Abstract

The utility model discloses a large-angle LED ball lamp for lighting, which comprises an outer casing (1), a bulb body (2) and LED chips (3), wherein, the LED chips (3) are installed on the outer casing (1) and housed in the bulb body (2); a mounting surface is arranged at the top of the outer casing (1); and a mounting edge is arranged on the circumference of the mounting surface; the open end of the bulb body (2) is connected with the mounting edge; the LED chips (3) are mounted on the mounting surface; and the luminous surfaces of the LED chips (3) are parallel and level with the top end surface of the mounting edge. In the utility model, the problems that the rays of the LED chips in concave arrangement are given out at a smaller angle and are shielded by the outer casing are solved; and the lighting angle is enlarged to cover more than 300 degrees through the LED chips which are uniformly distributed on the circumference of the top end surface of the outer casing, as well as the 2/3-ball bulb body. The LED ball lamp has an enlarged lighting angle, and is soft and uniform in lighting.

Description

A kind of large-angle LED bulb lamp

Technical field

The utility model relates to illuminating lamp, relates in particular to a kind of LED bulb lamp that is used to throw light on.

Background technology

In modern society, advantage makes people use the illumination of LED lamp more and more widely because long-pending little, power saving of LED lamp body and life-span be long etc., but the led chip of LED lamp is designed to spill and distributes in the prior art; Limited the angle of illumination; Cause the luminous utilization rate reduction of led chip in the bulb, light angle is less, has bigger illumination dead angle; Form dash area, influenced illuminating effect; When people need widely illumination zone, have to increase the quantity of illuminating lamp, thereby wasted resource.

The utility model content

The main purpose of the utility model is: provide that a kind of lighting angle is bigger, the less LED bulb lamp in illumination dead angle.

For solving the problems of the technologies described above, the utility model provides a kind of large-angle LED bulb lamp, comprises shell body, foam and led chip; Said led chip is installed in the said shell body and is enclosed in the said foam; Said shell body top is provided with an installed surface, is provided with one along the periphery of this installed surface edge is installed, and said foam openend and said installation edge join, and said led chip is installed on the said installed surface; Said led chip light-emitting area is concordant with the top end face of said installation edge.

Described led chip is evenly arranged near said installation edge on said installed surface, and described foam is 2/3 spheroid.

The beneficial effect of the utility model is: the led chip light-emitting area is concordant with described shell body top end face; Avoided being distributed in the shell body because of the led chip depression; And the light angle of sending diminishes, and reduces blocking of light that shell body sends led chip as far as possible, thereby can enlarge the light angle and the scope of light; Dwindle the illumination dead angle and the dash area of light fixture, promote illumination efficiency and illuminating effect.The utility model is particularly useful for applied environments such as up pendent lamp of bulb, wall lamp.

Further, led chip is evenly arranged near said installation edge on said installed surface, and the diffuse reflection of the foam through 2/3 spheroid makes the angle of illumination become big, thereby lighting angle is increased to more than 300 °.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the application sketch map of the utility model embodiment.

The specific embodiment

Combine accompanying drawing that the utility model is done further explain through the specific embodiment below.

A kind of large-angle LED bulb lamp as shown in Figure 1 comprises shell body 1, foam 2, led chip 3, power module and E27 power connection; Power module is installed on shell body inside; The E27 power connection is connected to the shell body bottom mutually, and is electrically connected with power module; Shell body 1 adopts heat radiation pottery or metal material, and adopts the conventional design that as far as possible increases surface area, can led chip 3 and the heat that power module produces be distributed as early as possible.Shell body 1 top is provided with an installed surface; Periphery along this installed surface is provided with an installation edge; Foam 2 openends join for fastening or screwing with the installation edge, and led chip 3 is installed in the said shell body 1, and led chip 3 is evenly arranged near the installation edge on installed surface and is enclosed in the foam 2; Led chip 3 light-emitting areas are concordant with the top end face that edge is installed, and avoided the light of led chip outgoing to be stopped by shell body 1 as far as possible, the angle of beam projecting and wider, and illumination efficiency and illuminating effect are better.Preferably, foam 2 adopts 2/3 spheroid form, shell body 1 top end face and foam 2 in the formed angle of outer tangent line of this junction sphere within 30 °.Foam 2 adopts ground glass or cated half to pass through material, can produce optical effects such as casual emission, refraction to light, makes this routine LED bulb lamp, and the angle of beam projecting and wider can reach about 300 degree.

As shown in Figure 2, this routine large-angle LED bulb lamp 5 is installed on the female seat of power supply opening upwards in the wall lamp cover 4 of design, and the utility model is suitable for being applied to similar wall lamp, pendent lamp etc.In this type of is used because the foam of LED bulb lamp upwards, can stay in the bottom irradiate light less than dash area, influence illuminating effect; The large-angle LED bulb lamp that this is routine, because the angle that light sends is bigger, scope is wider, dash area is reduced as far as possible, be able to remedy this kind deficiency, promotes illumination efficiency and illuminating effect.

Above content is the further explain that combines concrete embodiment that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
