surface of the base is provided with an LED.
A transparent lampshade:
The transparent lamp cover covers the base and encloses a space with the top frame of the base.
An optical cylinder:
The optical column system is a solid cylinder and is made of a light-transmitting material, and the optical cylinder is disposed in the space and located above the LED, and the bottom of the optical cylinder is recessed inwardly to form a tapered first vacant groove, and The LED faces the first cutout.
When the light generated by the LED enters the optical cylinder, the light is diffused into light in different directions because the first notch is tapered, so when the light is emitted from the surface of the optical cylinder, the light is used. When the optical column is illuminated as a whole, and the shape of the optical cylinder is different, different visual effects are generated; when the LED is illuminated, the light system first passes through the groove wall of the first notch, due to The first notch is tapered, so that the light is scattered into light in different directions, which not only increases the chance of light being emitted laterally from the optical cylinder, but also allows light to pass through the optical cylinder and then partially The transparent lampshade generates reflection and is reflected more than once, so that part of the light is emitted from the upper portion of the transparent lamp cover, so that the user can see an image of the light above the optical cylinder.

Located above the LED (11), the bottom of the optical cylinder (3) is recessed inwardly to form a tapered first notch (31), and the LED (11) faces the first notch (31). The optical cylinder (3) located above the LED (11) means that the bottom surface of the optical cylinder (3) has a distance from the LED (11), and the bottom of the optical cylinder (3) The first notch (31) is recessed inwardly. Therefore, if the groove wall of the first notch (31) has a distance from the LED (11), the optical column is referred to in the present invention. 3) Located above the LED (11).
Referring to the second figure, as shown in the fourth figure, when the light generated by the LED (11) passes through the groove wall of the first notch (31), the light is tapered due to the shape of the first notch (31). Shaped, and scattered into different directions of light, each light is emitted from the inside of the optical cylinder (3), part of the light will be directly emitted from the upper part of the transparent lampshade (2), part of the light will be in the bulb (A) After being reflected by at least one time, it is emitted from the upper portion of the transparent lamp cover (2), so when the user views the light bulb (A), he will see an image of the light above the optical column (3) (B) And the shape of the image (B) is matched to the shape of the transparent cover (2). Preferably, the transparent lamp cover (2) gradually converges from bottom to top, so that when the light bulb (A) emits light, the user can see an image (B) of a candlestick shape formed above the optical cylinder (3).
When the light generated by the LED (11) passes through the first notch (31), since the first notch (31) is tapered, the chance of light being emitted from the side of the optical column (3) is increased. In order to increase the lateral illuminance of the bulb (A), the opportunity for the light to be emitted from the upper portion of the transparent lampshade (2) by the reflection of the transparent lampshade (2) is further increased, so that the user can be more clear See the imaging (B). From the longitudinal section of the optical cylinder (3), according to the rule of thumb, when the angle between the groove wall of the first notch (31) and the horizontal plane is 45, the image (B) seen by the user is most clear.
