The middle upper part of the light transmitting lampshade is an arc-shaped curve light transmitting part; an expansible light transmitting part extends from a bottom edge of the light transmitting lampshade towards the inner side; the light transmitting lampshade of the large-illumination plane LED bulb has simple structure and low cost; the light transmitting lampshade can increase the coverage area of the light after the light passes through the light transmitting lampshade; the coverage area of the light refracted by the light transmitting lampshade is larger than a semispherical area; therefore, the light emission angle is large; the illumination plane is larger; and the illumination range is widened; the light emitted by the LED bulb equipped with the light transmitting lampshade has larger coverage range and has larger illumination plane and illumination range.
Description
Technical field
The utility model relates to LED lampshade technical field, refers in particular to a kind of transparent lamp shade of big plane of illumination LED bulb.
Background technology
In the prior art, LED bulb top is provided with a transparent lamp shade, and transparent lamp shade is by being constituted less than hemispheric curved surface; Therefore, the light that reflects through transparent lamp shade can only cover less than in the hemispheric regional extent, the lighting angle of transparent lamp shade restriction LED bulb; Lighting angle is little, and the plane of illumination of LED bulb and illumination range are restricted, and the plane of illumination and the illumination range of LED bulb are less; Therefore, the LED bulb of prior art has improved needs.
The utility model content
The purpose of the utility model is that the deficiency to prior art provides a kind of transparent lamp shade of big plane of illumination LED bulb; The light region covered that reflects away through transparent lamp shade is greater than hemispheric zone; Lighting angle is big, and plane of illumination is bigger, improves illumination zone.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of transparent lamp shade of big plane of illumination LED bulb, the middle and upper part of transparent lamp shade are the arc-shaped curved surface transmittance section, and the bottom margin of transparent lamp shade direction to the inside extends an expansion transmittance section.
Said expansion transmittance section is the expansion transmittance section that the thin-walled light penetrating object of toroidal constitutes.
The Breadth Maximum of said expansion transmittance section shrinks from top to down and diminishes.
The interior angle of said expansion transmittance section and arc-shaped curved surface transmittance section is the obtuse angle.
Be provided with the arc-shaped transition curved surface between said arc-shaped curved surface transmittance section and the expansion transmittance section, the dual-side of arc-shaped transition curved surface links arc-shaped curved surface transmittance section and expansion transmittance section respectively.
Said arc-shaped curved surface transmittance section is the arc-shaped curved surface transmittance section of arcwall face greater than the hemisphere curved surface.
The lateral surface of the lower edge of said expansion transmittance section is provided with and is used for the card base that transparent lamp shade is fixed in the LED bulb.
The beneficial effect that the utility model has owing to the employing technique scheme: the utility model is simple in structure; Cost is low; Transparent lamp shade can increase light through the overlay area behind the transparent lamp shade, and the light region covered that reflects away through transparent lamp shade is that lighting angle is big greater than hemispheric zone; Plane of illumination is bigger; Improve illumination zone, the light that the LED bulb of the transparent lamp shade of installation the utility model sends has bigger coverage after the transparent lamp shade refraction, have bigger plane of illumination and illumination zone.

The specific embodiment
The transparent lamp shade of a kind of big plane of illumination LED bulb of the utility model sees shown in Fig. 1 to 3 that the middle and upper part of transparent lamp shade is arc-shaped curved surface transmittance section 1, and the bottom margin of transparent lamp shade direction to the inside extends an expansion transmittance section 2.
Be provided with the arc-shaped transition curved surface between said arc-shaped curved surface transmittance section and the expansion transmittance section, the dual-side of arc-shaped transition curved surface links arc-shaped curved surface transmittance section and expansion transmittance section respectively, and the light that reflects away through transparent lamp shade has the higher uniformity.
Arc-shaped curved surface transmittance section 1 is the arc-shaped curved surface transmittance section 1 of arcwall face greater than the hemisphere curved surface, increases light through the overlay area behind the transparent lamp shade, and the light region covered that reflects away through transparent lamp shade is greater than hemispheric zone.
The lateral surface of the lower edge of said expansion transmittance section 2 is provided with and is used for the card base 3 that transparent lamp shade is fixed in the LED bulb.Conveniently transparent lamp shade is fixed in the LED bulb.
The light that the LED bulb of the transparent lamp shade of installation the utility model sends has bigger coverage after the transparent lamp shade refraction; The illumination range region covered of LED bulb is greater than hemispheric zone; Make the LED bulb of the transparent lamp shade that the utility model is installed have bigger lighting angle; Plane of illumination is bigger, improves illumination zone.
Above content is merely the preferred embodiment of the utility model; For those of ordinary skill in the art; According to the thought of the utility model, the part that on the specific embodiment and range of application, all can change, this description should not be construed as the restriction to the utility model.
