Problems solved by technology

Fluorescent light bulbs appeared after incandescent light bulbs. Although they are energy-saving and brighter, they are not environmentally friendly due to the large amount of fluorescent powder used.
At present, more energy-saving and environmentally friendly LED light sources have emerged, and LED bulbs have been produced. The existing LED bulbs generally have complex structures, mainly including three parts-lamp caps, necks, and luminous spherical surfaces. The lamp caps are all standard parts, and the neck Generally, there are two kinds of materials, plastic and metal, and the neck is generally opaque, which is mainly used for connection and heat dissipation or placing the driver. The luminous spherical surface generally has two kinds of materials, plastic and glass, which are used for light transmission, so its shape and internal structure Compared with ordinary incandescent bulbs, there is a big difference
[0003] In the existing LED light bulbs, the light emitting direction of the LED is generally forward. Due to the limitation of the light emitting angle of the LED itself, the light of the existing LED light bulbs has a taper angle, which cannot be the same as the traditional incandescent light bulbs and fluorescent light bulbs. shine in all directions
After using LED bulbs to replace incandescent bulbs and fluorescent bulbs and put them into the lamps, due to the difference in luminous mode, the luminous effect will be quite different from that of incandescent bulbs and fluorescent bulbs, which cannot achieve the luminous effect of lamp design, and the decorative performance is great discounted, thus adversely affecting bulb replacement
In addition, the existing LED light bulbs cannot change their light distribution curve through user adjustments to achieve the required light distribution effect.

Embodiment 1

[0023] Such as Figure 1 ~ Figure 4 As shown, the LED light bulb of this embodiment includes a lamp cap 1, a bulb shell 2, a drive circuit assembly box 3, an adjustment screw 4, a limit block 5, a conductive sheet 6, an intermediate threaded connecting rod 7, a support member 9, an adjustment rod 8, Two fixing blocks 10, two steel wire sleeves 13, several groups of side light-emitting components, top-emitting LED circuit board 15, the bulb shell 2 is a closing type bulb shell, and the tail of the bulb shell 2 is fixed to the lamp cap 1 connection, the tail of the lamp cap 1 is provided with an insulating part 18, the model of the lamp cap 1 is E27, of course, it can also be other models such as E26 or E14 or E12 or GU10 or GU5.3 or B22, and the bulb 5 The shape is pear-shaped, and of course it can also be in other shapes such as spherical or candle-shaped. The bulb shell 5 is made of plastic as an integrated structure, and of course it can also be made of glass. The bulb shell...

Embodiment 2

[0025] Such as figure 1 , Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that: the adjusting screw 4 of this embodiment passes through the limit block 5 and is directly connected with the bottom of the adjusting rod 8 through a screw thread, so this embodiment Example does not need the intermediate threaded connecting rod 7 of embodiment one.

[0026] The remaining features of this embodiment are the same as those of Embodiment 1.

Abstract

The invention discloses an adjustable light distribution type LED lamp, which comprises a lamp holder (1), a driving circuit component box (3), an adjusting screw (4), a limiting block (5), a conducting plate (6), a supporting piece (9), an adjusting rod (8), a fixed block (10), a steel wire sleeve (13) and a plurality of sets of lateral light emitting components, wherein the lamp holder (1) is provided with an insulating part (18); each set of lateral light emitting component comprises two bar LED circuit boards (11) and two connecting pieces (14); the two bar LED circuit boards (11) are hinged and hinged with the connecting pieces (14) by pins (12); the adjusting rod (8) slides relative to the fixed supporting piece (9); the adjusting screw (4) is in rotation connected with the insulating part (18); the limiting block (5) axially limits the adjusting screw (4); the fixed block (10) is fixed on the supporting piece (9) and the adjusting rod (8); the steel wire sleeve (13) connects the connecting pieces (14) arranged above and below each set of lateral light emitting component respectively in series; and the adjusting screw (4) drives the adjusting rod (8) to axially move along the center of the supporting piece (9).

Description

technical field [0001] The invention relates to an LED light bulb with adjustable light distribution. Background technique [0002] Traditional light bulbs are incandescent light bulbs with low illuminance, dim light and no energy saving. After the incandescent light bulb, the fluorescent light bulb appeared. Although it is energy-saving and bright, it is not environmentally friendly due to the large amount of fluorescent powder used. At present, more energy-saving and environmentally friendly LED light sources have emerged, and LED bulbs have been produced. The existing LED bulbs generally have complex structures, mainly including three parts-lamp caps, necks, and luminous spherical surfaces. The lamp caps are all standard parts, and the neck Generally, there are two kinds of materials, plastic and metal, and the neck is generally opaque, which is mainly used for connection and heat dissipation or placing the driver. The luminous spherical surface generally has two kinds o...
