Abstract

The utility model discloses an LED bulb lamp which comprises a lamp cover, a PCB, an LED light source, a radiator, a power supply driving module, a lamp shell, a base and a lamp head. The PCB is fixed at the top end of the radiator. The LED light source is arranged on the PCB. The lamp cover is arranged outside the LED light source in a covering mode. The radiator is connected with the lamp shell. The power supply driving module is arranged in the lamp shell and is electrically connected with the LED light source. The base is connected to the lamp shell. The lamp head is fixed outside the base. The lamp cover is in a cylinder shape. The side wall and the end face of the lamp cover have different thicknesses. The inner side face and the outer side face of the lamp cover are provided with surfaces which are subjected to high-gloss processing. The LED bulb lamp has the advantages that the lamp cover is arranged on the LED light source in a covering mode, so that light rays emitted by the LED light source are reflected and refracted by multiple times in the lamp cover to be dispersed to different angles, under the premise that the lamp has small appearance size, the light-emitting angle reaches 300 degrees, and accordingly the lamp can replace a large-angle bulb and a common fluorescence energy-saving lamp.

Description

The LED bulb lamp

Technical field

The utility model relates to the LED lighting field, relates in particular to a kind of LED bulb lamp.

Background technology

Existing conventional LED bulb lighting angle only has 140 ° of left and right, the LED ball bubble lighting angle of large lighting angle can reach 300 ° of left and right, although its lighting angle is close to common energy-saving lamp, but its appearance and size is considerably beyond electricity-saving lamp, can't laterally be arranged in conventional lamp, more can't substitute electricity-saving lamp fully.But, in the today of pursuing environmental protection, energy-saving and emission-reduction, electricity-saving lamp is not desirable illuminating product.

The utility model content

The technical problem that the utility model mainly solves is to provide a kind of LED bulb lamp, has larger lighting angle and size less.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LED bulb lamp is provided, comprise lampshade, pcb board, LED light source, radiator, electric power driving module, lamp housing, base and lamp holder, described pcb board is fixed on described radiator top, described LED light source is arranged on pcb board, LED light source is covered with described lampshade outward, radiator is connected with described lamp housing, described electric power driving module is located in lamp housing and is electrically connected to LED light source, described base is connected on lamp housing, base is fixed with described lamp holder outward, described lampshade is cylindrical tube shape, the sidewall of lampshade and end face have different thickness, there is the surface of processing through too high light on the medial surface of lampshade and lateral surface.

Wherein, the lateral surface outwardly convex of the end face of described lampshade is cambered surface, and the medial surface of the end face of lampshade has the cambered surface of a plurality of outside depressions.

Wherein, described lampshade is for take the one-shot forming part that PC makes as raw material.

Wherein, described LED light source is small-power adopting surface mounted LED light source.

The beneficial effects of the utility model are: by lampshade is located on LED light source, the light that LED light source is sent is distributed to different angles through multipath reflection and dioptric lighting in lampshade, guaranteeing that light fixture has lighting angle under the prerequisite of less appearance and size and reaches 300 °, can substitute wide-angle bulb and common energy-saving fluorescent lamp, owing to thering is less size, also can be arranged in the luminaire body that inner space is comparatively narrow.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.

Refer to Fig. 1 to Fig. 4, present embodiment is a kind of LED bulb lamp, comprise lampshade 1, pcb board 2, LED light source 4, radiator 3, electric power driving module 5, lamp housing 6, base 7 and lamp holder 8, described pcb board 2 is fixed on described radiator 3 tops, described LED light source 4 is small-power adopting surface mounted LED light source, it is arranged on pcb board 2, be covered with described lampshade 1 outside LED light source 4, radiator 3 is connected with described lamp housing 6, described electric power driving module 5 is located in lamp housing 6 and is electrically connected to LED light source 4, described base 7 is connected on lamp housing 6, be fixed with described lamp holder 8 outside base 7.Described lampshade 1 is for take the one-shot forming part that PC makes as raw material, be cylindrical tube shape, its sidewall and end face have different thickness, the lateral surface outwardly convex of described end face is cambered surface, the medial surface of end face has the cambered surface of a plurality of outside depressions, has the surface of processing through too high light on the medial surface of lampshade 1 and lateral surface.

Refer to Fig. 2, Fig. 4 and Fig. 5, the digitized representation light intensity in Fig. 5 in annulus, its unit is cd, the digitized representation angle that annulus is outer.This uses novel employing to adopt the lampshade of high transmission rate, high diffusion, high reflection, and lampshade inwall upper surface adopts unique structural design and optical design, has realized the one-shot forming of many thickness of lampshade, has reached the purpose of uniform-light transmission; The lampshade inner and outer wall has all adopted special high light treatment process, the light that LED light source is penetrated from bottom, from lampshade inwall Multi reflection, refraction, reflex to different angles through the lampshade outer wall again, this technology, by the light multi-angle is overlapping and complementary, has been eliminated the natural flaw that irradiates from bottom to top the luminous intensity inequality because of LED light source, realized the maximization of lighting angle, as seen from Figure 5, the part that the removal light intensity is 0, its effective irradiating angle reaches more than 300 °.

Appearance structure of the present utility model, closer to the conventional fluorescent energy-saving lamp, is used the place of wide-angle light-emitting lamp at needs, can be used for substituting conventional lamp.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
