Example Embodiment

[0029] Example 1

[0030] figure 1 and figure 2 , figure 1 It is a schematic cross-sectional view of Embodiment 1 of the large-angle light emitting bulb of the present invention, figure 2 It is a three-dimensional schematic diagram of Embodiment 1 of the large-angle light emitting bulb of the present invention. Such as figure 1 and figure 2 As shown, the large-angle light emitting bulb of the present invention includes a base 10, a mounting base 20 disposed on the base 10, at least one light-emitting unit 30, a fluorescent bulb 40, and a lampshade 50. The mounting base 20 has an upper surface 22, a side surface 24 and a lower surface 26, the side surface 24 is connected to the upper surface 22 and the lower surface 26, and the lower surface 26 of the mounting base 20 is connected to the base 10. The light-emitting unit 30 may be substantially a light-emitting diode chip, for example, and is disposed on the upper surface 22 of the mounting base 20. The fluorescent spherical sh...

Example Embodiment

[0033] Example 2

[0034] Compared with Embodiment 1, the difference of this embodiment is that the orthographic projection area of ​​the lower surface 26 of the mounting base 20 on the base 10 can be greater than or equal to the orthographic projection of the upper surface 22 of the mounting base 20 on the base 10 Area, preferably, the orthographic area of ​​the lower surface 26 of the mounting base 20 on the base 10 is greater than the orthographic area of ​​the upper surface 22 of the mounting base 20 on the base 10, that is, the difference between the upper surface 22 and the side surface 24 The included angle θ is greater than 90 degrees. For example, such as figure 1 and figure 2 As shown, the angle θ between the upper surface 22 of the mounting base 20 and the side surface 24 may be 115 degrees, for example, and the orthographic projection area of ​​the lower surface 26 of the mounting base 20 on the base 10 is larger than that of the mounting base The orthographic proje...

Example Embodiment

[0035] Example 3

[0036] Compared with Embodiment 1, the difference of this embodiment is that the vertical distance D1 from the upper surface 22 of the mounting base 20 to the base 10 is between 3 / 10 and 7 / 10 of the height H1 of the lampshade 50. Specifically, since the function of the mounting base 20 is to increase the height of the light-emitting unit 30 to increase the light-emitting angle of the bulb, the applicant of the present invention has found that when the distance D1 is between 3 / 10 of the height H1 of the lampshade 50 At 7 / 10, the light output angle of the bulb is the best. If the distance D1 is less than 3 / 10 of the height H1 of the lampshade 50, since the light is more likely to be blocked by the mounting base 20 and the base 10, in addition to the poor light angle of the bulb, the light-emitting unit 30 and the lampshade 50 are too far apart. It will cause a slight decline in luminous flux or change the light shape; and if the distance D1 is greater than 7 / 10 ...

Abstract

The invention provides a wide-angle glaring lamp, which comprises a base; an installation base, which is equipped on the base, wherein, the installation base is provided with an upper surface, a side surface and a lower surface, and the side surface connects the upper surface and the lower surface, wherein, the lower surface of the installation base connects the base, and an included angle is between the upper surface and the side surface of the installation base, and the angle is between 90-130 degrees; at least one illumination unit is equipped on the upper surface of the installation base; a fluorescence housing is equipped on the upper surface of the installation base for covering the illumination unit; and a lampshade is equipped on the base for covering the fluorescence housing, the illumination unit and the installation base, thereby improving the glaring angle of the LED lamp.

Description

Technical field [0001] The present invention relates to a light bulb, in particular to a light bulb with a large angle. Background technique [0002] The progress of science and technology and the development of people's livelihood and economy have brought a comfortable and more convenient life for mankind. In addition to providing the necessary light for life at night, lighting fixtures also play an important role in work and business activities during the day. LED has the advantages of low energy consumption, long service life, no flicker, and low pollution. Therefore, it is a trend to replace traditional tungsten bulbs with LED bulbs. [0003] Because the assembly characteristics of the LED bulb itself are different from the traditional tungsten lamp, the LED is directly installed on the circuit board, so its light-emitting angle can not be 360 ​​degrees like the traditional tungsten lamp, but can only use the circuit board as the light-emitting plane to face away The direction...
