Abstract
The utility model relates to a wide-angle bulb lamp which comprises a lamp holder (1), a lamp body (2), a shell (4), a power driver (8), an LED (Light Emitting Diode) lamp bead (7), a circuit board (6) and a light guide cover (5), wherein the lamp holder (1) and the lamp body (2) are in threaded connection; the upper part of the lamp body (2) is fixedly connected with the shell (4); the lower end of the lamp body (2) is fixedly connected with the circuit board (6); the LED lamp bead (7) is mounted on the circuit board (6); the light guide cover (5) covers the LED lamp bead (7); the light guide cover (5) is fixedly connected with the shell (4); the power driver (8) is arranged in the lamp body (2); the power driver (8) is electrically connected with the circuit board (6) through a power line (9); and the wall thickness of an edge port (5-1) of the light guide cover (5) is more than twice that of other parts. The light angle of the wide-angle bulb lamp can be greatly increased; the power of the wide-angle bulb lamp is twice that of a bulb lamp with a same volume; and the luminous flux is at least doubled.
Description
Technical field
The utility model relates to lighting technical field, specifically, relates to a kind of extensive angle bulb lamp.
Background technology
LED bulb lamp at present commonly used adopts a plurality of LED lamp pearls to be installed on the circuit board in the lamp body as light source, and power drives is connected through the circuit board of lead with installation LED lamp pearl, and power drives is arranged on lamp body inside.The lower end of lamp body shell is provided with light-guiding shade, and light-guiding shade covers LED lamp pearl, is used for leaded light.But existing its consistent wall thickness of light-guiding shade, the only horizontal line that LED lamp pearl sends in the bulb lamp of this structure is down dispersed, and angular has only 180 °, causes luminous flux to reduce.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of extensive angle bulb lamp that can increase substantially angular, luminous flux is provided.
The technical scheme that realizes the utility model purpose is: a kind of extensive angle bulb lamp, comprise lamp holder, lamp body, shell, power drives, LED lamp pearl, circuit board and light-guiding shade, and lamp holder and lamp body are threaded; The top of lamp body is fixedly connected with shell; The lower end of lamp body is fixedly connected with circuit board, and LED lamp pearl is installed on the circuit board, and light-guiding shade covers LED lamp pearl; And light-guiding shade is fixedly connected with shell; Power drives is positioned at lamp body, and power drives is electrically connected with circuit board through power line, and other position of mouth wall ratio, limit of light-guiding shade thickens more than one times.
Further, the outer wall of limit mouth upper end is the inclined-plane.
Further, the external wall of upper portion of lamp body is provided with the decoration trim ring, and through decorating trim ring lamp body and shell is fixed together.
After adopting technique scheme: because the structure that the light-guiding shade of bulb lamp has adopted the limit mouth to thicken; Utilize the diffuse reflection principle of light; Make light fully about up and down, evenly distribute,, can reach 240 ° so angular just can increase substantially; Power is twice than the bulb lamp of same volume, and luminous flux also doubles above.
Description of drawings

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is A-A cross-sectional schematic of Fig. 2.
The specific embodiment
For the content that makes the utility model is more clearly understood,, the utility model is done further detailed explanation below according to specific embodiment and combine accompanying drawing.
Shown in Fig. 1～3, a kind of extensive angle bulb lamp comprises lamp holder 1, lamp body 2, shell 4, power drives 8, LED lamp pearl 7, circuit board 6 and light-guiding shade 5; Lamp holder 1 is threaded with lamp body 2, and the top of lamp body 2 is fixedly connected with shell 4, and the lower end of lamp body 2 is fixedly connected with circuit board 6; LED lamp pearl 7 is installed on the circuit board 6; Light-guiding shade 5 covers LED lamp pearl 7, and light-guiding shade 5 is fixedly connected with shell 4, and power drives 8 is positioned at lamp body 2; Power drives 8 is electrically connected with circuit board 6 through power line 9, and other position of mouth 5-1 wall ratio, limit of light-guiding shade 5 thickens more than one times.
As shown in Figure 3, the outer wall of limit mouth 5-1 upper end is inclined-plane 5-2.Adopt this structure, can further strengthen irreflexive effect of light, improve angular.
Like Fig. 1, shown in 3, the external wall of upper portion of lamp body 2 is provided with decorates trim ring 3, and through decorating trim ring 3 lamp body 2 and shell 4 is fixed together.Decorate the good looking appearance that lamp ring 3 can make bulb lamp.
